When installing Performance Center, memory usage is set by a combination of questions and automatic evaluation of the system resources.
If you increase memory on the host, you need to manually edit the wrapper.conf file for each service for Performance Management to make use of these new resources.

How much memory is allocated for the different services? The formula for memory allocation is:
The remainder of the memory will be for the OS and PC MySQL implementation.
To modify the memory each service is allocated for use we edit the wrapper.conf file for each service. Each has one in the following locations using default paths.
Open the file for a given service and find the following line.
# Maximum Java Heap Size (in MB)
Set the value as needed per the formula above. Here we see it's set to allow use of 10 GB of RAM in MB. (10 GB*1024 MB=10240 MB).
Restart each service whose wrapper.conf was edited. The wrapper file is only read during service start.
To validate the setting is in use, examine the process listings for each process.
The value is seen in the -Xmx entry in the process.
For the example above we'd see -Xmx10240m for the service set to use it.
