Hi Chris,
Here's how we configure our UI at Glasgow to use multiple WMSs.
svr020:~# cat /opt/glite/etc/atlas/glite_wmsui.conf
[
VirtualOrganisation = "atlas";
MyProxyServer = "lcgrbp01.gridpp.rl.ac.uk";
HLRLocation = "";
NSAddresses = {"svr022.gla.scotgrid.ac.uk","svr023.gla.scotgrid.ac.uk"};
LBAddresses = {{"svr022.gla.scotgrid.ac.uk","svr023.gla.scotgrid.ac.uk"}};
]
svr020:~# cat /opt/glite/etc/atlas/glite_wms.conf
<snip>
WMProxyEndpoints =
{"https://svr022.gla.scotgrid.ac.uk:7443/glite_wms_wmproxy_server","https://svr023.gla.scotgrid.ac.uk:7443/glite_wms_wmproxy_server"};
So, to answer your question, I think you'll need to change both
glite_wms.conf and glite_wmsui.conf.
We're currently investigating how the (1 day?) myproxy outage will be managed.
Cheers,
Mike.
