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.
