Re: Call in ILERPG response time slow

["Steven Easton" <seaston@xxxxxxxxx>]

Thanks every one for your help

The machine is a model 600, with 40m of memory.  Test machine, No other
users signed on.  Was:
DFTACTGRP(*YES)
ACTGRP(QILE)
DBGVIEW(*ALL)
OPTIMIZE(*NONE)

I changed to:
DFTACTGRP(*no)
ACTGRP(QILE)
DBGVIEW(*source)
OPTIMIZE(*basic)

This dropped the response time to 9 seconds on the first call, and 7 second
on subsequent calls.

The extra overhead is in submitting compiles and making sure all programs
that use a module are recompiled when the module changes, and lastly
education.

remove the added overhead of creating an activation group each time you
call the subprogram. A word of warning though: Don't use ACTGRP(*CALLER) if
you're executing the program by calling it from an OPM program and using
bound calls. Results will be "unpredictable". If you need activation
groups, specify a named activation group. Do NOT use the default, which
creates a new activation group each time you call the program, and can
leave the old ones lying about. You could also look at the debug
information you're keeping in the program (DBGVIEW - check the docs). I'd
recommend using *SOURCE or *COPY, since that does not store the complete
source member in the program object. Also, OPTIMIZE(*BASIC) may help some,
with minimal risk of dysfunction.

to do is add the 'B'. If you build a binding directory and have a naming
convention, compiles are every bit as easy as PDM option 14 (I named mine
CP for compile).
