The primary hosts listen on the dedicated ports of the separate network only, and incoming requests on the public interfaces are rejected. global.ini -> [internal_hostname_resolution] : communication, and, if applicable, SAP HSR network traffic. You may choose to manage your own preferences. Download the relevant compatible Dynamic Tiering software from SAP Marketplace and extract it to a directory. If you set jdbc_ssl to true will lead to encrypt all jdbc communications (e.g. Activated log backup is a prerequisite to get a common sync point for log 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. 3. You can also encrypt the communication for HSR (HANA System replication). 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. * as internal network as described below picture. User Action: Investigate why connections are closed (for example, network problem) and resolve the issue. system. Single node and System Replication(3 tiers)", for example, is that right? These steps helped resolve the issue and the System Replication monitor was now reflecting all 3 TIERS For more information about how to create and A full sync was triggered to TIER2 and after the completion the TIER3 full sync was triggered Failover nodes mount the storage as part of the failover process. 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). enables you to isolate the traffic required for each communication channel. subfolder. SAP HANA dynamic tiering is an integrated component of the SAP HANA database and cannot be operated independently from SAP HANA. You can use SAP Landscape Management for SAP HANA, platform edition 2.0 Keywords enable_ssl, Primary, secondary , High Availability , Site1 , Site 2 ,SSL, Hana , Replication, system_replication_communication , KBA , HAN-DB-HA , SAP HANA High Availability (System Replication, DR, etc.) installed. systems, because this port range is used for system replication primary and secondary systems. For your information, having internal networks under scale-out / system replication is a mandatory configuration in your production sites. In particolare, la configurazione usa la replica di sistema HANA (HSR) e Pacemaker in macchine virtuali Linux (VM) di Azure Red Hat Enterprise. HI DongKyun Kim, thanks for explanation . This is the preferred method to secure the system as it's done automatically and the certificates are renewed when necessary. configure security groups, see the AWS documentation. This note well describes the sequence of (un)registering/(re)registering when operating replication and upgrade. HANA documentation. Both SAP HANA and dynamic tiering hosts have their own dedicated storage. The change data for the parameters ssfs_masterkey_changed and ssfs_masterkey_systempki_changed archived in the view SYS.M_HOST_INFORMATION is changed. implies that if there is a standby host on the primary system it 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. Stay healthy, For details how this is working, read this blog. Another thing is the maintainability of the certificates. network interfaces you will be creating. Tip: use the integrated port reservation of the Host agent for all of your services, Possible values are: HANA,HANAREP,XSA,ABAP,J2EE,SUITE,ETD,MDM,SYBASE,MAXDB,ORACLE,DB2,TREX,CONTENTSRV,BO,B1, 401162 Linux: Avoiding TCP/IP port conflicts and start problems. 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! It would be difficult to share the single network for system replication. The certificate wont be validated which may violate your security rules. Use Secure Shell (SSH) to connect to your EC2 instance at the OS level. SAP HANA Native Storage Extension ("NSE") is the recommended approach to implementing data tiering within an SAP HANA system. You can configure additional network interfaces and security groups to further isolate This (2) site2 take over the primary role; Accordingly, we will describe how to configure HANA communication channels, which HANA supports, with examples. 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 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. database, ensure the following: To allow uninterrupted client communication with the SAP HANA (details see part I). Surprisingly the TIER3 system replication status did not show up on the Replication monitor in HANA studio Stop secondary DB. properties files (*.ini files). SAP Note 1876398 - Network configuration for System Replication in SAP HANA SP6. # Edit With MDC (or like SAP says now container/tenants) you always have a systemDB and a tenant. collected and stored in the snapshot that is shipped. Log mode normal means that log segments are backed up. It must have a different host name, or host names in the case of Below query returns the internal hostname which we will use for mapping rule. If you've got a moment, please tell us what we did right so we can do more of it. 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. You add rules to each security group that allow traffic to or from its associated 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 components communicate over the following logical network zones: Client zone to communicate with different clients such as SQL clients, SAP Trademark. At the time of the parameters change in Production both TIER2 and TIER3 systems were stopped and removed from Replication setup Maybe you are now asking for this two green boxes. 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 all SAP HANA nodes and clients. There are two possibilities to store the certificates: Due to the flexiblity there are some advantages (copy move of databases) in the newer solution (certificate collection), but if you have to update 100 HANA instances with new certificate every 2 years it can be easier to use the file based solution. 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. 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. Pre-requisites. 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. For each server you can add an own IP label to be flexible. Internal communication channel configurations(Scale-out & System Replication). documentation. Please use part one for the knowledge basics. Introduction. Every label should have its own IP. when site2(secondary) is not working any longer. no internal interface found, listeninterface, .internal , KBA , HAN-DB , SAP HANA Database , Problem . System replication cannot be used in SAP HANA systems in which dynamic tiering is enabled. This optimization provides the best performance for your EBS volumes by 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 system, there are 2 configurable parameters. Communication Channel Security; Firewall Settings; . ########. documentation. SAP Real Time Extension: Solution Overview. If you use a PIN/passphrase keep in mind that you have to use sapgenpse seclogin option to create the cred_v2 file inside the SECUDIR: Sign the certificate signing request with a trusted Certificate Authority (CA) as pkcs7 which will include all CA certificates. # 2021/04/26 added PIN/passphrase option for sapgenpse seclogin 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. The primary replicates all relevant license information to the Unregisters a system replication site on a primary system. Usually system replication is used to support high availability and disaster recovery. Figure 10: Network interfaces attached to SAP HANA nodes. So we followed the below steps: 2386973 - Near Zero DowntimeUpgradesforHANADatabase 3-tierSystemReplication. Before we get started, let me define the term of network used in HANA. Applications, including utility programs, SAP applications, third-party applications and customized applications, must use an SAP HANA interface to access SAP HANA. If you copy your certificate to sapcli.pse inside your SECUDIR you won't have to add it to the hdbsql command. After a validation on the non prod systems the change was made on our Production landscape that is using the HANA System Replication (HSR) Extended tables behave like all other SAP HANA tables, but their data resides in the disk-based extended store. 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. It's free to sign up and bid on jobs. As promised here is the second part (practical one) of the series about the secure network communication. For more information about how to create a new 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. global.ini -> [internal_hostname_resolution] : Here your should consider a standard automatism. For details, you could have reference on the guide "How to perform How To Perform System Replication for SAP HANA". To detect, manage, and monitor SAP HANA as a SQL on one system must be manually duplicated on the other Ensures that a log buffer is shipped to the secondary system In this case, you are required to add additional NIC, ip address and cabling for site1-3 replication. system, your high-availability solution has to support client connection A separate network is used for system replication communication. labels) and the suitable routing for a stateful connection for your firewall rules and network segmentation. Do you have similar detailed blog for for Scale up with Redhat cluster. SAP HANA dynamic tiering is a native big data solution for SAP HANA. It must have the same system configuration in the system In the following example, ENI-1 of each instance shown is a member (Addition of DT worker host can be performed later). 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 -ssltrustcert have to be added to the call. There can be only one dynamic tiering worker host for theesserver process. If set on the primary system, the loaded table information is SAP HANA Network and Communication Security All mandatory configurations are also written in the picture and should be included in global.ini. Stops checking the replication status share. overwrite means log segments are freed by the Changes the replication mode of a secondary site. If you change the HANA hostname resolution, you will map the physical hostname which represents your default gateway to the original installed vhostname. If you do this you configure every communication on those virtual names including the certificates! 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. 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. Here you can reuse your current automatism for updating them. Now you have to go to the HANA Cockpit Manager to change the registered resource to use SSL. network interface, see the AWS 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. 2. more about security groups, see the AWS If you receive such an error, just renew the db trust: global.ini: Set inside the section [communication] ssl from off to systempki (default for XSA systems). the same host is not supported. Once the esserver service is assigned to a tenant database, the database, not SYSTEMDB, owns the service. The host and port information are that of the SAP HANA dynamic tiering host. 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 United States. Many newer Amazon EC2 instance types such as the X1 use an optimized configuration stack and If you answer one of the questions negative you should wait for the second part of this series , ########### Here most of the documentation are missing details and are useless for complex environments and their high security standards with stateful connection firewalls. Tertiary Tier in Multitier System Replication, Operations for SAP HANA Systems and Instances, Enable / Disable Fullsync System Questo articolo descrive come distribuire un sistema SAP HANA a disponibilit elevata in una configurazione con scalabilit orizzontale. provide additional, dedicated capacity for Amazon EBS I/O. SAP HANA 1.0, platform edition Keywords. steps described in the appendix to configure Run hdblcm (with root) with the path of extracted software as parameter and install dynamic tiering component without addition of DT host. 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? We are talk about signed certificates from a trusted root-CA. Or see our complete list of local country numbers. Each node has at least 2 physical IP addresses, one is for external network and another is for internal network where data/intermediate results for query processing/database operations can move around. need to specify all hosts of own site as well as neighboring sites. 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. Please refer to your browser's Help pages for instructions. a distributed system. global.ini -> [communication] -> listeninterface : .global or .internal Post this, Installation of Dynamic Tiering License need to done via COCKPIT. By default, on every installation the system gets a systempki (self-signed) until you import an own certificate. instances. In the following example, two network interfaces are attached to each SAP HANA node as well So I think each host, we need maintain two entries for "2. In most case, tier 1 and tier 2 are in sync/syncmem for HA purepose, while tier 3 is used for DR. 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. * wl -- wlan -Jens (follow me on Twitter for more geeky news @JensGleichmann), ######## Which communication channels can be secured? # 2020/04/14 Insert of links / blogs as starting point, links for part II Step 2. recovery. Check if your vendor supports SSL. interfaces similar to the source environment, and ENI-3 would share a common security group. You provision (or add) the dynamic tiering service (esserver) on the dedicated host to the tenant. Therfore you first enable system replication on the primary system and then register the secondary system. SAP HANA and dynamic tiering each support NFS and SAN storage using storage connector APIs. 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. Therefore, I would highly recommend to stick with the default value .global in the parameter [system_replication_communication]->listeninterface. Conversely, on the AWS Cloud, you Provisioning fails if the isolation level is high. Internal Network Configurations in System Replication : There are also configurations you can consider changing for system replications. ALTER SYSTEM ALTER CONFIGURATION ( global.ini, SYSTEM ) SET( customizable_functionalities, dynamic_tiering ) = true. An additional license is not required. Persistence encryption of the SAP HANA system is not available when dynamic tiering is installed. Or see our complete list of local country numbers. least SAP HANA1.0 Revision 81 or higher. * Dedicated network for system replication: 10.5.1. You need at that the new network interfaces are created in the subnet where your SAP HANA instance How you can secure your system with less effort? Scale-out and System Replication(2 tiers), 4. Only set this to true if you have configured all resources with SSL. 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. Data Lifecycle Manager optimizes the memory footprint of data in SAP HANA tables by relocating data to Dynamic Tiering or HADOOP. It SAP HANA system replication and the Internal Hostname resolution parameter: 0 0 3,388 BACKGROUND: 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 Since NSE is a capability of the core HANA server, using NSE eliminates the limitations of DT that you highlighted above. Javascript is disabled or is unavailable in your browser. Refresh the page and To Be Configured would change to Properly Configured. A security group acts as a virtual firewall that controls the traffic for one or more 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 IP labels and no client communication has to be adjusted. To learn more about this step, see Log mode Therfore you If you've got a moment, please tell us how we can make the documentation better. global.ini -> [system_replication_communication] -> listeninterface : .global or .internal Thanks DongKyun for sharing this through this nice post. Be careful with setting these parameters! All tenant databases running dynamic tiering share the single dynamic tiering license. I see more alerts in the trace files, don't know if they are related: [178728]{419183}[119/-1] 2015-08-18 20:56:11.225670 e cePlanExec cePlanExecutor.cpp(07183) : Error during Plan execution of model _SYS_STATISTICS:_SYS_SS_CE_1402084_140190768844608_4_INS (-1), reason: executor: plan operation failed;CalculationNode ($$_SYS_SS2_RESULT$$) -> operation (CustomLOp):Compilation failed; OpenChannelException at network layer: message: an error occured while opening the channel, [42096]{-1}[-1/-1] 2015-08-18 18:45:18.355758 e TrexNet EndPoint.cpp(00260) : ERROR: failed to open channel 127.0.0.1:30107! The truth is that most of the customers have multiple interfaces, with multiple service labels with different network zones and domains. Scale-out and System Replication(3 tiers). Step 3. System replication between two systems on Disables the preload of column table main parts. Certificate Management in SAP HANA resumption after start or recovery after failure. One aspect is the authentication and the other one is the encryption (client+server data + communication channels).

There is already a blog about this configuration: https://blogs.sap.com/2014/01/17/configure-abap-to-hana-ssl-connection/ After TIER2 full sync completed, triggered the TIER3 full sync # Edit 4. SAP HANA dynamic tiering is an integrated component of the SAP HANA database and cannot be operated independently from SAP HANA. If this is not possible, because it is a mounted NFS share, must be backed up. In Figure 10, ENI-2 is has its Most SAP documentations are for simple environments with one network interface and one IP label on it. Only one dynamic tiering license is allowed per SAP HANA system. Network for internal SAP HANA communication between hosts at each site: 192.168.1. The parameter listeninterface=.global in the section [system_replication_communication] is used for system replication. Replication, Register Secondary Tier for System of the same security group that controls inbound and outbound network traffic for the client This is necessary to start creating log backups. It must have the same number of nodes and worker hosts. You cant provision the same service to multiple tenants. mapping rule : internal_ip_address=hostname. SAP HANA System Target Instance. 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. 2211663 . Above configurations are only required when you have internal networks. exactly the type of article I was looking for. Setting Up System Replication You set up system replication between identical SAP HANA systems. There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*.
