Chapter 4. RHEL System Roles for SAP

Procedure

1. Make a backup of the system if you would like to preserve the original configuration of the server.
2. Configure your name resolution and /etc/hosts settings according to your desired configuration. The RHEL System Roles for SAP can also be used to maintain your /etc/hosts file (using the parameters sap_domain and sap_general_preconfigure_modify_etc_hosts) but for simplicity, we assume that your name resolution and the content of /etc/hosts are configured already.
3. Ensure that your release lock is set according to your needs and that you have enabled the desired repositories. The RHEL System Roles for SAP can also be used to set the release lock and enable the repos but for simplicity, we assume that these configuration settings are already done.

4. Create a file named sap-vars.yml with the content in the code block below. It updates your system to the latest patch level. If this is not desired, set sap_general_preconfigure_update and sap_hana_preconfigure_update to false, comment out these lines by prepending them with #, or remove these two lines:

   ---
   
   sap_general_preconfigure_update: true
   sap_general_preconfigure_fail_if_reboot_required: false
   sap_netweaver_preconfigure_fail_if_reboot_required: false
   sap_hana_preconfigure_update: true
   sap_hana_preconfigure_fail_if_reboot_required: false

5. Run the following command:

   # ansible-playbook redhat.sap_install.sap_hana_preconfigure_exec.yml -e @sap-vars.yml

   This configures this system according to the applicable SAP notes for SAP HANA on RHEL 10.

6. After the ansible-playbook command has finished, reboot the system:

   # reboot

5. Create a file named sap-abap.yml with the following content:

   ---
   
   - hosts: localhost
     collections:
       - redhat.sap_install
     become: true
     roles:
       - sap_general_preconfigure
       - sap_netweaver_preconfigure

6. Run the following command:

   # ansible-playbook sap-abap.yml -e @sap-vars.yml

   This configures this system according to the applicable SAP notes for SAP HANA on RHEL 10.

   - hosts: localhost

     become: true
     roles:
       - sap_general_preconfigure
       - sap_netweaver_preconfigure
       - sap_hana_preconfigure

6. Run the following command:

   # ansible-playbook sap-hana_abap.yml -e @sap-vars.yml

   This configures this system according to the applicable SAP notes for SAP HANA on RHEL 10. Run the role sap_hana_preconfigure after the role sap_netweaver_preconfigure to ensure the configuration of certain specific settings for SAP HANA (e.g. kernel tunables).

7. After the ansible-playbook command has finished, reboot the system:

   # reboot
