SAP Memory Analyzer problem

[Former Member]

Hi All,

I tried to use Memory Analyzer 1.1 on a heap dump generated in WAS when I got an OOM exception and the .hprof file could not be opened and a alert box saying that a NullPointer Exception had happened. Can you please advice as to what to do.

Regards,

Novik

Hi Novik,

can you post the NullPointerException (as an attachment)?

Kind regards,

Maybe it's a browser specific stuff... but if I add a new comment, right below the input box, there is an "Attach Files" input line. Otherwise send it to andreas dot buchen at sap dot com.

Well, let me give you a quick follow-up about this posting:

hprof originally is an agent which can write memory maps from a running VM. As such, it can also run on IBM VMs, however, it produces only a textual output which (a) is very slow to generate and (b) does not contain all data necessary for the analysis.

So to be more precise, the Memory Analyzer works with hprof formatted binary heap dumps. These heap dumps are written by current Sun, HP and SAP virtual machines. Check our Wiki pages for the concrete version numbers.

In this particular dump, a IBM VM was used and the output not readable.
