Re: system event trigger whenever a source file member is updated

Syd:

Seems unusual that the sending site controls the names, but there always seems 
to be restrictions whatever we do. (In the extreme, what if they chose library 
QSYS and file name QADBIFLD? :-) )

Okay, does the file have to exist ahead of time? I mean, I realize that a 
pre-existing file can have advantages in terms of field definitions, etc.; but 
you'll have better luck with the audit journal if you trigger on the file 
create than if you try to trigger on member. As soon as you can lock the file 
*EXCL after creation, you could rename it. That lets you work with the data 
while making the reserved file name available once again.

But I'm not sure any kind of audit journal monitor is going to be appreciably 
faster or more efficient than a basic NEP that periodically (every 10 seconds? 
60 secs? 300?) wakes up and lists the members in the target file and hands them 
off for processing. If all it needs is to check the list of members, it won't 
be much of a resource user... until there's actually a new member to process of 
course.
