You can install Oracle Database software binaries on a local file system to enable the Oracle Database Standard Edition high availability feature.

1. As the Administrator user, log into the first cluster node on which you want to configure Standard Edition High Availability and create the Oracle base directory on the local file system. Follow the Oracle Optimal Flexible Architecture (OFA) recommendations and specify the correct owner, group, and permissions for this directory.

   C:\>md C:\app\oracle
   C:\>icacls oracle:oinstall C:\app\oracle

2. Log in to the first cluster node as the Oracle Database software owner user (oracle).
3. Download the Oracle Database 19c release 19.3 installation image file (db_home.zip) from Oracle Software Delivery Cloud website to a directory of your choice.

   https://edelivery.oracle.com/

4. Download the Oracle Database Release Update 19.7 or later patch from My Oracle Support to a directory of your choice and unzip it.

   https://support.oracle.com/

5. Create an OFA-compliant Oracle home directory on the local file system and extract the image files that you have downloaded in to this Oracle home directory. For example:

   C:\>md C:\app\oracle\product\19.0.0\dbhome_1
   C:\>cd C:\app\oracle\product\19.0.0\dbhome_1
   C:\app\oracle\product\19.0.0\dbhome_1> unzip \tmp\db_home.zip

6. From the Oracle home directory, run the setup.exe command to start the Oracle Database Setup Wizard.

   C:\app\oracle\product\19.0.0\dbhome_1>setup.exe

   Note:

   Run the setup.exe command from the Oracle home directory only. Do not use the setup.exe command that resides at %ORACLE_HOME%\oui\bin\, or any other location, to install Oracle Database.
7. In the Select Configuration Option screen, select Set Up Software Only.
8. In the Select Database Installation Option screen, select Single instance database installation.
9. In the Select Database Edition screen, select Standard Edition 2.
10. Respond to the configuration prompts as needed.

    Note:

    Click Help if you have any questions about the information you are asked to submit during installation.
11. Apply the Oracle Database Release Update (RU) 19.7 or later patch. Review the patch documentation for instructions on how to apply the patch.

    Note:

    Ensure that you apply the Oracle Clusterware (OCW) RU of the same version to the Oracle Database home.

12. Optional: As the oracle user, enable read-only Oracle home on the first cluster node.

    cd C:\app\vldb22\product\19.0.0\dbhome_1\bin
    C:\app\vldb22\product\19.0.0\dbhome_1\bin>roohctl.bat -enable

    Note:

    Do not use the -disable flag with the roohctl command, as it is not supported.
13. As the Administrator user, create the Oracle base directory on all of the other cluster nodes on which you want to configure Standard Edition High Availability.

    C:\>md C:\app\oracle
    C:\>icacls oracle:oinstall C:\app\oracle

14. As the oracle user, run the addnode.bat script from the first node to perform the following operations on the other nodes on which you want to configure Standard Edition High Availability:
    • Copy the Oracle home directory from the first node to the other nodes.
    • Setup Oracle base, Oracle inventory directories, and Oracle DB registry keys on the other nodes.

    C:\>%ORACLE_HOME%\addnode\addnode.bat -silent CLUSTER_NEW_NODES=comma_separated_list_of_other_nodes

15. If you specify a non built-in and a non Administrator's user account while installing Oracle Database, then add the respective user's password to the CRS wallet using the following command:

    crsctl add wallet -type OSUSER -user DB service user name -password
