Installing Oracle Software on Local Disk Vs Shared Disk

[Hari Vetsa]

Hi

I am investigating on several options for a multi node VCS cluster to
house oracle databases.

Where would it be most advantageous to install Oracle Software
(*) Either on a local disk each per system Or
(*) on shared disk per "hagroup".

Any ideas are appreciated.

Installing binaries on each node (not on shared disks) allow you to
upgrade the database on one node and then swicht over and then update
the second node. During this time the service is not interrupted. For
sure this can only be done if the upgraded version has the same database
schema. (generally for minor releases or patches)

You have also to consider license. Installing on the shared disk demands
only one license. Installing on the two nodes demands two licenses.
(This may be subject to change depending on OS, country or other
factors).

Your second point, about licensing, is of course complete and utter
clap-trap.
