To Migrate EJB Timers
If a GlassFish Server instance is stopped, Enterprise JavaBeans (EJB) technology timers that are installed on that instance also stop running. If the instance was stopped abnormally or unexpectedly, To enable these timers run while the instance is stopped, you must migrate the timers to a running server instance in the cluster.

In the navigation tree, expand the Clusters node.
-
Under the Clusters node in the navigation tree, select the cluster.
The General Information page for the cluster opens.

On the General Information page, click Migrate EJB Timers.
The Migrate EJB Timers page opens.
Note:
If all instances in the cluster are running, the Migrate EJB Timers button is deactivated.

List of GlassFish Server instances in the cluster.
- Timer Count
