Tuning web services reliable messaging applications
Modifying certain settings, such as heap size, can help to improve the performance of your system.
Procedure
- Tune the heap size of the JVM. Increasing the
heap size, for example to 1536, can avoid out-of-memory errors, especially
in the following situations:
- When you are composing WS-ReliableMessaging with WS-Notification.
- When you are using a Reliable Asynchronous Message Profile (WS-I RSP) policy set.
- When you are using WS-ReliableMessaging in situations where a lot of recovery is required.
- If your application uses a managed quality of service, tune the sib.wsrm.tokenLockTimeout property of the messaging engine that is specified in the policy binding for the application. See the service integration custom properties information to learn more about this property, and why you might want to change its value.
