A single /orasoft instead of /u01 is OK by me, and I don't particularly
like or need the app/ portion, but the oracle/ portion is based on
userid and clusterware/infrastructure in a best-practices env goes into
it's own BASE
So:
/orasoft/oracle OR /u01/oracle is ORACLE_BASE for stuff owned by oracle
amd
/u01/grid is ORACLE_BASE for stuff owned by grid
Under the Oracle Base, there is a new plethora of directories
ORACLE_BASE/diag (which should be a separate mount point due to
growth)
ORACLE_BASE/data (sub SID could be separate MP)
ORACLE_BASE/fra (common for all??)
ORACLE_BASE/admin (which should include bunches of stuff in OH/dbs
and there should be
ORACLE_BASE/logs
so I see
ORACLE_BASE/product as useful
In my case, I also have a bunch of non-DB products, so I end up with
ORACLE_BASE/product/database
ORACLE_BASE/product/middleware
ORACLE_BASE/product/management (cloud or grid control)
- this one gets an additional layer: OMS, OMA
and so on
And since I test multiple versions of each, the next level down is the
version, and then the HOME - see my SLA comment
A HOME should ideally be a mount point, as I've seen silly
configurations fill up the Home with logs, or control file autobackups
or other stuff.
And by maintaining Cary's mount point strategy, I can quickly toss or
add new subs.
Of course, that is theory, and any SysAdmin and DiskAdmin orth their
salt will explain about how difficult it is to maintain all these mount
points and file systems and collapse it to one. (Which can take out all
the Oracle stuff in one simple runaway log session. But that's a story
of a different colour. Need to make tings easy for the SAs and DAs.)
