The change log inventory utility (CSQJU003)

The WebSphere MQ change log inventory utility runs as a z/OS batch job to change the bootstrap data set (BSDS).

Through this utility, you can invoke these functions:

NEWLOG
Add active or archive log data sets.
DELETE
Delete active or archive log data sets.
ARCHIVE
Supply passwords for archive logs.
CRESTART
Control the next restart of WebSphere MQ.
CHECKPT
Set checkpoint records.
HIGHRBA
Update the highest written log RBA.

Only run this utility when WebSphere MQ is stopped. This is because the active log data sets named in the BSDS are dynamically added for exclusive use to WebSphere MQ and remain allocated exclusively to WebSphere MQ until it terminates.
