2.13.1 Adding a New Database Server to the Cluster

You can add a new database server to an existing Oracle Real Application Clusters (Oracle RAC) cluster running on Oracle Exadata.

1. Determine if the new database server needs to be re-imaged or upgraded.

   Check the image label of the database servers in the cluster to which you want to add the new database server.

   • If the image label of the new database server is later, or a newer release, than the image label of the existing database servers in the cluster and you do not wish to upgrade the existing servers, then reimage the new database server to the older version by completing the following tasks:

     • Download Latest Release of Cluster Verification Utility
     • Image the Database Server
     • Configure the Re-imaged Database Server

   • If the image label of the new database server is earlier, or an older release, than the image label of the existing database servers in the cluster, then an upgrade is required using patchmgr. See Updating Exadata Software for details.

2. Add the database server to the cluster by completing the following tasks:

   • For bare metal systems:

     • Prepare the Re-imaged Database Server for the Cluster
     • Clone Oracle Grid Infrastructure to the Replacement Database Server
     • Clone Oracle Database Homes to the Replacement Database Server

   • For Oracle VM systems:

     • Expanding an Oracle RAC Cluster on Oracle VM Using OEDACLI
3. Download and run the latest version of Exachk to ensure that the resulting configuration implements the latest best practices for Oracle Exadata.
