SLD Registration for SAP HANA SR Systems
This page describes the SLD registration for SAP HANA systems installed with system replication for high-availability. This option is available for SAP HANA installations with or without multi-tenancy database containers (MDC). If your SAP HANA database is installed with MDC, please note that the changes described below apply to the SYSTEM-DB as well as to each tenant.
Register SAP HANA SR system in SLD
One of the most important changes that enable us to model SAP HANA SR systems in SLD and LMDB is the implementation of a new association that enables us to model relationships between DB replication groups. This also lead to the introduction of a new parameter in the profile on the SAP HANA system. If all works correctly in the end the associations in the SLD should look like this:
In the graphic above you can see that each SLD DS creates an own CIM Object of Type SAP_Database_System.
The SAP_Database_System created by the SLD DS of the Application Server (1) is named “Virtual Database”, the SAP_Database_System(s) created by the HANA SLD DS (2) are named “Physical Database”. The relationship between the “Virtual Database” and the “Physical Database” which is the Primary DB is modeled with the Association SAP_IdenticalDatabaseSystem (3). The relationship between the Primary DB and the Secondary DB is modeled with the Associations SAP_DatabaseReplicationDependency (4).
To be able to report the system replication dependencies SAP_DatabaseReplicationDependency within SAP HANA you need at least SAP HANA 1.0 revision 102.02 or higher. To be able to report SAP_IdenticalDatabaseSystem automatically via the parameter SLDVIRTDBHOME you need at least SAP HANA 1.0 revision 110 or higher.
