Using command line tool hdbnsutil: Primary : alter system alter configuration ('xscontroller.ini','SYSTEM') set ('communication','jdbc_ssl') = 'true' with reconfigure; You can use the same procedure for every other XSA installation. In this case, you are required to add additional NIC, ip address and cabling for site1-3 replication. (more details in 8.) replication network for SAP HSR. well as for SAP HSR, Storage zone to persist SAP HANA data in the storage infrastructure for If set on the primary system, the loaded table information is Storage snapshots cannot be prepared in SAP HANA systems in which dynamic tiering is enabled. as in a separate communication channel for storage. With an elastic network interface (referred to as global.ini -> [internal_hostname_resolution] : primary and secondary systems. For more information about how to create a new The new rules are When complete, test that the virtual host names can be resolved from It must have the same SAP system ID (SID) and instance To learn more about this step, see Configuring Hostname Resolution for SAP HANA System Replication in the SAP ########. Persistence encryption of the SAP HANA system is not available when dynamic tiering is installed. After the dynamic tiering component has been installed on HANA system, start with addition of worker DT host, by running hdblcm from worker DT node. I have not come across much documentation on this topic and not sure if any customer experienced such a behavior so put up a post to describe the scenario SAP HANA and dynamic tiering each support NFS and SAN storage using storage connector APIs.

IMPORTANT : the parameters in the global.ini must be set prior to registering the secondary system which means that you need to un-register and re-register if you want to change the configurations. SAP HANA supports asynchronous and synchronous replication modes. Keep the tenant isolation level low on any tenant running dynamic tiering. shipping between the primary and secondary system. So I think each host, we need maintain two entries for "2. Linux' predictable network device names aka default network was "eth0" is now still predictably used as "enp1s0" with different rule set. In multiple-container systems, the system database and all tenant databases # Edit # 2021/03/18 Inserted XSA high security Kudos out to Patrick Heynen Early Watch Alert shows a red alert at section "SAP HANA Network Settings for System Replication Communication (listeninterface)": enable_ssl, system_replication_communication, global.ini, .global, TLS, encrypted communication expected, when, off, listeninterface , KBA , HAN-DB-SEC , SAP HANA Security & User Management , HAN-DB , SAP HANA Database , SV-SMG-SER-EWA , EarlyWatch Alert , HAN-DB-HA , SAP HANA High Availability (System Replication, DR, etc.) Stop secondary DB.

ISSUE: We followed the SAP note 2183363, and updated the listeninterface and internal_hostname_resolution HANA parameters on our non prod systems in a similar scaleout setup. These steps helped resolve the issue and the System Replication monitor was now reflecting all 3 TIERS Because site1 and site2 usually resides in the same data center but site3 is located very far in another data center. For the section [system_replication_hostname_resolution], you can add either all hosts or neighboring sites, but I am going to add only neighboring sites in order to remove all the configuration conflicts in below examples. Deploy SAP Data Warehouse Foundation (Data Lifecycle Manager) Delivery Unit on SAP HANA. For your information, having internal networks under scale-out / system replication is a mandatory configuration in your production sites. Have you already secured all communication in your HANA environment? Be careful with setting these parameters! Since quite a while SAP recommends using virtual hostnames. In general, there is no needs to add site3 information in site1, vice versa. secondary. Therefore, I would highly recommend to stick with the default value .global in the parameter [system_replication_communication]->listeninterface. Network and Communication Security. The same instance number is used for Follow the system. Alerting is not available for unauthorized users, Right click and copy the link to share this comment, can consider changing for internal network, Public communication channel configurations, Internal communication channel configurations(Scale-out & System Replication), external(public) network : Channels used for external access to SAP HANA functionality by end-user clients, administration clients, application servers, and for data provisioning via SQL or HTTP, internal network : Channels used for SAP HANA internal communication within the database or, in a distributed scenario, for communication between hosts, This option does not require an internal network address entry.(Default). documentation. After a validation on the non prod systems the change was made on our Production landscape that is using the HANA System Replication (HSR) Create virtual host names and map them to the IP addresses associated with client, communication, and, if applicable, SAP HSR network traffic. I haven't seen it yet, but I will link it in this post.The hdbsql connect in this blog was just a side effect which I have tested due to script automatism when forcing ssl . Would be good to have any feedback from any customers that have come across this and it will be useful for any customers that are planning to make this change in their landscape, Alerting is not available for unauthorized users.
