Re: ILE RPG CGI and Activation Groups

["Jeffrey Flaker" <jflaker@xxxxxxx>]

I have recompiled programs and used them without restarting the server.
Only, my programs are using ACTGRP(*NEW), so this may be like comparing
apples and oranges.  Maybe this is another "advantage" of ACTGRP(*NEW)????
Maybe.

I don't know the exact details, but here is my take based on what I have
found.  

The *PGM object being called from the browser is holding onto an "instance"
of the *SRVPGM.  If the *SRVPGM is recompiled, the *PGM doesn't get the new
version until the *PGM object is also re-compiled or the instance is
restarted.  I run into this a lot with XML web services in RPG.

With that said I do not have a thorough understanding of how RPG objects are
stored in memory, and how/when they are replaced.  Anybody expound on that
subject?
