Name Description
Name of

Name of Singleton Service.

MBean Attribute:
SingletonServiceMBean.Name

Changes take effect after you redeploy the module or restart the server.

Class Name

The fully qualified name of a class to load and run. The class must be on the server's classpath.

For example, mycompany.mypackage.myclass

MBean Attribute:
SingletonServiceMBean.ClassName

Changes take effect after you redeploy the module or restart the server.

Additional Migration Attempts

A migratable service could fail to come up on every possible configured server. This attribute controls how many further attempts, after the service has failed on every server at least once, should be tried. Note that each attempt specified here indicates another full circut of migrations amongst all the configured servers. So for a 3-server cluster, and a value of 2, a total of 4 additional migrations will be attempted. (the original server is never a valid destination)

MBean Attribute:
SingletonServiceMBean.AdditionalMigrationAttempts

Changes take effect after you redeploy the module or restart the server.

Sleep Time Between Attempts

Controls how long of a pause there should be between the migration attempts described in getAdditionalMigrationAttempts(). Note that this delay only happens when the service has failed to come up on every server. It does not cause any sort of delay between attempts to migrate otherwise.

MBean Attribute:
SingletonServiceMBean.MillisToSleepBetweenAttempts

Changes take effect after you redeploy the module or restart the server.
