OW00184: VTAM INTERNAL TRACE FORMAT BAD RECORDS - VIT AP A2 CPP3 CPR3 CPW3 LNKB LNKH LNKI LNKL LNKV LNKX TGM2 TREB TRN2 ENTRIES

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The CIO option of the VTAM internal trace was selected and
  MODE=EXT was specified.  The trace was formatted using AMDUSRFD
  (AMDPRDMP formatting routine), and the LNKV trace entries con-
  tained zeroes or blanks instead of the correct data.  All the
  LNK type entries are incorrect (LNKB, LNKH, LNKI, LNKL, LNKV,
  AND LNKX).
  Additional entries that are bad are AP, A2, CPP3, CPR3, CPW3,
  TGM2, TREB, and TRN2.
  For V4R2 (201), the VIT entry SRT2 was added and is also bad.

  ****************************************************************
  Several VTAM Internal Trace entries were formatted incorrectly.
  The first data entry to be put into the trace record was missing
  a pointer to the data. This caused the trace record to be
  formatted incorrectly, displaying bad data.
  
  The trace entries found to be in error were AP, A2, CPP3, CPR3,
  CPW3, LNKB, LNKH, LNKI, LNKL, LNKV, LNKX, TGM2, TREB, and TRN2.
  

Problem conclusion

• Macro ISTVITDL has been modified to include a pointer to the
  data in the first data entry of the trace record for the A2,
  CPP3, CPR3, and CPW3 VIT entries.
  
  Macro ISTVITDS has been modified to include a pointer to the
  data in the first data entry of the trace record for the LNKB,
  LNKH, LNKI, LNKL, LNKV, LNKX, TGM2, TREB, and TRN2 VIT entries.
  
  Module ISTRAFCD has been modified to include VIT entries AP and
  A2 as tyo-byte VIT entry IDs.
  
  Modules AMDUSRFD, ISTRAFCB, ISTRAFCC, and ISTRAFCE have been
  recompiled to pick up these changes.
