Nw2004s Java - IBM SDK - How to fine tune


Can you anyone let me know about tunning IBM SDK parameters on Linux using configtool ?

We have already set some parameters as per SAP Note for IBM SDK.

Still not sure, how to set the following in the configtool

1. HeapDumppath

2. HeapDumpon CtrlBreak

If I XX:HeapDumpPath=/usr/sap/dumps , JVM is not starting. The same setting Sun JAVA JDK on Solaris is working fine.

I believe the syntax is different for IBM SDK than Sun JDK.

Thanks in Advance for your help !

    Please check the following SAP Notes:

    Note 1004255 - How to create a full HPROF heap dump of J2EE Engine 6.40/7.0

    Note 1053495 - Settings to get a heapdump with IBM JVM on AIX

    Note 710146 - How to change J2EE Engine JVM Settings

    Hope That helps.
