PH29910: PREVENT POTENTIAL ABENDU1234 WHEN DIAGNOSIS DD STATEMENT ALLOCATED FOR AN UNLOAD REQUIRING A SORT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• An ABENDU1234 can occur during the run of an
  unload step that fulfills the following conditions:
  
  the diagnosis DD statements (reserved $xxxxx DD statements) are
  specified.
  the unload requires a sort process invoked by Db2 HPU
  the sort program invoked by Db2 HPU updates the access registers
  and does not restore them to the values at invocation time as
  advisable and expected
  To make Db2 HPU more robust to such a not compliant behavior of
  the sort program,Db2 HPU should save the access registers before
  the sort invocation and restore them after the sort program has
  returned.
