The Java memory heap is sometimes increased when performance slows on your Process Automation server. This can be caused by the load or the available memory on your server. By default Process Automation sets the initial and maximum memory to 128 MB and 1024 MB.

In PAM 3.1 we now allow Administrators set the memory heap through the PAM user interface. A technical document detailing these steps is available on

In version 2.2 and 3.0 these settings needed to be changed manually through the <IT PAM Install Folder>\server\c2o\bin\c2osvcw.conf. Open the c2osvcw.conf and change the following values:

1536 MB is the maximum Java Heap Size limit for 32-bit JAVA.

Once configured you will need to restart the Process Automation service.
