Re: Different processing times...why?

["Ray Nainy" <ray_456@xxxxxxxxxxx>]

Mike,

LR is set on before the program gets terminated. So, the only possible
reason I can see is the records being held in memory for a short period of
time.
Is there any option to rerieve the records much faster when the RPG program
is called for the first time?

We have an RPG program that reads approximately 4500 records from
file A and reads matching records in file B using account number.
File B has a total of 2 million records.
It takes about 60 to 70 seconds to complete the processing when the program
is called for the first time. But it takes only 3 to 4 seconds to complete
the processing, when the program is called again 2nd or 3rd or 4th or
5th...time. Processing time is 60 to 70 seconds only for the first call.
This happens again if the session is idle for 20 minutes or more. We
couldn't find out why is this processing time more only for the first call
to the RPG program. We verified and found that this problem exist
anytime, irrespective of the peak/non-peak hours of the day.

Any help is greatly appreciated.

Ray
