Hi,

How to find all the instances (already running and not running) at os level.

I tried with the following cmd.

$ ps -ef | grep pmon

But the output is only running instances. I want to find all the instances.

Regards,
suresh

ps -aef | grep pmon

If you find one process...
that's mean your machine has one instance ... running.

Check fron pfile and spfile
You can go to $ORACLE_HOME/dbs PATH.
$ ls init*
$ ls spfile*

Or use "dbca" command and then check from window screen.

There is no way to get a sure list.

This will not work when you have multiple ORACLE_HOME's.

If this is your box, then you should know what is installed. Else check the ORATAB file (provided that it is up to date).

Else look at the pfiles as mentioned before here.

looking for pmon processes will tell you what is up and running.
