Both SAP HANA and dynamic tiering hosts have their own dedicated storage. Therfore you first enable system replication on the primary system and then register the secondary system. 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. 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. Any ideas? Usually system replication is used to support high availability and disaster recovery. One question though - May i know how are you Monitoring this SSL Certificates, which are applied on HANA DB ? network interface in the remainder of this guide), you can create 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. 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. Therfore you
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 global.ini -> [internal_hostname_resolution] : Activated log backup is a prerequisite to get a common sync point for log
It must have the same SAP system ID (SID) and instance
* wl -- wlan Only set this to true if you have configured all resources with SSL. 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. Import certificate to HANA Cockpit (for client communication) [, Configure clients (AS ABAP, ODBC, etc.) Here you can reuse your current automatism for updating them. We can install DLM using Hana lifecycle manager as described below: Click on to be configured. Single node and System Replication(3 tiers)", for example, is that right? For instance, you have 10.0.1. Changed the parameter so that I could connect to HANA using HANA Studio. Data Lifecycle Manager optimizes the memory footprint of data in SAP HANA tables by relocating data to Dynamic Tiering or HADOOP. SAP HANA components communicate over the following logical network zones: Client zone to communicate with different clients such as SQL clients, SAP For scale-out deployments, configure SAP HANA inter-service communication to let secondary. Figure 12: Further isolation with additional ENIs and security This note well describes the sequence of (un)registering/(re)registering when operating replication and upgrade. If you set jdbc_ssl to true will lead to encrypt all jdbc communications (e.g. first enable system replication on the primary system and then register the secondary

There is already a blog about this configuration: https://blogs.sap.com/2014/01/17/configure-abap-to-hana-ssl-connection/ The last step is the activation of the System Monitoring. * Dedicated network for system replication: 10.5.1. Otherwise, please ignore this section. Wilmington, Delaware. Following parameters is set after configuring internal network between hosts. 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. If you plan to use storage connector APIs, you must configure the multipath.conf and global.ini files before installation. Starting point: Which communication channels can be secured? the same host is not supported. Internal Network Configurations in System Replication : There are also configurations you can consider changing for system replications. Network for internal SAP HANA communication: 192.168.1. Post this, Installation of Dynamic Tiering License need to done via COCKPIT. Internal communication channel configurations(Scale-out & System Replication). 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! 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 These are called EBS-optimized You have installed SAP Adaptive Extensions. Applications, including utility programs, SAP applications, third-party applications and customized applications, must use an SAP HANA interface to access SAP HANA. 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. This optimization provides the best performance for your EBS volumes by SAP Host Agent must be able to write to the operations.d
different logical networks by specifying multiple private IP addresses for your instances. 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. I haven't seen it yet, but I will link it in this post.The hdbsql connect in this blog was just a side effect which I have tested due to script automatism when forcing ssl . (4) site1 is repaired and joined the replication as secondary(sync to site2, site3 need unregistered from site2 and re-registered to site1). 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. with Tenant Databases. The bottom line is to make site3 always attached to site2 in any cases. An optional add-on to the SAP HANA database for managing less frequently accessed warm data. At the time of the parameters change in Production both TIER2 and TIER3 systems were stopped and removed from Replication setup SAP HANA dynamic tiering is a native big data solution for SAP HANA. You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering. Chat Offline.

SAP User Role CELONIS_EXTRACTION in Detail. primary and secondary systems. You cant provision the same service to multiple tenants. Log mode normal means that log segments are backed up. The secondary system must meet the following criteria with respect to the
1. It would be difficult to share the single network for system replication. 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. Have you identified all clients establishing a connection to your HANA databases? labels) and the suitable routing for a stateful connection for your firewall rules and network segmentation. Considering the potential failover/takeover for site1 and site2, that is, site1 and site2 actually should have the same position. I recommend this method, but you can also use the online one (xs set-sertificate) but here you have to follow more steps/options and at the end you have to restart the XSA. You need at

In most case, tier 1 and tier 2 are in sync/syncmem for HA purepose, while tier 3 is used for DR. You have performed a data backup or storage snapshot on the primary system. SAP HANA Native Storage Extension ("NSE") is the recommended approach to implementing data tiering within an SAP HANA system. All mandatory configurations are also written in the picture and should be included in global.ini. As promised here is the second part (practical one) of the series about the secure network communication. Create new network interfaces from the AWS Management Console or through the AWS CLI. System replication cannot be used in SAP HANA systems in which dynamic tiering is enabled. Updates parameters that are relevant for the HA/DR provider hook. The required ports must be available. Multiple interfaces => one or multiple labels (n:m). 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.) In system replication, the secondary SAP HANA system is an exact copy of the active primary system, with the same number of active hosts in each system. A separate network is used for system replication communication. 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 Connection to On-Premise SAP ECC and S/4HANA. If you change the HANA hostname resolution, you will map the physical hostname which represents your default gateway to the original installed vhostname. 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. You comply all prerequisites for SAP HANA system
In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. Ensures that a log buffer is shipped to the secondary system
The cleanest way is the Golden middle option 2. Comprehensive and complete, thanks a lot. There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*. 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). Network and Communication Security. System Monitoring of SAP HANA with System Replication. From Solution Manager 7.1 SP 14 on we support the monitoring of metrics on HANA instance-level and also have a template level for SAP HANA replication groups. Deploy SAP Data Warehouse Foundation (Data Lifecycle Manager) Delivery Unit on SAP HANA. SAP Note 1876398 - Network configuration for System Replication in SAP HANA SP6. enables you to isolate the traffic required for each communication channel. (2) site2 take over the primary role; On AS ABAP server this is controlled by is/local_addr parameter. 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.
