Automated operating system patching prerequisites

In addition to the prerequisites described in the Automation prerequisites section of this guide, verify the following prerequisites that are specific to automated operating system patching:

  • Verify the Patch Manager prerequisites.

    Because the solution described here uses AWS Systems Manager Patch Manager, you must verify that you have satisfied all of the Patch Manager prerequisites. For more information, see Patch Manager prerequisites in the AWS Systems Manager User Guide.

  • Ensure you have a backup of your SAP system.

    Before you make changes to the SAP system, verify that a backup is available to support rollback in case you encounter problems. You should have the following backups:

    • Operating system backup – You should have an Amazon Machine Image (AMI) backup of the Amazon EC2 instance that consists of the base operating file system (root for Linux and C:\ for Microsoft Windows) and the SAP application and database file systems.

    • Database backup – If patching will occur on the database server, ensure you have the most recent database backup.

    For data recovery recommendations, see Plan for data recovery in the SAP Lens AWS Well-Architected Framework.

Supported operating systems

The following operating systems are supported by SAP and Patch Manager. Check the Patch Manager prerequisites for currently supported versions of the operating systems. For more information, see Patch Manager prerequisites in the AWS Systems Manager User Guide.

  • Oracle Linux

    Note

    Oracle Linux is required if you are running an Oracle database.

  • Red Hat Enterprise Linux (RHEL)

  • SUSE Linux Enterprise Server (SLES)

  • Microsoft Windows Server

Note

  • SUSE Linux and Red Hat Linux have SAP versions of the Linux operating system. SAP recommends that you use RHEL for SAP Solutions/Applications or SLES for SAP Applications to run the SAP application.

  • Oracle Linux operating system is required for Oracle Database Server and SAP NetWeaver Application Servers with Oracle client installed. For more information, see SAP Note 2358420 - Oracle Database Support for Amazon Web Services EC2 (SAP portal access required).

For each of these operating systems, you can bring your own subscription to AWS or use the Amazon Machine Images (AMIs) from the AWS Marketplace.
