  • Patent number: 10366105
    Abstract: A processor-implemented method for replicating structured query language (SQL) in a heterogeneous replication environment is provided. The method includes receiving a first statement for a multi-row operation, whereby the multi-row operation is directed to one or more tables of a database, and whereby the first statement includes a text of a SQL statement in a DBMS transaction log. The method also provides for evaluating whether to create a source tree structure from the received first statement. In response to creating the source tree structure, the method evaluates whether the source tree structure is transformable. The method transforms the source tree structure to a target tree structure in response to evaluating that the source tree structure is transformable.

  • Patent number: 10089375
    Abstract: According to one embodiment of the present invention, during database replication from a source database to a target database, operations applied to the source database are transferred as target operations and applied to the target database. A request from a requestor to idle a specified database object is received during the database replication. In response to receiving the request, transference of the target operations for the specified database object from the source database to the target database is terminated and target operations for the specified database object on the target database are monitored. In response to no target operations being applied to the specified database object on the target database, replication of the specified database object is suspended and the requestor is notified when the idling of the specified database object has completed.
