Execute four scripts and their meanings during RAC Installation

Execute four scripts during RAC installation.

1) $ ORACLE_BASE/oraInventory/orainstRoot. sh (executed when clusterware ends)

2) $ CRS_HOME/root. sh (executed when clusterware ends)

3) $ CRS_HOME/bin/vipca. sh (this script is automatically called when $ CRS_HOME/root. sh is executed on the second node)

4) $ ORACLE_HOME/root. sh (executed after the database is installed)

From the script, we can see that this script mainly creates the/var/opt/oracle directory (if it does not exist), and then creates oraInst under this directory. loc file (this file records the location and group of orainventory ). And change the attributes of orainventory.
