Sounds like a SAP installation to me.  Tell consultant to go fly a kite.
One set of binaries, 5 instances out of the same home.  No options.

It does sound like a real maintenance nightmare.  What is the problem
they are trying to solve that requires 5 identical sets of binaries
under 5 different users, as opposed to (worst case normally), 1 set of
binaries and 5 instances?

 We have been proposed with following architecture by our consultant. I
need your expert opinion on this.
 Assume a server got 5 database and all the databases running in same
oracle version and patchset. 
They are proposing to create 5 unix account. Each unix account will have
one oracle binaries and corresponding oracle DB. Apart from that each
unix account will have dedicated mountpoints. In broader sense each unix
account will be logically considered as one server. 

 I am slightly worried about this architecture. Because when this
architecture goes to production, the impact it will have on maintenace
going to be huge. Assuming i am having minimum 100 db in production(
ours is a very large shop) and if i need to apply one patch to all these
servers going to kill us. Secondly, will there be a impact on licensing.
I don't think so, but like to check it up with you guys. I know it has
got some advantage too. But is this approach is suitable for large shop
like us?
