After some more checks we identified the listeninterface and internal_hostname_resolution parameters were not updated on TIER2 and TIER3 global.ini -> [internal_hostname_resolution] : Stops checking the replication status share. need not be available on the secondary system. You provision (or add) the dynamic tiering service (esserver) on the dedicated host to the tenant. In the step 5, it is possible to avoid exporting and converting the keys. Single node and System Replication(3 tiers), 3. mapping rule : internal_ip_address=hostname. These are all pretty broad topic and for now we will focus on the x.509 certificates for encryption of the communication channels between server and clients. Which communication channels can be secured? Is it possible to switch a tenant to another systemDB without changing all of your client connections? Before drawing the architecture, I hope this blog would help to get better understanding of networks required in HANA database regardless of the complexity. We are talk about signed certificates from a trusted root-CA. In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. the same host is not supported. It must have the same system configuration in the system
So I think each host, we need maintain two entries for "2. 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. the secondary system, this information is evaluated and the

A service in this context means if you have multiple services like multiple tenants on one server running. If you answer one of the questions negative you should wait for the second part of this series , ########### alter system alter configuration ('xscontroller.ini','SYSTEM') set ('communication','jdbc_ssl') = 'true' with reconfigure; You can use the same procedure for every other XSA installation. , Problem About this page This is a preview of a SAP Knowledge Base Article. 2478769 Obtaining certificates with subject Alternative Name (SAN) within STRUST 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. To give context - We are using HANA SSL certificates, which are valid for 1 year and before it gets expire we need to renew it, so we want to do Monitoring to get alerts of it either by Cockpit/ Splunk or other home grown tools via Perl/any other scripting, so any one knows more about it?? must be backed up. Because site1 and site2 usually resides in the same data center but site3 is located very far in another data center. global.ini -> [system_replication_communication] -> listeninterface : .global or .internal * You have installed internal networks in each nodes. Keep the tenant isolation level low on any tenant running dynamic tiering. Refresh the page and To Be Configured would change to Properly Configured. 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. Below query returns the internal hostname which we will use for mapping rule. 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. can use elastic network interfaces combined with security groups to achieve this network To set it up is one task, to maintain and operate it another. * sl -- serial line IP (slip) For more information about how to attach a network interface to an EC2 (2) site2 take over the primary role; 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. Be careful with setting these parameters! To learn 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. Dynamic tiering is embedded within SAP HANA operational processes, such as standby setup, backup and recovery, and system replication. SAP Real Time Extension: Solution Overview.

You use this service to create the extended store and extended tables. +1-800-872-1727. Create new network interfaces from the AWS Management Console or through the AWS CLI. I just realized that the properties 'jdbc_ssl*' have been renamed to "hana_ssl" in XSA >=1.0.82. * as internal network as described below picture. SAP HANA System Target Instance. 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). 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. Actually, in a system replication configuration, the whole system, i.e. Considering the potential failover/takeover for site1 and site2, that is, site1 and site2 actually should have the same position. configure security groups, see the AWS documentation. 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. We are not talking about self-signed certificates. enables you to isolate the traffic required for each communication channel. documentation. Step 1. Surprisingly the TIER3 system replication status did not show up on the Replication monitor in HANA studio Name System (DNS). See Ports and Connections in the SAP HANA documentation to learn about the list 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).
