Hi guys,

Need help to fix the subject problem, what I did is to add a new node to an existing cluster with the following steps:

1. To add clusterware on the new node :

2. To add database softwre to the new node :
[xml]./ -silent "CLUSTER_NEW_NODES={Sol4}"[xml]

3. To create an instance for the new node :
[xml]dbca -silent -addInstance -nodeList Sol4 -gdbName Sols.localdomain -instanceName Sols2 -sysDBAUserName sys -sysDBAPassword ************[xml]

srvctl config database -d sols
[xml]Database unique name: Sols
Database name:

Instance terminated by USER, pid = 18546[xml]

As you can see its using the instance number = 1 for the new instance which is already running on the other node.

What I would like to know :

1. Is it a bug in oracle ? shouldn't it have created 2nd instance with a different instance number ?
2. How do I fix it now ?

Thank you very much for your help in advance.

Best regards.
