-XX:+HeapDumpOnOutOfMemoryError

[Former Member]

Dear all,

we have an J2EE stack in Release 7.02. There is no Option set in the Config Tool like -XX:+HeapDumpOnOutOfMemoryError.

But the J2EE stack generates out of memory dump files by an out of memory like heapdump.xxxx.xxxx.xxxx.phd. What can I do to disable the writing of the heapdump files?

Best regards

XX:+HeapDumpOnOutOfMemoryError is valid only for Sun/SAP JVM. For IBM JVM check -Xdump related parameters, like -Xdump:heap, -Xdump:system:events.

mhmmm... I've checked system properties and also Config Tool... I can not find Xdump parameters.

If this is a default manner, how can I negate this?

I assume the the correct parameter : -Xdump:none and/or -Xdump:heap:none

Can I capture/check the default manner?
