Java Heap Space Out of Memory wtih Websphere Admin Console

Question

I am not able to open the Administrative console of websphere application server v8.5. The logs report Java Heap Space and Out of Memory errors. I have searched online and the suggestions are to increase the JVM heap size. But how should I accomplish that now, when even the admin console is not working for me ?

Is there a method to free up the heap space somehow ?

Answer 1

Search for a file named server.xml in your WebSphere installation. Generally, the location of this file is as follows:

<profilehome>/config/cells/<cellname>/nodes/<nodename>/servers/<servername>/server.xml

Select the server.xml specific to your server and edit it to add/modify/delete the attributes initialHeapSize and maximumHeapSize of the element <jvmEntries>. The value of these attributes is the heap size in MB.

For example:

 <jvmEntries ... initialHeapSize="2048" maximumHeapSize="3072" ...>
 ...
 </jvmEntries>

Then restart the server.
