RE: multiple oracle homes

I agree with Dennis. We tried this several years ago and decided it was best to stick with one username. I forget what the exact issues were - it might have been file privileges when you are upgrading a database.

Thanks for you replies.  I've never tried this before and it seems like
there are two different approaches on the surface:

1. use two different userids, ora817 and ora920, to do the install.  This
seems stupid, since it replicates the product directory structure and
oraInventory stuff under different ownership.  This might be safer since
it is like running one version in that everything is seperate, but
maybe there are operational issues to not using the oracle userid.
Seems like there may be a gotcha waiting in the wings.  Like maybe you
can't run the same listener for both, or worse.  

2. use the same oracle userid for both installs and change the environment
vars as needed.  Seems like you could damage the first install if you
made a mistake.  Also, it seems like in a stressful failure situation
you don't want to have to think about who's on first?  I don't know, 
third base.

Are both paths valid?
