How to increase Heap size for System Agent?



When the Agent is out of memory or could not allocate heap of requested size, it may prevent the Agent from starting or processing new jobs.  If this occurs frequently, then it is recommended to increase the JMV Heap size for the Agent.

The parameter that controls the memory available to the Agent is;


    -Xms implies minimum heap size
    -Xmx implies maximum heap size
    nnn is a multiple of 64MB

For example:

To increase the heap size; add given parameter in the agentparm.txt file (located in agent installation directory);


And restart the agent to apply changes.

Note: Increase Xmx as per the size of your workloads and resources available on the Agent box.
