OA45407: DIAGNOSE OF A CATALOG GETS REASON: 2 - CELL TYPE NOT RECOGNIZED FOR A GDS IN AN EXTENSION RECORD WITH MULTIPLE ALIASES

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• NOTE: this is a reversal of FIN apar OA44551 to be fixed in
  current releases
  
  
  An IDCAMS DIAGNOSE for a BCS gets IDC21364I with
  REASON: 2 - CELL TYPE NOT RECOGNIZED
  for large GDG's with extension records. This kind of corruption
  can happen for generations which have multiple aliases and
  reside in a GDG extension record (type J).
  
  In the specific case the error happens when a second alias is
  defined to a generation and which requires the generation to be
  moved from the GDG base to an extension record. The alias is
  added to the association cell for the GDS, but the length of
  that cell as well as the number of associations is not changed
  to reflect the new alias.
  
  The invalid cell length causes wrong positioning within the
  catalog entry and makes all cells beyond the association cell
  inaccessible.
  
  Addtional symptom:
  IDC21364I ERROR DETECTED BY DIAGNOSE:
  REASON: 28 - GAT CELL ENTRY NOT FOUND
  
  CATKEYS:  CAT2014 CATGDG CATBCS IDCDIAG
  

Local fix

• Avoid defining multiple aliases to GDSs for larger GDGs (GDGs
  with high limits, GDSs with many candidate volumes, etc).  Once
  the error is encountered, the VVDSfix tool will be needed to
  remove the extension records.  Note VVDSFIX delbcsr may need
  to be issued multiple times.  VVDSfix is supplied by defect
  support.

  DEFINE ALIAS over a Generation data set can lead to issues
  with IDCAMS DIAGNOSE due to catalog structural problems.
  

Problem conclusion

• Code has been added to make sure the DEFINE ALIAS over a
  Generation data set does not cause any structural problems in
  the catalog.
