datasets in grid environment

Can someone help me in finding how DataStage manages to access datasets created in a grid environment, since the config file used to create may be different from the one that is used to access the dataset( in a different job, or in a different run) and it may or may not include the original nodes used to create the .ds .

When reading from a Data Set in a grid environment, a virtual and read-only Data Set is constructed using the nodes that were used when the Data Set is written. That information is stored in the Data Set descriptor file and can therefore be re-used when reading from the Data Set. There is also an option ( -x if I recall correctly) to force the orchadmin command to do the same thing.
