Discussion on CDS Namespace management.

EDS use of CDS
applications are departmental based (finance vs. Engineering) or Organizational
/.:/profile/users/jsmith01 has users profile
/.:/profile/dept/CPS directory created for application CPS to use as they wish.
/.:/hosts/earth/CPS/svr contains server entries which get exported to
/.:/profile/dept/CPS/finance and to /.:/profile/users/jsmith01

Central administrator creates /.:/profile/CPS, application group makes changes below this as

OEC Recommended namespace usage is quite similar, uses /.:/applications/services vs. /.:/profile.

CITI has /.:/apps/[demos tools sandbox] format.

EDS uses normal Unix backup procedures and has had to restore CDS.
And it worked. CITI tried to use CDS replication and it failed so it is not
used now. Ford has replicated CDS between DCE and HP successfully.
EDS replicates extensively to physically separate servers. Key seemed to be
correct sequence of steps.

Big thank you to CITI for providing the facilities (and the coffee).
