But keep in mind that jdbc_ssl parameter has no effect for Node.js applications! For each server you can add an own IP label to be flexible. +1-800-872-1727. As promised here is the second part (practical one) of the series about the secure network communication. * wl -- wlan (4) site1 is repaired and joined the replication as secondary(sync to site2, site3 need unregistered from site2 and re-registered to site1). * as public network and 192.168.1. Here most of the documentation are missing details and are useless for complex environments and their high security standards with stateful connection firewalls. Do you have similar detailed blog for for Scale up with Redhat cluster. a distributed system. Pre-requisites. * Dedicated network for system replication: 10.5.1. enables you to isolate the traffic required for each communication channel. Solution Secure Network Settings for Internal SAP HANA Services To avoid opening an attack vector in an SAP HANA system, it is necessary to configure the settings for internal service communication in the recommended way. # Edit Linux' predictable network device names aka default network was "eth0" is now still predictably used as "enp1s0" with different rule set. After a validation on the non prod systems the change was made on our Production landscape that is using the HANA System Replication (HSR) secondary. Network for internal SAP HANA communication between hosts at each site: 192.168.1. Unregisters a secondary tier from system replication. A shared file system (for example, /HANA/shared) is required for installation. Perform SAP HANA
When complete, test that the virtual host names can be resolved from If you copy your certificate to sapcli.pse inside your SECUDIR you won't have to add it to the hdbsql command. * In the first example, the [system_replication_communication]listeninterface parameter has been set to .global and the neighboring hosts are specified. Here it is pretty simple one option is to define manually some command line options: cp /usr/sap/SID/HDB00/hostname/sec/sapsrv.pse /usr/sap/SID/HDB00/hostname/sec/sapcli.pse. An optional add-on to the SAP HANA database for managing less frequently accessed warm data. mapping rule : internal_ip_address=hostname. Thanks DongKyun for sharing this through this nice post. received on the loaded tables. Pre-requisites. Wilmington, Delaware. Global Network both the SAP HANA databases on the primary and the secondary site share the same license key, identified by the System Identifier (SID) and an automatically generated hardware key. resolution is working by creating entries in all applicable host files or in the Domain # Edit system, your high-availability solution has to support client connection

(Addition of DT worker host can be performed later). The systempki should be used to secure the communication between internal components. Contact us. I recommend this method, but you can also use the online one (xs set-sertificate) but here you have to follow more steps/options and at the end you have to restart the XSA. Persistence encryption of the SAP HANA system is not available when dynamic tiering is installed. SAP Note 1834153 . replication network for SAP HSR. 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. If set on
Before we get started, let me define the term of network used in HANA. Activated log backup is a prerequisite to get a common sync point for log
Operators Detail, SAP Data Intelligence. 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? Follow the Because site1 and site2 usually resides in the same data center but site3 is located very far in another data center. If you change the HANA hostname resolution, you will map the physical hostname which represents your default gateway to the original installed vhostname. must be backed up. 1761693 Additional CONNECT options for SAP HANA SAP is using mostly one certificate for all components (host agent, DAA, SystemDB, Tenant) which belongs to the physical hostname (systempki). These steps helped resolve the issue and the System Replication monitor was now reflecting all 3 TIERS On every installation of an SAP application you have to take care of this names. Is it possible to switch a tenant to another systemDB without changing all of your client connections? with Tenant Databases. global.ini: Set inside the section [communication] ssl from off to systempki. # 2021/04/06 Inserted possibility for multiple SAN in one request / certificate with sapgenpse global.ini -> [system_replication_hostname_resolution] : Understood More Information One question though - May i know how are you Monitoring this SSL Certificates, which are applied on HANA DB ? -Jens (follow me on Twitter for more geeky news @JensGleichmann), ######## Javascript is disabled or is unavailable in your browser.

ENI-3 Name System (DNS). In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. Extracting the table STXL. Changes the replication mode of a secondary site. 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. The parameter listeninterface=.global in the section [system_replication_communication] is used for system replication. For more information about how to attach a network interface to an EC2 Below query returns the internal hostname which we will use for mapping rule. 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. 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. So I think each host, we need maintain two entries for "2. In multiple-container systems, the system database and all tenant databases
SAP HANA Native Storage Extension ("NSE") is the recommended approach to implementing data tiering within an SAP HANA system. You provision (or add) the dynamic tiering service (esserver) on the dedicated host to the tenant. 1. overwrite means log segments are freed by the
The instance number+1 must be free on both
Keep the tenant isolation level low on any tenant running dynamic tiering. 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. All mandatory configurations are also written in the picture and should be included in global.ini. To learn internal, and replication network interfaces. If you want to force all connection to use SSL/TLS you have to set the sslenforce parameter to true (global.ini). no internal interface found, listeninterface, .internal , KBA , HAN-DB , SAP HANA Database , Problem . 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.. But the, SAP app server on same machine, tries to connect to mapped external hostname and if tails of course. The values are visible in the global.ini file of the tenant database but cannot be modified from the tenant database. 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. -ssltrustcert have to be added to the call. With MDC (or like SAP says now container/tenants) you always have a systemDB and a tenant. 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. I hope this little summary is helping you to understand the relations and avoid some errors and long researches. Scale-out and System Replication(2 tiers), 4. Dynamic tiering adds smart, disk-based extended storage to your SAP HANA database. Now you have to go to the HANA Cockpit Manager to change the registered resource to use SSL. The XSA can be offline, but will be restarted (thanks for the hint Dennis). Deploy SAP Data Warehouse Foundation (Data Lifecycle Manager) Delivery Unit on SAP HANA. Chat Offline. SAP HANA system replication is used to address SAP HANA outage reduction due to planned maintenance, fault, and disasters. ALTER SYSTEM ALTER CONFIGURATION ( global.ini, SYSTEM ) SET( customizable_functionalities, dynamic_tiering ) = true. Or see our complete list of local country numbers. If you plan to use storage connector APIs, you must configure the multipath.conf and global.ini files before installation. Questo articolo descrive come distribuire un sistema SAP HANA a disponibilit elevata in una configurazione con scalabilit orizzontale. For this it may be wise to add an IP label, which means an own DNS record with name and IP, for each service. SAP HANA 1.0, platform edition Keywords. interfaces similar to the source environment, and ENI-3 would share a common security group. First time, I Know that the mapping of hostname to IP can be different on each host in system replication relationship. Using HANA studio. Determine which format your key file has with a look into it: If it is a PKCS#12 format you have to follow this steps (there are several ways, just have a look at the openssl documentation): a) Export the keys in PKCS#12 transfer format: The HANA DB has to be online. As you create each new network interface, associate it with the appropriate global.ini -> [communication] -> listeninterface : .global or .internal 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. to use SSL [, Configure HDB parameters for high security [, Pros and Cons certification collections [, HANA Cockpit (HTTPS)=> sapcontrol (SAP Start Service / sapstartsrv), HANA Cockpit (JDBC) => Database Explorer / Monitoring => Resources, Native Client Connection (ODBC/JDBC) => HANA. Starts checking the replication status share. need to specify all hosts of own site as well as neighboring sites. Post this, Installation of Dynamic Tiering License need to done via COCKPIT. This is necessary to start creating log backups. Credentials: Have access to the SYSTEM user of SystemDB and " <SID>adm " for a SSH session on the HANA hosts. Although various materials and documents for HANA networks have been available to ease your implementations and re-configurations, you might have found it time-consuming and experienced a hard time to see a whole picture at a glance. * Internal networks are physically separate from external networks where clients can access. documentation. Net2Source Inc. is an award-winning total workforce solutions company recognized by Staffing Industry Analysts for our accelerated growth of 300% in the last 3 years with over 5500+ employees . In a traditional, bare-metal setup, these different network zones are set up by having SAP HANA dynamic tiering is a native big data solution for SAP HANA. You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering. HI DongKyun Kim, thanks for explanation . Check all connecting interfaces for it. documentation. is configured to secure SAP HSR traffic to another Availability Zone within the same Region. 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). 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. replication. For more information, see Configuring Instances. properties files (*.ini files). You can also create an own certificate based on the server name of the application (Tier 3). Be careful with setting these parameters! 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. The OS process for the dynamic tiering host is hdbesserver, and the service name is esserver. It must have the same software version or higher. 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!

For more information, see Standard Roles and Groups. Internal communication is configured too openly 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. 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). Recently we started receiving the alerts from our monitoring tool: A service in this context means if you have multiple services like multiple tenants on one server running. # 2020/4/15 Inserted Vitaliys blog link + XSA diagnose details In this case, you are required to add additional NIC, ip address and cabling for site1-3 replication. Both SAP HANA and dynamic tiering hosts have their own dedicated storage. 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. I have not come across much documentation on this topic and not sure if any customer experienced such a behavior so put up a post to describe the scenario An elastic network interface is a virtual network interface that you can attach to an 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 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. 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. In this example, the target SAP HANA cluster would be configured with additional network When set, a diamond appears in the database column. 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. all SAP HANA nodes and clients. instances. A separate network is used for system replication communication. For sure authorizations are also an important part but not in the context of this blog and far away from my expertise. To learn more about this step, see Configuring Hostname Resolution for SAP HANA System Replication in the SAP the secondary system, this information is evaluated and the
If you want to be flexible in case of changing the server (HW change / OS upgrade), you need multiple certificates connected to different hostnames. number. Please provide your valuable feedback and please connect with me for any questions. 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. 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. 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. provide additional, dedicated capacity for Amazon EBS I/O. There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*. Figure 10: Network interfaces attached to SAP HANA nodes. Single node and System Replication(3 tiers)", for example, is that right? Overview. groups. 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. Thanks a lot for sharing this , it's a excellent blog . the global.ini file is set to normal for both systems. About this page This is a preview of a SAP Knowledge Base Article. A security group acts as a virtual firewall that controls the traffic for one or more 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). 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. Above configurations are only required when you have internal networks. Introduction. You can copy the certificate of the HANA database to the application server but you dont need to (HANA on one Server Tier 2). 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 If you answer one of the questions negative you should wait for the second part of this series , ########### * 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/.
