Pre-Installation Considerations

Before you begin the installation, note the following pre-installation considerations.

• Sun Cluster Support for Oracle Parallel Server/Real Application Clusters requires a functioning cluster with the initial cluster framework already installed. See the Sun Cluster 3.1 Software Installation Guide for details about initial installation of cluster software.

• Decide which volume manager you will use—either VERITAS Volume Manager (VxVM) or RAID Manager.

• Verify that you have obtained the appropriate licenses for your software. If, for example, you use VxVM, run the vxlicense -p check command to ensure that you have installed a valid license for the Volume Manager cluster feature. If you install your licenses incorrectly or incompletely, the nodes might abort.

• Check with a Sun Enterprise Services representative for the current supported topologies for Sun Cluster Support for Oracle Parallel Server/Real Application Clusters, cluster interconnect, volume manager, and hardware configurations.

• Ensure that you have installed all of the applicable software patches for Solaris, Sun Cluster, Oracle, and your volume manager. The Oracle UDLM consists of two packages—ORCLudlm, which Oracle supplies, and SUNWudlm, which Sun supplies. You must install both of these packages. If you need to install any Sun Cluster Support for Oracle Parallel Server/Real Application Clusters patches, you must apply these patches after you install the data service.

• You should install the Oracle binaries locally on each node in the cluster, rather than globally on the cluster file system, to avoid overwrite issues with configuration files and logs. However, if you plan to install the Oracle binaries on the cluster file system, contact Oracle to validate the support of this configuration. Additionally, see the Oracle documentation for configuration specifics.
