Hi,
OBIEE 11.1.1.7.160119
I am struggling with a strange issue. We have 5 OBI instances. In 2 instances, I am getting this "No Log Found" error message when I try to view log for an OBIEE report via Administration -> Manage Sessions -> View Log. I am able to view the log in remaining 3 OBI instances. All these instances have been setup the same way (as far as I know) for approx 2 years now. While checking the performance for a report, we noticed this strange behavior.
So I compared all the 5 instances and all the below settings are consistent across all the instances.
Repository - Logging level is set to 0. I see lot of links suggesting to set this to 2 minimum. I have no idea why it is working for us in certain instances.

Enterprise Manager - FMC - logging level is set to Info.

List of values for Log Level

If I set the log level for individual report by adding the below text to the report -> Advanced Tab -> Prefix text box, I can view the log.
SET VARIABLE LOGLEVEL=2,DISABLE_CACHE_HIT=1;
Since all the settings are same across all the instances and it is working for some and not for others is more confusing/bothering. How can I go about troubleshooting this issue?
Thanks in advance.
