RE: Stored Procedure performance

["Haas, Matt" <Matt.Haas@xxxxxxxxxxxxxxxxxxx>]

Phil,

Are you doing a disconnect from AS400B after every call to the stored procedure 
perhaps? Doing this will cause the communications job to end on AS400B.

I think I would start by looking to see how long the section of code that calls 
the stored procedure is taking to execute. I'd look at the numbers on both 
AS400A  and AS400B so you can get some sense of the how much network latency is 
adding to the delay.

Subject: Stored Procedure performance


I have a stored procedure (which is an RPG pgm) on AS400B which is called from
an SQLRPGLE pgm on AS400A.  These AS400's are in different parts of the country.
 The pgm on AS400A reads about 7 million records and calls the stored procedure
about 4 million times. 

Performance is abysmal.  I thought performance would be better than DDM'ing to
two files but it is actually worse.

Are there any ways to improve performance?  Or to determine where the
performance problem is?  Does the stored procedure job on AS400B end after each
call?

Thanks,

Phil
