Engine Memory Configuration

Feature

Steps to adjust the memory available to an Engine.

Configuration

In the Germain the Workspace:

• Open Germain State

• (Optional) Search for the Engine to clean up the list

• Select the Engine that needs it’s memory adjusted

• Modify the memory setting (-Xmx#g)

• Save

• Click “Restart this Engine”

You can verify the change has taken effect by watching the logs, or by looking at the “Command Line” for the Process.

Default Parameters:

• -server

• -Xms256m (you may need to adjust Xms based on the number of components running inside the engine)

• -Xmx1024m (you may need to adjust Xmx based on the number of components running inside the engine)

• -XX:+CrashOnOutOfMemoryError means that the JVM will crash / exit when there is not enough memory to continue; otherwise the JVM will continue running code in a potential faulty state.

• -XX:-HeapDumpOnOutOfMemory means that the JVM will not create a heap dump when it has an out of memory crash. These are large and unnecessary as the logs will have enough data to determine the cause.

• -XX:-CreateMinidumpOnCrash means that the JVM will not create a Minidump when it crashes. These are unnecessary as the logs will have enough data to determine the cause.
