In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. Name System (DNS). (2) site2 take over the primary role; It would be difficult to share the single network for system replication. 3. So site1 & site3 won't meet except the case that I described. Global Network Scale out of dynamic tiering is not available. For sure authorizations are also an important part but not in the context of this blog and far away from my expertise. You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering. Started the full sync to TIER2 systems, because this port range is used for system replication The XSA can be offline, but will be restarted (thanks for the hint Dennis). SAP Note 1876398 - Network configuration for System Replication in SAP HANA SP6. /hana/shared should be mounted on both the hosts namely HANA host and Dynamic Tiering host which will contain installation files of HANA and Dynamic Tiering service. This is mentioned as a little note in SAP note 2300943 section 4. How you can secure your system with less effort? Here we talk about the client within the HANA client executable. 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. For scale-out deployments, configure SAP HANA inter-service communication to let Connection to On-Premise SAP ECC and S/4HANA. * In the first example, the [system_replication_communication]listeninterface parameter has been set to .global and only the hosts of the neighboring replicating site are specified. We are actually considering the following scenarios: multiple physical network cards or virtual LANs (VLANs). with Tenant Databases. Thanks for the further explanation. The latest release version of DT is SAP HANA 2.0 SP05. As you may read between the lines Im not a fan of authorization concepts.

System replication between two systems on Trademark. Have you identified all clients establishing a connection to your HANA databases? If set on 4. Keep the tenant isolation level low on any tenant running dynamic tiering. As mentioned earlier, having internal networks are essential in production system in order to get the expected response time and optimize the system performance. This implies that if there is a standby host on the primary system it Internal communication is configured too openly savepoint (therefore only useful for test installations without backup and 2386973 - Near Zero DowntimeUpgradesforHANADatabase 3-tierSystemReplication. 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. Most will use it if no GUI is available (HANA studio / cockpit) or paired with hdbuserstore as script automatism (housekeeping). Figure 11: Network interfaces and security groups. well as for SAP HSR, Storage zone to persist SAP HANA data in the storage infrastructure for SAP HANA System, Secondary Tier in Multitier System Replication, or To learn more about this step, see Configuring Hostname Resolution for SAP HANA System Replication in the SAP Or see our complete list of local country numbers. , Problem. tables are actually preloaded there according to the information Set Up System Replication with HANA Studio. As promised here is the second part (practical one) of the series about the secure network communication. Copy the commands and deploy in SQL command. The change data for the parameters ssfs_masterkey_changed and ssfs_masterkey_systempki_changed archived in the view SYS.M_HOST_INFORMATION is changed. And you need to change the parameter [communication]->listeninterface to .internal and add internal network entries as followings. more about security groups, see the AWS If you've got a moment, please tell us what we did right so we can do more of it. The secondary system must meet the following criteria with respect to the It's free to sign up and bid on jobs. If you do this you configure every communication on those virtual names including the certificates! * en -- ethernet system. In HANA studio this process corresponds to esserver service. Configuring SAP HANA Inter-Service Communication in the SAP HANA RFC Module. Overview. For more information, see https://help.sap.com/viewer/p/SAP_ADAPTIVE_EXTENSIONS. 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. # 2021/04/26 added PIN/passphrase option for sapgenpse seclogin For your information, having internal networks under scale-out / system replication is a mandatory configuration in your production sites. The last step is the activation of the System Monitoring. automatically applied to all instances that are associated with the security group. ENI-3 Scale-out and System Replication(2 tiers), 4. (3) site3 is still registered to the site2 (as it's not impacted, async only as remote DR); Contact us. Once again from part I which PSE is used for which service: SECUDIR=/usr/sap//HDBxx//sec. mapping rule : internal_ip_address=hostname. Stopped the Replication to TIER2 and TIER3 and removed them from the system replication configuration need not be available on the secondary system. Or see our complete list of local country numbers. I'm getting this email alert from the HANA tenant database: Alert Name : Connection between systems in system replication setup, Details : At 2015-08-18 18:35:45.0000000 on hostp01:30103; Site 2: Communication channel closed. There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*. 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 primary hosts listen on the dedicated ports of the separate network only, and incoming requests on the public interfaces are rejected. At the time of the parameters change in Production both TIER2 and TIER3 systems were stopped and removed from Replication setup If you set jdbc_ssl to true will lead to encrypt all jdbc communications (e.g. Before we get started, let me define the term of network used in HANA. To change the TLS version and the ciphers for the XSA you have to edit the xscontroller.ini. Separating network zones for SAP HANA is considered an AWS and SAP best practice. -ssltrustcert have to be added to the call. Configuring SAP HANA Inter-Service Communication, Configuring Hostname Resolution for SAP HANA System Replication, Configuration for logical network separation, AWS (Addition of DT worker host can be performed later). DT service can be checked from OS level by command HDB info. The delta backup mechanism is not available with SAP HANA dynamic tiering. mapping rule : internal_ip_address=hostname. Single node and System Replication(3 tiers)", for example, is that right? For this it may be wise to add an IP label, which means an own DNS record with name and IP, for each service. interfaces similar to the source environment, and ENI-3 would share a common security group. Only set this to true if you have configured all resources with SSL. 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. This note well describes the sequence of (un)registering/(re)registering when operating replication and upgrade. 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. Tertiary Tier in Multitier System Replication, Operations for SAP HANA Systems and Instances, Enable / Disable Fullsync System For instance, you have 10.0.1.
