Hi All,
I am new to Parallel jobs. I tried retrieving the data thro dataset stage, it shows the following error. My file name is dataset1.ds.
Error Message:
dataset1.ds is not an ORCHESTRATE Data. Set descriptor.
But the same fil, if i use seq file stage, its working with same layout.
Please give me the solution for this.
Thanks and Regards,
SKP

Data sets and Sequential files are different types. What you are trying is like attempting to read an Oracle table with a sequential file stage. You can only read Datasets with the Dataset stage.

Are you sure that you had created the file using dataset stage? I doubt the file is a valid dataset?

Yes, I am sure, I have created the file as dataset1.ds,
the record is,
101,Michael,States
205,Rhude,Miluwake
like this.....

Making the name end in ".ds" doesn't create a dataset. Did you write this file with a sequential file stage or a Dataset stage?

If it can be read with a Sequential File stage it was created with a Sequential File stage, or something at the command (operating system) level. It is not a Data Set, which is a parallel structure.

Thanks a lot Friend, I got it.
Instead writing first to the Dataset, I just started with reading from the dataset by creating the file with .ds. Now its working.
Thanks to everyone of you,
