Disabling notification threads

You must disable notification threads if you are running a notification on a single cluster.

About this task

If you are running a notification on a single node in a cluster, you must provide the following JVM parameter to disable notification threads on a particular cluster node.

-Ddm.suppressNotifications=true
  • If the WebSphere Application Server cluster has four nodes, then you need to add the JVM parameter in three JVM cluster nodes except the one you want to run the notifications.
  • If the WebSphere Application Server cluster has four nodes and you added this JVM parameter in two nodes and notification threads are enabled on more than one cluster node, then there is a chance multiple notifications are sent.
