[AG-TECH] Registry Peers

[Andrew A Rowley]

Hi,

I have now managed to successfully run my own bridge registry and registry peer under Linux and Windows.

To do this:
1) Create a text file that contains the IP address and port of the registry peer.  Put this text file on a web server so that it can be accessed by venue clients.  This web server is your bridge registry.

2) Locate the file RegistryPeer.py on your computer.  This is not usually in your AG bin directory, but is usually in your Python installation directory in site-packages/AccessGrid/Registry/RegistryPeer.py.

3) Windows Only: Add the following lines to the file before the line that reads "from AccessGrid.AGXMLRPCServer import AsyncAGXMLRPCServer"
    import agversion
    agversion.select(3)

4) Run:
       RegistryPeer.py -u <your-registry-url>
   where <your-registry-url> is the url set up in step 1.

5) Run your bridge(s) with the same -u option as above

6) Edit the AG client preferences file 
(Windows: c:\documents and settings\<username>\Application Data\AccessGrid3\Config\preferences; 
Linux: <home-dir>\.AccessGrid3\Config\preferences)
and change the line starting:
    bridgeServer = http://www.accessgrid.org/registry/peers.txt
to point to your registry url set up in step 1.

Now when you start the venue client, you should be using only your own bridge registry.

I am now working to add an option to the GUI preferences of the client to allow you to change the bridge registry url.  Hopefully, this change will appear in the next release of the AG toolkit.
