>>on oracle forum someone replied to be saying that RAC is a DR solution
Where exactly? All the gent says is
Quote: | Better high availability options are :-
#1. Oracle Standby with Data Guard
#2. Oracle Failsafe on Microsoft Cluster (if windows is your OS)
#3. Oracle RAC (Real Application Cluster).
|
>> if one node fails another instance on another node can still manage the database files,am i right?
Quite right.
Question is, what happens if the database fails?
No other nodes will work~.
You typically have all the nodes in a RAC in the same room.
Assume that building went under water.
RAC provides no help.
The standby database is something you configure in a remote location (DR site)
If the primary site is unavailable, you will find your data in remote DR site.
There is a subtle difference between High Availability and Disaster Recovery.
Both are not the same always.

If you have Oracle DB Standard Edition the RAC license is included for up to 4 CPU cluster.
If your cluster is bigger and/or you have Enterprise Edition, you need to buy the RAC Option. If you have SE1, you need to upgrade to SE or EE with RAC option (again depending on cluster size).
If you decide you need to buy more licenes contact me and I'll help you get a very good price.
