Postgres advanced Server is developed on the open source PostgreSQL database.
"The set of technologies they own now added will assist builders of customized purposes and packaged applications set up to DB2," pointed out Bernie Spang, director of strategy, analytics and data administration for IBM's software community.
For IBM, it be the primary time the enterprise has licensed expertise from a company of open source database utility, although EnterpriseDB founder Andy Astor referred to the utility embedded in DB2 is in accordance with proprietary code.
"here is now not an open supply play," Astor said. "every thing else they execute is open supply but that is among the methods they beget their funds, through promoting that compatibility technology both to vendors enjoy IBM, during this case, and to clients within the kind of Postgres Plus advanced Server."
EnterpriseDB elements to a brace of customers including FTD and Sony online entertainment which own migrated purposes developed for Oracle databases to Postgres Plus.

The licensing pact is the primary via EnterpriseDB, however Astor mentioned others are being negotiated.
IBM is hoping the stream will animate extra purchasers to migrate to its InfoSphere Warehouse 9.7 commercial enterprise version, a data-cleaning and commerce analytics platform in line with DB2 and technology IBM obtained from Cognos.

however that db2set has been round for a while, it seems that db2set isn't always neatly understood. according to IBM’s documentation, the IBM DB2 Profile Registry command (db2set) makes it feasible for for centralized manage of environmental variables. read on to study more...
one of the first troubleshooting alternatives I ever had with DB2 LUW worried db2set. That was with DB2 UDB 5.0 and became greater than a decade ago. Now I’m using DB2 9.7 and i’m nevertheless the disburse of db2set, so it definitely has some staying power. youngsters that db2set has been around for a while, in talking to other DBAs it appears that db2set isn't at bar no one times neatly understood.
in response to IBM’s documentation, the DB2 Profile Registry command (db2set) permits for centralized handle of environmental variables. There are diverse degrees of the Profile Registry.
From personal journey, I own create some enjoyable issues about db2set. once, when numerous DBAs own been attempting to disburse db2set at the equal time to supersede values for a similar illustration, my db2set -all output displayed incompatible values. This turned into conveniently mounted through conveniently choosing the all set of updates they wanted to beget and then having one adult execute the entire db2set commands. Of route, that was on a outdated free up of DB2 so it could possibly no longer be an issue with DB2 9.7.
I also discovered that DB2SYSTEM and DB2INSTDEF, which are set at the global level, can provide some advantageous counsel. just by means of searching on the DB2SYSTEM variable, i was as soon as able to investigate that a complete atmosphere had been deploy incorrectly the disburse of a file system copy method versus a measure and supported DB2 method. That one discovery saved me a lot of troubleshooting time.Are you and DB2SET Acquainted?
Most of us own had at least some exposure to db2set. suffer in intelligence this?$> db2set db2comm=tcpip
Or maybe in case your store uses SAP, you own used this particular combination registry variable which sets a lot of values by means of one profile registry update.$> db2set DB2_WORKLOAD=SAP however own you used this one? $> db2set -lr
If not, you should be would becould very well be lacking some advantageous advice. When the usage of the –lr option with db2set, that you can remark bar no one the supported registry variables that can be create for us with the product version for this setting up.
Who can supersede the DB2 profile registry? The reply is dependent upon the working device. On a UNIX platform, someone who holds SYSADM for the illustration can update registry values for that example. On home windows, when prolonged security is enabled, a SYSADM who belongs to the DB2ADMNS group can set and update the registry values.
When the usage of the DB2 Command Line to change a DB2 Profile variable value at the local or default instance level, the command is easily:db2set <variable>=<cost>
instance:db2set DB2COMM=tcpip db2stop db2start
(whereas the modern cost for DB2COMM is automatically saved in the profile registry, the exchange isn't utilized until a restart.)DB2SET Helps Itself
if you necessity greater assistance, it is convenient to fetch it. DB2SET provides a command line aid selection this is in fact valuable! simply adding a query heed to the conclusion of the db2set command returns a plenary pomp of tips.
$> db2set ?$> db2set ? DBI1300N db2set displays, units, or removes DB2 profile variables. db2set [variable=[price]] [-g|-i instance [db-partition-number]] [-all] [-null] [-r [instance] [node-number]] [-n DAS node[-u user[-p password]]] [-l|-lr] [-v] [-ul|-ur] [-?|-h]
The command alternate options are:-g access the global profile variables. -i Specifies the illustration profile to disburse instead of the existing or default. -n Specifies the faraway DB2 Administration Server node identify. -u Specifies the consumer identification to disburse for the Administration Server attachment. -ul entry the consumer profile variables -ur Refreshes consumer profile variables -p Specifies the password to beget disburse of for the admin server attachment. -r Resets the profile registry for the given illustration. The default/latest instance could be used if no one is provided. -l Lists bar no one illustration profiles. -lr Lists bar no one supported registry variables. -v Verbose mode. -? displays the command serve message. -h identical as -? alternative. -all displays bar no one occurrences of the autochthonous atmosphere variables as described in: * The ambiance, denoted by [e] * The person degree registry, denoted by using [u] * The node stage registry, denoted by means of [n] * The instance stage registry, denoted by passage of [i] and * The world even registry, denoted via [g] -null units the variables cost to null on the unique registry degree to evade looking up the cost within the subsequent registry even as defined within the variable value search order. Notes: * db2set with out a variable identify displays bar no one defined variables. * db2set <variable> displays <variable>'s value. * db2set <variable>= (nothing) deletes the <variable>. * db2set <variable>=<value> modifies the <variable>'s cost. * db2set <variable> -null sets <variable>'s cost to NULL. * db2set <variable> -all shows bar no one described <variable>'s values. * db2set -ur refreshes the latest user profile. * db2set <variable> -ul shows described <variables> at the consumer stage. * db2set -all shows bar no one defined variables in bar no one registry levels.
essentially the most generic approach to examine the set of values stored within the DB2 Profile Registry is to disburse the db2set –all command. perquisite here’s an illustration.db2set -all [e] DB2PATH=C:\software info\IBM\SQLLIB [i] DB2PROCESSORS=0,1 [i] DB2INSTPROF=C:\ProgramData\IBM\DB2\DB2COPY1 [g] DB2_COMPATIBILITY_VECTOR=MYS [g] DB2_EXTSECURITY=yes [g] DB2SYSTEM=LOCKSMITH [g] DB2INSTDEF=DB2 [g] DB2ADMINSERVER=DB2DAS00
offered you own the redress authority, you can additionally disburse the SYSIBMADM.REG_VARIABLES administrative view, which may also be queried to fetch the registry settings from bar no one database partitions. The outcome set could be diverse from what you could remark when the usage of the db2set -all. The mismatch can acquire region if a DB2 registry variable is configured the usage of the db2set command after the illustration has been started. REG_VARIABLES most effectual returns the values that own been in impact when the illustration become bar no one started.
right here’s an example:db2 "select CHAR(REG_VAR_NAME,35) AS REGVAR, CHAR(REG_VAR_VALUE,35) AS value, degree FROM table(REG_LIST_VARIABLES()) AS REG ORDER by three,1" REGVAR value level ------------------------- ----------------------------------- ----- DB2PATH C:\application info\IBM\SQLLIB E DB2ADMINSERVER DB2DAS00 G DB2INSTDEF DB2 G DB2SYSTEM LOCKSMITH G DB2_COMPATIBILITY_VECTOR MYS G DB2_EXTSECURITY sure G DB2INSTPROF C:\ProgramData\IBM\DB2\DB2COPY1 I DB2PROCESSORS 0,1 I considering about the Future
With each modern version of DB2, the profile registry alternatives are discipline to alternate. So earlier than upgrading, or performing a brand modern installation, one investigation I undertake is to be taught concerning the a lot of alternatives for db2set as they keep to that selected product degree. The IBM DB2 information heart is at bar no one times my useful resource for that. For DB2 9.7, you could ascertain assistance for the db2set profile registry alternatives dawn at http://publib.boulder.ibm.com/infocenter/db2luw/v9r7/index.jsp?theme=/com.ibm.db2.luw.admin.regvars.doc/doc/c0004934.html. Drilling down from that hyperlink will give you bar no one of the details.final recommendations
on occasion there are some very valuable Profile Registry variables that can also be set to extend performance or serve DBAs unravel application considerations. It’s enjoy opening a shock reward, you are watchful of it might be whatever thing respectable, however you’re just now not bound how advantageous it could be except you look. once you unwrap the information about db2set, you are going to acquire note the passage to disburse that capabilities as a present in your DB2 ambiance.

This one started (as many do) with a convene for serve from one of their DB2 customers. bar no one of the rows had been deleted from a censorious table in a pre-production environment. The junior DBA had bravely admitted to accidentally connecting to the wrong system to clear down the table, but couldn't understand why he'd been able to delete the rows as he shouldn't own had the authority to execute so.
In bar no one such circumstances, the priority is always to fetch the data back and the developers working again. This was quickly accomplished with a measure recovery using a recent backup and no problems were encountered. They then turned their attention to the job of figuring out how the junior DBA had been able to delete the data in the first place.
After much investigation, they discovered the following:
Needless to say, the FED_NOAUTH parameter was rapidly set back to NO and proper authentication checking was reinstated.
Many of us disburse a lot of time tuning databases and applications, but how often execute they reflect about their own performance? Time and again, they remark examples of DBAs and champion staff that are taking the long passage round and using more time than necessary to discharge routine tasks. One particular aspect of this is the disburse of the command line versus a GUI such as the DB2 Control Center.
I know plenty of people who are passionate supporters of the GUI, and indeed it can be a very advantageous passage to quickly accomplish one-off activities such as an ad-hoc reorg. However, there are plenty of situations where disburse of the command line (or better still, DB2 commands embedded in a simple script) will beget much more sense. The job is then easily repeatable, actions and their results can be recorded (by redirecting the output to a text file), and a script is a lot easier to hand over to a colleague than pages of instructions and GUI screenshots!
A common instance is the routine process of promoting database objects between development, test and production environments. A advantageous script can accomplish that job in a fraction of the time needed to execute the very thing from the GUI, and utilities such as db2look can be used to compare database structures to ensure consistency.
Many of us are working in environments where the SQL presented to DB2 is not written directly by a human being, but generated automatically by a tool. Common examples involve Java frameworks, 3GLs and commerce intelligence tools such as Cognos in this example.
In this example, the customer reported a long elapsed time for a Cognos-generated query (over 30 minutes) running against a DB2 9.5 database, with the query consistently failing due to the DB2 temp space being exceeded. The users repeatedly increased the temp space and re-tried the query, but with exactly the very result each time. In desperation they even ran the DB2 Index Advisor and created additional indexes, but temp space noiseless blew before the query finished.
A champion incident was opened, and analysis using a third-party query monitoring implement showed a very towering query execution cost. Further examination of the actual SQL being generated by Cognos showed a Cartesian join of two tables, each with more than 25M rows in, with the modern indexes not being used at all. Going back to the Cognos definitions showed a key database relationship had not been defined to Cognos, so it had to filter vast amounts of data locally.
The solution was simply to re-work the Cognos report definitions to add the missing database relationships. This caused Cognos to generate redress join predicates and the reports ran to successful completion in under 2 minutes. The developers were also educated to search for at both the Cognos and generated "native" SQL in the future.
This particular issue happened in a development environment where DB2 for LUW 9.7 was the back-end database, but it could really own been any other RDBMS. A highly-skilled offshore team was developing a modern application, with a local system administration team looking after the OS support.
Triton was originally contacted as a one-off exercise, as the developers were complaining about consistently needy query performance and asking to skid to another RDBMS as DB2 was clearly not up to the job. They create a surprisingly common situation: the team of developers, highly skilled in SQL and able to formulate complicated queries, were completely focused on the application code and no one was looking after the data. Consequently, there was no backup regime in place, no RUNSTATS or other housekeeping, and the only indexes were primary ones created when the database was first designed. Not surprising then that the query performance had been so needy — no one of the tables had ever had stats collected.
Further questioning revealed that the developers had no DB2-specific erudition whatsoever, and no want to learn. As far as they were concerned, the database was a black box that they could toss SQL at and fetch data back.
We quickly implemented a basic set of automated housekeeping procedures that resolved the performance issues and made the developers happy. However, in the process they uncovered a lot of data quality issues (such as developers coding inefficient SQL to fetch around duplicate data that shouldn't exist). A more formal design review of the database was conducted, and they were asked to provide an ongoing remote DBA service to avoid the very issues arising in the future.
This is a Great instance of how "finger trouble" can antecedent red faces and application outage. The Senior DBA for a major public services application took his annual vacation, leaving a recently-trained Junior DBA in charge. Responding to a request to clear down a development database, the Junior DBA fired up his telnet session, dropped and re-created the material database and congratulated himself on a job well done ... until the phones started ringing with users complaining that they couldn't disburse the production application. The DBA had accidentally dropped a censorious production database, thinking that he was connected to the UAT system.
To his credit, the DBA was quick to own up to the mistake and Triton was called in to assist with the recovery. This was conducted without further drama, but the best section of a commerce day had been lost by the time everything was back to normal.
We received a frantic convene one evening from a customer asking for immediate help. DB2 had "hung" and no activity could be performed on the production database. As the OLTP system had a 24x7 online SLA, it was not surprising that the senior management was waiting when they arrived at the customer site. Upon investigation, it became manifest that DB2 was looking for an lively transaction log file that had gone "missing" and was nowhere to be found.
After investigation, the sage started to become clearer. In a desperate attempt to create some space on the production database server, a junior sysadm had stumbled upon the DB2 transaction log directory (which in this case housed both the lively and archived logs) and thought, "Hmm, this directory could execute with some clean-up." Using his judgment of the age of the files, he deleted some of them. He gained space but unfortunately lost an lively transaction log file in the process.
Despite their recommendation that a restore from a previous backup was the only solution to their problem, the local Oracle DBA with some DB2 erudition tried various methods to "trick" DB2, enjoy creating a dummy log file with the very name as the missing one, not knowing that the DB2 transaction log files own header information within them. After a lot of delay, it was finally agreed to carry out a restore from the most recent backup. This proved rather of a challenge since no backups were stored on disk. So, the redress tape had to be create and mounted. The restore and subsequent rollforward to a consistent point in time did successfully acquire region and sighs of relief could be heard in the early morning hours. Even though some hours of commerce had been lost, jobs had been saved! And yes, even the junior sysadm was allowed to stay on since he owned up to his mistake...
Here's a nightmare champion scenario: a broken database on an unsupported version of DB2, with no backups or log files to recoup the database.
An erroneous script had deleted a few transaction log files that had a 'last changed' date of more than 45 days. The very script had caused other errors and a database restart was required, but the database did not start. The database was looking for an obsolete log file, which had just been deleted by the script. As the policy was to retain the backups and archive logs for 30 days, this log file was deleted from the archive logs too.
The database was tiny — less than 50GB. Nevertheless, it was a very necessary one, with a number of web facing apps relying on it for necessary features. To beget matters worse, the version of DB2 in disburse had passed its "End of Service" date, so DB2 champion was not willing to investigate (though they were blissful to guide).
When they got involved a few hours after the incident, panic had set in. Based on information available (saved snapshots and db2diag.log file), they were able to conclude that there was a transaction which started in the log file the database was looking for. This transaction was never completed. The rate of change of data was so small, the configured log numbers could proceed on for more than 45 days.
The options available were to extract the data from the latest backup image (using tools enjoy towering Performance Unload) or extract the data from the damaged database (using db2dart). The latter option was chosen as this would allow us to recoup the most recent data.
Without further delay, they ran db2dart on the database to check for any errors and to fetch the Tablespaceid, Tableid and the total number of pages allocated to each table. They were then able to disburse the information to build the db2dart command with the DDEL option to extract the data in delimited format. db2dart with the DDEL option is interactive (i.e., when the command is run, it prompts for the tablesapce id, tableid and the page ambit to extract the data). This meant that the extract could not be scripted but had to be done manually for each of the 300+ tables.
Once that mind-numbing job was complete, they created a modern database with the DDL that was available (thankfully, they had a db2look output from the production database less than a week before the incident). Finally, they loaded the extracted data to the modern database and ran runstats on the table and indexes.
After a few hiccups and 15 hrs of db2dart, import/load, runstats and data fixes, the database was available for the application. The database was down for more than 20 hours, but it was back in once piece with nearly no data loss. Quite an achievement under the circumstances!
We often own to question customers for the DB2 diagnostic log file (db2diag.log), only to be told "it's too large to send" or "it's taking too long to open." This is because the DB2 diagnostic files own been appended only since time immemorial, their growth only restricted by the maximum space available in the file system they reside in. The only passage to curb this growth would be to rename the files, which would then constrain the creation of modern ones. Scripts had to be written to automate this process and to delete obsolete files after a inescapable period. Many customers didn't own these processes in place.
With the advent of DB2 9.7, bar no one this is now history! The modern DIAGSIZE database manager parameter allows a DBA to control the maximum sizes of the DB2 diagnostic log and administration notification log files. When this parameter is set to a non-zero value (which is the default pre-DB2 9.7 behaviour), a chain of 10 rotating diagnostic log files and rotating administration notification log files (only on UNIX and Linux) are used. It is also smart enough to spotless up obsolete log files from the diagnostic log directory. When the 10th file is full, the oldest file is deleted, and a modern file is created.
The customer was using HADR to a remote server for resilience, running in ASYNC mode to minimize the performance impact. No cluster software was used for monitoring/failover, but the HADR condition was being monitored on a regular basis using a shell script.
On the primary site, a few disks failed, which caused some of the tablespaces to be allocate in "Rollforward Pending" State. Transactions accessing data in these tablespaces failed but the others were successful. The terminal speed of the HADR condition monitoring script indicated a Peer State, and therefore it was decided to issue a TAKEOVER command on the DR Site to switch roles. When the application started, some transactions failed with the very oversight as on the primary site — not good!
A list tablespaces command showed a number of tables in "Rollforward Pending" state. To fetch out of the pending state, the ROLLFORWARD command was issued with the list of affected tablespaces. The rollforward was trying a retrieve a log, which was a few thousand logs older than the current one. Not surprisingly, this log was not available in the archive. After a few more tries, the ROLLFORWARD option was given up and the database was restored from the latest backup image and the application started.
So what happened? They went through the db2diag.log and the notification logs. They could remark that there were physical errors reported in some of the tablespaces on the DR site (HADR Standby) around 100 days prior to the incident. This was reported in the db2diag.log, and the affected tablespaces were "excluded from the rollforward set." Based on other entries in the db2diag file, they were able to authenticate that the log file requested for rollforward on the DR site was used at the time the physical errors occurred there. HADR continued to apply logs for the other tablespaces and was reporting to be in "Peer" State. In reality, some of the tablespaces were being ignored.
I'll round off my top ten with one of the most basic issues they encounter, but unfortunately one of the most common. It's astonishing how many DB2 sites don't own basic procedures in region for contacting IBM champion in the event of a sedate DB2 issue.
If you're having a sedate production problem and you necessity IBM's assistance, every minute is vital. That is not the time to be scrabbling around to try to dig out customer numbers and URLs for the IBM champion Portal. They own even seen situations where the IBM champion site is blocked by the organisation's web browsing policy!
IBM is generally blissful for you to open "test" PMRs to prove that the process works and ensure you can contact them quickly and efficiently if the necessity arises. Finally, don't forget that it's feasible for your IBM commerce colleague to open and manage your PMRs for you — they execute this for many of their customers as a matter of course.
I hope you'll be able to learn something from at least some of these scenarios, and acquire steps to avoid similar situations happening in your environment.
