CO-LOG file
In addition to the diagnostics traces, SESAM/SQL also provides the CO-LOG file for collecting information on a DBH session. This log file is DBH-specific (see the “ Core manual”). The DBH generates them when logging is turned on.
The CO-LOG file is a log file for request logging. You can use the SET-TUNING-TRACE administration statement to turn request logging on and specify the data volume for the CO-LOG file (see "SET-TUNING-TRACE"):
SET-TUNING-TRACE TRACE=*ON(...)
You can use the same statement to terminate request logging to the CO-LOG file:
SET-TUNING-TRACE TRACE=*OFF
TA-LOG and WA-LOG files
The transaction log files (TA-LOG files) and the restart log file (WA-LOG file) are DBHspecific files created by the DBH at the beginning of the session (see the “ Core manual”).
Consistency checks within the transaction restart require the TA-LOG files and the WA-LOG file of the relevant session as additional diagnostics documents along with the dump file.
