ADMINISTERING
Choosing the administration server for the Domino® Directory depends on your network setup, the available equipment, and the anticipated changes that will be made to the Domino Directory via the Administration Process.
Large numbers of name-management operations -- rename and delete requests for example -- result in many changes to the Domino Directory with the subsequent view rebuilding and thereby affecting performance. Making a heavily accessed server the administration server of the Domino Directory results in slow server performance from a user's perspective. Giving only one, or a few servers the responsibility of being the administration server of many databases may result in that server continually processing delete and name change requests. Choosing the administration server also involves planning how to assign administration servers for other databases in the domain because all name management operations require extensive searching of databases to determine which server is the administration server for the ACLs, Reader and Author fields, Name fields and unread lists. When choosing the administration server for databases in a domain, your choices include:
Option 2 -- A second option involves using a dedicated registration server as the administration server for the Domino Directory. You limit this server's responsibility to the processing of Domino Directory changes. You can then use other servers, such as database hubs, for processing ACL changes to other databases. To do so, specify the database hub as the administration server for those databases. You can divide the responsibility for database ACL changes among several administration servers; but, you must make sure that when there are multiple replicas of a database in the domain, you assign an administration server for only one replica.
Option 3 -- A third option involves using multiple servers to maintain the Domino Directory. If your domain is geographically dispersed, having a single administration server for the Domino Directory means all administration requests for Domino Directory changes have to replicate to this one server and the resultant changes have to replicate back. If your company is organized hierarchically, that is, it is composed of multiple organizations and organizational units, extended administration servers can be assigned to maintain the directory documents associated with people, groups, and servers whose names have that organization or organizational unit component.
