Lim,
 
With that many records, you're still probably looking at a long
runtime, (I doubt it would be 3 hours, but I don't know your
environment).
 
If none of the suggestions given here result in the performance gains
you seek, you may have to punt and rethink - as other's have
suggested:
 
Modify the programs that update and add to the file so that they
maintain this summary file as the initial file changes.   Then create
the summary one last time using existing logic, and then install the
changes.
 
hth,

> Our telephone master file is splitted across two AS400.  One has 22M+ and
the other has 18M+ records.  The summary file needs to combine the record
from the two AS400.  To copy such a big file across to another system, index
it and run the process is probably too time consuming.  The plan is to
create summary file on each system first, then somehow combine them.  Not
sure if I can beat the 3 hours time of the existing process.  Is going to be
fun and probably will need some helps from you folks again.
