Same as a regular,single instance database.
Drop the files, clean oratab, clean init.ora files, clean $ORACLE_BASE...

Additonally, you need to use srvctl to remove specific instances and database settings from CRS.
If you are using dedicated diskgroups for ASM, clean them if you want.
Using DBCA is most recommended.

>> Please give the steps
I would not recommend something which i would not do it myself for my databases. Smile

As said before, the manual 'steps' are not standard. It depends on your environment.
>> if I do normal database it is showing errors.
What errors?
Post exactly what you did (your session screen shots) along with errors.

Since this is a RAC database,
you need to set

Code: [Select all] [Show/ hide]

CLUSTER_DATABASE=FALSE

and do a

Code: [Select all] [Show/ hide]

startup mount restrict

I think we can not give CLUSTER_DATABASE = FALSE becoz before that database is shutting down.So How to include and Where we have to set the CLUSTER_DATABASE = FALSE.

IF i set in the script it is giving errors...

connect SYS/<syspwd> as SYSDBA
shutdown immediate
CLUSTER_DATABASE=FALSE
startup mount restrict
drop database;
exit;

I hope this database does not contain anything of value.

WOW, it appears you have decided to avoid reading any documentation & have proceeded into wonton flailing at Oracle.

You'd be better off just reformatting the whole system.

If you are not aware of setting init.ora parameters, you are not supposed to be doing these kind of operations.

Already the parameter "cluster_database= false" in both the instances of cluster environment. If I do the below steps I am getting the below errors.

I know how to change the cluster_database parameter but already it is false.

Hi,
Quote:

Using DBCA is most recommended.

Is it enough if we use dbca to delete a 2 node rac database ? or Is something else should be done before invoke dbca to delete database like remove instance , stop database or deleting database files manually etc...

Pls note that this question is related to delete a multiple node rac database using dbca utility.

Srini

Didn't you say in one of your recent topics that you have already used dbca to drop a RAC database?

Hello ,

I once used the following command to drop a database in RAC environment and it was successful.
Code: [Select all] [Show/ hide]
/u01/app/oracle/product/11.2.0/DB1/bin/dbca -silent -deleteDatabase -sourceDB AD0001C -sysDBAUserName SYS -sysDBAPassword Passw0rd then insure that /etc/oratab is clean on all nodes
My question is shall i use the same command to drop a database for standalone database ?
Can you clarify ?

Regards,
Srini
