IBM AIX Platform and IBM JDK

[Former Member]

Hi,

We are having out of memory issue on IBM AIX 5.3 version and IBM JDK 1.4.2 J9. All the settings for jvm parameters have been made as per sap recommendations. Now that we need to debug this issue using some java profiler tool. We tried using Sherlok but this does't seem to work on AIX platform. SAP Memory analyzer is a great tool but unfortunately is not supported with IBM JDK.

so what is the best way to troubleshoot out of memory heap issues ? which tools needs to be used for ibm platform and ibm jdk ?

Hi,

unfortunately I do not have a good answer for you. We are working together with IBM to enable the Memory Analyzer read IBM system dumps. However, this will take another 6 months to materialize.

In the meantime, the Diagnostics Guide (http://www-128.ibm.com/developerworks/java/jdk/diagnosis/index.html) might be helpful. Also look for HeapAnalzer and HeapRoots.

Andreas.
