Hi,
Should the source files being processed via ETL should reside on the ETL server or database server.
Thanks
Bob.

ETL server.
I am not sure if we can keep it in DB server and then share it from there but the best way Iguess is to keep it in ASCl server.

On the DataStage server is better, because you're not introducing the network as a bottleneck.
However, the only actual requirement is accessible from the DataStage server.

Hi Bob,
Ray is right.
A while ago we tried NFS and found out that the throughput dropped by 5 times.
But if your company can afford a high-end SAN with fiber links, you'll be in heaven...
or close to...

Hi,
Can the time spent on droping the source from Database to ETL server can be compenstated by extracting directly from Database.
Assuming source need to be droped for every run.
