IT33677: VERSION UPGRADE CAN FAIL WITH NO CLUE AS TO WHAT'S WRONG

APAR status

• Closed as program error.

Error description

• An upgrade from older version to e.g. version 14.10 can fail
  early on without any information what's wrong:
  
  09:20:40  IBM Informix Dynamic Server Version <new_version>
  09:20:46  Conversion from version <old_version> Started
  09:20:56  Checking partition header pages for needed free space
  09:20:56  Checking for free space in partition header pages
  succeeded
  09:20:59  A restore point was created and data is being stored
  in directory <restore_point_dir>/<server_num>.
  09:20:59  Conversion control block initialization
  09:20:59  Succeeded
  09:20:59  Initialization of Conversion Session
  09:20:59  The restore point ended and related data in directory
  <restore_point_dir>/<server_num> were removed.
  09:20:59
  09:20:59  Conversion failed.
  09:20:59  FAILED
  09:20:59  Restart conversion after fixing the problem.
  09:20:59  oninit: Fatal error in shared memory initialization
  
  With this precise scenario, there are two possible reasons for
  this failure:
   - the physical log not being logically empty (left over from
  <old_version> shutdown)
   - at least one logical log before the current one not flagged
  as backed up ('B')
  

Local fix

• Restart old version, make sure there all logs are flagged 'B'
  (if only by resetting LTAPEDEV to /dev/null) and perform a clean
  shutdown using onmode -kuy.
