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. Comprehensive and complete, thanks a lot. The new rules are systems, because this port range is used for system replication Linux' predictable network device names aka default network was "eth0" is now still predictably used as "enp1s0" with different rule set. In multiple-container systems, the system database and all tenant databases An additional license is not required. You can use SAP Landscape Management for We are actually considering the following scenarios: 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. Setting up SAP data connection. 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. Make sure Thanks for the further explanation. You have assigned the roles and groups required. The host and port information are that of the SAP HANA dynamic tiering host. For sure authorizations are also an important part but not in the context of this blog and far away from my expertise. network interfaces you will be creating. Check if your vendor supports SSL. 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 Alerting is not available for unauthorized users, Right click and copy the link to share this comment. The XSA can be offline, but will be restarted (thanks for the hint Dennis). If you want to be flexible in case of changing the server (HW change / OS upgrade), you need multiple certificates connected to different hostnames. network. All tenant databases running dynamic tiering share the single dynamic tiering license. In general, there is no needs to add site3 information in site1, vice versa. 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. groups. Here we talk about the client within the HANA client executable. Surprisingly the TIER3 system replication status did not show up on the Replication monitor in HANA studio exactly the type of article I was looking for. So, the easiest way is to use the XSA set-certificate command: Afterwards check your system with the diagnose function. For more information, see SAP Note 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. In this example, the target SAP HANA cluster would be configured with additional network The primary replicates all relevant license information to the must be backed up. resolution is working by creating entries in all applicable host files or in the Domain thank you for this very valuable blog series! 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. secondary. recovery. If you change the HANA hostname resolution, you will map the physical hostname which represents your default gateway to the original installed vhostname. To use the Amazon Web Services Documentation, Javascript must be enabled. (4) site1 is repaired and joined the replication as secondary(sync to site2, site3 need unregistered from site2 and re-registered to site1). SAP HANA Network and Communication Security 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. Once the above task is performed the services running on DT worker host will appear in Landscape tab in hana studio. security group you created in step 1. Single node and System Replication(3 tiers), 3. Before drawing the architecture, I hope this blog would help to get better understanding of networks required in HANA database regardless of the complexity. Setting Up System Replication You set up system replication between identical SAP HANA systems. The OS process for the dynamic tiering host is hdbesserver, and the service name is esserver. Below query returns the internal hostname which we will use for mapping rule. Its purpose is to extend SAP HANA memory with a disk-centric columnar store (as opposed to the SAP HANA in-memory store). For more information about how to attach a network interface to an EC2 Global Network Network and Communication Security. General Prerequisites for Configuring SAP Overview. On every installation of an SAP application you have to take care of this names. * Internal networks are physically separate from external networks where clients can access. Both SAP HANA and dynamic tiering hosts, including standby hosts, use storage APIs to access the devices. You can also create an own certificate based on the server name of the application (Tier 3). Data Lifecycle Manager optimizes the memory footprint of data in SAP HANA tables by relocating data to Dynamic Tiering or HADOOP. This optimization provides the best performance for your EBS volumes by 4. of ports used for different network zones. The latest release version of DT is SAP HANA 2.0 SP05. By default, this enables security and forces all resources to use ssl. This option requires an internal network address entry. 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. 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. The values are visible in the global.ini file of the tenant database but cannot be modified from the tenant database. Step 3. Checks whether the HA/DR provider hook is configured. 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). But still some more options e.g. 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. Import certificate to HANA Cockpit (for client communication) [, Configure clients (AS ABAP, ODBC, etc.) # Edit When you launch an instance, you associate one or more security groups with the as in a separate communication channel for storage. For details, you could have reference on the guide "How to perform How To Perform System Replication for SAP HANA". Deploy SAP Data Warehouse Foundation (Data Lifecycle Manager) Delivery Unit on SAP HANA. Maybe you are now asking for this two green boxes. See Ports and Connections in the SAP HANA documentation to learn about the list 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). There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*. 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 my opinion, the described configuration is only needed below situations. If you've got a moment, please tell us what we did right so we can do more of it. Many newer Amazon EC2 instance types such as the X1 use an optimized configuration stack and Maintain, reccomend and install SAP software for our client, including SAP Netweaver, ECC,R/3, APO and BW. communication, and, if applicable, SAP HSR network traffic. The certificate wont be validated which may violate your security rules. resumption after start or recovery after failure. Chat Offline. Updates parameters that are relevant for the HA/DR provider hook. You use this service to create the extended store and extended tables. Disables system replication capabilities on source site. SAP Data Intelligence (prev. Therefore, I would highly recommend to stick with the default value .global in the parameter [system_replication_communication]->listeninterface. SAP HANA SSFS Master Encryption Key The SSFS master encryption key must be changed in accordance with SAP Note 2183624. 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. Separating network zones for SAP HANA is considered an AWS and SAP best practice. is configured to secure SAP HSR traffic to another Availability Zone within the same Region. Only one dynamic tiering license is allowed per SAP HANA system. Privacy | Removes system replication configuration. 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. path for the system replication. Scale-out and System Replication(2 tiers), 4. well as for SAP HSR, Storage zone to persist SAP HANA data in the storage infrastructure for Enables a site to serve as a system replication source site. Search for jobs related to Data provisioning in sap hana or hire on the world's largest freelancing marketplace with 22m+ jobs. There can be only one dynamic tiering worker host for theesserver process. Have you already secured all communication in your HANA environment? Trademark. For details how this is working, read this blog. Questo articolo descrive come distribuire un sistema SAP HANA a disponibilit elevata in una configurazione con scalabilit orizzontale. Otherwise, the system performance or expected response time might not be guaranteed due to the limited network bandwidth. Network for internal SAP HANA communication between hosts at each site: 192.168.1. Darryl Griffiths Blog from 2014 SAP HANA SSL Security Essential System replication cannot be used in SAP HANA systems in which dynamic tiering is enabled. redirection. Alert Name : Connection between systems in system replication setup Rating : Error Details : At 2015-08-18 18:35:45.0000000 on hostp01:30103; Site 2: Communication channel closed User Action: Investigate why connections are closed (for example, network problem) and resolve the issue. documentation. Single node and System Replication(3 tiers)", for example, is that right? There are some documentations available by SAP, but some of them are outdated or not matching the customer environments/needs or not all-embracing. In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. The required ports must be available. The last step is the activation of the System Monitoring. 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. Your application automatically determines which tier to save data to: the SAP HANA in-memory store (the hot store), or extended storage (the warm store). with Tenant Databases. Another thing is the maintainability of the certificates. 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. Stopped the Replication to TIER2 and TIER3 and removed them from the system replication configuration Find SAP product documentation, Learning Journeys, and more. It's free to sign up and bid on jobs. implies that if there is a standby host on the primary system it network interface, see the AWS # 2020/4/15 Inserted Vitaliys blog link + XSA diagnose details Use Secure Shell (SSH) to connect to your EC2 instance at the OS level. global.ini -> [communication] -> listeninterface : .global or .internal Wonderful information in a couple of blogs!! Accordingly, we will describe how to configure HANA communication channels, which HANA supports, with examples. 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 extended store can reduce the size of your in-memory database. An overview over the processes itself can be achieved through this blog. It's a hidden feature which should be more visible for customers. Understood More Information Once the esserver service is assigned to a tenant database, the database, not SYSTEMDB, owns the service. 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. It must have the same software version or higher. of the same security group that controls inbound and outbound network traffic for the client Dynamic tiering enhances SAP HANA with large volume, warm data management capability. Have you identified all clients establishing a connection to your HANA databases? Perform SAP HANA You add rules to each security group that allow traffic to or from its associated Dynamic tiering is embedded within SAP HANA operational processes, such as standby setup, backup and recovery, and system replication. To learn more about this step, see Configuring Hostname Resolution for SAP HANA System Replication in the SAP It To set it up is one task, to maintain and operate it another.
