U.S. Coast Guard Common Operating Environment (USCG COE)
Appendix 3 - Workstation/Server Architecture
Overview: The following information represents some general concepts behind the Coast Guard's
NT Workstation/Server Architecture implementation, which should help developers "target" their
applications for the U.S. Coast Guard standard workstation environment.
Application Code Location: In the U.S. Coast Guard standard workstation client-server
environment what goes on the client is, by and large, already there. Items that go on the desktop
(laptop) workstation include:
- the operating system
- MS Office suite
- Mail Client (Exchange/Outlook)
- Dr. Solomon's anti-virus toolkit and WinGuard
- Internet Browser
With few exceptions, nothing else is allowed on the client:
Exceptions include .DLL or other similar types of files that, for whatever reason, cannot work
correctly from the Server; registry settings for specific applications; initialization or configuration
files specific to an application.
NO executables are allowed on the workstation.
NO permanent data files are allowed on the workstation.
TEMPORARY "scratch" space for applications, to which users have full read/write/delete access,
is provided in the C:\TEMP directory. This is temporary file space and is deleted upon each
logon/logoff of the user.
All users have several default network drives mapped during user logon by virtue of a
logon.cmd script. These drive/directory locations are:
H:\ -- the Apps share on the Application Server.
O:\ -- the NetApps share on the Application Server.
U:\ -- the user's personal file share on their specific File Server.
The H:\ and U:\ drive mappings are part of the original NT3.51 system
configuration/architecture. The O:\ drive mapping is a new addition due to NT4.0 and Zero Admin
Kit considerations.
Applications should be written to a specific (developer-defined, TISCOM approved)
subdirectory under either the Apps or NetApps share on the Application Server.
ORACLE code location The current SWIII configuration has the runtime files for ORACLE
Forms, Reports and both SQL*Net and Net8.
These are located in the BIN subdirectory of the Apps share (H:\ drive).
