PK42406: BATCH BACKOUT REQUESTS PREVIOUS LOGS INVALIDLY BECAUSE IT MISINTERPRETS TYPE47 LOG RECORDS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If a Type47 log record contains a UOR entry that has residual
  data, then the Batch Backout Utility may request previous log
  data sets while attempting to locate the start of the UOR.

  DFSBACK0 assumed that every entry in a TYPE47 record represented
  an active work unit.  When it found an entry for an inactive
  PST, it would pick up the residual UOR and find no subsequent
  log records for that PST.  It would issue DFS2298A requesting
  earlier log data so that it would have the log data for this
  apparently active work unit.

  *** END IMS KEYWORDS ***
  DFSBACK0 has been modified to test each TYPE47 record entry for
  its status.  Each entry contains a copy of PSTSWR so DFSBACK0
  will test for PSTSWR2.  Only entries for active PSTs will be
  recorded.
  
  It was also noted that DFSBACK0 assumed that a single TYPE47
  record would contain all active PST information, but there may
  be a group of TYPE47 records if one record cannot contain
  enough entries.  DFSBACK0 needed to be able to detect a complete
  TYPE47 record group.  For this reason a new flag, CAPRCD1, was
  added to the TYPE47 record to indicate the first of a group of
  TYPE47 records.  DFSRCP10 will set this flag in the first
  TYPE47 record and both DFSBACK0 and DFSULG60 will use it to
  verify that a complete active UOR list has been obtained.
