When the active log is written

The in-storage log buffers are written to an active log data set whenever any of the following occur:

• The log buffers become full.

• The write threshold is reached (as specified in the CSQ6LOGP macro).

• Certain significant events occur, such as a commit point, or when a WebSphere MQ BACKUP CFSTRUCT command is issued.

When the queue manager is initialized, the active log data sets named in the BSDS are dynamically allocated for exclusive use by the queue manager and remain allocated exclusively to WebSphere MQ until the queue manager terminates.
