Patrick,
I need a little more explaination on using the chooser option for load
balancing queues.
Prior to 3.6.18 the check_idle option was used in the sub queues. The
check idle processes for each sub queue ran util they detected a change
in status(busy->idle).
Now using the chooser option, the main queue gets a list of all its
sub queues and checks their status. I've got a chooser script that
checks
the Appsocket connections to my Phaser printers. (It essentially checks
for "idle" on UDP port 9101 and the ability to connect to TCP port 9100.
I had to do this since for my Tek 360s, connections are refused on 9100
even though 9101 says idle. This is an old problem reported on prior
postings.) If both checks are OK, my chooser exits with 0 and writes the
appropriate subqueue name to STDOUT.
Question #1:
Should the chooser run until it detects a free subqueue like check_idle
or
exit with an error if it can't find any available subqueues? (Mine runs
until it finds a free subqueue.)
Question #2:
How should I handle the error condition where I can't make a connection
or
get status from one remote printer, but another is available? As long as
at least one subqueue is available jobs will get sent, however, the
master
queue will never know there is a problem on one of its subqueues. Should
I
JABORT if I find a serious problem on any subqueue?
