Here you can reuse your current automatism for updating them. From HANA Scale-out documentation(SAP HANA Administration Guide -> [Availability and Scalability] -> [Scaling SAP HANA] -> [Configuring the Network for Multiple Hosts]), there are 2 configurable parameters. On every installation of an SAP application you have to take care of this names. The customizable_functionalities property is defined in the SYSTEMDB globlal.ini file at the system level. Considering the potential failover/takeover for site1 and site2, that is, site1 and site2 actually should have the same position. 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. A shared file system (for example, /HANA/shared) is required for installation. replication network for SAP HSR. In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. Internal Network Configurations in System Replication : There are also configurations you can consider changing for system replications. Tertiary Tier in Multitier System Replication, Operations for SAP HANA Systems and Instances, Enable / Disable Fullsync System Since NSE is a capability of the core HANA server, using NSE eliminates the limitations of DT that you highlighted above. The last step is the activation of the System Monitoring. different logical networks by specifying multiple private IP addresses for your instances. global.ini: Set inside the section [communication] ssl from off to systempki. 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. This is mentioned as a little note in SAP note 2300943 section 4. network interface, see the AWS If set on , Problem. The cleanest way is the Golden middle option 2. Maintain, reccomend and install SAP software for our client, including SAP Netweaver, ECC,R/3, APO and BW. database, ensure the following: To allow uninterrupted client communication with the SAP HANA Surprisingly the TIER3 system replication status did not show up on the Replication monitor in HANA studio shipping between the primary and secondary system. minimizing contention between Amazon EBS I/O and other traffic from your instance. Otherwise, please ignore this section. overwrite means log segments are freed by the HANA documentation. For more information, see: the OS to properly recognize and name the Ethernet devices associated with the new systems, because this port range is used for system replication The required ports must be available. Separating network zones for SAP HANA is considered an AWS and SAP best practice. instance. The host and port information are that of the SAP HANA dynamic tiering host. Primary Host: Enable system replication. the global.ini file is set to normal for both systems. For more information, see Configuring Instances. All mandatory configurations are also written in the picture and should be included in global.ini. Once the above task is performed the services running on DT worker host will appear in Landscape tab in hana studio. As you may read between the lines Im not a fan of authorization concepts. (1) site1 is broken and needs repair; 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. mapping rule : internal_ip_address=hostname. Network and Communication Security. Figure 12: Further isolation with additional ENIs and security If you raise the isolation level to high after the fact, the dynamic tiering service stops working. 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. Step 1 . instances. The delta backup mechanism is not available with SAP HANA dynamic tiering. 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. Configure SAP HANA hostname resolution to let SAP HANA communicate over the 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. SAP HANA dynamic tiering is an integrated component of the SAP HANA database and cannot be operated independently from SAP HANA. The values are visible in the global.ini file of the tenant database but cannot be modified from the tenant database. that the new network interfaces are created in the subnet where your SAP HANA instance In my opinion, the described configuration is only needed below situations. 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. instance, see the AWS documentation. Your application automatically determines which tier to save data to: the SAP HANA in-memory store (the hot store), or extended storage (the warm store). Step 2. Here most of the documentation are missing details and are useless for complex environments and their high security standards with stateful connection firewalls. Global Network We continue to fully maintain the SP05 version and deliver PL releases as necessary but there are no plans to release newer SP versions for DT. You provision (or add) the dynamic tiering service (esserver) on the dedicated host to the tenant. You set up system replication between identical SAP HANA systems. If you set jdbc_ssl to true will lead to encrypt all jdbc communications (e.g. A service in this context means if you have multiple services like multiple tenants on one server running. Perform SAP HANA SAP HANA Native Storage Extension ("NSE") is the recommended approach to implementing data tiering within an SAP HANA system. To use the Amazon Web Services Documentation, Javascript must be enabled. * en -- ethernet The OS process for the dynamic tiering host is hdbesserver, and the service name is esserver. # 2021/03/18 Inserted XSA high security Kudos out to Patrick Heynen And there must be manual intervention to unregister/reregister site2&3. This will speed up your login instead of using the openssl variant which you discribed. Actually, in a system replication configuration, the whole system, i.e. We are not talking about self-signed certificates. Public communication channel configurations, 2. global.ini -> [communication] -> listeninterface : .global or .internal # Inserted new parameters from 2300943 Dynamic tiering is targeted at SAP HANA database sizes of 512 GB and larger, where large data volumes begin to necessitate a data lifecycle management solution. SAP HANA Network Settings for System Replication 9. Dynamic tiering is embedded within SAP HANA operational processes, such as standby setup, backup and recovery, and system replication. resolution is working by creating entries in all applicable host files or in the Domain labels) and the suitable routing for a stateful connection for your firewall rules and network segmentation. 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 To change the TLS version and the ciphers for the XSA you have to edit the xscontroller.ini. Log mode normal means that log segments are backed up. SAP HANA 1.0, platform edition Keywords. More and more customers are attaching importance to the topic security. Now you have to go to the HANA Cockpit Manager to change the registered resource to use SSL. Be careful with setting these parameters! We are talk about signed certificates from a trusted root-CA. Operators Detail, SAP Data Intelligence.
