How do I know what group Oracle expects to run as? · 4 May 2008, 12:29

Learned the hard way about how picky Oracle is about the group it runs as … do not change the group ownership of files owned by Oracle unless you have the .c source for the distribution of Oracle you are using and a lot of time to fix :p ..

The group Oracle runs as is found in the files


You can also do a ‘strings’ command on config.o and you will see the group name.

Unfortunately in my case the version of Oracle came with the commercial product (eHealth) and the only thing we found we could do was reinstall … took our in-house database staff to figure out what the problem was, CA left our ticket open for over a month without a resolution (RMAN backups were failing, not a trivial problem).

really getting tired of the lack of support commercial support contracts provide, seems like support used to be so much better back in the old 90s :p.
