RE: Why is this happening ?

Posted By:

Scott's right.
Sending logs to /dev/null results in an "SOL" situation for you.
/dev/null is special. Informix won't bother to check other settings, if
it sees dev/null, it simply flips a bit to mark the log backed up
without really doing anything with it.
However, if you set this to /dev/null only for the restore, but normally
run with a setting to something other than /dev/null, you probably do
have logs backed up as you indicated. Maybe you were just trying to
avoid the log salvage that Informix does on restore? If so, check on
the storage manager side for messages. Obviously Informix knows what
log it wants, but the storage manager can't help.
In our case, our storage manager (Veritas Netbackup) initially backs up
our logs to disk. We hold X days on disk, then we have a secondary
Netbackup process that takes those logs, backs them to tape, and empties
the disk directory. We use the second Netbackup process because it has
a different catalog than the first one. If the first netbackup process
backed these to tape, it would change the records in it's catalog and
would not be able to give informix the log when requested.
We have tested situations where we knew the log was backed up to disk
and properly recorded by both Informix and Netbackup. Then we renamed
the log on disk, then we tried to restore. Informix knew what it
wanted, Netbackup understood, but returned an error that the log could
not be found. When we renamed the log to the proper filename, Netbackup
happily passed it back to Informix and all was well with the world.
I don't know about all the storage managers, but Informix and Netbackup
produce verbose messages that are quite understandable.

If indeed you did back up the logs, try the restore again without the
/dev/null setting and see what happens.
good luck,
Norma Jean
