You don't have to copy .Type30 - it's empty. But it does need to be there. It signals to DataStage that this directory is a hashed file. Without it DataStage treats it as an ordinary directory, and ... Where is this .type30 file located? I don't find it in the hashed file directory. I am using a dy...

Yes, provided that the hardware is compatible (primarily byte order). For example, copying from a non-Intel chip to an Intel chip would cause difficulties, because every pair of bytes in the hashed ... Ok, but after I copied the hashed file cannot be read. It gives me junk characters. This is how I...

I think I have figured it out why. The 2 links into the LC complete at different time. One link is faster than the other. When one of the links has completed and the other is still in progress, the output link of LC will complete irregardless of the other link(s) that are still in progress. Therefor...

I turned on the trace only for debugging purposes. Else, there is no reason why I should do so as it will take up more resources. Anyway, even without the trace turned on, it is still as slow if not slower. The job doesn't do any sorting. Anyway, there is no sort option in the merge stage. The trans...

Would appreciate if anyone can advise. To add to the above:- job 1 merges file ...
