Abstract: Replicating a tenant database includes receiving at a source system a first request from a target system for replicating a first tenant database of the source system, which includes one or more first servers. Characteristics of the one or more first servers are sent to the target system to generate at the target system a second tenant database including one or more second servers. Each second server corresponds to one first server and has the same characteristics as the corresponding first server. Information from each first server is replicated, in an asynchronous mode, to the corresponding second server through a communication channel that is established between each first server and the second server. Upon receiving a second request for stopping the replication, a synchronous mode of processing statements from client applications of the first tenant database is entered. Related apparatus, systems, techniques and articles are described.

Abstract: Testing a database replication system within a multi-container system architecture comprises receiving a first request for creating a database recovery system within a multi-container system architecture. The multi-container system architecture is configured to contain a plurality of tenant databases and a system database, and the database recovery system includes a primary system and a secondary system. The primary system is then identified from the information in the first request. Upon identification, a first tenant database included in the plurality of tenant databases is determined that corresponds to the identified primary system. Upon determining the first tenant database, a second tenant database of the plurality of tenant database is generated that corresponds to the secondary system, and which is enabled to test replicating information that would otherwise be associated with the first tenant database. Related apparatus, systems, techniques and articles are also described.
