Hi

We are using a 64bit processor on a solaris OS. We need to install Weblogic 9.2 MP3 on this architecture.

What is the recommended JDK version i.e 32bit/64 bit ? that we should be using with the weblogic server & why?

Any help is greatly appreciated

Does weblogic mention any preferences ? It would make sense to use the 64bit JDK. That can take advantage of the underlying architecture. I am not aware of a serious bug that would prevent you from doing this. Write to BEA (oracle ) and ask them.

BEA/Oracle mention that they recommend 64 bit JDK for a 64 bit processor. When asked why, the reply was that 32 bit JDK would cause crashes, & that 64 bit would give better performance.

Has anyone got/point us to any numbers/theory to validate their claim?

If that is their recommendation better follow it. Surely you do not want crashes in production
 
I agree. Here's the link: http://aspose.com/file-tools
