IBM WebSphere MQ maintenance tasks

This section describes how to apply and remove maintenance to IBM® WebSphere® MQ.

Applying and removing maintenance level updates on UNIX, Linux, and Windows
When you apply and remove maintenance level updates to IBM WebSphere MQ, no migration is required. Maintenance level updates are applied either as a fix pack, or by manually applying an interim fix. The following topics describe how to apply and remove fix packs on UNIX, Linux®, and Windows.
Applying maintenance level upgrades to multi-instance queue managers
Use multi-instance queue managers to reduce the outage caused by applying maintenance updates. Follow these steps to apply maintenance to a multi-instance queue manager.
Migrating queue managers to new-function fix packs
This scenario illustrates running different levels of queue manager from a single installation using new-function fix packs. New function fix-packs are available on platforms other than z/OS®. It contrasts migrating a queue manager to new command levels in new-function fix packs, to migrating a queue manager to a new command level in a new release. The scenario explains the relationship between new-function fix packs and maintenance fix packs.
Querying the maintenance level
Query the IBM WebSphere MQ maintenance level by running the dspmqver command
UNIX, Linux, and Windows: Staging maintenance fixes
Use multiple installations of IBM WebSphere MQ on the same server to control the release of maintenance fixes.
