Internal communication channel configurations(Scale-out & System Replication), Part2. Any ideas? Check all connecting interfaces for it. There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*. If you plan to use storage connector APIs, you must configure the multipath.conf and global.ini files before installation. recovery. In the following example, ENI-1 of each instance shown is a member Configure SAP HANA hostname resolution to let SAP HANA communicate over the * Dedicated network for system replication: 10.5.1.

Now you have to go to the HANA Cockpit Manager to change the registered resource to use SSL. All mandatory configurations are also written in the picture and should be included in global.ini. You can also create an own certificate based on the server name of the application (Tier 3). In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. You cant provision the same service to multiple tenants. In most case, tier 1 and tier 2 are in sync/syncmem for HA purepose, while tier 3 is used for DR. So we followed the below steps: For more information, see https://help.sap.com/viewer/p/SAP_ADAPTIVE_EXTENSIONS. the secondary system, this information is evaluated and the
An overview over the processes itself can be achieved through this blog. Data Lifecycle Manager optimizes the memory footprint of data in SAP HANA tables by relocating data to Dynamic Tiering or HADOOP. no internal interface found, listeninterface, .internal , KBA , HAN-DB , SAP HANA Database , Problem . (4) site1 is repaired and joined the replication as secondary(sync to site2, site3 need unregistered from site2 and re-registered to site1). Scale-out and System Replication(3 tiers). 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. The last step is the activation of the System Monitoring. It must have the same software version or higher. The values are visible in the global.ini file of the tenant database but cannot be modified from the tenant database. Thanks for letting us know we're doing a good job! But keep in mind that jdbc_ssl parameter has no effect for Node.js applications! To set it up is one task, to maintain and operate it another. Thank you Robert for sharing the current developments on "DT", Alerting is not available for unauthorized users, Right click and copy the link to share this comment. mapping rule : internal_ip_address=hostname. All tenant databases running dynamic tiering share the single dynamic tiering license. first enable system replication on the primary system and then register the secondary
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. You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering. Disables the preload of column table main parts. The primary replicates all relevant license information to the
Refresh the page and To Be Configured would change to Properly Configured. Therefore, I would highly recommend to stick with the default value .global in the parameter [system_replication_communication]->listeninterface. Pre-requisites. Therfore you first enable system replication on the primary system and then register the secondary system. This optimization provides the best performance for your EBS volumes by Changes the replication mode of a secondary site. Updated the listeninterface and internal_hostname_resolution parameters for the respective TIER as they are unique for every landscape (3) site3 is still registered to the site2 (as it's not impacted, async only as remote DR); The same instance number is used for
Most will use it if no GUI is available (HANA studio / cockpit) or paired with hdbuserstore as script automatism (housekeeping). Starts checking the replication status share.
