Does the file exist? How was is created? For this to work, it must - must - have been created with a Data Set stage; it is a common mistake to believe that one can create a Data Set with a Sequential File stage.

thanks,

DataStage parallel extender jobs use data sets to
manage data within a job.

Hello,

normally DataStage creates the file. But the directory must exist and the DataStage user needs the according permissions to be allowed to create the file...

Hope this helps

Thanks to all for the replies. can any one tell me what is the default path ?plzzzzzzzzz

There is no "default path". You must use a Data Set stage to create a Data Set. The File property must be a pathname with the file name ending in ".ds". If you do not provide a pathname, the ".ds" file is created in the project directory. This file is the Data Set control file; the actual data files are created in the directories specified in the configuration file as disk resources.
