ABSTRACT:
A system and method for a computer based system having one or more consuming DBMSs and one or more producing DBMSs such that the producing DBMSs produce workfiles for the consuming DBMSs. A producing DBMS uniquely identifies the bufferpool pages comprising a workfile, uniquely identifies the workfile, and flushes only the bufferpool pages corresponding to the workfile to a storage device. The producing DBMS further notifies the consuming DBMS that the workfile is available and receives a reply from the consuming DBMS indicating that the consuming device retrieved the data from the storage device. The consuming device receives notification from the producing DBMS, retrieves the workfile, and replies to the producing DBMS that it has retrieved the workfile.
