Installing Oracle Real Application Clusters

	NOTE: Some versions of Oracle RAC requires installation of additional software. Refer to your version of Oracle for specific requirements.

Before installing the Oracle Real Application Cluster software, make sure the cluster is running. Log in as the oracle user on one node and then use the Oracle installer to install Oracle software and to build the correct Oracle runtime executables. The Oracle installer also copies the executables to the other nodes in the cluster. Select the following installation option to install RAC software and to create the demo database:

COMPLETE SOFTWARE/DATABASE FRESH INSTALL

Refer to your Oracle installation documentation for Oracle installation details. As part of this installation, the Oracle installer builds the Oracle demo database on the primary node, using the character (raw) device file names for the logical volumes created earlier. For the demo database, create fourteen logical volumes as shown in the table “Table 2-1 “Required Oracle File Names for Demo Database ”” earlier in this chapter. As the installer prompts for database file names, enter the pathnames of the raw logical volumes instead of using the defaults. If you do not wish to install the demo database, select:

SOFTWARE INSTALL ONLY

In this case, create an appropriate number of raw logical volumes to build your development or production system. Be sure to create enough log files for all instances.
