Chapter 1 The ADU Server
Cooperation of ADU Servers
When a new ADU Server is added to Avaya IC, existing ADU Servers must be made aware of the new server through use of the IC Manager. Refer to IC Administration Volume 1: Servers &
Domains for information on updating servers.
When the ADU Servers have been made aware of each other, they can make requests of each other. This is most significant in the area of the Assign method. When a client Assigns to an ADU Server, the Assign is relayed to other ADU Servers, and they watch for ADUs that match the client’s Assign criteria as well. This makes Assign a relatively expensive operation, and clients should be designed so they only need to Assign once to specify the ADUs in which they are interested. Assigning to multiple ADU Servers is unnecessary and causes numerous problems.
Every ADUID identifies the server that created it and the time at which it was created. When a client requests access to an ADU, the ADU Server that the client is using acts as a proxy to the originating ADU Server of the ADU.
