Hyperion Modules Optimizing Performance by Changing the Heap Size

Depending on your environment, you might need to change the heap size for your Java web application server. 

For example, if you see “OutOfMemory” errors in WebLogic, increase the heap size. 

If you need to reduce the memory requirement of the WebLogic Server, decrease the heap size.

By default, if you deploy Java web applications to a single managed server, EPM System Configurator sets the default heap size for the single managed server based on the machine's memory:

• 12 GB or more on machine, sets heap size at 8 GB
• 6 GB or more, up to but not including 12 GB, sets heap size at 4 GB
• Under 6 GB on a 32-bit machine, sets heap size at 750 MB
• Under 6 GB on a 64-bit machine, sets heap size at 1.536 MB
