Re: RPG and Threads

If it were me, I'd use the spawn() api, which is somewhat similar to
SBMJOB, but you can track when it completes with a "handle", so the parent
job can coordinate everything completing in whatever step you need. Also,
if it were me, I'd put as little detail work into a test as possible to
determine if there is any performance benefit to this. Its quite possible
that there would not be if you're I/O constrained anyway.

One other thought. You could setup a test with SBMJOBs. It might not be
perfect, but you could see if you get some kind of performance benefit
before you dig too deep into this.

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.
