Backout

Backout is similar to demote with the obvious difference in the way the jobs are structured.

Once the SP backout is successful then the active version row for this subsystem and this package will be removed (it will be re-established should the SP be installed again).

If versioning is not active then backout will consist of DROP/CREATE using the re-instatedfrom-backup version of the SP component.

Backout skeleton changes

The backout mechanism for Stored Procedures (and other Db2 objects such as UDFs and Triggers) has been divorced from CMN50 and implemented as part of CMN49. The same advantages apply as for the install skeletons.
