Installing SF Oracle RAC on the secondary site

Important requirements for global clustering:

• Cluster names on the primary and secondary sites must be unique.
• Node and resource names must be unique within a cluster but not across clusters.

You can set up a multi-node or single-node cluster on the secondary site. The only difference between setting up a single node-cluster and a multi-node cluster is the fencing configuration.

Installing SF Oracle RAC on a multi-node cluster

If you install SF Oracle RAC on a multi-node cluster on the secondary site, you can enable I/O fencing feature of SF Oracle RAC.

 To install SF Oracle RAC on a multi-node cluster

1. Prepare to install SF Oracle RAC by planning your installation, reviewing the requirements, and performing pre-installation tasks.

   See Planning SF Oracle RAC installation and configuration

   See Preparing to install and configure SF Oracle RAC

2. Install SF Oracle RAC.
   • Global clustering requires different names for the clusters on the primary and secondary sites.
   • To install a multi-node cluster:

     See Installing and configuring SF Oracle RAC components

3. Set up storage on the secondary site and configure I/O fencing.
   • Verify that the shared storage on the secondary site supports SCSI-3 reservations.
   • Set up the coordinator disks.
   • Configure I/O fencing for multi-node clusters.
   • Update the main.cf file on the secondary site.

     See Setting up I/O fencing for SF Oracle RAC

4. Shut down and restart all nodes on the secondary site.
5. After starting the cluster nodes, check that the cvm group is online:

   # hagrp -state cvm

Installing SF Oracle RAC on a single-node cluster

For a single-node cluster, after installing and configuring SF Oracle RAC, do not enable I/O fencing. You must not create a coordinator disk group and edit the configuration files to enable fencing. Fencing will run in disabled mode.

If you add more nodes later to the existing single-node cluster on the secondary site, then you must enable I/O fencing.

 To install SF Oracle RAC on a one-node cluster

1. Prepare to install SF Oracle RAC by planning your installation, reviewing the requirements, and performing pre-installation tasks.

2. Install SF Oracle RAC.
   • Global clustering requires different names for the clusters on the primary and secondary sites.
   • To install a single-node cluster on the secondary site:

3. Set up storage on the secondary site.
4. Shut down and restart the node on the secondary site.
5. After starting the cluster node, check the cvm group is online:

   # hagrp -state cvm
