PI54685: ADS STATUS UNMATCH BETWEEN ACTIVE AND D/S WHEN ADS GOT I/O ERROR

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DEDB had two active ADSs, two Shadow ADSs and two Shadow IC data
  sets. During final phase of DEDB Alter Utility with ALTERAREA,
  2nd CI I/O error happened on old ADS1/ADS2 and new ADS1.
  Finally, new ADS2 kept open and available in Master IMS, but the
  AREA was stopped in Data Share IMS.
  This is a very similar problem as PI47927, but it is on.

  ----------------------------------------------------------------
  As above, Master IMS issued DFS3373I at 2nd CI I/O error on old
  active ADSs during ADS close. This is wrong.
  This ADS close is called from ALTER_ADIS routine in DBFDAU70.
  As same as PI47927 we need to skip global stop at 2nd CI write
  error in DBFMPLC0 even for old active ADS close.

Problem conclusion

• The following changes have been made to correct the reported
  problem:
  
  DBFMPCL0:   Add check to skip 2nd CI error processing during
  ALTER open or close request when other ADSes are available.
