SAP HANA system replication is a mechanism for ensuring the high availability of your SAP HANA system. Through the continuous replication of data from a primary to a secondary system, including in-memory loading, system replication facilitates rapid failover in the event of a disaster. Productive operations can be resumed with minimal downtime.
It's important to understand that the persistence for the SAP HANA cockpit is an embedded SAP HANA express edition (HXE) database used to store all the cockpit's metadata. The cockpit also includes and utilizes the SAP HANA extended services, advanced model (XSA) application server. Both the HXE database and XSA are automatically installed and configured when you install the cockpit.
To make sure that the cockpit is highly available, you can set up system replication for SAP HANA cockpit (that is for the embedded HXE database and for XSA). The procedure to set up system replication for SAP HANA cockpit is described in this document.
