Testing The 19c Grid Infrastructure By Performing A Dry-Run Upgrade

In reviewing 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.

[oracle@racnode-dc2-1 grid]$ /u01/app/19.3.0.0/grid/gridSetup.sh -dryRunForUpgrade

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 initial test with GUI. To resolve the issue, 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_HOME

In conclusion, testing grid upgrade using dryRunForUpgrade functionality is a good method to identify any possible issues before performing an actual upgrade.
