HI DongKyun Kim, thanks for explanation . enables you to isolate the traffic required for each communication channel. Starts checking the replication status share. Keep the tenant isolation level low on any tenant running dynamic tiering. You need a minimum SP level of 7.2 SP09 to use this feature. 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. With MDC (or like SAP says now container/tenants) you always have a systemDB and a tenant. This note well describes the sequence of (un)registering/(re)registering when operating replication and upgrade. Global Network /hana/shared should be mounted on both the hosts namely HANA host and Dynamic Tiering host which will contain installation files of HANA and Dynamic Tiering service. This blog provides an overview of considerations and recommended configurations in order to manage internal communication channels among scale-out / system replications. Ensure that host name-to-IP-address overwrite means log segments are freed by the # 2021/09/09 updated parameter info: is/local_addr thx @ Matthias Sander for the hint It is also important to configure the appropriate network communication routing, because per default every traffic on a Linux server goes per default over the default gateway which is by default the first interface eth0 (we will need this know how later for the certificates). Changed the parameter so that I could connect to HANA using HANA Studio. Below query returns the internal hostname which we will use for mapping rule. 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. ###########. In my opinion, the described configuration is only needed below situations. (Storage API is required only for auto failover mechanism). no internal interface found, listeninterface, .internal , KBA , HAN-DB , SAP HANA Database , Problem . SAP HANA dynamic tiering adds the SAP HANA dynamic tiering service (esserver) to your SAP HANA system.

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. Stopped the Replication to TIER2 and TIER3 and removed them from the system replication configuration 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 the OS to properly recognize and name the Ethernet devices associated with the new 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. This option requires an internal network address entry. General Prerequisites for Configuring SAP These are called EBS-optimized Internal Network Configurations in System Replication : There are also configurations you can consider changing for system replications. Name System (DNS). Alerting is not available for unauthorized users, Right click and copy the link to share this comment. 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. mapping rule : internal_ip_address=hostname. own security group (not shown) to secure client traffic from inter-node communication. Secondary : Register secondary system. (3) site3 is still registered to the site2 (as it's not impacted, async only as remote DR); System replication cannot be used in SAP HANA systems in which dynamic tiering is enabled. Thanks for letting us know this page needs work. first enable system replication on the primary system and then register the secondary A shared file system (for example, /HANA/shared) is required for installation. if no mappings specified(Default), the default network route is used for system replication communication. It must have the same number of nodes and worker hosts. One aspect is the authentication and the other one is the encryption (client+server data + communication channels).

The host and port information are that of the SAP HANA dynamic tiering host. primary and secondary systems. # Edit Please use part one for the knowledge basics. exactly the type of article I was looking for. HANA System Replication, SAP HANA System Replication You set up system replication between identical SAP HANA systems. Binds the processes to this address only and to all local host interfaces. SAP HANA System, Secondary Tier in Multitier System Replication, or More recently, we implemented a full-blown HANA in-memory platform . Extracting the table STXL. Run hdblcm (with root) with the path of extracted software as parameter and install dynamic tiering component without addition of DT host. 2211663 . * In the first example, the [system_replication_communication]listeninterface parameter has been set to .global and the neighboring hosts are specified. 1. 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. Setting up SAP data connection. When you launch an instance, you associate one or more security groups with the It is also possible to create one certificate per tenant. Pre-requisites. a distributed system. minimizing contention between Amazon EBS I/O and other traffic from your instance. SAP HANA communicate over the internal network. In the following example, two network interfaces are attached to each SAP HANA node as well Both SAP HANA and dynamic tiering hosts have their own dedicated storage. A full sync was triggered to TIER2 and after the completion the TIER3 full sync was triggered SAP HANA Native Storage Extension ("NSE") is the recommended approach to implementing data tiering within an SAP HANA system. Therefore, I would highly recommend to stick with the default value .global in the parameter [system_replication_communication]->listeninterface. Storage snapshots cannot be prepared in SAP HANA systems in which dynamic tiering is enabled. 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. 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. Stay healthy, For more information about how to create and 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). Before drawing the architecture, I hope this blog would help to get better understanding of networks required in HANA database regardless of the complexity. Please provide your valuable feedback and please connect with me for any questions. Above configurations are only required when you have internal networks. Here you can reuse your current automatism for updating them. 2487639 HANA Basic How-To Series HANA and SSL MASTER KBA Which communication channels can be secured? Unregisters a secondary tier from system replication. Setting Up System Replication You set up system replication between identical SAP HANA systems. documentation. For instance, third party tools like the backup tool via backint are affected. path for the system replication. 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. Therfore you Please keep in mind to configure the correct default gateway with is/local_addr for stateful firewall connections. can use elastic network interfaces combined with security groups to achieve this network * Dedicated network for system replication: 10.5.1. 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. There are some documentations available by SAP, but some of them are outdated or not matching the customer environments/needs or not all-embracing. * ww -- wwan, Ethernet cards will always start withen, but they might be followed by a, its key to remember the hex conversion of network cards, https://major.io/2015/08/21/understanding-systemds-predictable-network-device-names/. database, ensure the following: To allow uninterrupted client communication with the SAP HANA Deploy SAP Data Warehouse Foundation (Data Lifecycle Manager) Delivery Unit on SAP HANA.
