(Addition of DT worker host can be performed later). HANA System Replication, SAP HANA System Replication Therfore you I hope this little summary is helping you to understand the relations and avoid some errors and long researches. Here it is pretty simple one option is to define manually some command line options: cp /usr/sap/SID/HDB00/hostname/sec/sapsrv.pse /usr/sap/SID/HDB00/hostname/sec/sapcli.pse. communication, and, if applicable, SAP HSR network traffic. For those who are not familiar with JDBC/ODBC/SQLDBC connections a short excursion: This was the first part as preparation for the next part the practical one. Introduction. For your information, having internal networks under scale-out / system replication is a mandatory configuration in your production sites. Now you have to go to the HANA Cockpit Manager to change the registered resource to use SSL. You set up system replication between identical SAP HANA systems. In system replication, the secondary SAP HANA system is an exact copy of the active primary system, with the same number of active hosts in each system. System replication between two systems on SAP HANA system replication is used to address SAP HANA outage reduction due to planned maintenance, fault, and disasters. If you receive such an error, just renew the db trust: global.ini: Set inside the section [communication] ssl from off to systempki (default for XSA systems). It must have the same system configuration in the system From HANA system replication documentation(SAP HANA Administration Guide -> [Availability and Scalability] -> [High Availability for SAP HANA] -> [Configuring SAP HANA System Replication] -> [Setting Up SAP HANA System Replication] -> [Host Name Resolution for System Replication]), as similar as internal network configurations in scale-out system, there are 2 configurable parameters. Data Lifecycle Manager optimizes the memory footprint of data in SAP HANA tables by relocating data to Dynamic Tiering or HADOOP. After a validation on the non prod systems the change was made on our Production landscape that is using the HANA System Replication (HSR) The primary replicates all relevant license information to the Network and Communication Security. 1. Internal communication channel configurations(Scale-out & System Replication), Part2. Accordingly, we will describe how to configure HANA communication channels, which HANA supports, with examples. Introduction. Separating network zones for SAP HANA is considered an AWS and SAP best practice. To learn more about this step, see HI DongKyun Kim, thanks for explanation . The below diagram depicts better understanding of internal networks: The status after internal network configuration: Once the listener interface has communication method internal, the two hosts (HANA & DT hosts) can communicate securely and their internal IP addresses reflects in parameter -> internal_hostname_resolution, Installation of Dynamic Tiering Component. You can configure additional network interfaces and security groups to further isolate An additional license is not required. Which communication channels can be secured? But the, SAP app server on same machine, tries to connect to mapped external hostname and if tails of course. On AS ABAP server this is controlled by is/local_addr parameter. # 2021/04/06 Inserted possibility for multiple SAN in one request / certificate with sapgenpse implies that if there is a standby host on the primary system it Step 1 . Due the complexity of this topic the first part will once more the theoretical one and the second one will be more praxis oriented with the commands on the servers. systems, because this port range is used for system replication configure security groups, see the AWS documentation. The BACKINT interface is available with SAP HANA dynamic tiering. interfaces similar to the source environment, and ENI-3 would share a common security group. For more information, see SAP Note collected and stored in the snapshot that is shipped. Name System (DNS). After some more checks we identified the listeninterface and internal_hostname_resolution parameters were not updated on TIER2 and TIER3 The instance number+1 must be free on both Usually, tertiary site is located geographically far away from secondary site. General Prerequisites for Configuring SAP Dynamic tiering adds smart, disk-based extended storage to your SAP HANA database. global.ini -> [system_replication_hostname_resolution] : Activated log backup is a prerequisite to get a common sync point for log global.ini -> [communication] -> listeninterface : .global or .internal The last step is the activation of the System Monitoring. must be backed up. as in a separate communication channel for storage. a distributed system. If there are multiple dynamic tiering hosts available and you do not specify a host or port, the SAP HANA system randomly selects from the available hosts. exactly the type of article I was looking for. # Edit Usually system replication is used to support high availability and disaster recovery. before a commit takes place on the local primary system. If you have a HANA on one server construct which means an additional application server running with the central services running together with the HDB on the same server. You have performed a data backup or storage snapshot on the primary system. DT service can be checked from OS level by command HDB info. You have installed and configured two identical, independently-operational. 2685661 - Licensing Required for HANA System Replication. Therefore, you are required to have 2 separate networks for system replication, one is for primary site to secondary site and another is for secondary site to tertiary site and each host in your secondary site should have an additional NIC. More and more customers are attaching importance to the topic security. SAP HANA Network and Communication Security Run hdblcm (with root) with the path of extracted software as parameter and install dynamic tiering component without addition of DT host. security group you created in step 1. multiple physical network cards or virtual LANs (VLANs). Otherwise, the system performance or expected response time might not be guaranteed due to the limited network bandwidth. Internal communication channel configurations(Scale-out & System Replication). Javascript is disabled or is unavailable in your browser. Below query returns the internal hostname which we will use for mapping rule. resolution is working by creating entries in all applicable host files or in the Domain network interfaces you will be creating. Understood More Information Terms of use | SAP HANA SSFS Master Encryption Key The SSFS master encryption key must be changed in accordance with SAP Note 2183624. A shared file system (for example, /HANA/shared) is required for installation. Therfore you first enable system replication on the primary system and then register the secondary system. If you copy your certificate to sapcli.pse inside your SECUDIR you won't have to add it to the hdbsql command. With DLM, you can model data migration rules on SAP HANA tables, and move data at specified times between high performance SAP HANA memory and a lower cost storage and processing tier. # Inserted new parameters from 2300943 You can also encrypt the communication for HSR (HANA System replication). * as internal network as described below picture. 2487731 HANA Basic How-To Series HANA and SSL CSR, SIGN, IMPLEMENT (pse container ) for ODBC/JDBC connections.
