Multiple version of DB in the same machine

I ve' installed multiple versions of DB in the same machine.
Since all have the different ORACLE_HOME and different SID name, It is woking fine.

If I install multiple versions of DB with same SID_NAME, Is this going to be OK, as long as I use seperate ORACLE_HOME?

- Curious chobo.

Good question. I think if each have their own oracle homes, and proper environment configurations it should work.

Make two test instances and find out :)

OK. I will tell you the result after testing.
Thanks

I don't think so.
SID=System Identificator.
For example, in NT the listener in Services is identified (concatenated) with the Oracle Home name but it is not the same for instances.
Bye!

I have not tested this yet.

Is there anybody who really tried this?

thanks.

I tested.
This did not work.
Client can not connect to the database, for the same SID name.
