Installing the New Oracle Database Software for Oracle RAC

Use this procedure overview to assist you to install the software for the new Oracle Database release for an Oracle RAC .deployment.


You cannot upgrade a database using Database Upgrade Assistant (DBUA) when the source and target Oracle homes are owned by different users. Attempting to do so returns error PRKH-1014. Either ensure that the source and target databases have the same owner, or perform a manual upgrade.

If you are upgrading an Oracle RAC database, then you must perform the following steps in the order shown:

  1. Upgrade Oracle Clusterware:

    1. Upgrade Oracle Clusterware first as described in the Oracle Grid Infrastructure installation guide for your operating system.

    2. Mount the Oracle Grid Infrastructure installation media.

    3. Perform operating system prerequisite checks on each of the nodes that you intend to upgrade, to ensure that they meet the system prerequisites for Oracle Grid Infrastructure (Oracle Clusterware and Oracle ASM).

    4. If necessary, perform patch upgrades of the earlier release of Oracle Clusterware software to the most recent patch version.

    5. Ensure that you are logged in as the user that owns the Oracle Grid Infrastructure installation, and run the Oracle Grid Infrastructure installation. Provide information as prompted by the installer.

    6. When prompted, open a separate terminal session, log in as root, and run

  2. After upgrading Oracle Clusterware, follow the instructions in your Oracle operating system-specific documentation to prepare for Oracle Database software installation.

  3. Run the Pre-Upgrade Information Tool. You can preview the types of items DBUA checks, and identify issues. The Pre-Upgrade Information Tool can help you fix some of the prerequisite issues that it finds.

  4. Start Oracle Universal Installer, and install the software.

    When installation of Oracle Database software has completed successfully, click Exit to close Oracle Universal Installer.

  5. Run DBUA.

    If you use Oracle Label Security, Oracle Database Vault, or both, then select Enterprise Edition on the Select Database Edition page, click Select Options, and enable one or both components from the components list.
