Chapter 3. Completing post-installation tasks This section describes how to complete the post-installation tasks. 3.1. Registering your system This section explains how to register your RHEL server to Red Hat Satellite. Note Different steps apply if your system is registered to the Red Hat Customer Portal or your Cloud provider. Prerequisites You must have a valid Red Hat Enterprise Linux for SAP Solutions subscription so your server has access to required packages via a Red Hat Satellite server, the Red Hat Customer Portal, or your Cloud provider. You must have the following information provided to you by your Satellite administrator: An activation key. A string representing the name of the organization. A URL for the Katello client package. You have system administrator access. Procedure Download the Katello client rpm package: Replace the URL with the URL provided by your Satellite administrator. Install the Katello client rpm package: Replace the package name with the name of the package you downloaded. Register your system: Replace your-organization-name with the string representing the name of the organization and replace your-activation-key with the activation key. Both are provided by your Satellite administrator. 3.2. Applying the RHEL release lock For RHEL systems running the SAP HANA database, it is essential that you set the RHEL release lock so that the system remains on the correct RHEL minor release even when doing package updates. Otherwise, the system might be updated to a RHEL release which is not supported by SAP. For RHEL systems not running the SAP HANA database, any RHEL 9 minor release can be used, so applying the RHEL release lock is not necessary in this case. Prerequisites You have system administrator access. Procedure Clear the dnf cache: Set the release lock: Replace 9.x with the supported minor release of RHEL 9 (for example 9.4 ). Additional resources How to tie a system to a specific update of RHEL 3.3. Enabling required repositories You need to enable certain RHEL repositories to have access to packages required for the SAP HANA installation. For more information on which repositories to enable, see RHEL for SAP Subscriptions and Repositories . Prerequisites You have system administrator access. Procedure Disable all repositories and enable the required ones. For systems running the SAP HANA database, enable the e4s repos after ensuring that the RHEL release lock is set properly (example for RHEL 9.4): Note If you intend to use the system for the SAP HANA database only, enabling the sap-netweaver-e4s-rpms repository is not required. For systems running the SAP Application Platform only, if you do not want to restrict your system to a specific RHEL minor release when updating packages, enable the normal repos. In this case, verify that no RHEL release lock is set. Additional resources How to Subscribe to Update Services for SAP Solutions on RHEL 8 and RHEL 9
