Changing the BSDS

You do not have to take special steps to keep the BSDS updated with records of logging events because IBM® MQ does that automatically.

However, you might want to change the BSDS if you do any of the following:

Add more active log data sets.
Copy active log data sets to newly allocated data sets, for example, when providing larger active log allocations.
Move log data sets to other devices.
Recover a damaged BSDS.
Discard outdated archive log data sets.

You can change the BSDS by running the change log inventory utility (CSQJU003). Only run this utility when the queue manager is inactive, or you might get inconsistent results. The action of the utility is controlled by statements in the SYSIN data set. This section shows several examples. For complete instructions, see The change log inventory utility.

You can copy an active log data set only when the queue manager is inactive because IBM MQ allocates the active log data sets as exclusive (DISP=OLD) at queue manager startup.
