I thought, 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?
- It creates the inventory pointer file (/etc/oraInst.loc)
- 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?
- It will set the environment variable for ORACLE_HOME and ORACLE_OWNER
- Copy dbhome,oraenv,coraenv to /usr/local/bin
- Creates the /etc/oratab file
- Verify the super user privileges for the user.
- Creating the trace directory
- Creates OCR keys for the 'root' user
- Adding clusterware Daemon information to inittab file
- Starts Oracle High Availability service Daemon(OHASD) service
- Start the clusterware daemons(gipcd,mdnsd,gpnpd,cssmonitor,cssd,diskmon,ctssd etc)
- Creates and configures an ASM instance and ASM disk group will be created.
- Creates required ASM disk groups, if ASM is being used to put OCR and voting files.
- It Configures the OCR and voting disks (only on the first node)
- Starts up the Cluster Ready Service Daemon (CRSD) process
- updating the profile by adding voting disk
- It Puts the voting disk on the ASM disk group ,if ASM type is selected.
- It Displays voting disk details
- Attempting to stop and start the cluster resources(crsd,asm, ctssd,cssmonitor, cssd,gpnpd, gipcd etc)
- updates the OLR files
- Installs the cvuqdisk-1.0.7-1 package
- Configure Oracle Grid Infrastructure for Cluster
- Updating inventory properties for clusterware
- Starts the Oracle universal Installer
- Check the swapspace and make sure we have enough space
- Completes with the UpdateNodeList success operation.
The log is from first node.
