PM19212: NEW HANDLING OF AN EXCEPTION TRANSACTION NEEDED WHEN IT SPANS TWO OR MORE ATF JOURNALS

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• ATF journals are archived as they become full. Problem occurs
  when an exception transaction spans 2 or more ATF journals,
  resulting in an incomplete transaction being recorded in the
  extract file.
  
  Additional issues addressed in this APAR:
  1) Loop in IPIOPROC at about 7 instructions near x'16cc'
  to near x'171a' when using a large amount of ATF data
  coming from the OMEGAMON IF2 function.          Keyword: looping
  2) "Program name" field incorrectly displayed on the OMEGAMON
  ATF Trace Level 3 report of IMSPA. The field shows as:
  Program:   *  * **
  Although this is coming from the data, IMSPA should not be
  printing such asterisk garbage in the output.  The data is
  derived from the DB2 Program name field ATRSQLPN in the ATF
  records which contains Hex characters.
  3) ABEND0C4 IPI4PROC at x'EF8' trying to access R1 storage
  using ATF Extract facility.
  4) ABEND0C4 out of RECA05 in IPIOPROC which is in IPI4PROC.
  This issue can show up in various locations in IPI4PROC, so
  any ABENDS0C4 in this routine should have this maintenance on.
