5. Create a tnsnames.ora entry for the new instance on all the nodes in the site.
6. Register the new database instance with the Oracle Clusterware sub-cluster on remote site:
# srvctl add instance -d hrdb -i hrdb3 -n SJC_3
7. Modify the RAC package configuration on the remote site to add the details of the new node
at the remote site.
8. Start the Site Controller Package.
Deleting nodes online on the primary site where the RAC database package stack is running
To delete nodes online on the primary site where the RAC database package stack is running:
1. Halt the Site Controller Package in the DETACH mode.
2. Halt the RAC database package only on the node that must be deleted. Then remove the RAC
database package configuration.
For more information on halting the package and removing the RAC database, see the
Serviceguard Extension for Oracle RAC toolkit documentation.
3. Delete an instance from the RAC database.
For more information on deleting an instance, see the documentation available at the Oracle
documentation site.
4. Delete the RAC database software and Oracle Clusterware.
For more information on deleting the RAC database and Oracle Clusterware, see the
documentation available at the Oracle documentation site.
5. Remove the node from the node list of the Site Controller Package.
6. To stop the cluster on this node, type the following command: cmhaltnode
7. Remove the node from the cluster configuration.
For more information on removing a node from the cluster configuration, see the Managing
Serviceguard manual available at http://www.hp.com/go/hpux-serviceguard-docs.
Deleting nodes online on the site where the RAC database package stack is down
To delete nodes online on the site where the RAC database package stack is down:
1. Remove the RAC MNP package instance configuration on the node that must be deleted.
2. Remove access to RAC database storage from this node by removing the storage configuration.
For more information on removing access to the RAC database storage device, see the CFS,
CVM, and SLVM documentation.
3. To clear the registration of the RAC database instance with the CRS subcluster on the site,
type the following command:
# srvctl remove instance -i hrdb3 –d hrdb
4. Remove the tnsnames.ora entry for the instance being deleted on all nodes in the site.
5. Remove Oracle RAC and Oracle Clusterware software on the node.
For more information on removing Oracle RAC and Oracle Clusterware, see the Oracle
Database 10gR2 RAC documentation available at the Oracle documentation site.
6. Remove the node from the node list of the Site Controller Package.
7. Halt the cluster on this node, run the following command: cmhaltnode.
8. Remove the node from the cluster configuration.
For more information on removing nodes from the cluster configuration, see the Managing
Serviceguard manual.
9. Start the Site Controller Package.
