[AG-TECH] RH7.2 AG2.0 problem

[Todd Zimmerman]

Hi all,

I'm trying to get our room node working under AG2.0 and am having a few
issues with the Linux side.  The Windows side seems to be working fine.
I've tried to run the Linux side as either a stand-alone node or as part of
the room node - but can't get it working either way.


When trying to run the Linux box in stand-alone mode:

I've basically followed the instructions at
http://hpcnc.cpe.ku.ac.th/moin/InstallingAccessGrid to try to get the node
running.  

All seems to work fine.  I start the AGNodeService and the AGServiceManager &
start the VenueClient.  Once up and running, I can start the Node Manager and
add the serviceManager & services, save the setup etc and connect to the
VenueServer.  Again, at this point, all is still well.  However, when I
attempt to change rooms the VenueClient hangs with the following output in
the debug window:

>From there it hangs and I have to manually go in and kill the processes.  


Now, when attempting to run the node as part of the room node, I get a
different error; however, I'm sure they are interrelated.  On the Linux box,
I start up the AGServiceManager.py and start the NodeService and
ServiceManager on the Windows side.  Once within the NodeManager I add the
Linuxbox ServiceManager to the list (all ok so far) and start adding
VideoProducer services.  It actually finds the three capture cards on the
Linux box; however, when it adds them, it complains:

Exception in AddService :  AccessGrid.hosting.pyGlobus.AGGSISOAP.faultType
<Fault exceptions.AttributeError: AttributeError: 'str' object has no
attribute 'uri'

And on the Linux side AGServiceManager debug prints out (with our
computername removed....):
-----------------------------------------------------------------------------
------------------------
Running Service; options: /usr/bin/python2.2
['/tmp/local_services/VideoProducerService.py', 60348]

    while server.IsRunning():
AttributeError: Server instance has no attribute 'IsRunning'
Trying client handle 
* * Service handle is valid ! 
-----------------------------------------------------------------------------
----------------------------


I'm sure these two issues are related - and I'm wondering if it is
conflicting with a pre RC install of AG2.0 - I thought I had removed all
remnents but one can never be sure.

Any help would be appreciated!!!


Thanks in advance,
