Quiescing MQSeries

The orderly shutdown of MQSeries for AS/400 is called quiescing. You may need to quiesce MQSeries for AS/400, for example, to:

vTake a backup of the system, or

vUpdate MQSeries for AS/400

Quiescing previous releases of MQSeries for AS/400

To quiesce one of the previous releases of MQSeries for AS/400:

1.Use F12 (Cancel) to return to your initial MENU

Note: If you have MQSeries Commands (CMDMQM) as your initial menu, change the initial menu in your user profile, sign off and sign back on.

2.Ensure that you have:

v *ALLOBJ authority, or object management authority for the QMQM and QMQMADM libraries.

v*USE authority for the following programs:

±QMQM/AMQIQES4

±QMQM/AMQIQEM4

±QMQM/AMQSTOP4

±QMQM/AMQSPECA

Notes:

a.If you use QMQM/AMQIQES4 any user signed on to MQSeries, even if that user is not running the product, will be logged off.

b.The QMQMADM library exists only if you have installed the MQSeries for AS/400 Administration utility.

3.Warn all users that you are going to stop MQSeries for AS/400.

4.Warn users not to start Message Queue Interface applications while MQSeries for AS/400 is being quiesced. To ensure that they cannot start, you should revoke users' authorities to MQSeries for AS/400 by issuing the RVKMQMAUT command.

5.Exit the Administration utility, if it is running.

6.Quiesce the queue manager by running program AMQSTOP4:

CALL QMQM/AMQSTOP4 PARM(QMGRNAME *CNTRLD 15)

where QMGRNAME is the name of the queue manager and 15 is a time-out value in seconds.

7.If this fails, you can force the queue manager to stop by issuing:

CALL QMQM/AMQSTOP4 PARM(QMGRNAME *FORCE 15)
