Setup PeopleTools 8.52 PIA

Yesterday I was setting up a PIA for an CRM9.1 Demo environment and ran into below warning:


This version of PeopleSoft PeopleTools requires a 64-bit Oracle WebLogic
installation. The selected Oracle WebLogic is a 32-bit installation. Are you
sure you want to continue?

Since I didn't install the weblogic on the server, I had no idea if the weblogic that was pointed to is 32 bit or 64 bit. After tweaking a few things and still the same issue, I decided to reinstall weblogic. To ensure weblogic is 64 bit, the key is to use 64 bit java to install weblogic. Below is how to check if your java is 32 bit or 64 bit:

./java -d64 -version
Running a 64-bit JVM is not supported on this platform.

This means this java is not 64 bit.

 ./java -d64 -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Oracle JRockit(R) (build R28.1.0-123-138454-1.6.0_20-20101014-1350-linux-x86_64, compiled mode)

This means this java is 64 bit.

Once I reinstalled weblogic with 64 bit java, the warning during setting up 8.52 PIA disappeared.
