Individual Delta servers are assigned to a Group in the server Preferences menu:
DeltaGUI tries to connect automatically to all servers in the network, but individual server groups can be blocked. This is done in the Configure > Preferences > Communication dialog to [Block Groups] so that DeltaGUI will refuse connections from certain groups.
Connect to a specific group on opening
From Delta 2.7, if, when you start DeltaGUI up, you know what group you want to address, hold Shift down as you open DeltaGUI. This will instead offer a selection dialog:
The drop-down list will show all 64 potential groups, and overrides any blocked server groups. Select the required group and DeltaGUI will open connected to that group. The Preferences > Communication > Blocked Groups option will be greyed out.
➢(See also Communication Configuration.)
View connected servers
You can view what servers are attempting to connect to this instance of DeltaGUI, by choosing the Help > Server Connections option from the DeltaGUI menu.
This example dialog shows 5 servers:
Three have mismatched server versions, but the server at 10.100.101.74 has been accepted as not blocked and is the correct version.
You can clear this list by pressing the Clear button – note that the list will now only show servers which attempt to connect from then on – previously connected servers will not show up.
Shown below is a graphical view of all blocked or active groups, with attached or blocked servers and the reason for blocking (blocked or mismatched versions):
Clicking on any of the groups will select that group in DeltaGUI.
If ‘Group’ flashes red
If you are using a group of servers, there should always be a Leader server with the others set to Follower.
If the Group flashes red (as below), there are other servers attached to the group which may not actually belong to it (i.e. not in a Leader/Follower configuration): individual and groups of servers should always be given their own group in the server software.
