To learn more about this step, see These are all pretty broad topic and for now we will focus on the x.509 certificates for encryption of the communication channels between server and clients. The extended store can reduce the size of your in-memory database. Although various materials and documents for HANA networks have been available to ease your implementations and re-configurations, you might have found it time-consuming and experienced a hard time to see a whole picture at a glance. From Solution Manager 7.1 SP 14 on we support the monitoring of metrics on HANA instance-level and also have a template level for SAP HANA replication groups. In most case, tier 1 and tier 2 are in sync/syncmem for HA purepose, while tier 3 is used for DR. A security group acts as a virtual firewall that controls the traffic for one or more Therefore, I would highly recommend to stick with the default value .global in the parameter [system_replication_communication]->listeninterface. shipping between the primary and secondary system. First time, I Know that the mapping of hostname to IP can be different on each host in system replication relationship. Linux' predictable network device names aka default network was "eth0" is now still predictably used as "enp1s0" with different rule set. For more information, see: This will speed up your login instead of using the openssl variant which you discribed. replication. 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. # 2020/04/14 Insert of links / blogs as starting point, links for part II You can configure additional network interfaces and security groups to further isolate 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. Replication, Start Check of Replication Status
The bottom line is to make site3 always attached to site2 in any cases. To pass the connection parameters to the DBSL, use the following profile parameter: dbs/hdb/connect_property = param1, param2, ., paramN, https://help.sap.com/viewer/b3ee5778bc2e4a089d3299b82ec762a7/2.0.04/en-US/0ae2b75266df44499d8fed8035e024ad.html. Introduction. 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. Contact us. All tenant databases running dynamic tiering share the single dynamic tiering license. 2487639 HANA Basic How-To Series HANA and SSL MASTER KBA We are actually considering the following scenarios: mapping rule : system_replication_internal_ip_address=hostname, 1. 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. * Dedicated network for system replication: 10.5.1. When set, a diamond appears in the database column. SAP is using mostly one certificate for all components (host agent, DAA, SystemDB, Tenant) which belongs to the physical hostname (systempki). Recently we started receiving the alerts from our monitoring tool: Unregisters a system replication site on a primary system. Attach the network interfaces you created to your EC2 instance where SAP HANA is Internal communication channel configurations(Scale-out & System Replication), Part2. Extended tables behave like all other SAP HANA tables, but their data resides in the disk-based extended store. Perform SAP HANA
network interfaces you will be creating. Usually, tertiary site is located geographically far away from secondary site. 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 customizable_functionalities property is defined in the SYSTEMDB globlal.ini file at the system level. # 2020/4/15 Inserted Vitaliys blog link + XSA diagnose details If you want to force all connection to use SSL/TLS you have to set the sslenforce parameter to true (global.ini). This is necessary to start creating log backups. Tertiary Tier in Multitier System Replication, Operations for SAP HANA Systems and Instances, Enable / Disable Fullsync System

We have a Production HANA landscape on HANA 1.0 SPS12 with a 4+0 Scaleout setup with HANA System replication to TIER2 in the same Primary Datacenter and TIER3 in the Secondary Datacenter This has never occurred in the past as the System Replication monitor immediately reflects the TIER3 as soon as the Replication is configured, Further checks confirmed each volume from TIER2 was indeed replicating to TIER3 and it took the same amount of time it usually takes to synchronize, yet no signs of the TIER3 on HANA Studio Replication monitor Using HANA studio. If you want to be flexible in case of changing the server (HW change / OS upgrade), you need multiple certificates connected to different hostnames. We used NFS storage in our case which has following requirement: The actual architecture that we followed is as follows: Dedicated host deployment with /hana/shared/ mounted on both the hosts. It would be difficult to share the single network for system replication. Ensures that a log buffer is shipped to the secondary system
The BACKINT interface is available with SAP HANA dynamic tiering. Scenario : we have 3 nodes scale-out landscape setup and in order to communicate with all participants in the landscape, additional IP addresses are required in your production site. But still some more options e.g. Which communication channels can be secured? Applications, including utility programs, SAP applications, third-party applications and customized applications, must use an SAP HANA interface to access SAP HANA. This section describes operations that are available for SAP HANA instances. When you launch an instance, you associate one or more security groups with the number. # 2021/03/18 Inserted XSA high security Kudos out to Patrick Heynen as in a separate communication channel for storage. Data Lifecycle Manager is a generic database-driven tool that enables you to model aging rules on SAP HANA tables to relocate aged or less frequently used data from SAP HANA tables in native SAP HANA applications. Before we get started, let me define the term of network used in HANA. ########. Log mode
primary and secondary systems. Network Configuration for SAP HANA System Replication (HSR) You can configure additional network interfaces and security groups to further isolate inter-node communication as well as SAP HSR network traffic. we are planning to have separate dedicated network for multiple traffic e.g. # 2021/04/06 Inserted possibility for multiple SAN in one request / certificate with sapgenpse Figure 12: Further isolation with additional ENIs and security When complete, test that the virtual host names can be resolved from SAP HANA Native Storage Extension ("NSE") is the recommended approach to implementing data tiering within an SAP HANA system. ENI-3 The systempki should be used to secure the communication between internal components. Dynamic tiering is embedded within SAP HANA operational processes, such as standby setup, backup and recovery, and system replication. Step 1. -Jens (follow me on Twitter for more geeky news @JensGleichmann), ######## Surprisingly the TIER3 system replication status did not show up on the Replication monitor in HANA studio Most SAP documentations are for simple environments with one network interface and one IP label on it. Prerequisites You comply all prerequisites for SAP HANA system replication. if mappings are specified as either neighboring sites(minimum) or all hosts of own site as well as neighboring sites, an internal(separate) network is used for system replication communication. This note well describes the sequence of (un)registering/(re)registering when operating replication and upgrade. Disables system replication capabilities on source site. Introduction. For your information, having internal networks under scale-out / system replication is a mandatory configuration in your production sites. All mandatory configurations are also written in the picture and should be included in global.ini. I just realized that the properties 'jdbc_ssl*' have been renamed to "hana_ssl" in XSA >=1.0.82. You have assigned the roles and groups required. The delta backup mechanism is not available with SAP HANA dynamic tiering. operations or SAP HANA processes as required. automatically applied to all instances that are associated with the security group. To learn For more information about network interfaces, see the AWS documentation. An elastic network interface is a virtual network interface that you can attach to an Be careful with setting these parameters! (check SAP note 2834711). Scale-out and System Replication(3 tiers). So site1 & site3 won't meet except the case that I described. properties files (*.ini files). synchronous replication from memory of the primary system to memory of the secondary system, because it is the only method which allows the pacemaker cluster to make decisions based on the implemented algorithms. Each tenant requires a dedicated dynamic tiering host. Here your should consider a standard automatism. By default, this enables security and forces all resources to use ssl. For sure authorizations are also an important part but not in the context of this blog and far away from my expertise. Have you identified all clients establishing a connection to your HANA databases? In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. Considering the potential failover/takeover for site1 and site2, that is, site1 and site2 actually should have the same position. Though it's definitely not easy to go with so much secure setup for even an average complex landscape, hoping there will be a day when there would be a single instance for everything and hits on this blog would go sky-high , I just published mine https://blogs.sap.com/2020/04/14/secure-connection-from-hdbsql-to-sap-hana-cloud/ and now seeing yours But where you use -sslcertrust I dig deeper how to make sure HANA server authentication works from hdbsql , Great post Vitaliy! Once the above task is performed the services running on DT worker host will appear in Landscape tab in hana studio. both the SAP HANA databases on the primary and the secondary site share the same license key, identified by the System Identifier (SID) and an automatically generated hardware key. System replication overview Replication modes Operation modes Replication Settings Both SAP HANA and dynamic tiering hosts have their own dedicated storage. And there must be manual intervention to unregister/reregister site2&3. You can use SAP Landscape Management for
