Oracle and /,/usr,/var


I am wondering if anyone has a nice comprehensive list of all the OS partition places that Oracle database installations stuff their special files. I am not asking about ORACLE_BASE,_HOME,_TMPDIR,etc... I want to know about stuff that gets tucked into /usr,/var,

e.g. it looks like:

Some systems have stuff in: /etc/oracle/*

All systems that I have available have stuff in: /var/opt/oracle/*

Anywhere else? Thanks. Also, configurable?

I think those are configurable as long as you maintain a separate mount points for Oracle during installation. But /usr is already part of vg00 and you may need less 1GB space for Oracle.

Thanks, points to come later.

Any advice on approach for ServiceGuard installations (as regards all these side-show files?)? Is there a good doc link that you can provide.

Line of thought is that you need all that "stuff" on each node in an SG cluster to allow failover/startup to work.

Additional context:

I am used to SSI systems like trucluster. Now I am trying to remind myself about package based HA systems like SG.

Re: Oracle and /,/usr,/var

Hi Adam,

My results are similar to Peter's with the addition of /etc/oratab, as well as the usual OS files for the "oracle" user (e.g. /var/spool/cron/crontabs/oracle).

I made use of this command:
# find /var -user oracle -group dba -print
