Duplicate File References

Summary

Verifies that a sequential file is…

• only referenced once in a DataStage Flow’s Sequential File, Complex Flat File, or DataSet stages, and
• not simlutaneously being read and written in the same DataStage Flow

Description

Sometimes developers will copy and paste stages rather than adding a new stage from the palette. In doing so there is a risk that the developer may not update the reference to the filename property which may result in incorrect processing being performed by the DataStage flow.

Actions

Ensure that a file is only referenced once in a DataStage flow.
