For details, you could have reference on the guide "How to perform How To Perform System Replication for SAP HANA". mapping rule : internal_ip_address=hostname. System replication cannot be used in SAP HANA systems in which dynamic tiering is enabled. Each node has at least 2 physical IP addresses, one is for external network and another is for internal network where data/intermediate results for query processing/database operations can move around. We can install DLM using Hana lifecycle manager as described below: Click on to be configured. * In the first example, the [system_replication_communication]listeninterface parameter has been set to .global and only the hosts of the neighboring replicating site are specified. Or see our complete list of local country numbers. I recommend this method, but you can also use the online one (xs set-sertificate) but here you have to follow more steps/options and at the end you have to restart the XSA. Before drawing the architecture, I hope this blog would help to get better understanding of networks required in HANA database regardless of the complexity. Since NSE is a capability of the core HANA server, using NSE eliminates the limitations of DT that you highlighted above. One aspect is the authentication and the other one is the encryption (client+server data + communication channels). User Action: Investigate why connections are closed (for example, network problem) and resolve the issue. Switches system replication primary site to the calling site. savepoint (therefore only useful for test installations without backup and
For more information, see Configuring Instances. SAP Data Intelligence (prev. Data Hub) Connection. RFC Module. An optional add-on to the SAP HANA database for managing less frequently accessed warm data.
