APAR Error Description / Circumvention

-----------------------------------------------
Database restore performance shows waits in #dbmonrl when many
database files have RI constraints.

CORRECTION FOR APAR MA44469 :
-----------------------------
Enhanced SQE I/O costing is being performed async to the object
creation.  This is causing conflicts during the early phases of
the restore.  We've added additional object level optimization
to be more selective in this I/O costing processing.

CIRCUMVENTION FOR APAR MA44469 :
--------------------------------
None.


Activation Instructions


None.
