Re: Multiple Jobs reading from same data queue-who's turn is it?

[Dave Murvin <davem@xxxxxxxx>]

Thanks Eric,

Although I do not think our requirements are that dynamic (we plan to go 
live this weekend using 6 server programs to start), I had not thought 
of monitoring the data queue for a back log of requests to automatically 
add more server programs.  What do you see the monitoring program 
looking like?  Would you use and API to retrieve the data queue 
description (and thus the number or entries) or what?  Would the 
monitoring program just wake up every n number of minutes and check?   
We can always use the telephone - when the users complain we can add 
more server programs. :-)

Thanks

Dave
