Suspending a connection to DB2

If you want to apply maintenance or service to the DB2 tables or plans related to shared queues without stopping your queue manager, temporarily disconnect from DB2, using the MQSC command SUSPEND QMGR FACILITY(DB2). Reconnect to DB2 using the MQSC command RESUME QMGR FACILITY(DB2). There are restrictions on the use of these commands. See WebSphere MQ Script (MQSC) Command Reference for details.
