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 grid]$ /u01/app/ -dryRunForUpgrade

 You can find the log of this install session at:
 [oracle@racnode-dc2-1 grid]$
From the response file above grid_2019-08-06_00-20-31AM.rsp, create dryRunForUpgradegrid.rsp:
[oracle@racnode-dc2-1 grid]$ grep -v "^#" /u01/app/ | grep -v "=$" | awk 'NF' > /home/oracle/dryRunForUpgradegrid.rsp
 [oracle@racnode-dc2-1 ~]$ cat /home/oracle/dryRunForUpgradegrid.rsp
 [oracle@racnode-dc2-1 ~]$
Next, create directory /u01/app/ for all nodes:
[root@racnode-dc2-1 ~]# id oracle

Then, check oraInventory for ALL nodes:

Since I have not performed an actual upgrade, I don't know if 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 grid home.
export ORACLE_HOME=/u01/app/
 $ORACLE_HOME/oui/bin/runInstaller -detachHome -silent ORACLE_HOME=$ORACLE_HOME
In conclusion, testing a grid upgrade using dryRunForUpgrade functionality is a good method to identify any possible issues before performing an actual upgrade.
