Abstract

In the distributed computing environment, data and programs are replicated on servers across the network to increase the availability, reliability, and speed in accessing the information. Replicas are copies of specific data, stored at different physical locations. Disclosed is a method for viewing and manipulating cell directory service replicas in a graphical user interface.

Replicas View for the Cell Directory Service

       In the distributed computing environment, data and
programs are replicated on servers across the network to increase the
availability, reliability, and speed in accessing the information.
Replicas are copies of specific data, stored at different physical
locations.  Disclosed is a method for viewing and manipulating cell
directory service replicas in a graphical user interface.

      Replication is used in various components of the distributed
computing environment to improve performance and ensure availability
of data or programs across the network, particularly if one or more
nodes on the system are down. Replication is used specifically in the
cell directory service to maintain copies of directories at various
cell name servers.  Data is copied from the original location at a
given server to other servers in the network; the cell directory
service maintains information about where replicas are stored and
keeps the replicas synchronized when updates are made to the data.
The location and types of replicas can be managed by administrators
with the proper authority.

      Prior implementations use a command line interface to display
and manage directory replicas.  This method displays replicas in a
graphical user interface as a view of the directory from which they
originate, or as a view of the clearinghouses (databases) in which
the replicas are stored on a given server.  To navigate to this
information, the user selects the desired directory or clearinghouse
(which may be shown as icons in the graphical interface), then
chooses the "Replicas" view option from a menu; alternatively, the
user may open or double-click over the clearinghouse icon to reveal
the replicas view, since replica...
