Re: RPG and Threads

Hi Douglas,

Before you go to lengthy effort to multi-thread the job, consider posting
the SQL here for optimization.

Is the SQL set oriented, or single row at a time oriented?

If the SQL is single row at a time oriented (or close to it), converting it
to set based processing will most likely shave off most of that run time.

subject: RPG and Threads


Does anyone have a simple program example (or know where I can find one)
for an RPG program that creates thread jobs? I am wanting to know if it is
possible for one RPG program (or CL) to start 4 or 5 threads, and each
thread would process one part of a file, instead of having one program
process the file from beginning to end. This is a read and summarize
application that is being converted to SQL, but even with SQL, it takes a
long (7+ hours) to process the whole file.
