Description:

How to increase the JVM size for the Notification Service?

Resolution:

To increase the memory size of the OpenFusion Notification Service Java Virtual Machine you need to do the following:

1. Bring up Administration Manager
2. Click on "Notification Service" and go to "JAVA" tab
3. In the "JVM Flags" option enter the following:
   -Xmx<SIZE>M
   Where SIZE is the size in MB you want to give to the service. e.g. -Xmx100M allocates 100MB maximum for the service memory.

When deciding on a maximum JVM heap size for NotificationService, you will need to consider the number of objects and events. Each object in the service -- channel/admin/proxy -- requires memory, as does each event that flows through the service. The maximum heap size chosen must consider the number of channels and the highest expected event rate.
