The certificate wont be validated which may violate your security rules. To learn more about this step, see Unregisters a secondary tier from system replication. Extended tables behave like all other SAP HANA tables, but their data resides in the disk-based extended store. We're sorry we let you down. SAP HANA 1.0, platform edition Keywords. For sure authorizations are also an important part but not in the context of this blog and far away from my expertise. Public communication channel configurations, 2. global.ini -> [communication] -> listeninterface : .global or .internal By default, this enables security and forces all resources to use ssl. (1) site1 is broken and needs repair; Both SAP HANA and dynamic tiering hosts, including standby hosts, use storage APIs to access the devices. 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. The additional process hdbesserver can be seen which confirms that Dynamic-Tiering worker has been successfully installed. Data Lifecycle Manager optimizes the memory footprint of data in SAP HANA tables by relocating data to Dynamic Tiering or HADOOP. Many newer Amazon EC2 instance types such as the X1 use an optimized configuration stack and Scale out of dynamic tiering is not available. # 2021/04/26 added PIN/passphrase option for sapgenpse seclogin Primary Host: Enable system replication. If you do this you configure every communication on those virtual names including the certificates! After the dynamic tiering component has been installed on HANA system, start with addition of worker DT host, by running hdblcm from worker DT node. Connection to On-Premise SAP ECC and S/4HANA. if no mappings specified(Default), the default network route is used for system replication communication. Recently we started receiving the alerts from our monitoring tool: Updated the listeninterface and internal_hostname_resolution parameters for the respective TIER as they are unique for every landscape Please note that SAP HANA Dynamic Tiering ("DT") is in maintenance only mode and is not recommended for new implementations. Communication Channel Security; Firewall Settings; . The change data for the parameters ssfs_masterkey_changed and ssfs_masterkey_systempki_changed archived in the view SYS.M_HOST_INFORMATION is changed. IMPORTANT : the parameters in the global.ini must be set prior to registering the secondary system which means that you need to un-register and re-register if you want to change the configurations. must be backed up. You can modify the rules for a security group at any time. different logical networks by specifying multiple private IP addresses for your instances. 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. ###########. We know for step(4), there could be one more takeover, and then site1 will become new primary, but since site1 and site2 has the same capacity, it's not necessary to introduce one more short downtime for production, right? In particolare, la configurazione usa la replica di sistema HANA (HSR) e Pacemaker in macchine virtuali Linux (VM) di Azure Red Hat Enterprise. Thanks for letting us know we're doing a good job! 2. # Edit * ww -- wwan, Ethernet cards will always start withen, but they might be followed by a, its key to remember the hex conversion of network cards, https://major.io/2015/08/21/understanding-systemds-predictable-network-device-names/. So we followed the below steps: Disables the preload of column table main parts. Create new network interfaces from the AWS Management Console or through the AWS CLI. thank you for this very valuable blog series! before a commit takes place on the local primary system. It is also possible to create one certificate per tenant. Configure SAP HANA hostname resolution to let SAP HANA communicate over the when site2(secondary) is not working any longer. The required ports must be available. You use this service to create the extended store and extended tables. Prerequisites You comply all prerequisites for SAP HANA system replication. The extended store can reduce the size of your in-memory database. Single node and System Replication(2 tiers), 2. external(public) network: Channels used for external access to SAP HANA functionality by end-user clients, administration clients, application servers, and for data provisioning via SQL or HTTP, internal network: Channels used for SAP HANA internal communication within the database or, in a distributed scenario, for communication between hosts. 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. that the new network interfaces are created in the subnet where your SAP HANA instance * sl -- serial line IP (slip) For more information about how to create a new database, ensure the following: To allow uninterrupted client communication with the SAP HANA
User Action: Investigate why connections are closed (for example, network problem) and resolve the issue. Contact us. own security group (not shown) to secure client traffic from inter-node communication. In my opinion, the described configuration is only needed below situations. Since NSE is a capability of the core HANA server, using NSE eliminates the limitations of DT that you highlighted above. # Edit 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. For each server you can add an own IP label to be flexible. Now you have to go to the HANA Cockpit Manager to change the registered resource to use SSL. Which communication channels can be secured? Figure 11: Network interfaces and security groups. 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. When you launch an instance, you associate one or more security groups with the Any changes made manually or by
Multiple interfaces => one or multiple labels (n:m). The BACKINT interface is available with SAP HANA dynamic tiering. is deployed. Post this, Installation of Dynamic Tiering License need to done via COCKPIT. extract the latest SAP Adaptive Extensions into this share. Another thing is the maintainability of the certificates. Maintain, reccomend and install SAP software for our client, including SAP Netweaver, ECC,R/3, APO and BW. 2478769 Obtaining certificates with subject Alternative Name (SAN) within STRUST Below query returns the internal hostname which we will use for mapping rule. Surprisingly the TIER3 system replication status did not show up on the Replication monitor in HANA studio A service in this context means if you have multiple services like multiple tenants on one server running. It's free to sign up and bid on jobs. 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. 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. HANA database explorer) with all connected HANA resources! configure security groups, see the AWS documentation. This note well describes the sequence of (un)registering/(re)registering when operating replication and upgrade. redirection. All mandatory configurations are also written in the picture and should be included in global.ini. Every label should have its own IP. exactly the type of article I was looking for. For those who are not familiar with JDBC/ODBC/SQLDBC connections a short excursion: This was the first part as preparation for the next part the practical one. Pre-requisites. Terms of use |
How to Configure SSL in SAP HANA 2.0 For details, you could have reference on the guide "How to perform How To Perform System Replication for SAP HANA". An optional add-on to the SAP HANA database for managing less frequently accessed warm data.

System Monitoring of SAP HANA with System Replication. labels) and the suitable routing for a stateful connection for your firewall rules and network segmentation. 2211663 . Assignment of esserver is done by below sql script: ALTER DATABASE ADD esserver [ AT [ LOCATION] [: ] ]. 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 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 SAP HANA and dynamic tiering each support NFS and SAN storage using storage connector APIs. It must have the same SAP system ID (SID) and instance
These are called EBS-optimized SAP HANA communicate over the internal network. The primary hosts listen on the dedicated ports of the separate network only, and incoming requests on the public interfaces are rejected. For this it may be wise to add an IP label, which means an own DNS record with name and IP, for each service. 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).

We are not talking about self-signed certificates. Credentials: Have access to the SYSTEM user of SystemDB and " <SID>adm " for a SSH session on the HANA hosts. * en -- ethernet Network for internal SAP HANA communication between hosts at each site: 192.168.1. First time, I Know that the mapping of hostname to IP can be different on each host in system replication relationship. HI DongKyun Kim, thanks for explanation . 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). United States. The latest release version of DT is SAP HANA 2.0 SP05. An additional license is not required. This is normally the public network. Certificate Management in SAP HANA This section describes operations that are available for SAP HANA instances. 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. Thanks DongKyun for sharing this through this nice post. 2487639 HANA Basic How-To Series HANA and SSL MASTER KBA Contact us. Privacy |
Please use part one for the knowledge basics. At the time of the parameters change in Production both TIER2 and TIER3 systems were stopped and removed from Replication setup need to specify all hosts of own site as well as neighboring sites. 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). Be careful with setting these parameters! All tenant databases running dynamic tiering share the single dynamic tiering license. 2487731 HANA Basic How-To Series HANA and SSL CSR, SIGN, IMPLEMENT (pse container ) for ODBC/JDBC connections. To pass the connection parameters to the DBSL, use the following profile parameter: dbs/hdb/connect_property = param1, param2, ., paramN, https://help.sap.com/viewer/b3ee5778bc2e4a089d3299b82ec762a7/2.0.04/en-US/0ae2b75266df44499d8fed8035e024ad.html. But keep in mind that jdbc_ssl parameter has no effect for Node.js applications! Refresh the page and To Be Configured would change to Properly Configured. So, the easiest way is to use the XSA set-certificate command: Afterwards check your system with the diagnose function. (details see part I). Introduction. # 2020/4/15 Inserted Vitaliys blog link + XSA diagnose details a distributed system. Here we talk about the client within the HANA client executable. Introduction. (4) site1 is repaired and joined the replication as secondary(sync to site2, site3 need unregistered from site2 and re-registered to site1). Its purpose is to extend SAP HANA memory with a disk-centric columnar store (as opposed to the SAP HANA in-memory store). Step 1 . Dynamic tiering is embedded within SAP HANA operational processes, such as standby setup, backup and recovery, and system replication. mapping rule : system_replication_internal_ip_address=hostname, As you recognized, .internal setting is a subset of .global and .global is a default and .global supports both 2-tiers and 3-tiers. 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. security group you created in step 1. There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*. Unregisters a system replication site on a primary system. You can also encrypt the communication for HSR (HANA System replication). So site1 & site3 won't meet except the case that I described. When you use SAP HANA to place hot data in SAP HANA in-memory tables, and warm data in extended tables, highest value data remains in memory, and cooler less-valuable data is saved to the extended store. For more information, see SAP HANA Database Backup and Recovery. In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. global.ini -> [communication] -> listeninterface : .global or .internal A shared file system (for example, /HANA/shared) is required for installation. System replication cannot be used in SAP HANA systems in which dynamic tiering is enabled. Using HANA studio. Create virtual host names and map them to the IP addresses associated with client, Since quite a while SAP recommends using virtual hostnames. For details how this is working, read this blog. 4. In HANA studio this process corresponds to esserver service. 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. 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 . 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. global.ini -> [internal_hostname_resolution] : ALTER SYSTEM ALTER CONFIGURATION ( global.ini, SYSTEM ) SET( customizable_functionalities, dynamic_tiering ) = true. You may choose to manage your own preferences. Internal communication is configured too openly 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. The customizable_functionalities property is defined in the SYSTEMDB globlal.ini file at the system level. SAP HANA Network Requirements Contact Us Contact us Contact us Home This site uses cookies and related technologies, as described in our privacy statement, for purposes that may include site operation, analytics, enhanced user experience, or advertising. And you need to change the parameter [communication]->listeninterface to .internal and add internal network entries as followings. Usually, tertiary site is located geographically far away from secondary site. Data Lifecycle Manager is a generic database-driven tool that enables you to model aging rules on SAP HANA tables to relocate aged or less frequently used data from SAP HANA tables in native SAP HANA applications. Do you have similar detailed blog for for Scale up with Redhat cluster. 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. It This is mentioned as a little note in SAP note 2300943 section 4. +1-800-872-1727. # 2021/03/18 Inserted XSA high security Kudos out to Patrick Heynen This will speed up your login instead of using the openssl variant which you discribed.
