RE: SYS21 - DRP Performance

["Wood, Steve" <swood@xxxxxxxxxxxxxxxx>]

Peter,

        what you may want to look at doing is to examine the program that
uses the SQL statements and create logical views that closely match the SQL
statements in the way they select and order the file. I've had a similar
problem to this at a customer I work at and the time to build an SQL view
went from minutes to seconds. Although you will not have to modify the
program to use the new logical views the optimizer within SQL will try and
search for a logical file that closely matches its requirements and use that
access path in preference to building one of it's own.

        Hope this helps.

        Steve Wood

Subject: SYS21 - DRP Performance


Hello List

Has anybody found performance problems when running
DRP? Specifically the use of SQL seem to negate the
benefits of selection by eg item or planner range, or
Net Change.

Any ideas how to get around this, short of re-writing
the programs to use logicals?

Thanks
