The certified Oracle database 19c version for Red Hat Enterprise Linux 8+ is Oracle Enterprise Edition 19.0.0.0 at minimum RU 19.7 (or 19.6 with patches) with minimum kernel version 4.18.0-80.el8.x86_64 or later. For more information, see Oracle Database 19.0.0.0. certification on Linux 86-64 Red Hat Enterprise Linux 8. In accordance with the Oracle certification, this solution uses Red Hat Enterprise Linux 8.2 with kernel version 4.18.0-193.el8.x86_64 for the guest operating system of the database VMs and Oracle RAC Enterprise Edition 19cRU7 for the Oracle RAC database.   

The Oracle 19cRU7 stack consists of Oracle GI 19cRU7 and Oracle RAC 19cRU7. Because the base versions of Oracle GI 19c software and Oracle RAC database 19c software were released with the Red Hat Enterprise Linux 8.x certification, apply patches to both Oracle GI 19c and Oracle RAC 19c to install both GI 19c software and RAC 19c software and upgrade them to 19cRU7.

The following table shows these software patches and their corresponding Oracle support document IDs:

Install Oracle GI 19cRU7

To install and configure Oracle GI 19cRU7 on the two database nodes:

1. Extract LINUX.X64_193000_grid_home.zip in the first database node.
2. Set the operating system environment variable $CV_ASSUME_DISTID=OL7 and install the Oracle GI 19c base version to the Oracle GI home of the first node by running: $gridSetup.sh.
3. Apply patch 6880880 to the Oracle GI home to upgrade the Opatch utility from 12_2.0.1.17 to 12.2.0.1.19.
4. Apply patch p30189609 to the Oracle GI home for bug 30189609.8: cvu fails to detect the passwordless ssh and to set up passwordless SSH connectivity.
5. Extract the p30783556_190000_Linux-x86-64.zip combination patch, which includes both the 30899722 and 30805684 patches. Apply patch 30899722 to the Oracle GI 19c home to upgrade it from the 19c base version to 19cRU7 by following the instructions in Doc ID 30899722.8.
6. Install and configure the upgraded Oracle GI 19cRU7 by running the following command: $gridSetup.sh

7. Click Configure Oracle Grid Infrastructure for a New Cluster and select both nodes.
8. If you continue to experience the error [INS-06003} Failed to setup passwordless SSH connectivity, create the passwordless SSH manually by running a command such as:

$ORACLH_HOME/deinstall/sshUserSetup.sh -user grid -hosts "hostname1 hostname2" " -noPromptPassphrase -confirm -advanced

The dialog shown in the following figure appears:

9. Select Reuse private and public keys existing in the user home and click Setup to set up the passwordless SSH connectivity:

This selection lasts through the remainder of the Oracle GI 19cRU7 installation and configuration.

Install Oracle RAC 19cRU7

To install and configure Oracle RAC 19cRU7:

1. After extracting Oracle RAC 19c base version, install the base software by setting the environment variable $export CV_ASSUME_DISTID=OL7 and running the runInstaller command.

2. During the SSH connectivity check phase, if you experience an error message such as [INS-30132] Initial setup required for the execution of Installer validation failed on nodes: node2, manually create the passwordless SSH connectivity by running a command such as:

$ORACLE_HOME/deinstall//sshUserSetup.sh -user oracle -hosts "node11 node2" -noPromptPassphrase -confirm -advanced

The following dialog is displayed:

3. Select Reuse private and public keys existing in the user home and click Test.

The following message is displayed:

4. Click OK and continue with the Oracle RAC software installation.
5. Follow the instructions in the patch 6880880 readme file to apply the patch the Oracle RAC home on each RAC node to upgrade the Opatch utility from 12_2.0.1.17 to 12.2.0.1.19.
6. Apply the patch to upgrade the Oracle RAC home from 19c base version to 19cRU7 by following the instructions in Oracle Support Document 30899722.8. Run the opatchauto command as the Linux root user on each RAC node.
7. Follow the instructions in the 30805684 readme file to apply the patch to Oracle RAC home on each node.
