Usage Notes


The DSMFMT utility formats new volumes to use with the DSMSERV EXTEND LOG
command.

The server can be restarted after successfully extending the recovery log.
At this time, the size of the recovery log, the database backup trigger full
percentage, or both need to be adjusted to allow for successful future
database backups.
Examples

Task

If the server has used all available recovery log space, a database backup
cannot complete. The server halts, and there is not enough recovery log to
restart. The DSMFMT utility is used to format a 21MB volume named
adsm.new.reclog for a recovery log extension.

The task is to extend the recovery log using the new volume. After the
recovery log is extended, the server can be restarted.


Command:
dsmserv extend log adsm.new.reclog 20
