Using SLES for SAP Applications 15 to Provide High Availability for S/4HANA and Netweaver
This course is designed to enable you to deploy SAP Enqueue Replication Server with High Availability using SLES for SAP applications. The course uses SUSE best practices to achieve a deployment compliant with SAP NW-HA-CLU 7.40 for ENSA1 and S/4-HA-CLU 1.0 for ENSA2. First, the Enqueue server is presented with an overview of the architecture. Next, the environment needed for the implementation is analyzed, including the storage requirements for the high-availability Enqueue server implementation. Preparation is followed by setting up the systems for the SAP workload, creating and configuring the necessary cluster resources, and integrating the SAP environment with the HA environment using the sap_suse_cluster_connector. Cluster testing is then planned and executed, the cluster is monitored, and suggestions on best administration practices are provided.
The course helps students prepare for the SCE exam in SLES for SAP Applications-Part 1.
COD: SLE322v15
CATEGORY:Â Linux Enterprise Server
Who should participate
Administrators in charge of managing systems running S/4HANA or SAP applications hosted on the NetWeaver ABAP platform who need a high-availability solution for the Enqueue server hosted on a SLES for SAP Applications HA cluster. The configuration of a cluster hosting ENSA1 will conform to SAP NW-HA-CLU 7.40 certification, while that of a cluster hosting ENSA2 will conform to SAP S/4-HA-CLU 1.0 certification.
Prerequisites
Participants should have SLES knowledge equivalent to the SUSE Linux Enterprise Sever SCA level and a thorough understanding of the SUSE Linux Enterprise High Availability Extension or general High Availability concepts. This course does not require any specific knowledge of SAP products.
