Issue:
The CA WA DE imexutil script does not start due to the following errors.
 
Error occurred during initialization of VM.
Unable to allocate 129600KB bitmaps for parallel garbage collection for the requested 4147200KB heap.
Error: Could not create the Java Virtual Machine
Error: A fatal exception has occurred. Program will exit.
Environment:
CA Workload Automation DE 11.3/12.x
OS: Any
Cause:
The script is unable to start the JVM due insufficient free memory.  The script will start an external JVM and has limited JVM arguments.  The Java will then try to acquire heap of up to 4GB, if it cannot acquire it, the initialization will fail.
Resolution:
Increase the memory and/or virtual memory on the host. If this is a high-availability setup, run imexutil on standby to connect to primary.
