Hi,
Once a week my informix database copy that is restored from a copy of production locks up and won't restore. I can't shut it down, check status, etc. I have to restart the server and then I'm able to bring it back up to an oninit -s and restart the restore with ease.
While looking through the bar_act.log, I see the following errors:

onbar_d -l when performing a log backup-
---24796 24076 ERROR: Unable to start the logical log backup:
Log backup to device '/dev/null' not allowed

onbar_d -r -p -w when restoring rootdbs-
---26542 18438 ERROR: Unable to write restore data to the dat
abase server: could not fork server connection.

An Oninit -ivy shows the following error:
Checking group membership to determine server run modesucceeded
Reading configuration file '/usr/informix/etc/prod01'...succeeded

This happens one weekend night a week for the last two weeks. I've combed through server logs with no luck!
Anyone who has any answers, let me know, I would greatly appreciate it!

Hi,

Please first change in ONCONFIG file LTAPEDEV to /tmp/anyfile.
Remember that onbar look two files; $INFORMIXDIR/etc/oncfg_SERVERNAME.SERVERNUM and $INFORMIXDIR/etc/ixbar.SERVERNUM.
Set RETSTARTABLE_RESTORE = ON
Similarly onbar run back-up of logical logs before run the restore.
Remember to do backup of logical logs before run re
Then test with "ipcs -m" if exist informix segments and kill with ipcrm -m "id".

Gustavo.

Thank you for the information and that's the direction I was looking at as well, but just didn't know where to begin.

Do I need to apply the /tmp/anyfile value to the tapedev parameter as well? This is compatible with Informix 7?

Thank you again for your help!
