RE: How to optimize COPY *ADD

[Dimitri Efimov <defimov@xxxxxxxxxxxx>]

That's correct, we are copying daily built file to history file, the point
is - the history file has more than 200 mln. of records, even more - it has
18 index files. So it's impossible to find "keyed sequence". 

But I'm going to try the solution Buck's solution ("Multiple CPYF commands
in parallel might be better if you have a good way to partition the records
such as FROMRCD(1)
TORCD(1000000)...FROMRCD(1000001) TORCD(2000000) ...) hope it will work. 

Thanks a lot

If I understand you correctly, you're copying a file that's built daily to a
history file.  Six hours sounds like a long time for 4,000,000 records.  Are
you copying in keyed sequence?  If you are you could try fromrcd(1).  

Otherwise, you could break it down into "simultaneous" submitted jobs using
fromrcd(x) torcd(y).
