You can backout service updates and restore your system to the previous
service/install level, for any component of WebSphere® MQ for AIX® that
is in the APPLIED state.
To back out a service update:
Before installing maintenance you must end all WebSphere MQ activity:
Log in as root.
Use the endmqm command to stop all
running queue managers.
Stop any listeners associated with the queue managers, using
the command:
endmqlsr -m QMgrName
To check that you have stopped all of them, enter the following:
ps -ef | grep mq
Check that there are no processes
listed that are running command lines beginnings amq or runmq.
Ignore any that start with amqi.
Display the appropriate smit panel using
this sequence:
Software Installation and Maintenance
Software Maintenance and Utilities
Reject Applied Software Updates (Use Previous Version)
Alternatively, use a fastpath command (smitty install_reject).
Complete the SOFTWARE name field. Enter MQM to
restore all applicable fileset updates to your installation.
Note: Although
there is an option to restore only selected fileset updates for WebSphere MQ for AIX,
this still results in all applicable fileset updates for the service update
being restored.
Use the displayed default values for all other fields to reject
the current service level and reinstate the previous service or install level.
Press Enter to display a confirmation message, before starting
the reject process. While the command runs, it displays progress messages
terminating with an Installp Summary table, confirming
which components of WebSphere MQ for AIX have been
rejected.
