CORRECTION FOR APAR MA39066 :
-----------------------------
When cascading deletes the system's database manager must inform
commitment control of an acquired lock before performing a
delete operation.  Thus if a resource lock limit is reached by
commitment control, there will be no need to rollback the record
for which the limit was hit.
