End of report.

Has any body faced like this ? please help me .

Thanks in advance

What is the partitioning done on the Oracle Enterprise Stage?

If you have used RoundRobin, could you try with Hash/sort on Target Table Key Columns.

After displaying 60% the process just hangs forever? Can you monitor system performance from UNIX (I like "vmstat") to see if the machine is still busy?

Thanks for all for your suggestions ...today i will follow your advice and let you know the outcome

Perhaps a bottleneck downstream (prime suspect being the DB write) is causing a buffer to fill and is throttling the read from the sequential file? If you remove the Oracle stage from the flow and write to a dataset, how does it behave? I'd also take a dump of the score out of your original code.
