4.5 Controlling the Change Log Started Task

The RACF exits add information about events to an in-storage cross memory queue as they occur. The Change Log Started Task moves events from this queue to the Change Log data set, where they await processing by the driver.

Start the Change Log Started Task during your IPL procedure before user processing begins. Any RACF events of interest that occur are stored in the cross memory queue until the Change Log Started Task has initialized.

You can briefly stop the Change Log Started Task if necessary. Any RACF events of interest that occur while the Change Log Started Task is not running remain in the cross memory queue, and are written to the Change Log data set when the Change Log Started Task is restarted.

Stop the Change Log Started Task during your system shutdown procedure after all user processing has ended. Any RACF events of interest that occur after the Change Log Started Task shuts down remain in the cross memory queue and are lost when the system is shut down.
