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. Would be good to have any feedback from any customers that have come across this and it will be useful for any customers that are planning to make this change in their landscape, Alerting is not available for unauthorized users. Please provide your valuable feedback and please connect with me for any questions. * sl -- serial line IP (slip) overwrite means log segments are freed by the installed. 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. With MDC (or like SAP says now container/tenants) you always have a systemDB and a tenant. Failover nodes mount the storage as part of the failover process. (1) site1 is broken and needs repair; 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. If set on 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 redirection. This is mentioned as a little note in SAP note 2300943 section 4. 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). HANA System Replication, SAP HANA System Replication If you have to install a new OS version you can setup your new environment and switch the application incl. (check SAP note 2834711). systems, because this port range is used for system replication But the, SAP app server on same machine, tries to connect to mapped external hostname and if tails of course. Amazon EBS-optimized instances can also be used for further isolation for storage I/O. is deployed. the secondary system, this information is evaluated and the 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. The bottom line is to make site3 always attached to site2 in any cases. * Dedicated network for system replication: 10.5.1. System replication between two systems on This is the preferred method to secure the system as it's done automatically and the certificates are renewed when necessary. multiple physical network cards or virtual LANs (VLANs). Maybe you are now asking for this two green boxes. 1761693 Additional CONNECT options for SAP HANA Pre-requisites. documentation. For more information, see SAP Note 2475246 How to configure HANA DB connections using SSL from ABAP instance. Are you already prepared with multiple interfaces (incl. Comprehensive and complete, thanks a lot. shipping between the primary and secondary system. You can also create an own certificate based on the server name of the application (Tier 3). An elastic network interface is a virtual network interface that you can attach to an In particolare, la configurazione usa la replica di sistema HANA (HSR) e Pacemaker in macchine virtuali Linux (VM) di Azure Red Hat Enterprise. When complete, test that the virtual host names can be resolved from mapping rule : system_replication_internal_ip_address=hostname, 1. /hana/shared should be mounted on both the hosts namely HANA host and Dynamic Tiering host which will contain installation files of HANA and Dynamic Tiering service. 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. Both SAP HANA and dynamic tiering hosts have their own dedicated storage. For more information, see Assigning Virtual Host Names to Networks. (Addition of DT worker host can be performed later). ALTER SYSTEM ALTER CONFIGURATION ( global.ini, SYSTEM ) SET( customizable_functionalities, dynamic_tiering ) = true. Step 3. Keep the tenant isolation level low on any tenant running dynamic tiering. There can be only one dynamic tiering worker host for theesserver process. The additional process hdbesserver can be seen which confirms that Dynamic-Tiering worker has been successfully installed. * wl -- wlan SAP HANA System Target Instance. For more information, see SAP HANA Database Backup and Recovery. (more details in 8.) Pre-requisites. You need a minimum SP level of 7.2 SP09 to use this feature. You need at SAP HANA components communicate over the following logical network zones: Client zone to communicate with different clients such as SQL clients, SAP 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). Ensure that host name-to-IP-address own security group (not shown) to secure client traffic from inter-node communication. 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. number. communication, and, if applicable, SAP HSR network traffic. 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. A shared file system (for example, /HANA/shared) is required for installation. Surprisingly the TIER3 system replication status did not show up on the Replication monitor in HANA studio 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 minimizing contention between Amazon EBS I/O and other traffic from your instance. Network for internal SAP HANA communication between hosts at each site: 192.168.1. Step 1. If you want to force all connection to use SSL/TLS you have to set the sslenforce parameter to true (global.ini). You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering. Thanks DongKyun for sharing this through this nice post. System replication overview Replication modes Operation modes Replication Settings Global Network ENI-3 -ssltrustcert have to be added to the call. Any changes made manually or by 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. Once the above task is performed the services running on DT worker host will appear in Landscape tab in hana studio. Internal communication channel configurations(Scale-out & System Replication), Part2. This section describes operations that are available for SAP HANA instances. Copy the commands and deploy in SQL command. Wonderful information in a couple of blogs!!

If you've got a moment, please tell us what we did right so we can do more of it. 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. least SAP HANA1.0 Revision 81 or higher. 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. instances. You have installed and configured two identical, independently-operational. In the following example, ENI-1 of each instance shown is a member With an elastic network interface (referred to as We are not talking about self-signed certificates. Please refer to your browser's Help pages for instructions. To configure your logical network for SAP HANA, follow these steps: Create new security groups to allow for isolation of client, internal After a validation on the non prod systems the change was made on our Production landscape that is using the HANA System Replication (HSR) 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. thank you for this very valuable blog series! If this is not possible, because it is a mounted NFS share, # Inserted new parameters from 2300943 Changes the replication mode of a secondary site. You can use the SQL script collection from note 1969700 to do this. SAP HANA Network and Communication Security SAP Note 1876398 - Network configuration for System Replication in SAP HANA SP6. If you do this you configure every communication on those virtual names including the certificates! Linux' predictable network device names aka default network was "eth0" is now still predictably used as "enp1s0" with different rule set.

Please note that SAP HANA Dynamic Tiering ("DT") is in maintenance only mode and is not recommended for new implementations. To set it up is one task, to maintain and operate it another. Because site1 and site2 usually resides in the same data center but site3 is located very far in another data center. global.ini -> [communication] -> listeninterface : .global or .internal Introduction. As mentioned earlier, having internal networks are essential in production system in order to get the expected response time and optimize the system performance. all SAP HANA nodes and clients. SAP HANA Network and Communication Security, 2478769 Obtaining certificates with subject Alternative Name (SAN) within STRUST, 2487639 HANA Basic How-To Series HANA and SSL MASTER KBA, Darryl Griffiths Blog from 2014 SAP HANA SSL Security Essential, Certificate chain (multiple certificates in one file), cryptography toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) network protocols. 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. Using HANA studio. Using command line tool hdbnsutil: Primary : Attach the network interfaces you created to your EC2 instance where SAP HANA is Import certificate to HANA Cockpit (for client communication) [, Configure clients (AS ABAP, ODBC, etc.) For instance, you have 10.0.1. These steps helped resolve the issue and the System Replication monitor was now reflecting all 3 TIERS global.ini -> [system_replication_hostname_resolution] : 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. 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. Thanks a lot for sharing this , it's a excellent blog . Only one dynamic tiering license is allowed per SAP HANA system. It is also important to configure the appropriate network communication routing, because per default every traffic on a Linux server goes per default over the default gateway which is by default the first interface eth0 (we will need this know how later for the certificates). 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 host and port information are that of the SAP HANA dynamic tiering host. of the same security group that controls inbound and outbound network traffic for the client 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.
