In this post I'll show you to remove the node from an existing Oracle 10g RAC.
I'll perform the following steps to do the same.
1. Remove the instance using DBCA utility from the first node.
2. Remove the node from the Cluster.
3. Reconfigure the OS and remaining hardware.
Verify that there is a current backup of the OCR.
#./ocrconfig -showbackup
Run the DBCA from first node.
The instance has been deleted from the Cluster. Lets check it by the login into one of the instance.
Lets remove the node from the cluster.
Before proceeding make sure that database resource is not running on the node which is going to be delete.
If it is running on that node then run the below command to move it on re-locate it on the other node.
#./crs_relocate ora.rac.db
Remove the Listener from the evicting node.
In my next post I'll show you, how to upgrade the Oracle Clusterware from version 10205 to 11203.
