2024-12-17 06:53:48

Grid Installation Package

Unzip the Grid installation package to the /u01/app/grid_home/ directory and refresh the file properties in the grid_home/ directory.

cd /u01/app/grid_home/unzip   LINUX.X64_193000_grid_home.zipcd ..chown -R grid:oinstall   grid_home/    

After performing the preceding basic operations on the instance, some configurations may still be missed. You can use the check script available in the Oracle database to check dependencies and troubleshoot important issues.

Network Connectivity Check

After switching to the Grid user, switch to the /u01/app/grid_home directory and run the following command:

[grid@rac-node01   grid_home]$ ./runcluvfy.sh comp nodecon -n rac-node01,rac-node02-verbose    

You can proceed with your operations only when the result indicates that the node connectivity is successfully checked.

Basic Dependency Check

After switching to the Grid user, switch to the /u01/app/grid_home directory and run the following command:

[grid@rac-node01   grid_home]$ ./runcluvfy.sh stage -pre crsinst -n rac-node01,rac-node02    

Error items may exist in the check result. You can take corrective measures to eliminate errors against the result. Common errors are shown as below:

l   The installation package is missed. In this case, you must use cv/rpm/cvuqdisk-1.0.10-1.rpm in the yum or grid_home directory to install the missing dependency package.

l   Failed to check the kernel parameter configuration. In this case, you must modify the corresponding kernel parameter configuration.
