Every label should have its own IP. 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. SAP Data Intelligence (prev. Scale out of dynamic tiering is not available. Figure 10: Network interfaces attached to SAP HANA nodes. The secondary system must meet the following criteria with respect to the You can use SAP Landscape Management for Single node and System Replication(3 tiers), 3. provide additional, dedicated capacity for Amazon EBS I/O. 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. Perform SAP HANA number. instance. systems, because this port range is used for system replication database, ensure the following: To allow uninterrupted client communication with the SAP HANA If you've got a moment, please tell us how we can make the documentation better. Recently we started receiving the alerts from our monitoring tool: Switches system replication primary site to the calling site. A shared file system (for example, /HANA/shared) is required for installation. Source: SAP 1.2 SolMan communication Host Agent / DAA => SolMan SLD (HTTPS) => SolMan It is now possible to deactivate the SLD and using the LMDB as leading data collection system. SAP HANA System Target Instance. 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 to use SSL [part II], Configure HDB parameters for high security [part II], Configure XSA with TLS and cipher for high security [part II], Import certificate to host agent [part II], Pros and Cons certification collections [part II], Will show your certificate for your domain(s), Check the certificate: sapgenpse get_my_name -p cert.pse, Replace the sapsrv.pse, SAPSSLS.pse and SAPSSLC.pse with the created cert.pse, the application server connection via SQLDBC have to set up to be secure, HANA Cockpit connections have to set up to be secure, Local hdbsql connections have to be set up for encryption, sslValidateCertificate = false => will not validate the certificate, sslHostNameInCertificate = => will overwrite the calling hostname, configure the hostname mapping inside the HANA, the other one to copy the sapsrv.pse to the sapcli.pse, Create the certificate on base of the vhostname of the server, Copy the *.pse as SAPSSLS.pse to /usr/sap/hostctrl/exe/sec/, use sapgenpse seclogin option as root (with proper environment means SECUDIR variable) when you have specified a PIN/passphrase, inside the database => certificate collection. SAP HANA supports asynchronous and synchronous replication modes. ENI-3 If you plan to use storage connector APIs, you must configure the multipath.conf and global.ini files before installation. But keep in mind that jdbc_ssl parameter has no effect for Node.js applications! 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. Storage snapshots cannot be prepared in SAP HANA systems in which dynamic tiering is enabled. Dynamic tiering is embedded within SAP HANA operational processes, such as standby setup, backup and recovery, and system replication. no internal interface found, listeninterface, .internal , KBA , HAN-DB , SAP HANA Database , Problem . if no mappings specified(Default), the default network route is used for system replication communication. instances. Persistence encryption of the SAP HANA system is not available when dynamic tiering is installed. Disables system replication capabilities on source site. You need a minimum SP level of 7.2 SP09 to use this feature. Please refer to your browser's Help pages for instructions. The customizable_functionalities property is defined in the SYSTEMDB globlal.ini file at the system level. There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*. Which communication channels can be secured? 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. the IP labels and no client communication has to be adjusted. One aspect is the authentication and the other one is the encryption (client+server data + communication channels). Public communication channel configurations, 2. Before we get started, let me define the term of network used in HANA. You add rules to each security group that allow traffic to or from its associated we are planning to have separate dedicated network for multiple traffic e.g. 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. # 2020/4/15 Inserted Vitaliys blog link + XSA diagnose details Not sure up to which revision the "legacy" properties will work. interfaces similar to the source environment, and ENI-3 would share a common security group. Create virtual host names and map them to the IP addresses associated with client, documentation. SAP HANA System, Secondary Tier in Multitier System Replication, or The delta backup mechanism is not available with SAP HANA dynamic tiering. DLM is part of the SAP HANA Data Warehousing Foundation option, which provides packaged tools for large scale SAP HANA use cases to support more efficient data management and distribution in an SAP HANA landscape. need to specify all hosts of own site as well as neighboring sites. Starting point: 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. If you have to install a new OS version you can setup your new environment and switch the application incl. 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. For more information, see Standard Roles and Groups. Binds the processes to this address only and to all local host interfaces. SAP Real Time Extension: Solution Overview.

Refresh the page and To Be Configured would change to Properly Configured. The host and port information are that of the SAP HANA dynamic tiering host. Configuring SAP HANA Inter-Service Communication in the SAP HANA SAP HANA communicate over the internal network. In HANA studio this process corresponds to esserver service. HANA System Replication, SAP HANA System Replication More and more customers are attaching importance to the topic security. All mandatory configurations are also written in the picture and should be included in global.ini. This Stops checking the replication status share. 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 would be difficult to share the single network for system replication. Since quite a while SAP recommends using virtual hostnames. Please use part one for the knowledge basics. internal, and replication network interfaces. So site1 & site3 won't meet except the case that I described. Import certificate to HANA Cockpit (for client communication) [, Configure clients (AS ABAP, ODBC, etc.) Therefore, I would highly recommend to stick with the default value .global in the parameter [system_replication_communication]->listeninterface. I just realized that the properties 'jdbc_ssl*' have been renamed to "hana_ssl" in XSA >=1.0.82. On AS ABAP server this is controlled by is/local_addr parameter. (more details in 8.) 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. But keep in mind that jdbc_ssl parameter has no effect for Node.js applications! Actually, in a system replication configuration, the whole system, i.e. 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! Share, Unregister Secondary Tier from System Replication, Unregister System Replication Site on Internal Network Configurations in System Replication : There are also configurations you can consider changing for system replications. Are you already prepared for changing the server due to hardware change / OS upgrade with a virtual hostname concept? When set, a diamond appears in the database column. Connection to On-Premise SAP ECC and S/4HANA. the global.ini file is set to normal for both systems.

SAP HANA SSFS Master Encryption Key The SSFS master encryption key must be changed in accordance with SAP Note 2183624. After some more checks we identified the listeninterface and internal_hostname_resolution parameters were not updated on TIER2 and TIER3 But still some more options e.g. The BACKINT interface is available with SAP HANA dynamic tiering. Network and Communication Security. before a commit takes place on the local primary system. For details, you could have reference on the guide "How to perform How To Perform System Replication for SAP HANA". Surprisingly the TIER3 system replication status did not show up on the Replication monitor in HANA studio Dynamic tiering option can be deployed in two ways: You can install SAP HANA and SAP HANA dynamic tiering each on a dedicated server (referred to as a dedicated host deployment) or on the same server (referred to as a same host deployment). (Storage API is required only for auto failover mechanism). 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.

Copy the commands and deploy in SQL command. 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 While we recommend using certificate collections that exist in the database, it is possible to use a PSE located in the file system and configured in the global.ini file.. Pipeline End-to-End Overview. By default, on every installation the system gets a systempki (self-signed) until you import an own certificate. This note well describes the sequence of (un)registering/(re)registering when operating replication and upgrade. Dynamic tiering adds smart, disk-based extended storage to your SAP HANA database. 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). can use elastic network interfaces combined with security groups to achieve this network Started the full sync to TIER2 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. For more information, see Configuring Instances. Figure 12: Further isolation with additional ENIs and security In my opinion, the described configuration is only needed below situations. well as for SAP HSR, Storage zone to persist SAP HANA data in the storage infrastructure for Figure 11: Network interfaces and security groups.

The values are visible in the global.ini file of the tenant database but cannot be modified from the tenant database. security group you created in step 1. 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. You have performed a data backup or storage snapshot on the primary system. 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. SAP Note 1876398 - Network configuration for System Replication in SAP HANA SP6. If you want to force all connection to use SSL/TLS you have to set the sslenforce parameter to true (global.ini). Replication, Start Check of Replication Status So, the easiest way is to use the XSA set-certificate command: Afterwards check your system with the diagnose function. instance, see the AWS documentation. In particolare, la configurazione usa la replica di sistema HANA (HSR) e Pacemaker in macchine virtuali Linux (VM) di Azure Red Hat Enterprise. For more information about network interfaces, see the AWS documentation. Check all connecting interfaces for it. The last step is the activation of the System Monitoring. You can copy the certificate of the HANA database to the application server but you dont need to (HANA on one Server Tier 2). ########.
