PM53250: EYU9XDUT UTILITY JOB TAKE A LONG TIME UNDER Z/OS V1R12

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• EYU9XDUT job spends huge amount of time after migrating to z/OS
  V1R12.In our case EYU9XDUT job finishes about 1 min on z/OS
  V1R10 but on z/OS V1R12 EYU9XDUT job does not finish even 3 hrs
  after. EYU9XDU1 always issues SNAP macro although SNAPDCB is not
  opened.On z/OS V1R12 or later SNAP routine checks DEB from
  DCBDEBA.Program check is raised if DCB is not open because of
  invalid DEB address(x'00404040'). Recovery processing takes
  place and it takes a long time.
  EYU9XDU1 should not issue SNAP macro if SNAPDCB is not opened.

  ****************************************************************
  * PROBLEM DESCRIPTION: You submit CPSM utility EYU9XDUT to     *
  *                      upgrade an EYUDREP file. On a           *
  *                      pre-z/OS 1.12 system, the utility       *
  *                      finishes relatively quickly. On a       *
  *                      z/OS 1.12 system, the utility may       *
  *                      take many times longer, up to several   *
  *                      hours.                                  *
  ****************************************************************
  * RECOMMENDATION: Rerun the EYU9XDUT utility using the module  *
  *                 updated by this PTF.                         *
  ****************************************************************
  In CSECT EYU9XDU1, a SNAP SVC may be issued to dump before and
  after record images. If the open for the target DD statement
  fails, the SNAP SVC is still issued. On z/OS 1.12 and higher
  systems, this causes additional recovery activity which
  increases runtime substantially.
  

Problem conclusion

• EYU9XDU1 has been updated to bypass the SNAP SVC if open for
  the target DD statement has failed.
