Run the Oracle Grid Infrastructure installer in dry-run upgrade mode to determine if the system is ready for upgrade.

1. As grid user, download the Oracle Grid Infrastructure image file and extract the file to the Grid home.

   For example:

   $ mkdir -p /u01/app/19.0.0/grid
   $ chown grid:oinstall /u01/app/19.0.0/grid
   $ cd /u01/app/19.0.0/grid
   $ unzip -q download_location/grid_home.zip

   download_location/grid_home.zip is the path of the downloaded Oracle Grid Infrastructure image file.

   Note:

   You must extract the image file into the directory where you want your Grid home to be located.

2. Start the Oracle Grid Infrastructure installation wizard in dry-run upgrade mode by running the following command:

   $ /u01/app/19.0.0/grid/gridSetup.sh -dryRunForUpgrade

3. Select Upgrade Oracle Grid Infrastructure option to perform dry-run upgrade for Oracle Grid Infrastructure (Oracle Clusterware and Oracle ASM).
4. On the Node Selection page, select all nodes.
5. Select installation options as prompted. Oracle recommends that you configure root script automation, so that the rootupgrade.sh script can be run automatically during the dry-run upgrade.
6. Run root scripts, either automatically or manually:
   • Running root scripts automatically:

     If you have configured root script automation, then the installer will run the rootupgrade.sh script automatically on the local node.

   • Running root scripts manually

     If you have not configured root script automation, then when prompted, run the rootupgrade.sh script on the local node.

   If you run root scripts manually, then run the script only on the local node.
7. Check the gridSetupActions<timestamp>.log log file for errors and fix errors reported in the log file.
8. Exit the installer on the Finish screen and relaunch it without any flag to start an actual upgrade.
