IT34139: "RSCGETCOMPDICTROW : DICTIONARY NOT FOUND" FOLLOWED BY LOG REPLAY ASSERTION ON SECONDARY SERVERS

APAR status

• Closed as program error.

Error description

• Secondary servers, with compressed tables, can incur assertions
  and abort following a message that a (compression) dictionary
  couldn't be found:
  
  02/12/20 10:09:50  rscGetCompDictRow : Dictionary not found  -
  rscompress.c : 5961
  02/12/20 10:09:50  rscLoadLatestDict: dictionary retrieval
  failed
  02/12/20 10:09:50  Rollforward of log record failed. iserrno =
  101
  02/12/20 10:09:50  Log Record: log = 158, pos = 0x5f5e7508, type
  = OLDRSAM:HINSERT(40), trans = 7004617173263974700
  02/12/20 10:09:50  Assert Failed: Logical log replay error.
  02/12/20 10:09:50  IBM Informix Dynamic Server Version
  14.10.FC2AEE
  02/12/20 10:09:50   Who: Session(146, informix@s1ayandehdb2, 0,
  0x5032fa19e8)
                  Thread(304, wreplay_51, 5027d55408, 9)
                  File: rsprecvr.c Line: 9184
  02/12/20 10:09:50   Results: The secondary server cannot
  continue.
  
  Upon restart everything will work and continue normally (so
  "Dictionary not found" not meaning the desired dictionary really
  is missing.)
  
  The log record type incurring such assertion isn't significant,
  but the code line being reported (rscompress.c : 5961) is always
  the same.
  

Local fix

• Restarting the secondary will normally overcome the problem
  situation.
