Re: I think I need multi-threading but I'm only on V5R4M5

just some ideas:

- parallel database feature might help (its fantastic, but expensive)
- using a multithreading enabled language (even RPG 7.1, I would not recommend for this, it has no support for synchronisation) like C, C++ or Java
- the SBMJOB is possible too, the jobs could produce a temporary table, used by the main Job after waiting for termination of the sattelit Jobs

Subject: I think I need multi-threading but I'm only on V5R4M5

Well I have come upon a project where I think I need multi-threading in
RPGLE but I am only on V5R4M5.

Here is the scenario...
We have a file that we need to search. There are 7 fields in each record
that can be searched. As few as 1 or as many as all 7 can be specified.
What I've done is broken out these fields into Key,Value pairs for faster
searching. By keeping each searchable field as a seperate table ask the
Key and having the key field from the main file as the Value. I will then
return all matching values to the main search program.

My basic structure would be something like....

if parm1 <> '';
searchfield1()
endif;

if parm2 <> '';
searchfield2();
endif;

....

if parm7 <> '';
searchfield7();
endif;


Since each of these searches are on different files I want to be able to
do them in parallel to speed it up. Is there a way to do this without
doing a sbmjob. I can't do the sbmjob since I need to gather the results
of each searchfield procedure and then compile a master list.

Any idea will be appreciated.


Thanks
