Post Office Access Mode - Novell GROUPWISE 8 - ADMINISTRATION Administration Manual

Library Databases
The databases for managing libraries are stored in the
post office.
The
dmsh.db
where each library in the post office is located.
Each library has its own subdirectory in the gwdms directory. In each library directory, the
dmxxnn01-FF.db
what users have rights to access the library.
Document Storage Areas
The actual documents in a library are not kept in the library databases. They are kept in a document
storage area, which consists of a series of directories for storing document files. Documents are
encrypted and stored in BLOBs (binary large objects) to make document management easier. A
document, its versions, and related objects are stored together in the same BLOB.
A document storage area might be located in the post office directory structure, or in some other
location where more storage space is available. If it is located in the post office, the document
storage area can never be moved. Therefore, storing documents in the post office directory structure
is not usually recommended. If it is stored outside the post office, a document storage area can be
moved when additional disk space is required.

35.4 Post Office Access Mode

The GroupWise 6.x and later Windows client and the GroupWise 6.5 and later Linux/Mac client
both use client/server access mode to the post office. This requires a TCP/IP connection between the
GroupWise clients and the POA in order for users to access their mailboxes. Benefits of client/server
access include:
Load Balancing: The workload is split between the client workstation and the POA on another
server. The POA can perform a processor-intensive request while the client is doing something
else.
Database Integrity: The GroupWise client does not need write access to databases in the post
office. Therefore, client failures cannot damage databases.
Reduced Network Traffic: Requests are processed on the POA server and only the results are
sent back across the network to the client workstation.
Tighter Security: Client users do not need to log in to the server where the post office is
located. This eliminates the need for users to have write access to the post office directory.
Scalability: More concurrent users can be supported in a single post office.
Platform Independence: The GroupWise client on any platform can access the post office by
way of TCP/IP communication with the POA.
Simplified Client Connections: The GroupWise client can communicate with any POA in the
GroupWise system. Any POA can then redirect the client to connect to the correct POA for the
users' post office.
