Each tenant requires a dedicated dynamic tiering host. System replication overview Replication modes Operation modes Replication Settings 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. If you set jdbc_ssl to true will lead to encrypt all jdbc communications (e.g. 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. Any ideas? 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. Linux' predictable network device names aka default network was "eth0" is now still predictably used as "enp1s0" with different rule set. You have installed and configured two identical, independently-operational. A security group acts as a virtual firewall that controls the traffic for one or more Source: SAP 1.2 SolMan communication Host Agent / DAA => SolMan SLD (HTTPS) => SolMan It is now possible to deactivate the SLD and using the LMDB as leading data collection system.

But keep in mind that jdbc_ssl parameter has no effect for Node.js applications! General Prerequisites for Configuring SAP
Chat Offline. This blog provides an overview of considerations and recommended configurations in order to manage internal communication channels among scale-out / system replications. By default, this enables security and forces all resources to use ssl. Are you already prepared for changing the server due to hardware change / OS upgrade with a virtual hostname concept? Set Up System Replication with HANA Studio. Name System (DNS). You have verified that the log_mode parameter in the persistence section of
SAP HANA dynamic tiering is an integrated component of the SAP HANA database and cannot be operated independently from SAP HANA. For more information, see: But still some more options e.g. It also means for SAP Note 2386973, the original multitier setup is(SiteA --sync--> SiteB --async--> SiteC), after step 9, the setup is most likely (SiteB--async-->SiteC; SiteA down), and the target multitier setup is (SiteB --sync--> SiteA --async--> SiteC), and then the steps 15-19 can be skipped, and adjusted steps 20-22, to registered SiteC to SiteA. Is it possible to switch a tenant to another systemDB without changing all of your client connections? So site1 & site3 won't meet except the case that I described. The parameter listeninterface=.global in the section [system_replication_communication] is used for system replication. Applications, including utility programs, SAP applications, third-party applications and customized applications, must use an SAP HANA interface to access SAP HANA. system. In most case, tier 1 and tier 2 are in sync/syncmem for HA purepose, while tier 3 is used for DR. I hope this little summary is helping you to understand the relations and avoid some errors and long researches. Certificate Management in SAP HANA When complete, test that the virtual host names can be resolved from SAP is using mostly one certificate for all components (host agent, DAA, SystemDB, Tenant) which belongs to the physical hostname (systempki). SAP Note 1834153 . Disables the preload of column table main parts. Figure 12: Further isolation with additional ENIs and security For more information, see Assigning Virtual Host Names to Networks. As you may read between the lines Im not a fan of authorization concepts. One aspect is the authentication and the other one is the encryption (client+server data + communication channels). instances. -Jens (follow me on Twitter for more geeky news @JensGleichmann), ######## But the, SAP app server on same machine, tries to connect to mapped external hostname and if tails of course. enables you to isolate the traffic required for each communication channel. There is already a blog about this configuration: https://blogs.sap.com/2014/01/17/configure-abap-to-hana-ssl-connection/ SAP HANA Native Storage Extension ("NSE") is the recommended approach to implementing data tiering within an SAP HANA system. SAP HANA supports asynchronous and synchronous replication modes. ALTER SYSTEM ALTER CONFIGURATION ( global.ini, SYSTEM ) SET( customizable_functionalities, dynamic_tiering ) = true.
