During normal operation, Rhino removes SBB entities when they are no longer needed to process events on the activities they are attached to — usually when all those activities have ended.
Sometimes, however, the normal SBB lifecycle is interrupted and obsolete entities remain. For example:
-
An SBB might be attached to an activity that didn’t end correctly, due to a problem in the resource adaptor entity that created it.
-
The
sbbRemovemethod might throw an exception.
Unexpected problems such as these, with deployed resource adaptors or services, may cause resource leaks.
Rhino provides an administration interface, the Node Housekeeping MBean, which lets you find and remove stale or problematic:
-
activities
-
SBB entities
-
activity context name bindings
-
timers.

When using the pool clustering mode, it is only possible to inspect or remove the application state owned by the node that the management client is connected to. To inspect or remove application state owned by any other node, a management client needs to connect directly to that node. |
