    service-stage administration and Telemetry | killexams.com true Questions and Pass4sure dumps

    This chapter is from the e-book 

    if you consolidate varied services onto a Solaris Cluster installing, you necessity to subsist sure that your service stages are met even when a few capabilities dwell on the same cluster node. The Oracle Solaris OS has many aspects, such as resource controls and scheduler alternatives, to aid you obtain these goals. These useful resource allocations may also subsist defined in the projects database saved in the community in /and so forth/challenge or held in the identify carrier maps.

    The Solaris Cluster utility can bind each useful resource corporations and resources to initiatives the usage of the RG_project_name and Resource_project_name properties, respectively. here illustration suggests how to create a processor pool (containing 4 CPUs) that makes consume of the justifiable share scheduler (FSS). The processor pool is then linked to the user undertaking that limits shared remembrance utilization to 8 gigabytes. The FSS will also subsist enabled by using the dispadmin -d FSS command.

    illustration four.9. Binding a useful resource neighborhood to a challenge linked to a Processor Pool

    investigate the number of processors the outfit has the consume of the psrinfo command.

    define a four-CPU-processor set known as oracle_pset in a temporary file, after which consume the file as input to the poolcfg command.

    # psrinfo | wc -l 24 # cat /tmp/create_oracle_pool.txt create pset oracle_pset ( uint pset.min = 1 ; uint pset.max = 4) create pool oracle_pool associate pool oracle_pool ( pset oracle_pset ) alter pool oracle_pool ( string pool.scheduler = "FSS" ) # poolcfg -f /tmp/create_oracle_pool.txt

    Instantiate the configuration using the pooladm command.

    # pooladm -c # pooladm system default string gadget.comment int system.version 1 boolean system.bind-default proper string gadget.poold.goals wt-load pool pool_default int pool.sys_id 0 boolean pool.energetic genuine boolean pool.default authentic string pool.scheduler FSS int pool.significance 1 string pool.remark pset pset_default pool oracle_pool int pool.sys_id 2 boolean pool.active true boolean pool.default false string pool.scheduler FSS int pool.significance 1 string pool.remark pset oracle_pset pset oracle_pset int pset.sys_id 1 boolean pset.default false uint pset.min 1 uint pset.max four string pset.instruments population uint pset.load 17 uint pset.size four string pset.comment cpu int cpu.sys_id 1 string cpu.comment string cpu.status online cpu int cpu.sys_id 0 string cpu.remark string cpu.reputation on line cpu int cpu.sys_id three string cpu.remark string cpu.status online cpu int cpu.sys_id 2 string cpu.remark string cpu.fame online pset pset_default int pset.sys_id -1 boolean pset.default proper . . .

    Use the projadd command to bear oracle_pool the mission pool for person oracle.

    # projadd -p 4242 -ok "task.max-shm-memory=(privileged,8GB,deny)" > -okay project.pool=oracle_pool consumer.oracle # su - oracle solar Microsystems Inc. SunOS 5.10 approved January 2005 $ identification -p uid=424242(oracle) gid=424242(oinstall) projid=4242(user.oracle) $ exit # clresourcegroup create -p RG_project_name=person.oracle oracle-rg

    in a similar way, the consume of the clzonecluster command (see the clzonecluster(1M) man page), that you may bind zone clusters to pools, dedicate or limit the variety of CPUs allocated to them, and restrict the physical, swap, or locked remembrance they can use.

    Gathering Telemetry from the Solaris Cluster software

    The Solaris Cluster service-stage administration role allows for you to configure the Solaris Cluster software to accumulate telemetry records from your cluster. using this characteristic, you could collect records on CPU, memory, swap, and network utilization of the cluster node in addition to on aid businesses and gadget add-ons corresponding to disks and community adapters. by means of monitoring outfit useful resource utilization through the Solaris Cluster application, that you would subsist able to collect data that displays how a provider the usage of specific device resources is performing. which you can additionally determine aid bottlenecks, overloads, and even underutilized hardware substances. in line with this facts, that you would subsist able to allocate applications to nodes which gain the necessary materials and judge which node every application should still fail over to.

    This characteristic must subsist install the consume of the clsetup command. The telemetry facts is saved in its personal Java DB database held on a failover or global file outfit that you just should provide for its use. After the setup is comprehensive, that you can allow the telemetry on the resource corporations, select the attributes to computer screen, and set thresholds. determine 4.5 and figure four.6 exhibit the classification of output that you could receive from the consume of this characteristic.

    Figure 4.5

    figure four.5 warning showing that the write I/O expense to disk d4 has surpassed the threshold set

    Figure 4.6

    figure four.6 Public network adapter utilization telemetry gathered the consume of the carrier-stage management feature

    determine 4.5 suggests that an warning has been generated as a result of disk d4 has passed the threshold set for it.

    determine 4.6 shows the utilization of the general public community adapters bge0 and bge1 on cluster node pbaital1.

    The telemetry uses the RG_slm_type useful resource neighborhood property, which may also subsist set to one of two values: automated or guide. The default expense for the RG_slm_type property is manual. unless the RG_slm_type property expense is explicitly set to automatic when a useful resource neighborhood is created, telemetry is not enabled for the useful resource group. If the aid community RG_slm_type property is modified, resource utilization monitoring starts best after the resource community is restarted.

    When a aid neighborhood has the RG_slm_type property set to automatic, the resource community supervisor (RGM) internally generates a Solaris project to track the outfit aid utilization for complete methods encapsulated by means of the aid of the useful resource neighborhood. This monitoring happens in spite of no matter if the RG_project_name and Resource_project_name residences are set. The telemetry can music simplest the device useful resource utilization: CPU utilization, resident set size (RSS), and swap utilization for useful resource groups that gain the RG_slm_type property set to computerized.

Conversely, when RG_slm_type is determined to manual, the methods of the resource community's aid may subsist sure to the tasks named within the RG_project_name and Resource_project_name properties. besides the fact that children, the RGM will not song the gadget components they use.

    illustration 4.10. The impact of surroundings the RG_slm_type Property to automatic

    Use the clresourcegroup command to divulge the property settings for the apache-1-rg aid neighborhood.

    # clresourcegroup array -v apache-1-rg === resource companies and components === useful resource community: apache-1-rg RG_description: <NULL> RG_mode: Failover RG_state: Managed RG_project_name: default RG_affinities: <NULL> RG_SLM_type: manual Auto_start_on_new_cluster: False Failback: False Nodelist: phys-winter1 phys-winter2 Maximum_primaries: 1 Desired_primaries: 1 RG_dependencies: <NULL> Implicit_network_dependencies: real Global_resources_used: <All> Pingpong_interval: 3600 Pathprefix: <NULL> RG_System: False Suspend_automatic_recovery: False --- resources for neighborhood apache-1-rg --- . . .

    Use the clresourcegroup command to set the RG_SLM_type property to automated.

    # clresourcegroup set -p RG_SLM_type=computerized apache-1-rg # clresourcegroup array -v apache-1-rg === aid companies and resources === aid community: apache-1-rg RG_description: <NULL> RG_mode: Failover RG_state: Managed RG_project_name: default RG_affinities: <NULL> RG_SLM_type: computerized RG_SLM_projectname: SCSLM_apache_1_rg RG_SLM_pset_type: default RG_SLM_CPU_SHARES: 1 RG_SLM_PSET_MIN: 0 Auto_start_on_new_cluster: False Failback: False Nodelist: phys-winter1 phys-winter2 Maximum_primaries: 1 Desired_primaries: 1 RG_dependencies: <NULL> Implicit_network_dependencies: genuine Global_resources_used: <All> Pingpong_interval: 3600 Pathprefix: <NULL> RG_System: False Suspend_automatic_recovery: False --- components for community apache-1-rg --- . . .

    Guide to vendor-specific IT security certifications | killexams.com true questions and Pass4sure dumps

    Despite the wide selection of vendor-specific information technology security certifications, identifying which...

    ones best suit your educational or career needs is fairly straightforward.

    This lead to vendor-specific IT security certifications includes an alphabetized table of security certification programs from various vendors, a brief description of each certification and counsel for further details.

    Introduction: Choosing vendor-specific information technology security certifications

    The process of choosing the right vendor-specific information technology security certifications is much simpler than choosing vendor-neutral ones. In the vendor-neutral landscape, you must evaluate the pros and cons of various programs to select the best option. On the vendor-specific side, it's only necessary to follow these three steps:

  • Inventory your organization's security infrastructure and identify which vendors' products or services are present.
  • Check this lead (or vendor websites, for products not covered here) to determine whether a certification applies to the products or services in your organization.
  • Decide if spending the time and money to obtain such credentials (or to fund them for your employees) is worth the resulting benefits.
  • In an environment where qualified IT security professionals can choose from numerous job openings, the benefits of individual training and certifications can subsist arduous to appraise.

    Many employers pay certification costs to develop and retain their employees, as well as to boost the organization's in-house expertise. Most perceive this as a win-win for employers and employees alike, though employers often require complete or partial reimbursement for the related costs incurred if employees leave their jobs sooner than some specified payback epoch after certification.

    There gain been quite a few changes since the terminal survey update in 2015. The Basic category saw a substantial jump in the number of available IT security certifications due to the addition of several Brainbench certifications, in addition to the Cisco Certified Network Associate (CCNA) Cyber Ops certification, the Fortinet Network Security Expert Program and fresh IBM certifications. 

    2017 IT security certification changes

    Certifications from AccessData, Check Point, IBM and Oracle were added to the Intermediate category, increasing the total number of certifications in that category, as well. However, the number of certifications in the Advanced category decreased, due to several IBM certifications being retired.

    Creating fresh Resource Types | killexams.com true questions and Pass4sure dumps

    This chapter is from the engage 

    As described in the section "Data Service and Application Agents" in Chapter 2, "Oracle Solaris Cluster: Features and Architecture," Oracle has a substantial list of supported agents that cover most of the applications in your data center. These application agents are maintained by Oracle and are extensively tested on each fresh release of both the Solaris Cluster software and the application itself. Even so, inevitably you will gain an application that is not Part of the existing agent portfolio.

    Application Suitability

    Before creating a resource type for your application, you must determine whether the application meets the criteria for being made highly available. The following list highlights the main points you must consider. For a complete list perceive "Analyzing the Application for Suitability" in [SCDevGuide].

  • Is your application crash-tolerant? This is famous because in a highly available environment your application must subsist able to retrieve its data consistency without requiring manual intervention. If the application did require such intervention, then most of the benefits of a high-availability framework would subsist lost.
  • Does your application depend on the physical node denomination of the machine, such as that resulting from calls to uname, gethostbyname, or equivalent interfaces? If so, then when the application moves to another cluster node, the dependency on the physical hostname will probably antecedent the application to fail. There is a work-around to this problem, which is to interpose the libschost.so.1 library. However, this work-around can sometimes raise support issues with application vendors.
  • Can your application sprint on a multihomed system, that is, one with several public networks? Your application must subsist able to ply situations where IP addresses are configured and unconfigured from network adapters as services whisk around the cluster. This has consequences for the pass your application binds to the network.
  • Does your application consume hard-coded path names for the location of its data? If so, then symbolic links might not subsist adequate to ensure that the data is stored in a location that is compatible with using a failover or global file system. If the application renames a data file, it can atomize the symbolic links.
  • After you gain determined that your application is suitable for being made highly available, you gain several ways to achieve the necessary integration:

  • You can consume the Generic Data Service (GDS) directly and just supply the required parameters. Although you cannot define any fresh extension properties for the resource type you create, it is by far the simplest option.
  • You can create a subclass of the GDS to create a completely fresh resource type. This option enables you to define one or more extension properties for your fresh resource type. This option is relatively simple and yet provides considerable flexibility.
  • You can extend the GDS using the Advanced Agent Toolkit. Although this option does not create a fresh resource type, it does enable you to define one or more extension properties. This option is also relatively simple and provides considerable flexibility.
  • You can consume the GUI scdsbuilder implement and customize the resulting shell script or C source using the Resource Management API (RMAPI) and the Data Service progress Library (DSDL) APIs. If significant customization drudgery is needed, this option might result in an increased maintenance burden.
  • You can consume the RMAPI or DSDL APIs directly to develop your resource type from scratch. This option trades the progress and maintenance costs for ultimate flexibility and performance.
  • Each option is discussed in more detail in the following sections.

    Generic Data Service

    The Generic Data Service (GDS) is provided with the Solaris Cluster software. The SUNW.gds agent is packaged in the SUNWscgds package, which is installed as gauge by the Solaris Cluster software installer program. The SUNW.gds agent is considered the preferred pass to create both failover and scalable resources. The GDS is supported by Oracle, but you must support the script that you provide for the Start_command, Stop_command, Probe_command, and Validate_command methods.

    By default, the SUNW.gds resource type is not registered, so you must register it before attempting to create a resource of that type. The commands in the following specimen array how to determine if the resource type is registered and then how to register it, if it is not already present.

    Example 4.13. Registering the SUNW.gds Resource Type

    Use the clresourcetype command to determine whether the SUNW.gds resource type needs to subsist registered.

    # clresourcetype list | grep SUNW.gds # clresourcetype register SUNW.gds # clresourcetype list | grep SUNW.gds SUNW.gds:6

    In addition to the gauge resource properties, the GDS agent has four properties to enable you to integrate your application: Start_command, Stop_command, Probe_command, and Validate_command. These properties are described in "Integrating Your Application-Specific Logic." By using the GDS as the basis for your application, you automatically profit from complete the patches and feature upgrades that the GDS receives.

    Example 4.14 shows how you can consume the GDS to bear the X11 program xeyes highly available. You commence by creating a Start_command program. In this example, a script calls the complete path denomination of the program with a parameter that is passed to the shell script. This script must exist on complete the cluster nodes on which the application is intended to run.

    Next, having checked that the SUNW.gds resource type is registered, you create the resource group. In this example, you allow the resource group's node list to default to complete the cluster nodes.

    Next, you create a resource to delineate your program. In the example, the Start_command property is specified by the script you wrote (and which must exist on complete nodes). The array parameter to consume is also specified. Because this program does not listen on any network ports, you set the network_aware property to false. This means that the probe mechanism used will subsist the continued being of the xeyes process that the Start_command program leaves running in the background. By default, any resource you create is enabled so that when the resource group is brought online, the resource is automatically started. To change the default, you can specify the -d argument to the clresource create command.

    The terminal two steps instruct the RGM that it needs to control or manage the xeyes-rg resource group and then to bring that resource group online. The action of bringing the resource group online starts the resource because it was created in an enabled state.

    Assuming you gain allowed remote X11 clients to array on your X server using xhost and you gain specified the remedy X array to consume (substitute a value suited to your environment for myhost:1.0), then the xeyes program will parade on your display. You can switch the resource group between nodes and the RGM will destroy the xeyes process and restart it on the fresh node, phys-summer2, as the specimen shows.

    Example 4.14. Creating a Simple, Highly Available xeyes Service

    List the script that will subsist used to start the xeyes command.

    # cat /tmp/start_xeyes #!/bin/ksh /usr/openwin/demo/xeyes -display $1 & exit 0

    Check that the SUNW.gds resource type is registered, and then create the resource group and resource that will control the xeyes service.

    # clresourcetype list | grep SUNW.gds SUNW.gds:6 # clresourcegroup create xeyes-rg # clresource create -t SUNW.gds > -p start_command="/tmp/start_xeyes myhost:1.0" > -p network_aware=false > -g xeyes-rg xeyes-rs

    Use the clresourcegroup command to bring the xeyes-rg resource group online.

    # clresourcegroup manage xeyes-rg # clresourcegroup online xeyes-rg # clresourcegroup status xeyes-rg === Cluster Resource Groups === Group denomination Node denomination Suspended Status ---------- --------- --------- ------ xeyes-rg phys-summer1 No Online phys-summer2 No Offline # clresourcegroup switch -n phys-summer2 xeyes-rg # clresourcegroup status xeyes-rg === Cluster Resource Groups === Group denomination Node denomination Suspended Status ---------- --------- --------- ------ xeyes-rg phys-summer1 No Offline phys-summer2 No Online

    To demonstrate how the GDS handles application failure, quit the xeyes program from your X display. You will notice that the RGM restarts the application almost instantaneously. The messages in /var/adm/messages (see specimen 4.15) argue that the RGM recognized the failure and restarted the service.

    After the weakness probe determines that the service is online, indicated by Service is online in /var/adm/messages, destroy the process again. The resource has two properties that determine how many times it is restarted by the RGM within a inescapable time period. These properties are Retry_count and Retry_interval (see specimen 4.16). After the specified number of failures, the built-in logic of the GDS determines that the current node is unhealthy and releases the service so that it can subsist started on another node. If the service also experiences problems on this node, then the RGM will not fail the service back to its original node unless the time period, in seconds, as defined by the resource group's Pingpong_interval property, has passed. Instead, the GDS attempts to preserve the service running on the remaining node. This deportment is governed by another property called Failover_mode.

    The purpose of the Pingpong_interval property is to obviate a service that fails to start from endlessly looping, resulting in the service migrating back and forth between cluster nodes. In a test environment, you might necessity to reset the value of Pingpong_interval to a lower value. Doing so enables you to restart your service once you gain corrected any problems you encountered.

    The /var/adm/messages file contains information on the condition changes of the resource groups and resources in the cluster.

Retry, Failover Mode, and Ping-pong Interval Properties

    Use the clresource command to determine the property values of the xeyes-rs resource.

    # clresource array > -p retry_count,retry_interval,failover_mode xeyes-rs === Resources === Resource: xeyes-rs --- gauge and extension properties --- Retry_interval: 370 Class: standard Description: Time in which monitor attempts to restart a failed resource Retry_count times. Type: int Retry_count: 2 Class: standard Description: Indicates the number of times a monitor restarts the resource if it fails. Type: int Failover_mode: SOFT Class: standard Description: Modifies recovery actions taken when the resource fails. Type: enum # clresourcegroup array -p pingpong_interval xeyes-rg === Resource Groups and Resources === Resource Group: xeyes-rg Pingpong_interval: 3600

    In the preceding example, the array variable property can subsist changed only by stopping the resource and modifying the Start_command property. Although of diminutive import here, because the xeyes program must subsist restarted to change the target X server on which it displays, it does bear a dissimilarity in instances where a variable can subsist changed while a service is running. Examples include changing debugging levels to consume and changing directories for log files.

    To create a resource type that has fresh extension properties that can subsist changed when you necessity to change them, you necessity to either write your resource type from scratch or create a subclass of the GDS, as described in a later section.

    Supporting fresh Applications Using the Advanced Agent Toolkit

    Many application agents in the current Solaris Cluster software release are derived from the Advanced Agent Toolkit methodology [AdvGDSTlkit]: HA-PostgreSQL, HA-MySQL, and HA containers, to denomination three. complete three consume the SUNW.gds agent as their basis. However, in its raw form, the SUNW.gds agent has some limitations.

    The rationale behind the toolkit is that complete fresh application agents gain many common requirements:

  • They might require one or more extension properties.
  • They must provide debugging information.
  • They might necessity to disable the process-monitoring facility (pmfadm) for applications that leave no obvious child processes to monitor.
  • They must supply a Start_command script, as a minimum, and possibly Stop_command, Probe_command, and Validate_command scripts.
  • The toolkit also simplifies much of the drudgery needed to ply Oracle Solaris Zones and SMF. Thus, providing this extended framework enables your developers to focus on the application-specific integration drudgery rather than on debugging the framework itself. After the drudgery is complete, the fresh resource type is registered using a registration script.

    Developing Resource Types by Creating a Subclass of the GDS

    The edge of creating a subclass of the GDS, rather than writing a fresh resource type from scratch, is that the fresh resource type inherits complete the best practices that are already Part of the gauge GDS code. In addition, creating a subclass of the GDS enables you to create your own resource type extension properties while retaining the same even of flexibility as if you had started from scratch. Finally, your fresh resource type, which is a subclass of the GDS, has a several name, enabling you to easily distinguish resources of the fresh resource type. If you instead used the Advanced Agent Toolkit or the SUNW.gds agent, then you would gain to determine what the resource is by examining the extension properties or reviewing the code. This step would subsist necessary because the resource type would subsist set to SUNW.gds, rather than MYCORP.appsvr, for example.

    You create a subclass of the GDS by creating a resource type registration (RTR) file where the RT_basedir parameter is set to the directory containing binaries used by the gauge GDS methods: Start, Stop, Validate, and so on. You then extend the RTR file by defining your own resource type extension properties. Finally, you set the fashion parameters in the RTR file to point to your scripts that override the gauge GDS behavior.

    Several existing Sun resource types are implemented this way, including the HA-Logical Domain agent (SUNW.ldom), which was covered in the section "Failover Guest Domains" in Chapter 3, "Combining Virtualization Technologies with Oracle Solaris Cluster Software."

    The RTR file for the SUNW.ldom resource type is shown in specimen 4.17. In this RTR file, the RT_basedir parameter is set to the gauge directory for the GDS package, that is, /opt/SUNWscgds/bin. Of the gauge methods, only Init, Boot, and Validate gain been overridden using programs that are located in the ../../SUNWscxvm/bin directory. Unlike a gauge GDS resource type, the Start_command, Stop_command, Probe_command, and Validate_command properties are assigned fixed values and cannot subsist changed. This is indicated by the Tunable = zilch settings. Furthermore, each command, apart from validate_command, is called with a consistent set of arguments, namely, -R %RS_NAME -T %RT_NAME -G %RG_NAME. The %variable construct is similar to the $variable syntax establish in shell scripts. It means that when a resource of this type is instantiated, consume the names you assigned it as arguments. For example, if you wrote a resource type called FOO.bar and then created a resource group called whizz-rg containing a resource called bang-rs of this type, the argument passed would subsist -R bang-rs -T FOO.bar -G whizz-rg. With these arguments, you can then bear calls to the RMAPI or DSDL APIs to retrieve or set properties.

    In contrast to the Start_command, Stop_command, and Probe_command properties, the Validate_command property does not consume this construct. Instead, the RGM passes the validate command complete the properties listed for the resource type on the command line. Then the validate command parses this list and determines whether the configuration is valid.

    Example 4.17. RTR File for the SUNW.ldom Resource Type

    The following text shows some of the key parts of the RTR file for the SUNW.ldom resource type:

    To customize an agent beyond what is permitted by the GDS, you can consume the Agent Builder command, scdsbuilder (see the scdsbuilder(1HA) man page). This command has three code generation options, and the resulting files are wrapped in a Solaris package that you can install on your cluster nodes:

  • DSDL code (see the section "Data Service progress Library").
  • ksh code, including complete the necessary scha_control commands (see the section "Resource Management API"). With the ksh code, you are creating your own resource type.
  • A ksh registration script for a GDS agent. Here, the code generates the commandeer clresource create command.
  • You can customize the resulting code to your specific needs. However, with the ksh registration script for the GDS agent, the scope for modification is limited. The specimen in figure 4.7 shows the consume of the third option.

    Figure 4.7

    Figure 4.7 Using the scdsbuilder GUI to create a fresh resource type

    The scdsbuilder command starts the Solaris Cluster Agent Builder GUI, as shown in figure 4.7. In this example, data has already been specified for each province available to the user. A short code of SUNW is specified for the vendor name, and tstgds is specified for the application name. This data is then used to generate both the denomination of the package that Agent Builder creates for you and the denomination of the resource type that you will subsequently use.

    The information you provide in the other fields is used as follows:

  • The RT version enables you to specify a version number for this resource type. You can identify which version of the agent you are running when it is placed into production.
  • The working directory is used by Agent Builder as a working locality in which it can create your package and write other associated, intermediate files.
  • Your target application determines whether you select the scalable or failover option. If a particular instance of an application can sprint on multiple nodes at once without corrupting any of its data files, then you can select the scalable option. A proper specimen of such an application is a web server. For complete other applications, such as databases and file services, select the failover option.
  • The Network cognizant check box is used to determine whether any resource created using this resource type needs to gain the port_list property set. The port_list property is then used by the GDS service to provide a simple probe mechanism.
  • The source type option determines whether the resulting code uses the C programming language, ksh, or the GDS (see the section "SUNW.gds" in Chapter 2, "Oracle Solaris Cluster: Features and Architecture") to create the data service. To consume the C option, you must gain a C compiler installed on your system.
  • After you gain entered the data and clicked on the Next button, you are presented with the screen shown in figure 4.8.

    Figure 4.8

    Figure 4.8 Completing the resource type definition using scdsbuilder

    Integrating Your Application-Specific Logic

    You consume the fields in this second screen to provide the location of the programs (which can subsist compiled executables or scripts) and their associated arguments that will subsist used to start, stop, probe, and validate your data service when it is installed on the target cluster nodes. For each program, you can set a time limit on how long it can raise for the program to complete. If the program does not complete within the allocated time period, then the resource is placed into a failed state, such as STOP_FAILED.

    You are required to provide a value only for the start program. complete the other programs are optional. Any programs specified must exit with a recrudesce code of zero only when they gain successfully completed their work. If they fail to discharge their allotted task, they must recrudesce a value greater than 100. Values below that are used by the Solaris Cluster commands and gain specific meanings (see the intro(1CL) man page).

    The programs you allocate to the start and quit commands must recrudesce successfully only when your target application has actually completed the apposite operation. If the quit command leaves the application under its control running, or not completely stopped, but the quit command returns successfully, then the cluster framework erroneously determines that it is safe to start the resource group on another cluster node. In some instances, particularly when the application uses a global file system, this outcome could result in data corruption because the two instances of the application could write to their data files in an uncontrolled fashion.

    If no quit command is provided, the process tree that results from the start command is terminated using the destroy command.

    The validate command enables you to check that your application is correctly configured on complete the potential nodes on which it can run. Again, if the program determines that your application is misconfigured, the validate program must exit with a nonzero exit code.

    The capability to incorporate a probe command is one of the key benefits of using the Solaris Cluster framework. A probe command enables you to write a program that determines the health of your application. As an example, if you are writing a probe for a database, you could test whether it can execute basic SQL statements, such as creating or deleting a table, or adding or deleting a record. If you result not provide a probe script, then default methods are used instead.

    For non-network-aware applications, the process-monitoring command pmfadm (see the pmfadm(1M) man page) monitors the process tree spawned by your start command. Only if complete the processes gain failed will the cluster framework attempt to restart the service. Therefore, if your service consists of multiple processes and only one process fails, then pmfadm will not recognize this weakness unless it causes complete the other processes to fail as well. Consequently, if you necessity to monitor your application with a higher degree of granularity, you must provide a custom weakness probe.

    If the application is network-aware, then the default probe tries to open the port listed in the port_list property. Because this is a simple probe, it makes no attempt to retrieve any data. Even if the default probe successfully opens the ports, that does not necessarily argue overall application health.

    In the preceding example, you would install the package generated by scdsbuilder on complete your cluster nodes. You would then register the fresh resource type so that you could create fresh resources of this type. When the RGM is requested to create a resource, it calls the validate command: /usr/local/bin/my_validate -o some_param. If that command succeeds and you enable the resource, the RGM calls the /usr/local/bin/my_start -r foo-rs -g bar-rg command. In both cases, the initial arguments are fixed, but you can modify them subsequently using the clresource command.

    Resource type Registration File

    If you choose to write an agent from scratch using either the RMAPI or DSDL APIs, you must first relate the properties of your proposed resource type in a file known as the resource type registration (RTR) file. This file provides the RGM with details on which programs to summon and which variables are required to control the particular application.

    Example 4.18 shows an extract from the SUNW.LogicalHostname RTR file. As the specimen shows, complete the programs for this resource type are located in the directory defined by RT_BASEDIR. The RTR file also defines programs that will, among other tasks, start, stop, and probe (Monitor_start) the logical IP address that the resource plumbs. These addresses are, in turn, defined in the HostnameList property.

    The extension properties you define are complete application-specific. They could, for example, refer to the location of the software binaries, that is, the application home directory. If a property has a default value, then you can define it in the RTR file to reclaim your system administrator from having to override it each time he or she creates a resource of this type. Furthermore, you can situation limits on what values inescapable properties can raise and when they can subsist changed.

    Example 4.18. Extract from the SUNW.LogicalHostname RTR File

    The following text shows some of the key parts of the RTR file for the SUNW.LogicalHostname resource type:

    # # Copyright 1998-2008 Sun Microsystems, Inc. complete rights reserved. # consume is topic to license terms. # #ident "@(#)SUNW.LogicalHostname 1.20 08/05/20 SMI" # Registration information and Paramtable for HA Failover IPaddress # # NOTE: Keywords are case insensitive, i.e. users may consume any # capitalization style they wish # RESOURCE_TYPE ="LogicalHostname"; VENDOR_ID = SUNW; RT_DESCRIPTION = "Logical Hostname Resource Type"; SYSDEFINED_TYPE = LOGICAL_HOSTNAME; RT_VERSION ="3"; API_VERSION = 2; INIT_NODES = RG_PRIMARIES; RT_BASEDIR=/usr/cluster/lib/rgm/rt/hafoip; FAILOVER = TRUE; # To enable Global_zone_override GLOBAL_ZONE = TRUE; START = hafoip_start; STOP = hafoip_stop; PRENET_START = hafoip_prenet_start; VALIDATE = hafoip_validate; UPDATE = hafoip_update; MONITOR_START = hafoip_monitor_start; MONITOR_STOP = hafoip_monitor_stop; MONITOR_CHECK = hafoip_monitor_check; PKGLIST = SUNWscu; # # Upgrade directives # #$upgrade #$upgrade_from "1.0" anytime #$upgrade_from "2" anytime # The paramtable is a list of bracketed resource property declarations # that Come after the resource-type declarations # The property-name declaration must subsist the first attribute # after the open curly of a paramtable entry # # The Paramtable cannot hold TIMEOUT properties for methods # that aren't in the RT { PROPERTY = Start_timeout; MIN=360; DEFAULT=500; } . . . # HostnameList: List of hostnames managed by this resource. complete must be # on the same subnet. If necessity > 1 subnet with a RG, create as many # resources as there are subnets. { PROPERTY = HostnameList; EXTENSION; STRINGARRAY; TUNABLE = AT_CREATION; DESCRIPTION = "List of hostnames this resource manages"; } . . . Resource Management API

    The Resource Management API (RMAPI) is a set of low-level functions contained in the libscha.so library with both C and shell interfaces. complete the role names provided by this interface are prefixed with scha_. The shell interfaces are listed in section 1HA of the Solaris Cluster manual pages.

    The ksh scripts generated by the Agent Builder are built using these commands, so you can insert additional lines in this code where the comments indicate. However, for greater control over the logic imposed on your application you must write your application agent from scratch.

    Data Service progress Library

    The Data Service progress Library (DSDL) is a set of higher-level functions encapsulated in the libdsdev.so library that builds on the RMAPI functionality. This library can only subsist accessed using a C programming language interface. Consequently, it is potentially more time-consuming to write a complete application agent using this approach, although it does proffer the greatest even of performance and flexibility.

    If you used Agent Builder to create a resource type, you can customize it by inserting extra DSDL code where the comments indicate. Otherwise, you must write your agent from scratch.

    All the role names provided by the library are prefixed with scds_ and are documented in section 3HA of the Solaris Cluster manual pages. The NFS agent source code [NFSAgent] serves as a proper specimen of how these APIs are used. Using the nfs_svc_start.c source as a specific example, the library is initialized with scds_initialize(). Resource and resource group names are then retrieved using scds_get_resource_name() and scds_get_resource_group_name() calls, respectively. Finally, the status of the resource is set by the RMAPI scha_resource_setstatus() call. Most of the coding effort involved with using these interfaces is consumed by the logic that describes how the agent should behave in various failure scenarios. For example, how many times should the agent attempt to restart the service before giving up and potentially failing over? What should the agent result in response to a network failure?

    One edge of using the GDS is that complete the best practices for service deportment are already in the logic of the code that makes up the agent, saving you from re-creating that code.

    Useful Utilities for structure Custom Data Services

    The Solaris Cluster software comes with two programs that you will find very useful if you create your resource type from scratch: hatimerun (see the hatimerun(1M) man page) and pmfadm.

    hatimerun Command

    Throughout the Start, Stop, Monitor_start, and Validate methods of your resource type, you will necessity to sprint various programs to discharge the required logic steps. Because your goal is tall availability, you cannot wait for a program that might never respond or return, whether that program has gone into a loop or is unable to retrieve some famous data from the network, disk, or other program. Consequently, you must situation time constraints on the duration of the program's execution. This is the role of the hatimerun command. It enables you to execute a program under its control and set a limit on the time it can raise to respond. If the program in question fails to respond in a timely fashion, it is terminated by default.

    The hatimerun command also enables you to leave the program running asynchronously in the background, change the exit code returned after a timeout, or consume a particular signal to terminate your program.

    The most common usage of this command is in your probe commands or in the steps leading up to stopping or starting your application.

    pmfadm Command

    If you write a custom probe for your service, you choose what constitutes a hale service. The criteria might include application-specific checks to determine if the data it is delivering to potential clients is convincing or timely. If the application consists of multiple processes, you might want to check that each process is running, using the ps command. complete of these tests combine to give you the best assessment of your application's current health. However, your probe is scheduled to bear its checks only at regular intervals. Even though you can tune these checks to occur at shorter intervals, doing so results in a greater load on your system. Consequently, you must wait, on average, half the probe epoch before your probe detects a situation where your application has completely failed, signification that complete the processes gain exited. Once again, this does not aid much toward your goal of tall availability.

    The solution is to consume pmfadm, the process-monitoring facility command. When you start your application under pmfadm, it monitors complete the processes your application spawns to a even that you determine. By default, it monitors complete the application's child processes. If they complete exit, pmfadm immediately restarts your application for you on the condition that it has not already exceeded a preset number of restarts within a inescapable time interval.

    The most common usage of this command is in your start command to ensure that your key application processes are monitored and that complete failures are reacted to immediately.

    libschost.so Library

    Some applications store or bear consume of configuration information about the physical hostname of the server on which the application is running. Such applications will most likely fail when the application is placed in a resource group and moved between the nodes of a cluster. This failure occurs because calls to uname or gethostbyname bear different responses on the global zone of each cluster node. Oracle Application Server and the Oracle E-Business Suite are two examples of programs that risk such failures [LibHost].

    To overcome this limitation, you consume the LD_PRELOAD feature to enable the runtime linker to interpose the libschost.so.1 library in the dynamic linking process. The following specimen shows how this is done. You can consume the same construct within your resource Start or Monitor_start (probe) methods, as required.

    Example 4.19. How to consume the sclibhost.so.1 Library to Change the String Returned as the Hostname

    Use the uname command to array the current hostname.

    # uname -n phys-winter1

    Set the LD_PRELOAD_32, LD_PRELOAD_64 and SC_LHOSTNAME environment variables, and then rerun the uname command.

    # LD_PRELOAD_32=$LD_PRELOAD_32:/usr/cluster/lib/libschost.so.1 # LD_PRELOAD_64=$LD_PRELOAD_64:/usr/cluster/lib/64/libschost.so.1 # SC_LHOSTNAME=myhost # export SC_LHOSTNAME LD_PRELOAD_32 LD_PRELOAD_64 # uname -n myhost
