These changes allowed to improve the cluster architecture and to The updated certification SAP S/4-HA-CLU 1.0 redefines some of the test proceduresĪnd describes new expectations how the cluster should behave in specialĬonditions. Support of more than two cluster nodes for ASCS and ERS instances allowed. SAP HACheckMaintenanceMode and HASetMaintenanceMode. Support of automated HA maintenance mode for SAP resources by implementing support of Standard SAP installation to improve support processes. Integration of the cluster with the SAP start framework sapstartsrv toĮnsure that maintenance procedures do not break the cluster stability. Years of productive operations, the components mentioned have proven their maturityįor customers of different sizes and industries. An optimal effect of the enqueue replication mechanism canīe achieved when combining the application level redundancy with a highĪvailability cluster solution, as provided for example by SUSE Linux Enterprise Server for SAP Applications. Level redundancy for one of the most crucial components of the SAP S/4HANA ABAP Platform stack, The SAP Enqueue Replication Server 2 constitutes application SAP S/4HANA ABAP Platform is a common stack of middleware functionality used to support SAPīusiness applications. The described cluster solution can be used for SAP* SAP S/4HANA ABAP Platform. Many critical business environments require the highest SAP* Business Suite is a sophisticated application platform for large enterprisesĪnd mid-size companies. Of the technical infrastructure, single points of failure can be eliminated.
