* Dedicated network for system replication: 10.5.1. You can configure additional network interfaces and security groups to further isolate Refresh the page and To Be Configured would change to Properly Configured. 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! global.ini -> [communication] -> listeninterface : .global or .internal global.ini -> [system_replication_communication] -> listeninterface : .global or .internal You add rules to each security group that allow traffic to or from its associated Perform backup on primary. Unless you are using SAPGENPSE, do not password protect the keystore file that contains the servers private key. So I think each host, we need maintain two entries for "2. (Addition of DT worker host can be performed later). 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. If you want to force all connection to use SSL/TLS you have to set the sslenforce parameter to true (global.ini). The parameter listeninterface=.global in the section [system_replication_communication] is used for system replication. 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). This
Dynamic tiering is embedded within SAP HANA operational processes, such as standby setup, backup and recovery, and system replication. steps described in the appendix to configure need not be available on the secondary system. before a commit takes place on the local primary system. mapping rule : system_replication_internal_ip_address=hostname, 1. Find SAP product documentation, Learning Journeys, and more. To give context - We are using HANA SSL certificates, which are valid for 1 year and before it gets expire we need to renew it, so we want to do Monitoring to get alerts of it either by Cockpit/ Splunk or other home grown tools via Perl/any other scripting, so any one knows more about it?? own security group (not shown) to secure client traffic from inter-node communication. When set, a diamond appears in the database column. This is necessary to start creating log backups. For more information, see Standard Permissions. Before we get started, let me define the term of network used in HANA. (3) site3 is still registered to the site2 (as it's not impacted, async only as remote DR); of the same security group that controls inbound and outbound network traffic for the client 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. Network for internal SAP HANA communication between hosts at each site: 192.168.1. replication network for SAP HSR. number. Thanks for the further explanation. mapping rule : internal_ip_address=hostname. * Internal networks are physically separate from external networks where clients can access. Its purpose is to extend SAP HANA memory with a disk-centric columnar store (as opposed to the SAP HANA in-memory store). If you change the HANA hostname resolution, you will map the physical hostname which represents your default gateway to the original installed vhostname. For more information, see Configuring Instances. Each tenant requires a dedicated dynamic tiering host. You use this service to create the extended store and extended tables. Data Hub) Connection. You can use the SQL script collection from note 1969700 to do this. Single node and System Replication(3 tiers)", for example, is that right? For more information about how to attach a network interface to an EC2 Wonderful information in a couple of blogs!! 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. For more information, see: network interfaces you will be creating. documentation. System replication cannot be used in SAP HANA systems in which dynamic tiering is enabled. Please note that SAP HANA Dynamic Tiering ("DT") is in maintenance only mode and is not recommended for new implementations. The extended store can reduce the size of your in-memory database. 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. Not sure up to which revision the "legacy" properties will work. 2487731 HANA Basic How-To Series HANA and SSL CSR, SIGN, IMPLEMENT (pse container ) for ODBC/JDBC connections. Unregisters a system replication site on a primary system. 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. Follow the If you've got a moment, please tell us how we can make the documentation better. Activated log backup is a prerequisite to get a common sync point for log
An overview over the processes itself can be achieved through this blog. (more details in 8.). On AS ABAP server this is controlled by is/local_addr parameter. documentation. least SAP HANA1.0 Revision 81 or higher. Disables system replication capabilities on source site. Connection to On-Premise SAP ECC and S/4HANA. Privacy |
By default, on every installation the system gets a systempki (self-signed) until you import an own certificate. Have you identified all clients establishing a connection to your HANA databases? Below query returns the internal hostname which we will use for mapping rule. Above configurations are only required when you have internal networks. Contact us. Thanks for letting us know this page needs work. You set up system replication between identical SAP HANA systems. Contact us. The new rules are replication. 1. System replication between two systems on
So we followed the below steps: All mandatory configurations are also written in the picture and should be included in global.ini. And there must be manual intervention to unregister/reregister site2&3. Configuring SAP HANA Inter-Service Communication in the SAP HANA SAP User Role CELONIS_EXTRACTION in Detail. SQL on one system must be manually duplicated on the other
For each server you can add an own IP label to be flexible. Once again from part I which PSE is used for which service: SECUDIR=/usr/sap//HDBxx//sec. a distributed system. More recently, we implemented a full-blown HANA in-memory platform . If this is not possible, because it is a mounted NFS share,
A shared file system (for example, /HANA/shared) is required for installation. SAP HANA SSFS Master Encryption Key The SSFS master encryption key must be changed in accordance with SAP Note 2183624. In the following example, ENI-1 of each instance shown is a member As promised here is the second part (practical one) of the series about the secure network communication. The same instance number is used for
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. internal, and replication network interfaces. Certificate Management in SAP HANA SAP Note 1876398 - Network configuration for System Replication in SAP HANA SP6. Introduction. If set on
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 Only set this to true if you have configured all resources with SSL. Any changes made manually or by
HI DongKyun Kim, thanks for explanation . Here we talk about the client within the HANA client executable. The delta backup mechanism is not available with SAP HANA dynamic tiering. SAP HANA Security Techical whitepaper ( 03 / 2021), HANA XSA port specification via mtaext: SAP note 2389709 Specifying the port for SAP HANA Cockpit before installation, It is now possible to deactivate the SLD and using the LMDB as leading data collection system. 3. SAP HANA supports asynchronous and synchronous replication modes. 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 # Inserted new parameters from 2300943 This note well describes the sequence of (un)registering/(re)registering when operating replication and upgrade. Are you already prepared with multiple interfaces (incl. Disables the preload of column table main parts. SAP Real Time Extension: Solution Overview. As you may read between the lines Im not a fan of authorization concepts. Check all connecting interfaces for it. 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. 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. 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. system. operations or SAP HANA processes as required. 2487639 HANA Basic How-To Series HANA and SSL MASTER KBA System replication overview Replication modes Operation modes Replication Settings Here your should consider a standard automatism. 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. global.ini -> [system_replication_hostname_resolution] : Step 1. secondary. 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. Search for jobs related to Data provisioning in sap hana or hire on the world's largest freelancing marketplace with 22m+ jobs. System Monitoring of SAP HANA with System Replication. Only one dynamic tiering license is allowed per SAP HANA system. network interface in the remainder of this guide), you can create 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. Figure 10: Network interfaces attached to SAP HANA nodes. In HANA studio this process corresponds to esserver service. We are talk about signed certificates from a trusted root-CA. SAP HANA 1.0, platform edition Keywords. instances. Make sure 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. Stops checking the replication status share. (details see part I). It must have the same software version or higher. 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. (more details in 8.) 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. Dynamic tiering enhances SAP HANA with large volume, warm data management capability. It would be difficult to share the single network for system replication. network interface, see the AWS Both SAP HANA and dynamic tiering hosts, including standby hosts, use storage APIs to access the devices. Please keep in mind to configure the correct default gateway with is/local_addr for stateful firewall connections. 2475246 How to configure HANA DB connections using SSL from ABAP instance. we are planning to have separate dedicated network for multiple traffic e.g. (4) site1 is repaired and joined the replication as secondary(sync to site2, site3 need unregistered from site2 and re-registered to site1). communications. global.ini -> [internal_hostname_resolution] : SQLDBC is the basis for most interfaces; however, it is not used directly by applications. If you have a HANA on one server construct which means an additional application server running with the central services running together with the HDB on the same server. Or see our complete list of local country numbers. If you copy your certificate to sapcli.pse inside your SECUDIR you won't have to add it to the hdbsql command. Configure SAP HANA hostname resolution to let SAP HANA communicate over the You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering. After a validation on the non prod systems the change was made on our Production landscape that is using the HANA System Replication (HSR) HANA database explorer) with all connected HANA resources! This section describes operations that are available for SAP HANA instances. Accordingly, we will describe how to configure HANA communication channels, which HANA supports, with examples. SAP HANA System, Secondary Tier in Multitier System Replication, or
SAP is using mostly one certificate for all components (host agent, DAA, SystemDB, Tenant) which belongs to the physical hostname (systempki). Internal communication is configured too openly 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). Changed the parameter so that I could connect to HANA using HANA Studio. primary and secondary systems. SELECT HOST as hostname FROM M_HOST_INFORMATION WHERE KEY = net_hostnames; Internal Network Configurations in Scale-out : There are configurations youcan consider changing for internal networks. But keep in mind that jdbc_ssl parameter has no effect for Node.js applications! Ensure that host name-to-IP-address multiple physical network cards or virtual LANs (VLANs). recovery). communication, and, if applicable, SAP HSR network traffic. An elastic network interface is a virtual network interface that you can attach to an We are actually considering the following scenarios: # Edit All tenant databases running dynamic tiering share the single dynamic tiering license. 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. the IP labels and no client communication has to be adjusted. with Tenant Databases. Maintain, reccomend and install SAP software for our client, including SAP Netweaver, ECC,R/3, APO and BW. 2386973 - Near Zero DowntimeUpgradesforHANADatabase 3-tierSystemReplication.
