Any changes made manually or by # Inserted new parameters from 2300943 resumption after start or recovery after failure. 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. 4. (more details in 8.) 2211663 . Wonderful information in a couple of blogs!! 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. Due the complexity of this topic the first part will once more the theoretical one and the second one will be more praxis oriented with the commands on the servers. Internal Network Configurations in System Replication : There are also configurations you can consider changing for system replications. RFC Module. These are called EBS-optimized 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). Now you have to go to the HANA Cockpit Manager to change the registered resource to use SSL. For each server you can add an own IP label to be flexible. network. instances. Terms of use | Privacy | So we followed the below steps: You add rules to each security group that allow traffic to or from its associated Trademark. For more information about how to create a new You have assigned the roles and groups required. Step 2. Have you identified all clients establishing a connection to your HANA databases? Maintain, reccomend and install SAP software for our client, including SAP Netweaver, ECC,R/3, APO and BW. This is normally the public network. This section describes operations that are available for SAP HANA instances. Single node and System Replication(3 tiers), 3. In general, there is no needs to add site3 information in site1, vice versa. Extracting the table STXL. Stopped the Replication to TIER2 and TIER3 and removed them from the system replication configuration We are not talking about self-signed certificates. no internal interface found, listeninterface, .internal , KBA , HAN-DB , SAP HANA Database , Problem . global.ini -> [system_replication_hostname_resolution] : 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. 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. # Edit Once the above task is performed the services running on DT worker host will appear in Landscape tab in hana studio. If you plan to use storage connector APIs, you must configure the multipath.conf and global.ini files before installation. 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. The change data for the parameters ssfs_masterkey_changed and ssfs_masterkey_systempki_changed archived in the view SYS.M_HOST_INFORMATION is changed. the global.ini file is set to normal for both systems. Copyright | There is already a blog about this configuration: https://blogs.sap.com/2014/01/17/configure-abap-to-hana-ssl-connection/ Step 1 . You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering. 3. number. If you answer one of the questions negative you should wait for the second part of this series , ########### For more information about how to attach a network interface to an EC2 * In the first example, the [system_replication_communication]listeninterface parameter has been set to .global and only the hosts of the neighboring replicating site are specified. 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!

The delta backup mechanism is not available with SAP HANA dynamic tiering. Data Lifecycle Manager optimizes the memory footprint of data in SAP HANA tables by relocating data to Dynamic Tiering or HADOOP. documentation. Maybe you are now asking for this two green boxes. 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. Darryl Griffiths Blog from 2014 SAP HANA SSL Security Essential You may choose to manage your own preferences. Recently we started receiving the alerts from our monitoring tool: SAP HANA and dynamic tiering each support NFS and SAN storage using storage connector APIs. System replication between two systems on Dynamic tiering adds smart, disk-based extended storage to your SAP HANA database. You can use the SQL script collection from note 1969700 to do this. You can use the same procedure for every other XSA installation. 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. The required ports must be available. first enable system replication on the primary system and then register the secondary Check all connecting interfaces for it. System Monitoring of SAP HANA with System Replication. For instance, you have 10.0.1. redirection. Separating network zones for SAP HANA is considered an AWS and SAP best practice.

Once the esserver service is assigned to a tenant database, the database, not SYSTEMDB, owns the service. All tenant databases running dynamic tiering share the single dynamic tiering license. It is also possible to create one certificate per tenant. Be careful with setting these parameters! On AS ABAP server this is controlled by is/local_addr parameter. network interface, see the AWS * wl -- wlan Binds the processes to this address only and to all local host interfaces. In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. Before we get started, let me define the term of network used in HANA. For details how this is working, read this blog. If there are multiple dynamic tiering hosts available and you do not specify a host or port, the SAP HANA system randomly selects from the available hosts. By default, on every installation the system gets a systempki (self-signed) until you import an own certificate. 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 To change the TLS version and the ciphers for the XSA you have to edit the xscontroller.ini. 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. 2386973 - Near Zero DowntimeUpgradesforHANADatabase 3-tierSystemReplication. Operators Detail, SAP Data Intelligence. As you create each new network interface, associate it with the appropriate Overview. (Storage API is required only for auto failover mechanism). 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. Click more to access the full version on SAP for Me (Login required). Multiple interfaces => one or multiple labels (n:m). Provisioning fails if the isolation level is high. Instance-specific metrics are basically metrics that can be specified "by . resolution is working by creating entries in all applicable host files or in the Domain Surprisingly the TIER3 system replication status did not show up on the Replication monitor in HANA studio It You can modify the rules for a security group at any time. There are some documentations available by SAP, but some of them are outdated or not matching the customer environments/needs or not all-embracing. More recently, we implemented a full-blown HANA in-memory platform . 2300943 Enabling SSL encryption for database connections for SAP HANA extended application services, advanced model, 2487639 HANA Basic How-To Series HANA and SSL MASTER KBA. connection recovery after disaster recovery with network-based IP 1761693 Additional CONNECT options for SAP HANA Scale-out and System Replication(3 tiers). Make sure SAP HANA dynamic tiering adds the SAP HANA dynamic tiering service (esserver) to your SAP HANA system. Applications, including utility programs, SAP applications, third-party applications and customized applications, must use an SAP HANA interface to access SAP HANA. HANA database explorer) with all connected HANA resources! 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). United States. received on the loaded tables. You may choose to manage your own preferences. /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. When set, a diamond appears in the database column. Usually system replication is used to support high availability and disaster recovery. Both SAP HANA and dynamic tiering hosts have their own dedicated storage. In HANA studio this process corresponds to esserver service. It must have a different host name, or host names in the case of SQL on one system must be manually duplicated on the other For more information about how to create and ENI-3 The instance number+1 must be free on both Find SAP product documentation, Learning Journeys, and more. So, the easiest way is to use the XSA set-certificate command: Afterwards check your system with the diagnose function. 2685661 - Licensing Required for HANA System Replication. installed. You can configure additional network interfaces and security groups to further isolate Linux' predictable network device names aka default network was "eth0" is now still predictably used as "enp1s0" with different rule set. -ssltrustcert have to be added to the call. savepoint (therefore only useful for test installations without backup and Above configurations are only required when you have internal networks. Are you already prepared for changing the server due to hardware change / OS upgrade with a virtual hostname concept? Here we talk about the client within the HANA client executable. If set on the primary system, the loaded table information is mapping rule : internal_ip_address=hostname. # 2020/4/15 Inserted Vitaliys blog link + XSA diagnose details SAP Host Agent must be able to write to the operations.d After a validation on the non prod systems the change was made on our Production landscape that is using the HANA System Replication (HSR) properties files (*.ini files). Comprehensive and complete, thanks a lot. # 2021/09/09 updated parameter info: is/local_addr thx @ Matthias Sander for the hint 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.
