RE: [Queue-developers] manage a tool license as a resource?

[Werner K. <wk...@sd...>]

A subset of TI, Alantro, developed a module for GQ that was intended,
ultimately, to be used with a license manager.

This is the queue_manager package, which can be turned on in ./configure
(./configure --enable_manager=YES)

This sets up a centralized server than monitors the Queue demons cluster
wide via an SQL server (there are free ones---Postgresql comes to mind---
as well as another famous SQL server that's not quite free.)

The queue_manager monitors the number of a particular that is running,
and can enforce limits on that.

Alantro's idea was to GQ together with their monitoring software to ensure
that licensed programs were registered with GQ, could only be run in a
monitored queue, and thus basically used GQ as a license manager.

They were worried about the political ramifications of use a GNU program
for license management, since that implies non-free software. However, I
persuaded them that the GNU community would certainly welcome a central
protocol that enforced other limits as well (eg resource limits) and
that's what queue_manager does.

The docs are in doc/queue_manager .
