OLDS|WADS DEALLOCATED ON ddname

Explanation

The first form of the message appears when IMS restart takes place and the online log data set (OLDS) is ready for use.

The second form of the message is issued each time the OLDS (ddname1) becomes full, EOV was forced, or OLDS (ddname1) incurred an I/O error and was closed. The next OLDS (ddname2) is opened for further logging. During an XRF takeover, the second form of the message appears. ddname1 is the OLDS that is terminated from the WADS when takeover is requested.

The third form of this message appears when normal shutdown is scheduled and OLDS is closed.

The fourth form of this message is issued o the master terminal when some OLDS are forced to stop, by a /STOP command or because of I/O error. The log data set is no longer needed for online database backout, and the log data set is removed from the candidate list for future use. This OLDS is dynamically deallocated from the control address space.

If automatic archiving is not specified, display the OLDS status to determine whether to submit an archive job.

When the fourth form of the message appears, the specified OLDS is ready for repair. After the OLDS has been archived, the data set can be scratched and reallocated on another volume. Then the /START OLDS command can be entered to reconnect the OLDS to the online IMS.
