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

Storage Management Requirements

Decide which storage management scheme to use:

• VERITAS Volume Manager (VxVM) with the cluster feature

• Hardware redundant array of independent disks (RAID) support

• The cluster file system

  If you use the cluster file system, decide which volume manager to use:

  • Solaris Volume Manager

  • VxVM without the cluster feature

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 abort.

For example, if you use 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 Parallel Server/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 environment, Sun Cluster, Oracle, and your volume manager. 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.
