Step 6. Perform Post-Deployment Tasks - SAP HANA on AWS

Step 6. Perform Post-Deployment Tasks

Before you start using your SAP HANA instance, we recommend that you perform the following post-deployment steps. For details, refer to the SAP HANA Installation and Update Guide on the SAP website.

  • Make sure that you are running on the latest supported kernel. For details, see SAP OSS Notes 2205917 or 2240716 for SLES, and and 2246163 or 2292690 for RHEL.

  • If you are using RHEL for SAP or SLES for SAP as your operating system, C-states and P-states are automatically set by using saptune (for SLES) and tuned-adm (for RHEL) on all supported EC2 instances. You need to reboot your instance after deployment to enable this. If you are using SLES as your operating system, configure C-states and P-states for lower latency by following the instructions provided in the SAP OSS Note 2205917 for SLES 12 or above.

  • Update your SAP HANA software with the latest patches.

  • Install any additional components such as Application Function Libraries (AFL) or Smart Data Access (SDA).

  • If you have deployed an SAP HANA scale-out cluster, consider adding additional elastic network interfaces (ENIs) and security groups to logically separate network traffic for client, inter-node, and optional SAP HANA System Replication (HSR) communications. For details, see the SAP HANA Operations Guide.

  • Configure and back up your newly installed SAP HANA database.

  • Consider creating a scheduled snapshot for your backup volume. For instructions, see Take Scheduled EBS Snapshots in the Amazon CloudWatch documentation.

  • For Multi-AZ, high-availability deployments, we strongly recommend that you validate the setup of your environment before you use the HA cluster for production. After the successful completion of the Quick Start and before you deploy an application on SAP HANA, run a round of tests to ensure that failover and failback are working as desired. For testing scenarios, see section 6 of the SUSE whitepaper, SAP HANA SR Performance Optimized Scenario.
