Each tenant requires a dedicated dynamic tiering host. # Edit On every installation of an SAP application you have to take care of this names. These steps helped resolve the issue and the System Replication monitor was now reflecting all 3 TIERS If this is not possible, because it is a mounted NFS share, If you plan to use storage connector APIs, you must configure the multipath.conf and global.ini files before installation. The systempki should be used to secure the communication between internal components. SAP HANA System Target Instance. * In the first example, the [system_replication_communication]listeninterface parameter has been set to .global and only the hosts of the neighboring replicating site are specified. SQL on one system must be manually duplicated on the other -Jens (follow me on Twitter for more geeky news @JensGleichmann), ######## As you create each new network interface, associate it with the appropriate mapping rule : system_replication_internal_ip_address=hostname, 1. 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 Refresh the page and To Be Configured would change to Properly Configured. Persistence encryption of the SAP HANA system is not available when dynamic tiering is installed. the OS to properly recognize and name the Ethernet devices associated with the new As you may read between the lines Im not a fan of authorization concepts. Copy the commands and deploy in SQL command. SAP HANA Tenant Database . A security group acts as a virtual firewall that controls the traffic for one or more Usually system replication is used to support high availability and disaster recovery. Updates parameters that are relevant for the HA/DR provider hook. Please provide your valuable feedback and please connect with me for any questions. tables are actually preloaded there according to the information The host name specified here is used to verify the identity of the server instead of the host name with which the connection was established. Disables the preload of column table main parts. least SAP HANA1.0 Revision 81 or higher. Pipeline End-to-End Overview. Terms of use | Here your should consider a standard automatism. 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. Pre-requisites. Name System (DNS). more about security groups, see the AWS For scale-out deployments, configure SAP HANA inter-service communication to let # Inserted new parameters from 2300943 System replication between two systems on To set it up is one task, to maintain and operate it another.

The connection parameters for ODBC-based connections can also be used to configure TLS/SSL for connections from ABAP applications to SAP HANA using the SAP Database Shared Library (DBSL). The use of TLS/SSL should be standard for every installation, but to use it on every SAP instance you have to read a lot of documentation and sometimes the provided details are not helpful for complex environments. So we followed the below steps: Maybe you are now asking for this two green boxes. , Problem. 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. HANA XSA port specification via mtaext: SAP note 2389709 - Specifying the port for SAP HANA Cockpit before installation Needed PSE's and their usage. In particolare, la configurazione usa la replica di sistema HANA (HSR) e Pacemaker in macchine virtuali Linux (VM) di Azure Red Hat Enterprise. # Edit Surprisingly the TIER3 system replication status did not show up on the Replication monitor in HANA studio We can install DLM using Hana lifecycle manager as described below: Click on to be configured. In HANA studio this process corresponds to esserver service. When you launch an instance, you associate one or more security groups with the But keep in mind that jdbc_ssl parameter has no effect for Node.js applications! You need a minimum SP level of 7.2 SP09 to use this feature. You cant provision the same service to multiple tenants. Early Watch Alert shows a red alert at section " SAP HANA Network Settings for System Replication Communication (listeninterface) ": SAP Knowledge Base Article - Preview 2777802-EWA Alert: TLS encrypted communication expected (when listeninterface = .global) Symptom In most case, tier 1 and tier 2 are in sync/syncmem for HA purepose, while tier 3 is used for DR.

You may choose to manage your own preferences. the secondary system, this information is evaluated and the 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 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. United States. I hope this little summary is helping you to understand the relations and avoid some errors and long researches. as in a separate communication channel for storage. It must have the same system configuration in the system For instance, third party tools like the backup tool via backint are affected. The primary hosts listen on the dedicated ports of the separate network only, and incoming requests on the public interfaces are rejected. mapping rule : internal_ip_address=hostname. Provisioning fails if the isolation level is high. You can use SAP Landscape Management for 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. EC2 instance in an Amazon Virtual Private Cloud (Amazon VPC). 1. systems, because this port range is used for system replication 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. Many newer Amazon EC2 instance types such as the X1 use an optimized configuration stack and Find SAP product documentation, Learning Journeys, and more. (Addition of DT worker host can be performed later). RFC Module. Above configurations are only required when you have internal networks. Unless you are using SAPGENPSE, do not password protect the keystore file that contains the servers private key. 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! You need at all SAP HANA nodes and clients. Wonderful information in a couple of blogs!! Log mode 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. You can copy the certificate of the HANA database to the application server but you dont need to (HANA on one Server Tier 2). operations or SAP HANA processes as required. isolation. Post this, Installation of Dynamic Tiering License need to done via COCKPIT. To use the Amazon Web Services Documentation, Javascript must be enabled. reason: (connection refused). It differs for nearly each component which makes it pretty hard for an administrator. For more information, see SAP HANA Database Backup and Recovery. when site2(secondary) is not working any longer. Starts checking the replication status share. Attach the network interfaces you created to your EC2 instance where SAP HANA is system. HANA System Replication, SAP HANA System Replication If you set jdbc_ssl to true will lead to encrypt all jdbc communications (e.g. 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. You use this service to create the extended store and extended tables. And you need to change the parameter [communication]->listeninterface to .internal and add internal network entries as followings. You have assigned the roles and groups required. You just have to set the dbs/hdb/connect_property parameter to the correct value: In some cases, you may receive an error if you force the use of TLS/SSL: You have to set some tricky parameter due to the default gateway of the Linux server. Ensures that a log buffer is shipped to the secondary system communication, and, if applicable, SAP HSR network traffic. connection recovery after disaster recovery with network-based IP is deployed. Perform backup on primary. Communication Channel Security; Firewall Settings; . (3) site3 is still registered to the site2 (as it's not impacted, async only as remote DR); Privacy | It also means for SAP Note 2386973, the original multitier setup is(SiteA --sync--> SiteB --async--> SiteC), after step 9, the setup is most likely (SiteB--async-->SiteC; SiteA down), and the target multitier setup is (SiteB --sync--> SiteA --async--> SiteC), and then the steps 15-19 can be skipped, and adjusted steps 20-22, to registered SiteC to SiteA. resumption after start or recovery after failure. Thanks a lot for sharing this , it's a excellent blog . Not sure up to which revision the "legacy" properties will work. steps described in the appendix to configure Network for internal SAP HANA communication: 192.168.1. Thanks DongKyun for sharing this through this nice post. Otherwise, the system performance or expected response time might not be guaranteed due to the limited network bandwidth. Only set this to true if you have configured all resources with SSL. overwrite means log segments are freed by the Replication, Register Secondary Tier for System 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. automatically applied to all instances that are associated with the security group. So, the easiest way is to use the XSA set-certificate command: Afterwards check your system with the diagnose function. To change the TLS version and the ciphers for the XSA you have to edit the xscontroller.ini.

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. 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. Scale-out and System Replication(3 tiers). When set, a diamond appears in the database column. 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. Please refer to your browser's Help pages for instructions. For your information, having internal networks under scale-out / system replication is a mandatory configuration in your production sites. System Monitoring of SAP HANA with System Replication. 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 provide additional, dedicated capacity for Amazon EBS I/O. Recently we started receiving the alerts from our monitoring tool: Is it possible to switch a tenant to another systemDB without changing all of your client connections? Keep the tenant isolation level low on any tenant running dynamic tiering. To learn more about this step, see System replication cannot be used in SAP HANA systems in which dynamic tiering is enabled. To configure your logical network for SAP HANA, follow these steps: Create new security groups to allow for isolation of client, internal SAP HANA SSFS Master Encryption Key The SSFS master encryption key must be changed in accordance with SAP Note 2183624. Overview. Determine which format your key file has with a look into it: If it is a PKCS#12 format you have to follow this steps (there are several ways, just have a look at the openssl documentation): a) Export the keys in PKCS#12 transfer format: The HANA DB has to be online. is configured to secure SAP HSR traffic to another Availability Zone within the same Region. Otherwise, please ignore this section. global.ini -> [communication] -> listeninterface : .global or .internal I'm getting this email alert from the HANA tenant database: Alert Name : Connection between systems in system replication setup, Details : At 2015-08-18 18:35:45.0000000 on hostp01:30103; Site 2: Communication channel closed. 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. SAP is using mostly one certificate for all components (host agent, DAA, SystemDB, Tenant) which belongs to the physical hostname (systempki). savepoint (therefore only useful for test installations without backup and the global.ini file is set to normal for both systems. About this page This is a preview of a SAP Knowledge Base Article. site1(primary) becomes standalone and site3(dr) is required to be promoted as secondary site temporarily while site2 is being repaired/replaced in data center. security group you created in step 1. -ssltrustcert have to be added to the call. * Dedicated network for system replication: 10.5.1.

(more details in 8.) SAP Host Agent must be able to write to the operations.d Chat Offline. Contact us. In general, there is no needs to add site3 information in site1, vice versa. 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. SAP HANA Network and Communication Security You set up system replication between identical SAP HANA systems. More and more customers are attaching importance to the topic security. Its purpose is to extend SAP HANA memory with a disk-centric columnar store (as opposed to the SAP HANA in-memory store). Extended tables behave like all other SAP HANA tables, but their data resides in the disk-based extended store. The latest release version of DT is SAP HANA 2.0 SP05. You can also encrypt the communication for HSR (HANA System replication). Log mode normal means that log segments are backed up. Dynamic tiering enhances SAP HANA with large volume, warm data management capability. The datavolumes_es and logvolumes_es paths are defined in the SYSTEMDB globlal.ini file at the system level but are applied at the database level. subfolder. 2685661 - Licensing Required for HANA System Replication. The new rules are Contact us. different logical networks by specifying multiple private IP addresses for your instances. When you use SAP HANA to place hot data in SAP HANA in-memory tables, and warm data in extended tables, highest value data remains in memory, and cooler less-valuable data is saved to the extended store. It would be difficult to share the single network for system replication. ########. The host and port information are that of the SAP HANA dynamic tiering host. Dynamic tiering adds smart, disk-based extended storage to your SAP HANA database. There can be only one dynamic tiering worker host for theesserver process. documentation. Have you identified all clients establishing a connection to your HANA databases? need not be available on the secondary system. At the time of the parameters change in Production both TIER2 and TIER3 systems were stopped and removed from Replication setup Prerequisites You comply all prerequisites for SAP HANA system replication. Below query returns the internal hostname which we will use for mapping rule. By default, on every installation the system gets a systempki (self-signed) until you import an own certificate. SAP HANA communicate over the internal network. In the following example, two network interfaces are attached to each SAP HANA node as well You may choose to manage your own preferences. This blog provides an overview of considerations and recommended configurations in order to manage internal communication channels among scale-out / system replications. Activated log backup is a prerequisite to get a common sync point for log Figure 12: Further isolation with additional ENIs and security 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. Configure SAP HANA hostname resolution to let SAP HANA communicate over the We are actually considering the following scenarios: If you copy your certificate to sapcli.pse inside your SECUDIR you won't have to add it to the hdbsql command. * 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/. the same host is not supported. Both SAP HANA and dynamic tiering hosts, including standby hosts, use storage APIs to access the devices. system. 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 HANA supports asynchronous and synchronous replication modes. ENI-3 If you change the HANA hostname resolution, you will map the physical hostname which represents your default gateway to the original installed vhostname. Actually, in a system replication configuration, the whole system, i.e. Failover nodes mount the storage as part of the failover process. After TIER2 full sync completed, triggered the TIER3 full sync 3.
