Abstract

The lightweight Cell Directory Service (CDS) stores CDS objects in a simple ASCII text file. If a network does not have shared file capability, how can the directory information stored on a CDS server machine be accessed across a network? This invention solves the problem by creating a server lightweight CDS daemon, and an RPC (Remote Procedure Call) interface is used to access the namespace information rather than a shared file.

This text was extracted from an ASCII text file.

Lightweight Cell Directory Service Daemon

      The lightweight Cell Directory Service (CDS) stores CDS objects
in a simple ASCII text file.  If a network does not have shared file
capability, how can the directory information stored on a CDS server
machine be accessed across a network?  This invention solves the
problem by creating a server lightweight CDS daemon, and an RPC
(Remote Procedure Call) interface is used to access the namespace
information rather than a shared file.

      A lightweight version of CDS can be achieved by storing its
data in a simple text file.  This text file can be shared via LAN
Server, Netware, nfs mounts, or any file sharing system.  However, if
a network does not have shared file capability, how can the directory
information stored on a CDS server machine be accessed across a
newtork?

      Our invention is to create a lightweight CDS daemon to handle
the name service request, and create a lightweight CDS client
services to make RPC calls to the daemon.  The text file for storing
the CDS objects then can reside on the daemon machine which can be
managed by the server's security service or physically secured.

      In this invention, the file is maintained solely by the
lightweight CDS server, allowing the file format to change without
affecting the lightweight CDS clients.  The interface between the CDS
server and CDS client is defined in a Interface Definition Language
(IDL) file.  This file is compiled to produce...
