Hi,
On RAC there is a single database. Each RAC instance runs on the very
same database.

RAC is a shared everything architecture - nothing at all like the
inferior (shared nothing) cluster technologies used by many of the
other database vendors.

In other words, a database resource (table/sequence/view/procedure/
etc) is available on all that database's cluster instances.

Regards
Sandy

"nothing at all like the inferior (shared nothing) cluster
technologies used by many of the other database vendors."

Not sure about the meaning of 'inferior' here...

Cheers.
