Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• IMS cancelled with WTOR in BMP that created Type 47 Record
  - /ERE IMS
  (These 2 messages are expected)
    - DFS982I I/O ERROR READING BACKOUT QUEUE, COVERING SYSTEM
  CHKPT =
    - DFS981I  DBD=PDHDKAO  WITHIN PSB=PLAPJK24 STOPPED DUE TO
  BACKOUT
  FAILURE for all DBs
   TSOSPOC:  UPDATE DB NAME(PDHDJ*) START(ACCESS)
  /DIS DB still shows Backout needed after /Sta DB is done for
  some parts
  /STA DB gets DFS0488I RC=35
  Verify of DB fails because of incorrect data
  Can't see anything in SYSLOG that would cause this failure.
  
  /DIS DB DBHDOK01 shows ALL parts are available.
  /DIS DB DBHDOJ01 shows most parts are available.
  A couple parts are still STOPED,NOTOPEN,BACKOUT
   26, /dis db pdhdjk7
  It looks like Type50 records are not maintaining
   the backout chain pointers correctly. Several, but
   not all, pointers are off, causing a lot of databases
   to be skipped in the backout process.

Problem conclusion

• GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  DFSFLLG0 was storing the offset part of the DBCKCHN information
  before testing for and calling any exit specified by PRMLLXEP.
  This caused the exit to pick up the prior record's block
  sequence number with the current record's offset.
  
  DFSFLLG0 has been changed to set all DBCKCHN information after
  moving the record to the buffer.
