This should be the case with DLM. Usually DLM goes down and comes up along with the cluster. To make this happen u have to execute following command

scadmin clustername ?U filename i.e. clustername.ora_cdb

Once u execute above command, they say DLM is registered with the cluster and the DLM goes down and comes up with the cluster automatically. But I don't know what happens when u stop DLM using some DLM command, whether cluster automatically senses it and brings it up within a second or so.

I think something similar is configured for db_startup scripts on your cluster. I don't know how it is done for db_startup.

Please check in /etc/opt/SUNWconf/conf/cluster_name.ora_cdb and /etc/opt/SUNWconf/conf/cluster_name.cdb

U may find something related to this in these configuration files. Read the commented part also.

Hi,

If I shutdown my database, sun cluster will automatically startup it within a second.

Regrads,

I don't see any problem in stopping Oracle Database and keep the cluster running. Stop the database from svrmgr prompt on all nodes using just shutdown normal/immediate and don't execute anything related to cluster. This way u will have access to all shared storage (raw / filesystems) and your database is down for cold backup.
Now, if u are using raw shared device, then the backup cab be taken through 'dd' and if u are using filesystems, then u can use anything u want.

Hi all,

I want to perform Oracle cold backup,

Since I am using Sun Cluster 2.2, after I stop my cluster, those clustered partitions are not mounted.

How can I shutdown my database while my cluster is working (How to shutdown my Oracle with mounted partitions)

Best Regards

Sinardy
