RE: Out of Memeory RPG calling Java

Have you tried running in the 64-bit jvm? The first line of your dump appears to show that you are using 32-bit ppc j9 vm.

For the record, the classic JVM was 64-bit. If this application used to run ok on previous releases, then perhaps your upgrade to 6.1 changed your default jvm to the new j9 vm (32 bit). Do you have a system environment variable to define JAVA_HOME? Use "WRKENVVAR LEVEL(*SYS)" to see if you have this defined.

If you already have the 64-bit j9 vm installed (5761JV1 Opt 12 Feature 5112 Java SE 6 64 bit) then you could just

Change Environment Variable (CHGENVVAR)

Type choices, press Enter.

Environment variable . . . . . . > 'JAVA_HOME' Character value
New value . . . . . . . . . . . '/QOpenSys/QIBM/ProdData/JavaVM/jdk60/64bit'

Changing the *JOB instance of this environment variable before you launch into Java forces the selection of the desired JVM.

Subject: Out of Memeory RPG calling Java

We are calling java classes from RPG and have a batch job which is handling a lot of data falling over (We have the the same job with lower amounts of data , where everything is fine)

In the RPG we have no Garbage Collection in place. Could this be our problem.
