You can use the Administration Console to suspend and resume message
delivery from JMS connections to MDBs:
If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
In the left
pane of the Administration Console, click
Deployments. A table that lists all the
deployments currently installed on WebLogic Server appears in the
right pane.
In Deployments table, expand the name of the application
that contains the MDB for which you want to suspend or resume JMS
connections.
Click the name of the MDB for which you want to suspend or resume
JMS connections.
Click the
Control tab.
Check the box to left of the table row.
Click Initialize.
Click Suspend or Resume.
To activate these changes, in the Change Center of the Administration Console, click Activate Changes. Not all changes take effect immediately—some require a restart (see Use the Change Center).
