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.. SAP HANA Tenant Database . 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. Log mode Post this, Installation of Dynamic Tiering License need to done via COCKPIT. -Jens (follow me on Twitter for more geeky news @JensGleichmann), ######## SAP Note 1876398 - Network configuration for System Replication in SAP HANA SP6. 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. Each tenant requires a dedicated dynamic tiering host. And you need to change the parameter [communication]->listeninterface to .internal and add internal network entries as followings. Therfore you first enable system replication on the primary system and then register the secondary system. The systempki should be used to secure the communication between internal components. * sl -- serial line IP (slip) 2685661 - Licensing Required for HANA System Replication. 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. mapping rule : internal_ip_address=hostname. 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 network interface, see the AWS Log mode normal means that log segments are backed up. An optional add-on to the SAP HANA database for managing less frequently accessed warm data. To learn Figure 12: Further isolation with additional ENIs and security SAP HANA dynamic tiering is an integrated component of the SAP HANA database and cannot be operated independently from SAP HANA. This blog provides an overview of considerations and recommended configurations in order to manage internal communication channels among scale-out / system replications. Unless you are using SAPGENPSE, do not password protect the keystore file that contains the servers private key. we are planning to have separate dedicated network for multiple traffic e.g. Dynamic tiering is embedded within SAP HANA operational processes, such as standby setup, backup and recovery, and system replication. Wanting to use predictable network device names in a custom way is going, * Two character prefixes based on the type of interface: Search for jobs related to Data provisioning in sap hana or hire on the world's largest freelancing marketplace with 22m+ jobs. 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 Dynamic tiering enhances SAP HANA with large volume, warm data management capability. # 2020/04/14 Insert of links / blogs as starting point, links for part II You can copy the certificate of the HANA database to the application server but you dont need to (HANA on one Server Tier 2). 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). 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. RFC Module. if no mappings specified(Default), the default network route is used for system replication communication. Find SAP product documentation, Learning Journeys, and more. After some more checks we identified the listeninterface and internal_hostname_resolution parameters were not updated on TIER2 and TIER3 You can modify the rules for a security group at any time. 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). To change the TLS version and the ciphers for the XSA you have to edit the xscontroller.ini. This option requires an internal network address entry. of the same security group that controls inbound and outbound network traffic for the client 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). first enable system replication on the primary system and then register the secondary Thanks a lot for sharing this , it's a excellent blog . overwrite means log segments are freed by the operations or SAP HANA processes as required. global.ini -> [system_replication_communication] -> listeninterface : .global or .internal mapping rule : internal_ip_address=hostname. Starts checking the replication status share. thank you for this very valuable blog series! Create virtual host names and map them to the IP addresses associated with client, SAP HANA Native Storage Extension ("NSE") is the recommended approach to implementing data tiering within an SAP HANA system. Conversely, on the AWS Cloud, you network. Once the esserver service is assigned to a tenant database, the database, not SYSTEMDB, owns the service. Disables system replication capabilities on source site. 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). Unregisters a secondary tier from system replication. SAP HANA supports asynchronous and synchronous replication modes. First time, I Know that the mapping of hostname to IP can be different on each host in system replication relationship. For your information, I copy sap note If you have to install a new OS version you can setup your new environment and switch the application incl. (Addition of DT worker host can be performed later). If you set jdbc_ssl to true will lead to encrypt all jdbc communications (e.g. # 2021/04/06 Inserted possibility for multiple SAN in one request / certificate with sapgenpse provide additional, dedicated capacity for Amazon EBS I/O. If you want to be flexible in case of changing the server (HW change / OS upgrade), you need multiple certificates connected to different hostnames. Connection to On-Premise SAP ECC and S/4HANA. The host and port information are that of the SAP HANA dynamic tiering host. when site2(secondary) is not working any longer. 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. The bottom line is to make site3 always attached to site2 in any cases. 1. 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. system. Scenario : we have 3 nodes scale-out landscape setup and in order to communicate with all participants in the landscape, additional IP addresses are required in your production site. Secondary : Register secondary system. 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. * wl -- wlan Above configurations are only required when you have internal networks. The latest release version of DT is SAP HANA 2.0 SP05. HANA database explorer) with all connected HANA resources! So site1 & site3 won't meet except the case that I described. a distributed system. For more information about how to attach a network interface to an EC2 I just realized that the properties 'jdbc_ssl*' have been renamed to "hana_ssl" in XSA >=1.0.82. Please use part one for the knowledge basics. It must have the same system configuration in the system instance. Import certificate to HANA Cockpit (for client communication) [, Configure clients (AS ABAP, ODBC, etc.) We are not talking about self-signed certificates. You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering. Copyright | mapping rule : system_replication_internal_ip_address=hostname, 1. 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).

Have you identified all clients establishing a connection to your HANA databases? Stops checking the replication status share. These steps helped resolve the issue and the System Replication monitor was now reflecting all 3 TIERS Run hdblcm (with root) with the path of extracted software as parameter and install dynamic tiering component without addition of DT host. SAP HANA dynamic tiering adds the SAP HANA dynamic tiering service (esserver) to your SAP HANA system. In the step 5, it is possible to avoid exporting and converting the keys. 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. SAP Data Intelligence (prev. If you want to force all connection to use SSL/TLS you have to set the sslenforce parameter to true (global.ini). So I think each host, we need maintain two entries for "2. This For sure authorizations are also an important part but not in the context of this blog and far away from my expertise. To use the Amazon Web Services Documentation, Javascript must be enabled. ###########. Certificate Management in SAP HANA When set, a diamond appears in the database column. Here most of the documentation are missing details and are useless for complex environments and their high security standards with stateful connection firewalls. Network and Communication Security. * The hostname in below refers to internal hostname in Part1. Provisioning fails if the isolation level is high. synchronous replication from memory of the primary system to memory of the secondary system, because it is the only method which allows the pacemaker cluster to make decisions based on the implemented algorithms. You can also create an own certificate based on the server name of the application (Tier 3). 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. The cleanest way is the Golden middle option 2. Application, Replication, host management , backup, Heartbeat. Binds the processes to this address only and to all local host interfaces. Step 2. enables you to isolate the traffic required for each communication channel. Configure SAP HANA hostname resolution to let SAP HANA communicate over the groups. Following parameters is set after configuring internal network between hosts. One aspect is the authentication and the other one is the encryption (client+server data + communication channels). database, ensure the following: To allow uninterrupted client communication with the SAP HANA (1) site1 is broken and needs repair; 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. Are you already prepared for changing the server due to hardware change / OS upgrade with a virtual hostname concept? SAP HANA dynamic tiering is a native big data solution for SAP HANA. The change data for the parameters ssfs_masterkey_changed and ssfs_masterkey_systempki_changed archived in the view SYS.M_HOST_INFORMATION is changed.
