Cluster_database_instances

[khussain]

I have 1 node right now, that I need to create a 'RAC-able' database on-Instance 1. After a month, I will get the 2nd node, which will have the Instace 2 of the database.

What should I set his parameter to now ( 1 or 2) to create the database ?
CLUSTER_DATABASE_INSTANCES

I am guessing 1, and as the increase, I can increase this parameter also ? Is this tight ?

boy o boy!

first clear the concepts of RAC. Minimum number of nodes for a RAC is TWO.

and never heard of "RAC-able" Database.

Not so simple. I can install two instnces of rac, then kill one of
them,
and work with one instance of "RAC" without any problems.

Well i didn't say that u cannot work with one instance on RAC.

Here the question is setting up of RAC. The initial stage. Can you set up RAC with one node... ??

Installation of rac with a one instance possible.

1. u have to install cluster software (os scpecific) + oracle custer software without cluster manager
2. start cluster software
3. start gsd on one node only
4. start oracle insatller on one node and choose only one currrent node
5. install Oracle cluster manager on this node only
6. install Oracle database software on this node only
7. manually activate this node only, using srvctl utility and declare only one instance for this database.
8. manully install db using sqlplus (not dbca)

thats coool !

but what about the raw files and the shared disk ?? does this solve the whole purpose of having a RAC... (High Availibility, Load Balancing)...

And what next, how will i now add another node

try ww.oaktable.net, there is a paper of how to install RAC in a labtop using vmware by James Moore

I told you its not a good idea to have it on one node...

(or may be im not able to get it, still says that file does not exist)
