IBM Support Assistant Out Of Memory when opening heapdump .phd file


I am using IBM Support Assistant 5 on my local machine. I am trying to open a heapdump file (.phd) file that I have grabbed from the server where I've had an out of memory error and copied it to my local machine. The file size is 915 MB.

Inside IBM Support Assistant I am using the Memory Analyzer tool (desktop). When I launch this tool there is a screen which allows you to specify the min heap and max heap. I have played around with trying to increase the maximum heap size from 1024 to 7500 but no matter what I do with these settings I get an outOfMemoryError in the tool after it spends x minutes trying to parse the heap dump.

enter image description here

I am running Windows 7 with the following JVM.

java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) Client VM (build 25.51-b03, mixed mode, sharing)

The heapdump was created on a WebSphere 6.1 server.

Can someone please suggest to me a way that I can work through this so as to be able to open and analyze the heap dump.


Solution

  • If you have trouble running memory analyzer from ISA, you can download and run standalone version - Heap dump analyzer
