Ghattu's Technology Blog » WebLogic 10.3 http://ghattus.com A blog about technology that I work on in my day to day job Thu, 03 Dec 2009 00:56:54 +0000 en hourly 1 http://wordpress.org/?v=3.3.1 My takeaways from Oracle Fusion Middleware 11g Forum http://ghattus.com/2009/07/29/my-takeaways-from-oracle-fusion-middleware-11g-forum/ http://ghattus.com/2009/07/29/my-takeaways-from-oracle-fusion-middleware-11g-forum/#comments Thu, 30 Jul 2009 02:25:03 +0000 sghattu http://ghattus.com/?p=85 I attended the Oracle Fusion Middleware 11g Forum in Bridgewater, NJ. It was a pretty informational session and I got to talk directly to Oracle management about some questions I had regarding Oracle’s Portal and JVM Strategies.Here are my takeaway’s.

  • WebLogic Server 10.3 MP1 is part of Fusion Middleware 11g.
  • WebLogic Portal is NOT part of the Oracle Fusion Middleware 11g. The portal product that is part of Fusion Middleware is Oracle WebCentre.
  • Oracle will continue to develop and innovate on WebLogic Portal and planning to release 11g version by the end of the year.
  • JRockit is the recommended JVM for Oracle Fusion Middleware 11g.
  • Oracle does not have any plans to merge Sun’s JVM and JRockit into one, both these JVM’s will be independent of each other.
  • JDeveloper is the recommeded IDE for all products in the Fusion Middleware suite.
  • Oh lastly, Enterprise Manager is the mother of all Managers and will be able to control the Universe.. :-) .

Well, my initial reaction was “Why would you want to do that????”. But after listening to his side of the story I did wondered if WebLogic 10.3 is supported on 1.4. His application was built around 5 years ago on WebLogic 8.1/JDK 1.4 and slowly every one in the team moved on to different things. Now due to EOL and other issues (see my post on JDK 1.4 and WebLogic 8.1 EOL) all the the applications co-hosted in the Datacenter would like to Upgrade and he is forced to upgrade also. With limited or no resources how can he pull off this upgrade with out any code changes? Well, lets wish him luck.

Checked with Oracle and offcially WebLogic 10.3 is NOT supported on either JDK 1.4 nor JDK 1.5.

Since WebLogic 8.1 runs only on JDK 1.4, BEA announced EOL for WebLogic 8.1. This is the statement from BEA Support site.
After the EOL date, WebLogic Server and WebLogic Platform configurations that run on J2SE 1.4.2 will no longer be running on fully supported configurations. BEA will continue to support these environments on a best-effort basis. Lack of support from an SDK vendor, however, may limit BEA’s ability to resolve certain SDK-related issues.

If you care about not using EOL products in your Application stack, you have 2 Options and a dilemma to deal with.

Option 1:
The obvious, migrate your application to JDK 5 or greater. This depends on the complexity of your application, for all you know all you have to do is deploy your application to WebLogic 9.x or 10.x and fingers crossed your application with run flawlessly.

Option 2:
If you believe you cannot make the October 2008 deadline, contact Sun and see if you can extend your support contract to include support for JDK 1.4. If you have some extra budget you probably would go with this easiest no hassle option, atleast for now.

Dilemma:
Well, the dilemma is if you upgrade to WebLogic 9.x or 10.x, you will have to upgrade again in October 2009, because both these versions of WebLogic only support Java 5 which is going EOL in October 2009.

There is no WebLogic version out there that supports JDK 6 yet, from my reliable sources WebLogic Server 10.3 is slated for release end of July, 2008.

My Suggestion:
If your application uses the base WebLogic Server, I would wait for 10.3 release and migrate to it hoping that 10.3 is released on time. You will have 3 months to migrate giving you an ample time to test and deploy your application. If you are using WebLogic Platform products like WebLogic Portal or WebLogic Integration you may have to wait for those products to be released, since these Platform products are usually released a few months after the base WebLogic Server is released.

If you cannot wait until 10.3 is relased, BEA made the Technology Preview of WebLogic Server 10.3 available. You can download it and test your application to make sure you do not see any major issues.
