What does root.sh perform on RAC Cluster Installation

It may be useful for others to understand what actions are being performed while running root.sh on RAC cluster installation. I spend some time today and update this topic on my blog for every one benefit 

 

At the end of the RAC cluster installation,  we run root.sh and orainstRoot.sh file.  

 

You will see this screen right before the installation completion.  Please note, i captured this screen on 11.2.0 installation. But oracle12c. you may not see this screen and GUI tool will run the root,.sh. 

What does orainstRoot.sh perform?

 

1.                It creates the inventory pointer file (/etc/oraInst.loc)

2.                It Changes groupname of the oraInventory directory to oinstall group.

 

The log is from first node.

 

[root@RAC1 grid]# sh /grid/app/oraInventory/orainstRoot.sh Changing permissions of /grid/app/oraInventory. Adding read,write permissions for group. Removing read,write,execute permissions for world. Changing groupname of /grid/app/oraInventory to oinstall. The execution of the script is complete. [root@RAC1 grid]#

 

 

 

 What does Root.sh perform?  

1.                It will set the environment variable for ORACLE_HOME and ORACLE_OWNER

2.                Copy dbhome, oraenv, coraenv to /usr/local/bin

3.                Creates the /etc/oratab file

4.                Verify the super user privileges for the user.

5.                Creating the trace directory

6.                Creates  OCR keys for the 'root' user

7.                Adding clusterware Daemon information  to inittab file

8.                Starts Oracle High Availability service Daemon(OHASD) service

9.                Start the clusterware daemons(gipcd, mdnsd, gpnpd, cssmonitor, cssd, diskmon,ctssd etc)

10.             Creates and configures an ASM instance and ASM disk group will be created.

11.             Creates required ASM disk groups, if ASM is being used to put OCR and voting files.

12.             It Configures the OCR and voting disks (only on the first node)

13.             Starts up the Cluster Ready Service Daemon (CRSD) process

14.             updating the profile by adding voting disk

15.             It Puts the voting disk on the ASM disk group ,if ASM type is selected.

16.             It Displays voting disk details

17.             Attempting to stop and start the cluster resources(crsd,asm, ctssd,cssmonitor, cssd,gpnpd, gipcd etc)

18.             updates the OLR files

19.             Installs the cvuqdisk-1.0.7-1 package

20.             Configure Oracle Grid Infrastructure for Cluster

21.             Updating inventory properties for clusterware

22.             Starts the Oracle universal Installer

23.             Check the swapspace and make sure we have enough space

24.             Completes with the UpdateNodeList success operation.
