Hi,
Please give me solution for the following error:
Sequential_File_8: When checking operator: A sequential operator cannot preserve the partitioning
of the parallel data set on input port 0.

I guess the probability is that your RCP is on for the previous stage which already has a partitioning set,or check whether its put as same.
A printer consists of 3 main parts: the case, the jammed paper tray and the blinking red light.

This is not an error, but a warning. DataStage is stating that the partitions of the input stream are being changed to just 1 stream because you are writing to a sequential file. This is documented in the Parallel Job Developers Guide .

The same has been discussed several times.
May be you can avoid this warning by Clear ing the partition in the previous stage output.
Impossible doesn't mean 'it is not possible' actually means... 'NOBODY HAS DONE IT SO FAR'
