Love to hear from the OP.

However, as an Oracle user, I think the idea is switch SIDs without having to source in oraenv.

In other words, making switching SIDs easier.

Why switch SIDs? Maybe you have more than one instance? It's an ok use case thing.

If switching SIDs is just something done from inside of a script, I'd just set my ORACLE_SID and source in oraenv.sh, done.... but there could still be a desire for something better than this.

Imagine if ORACLE_SID could be a path. Then the SID could be the basename and the other ORACLE elements could be folders (or symlinks) off that ORACLE_SID path if env vars aren't specified, etc... just an idea. And certainly not something I expect Oracle to do.
