Abstract: A method and means for improving the performance of distributed computer systems including a file server and a plurality of remote workstations. A system workstation issues a request from one of the remote workstations to open a batch file resident on the file server in a sharing mode. The request is automatically converted into a request to open the file in an OPlocked/OPbatched exclusive mode. The file server then determines whether the requested batch file has been opened by another workstation. The requested file is opened in an OPlocked/OPbatched exclusive mode if the requested file is not currently open, wherein the batch file is copied to a workstation and executed locally while keeping the batch file open on the file server. The file is opened in a sharing mode if the requested batch file is currently open. The batch file is written to the file server and closed and the system reverts to a sharing mode if the batch file is opened in the OPlocked/OPbatched exclusive mode and the batch file is requested by another of the system workstations.
