Testing the 19c Grid Infrastructure by Performing a Dry-Run Upgrade

Editor’s Note: Because our bloggers have lots of useful tips, every now and then we update and bring forward a popular post from the past. We originally published today’s post on August 14, 2019. In reviewing the
Grid Infrastructure Installation and Upgrade Guide for Linux, I discovered the dry-run upgrade mode to test upgrades. With dry-run being a new feature, I tested it first using GUI. Below I will step you through this process:

[oracle@racnode-dc2-1 GridSetupActions2019-08-06_02-35-52AM]$Since I have not performed an actual upgrade, I don't know if 19.3.0.0 grid home in oraInventory will be problematic. It was problematic when performing a test with silent mode after the initial test with GUI. To resolve the issue, you can detach 19.3.0.0 grid home.
export ORACLE_HOME=/u01/app/19.3.0.0/grid $ORACLE_HOME/oui/bin/runInstaller -detachHome -silent ORACLE_HOME=$ORACLE_HOMEIn conclusion, testing a grid upgrade using dryRunForUpgrade functionality is a good method to identify any possible issues before performing an actual upgrade.
