Abstract
A technique for selectively dummying a data pipe transparent to a writer application is provided. A writer application writes data to a local data pipe or a cross-system data pipe and one or more reader applications read data from the data pipe. The technique involves determining when a last reader application of the at least one or more reader applications closes the data pipe before the writer application has completed writing data to the data pipe. Upon determining this condition, further writing of data to the data pipe by the writer application is transparently prevented. While transparently preventing writing to a dummied data pipe, writing of data to a fitting, e.g., for a permanent record, can proceed.
