  Oracle Database Tips by Donald Burleson

Oracle10g Grid Computing with RAC
Chapter 6 - Install, Configure and Database Creation

CRS Installation

If you are installing CRS on a node that already has a single-instance Oracle Database 10g installation, and the ASM instance is running, stop the ASM and CSS daemon by running the $ORACLE_HOME/bin/localconfig delete in the home that is running Cluster Synchronization Services (CSS) to reset the OCR configuration information. 

After CRS is installed, then start up the ASM instances again and the ASM instances will use the cluster CSS daemon instead of the earlier daemon of the single-instance Oracle database. The following steps describe the CRS installation process.

  1. Launch the Oracle Universal Installer by using runInstaller command from the /crs subdirectory on the Oracle Cluster Ready Services Release 1 ( CDROM. A welcome page is displayed as shown below:

  1. Next, Select the inventory directory and specify the operating system group name, which is usually the 'dba'. Then you will be prompted to execute the script with root privilege as shown in Fig. 6.6
