Hardware and Software Requirements

Before you begin the installation, note the hardware and software requirements in the subsections that follow.

Sun Cluster Framework Requirements

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

Storage Management Requirements for the Oracle Real Application Clusters Database

You must configure Oracle Real Application Clusters to use the shared-disk architecture of the Sun Cluster software. In this configuration, a single database is shared among multiple instances of the Oracle Real Application Clusters software that access the database concurrently. The UNIX Distributed Lock Manager (Oracle UDLM) controls access to shared resources between cluster nodes.

To satisfy these requirements, use one storage management scheme from the following list:

• Solaris Volume Manager for Sun Cluster

  ---

  Note –

  Solaris Volume Manager for Sun Cluster is supported only with Oracle Real Application Clusters. Solaris Volume Manager for Sun Cluster with Oracle Parallel Server is not supported.

  ---

• VERITAS Volume Manager (VxVM) with the cluster feature

• Hardware redundant array of independent disks (RAID) support

• Sun StorEdge^TM QFS shared file system with hardware RAID support

Software License Requirements

Verify that you have obtained and installed the appropriate licenses for your software. If you install your licenses incorrectly or incompletely, the nodes might fail to boot correctly.

For example, if you are using VxVM with the cluster feature, verify that you have installed a valid license for the Volume Manager cluster feature by running one of the following commands:

• For versions of VxVM earlier than 3.5, run the vxlicense -p command.

• For VxVM version 3.5, run the vxlicrep command.

Supported Topology Requirements

Check with a Sun Enterprise Services representative for the current supported topologies for Sun Cluster Support for Oracle Real Application Clusters, cluster interconnect, storage management scheme, and hardware configurations.

Patch Installation Requirements

Ensure that you have installed all of the applicable software patches for the Solaris Operating System, Sun Cluster, Oracle, and your volume manager. If you need to install any Sun Cluster Support for Oracle Real Application Clusters patches, you must apply these patches after you install the data service packages.
