Old WLST tools

sghattu — Thu, 03 Dec 2009 00:56:54 +0000

As you might know after the acquisition of BEA Systems by Oracle, Dev2Dev site has been discontinued. Unfortunately I don’t see a replacement for that, not only we lost some rich information, but a number of good tools.

In that context, in the last few months I had inquiries from some users asking where they could find the original WLST that works with WebLogic 8.1 and 7.0, also WLST Script Generator and Console extension that work with WebLogic 9.x.

Now you can get these from the new google code project wlst-modules. WLST Script Generator 9.x can be downloaded from here. The zip contains a ReadMe.html that should walk you through the configurations steps. And for those unfortunate souls who are still using WebLogic 7.0 and 8.1, WLST jar can be downloaded from here.

My takeaways from Oracle Fusion Middleware 11g Forum

sghattu — Thu, 30 Jul 2009 02:25:03 +0000

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.. .

Can WebLogic 10.3 run on JDK 1.4?

One of my colleague asked me whether he can upgrade to WebLogic 10.3 from WebLogic 8.1 and not upgrade his JDK to 1.6. 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.

Default protocol in WebLogic and why is it important

sghattu — Sun, 26 Jul 2009 21:17:12 +0000

If your WebLogic Server makes outbound connections to other systems it is wise to know what a DefaultProtocol is. Generally, when you create a WebLogic domain and haven’t configured SSL you will not have to do anything.

But once SSL is configured and you have dis-abled the non-ssl port, you should make sure that the DefaultProtocol your WebLogic Server uses is SSL (either t3s, https or iiops). If you haven’t done this, your WebLogic Server will try to use “t3″ (default) for any outbound connections and since the ListenPort is disabled it will fail.

Here’s a simple wlst script to change the default protocol to t3s for all the servers in the domain.

# After connecting to the Admin Server

edit()

startEdit()

servers = cmo.getServers()

for i in servers:

i.setDefaultProtocol(“t3s”)

save()

activate()
