we have all 3 versions, 6.0.1,6.1 and 6.5 IS’s running on the same box in dev,stg and prod HPUX-11iV2.
The only problem is that you can’t use the same jvm folder for all 3 IS’s. I noticed this problem when we upgraded our JVM, as 6.5 requires a minimum of 1.4 to run. So, I downloaded the latest JVM for hpux from HP’s site. I tried to use the same JVM for IS 6.0.1 and it failed to start because of the jar file ‘jce.jar’ present in the …/jre/lib’ folder. The irony is that,
a version 6.5 IS wont start up without the jce.jar file and version 6.0.1 IS will not start up if the jce.jar file is present. webMethods advised us to use the JVM that comes with the installer.
FYI.
