RE: Is there any way to rebackup a logical log that has been marked as backed up?

Art,
11.50FC5.
I do have LTAPEDEV set, so you are telling me that I don't have to worry about multiple execution.
We think that what is happening is that we have a setting wrong in omniback (somewhere)
that is backing up the logical
logs to disk along with the dbspaces, but log_full.sh is still being kicked off.
I like your log_full.sh versus alarmprogram.sh because its simple and concise.
Thanks,
Todd.

No, but what version of Informix are you running? If you are running 11.10 or later you can set LTAPEDEV to the directory name and ontape will take care of renaming the log archive files and of preventing multiple copies of ontape from running out of the ALARMPROGRAM. Then you can use the alarmprogram.sh that IBM delivers in $INFORMIXDIR/etc/ just change BACKUP_CMD to 'ontape -a -d' and BACKUPLOGS to 'Y'.
Also, note that using a version of my log_full.ksh if there are multiple logical log files full at the time the script gets kicked off (usually because a previous run failed for space or something) or if another log fills while ontape is still running, the log archive file may contain multiple logs and there will appear to be a gap in the file name numbering which will look like a log archive file is missing, but all is well.

We've been backing up logical logs to disk for some months using a modified version of Art Kagel's log_full.sh
command. Its been going well, but I noticed that sometimes, if logical logs get marked as complete fast enough,
some of the logs seem to drop into the bit bucket rather than go to disk. This may be due to my compressing
the logical log in the script and somehow multiple copies of log_full.sh running simultaneously. I've fixed the
problem by adding a lock file, but I appear to have missing backups. Any way to reback these up?
Thanks in advance,
