Weren't these parameters deprecated in 11g ?

Question

Version  : 11.2.0.3
Platform : RHEL 5.8
All our 11.2 DBs (RAC & Single Instance) still seems to have background_dump_dest, core_dump_dest and user_dump_dest parameters set.
I was under the impression that these parameters were replaced by diagnostic_dest. We have diagnostic_dest set too.
These DBs are created as per the standard build ie. Created according to the instructions by our engineering team which apparently are bight guys.
Is this expected behaviour?

BTW.Where is the preview button which we had in our earlier Forum interface ?

Answer 1

The diagnostic_dest parameter specifies the base for the directory structure that contains all diagnostic files, and that structure cannot be changed. For example, the location for the alert log is $DIAGNOSTIC_DEST/rdbms/<database_name>/<instance_name>/trace, which is where the background_dump_Dest is set to. You can set it to something else, and you will a little stub alert log that says, in effect, "I'm not using this":
c:\tmp\bdd>cat alert_orcl112.log
Dump file c:\tmp\bdd\alert_orcl112.log
