Well Anjo, what sort of hash? I've been working to develop the stuff that Hailey talked about(direct SGA access) at Hotsos seminar but the best I've come up with so far has me sorting through all the shared memory segements seeing which one I can attach to. This is not good. I can get the id's through oradebug but I'm looking for a better way that is not indirectly dependant on connecting to the database.

Oracle knows this because it attaches to a segment based on the hash value of $ORACLE_HOME and $ORACLE_SID. In that segment the $ORACLE_HOME and $ORACLE_SID are stored, so that oracle can see to which instance they belong.
