Onbar logical restore fails

Posted By: BART GROOT
Date: Monday, 9 July 2007, at 5:45 a.m.

Hello,

After setting up a new 9.40.FC4 informix server and configuring onbar with TSM I tested backup and restore. Backup of both dbspaces and logical logs turned out to go fine. I performed a level 0 backup and forced a log switch to test logical log backup. All OK. Then I created a database and waited a few minutes to perform a point in time restore to a point in time prior to creating the database. The created database should then not be present after the restore. The physical restore went fine, however when performing the subsequent logical restore I encountered problems causing the Logical restore to suspend (message in message log, see below). In addition the following message was shown to me:

$ onbar -r -t "2007-07-05 15:00:00"
You cannot switch logs while Dynamic Server is in fast recovery.

IDS then showed the following status:

IBM Informix Dynamic Server Version 9.40.FC4 -- Fast Recovery (CKPT REQ) -- Up 00:13:54 -- 613152 Kbytes
Blocked:CKPT

The message log (as shown below) suggested to me that this situation appeared when performing a logical recovery of logfile 10.

To get the system running again I tried to restore up to log 9 (onbar -r -n 9). This turned out to work fine and the system came on-line again.

I cannot seem to find the reason why the point in time restore failed. Since we also use this mechanism on our production system I want to be sure we don't run into these problems when we need to perform a restore on our production systems.
Therefor, has anyone experienced this problem before? And is there something I am doing wrong/missing? How can I prevent this situation to occur?

Thanks for your help.

Regards, Bart
