About Oracle Grid Infrastructure Dry-Run Upgrade Mode

Oracle Grid Infrastructure dry-run upgrade mode enables you to check system readiness for upgrade.

Starting with Oracle Grid Infrastructure 19c, the Oracle Grid Infrastructure installer enables you to perform a dry-run upgrade to check readiness of the system for upgrade. To perform Oracle Grid Infrastructure dry-run upgrade, create a new Grid home with the necessary user group permissions, extract the Oracle Grid Infrastructure 21c gold image to the new Grid home, and then start the installer with —dryRunForUpgrade flag.

Dry-run upgrades are not supported on Oracle Grid Infrastructure for a standalone server (Oracle Restart) configurations.

Note:

The installer does not perform an actual upgrade in the dry-run upgrade mode. You can relaunch the installer, without any flag, from any of the cluster nodes to upgrade Oracle Grid Infrastructure if dry-run is successful.
The installer performs the following tasks in dry-run upgrade mode:
  • Validates storage and network configuration for the new release

  • Checks if the system meets the software and hardware requirements for the new release

  • Checks for the patch requirements and apply necessary patches before starting the upgrade

  • Writes system configuration issues or errors in the gridSetupActions<timestamp>.log log file

The Grid infrastructure dry-run upgrade flow is similar to a regular upgrade, but the installer does not run any configuration tool.
