Re: large difference in job run times between bound procedure call, and procedure call from within program.

Also, another point of reference. Error handling is extremely important in
SQL. For a Select statement you need a minimum of the following:

Select;
When SqlState = SQL_STATE_NO_ROW; // My constant meaning '02000''
//actions to take when nothing returned.
When SqlState = SQL_STATE_OK; // My constant for '00000'
// Actions if Ok read
Other;
// Error handling. Very important you have a method of logging and
reporting errors.
// I have an error logging system that logs the error and sends notice
that it happened.
// Extremely important to not ignore SQL Errors.
EndSl;

here is my 2 cents:

* do not turn on LR in the procedure, have an initialization logic
that is processed only at the first call
* make sure your utility program is not using *NEW activation group.

------------------------------

I don't have my terms correct, sorry.

we have many programs that have a sub-routine, called "get allocations".
This routine is found in over a dozen of our programs, and trying to
simplify things, I made it a
procedure, and even migrated from f specs to complete SQL.

However, in a program that invokes this routine 300k times, the run time
went from 25 seconds, to
350 seconds to sometimes over 400 seconds.

If I put the procedure in the bottom of the program I call it, it runs as
fast as the sub-routine call.

maybe this is normal for the overhead of having a bound procedure call,

or

maybe I just don't know what i need to do.
