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.

Subject: Re: [WEB400] ILE RPG CGI and Activation Groups

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?

Thanks Scott, from another perspective on this, if I wanted to be
able to recompile the app for some logic changes in the middle of the
day, and that app was in a named activation group and was loaded, the
new version would not be used for that activation until the HTTP
server was shutdown. Any new activation group would load the new
version. Do I have this right? The same as in the old model if LR was
left OFF on a RETURN. That user keeps using the old application
version and new users would get the new version. Difference in CGI
world being that a user is the HTTP subsystem job, which could be
servicing many many browser requests, not the browser user making the
request. And in CGI world since there are multiple CGI jobs in the
HTTP subsystem one request from "user A" could hit the old versions
of the app and the next request from "user A" could hit the new
version of the app (assuming no persistence is setup).
