This course is designed to enable you to deploy the SAP Enqueue Replication Server with High Availability using SLES for SAP Applications. The course uses SUSE best practices leading to a deployment that complies with the SAP certification NW-HA-CLU 7.40 for ENSA1 and S/4-HA-CLU 1.0 for ENSA2. First the Enqueue Server is introduced along with an architectural overview. Next the environment required for the deployment is explored including the storage requirements for deploying the enqueue server with high availability. The preparation is followed by tuning the systems for the SAP workload, creating and configuring the required cluster resources and integrating the SAP environment with the HA environment using the sap_suse_cluster_connector. Cluster tests are then planned and executed, the cluster monitored and best practice administration tips provided.

This course helps prepare students for the SCE in SLES for SAP Applications - Part 1 exam. 

Attendees should have knowledge of SLES equivalent to the SCA in SUSE Linux Enterprise Sever level along with an in-depth understanding of the SUSE Linux Enterprise High Availability Extension or general High Availability concepts. This course does not require any specific SAP product knowledge.
