SAP HANA supports asynchronous and synchronous replication modes. If you've got a moment, please tell us what we did right so we can do more of it. It is also possible to create one certificate per tenant. Your application automatically determines which tier to save data to: the SAP HANA in-memory store (the hot store), or extended storage (the warm store). Chat Offline. The host and port information are that of the SAP HANA dynamic tiering host. 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. 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. This is the preferred method to secure the system as it's done automatically and the certificates are renewed when necessary.
