Before you begin the installation, note the hardware and software requirements in the subsections that follow.
For information about supported versions, see http://www.oracle.com/technetwork/server-storage/solaris-cluster/overview/solariscluster4-compatibilityguide-1429037.pdfOracle Solaris Cluster 4 Compatibility Guide (login to My Oracle Support required).
Support for Oracle RAC requires a functioning cluster with the initial cluster framework already installed. See Oracle Solaris Cluster Software Installation Guide for details about initial installation of cluster software.
If you will use Oracle Grid Infrastructure (Oracle ASM and Oracle Clusterware), ensure that the cluster meets Oracle Grid Infrastructure software requirements. See the information about configuring operating systems in the Oracle Grid Infrastructure Installation Guide for your version of Oracle Grid Infrastructure software.
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.
Check with an Oracle service representative for the current supported topologies for Support for Oracle RAC, cluster interconnect, storage management scheme, and hardware configurations.
Ensure that you have installed all the applicable software updates for the Oracle Solaris OS, Oracle Solaris Cluster, Oracle Database, and volume manager software. If you need to install any Support for Oracle RAC software updates, you must apply these updates after you install the data service packages.
