The Effect of STATEMATCHPREFIX on Prerequisite Checking

Once SSM determines that you need a prerequisite check, SSM compares the current state of each prerequisite with the table-relative UP state for the table that stores the prerequisite.

Set the STATEMATCHPREFIX parameter to NO to indicate that resources are considered UP for prerequisite purposes only, if their current state matches the table-relative up state exactly.

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

This setting allows a started task 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.
