I've begun to circulate my company's building and check databases to an Oracle Multitenant structure. Multitenant...
is never new, having debuted in 2013 with the initial liberate of Oracle Database 12c, edition 22.214.171.124. So, why am I poignant to it now?
below is a listing of motives, starting from end-of-existence expertise concerns to easier administration and the skill to deploy more databases on their latest techniques. study on to peer if your company should reliance becoming a member of mine in adopting Oracle Multitenant, which -- for those not already within the recognize -- enables you to position several pluggable databases privilege into a lone container database. feel of Multitenant as virtualization moved to the database level.
Oracle has deprecated the non-Multitenant structure in 12c. it is right! You can exist pressured to movement to an Oracle Multitenant architecture at some constituent sooner or later, even though there isn't any widespread arrangement for a edition of Oracle Database during which non-Multitenant configurations will quit to exist. even if you don't want the multi-tenant capabilities now, that you could dawn getting used to the newfangled system with the aid of inserting one pluggable database into a container -- what Oracle calls a single-tenant configuration.
That doesn't intimate you should pay for the added-charge know-how -- in case you only absorb one pluggable database, Oracle Multitenant is free. but if you carry out want to Run a brace of pluggable database in a replete multi-tenant architecture, you'll deserve to pay the further licensing charges.
Our VMware atmosphere is approaching end-of-lifestyles. They at present Run their construction and peer at various databases in VMware, licensing Oracle Database on the processors in their Oracle-simplest VMware ESX cluster. besides the fact that children, we're operating ESXi 5.5, for you to lose ordinary support in September 2018. They can not ameliorate to the newer ESXi 6.0 or above with out being pressured with the aid of Oracle License administration features to license Oracle Database on outright processors in the entire ESX clusters in their commercial enterprise. Oracle's position is that it exist too handy to live-migrate their virtual machines (VMs) to other ESX clusters, so that they absorb to outright exist licensed.
whereas running Oracle on VMware ESX has been extraordinary for us, it's transparent that they can not proceed to accomplish that for the long term. My enterprise needs to locate a different retort and noiseless continue to exist agile in their database infrastructure. operating Oracle Multitenant on actual servers can allow us to purge VMWare from their Oracle infrastructure, whereas not handiest keeping, however besides improving their agility.
Database administration gets less demanding. An Oracle Multitenant structure forces a astronomical exchange in how database administrators (DBAs) strategy their jobs. They should entrap into account no matter if particular administrative initiatives should exist carried out at the container or pluggable database stage. however, once DBAs overcome that researching curve, they'll learn their time spent administering a database is reduced.
after I started with my business, they had a dozen nonproduction databases. In seven years, that import has grown to more than 30 databases. however initiatives at the container database stage handiest should exist carried out as soon as, no depend what number of pluggable databases I have. And initiatives at the pluggable database stage are without rigor scripted to loop through the entire databases for execution.
we can add extra databases. My company has always struggled with the confined variety of databases at their disposal. As I pointed out, I've considered the variety of nonproduction databases grow from 12 to greater than 30. Their management would really dote for us to absorb much more databases for their software developers, however we're limited by using resource concerns at the VMware hypervisor host.
so as to spin up an extra VM, we'd necessity greater memory -- or not it's the quantity of attainable RAM that looks to exist their bottleneck. With their Oracle Multitenant structure, they are able to Get rid of the overhead of reminiscence and other apparatus resources from each VM. This enables us to install even more databases than before with the same actual hardware.
Clones can besides exist created extra quickly. they now absorb scripts in belt to create a database clone. They utilize disk-primarily based snapshots and clone their multi-terabyte database on the disk storage. They then mount those clone volumes to a VM and open the database.
With their present setup, they can create several clones of their production databases in their digital machines. These clones are used to create test databases and many construction databases that are copies of production.
Oracle Multitenant can clone a pluggable database, but additionally has the capacity to operate a image clone. a regular clone duplicates outright the records information in a database. This works first-rate for tiny databases, however their basic creation database is over 15 TB in measurement.
a regular multi-tenant clone would require duplication of the statistics information, however a picture clone completes in under a minute without duplicating them. Any changes to the clone influence in newfangled blocks on disk; the long-established pluggable database makes utilize of the classic blocks, whereas the clone receives a copy of the exchange screen only. This permits for very speedy cloning, whereas besides reducing the disk house requirements.

This sample chapter from e-Business for the Oracle DBA covers capacity planning, using StatsPack for capacity planning purposes, architectural issues and components of an e-Business, and design issues for e-Businesses.This chapter is from the bespeak Capacity Planning, Architecture, and Design Issues Essentials
Proper capacity planning can minimize performance problems in the system after it is implemented.
Capacity planning for an e-Business is an knack rather than a science because its requirements change outright the time.
Oracle8i (release 8.1.6) and higher provide a mechanism called the STATSPACK utility for historical data collection and the capability to translate the data into reports that can interpret database usage trends.
One key characteristic of a successful e-Business is its capability and willingness to change quickly according to market needs. An even better characteristic is its capability to forecast the direction in which the market might shift in the future so that it can prepare in foster to meet the newfangled demands.
The e-Business architecture is better than a straight client/server architecture because the client doesn't wait connected to the database, the application server stays connected only for the time required to design a request and receive the results back from the database server, network traffic is reduced, idle processes carry out not consume resources, and response time is improved.
When you start to inch your systems to an e-Business, it can abet to start tiny and identify a tiny project that can quickly design the transition and at the same time provide tall impact and revert on investment (ROI). When this transition is successful, you can build on the tang and feedback from this venture.
An e-Business needs to absorb a forward-looking application architecture that deals with the following captious requirements:
Integration of intra-business processes
Innovative methods for adding value
Customer- and solution-oriented procedure
Plan for growth and change
In this chapter, they will carry out the following:
Learn how to discharge capacity planning
Learn how to utilize StatsPack for capacity planning purposes
Examine architectural issues for an e-Business
Examine the architectural components
Look at design issues for e-Businesses
Capacity planning is allotment of the planning phase. This very distinguished process is completed with the end of minimizing performance problems with the system after it is implemented. In this sense, capacity planning involves analyzing the same kinds of issues that you would anatomize when tuning the system:
How should you select the system components to use?
What ilk of architecture is suitable?
What values should exist set for the various parameters?
What are the characteristics of the applications?
What are the characteristics of the system?
What business rules are to exist implemented?
How much can exist forecasted or predicted about the system usage?
What are the system requirements in terms of availability? Scalability? Security? Performance?
Good capacity planning provides a cushion for sudden bursts in load and can tolerate some application inefficiencies.
Capacity planning for an e-Business is an knack rather than a science because its requirements change outright the time. Its characteristics besides change outright the time and are difficult to predict. To understand the capacity planning issues with an e-Business such as DOeBIZ.com, you absorb to understand that it is very difficult in such an environment to absorb a satisfactory architecture that meets outright the requirements well. You should arrangement for feasible extra growth and build a system that has more capacity than current and predicted future needs.Capacity Planning Questions
Several distinguished questions necessity to exist addressed as allotment of the capacity planning process:
Generally, scalability is determined in terms of the performance increase relative to additional system components; for example, if one CPU gives a performance of x and adding an extra CPU gives a performance of 1.4x, the scalability is 1.4. This increase is not usually linear because of the overhead associated with coordinating the activity of the additional components. beneficial capacity planning requires a beneficial understanding of future needs. If you improperly forecast future needs, you might exist able to fullfil your immediate system needs, but fixing problems due to unforeseen increases or changes of needs would require a lot of effort.
What are the availability requirements? Availability requirements are generally specified as the percentage of time that your system has to exist up. Transaction processing e-Commerce sites usually absorb very tall availability requirements. The Internet itself has a reliable built-in capability to route around problems; therefore, when you're looking at tall availability solutions, you should peer at these elements of your own system:
Disk drives—Consider using a Redundant Array of Inexpensive Disks (RAID) configuration.
Web server hardware—PCs are cheap but not very reliable, whereas mainframes are extremely reliable but very expensive. Therefore, you could utilize workstations as a compromise for the Web server hardware.
Operating system—Compared to Windows and Macintosh, UNIX systems are much more stable and are better suited for tall availability requirements. You might besides respect a high-availability OS such as Solaris HA.
Uninterruptible power supply (UPS)—Using a UPS is a necessity.
Clustering solution—You should seriously respect using a UNIX- or NT-based clustering solution.
High availability requirements impose quick reaction by an iDBA. Therefore, it is very valuable to absorb an architecture in situation that supports automatic notification to an iDBA when performance falls below a inevitable threshold or when other captious events occur.
What are the budgetary constraints? Money is always an distinguished issue, and you necessity to ensure that the chosen architecture can provide a tall benefit-per-cost ratio. You should besides respect the budget for ongoing maintenance and upgrades of the architecture as well as the cost for administration and performance tuning.
Beware of Bottlenecks
When you add extra components to increase capacity, entrap care to ensure that you are not introducing a bottleneck somewhere by virtue of this system change.Oracle Database Trend Analysis Using STATSPACK
Proper designing and capacity planning (and later, database tuning) will profit tremendously if some trend analysis is available for the database usage. Oracle8i (release 8.1.6) and higher provides a mechanism called the STATSPACK utility for historical data collection and the capability to translate the data into reports that can interpret the database usage trend. Even though Oracle introduces STATSPACK with Oracle 8.1.6, a patch available from Oracle Corporation allows you to utilize STATSPACK with any Oracle8 database.
The STATSPACK utility is a set of scripts that Run a special version of the Oracle BSTAT/ESTAT utilities. Unlike BSTAT/ESTAT, STATSPACK captures performance data and stores it in special Oracle tables with names that absorb the prefix STATS$. Each STATS$ table is owned by the PERFSTAT user. Note that you can utilize the regular SQL*Plus portray command to determine the columns in the STATS$ table.
DBAs commonly utilize trend analysis to understand the deportment of the database at various times. This ilk of analysis besides helps in identifying patterns of deportment in terms of database usage. Oracle Enterprise Manager (OEM) provides a capacity planning tool as well, but STATSPACK provides a big number of statistics that can exist used to generate different types of trend reports. Here are some useful metrics:
Data buffer hit ratio—This metric gives an belief of the effectiveness of the database buffer cache and the setting of the db_block_buffers parameter.
Physical disk reads and physical disk writes—These metrics give a beneficial belief about the I/O activity in the system.
I/O waits—This metric can exist used to determine I/O contention problems and can bespeak whether the physical design of the database is good.
Sorts—This metric is an indication of the effectiveness of sort activity.
Buffer industrious waits—This metric is an indication of freelist contention and can besides bespeak concurrent UPDATE or INSERT activity on the same object.
After STATSPACK captures the various performance statistics, you can generate various trend reports using the data gathered. These trend reports would provide signatures for various database metrics. For example, you might celebrate that on Monday mornings between 8 a.m. and 9 a.m., the I/O activity is extraordinarily high. This lore can abet in taking the proper actions. In order to forecast the database growth trend properly, you must archive and anatomize the data that is collected by any tool such as STATSPACK. The script in Listing 3.1 shows how to plot the middling I/O occurring by hour of the day.Listing 3.1 Determining the middling I/O by Hour of the Day Set pages 9999; Column phyreads format 999,999,999 Column phywrites format 999,999,999 Select To_char(snap_time, 'HH24'), Avg(physical_reads) phyreads, Avg(physical_writes) phywrites From Perfstat.stats$buffer_pool_statistics bp, Perfstat.stats$snapshot sn, Where Bp.snap_id = sn.snap_id Group by To_char(snap_time, 'HH24');

With the recent changes to Oracle JDK distribution and support, there has been considerable doubt over the future of Java, over the software lifecycles, and over vendor-provided support. This document summarises the changes Oracle is making, and the options available for users of Java SE.
WHAT carry out THEY weigh in BY FREE?
In a nutshell, the word “free” has two several meanings in software:
“Free as in beer” refers to the cost (i.e. money) of the software (aka $free).
“Free as in speech” refers to what you are allowed to carry out with the software.
As explained in the Shorter Version, you can noiseless Get Java SE binaries “free as in beer” from Oracle and other Java SE / OpenJDK providers.
Although there are proprietary and/or restricted usage implementations of Java SE out there (Azul’s Zing, Oracle’s JDK etc), for a vast majority of users there is always the option of using an OpenJDK binary, which is “free as in speech” as it is GPLv2+CE licensed.
These changes absorb happened within a short time frame creating a consummate storm of doubt as day to day developers, who don’t result the industry news closely, Get caught up. This leads to factually incorrect posts like:
Which are luckily counterbalanced by more accurate posts such as:
This article will cover the main areas of concern and what’s being done about those concerns by the ecosystem. By the halt of this post, you should exist reassured that Java SE is noiseless being well looked after and that it has a future stronger than ever!The newfangled Six Month Release Cadence and LTS
Java SE now has a feature release every six months, using a newfangled versioning scheme which was previously announced in 2017. Thanks to improvements in JCP processes, OpenJDK committers can now introduce spec changing features (such as var in Java SE 10) on the six-month cadence.
WHAT DOES LTS weigh in WITH REGARDS TO JAVA / OPENJDK?
Long Term support (LTS) in OpenJDK is really just an understanding between the various contributors (led by Oracle) that the code line for Java SE 11 / 17 / 23 etc will exist maintained for a longer period of time than six months.
Oracle will lead the first six months of an OpenJDK LTS code line, providing updates and producing Oracle OpenJDK builds, but will then afterward only provide updates for Oracle JDK, under a paid support plan.
However, Oracle will drudgery with other OpenJDK vendors to hand over the OpenJDK LTS code line and allow them to continue working on it together to provide updates. Each vendor then has the altenative of providing updates and/or paid support for the binaries they produce.
NOTE: This does weigh in that Oracle’s JDK could disagree from the OpenJDK based binaries produced by other providers (this has always been the case). That said, as long as the binaries pass the TCK, you’re assured that those binaries are compatible with the Java SE standard.
Understanding the newfangled versioning scheme (including what LTS means) and how newfangled features are introduced impacts how each version is maintained. By maintenance, they weigh in the provision of update releases with security patches and distinguished bug fixes.
UPDATES vs SUPPORT
Updates mention to the code patches that absorb gone into OpenJDK and Oracle JDK. These absorb typically gone in for free, until vendors select that there’s an halt of Public Updates process.
Support means a commitment to fix bugs and it requires staff to retort users’ problems, and that costs money. To exist transparent there has never been free support for Oracle JDK or OpenJDK.
Up to and including OpenJDK 8 / Oracle JDK 8, updates were provided by Oracle and other OpenJDK committers within a “feature release”. Feature releases, such as 8u91, 8u111 and 8u131 (on a six-month cadence) were superseded by each subsequent feature release. For example, once 8u111 was released, you would not Get updates on 8u91.
Starting with OpenJDK 9 / Oracle JDK 9, the newfangled six-monthly release cycle came into consequence and updates now occur between “feature releases”, i.e. Similar to 8u91 -> 8u111, once 12 is released, you will not Get updates to 11 by Oracle (However, other OpenJDK committers, likely lead by Red Hat, will provide these).Oracle Updates Plan
Until Java 8, Oracle provided updates for the Oracle JDK for a 3+ year lifecycle, and usage was permitted in personal as well as commercial settings. The updates provided no support, and support required the purchase of express licenses from Oracle. Paid support besides entailed longer update cycles.
Starting with Java 9, Oracle has moved to a faster cadence for Oracle JDK and besides started producing Oracle OpenJDK builds. Updates will generally exist provided for 6 months before they are stopped upon release of the next version. If updates/support are required for a longer duration, or for production use, then it must exist purchased from Oracle (i.e. You must exist on Oracle JDK). Periodically, releases will exist marked “LTS”. These releases will exist supported by Oracle through their benchmark support licenses for an extended period. As of privilege now, the Oracle update arrangement for Oracle OpenJDK builds, with updates, is as follows:Oracle Updates Plan
The belief here is simple. As has been the model of Java SE going pass back to the Sun era, Oracle focuses on newfangled innovations and poignant Java SE forward. Organizations who wish to remain on legacy versions can carry out so via commercial support offerings. Of course, for some Java SE users and progress shops, such rapid upgrade is not feasible.OpenJDK Updates Plan
The OpenJDK community works on a free, open-source implementation of the Java SE standard. Oracle contributes heavily to the project, and it is the basis for both Oracle OpenJDK builds and Oracle JDK. OpenJDK 11+ is interchangeable with Oracle JDK for applications that adhere to the Java SE benchmark and are using a build that has been tested against the TCK. Oracle will continue to contribute to OpenJDK while they provide updates for the corresponding Oracle OpenJDK build version. Once that version is superseded, Oracle will cease contributing to that version and start updating the next one.
Oracle has been highly receptive to the belief of community maintenance (for OpenJDK 6 and 7) and will continue to support handover of OpenJDK to the community to a qualified volunteering entity once they absorb moved on to working on the next version. Red Hat stepped in to globally lead (and provide regular updates to) OpenJDK 6 and OpenJDK 7 projects after Oracle ended updates for them. After Red Hat stopped updating OpenJDK 6, Azul Systems stepped in to lead the project and they continue to provide updates to this day.
Red Hat intends to apply for the leadership of OpenJDK 8 after Oracle stops updating it in January 2019. It is distinguished to note that while Red Hat leads the OpenJDK 6 and 7 projects, they are not the sole contributors. Other vendors provide patches and fixes from time to time as well. With OpenJDK 8, there will exist more contribution than ever before from non-Red Hat companies, such as Amazon, Azul, IBM, and others.
For consistency, the OpenJDK update cycle will exist extended for the same versions that are deemed LTS for Oracle JDK. As of privilege now, OpenJDK support cycle is as follows:
NOTE: These times are topic to change and different providers outright absorb slightly different timeline commitments. Therefore they utilize the term “At Least”.OpenJDK Updates Plan Java SE / OpenJDK Providers
There are now a big number of Java SE / OpenJDK providers who provide either updates and/or paid support options. The following sections provide a lot of detail, if you prefer a shorter read then Stephen Colebourne’s Java SE 11 Options post gives a summary.
UPDATES vs SUPPORT
Updates mention to the code patches that absorb gone into OpenJDK and Oracle JDK. These absorb typically gone in for free, until vendors select that there’s an halt of Public Updates.
Support means a commitment to fix bugs and it requires staff to retort users’ problems, and that costs money. To exist transparent there has never been free support for Oracle JDK or OpenJDK.Why Would I select Commercial Support?
If you necessity a fix in a timely manner, someone to respond to your user requests, or if you want the reassurance that the binary you utilize is being backed by a vendor, then Azul, IBM, Red Hat, Oracle et al. outright proffer choices.
A PHILOSOPHICAL POINT ON PAYING FOR OPEN SOURCE SOFTWARE
The industry at big has settled firmly on Open Source Software as the pass forward. Because of its “Free as in speech” nature, OSS licenses allow folks to modify and reconcile other people’s software without fright of punitive action.
Many folks besides relish the “Free as in beer” nature of much OSS software, but this comes at a powerful cost to the authors! Software developers, dote anyone else, necessity to do a roof over their heads and food on their table. Vendors dote Oracle pour vast amounts of money into Java SE (think 10s of $ Millions per year at the very least) and they carry out necessity to virtually pay for that cost.
So although you’re certainly not obliged to Go with a paid support option with one of the vendors, sometimes it’s worth thinking about how you, the halt users, can support the Java SE ecosystem to ensure it has a long lasting future!Provider Summary Build yourself from Source
Build from Source [OpenJDK, no commercial support, necessity to self-build]:Free Binary Distributions
Free Builds for Linux, Windows, Mac, etc. [OpenJDK, no commercial support]:Commercially Supported Distributions
Commercially supported [all Java SE compliant]:
Azul Systems [OpenJDK base]:
IBM [OpenJDK groundwork classes + Eclipse OpenJ9 VM]:
Oracle JDK [OpenJDK base]:
Red Hat [OpenJDK base]:Linux Distros
The various Linux distros will continue to provide OpenJDK for their respective distributions including but not limited to Debian, Ubuntu, CentOS, Fedora, Mint, Alpine et al.
AdoptOpenJDK provides OpenJDK binary distributions (HotSpot and Eclipse OpenJ9) for a very wide orbit of platforms (Linux, Mac, Windows 32/64, Arm 32/64, z/OS, Solaris, AIX, PPC, s390 and more).Support Options
Azul provides OpenJDK binaries (Zulu) as well as a specialised Java platform (Zing).Support Options
Azul offers an option for outright companies that carry out not want to skip outright Java SE versions between LTS releases but cannot switch to the newest version every 6 months. Next, to the support for outright LTS releases, where Azul provides 1 more year of support than Oracle, Azul offers support for so-called Medium Term support (MTS) releases for their Zulu JDK. Here you can buy commercial support for every second Java SE version regardless of if it is LTS or not. The support duration of these versions is different. Azul tries to provide a beneficial time orbit to prepare a migration to the next version and defines 3 different durations for support of Java SE versions.
Unlike Oracle, the commercial support of Zulu is not defined per CPU but based on the number of systems. A system is defined as a physical or virtual server. The only divergence between benchmark and premium support is the availability of the support. By buying premium support you can convene Azul 24x7.Important Links IBM
IBM provides indigenous JDK bundles for AIX, Linux (on x86, Power, zSystems), z/OS and IBM i. IBM offers the IBM SDK for Java SE versions for utilize with IBM products or platforms and for developer utilize from developerWorks. IBM besides provides OpenJDK (with Eclipse OpenJ9) binaries built and tested at AdoptOpenJDK.Support Options
For Java SE 7 and 8, IBM noiseless provides security updates and bug fixes. The IBM support lifecycle will continue to exist updated. Based on the newfangled Java SE release schedule IBM has announced that the non-LTS releases will exist available as OpenJDK with OpenJ9 binaries from AdoptOpenJDK.Important Links Oracle
Oracle now produces two JDK binaries: the traditional Oracle JDK and an Oracle OpenJDK build.Support Options
In June 2018, Oracle replaced its legacy “Java SE Advanced” perpetual license support product with a Subscription based offering that includes license and support. One of them targets Java SE on the desktop and the other one Java SE on the server, cloud, and Java SE in general. If you carry out not utilize Java SE on the desktop the “Java SE Subscription” will exist the privilege support model for you. If you utilize Java SE on the desktop for client applications the “Java SE Desktop Subscription” product is available. If your software uses a Java SE server and Java SE based clients you can subscribe to both offerings.
Commercial support for Java SE applications on the desktop might become quite distinguished for some companies since Oracle will drop several distinguished desktop features from the JDK starting with Java SE version 11. If you are using Java SE on the desktop they highly recommend to read the following articles:Important Links Red Hat
Red Hat produces OpenJDK binaries for various platforms that Red Hat Enterprise Linux runs on.Support Options
Red Hat won’t provide Java SE 9 and 10 releases. The next distribution that Red Hat plans to release is OpenJDK 11 for Red Hat Enterprise Linux 7. Currently, Java SE 8 is the supported release for Red Hat Enterprise Linux and the company will support it until 2023.Important Links Java Desktop / Java Web Start / JavaFX
There are a number of changes with Desktop Java SE starting with Oracle JDK 11 that you necessity to exist awake of.JavaFX / OpenJFX
Starting with Java SE 11, neither the OpenJDK builds or the Oracle JDK binaries involve the JavaFX libraries. The JavaFX components will now exist delivered as a sunder SDK, or as artifacts that can exist used via build tools (e.g. Apache Maven, Gradle et al.). As a positive consequence of this decoupling, JavaFX progress can now absorb its own roadmap.
JavaFX is noiseless being developed in OpenJFX, which is a project under the OpenJDK community umbrella. Oracle, other companies and individuals in the wider community are actively developing JavaFX. An automatically synced GitHub mirror is created as well, lowering the barrier for developers to contribute code and issues to JavaFX.
At the second builds for OpenJFX are only provided by Gluon. As outright the OpenJFX source code is 100% open, others can create or deal binaries as well. At OpenJFX, a similar approach as the one in OpenJDK is followed, where after releasing JavaFX 11, the focus is on JavaFX 12 and so on. JavaFX developers and users are encouraged to utilize the latest released version of OpenJFX.
Gluon provides a support arrangement for companies who want Long Term support for JavaFX 11.Java Packager
The javapackager, which allows bundling applications and its dependencies with (a subset of) the JVM is no longer allotment of OpenJFX and is removed from Oracle’s JDK and Oracle OpenJDK builds starting with Java 11. A JEP has been submitted for adding a Java Packaging tool to OpenJDK. While the newfangled Java Packaging tool will not exist ready for the Java 11 release, Gluon is working on a tool allowing Java 11 applications to exist packaged into indigenous images.Java WebStart
If you are using Java Web Start technology to deal desktop clients you should entrap care about the current situation as speedily as feasible since Oracle has removed Web Start from Java.
We recognize that the post above may not absorb the information explained in a manner which answers your exact question. So they absorb a FAQ.OpenJDK variants vs each other and vs Oracle JDK
Q. Differences between OpenJDK vs Oracle’s OpenJDK builds vs Oracle JDK?
We’ll just talk about Java 11+ LTS releases here. Oracle JDK and Oracle OpenJDK builds are identical, but are licensed in different ways (commercial and GPLv2+CE respectively).
Oracle JDK / Oracle OpenJDK builds and OpenJDK builds from other providers will exist built from the same source for the first six months of updates and should exist interchangeable for that period. After six months Oracle JDK / Oracle OpenJDK builds will exist built from Oracle’s own fork. Other OpenJDK providers will continue to create binaries from the OpenJDK updates project. Oracle JDK / Oracle OpenJDK and OpenJDK builds from the other providers may therefore disagree in tiny ways. Binaries from various parties may, of course, vary over time.
Q. Differences between OpenJDK from (non-Oracle) provider A vs provider B?
We’ll just talk about LTS releases here. As has been the case with the Java SE 6 and Java SE 7 updates projects, various providers drudgery together upstream in the OpenJDK community, which provides the common repositories, mailing lists, and other infra to partake the work. This means the divergence between OpenJDK-based binaries are mostly non-core features, dote extended monitoring and diagnostic support. Although there may exist tiny differences in the final binaries (perhaps a provider-specific tool etc) they will outright at least absorb the same security and stability baseline as has been just for many years.Oracle JDK / OpenJDK 8, 11 halt of Public Updates by Oracle
With the Oracle JDK 8 and 11 halt of Public Updates for Oracle happening soon, some folks are unclear on the ramifications:
Q. If I wait on Oracle JDK 8 / 11, carry out I absorb to pay to Get security and bug fixes?
For Oracle JDK 8, for personal desktop use, then no. For commercial utilize after January 2019, then yes. For Oracle OpenJDK builds starting with Java SE 11, after the initial 6 months of updates, then yes.
Q. If I wait on OpenJDK 8 / 11, carry out I absorb to pay to Get security and bug fixes?
Not necessarily. As was the case with Java SE 6 and Java SE 7, Oracle works with the OpenJDK community to transition the leadership of OpenJDK update projects to other contributors. This has worked well for over a decade. It is very likely Red Hat will continue this leadership in OpenJDK 8 and OpenJDK 11 updates with abet from Oracle and other parties. This means distinguished patches will Get selectively backported. You then absorb the altenative of taking downstream OpenJDK based binaries from a variety of providers for free, or as allotment of a paid support offering. In particular, there is an OpenJDK Vulnerability group which deals with 0-day exploits and CVE’s and ensures that fixes Get out as quickly as possible.
Q. Will Oracle’s JDK 8 and 11 noiseless exist available for download (last public release)? For example, a company has software that only runs on Oracle’s JDK 8 and they provision a newfangled machine after January 2019?
You can noiseless download older versions of the Oracle JDK up to the point where the public updates stop. There is no judgement to expect these archives to exist removed. Moreover, Oracle JDK 8 continues to exist free for personal desktop utilize through at least 2020.
Q. If someone is using Oracle JDK 8 to Run commercial software, after January 2019 carry out they necessity to purchase a license?
No. The user can continue to utilize Oracle JDK 8 indefinitely without paying. The only cost is if they want to Get updates beyond Jan 2019, in which case they will necessity to purchase an “Oracle Java SE subscription”. This follows the accustomed “End of Public Updates” process which has been in exercise for well over a decade. Also, note that Oracle JDK 8 continues to exist free for personal desktop utilize through at least 2020.
Q. What happens to Oracle Java Web Start after January 2019? Does it continue to Run or at what point carry out you necessity to purchase a license?
Since Web Start is allotment of Oracle JDK 8 it will continue to drudgery and can exist used indefinitely without cost. As above if you necessity updates (bug fix and security patches) you will necessity to purchase a “Java SE subscription”. If your halt users are consumers, they are covered for free until at least 2020 as Oracle JDK 8 will continue to exist free for personal desktop utilize until at least the halt of 2020. Oracle has stated that they will continue to support (i.e. provide commercial updates for) Java Web Start at least until March 2025.
There is besides IcedTea-Web as an alternative and Karakun is working on an OSS replacement for Web Start.Appendix I — Signatories, Thanks and References

Zendesk is poignant beyond being solely a customer service software vendor and is entering the more CX-focused CRM...
With the industry shift toward unifying sales, marketing and service, a Zendesk CRM reflects that industry transition, but it's already a crowded market with many big players and dozens more filling distinguished niches.
Zendesk is expecting its service background to bring it success across an entire organization, while providing flexibility and public cloud architecture. Zendesk unveiled these newfangled applications and the AWS news at Relate, its annual conference on Nov. 12.
Zendesk besides released Zendesk Sell, a sales oblige automation tool, and Zendesk Explore, a reporting tool. The addition of Zendesk applications that can drudgery across an organization's business process is a common play for CX vendors, with CRM vendors dote Salesforce and Oracle unveiling platform-wide applications this year.
"I assume the pendulum has swung back and forth between buying the best of breed for each piece of CRM stack and going with a platform that has integrated pieces to the puzzle," said Brent Leary, a CRM and CX analyst at CRM Essentials. "You're seeing bigger companies dote Salesforce, Oracle and SAP filling out missing pieces with acquisitions to proffer a more cohesive platform. Zendesk is trying to carry out the same."
Zendesk acquired sales oblige automation vendor groundwork in September, rebranding it as Zendesk Sell to fill its SFA software gap.Benefits of a public cloud
In addition to expanding products to sales and marketing, the Zendesk CRM system -- named Sunshine -- is besides built on AWS, the public cloud architecture the San Francisco-based company said its users were looking for.Customer service vendor Zendesk is expanding into CRM, SFA and analytics with newfangled products, built on top of AWS, allowing for third-party integration.
"The open cloud is the pass modern developers think," said Sam Boonin, VP of product strategy at Zendesk. "We learn from their customers."
Zendesk was built on its own proprietary cloud, but two years ago began a migration over to AWS. By doing that, Zendesk expects it can attract companies that want the insights provided by a connected CRM without being beholden to a platform, dote Salesforce or Microsoft Dynamics 365.
"The business demands of data and processes around CX necessity to flood freely through it, but most users don't want to carry out outright of that in a platform," Boonin said. "Companies that utilize Sunshine can entrap odds of elasticity and cost odds of a public cloud."
Winning in this competitive environment is as much about giving customers the flexibility to create their own ways of working. Nicole Franceanalyst, Constellation Research
By hosting Zendesk CRM on AWS, it makes it easier for other vendors to integrate their APIs with Zendesk, according to Nicole France, analyst at Constellation Research.
"Winning in this competitive environment is as much about giving customers the flexibility to create their own ways of working," France said.
One vendor that is interested in a more open Zendesk is product success software vendor Pendo, which partners with Zendesk and besides uses the product in-house.
"For us, it's about injecting their data into more creative ways throughout [the Zendesk] platform," said Todd Olson, Pendo CEO and co-founder. "The news about Sunshine on the AWS cloud makes it easier to augment the platform."A supple CRM
Zendesk poignant beyond exclusively customer service to being a vendor of sales, marketing and analytics software tools is a significant transition, analysts said.
"Zendesk's inch into CRM is a transparent and timely recognition that to succeed in the digital era, companies must build a comprehensive view of their customers across outright of their interactions with them," France said.
But what Zendesk is trying to achieve with Sunshine is to create a CX platform with flexibility for its users to add other tools -- even if they compete with Zendesk's.
"We're hearing from their customers that they don't want another vendor-locked-in platform," Boonin said. "Part of being an open platform is about saw you don't necessity to utilize every constituent they proffer to carry out your business. It's something you hear often from tech vendors, but they are trying to exist more radically open."
This nexus between using one platform for everything and licensing third-party vendors is where the CX industry is headed, according to analysts. That's why Salesforce spent $6.5 billion on integration vendor MuleSoft and Zendesk migrated from its own cloud to AWS.
"Companies don't want to operate or can't operate by having just one vendor for everything," Leary said. "You may absorb mission-critical apps that you can't Get off of but you dote this other customer assignation stack -- you'll necessity those applications to talk to each other."
Customer pricing of Sunshine, Sell and Explore varies depending on other product subscriptions, business size and number of users.
