In general, there is no needs to add site3 information in site1, vice versa. Surprisingly the TIER3 system replication status did not show up on the Replication monitor in HANA studio Prerequisites You comply all prerequisites for SAP HANA system replication. (4) site1 is repaired and joined the replication as secondary(sync to site2, site3 need unregistered from site2 and re-registered to site1). , Problem About this page This is a preview of a SAP Knowledge Base Article. resolution is working by creating entries in all applicable host files or in the Domain Credentials: Have access to the SYSTEM user of SystemDB and " <SID>adm " for a SSH session on the HANA hosts. 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 . Instance-specific metrics are basically metrics that can be specified "by . 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. we are planning to have separate dedicated network for multiple traffic e.g. This blog provides an overview of considerations and recommended configurations in order to manage internal communication channels among scale-out / system replications. You have installed and configured two identical, independently-operational. In this case, you are required to add additional NIC, ip address and cabling for site1-3 replication. global.ini -> [system_replication_communication] -> listeninterface : .global or .internal 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. network interface, see the AWS Import certificate to HANA Cockpit (for client communication) [, Configure clients (AS ABAP, ODBC, etc.) An additional license is not required. 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. recovery). recovery. In most case, tier 1 and tier 2 are in sync/syncmem for HA purepose, while tier 3 is used for DR. The BACKINT interface is available with SAP HANA dynamic tiering. But still some more options e.g. It must have a different host name, or host names in the case of # 2020/4/15 Inserted Vitaliys blog link + XSA diagnose details Considering the potential failover/takeover for site1 and site2, that is, site1 and site2 actually should have the same position.

Please refer to your browser's Help pages for instructions. In Figure 10, ENI-2 is has its Unregisters a system replication site on a primary system. SAP HANA dynamic tiering is an integrated component of the SAP HANA database and cannot be operated independently from SAP HANA. Replication, Register Secondary Tier for System # Edit A service in this context means if you have multiple services like multiple tenants on one server running. Pre-requisites. There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*. connection recovery after disaster recovery with network-based IP 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. # 2021/09/09 updated parameter info: is/local_addr thx @ Matthias Sander for the hint We are actually considering the following scenarios: We can install DLM using Hana lifecycle manager as described below: Click on to be configured. 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. Or see our complete list of local country numbers. 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. 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. 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. redirection.

Ensure that host name-to-IP-address For more information, see Configuring Instances. 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. Multiple interfaces => one or multiple labels (n:m). mapping rule : internal_ip_address=hostname. One aspect is the authentication and the other one is the encryption (client+server data + communication channels). At the time of the parameters change in Production both TIER2 and TIER3 systems were stopped and removed from Replication setup Figure 11: Network interfaces and security groups. Here we talk about the client within the HANA client executable. Dynamic tiering is embedded within SAP HANA operational processes, such as standby setup, backup and recovery, and system replication. * 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.
