Is there something like "-XX: OnError" or "-XX: OnOutOfMemoryError" in the IBM JVM?

The following options are available in the Java HotSpot virtual machine settings:

-XX:OnError="<cmd args>;<cmd args>" Run user-defined commands on fatal error. (Introduced in 1.4.2 update 9.) -XX:OnOutOfMemoryError="<cmd args>; <cmd args>" Run user-defined commands when an OutOfMemoryError is first thrown. (Introduced in 1.4.2 update 12, 6)

As far as I can see, such features are not available in the IBM JVM.
Is it correct?

I need to call some shell script in case heap heap has been created.
What is the easiest way to do this?

The IBM J9 JDK offers the specified ability via the Xdump flag ; This is the preferred way to register dump agents.

A typical way to configure the JVM to dump heaps on OOME is to catch all Out Of Memory errors caused by the application or JVM and prepare a dump for the walk (using the heap inspector).

 -Xdump:system+heap+java:events=systhrow+user,filter=java/lang/OutOfMemoryError,request=exclusive+prepwalk+compact

Link: Eclipse Memory Analysis Guide

You can also use the JAVA_DUMP_OPTS environment variable . See the IBM JDK Diagnostic Guide for more information on this.

EDIT

To run a command in OOME, the tool parameter must be specified in the -Xdump option.

- Xdump is your friend and very powerful.

For your case with OOM, something like:

"- Xdump: Tool: events = cast, filter = * OutOfMemoryError, process = cmd_to_run

I expected the IBM JVM to support the same flags as the instrumental version of the Sun JVM, if I remember correctly. Is it possible to compare command line options between major versions of Java? (Ie Sun 1.6 vs IBM 1.4.2?)

If you don’t find a solution for flags, you can take advantage of the fact that the IBM JVM updates the /tmp/dump-locations file by adding the full path to the dump file. The cron task can run your script when this file is affected since it was last run.
