WebLogic "lite" Administration Console

Wednesday, July 23rd, 2008

If you have used WebLogic 8.1 console and planning to upgrade to 9.2 or 10.x, boy you are in for a surprise! Well, its good and bad. The good part is of course the new look and feel, lot’s of new functionality, wizard based configuration and much more. The bad part is, you will immediately notice the heaviness of the Application. It is slow compared to what you were used to with 8.1 console, more clicks and page refreshes to configure resources. That said, if you are looking for a “very” light weight console that can get the job done in way few clicks than the console, you should check out Cypal Lite Console.
I had the oppurtunity to test drive the “lite” console which is in its technology preview version. There isn’t much functionality implemented yet, you can only configure a JDBC Resource for now but you can clearly see where this application is going. The console is pretty light, clean, fast and to the point. For kicks, I compared the time it took me to configure a JDBC resource using the lite console and with the Admin Console. It took me 1 minute 20 seconds with the Admin Console and only 30 seconds using the “lite” console, impressive! I will be curious to see how the JMS and other complex configurations will be handled.
Few minor things I found that can be improved;

  • The login screen needs the username, password and the url of the server, there should be no reason to input the url since the appis deployed on the Admin server you better know the url.
  • I wasn’t able to connect via https

Things I would like to see;

  • J2EE Deployments, including libraries
  • Simplify WLDF and WorkManager configurations
  • Today there are many options for developers for configuration, there are not many tools out there for monitoring. Hope the “lite” console provides some monitoring capabilities.

Overall the console looks pretty impressive and promising and clearly geared towards a “power” “super” Console user.. :-)

Java 1.4 and WebLogic 8.1 End Of Life

Saturday, July 12th, 2008

As you might already know Sun announced End Of Life for JDK 1.4 to be October 2008. 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.
