Creating SCAN Client Data File

Generate a SCAN client data file and copy the file to the SCAN client cluster member node on which you are installing Oracle Grid Infrastructure.

1. As the grid user, create a SCAN listener that is exclusive to this shared SCAN cluster.

   $ srvctl add scan_listener -clientcluster cluster_name

2. As the root user, create a new Oracle Notification Service (ONS) resource that is specific to the server cluster.

   # srvctl add ons -clientcluster cluster_name

   The srvctl add ons command assigns an ID to the SCAN.

3. As the grid user, export the SCAN listener to the client cluster.

   $ srvctl export scan_listener -clientcluster cluster_name -clientdata file_name

4. Export the ONS resource to the client cluster.

   $ srvctl export ons -clientcluster cluster_name -clientdata file_name

5. Modify the SCAN listener configuration.

   $ srvctl modify scan_listener -clientcluster cluster_name -invitednodes new_cluster_nodes -update

6. Start the SCAN listener.

   $ srvctl start scan_listener -clientcluster cluster_name
