Data Guard: archive log target fix

Oracle Database Tips by Donald Burleson


Question:  I have implemented Data Guard successfully and I have set the archive_log_target = 600 (10 minutes) and everything seems fine, except I get the follow error on the data guard screen in Grid Control

ORA-16792: configuration property value is inconsistent with database setting

It seems to function fine, but if I press the ?Verify Configuration? button in Grid Control on the Data Guard screen, it goes though the verification process, sets the archive_log_target to zero, and clears the ORA-16792 error.

I set the value like this.

alter system set archive_log_target = 600;

I tried using this command

alter system set archive_log_target = 600 scope=spfile;

and the message said 'system altered? but the value was still zero.  The value also sets itself back to zero during a shutdown/restart when I do nightly backups.


Answer: First, make sure that you have the Oracle Data Guard book, and review the scripts.  On the data guard verification wizard in OEM Grid control, there is a "Broker Managed" option and a database option for fixing the problem. 


I'd been using the Broker option, so I used the other one which I believe wrote the value to the init.ora file, and un-setting the broker option seems to have fixed the archive_log_target problem

If you like Oracle tuning, see the book "Oracle Tuning: The Definitive Reference", with 950 pages of tuning tips and scripts. 

You can buy it direct from the publisher for 30%-off and get instant access to the code depot of Oracle tuning scripts.
