You have two different locations you log on to and wanted to know if you could have them both in the ATLAS SQL Alias Manager.
If you want to be able to log on to two different sites, you need to do the following:
1. Create a .dbc file for both sites but neither file can be named logon.dbc. Each file has to have a name other then logon.dbc.
When you want to change sites, you need to logoff the ILLiad Client and then go back to the ATLAS SQL Alias Manager and select the other site and click on the "Set Default" icon, then login to the illiad client.
