I was wondering if anyone out there knows how to change the parameters of the JVM when running a java plugin within WMQI.

We are running a iWAY plugin (iWAY adapter to R/3) and we are generating a 3.8 meg XML message out of the java plugin. I can see this happening and the XML finishing within the iWAY plugin. It then ( I believe) tries to hand it back to WMQI and I get the OutOfMemoryError.

Has anyone seen this and know what and where JVM options need to be adjusted for MQSI ?

Complete error below.

Thanks
Mike

Search for "OutOfMemory" in this forum and you will find related posts explaning how to increase JVM heap size for Broker/Config Mgr.
On which platform your Broker is running?

mqsireportproperties <broker-name> -e <EG-name> -o ComIbmJVMManager -r -- this displays the current values

Increase the heap using the below command:
mqsichangeproperties <broker-name> -e <EG-name> -o ComIbmJVMManager -n jvmMaxHeapSize -v <size in bytes>
