Informix - Problem description

Problem IT34139 Status: Closed

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

product:
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10
Problem 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.
