sap hana network settings for system replication communication listeninterface

Operators Detail, SAP Data Intelligence. Once again from part I which PSE is used for which service: SECUDIR=/usr/sap//HDBxx//sec. Questo articolo descrive come distribuire un sistema SAP HANA a disponibilit elevata in una configurazione con scalabilit orizzontale. Name System (DNS). Refresh the page and To Be Configured would change to Properly Configured. Therfore you first enable system replication on the primary system and then register the secondary system. You can modify the rules for a security group at any time. Dynamic tiering enhances SAP HANA with large volume, warm data management capability. You can also create an own certificate based on the server name of the application (Tier 3). United States. For more information, see: An additional license is not required. 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 The values are visible in the global.ini file of the tenant database but cannot be modified from the tenant database. The same instance number is used for configure security groups, see the AWS documentation. global.ini -> [communication] -> listeninterface : .global or .internal Secondary : Register secondary system. SAP is using mostly one certificate for all components (host agent, DAA, SystemDB, Tenant) which belongs to the physical hostname (systempki). SAP HANA supports asynchronous and synchronous replication modes. 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. Are you already prepared with multiple interfaces (incl. If you want to force all connection to use SSL/TLS you have to set the sslenforce parameter to true (global.ini). redirection. Starting point: mapping rule : system_replication_internal_ip_address=hostname, As you recognized, .internal setting is a subset of .global and .global is a default and .global supports both 2-tiers and 3-tiers. reason: (connection refused). An elastic network interface is a virtual network interface that you can attach to an SAP HANA dynamic tiering is an integrated component of the SAP HANA database and cannot be operated independently from SAP HANA. You can also encrypt the communication for HSR (HANA System replication). To detect, manage, and monitor SAP HANA as a mapping rule : internal_ip_address=hostname. communication, and, if applicable, SAP HSR network traffic. You can also select directly the system view PSE_CERTIFICATES. Therfore you number. 2487731 HANA Basic How-To Series HANA and SSL CSR, SIGN, IMPLEMENT (pse container ) for ODBC/JDBC connections. System replication between two systems on # 2020/04/14 Insert of links / blogs as starting point, links for part II To change the TLS version and the ciphers for the XSA you have to edit the xscontroller.ini. Thanks for letting us know we're doing a good job! On existing HANA DB host we already have two file systems for DATA and LOG: On Dynamic Tiering Host the following file systems are required which will store ES data and logs: So after the above setup the actual architecture will appear as follows: Communication channel and network requirements. Ensures that a log buffer is shipped to the secondary system 2475246 How to configure HANA DB connections using SSL from ABAP instance. If you want to be flexible in case of changing the server (HW change / OS upgrade), you need multiple certificates connected to different hostnames. This is mentioned as a little note in SAP note 2300943 section 4. With MDC (or like SAP says now container/tenants) you always have a systemDB and a tenant. How you can secure your system with less effort? For your information, I copy sap note SAP Note 1876398 - Network configuration for System Replication in SAP HANA SP6. to use SSL [, Configure HDB parameters for high security [, Pros and Cons certification collections [, HANA Cockpit (HTTPS)=> sapcontrol (SAP Start Service / sapstartsrv), HANA Cockpit (JDBC) => Database Explorer / Monitoring => Resources, Native Client Connection (ODBC/JDBC) => HANA. Set Up System Replication with HANA Studio. Import certificate to HANA Cockpit (for client communication) [, Configure clients (AS ABAP, ODBC, etc.) After some more checks we identified the listeninterface and internal_hostname_resolution parameters were not updated on TIER2 and TIER3 Be careful with setting these parameters! , Problem. We can install DLM using Hana lifecycle manager as described below: Click on to be configured. +1-800-872-1727. Persistence encryption of the SAP HANA system is not available when dynamic tiering is installed. 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. Which communication channels can be secured? Unless you are using SAPGENPSE, do not password protect the keystore file that contains the servers private key. Connection to On-Premise SAP ECC and S/4HANA. This is necessary to start creating log backups. Configuring SAP HANA Inter-Service Communication in the SAP HANA Extracting the table STXL. But keep in mind that jdbc_ssl parameter has no effect for Node.js applications! global.ini -> [system_replication_hostname_resolution] : For details how this is working, read this blog. 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. In this example, the target SAP HANA cluster would be configured with additional network One question though - May i know how are you Monitoring this SSL Certificates, which are applied on HANA DB ? If you've got a moment, please tell us what we did right so we can do more of it. (2) site2 take over the primary role; , Problem About this page This is a preview of a SAP Knowledge Base Article. SAP HANA System, Secondary Tier in Multitier System Replication, or Application Server, SAP HANA Extended Application Services (XS), and SAP HANA Studio, Internal zone to communicate with hosts in a distributed SAP HANA system as The parameter listeninterface=.global in the section [system_replication_communication] is used for system replication. You cant provision the same service to multiple tenants.

This is normally the public network. User Action: Investigate why connections are closed (for example, network problem) and resolve the issue. 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. For each server you can add an own IP label to be flexible. Removes system replication configuration. Every label should have its own IP. well as for SAP HSR, Storage zone to persist SAP HANA data in the storage infrastructure for * sl -- serial line IP (slip) Starts checking the replication status share. With SAP HANA SPS 10, during installation the system sets up a PKI infrastructure used to secure the internal communication interfaces and protect the traffic between the different processes and SAP HANA hosts. connection recovery after disaster recovery with network-based IP Above configurations are only required when you have internal networks. Share, Unregister Secondary Tier from System Replication, Unregister System Replication Site on This is the preferred method to secure the system as it's done automatically and the certificates are renewed when necessary. Copy the commands and deploy in SQL command. For more information about network interfaces, see the AWS documentation. Activated log backup is a prerequisite to get a common sync point for log Please use part one for the knowledge basics. 2300943 Enabling SSL encryption for database connections for SAP HANA extended application services, advanced model, 2487639 HANA Basic How-To Series HANA and SSL MASTER KBA. On AS ABAP server this is controlled by is/local_addr parameter. Configure SAP HANA hostname resolution to let SAP HANA communicate over the Stop secondary DB. An overview over the processes itself can be achieved through this blog. network interfaces you will be creating. steps described in the appendix to configure the IP labels and no client communication has to be adjusted. recovery. It must have the same software version or higher. There are two types of network used in HANA environment: Since we have a distributed scenario here, configuration of internal network becomes mandatory for better system performance and security. Storage snapshots cannot be prepared in SAP HANA systems in which dynamic tiering is enabled. Pre-requisites. The bottom line is to make site3 always attached to site2 in any cases. If you plan to use storage connector APIs, you must configure the multipath.conf and global.ini files before installation. enables you to isolate the traffic required for each communication channel. The delta backup mechanism is not available with SAP HANA dynamic tiering. 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. SAP Note 1834153 . Attach the network interfaces you created to your EC2 instance where SAP HANA is multiple physical network cards or virtual LANs (VLANs). of the same security group that controls inbound and outbound network traffic for the client So for s1host1,10.5.2.1=s2host110.4.3.1=s3host1, For s2host110.5.1.1=s1host110.4.3.1=s3host1, For s3host110.4.1.1=s1host110.4.2.1=s2host1. In a traditional, bare-metal setup, these different network zones are set up by having But the, SAP app server on same machine, tries to connect to mapped external hostname and if tails of course. +1-800-872-1727. documentation. Figure 12: Further isolation with additional ENIs and security License is generated on the basis of Main memory in Dynamic Tiering by choosing License type as mentioned below. I hope this little summary is helping you to understand the relations and avoid some errors and long researches. 2386973 - Near Zero DowntimeUpgradesforHANADatabase 3-tierSystemReplication. instances. Below query returns the internal hostname which we will use for mapping rule. For more information about how to create and The BACKINT interface is available with SAP HANA dynamic tiering. 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. So I think each host, we need maintain two entries for "2. SELECT HOST as hostname FROM M_HOST_INFORMATION WHERE KEY = net_hostnames; Internal Network Configurations in Scale-out : There are configurations youcan consider changing for internal networks. For instance, you have 10.0.1. A separate network is used for system replication communication. Solution Secure Network Settings for Internal SAP HANA Services To avoid opening an attack vector in an SAP HANA system, it is necessary to configure the settings for internal service communication in the recommended way. Figure 10: Network interfaces attached to SAP HANA nodes. The last step is the activation of the System Monitoring. the OS to properly recognize and name the Ethernet devices associated with the new The backup directories for both SAP HANA and dynamic tiering reside on a shared file system, allowing SAP HANA access to the dynamic tiering backup files. Check also the saphostctrl functionality for the monitoring: 2621457 hdbconnectivity failure after upgrade to 2.0, 2629520 Error : hdbconnectivity (HDB Connectivity), Status: Error (SQLconnect not possible (no hdbuserstore entry found)) While SAP Host Agent is not working correctly Solution Manager 7.2, Managed systems maintenance guide preparing databases. 1. After TIER2 full sync completed, triggered the TIER3 full sync You provision (or add) the dynamic tiering service (esserver) on the dedicated host to the tenant. Enables a site to serve as a system replication source site. The latest release version of DT is SAP HANA 2.0 SP05. overwrite means log segments are freed by the 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. It is also possible to create one certificate per tenant. 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. need not be available on the secondary system. It must have the same SAP system ID (SID) and instance instance. Changed the parameter so that I could connect to HANA using HANA Studio. 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. As you create each new network interface, associate it with the appropriate HANA documentation. mapping rule : system_replication_internal_ip_address=hostname, 1. DT service can be checked from OS level by command HDB info. Have you already secured all communication in your HANA environment? Changes the replication mode of a secondary site. When you launch an instance, you associate one or more security groups with the Using command line tool hdbnsutil: Primary : If you change the HANA hostname resolution, you will map the physical hostname which represents your default gateway to the original installed vhostname. Here your should consider a standard automatism. SAP HANA communicate over the internal network. system. Another thing is the maintainability of the certificates. 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. Instance-specific metrics are basically metrics that can be specified "by . tables are actually preloaded there according to the information Updated the listeninterface and internal_hostname_resolution parameters for the respective TIER as they are unique for every landscape Step 2. The primary replicates all relevant license information to the If you answer one of the questions negative you should wait for the second part of this series , ########### replication. Understood More Information 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. Here you can reuse your current automatism for updating them. 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. SAP User Role CELONIS_EXTRACTION in Detail. The XSA can be offline, but will be restarted (thanks for the hint Dennis). no internal interface found, listeninterface, .internal , KBA , HAN-DB , SAP HANA Database , Problem . This note well describes the sequence of (un)registering/(re)registering when operating replication and upgrade. Usually system replication is used to support high availability and disaster recovery. Have you identified all clients establishing a connection to your HANA databases? 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. 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. 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.) To set it up is one task, to maintain and operate it another. You need at You can configure additional network interfaces and security groups to further isolate (Addition of DT worker host can be performed later). You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering.

Introduction. * Internal networks are physically separate from external networks where clients can access. connect string to skip hostname validation: As always you can create an own certificate for the client and copy it to sapcli.pse instead of using the server sapsrv.pse. It's a hidden feature which should be more visible for customers. Step 1 . Since NSE is a capability of the core HANA server, using NSE eliminates the limitations of DT that you highlighted above. (4) site1 is repaired and joined the replication as secondary(sync to site2, site3 need unregistered from site2 and re-registered to site1). Its purpose is to extend SAP HANA memory with a disk-centric columnar store (as opposed to the SAP HANA in-memory store). (more details in 8.) HI DongKyun Kim, thanks for explanation . SAP HANA system replication provides the possibility to copy and continuously synchronize a SAP HANA database to a secondary location in the same or another data center. Internal communication is configured too openly path for the system replication. provide additional, dedicated capacity for Amazon EBS I/O. Now you have to go to the HANA Cockpit Manager to change the registered resource to use SSL. * as public network and 192.168.1. If set on the primary system, the loaded table information is resolution is working by creating entries in all applicable host files or in the Domain These are called EBS-optimized the global.ini file is set to normal for both systems. Unregisters a system replication site on a primary system. Dynamic tiering option can be deployed in two ways: You can install SAP HANA and SAP HANA dynamic tiering each on a dedicated server (referred to as a dedicated host deployment) or on the same server (referred to as a same host deployment). Figure 11: Network interfaces and security groups. Recently we started receiving the alerts from our monitoring tool: * Dedicated network for system replication: 10.5.1. # 2021/09/09 updated parameter info: is/local_addr thx @ Matthias Sander for the hint Disables the preload of column table main parts. In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. 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 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.
