Accordingly, we will describe how to configure HANA communication channels, which HANA supports, with examples. The last step is the activation of the System Monitoring. resumption after start or recovery after failure. mapping rule : internal_ip_address=hostname. Before drawing the architecture, I hope this blog would help to get better understanding of networks required in HANA database regardless of the complexity. Removes system replication configuration. Use Secure Shell (SSH) to connect to your EC2 instance at the OS level. inter-node communication as well as SAP HSR network traffic. (details see part I). SAP HANA components communicate over the following logical network zones: Client zone to communicate with different clients such as SQL clients, SAP instances. Configure SAP HANA hostname resolution to let SAP HANA communicate over the So site1 & site3 won't meet except the case that I described. 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. collected and stored in the snapshot that is shipped. 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 Persistence encryption of the SAP HANA system is not available when dynamic tiering is installed. And there must be manual intervention to unregister/reregister site2&3. If you have to install a new OS version you can setup your new environment and switch the application incl. Updates parameters that are relevant for the HA/DR provider hook. all SAP HANA nodes and clients. For instance, third party tools like the backup tool via backint are affected. The new rules are 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). SAP HANA System Target Instance. Certificate Management in SAP HANA Each tenant requires a dedicated dynamic tiering host. For instance, you have 10.0.1. received on the loaded tables. steps described in the appendix to configure * The hostname in below refers to internal hostname in Part1. Figure 10: Network interfaces attached to SAP HANA nodes. So we followed the below steps: 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. The instance number+1 must be free on both So, the easiest way is to use the XSA set-certificate command: Afterwards check your system with the diagnose function. For more information, see Standard Permissions. After TIER2 full sync completed, triggered the TIER3 full sync * en -- ethernet You can use SAP Landscape Management for On every installation of an SAP application you have to take care of this names. It's free to sign up and bid on jobs. SAP Data Intelligence (prev. Have you identified all clients establishing a connection to your HANA databases? On HANA you can also configure each interface. # 2020/04/14 Insert of links / blogs as starting point, links for part II You need a minimum SP level of 7.2 SP09 to use this feature. 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. First time, I Know that the mapping of hostname to IP can be different on each host in system replication relationship. We are actually considering the following scenarios: 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). Replication, Register Secondary Tier for System Are you already prepared for changing the server due to hardware change / OS upgrade with a virtual hostname concept? when site2(secondary) is not working any longer. mapping rule : internal_ip_address=hostname. The secondary system must meet the following criteria with respect to the number. A security group acts as a virtual firewall that controls the traffic for one or more secondary. We know for step(4), there could be one more takeover, and then site1 will become new primary, but since site1 and site2 has the same capacity, it's not necessary to introduce one more short downtime for production, right? database, ensure the following: To allow uninterrupted client communication with the SAP HANA To learn Deploy SAP Data Warehouse Foundation (Data Lifecycle Manager) Delivery Unit on SAP HANA. Usually, tertiary site is located geographically far away from secondary site. global.ini -> [system_replication_hostname_resolution] : You need at network interface in the remainder of this guide), you can create SAP HANA communicate over the internal network. the same host is not supported. Understood More Information Visit SAP Support Portal's SAP Notes and KBA Search. Extracting the table STXL. The cleanest way is the Golden middle option 2. 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. If this is not possible, because it is a mounted NFS share, Internal communication is configured too openly Which communication channels can be secured? 2487639 HANA Basic How-To Series HANA and SSL MASTER KBA Step 1 . This will speed up your login instead of using the openssl variant which you discribed. Once the esserver service is assigned to a tenant database, the database, not SYSTEMDB, owns the service. 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. If you plan to use storage connector APIs, you must configure the multipath.conf and global.ini files before installation. 2386973 - Near Zero DowntimeUpgradesforHANADatabase 3-tierSystemReplication. You can copy the certificate of the HANA database to the application server but you dont need to (HANA on one Server Tier 2). # 2021/09/09 updated parameter info: is/local_addr thx @ Matthias Sander for the hint 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. The change data for the parameters ssfs_masterkey_changed and ssfs_masterkey_systempki_changed archived in the view SYS.M_HOST_INFORMATION is changed. To set it up is one task, to maintain and operate it another. This option requires an internal network address entry. 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. On AS ABAP server this is controlled by is/local_addr parameter. properties files (*.ini files). HANA database explorer) with all connected HANA resources! Provisioning dynamic tiering service to a tenant database. 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. Do you have similar detailed blog for for Scale up with Redhat cluster. 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!

Here most of the documentation are missing details and are useless for complex environments and their high security standards with stateful connection firewalls. 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. Failover nodes mount the storage as part of the failover process. overwrite means log segments are freed by the For your information, I copy sap note Wonderful information in a couple of blogs!! * sl -- serial line IP (slip) HANA System Replication, SAP HANA System Replication global.ini -> [communication] -> listeninterface : .global or .internal communications. instances. A service in this context means if you have multiple services like multiple tenants on one server running. Amazon EBS-optimized instances can also be used for further isolation for storage I/O. 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. can use elastic network interfaces combined with security groups to achieve this network These steps helped resolve the issue and the System Replication monitor was now reflecting all 3 TIERS 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. 1. * You have installed internal networks in each nodes. For details how this is working, read this blog. Thanks for letting us know we're doing a good job! The BACKINT interface is available with SAP HANA dynamic tiering. There is already a blog about this configuration: https://blogs.sap.com/2014/01/17/configure-abap-to-hana-ssl-connection/ documentation. shipping between the primary and secondary system. Therefore, I would highly recommend to stick with the default value .global in the parameter [system_replication_communication]->listeninterface. well as for SAP HSR, Storage zone to persist SAP HANA data in the storage infrastructure for Data Lifecycle Manager optimizes the memory footprint of data in SAP HANA tables by relocating data to Dynamic Tiering or HADOOP. global.ini -> [communication] -> listeninterface : .global or .internal The XSA can be offline, but will be restarted (thanks for the hint Dennis). Started the full sync to TIER2 To configure your logical network for SAP HANA, follow these steps: Create new security groups to allow for isolation of client, internal Network for internal SAP HANA communication: 192.168.1. recovery). Here it is pretty simple one option is to define manually some command line options: cp /usr/sap/SID/HDB00/hostname/sec/sapsrv.pse /usr/sap/SID/HDB00/hostname/sec/sapcli.pse. But keep in mind that jdbc_ssl parameter has no effect for Node.js applications! In the step 5, it is possible to avoid exporting and converting the keys. Follow the We are talk about signed certificates from a trusted root-CA. Dynamic tiering is also supported by the Data Lifecycle Manager (DLM), an SAP HANA XS-based tool to relocate data from SAP HANA memory to alternate storage locations such as the dynamic tiering extended store, SAP HANA extension nodes, or Hadoop/Vora. 2475246 How to configure HANA DB connections using SSL from ABAP instance. So I think each host, we need maintain two entries for "2. before a commit takes place on the local primary system. the IP labels and no client communication has to be adjusted. Maybe you are now asking for this two green boxes. If you set jdbc_ssl to true will lead to encrypt all jdbc communications (e.g. minimizing contention between Amazon EBS I/O and other traffic from your instance. There can be only one dynamic tiering worker host for theesserver process. Step 1. 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. # Edit Thank you Robert for sharing the current developments on "DT", Alerting is not available for unauthorized users, Right click and copy the link to share this comment. 3.

Comprehensive and complete, thanks a lot. In particolare, la configurazione usa la replica di sistema HANA (HSR) e Pacemaker in macchine virtuali Linux (VM) di Azure Red Hat Enterprise. It must have the same number of nodes and worker hosts. 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. to use SSL [part II], Configure HDB parameters for high security [part II], Configure XSA with TLS and cipher for high security [part II], Import certificate to host agent [part II], Pros and Cons certification collections [part II], Will show your certificate for your domain(s), Check the certificate: sapgenpse get_my_name -p cert.pse, Replace the sapsrv.pse, SAPSSLS.pse and SAPSSLC.pse with the created cert.pse, the application server connection via SQLDBC have to set up to be secure, HANA Cockpit connections have to set up to be secure, Local hdbsql connections have to be set up for encryption, sslValidateCertificate = false => will not validate the certificate, sslHostNameInCertificate = => will overwrite the calling hostname, configure the hostname mapping inside the HANA, the other one to copy the sapsrv.pse to the sapcli.pse, Create the certificate on base of the vhostname of the server, Copy the *.pse as SAPSSLS.pse to /usr/sap/hostctrl/exe/sec/, use sapgenpse seclogin option as root (with proper environment means SECUDIR variable) when you have specified a PIN/passphrase, inside the database => certificate collection. documentation. Keep the tenant isolation level low on any tenant running dynamic tiering. Here we talk about the client within the HANA client executable. Stay healthy, operations or SAP HANA processes as required. 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. labels) and the suitable routing for a stateful connection for your firewall rules and network segmentation. Storage snapshots cannot be prepared in SAP HANA systems in which dynamic tiering is enabled. Its purpose is to extend SAP HANA memory with a disk-centric columnar store (as opposed to the SAP HANA in-memory store). You can also encrypt the communication for HSR (HANA System replication).

An additional license is not required. You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering. 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 reason: (connection refused). Pipeline End-to-End Overview. But still some more options e.g. SAP HANA dynamic tiering adds the SAP HANA dynamic tiering service (esserver) to your SAP HANA system. SAP Note 1834153 . need not be available on the secondary system. In a traditional, bare-metal setup, these different network zones are set up by having In this case, you are required to add additional NIC, ip address and cabling for site1-3 replication. 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. 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. The OS process for the dynamic tiering host is hdbesserver, and the service name is esserver. 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. Share, Unregister Secondary Tier from System Replication, Unregister System Replication Site on 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.) System replication cannot be used in SAP HANA systems in which dynamic tiering is enabled.
