The Effect of STATEMATCHPREFIX on Prerequisite Checking

Once SSM determines that a prerequisite check is needed, it compares the current state of each prerequisite with the table-relative UP state for the table in which the prerequisite is stored.

The STATEMATCHPREFIX parameter can be set to NO to indicate that resources should be considered UP for prerequisite purposes only if their current state exactly matches the table-relative up state.

If the STATEMATCHPREFIX parameter is set to YES, then the prerequisite is considered to be UP if the table-relative UP state, treated as a prefix, matches the current state of the prerequisite.

This allows a started task that is in an UPBEGIN state to be considered UP for prerequisite purposes.

The effect of this parameter on positive and negative prerequisites and subrequisites is the same as that of normal prerequisites.
