Yes, one of the services that STAF provides (with your typical STAF
install) is the Resource Pool (ResPool) service. The purpose of the
ResPool service is to manage exclusive access to the entries within
resource pools. For more information, see section "8.14 Resource Pool
(ResPool) Service" in the STAF User's Guide at
http://staf.sourceforge.net/current/STAFUG.htm#HDRRESSRV. I think the
ResPool service is what you're looking for.

Note that another STAF service that allows you to synchronize access to a
particular resource or to synchronize two or more tasks is the Semaphore
(SEM) service. The SEM service is one of the internal STAF services that
allows you to manipulate and manage two kinds of semaphores:
A mutex semaphore allows you to synchronize access to a particular
resource. You may request exclusive access of the semaphore, release
exclusive access of the semaphore, query the semaphore, and delete the
semaphore.
An event semaphore is a signaling mechanism used to synchronize two or
more tasks. You may post an event semaphore to signal that the event has
happened, reset an event semaphore in preparation for the next event,
pulse the event semaphore (which performs an atomic post and reset on the
semaphore), wait on an event semaphore, delete an event semaphore, and
query an event semaphore.
For more information, see section "8.15 Semaphore (SEM) Service" in the
STAF User's Guide at
http://staf.sourceforge.net/current/STAFUG.htm#HDRSEMSRV.

[staf-users] Possible Use For STAF/STAX?
Hi,
Right now, I'm using CruiseControl with selenium to drive a collection of
php-based browser tests.
There are numerous problems w/this setup. The biggest one is finding some
kind of resource control mechanism. That is, some way to allocate
resources as needed for tests from a common pool of resources.
For example, if I want to start a test which uses a windows-based browser,
I need to know if a windows machine is available. Its up the the *user* to
know that -- the harness has no dynamic knowledge of topology. This makes
parallel tests extremely difficult.
Is that possible with STAF/STAX?

Tks,
