APAR Error Description / Circumvention

-----------------------------------------------
Locks are orphaned if a cursor is open for a DELETE statement
and a connection serviced by a QZDASOINIT job ends abnormally
during an XA transaction.

CORRECTION FOR APAR MA40656 :
-----------------------------
Fast DELETE, where all the records are deleted, uses a LENR
(lock exclusive no read) lock on the data space.  Under XA
transactions this LENR lock causes an unexpected and not handled
conflict during close processing for the cursor.  The LENR
condition will now be handled to allow a full close of the
cursor.

CIRCUMVENTION FOR APAR MA40656 :
--------------------------------
None.
