Client/Server Processing
If both the client and its server maintain a transaction log of information necessary
for reestablishing a client session, client down time can be significantly reduced.
After the client reboots and logs in, the server can reestablish the session, provide
the status of client transactions, and continue processing transactions as necessary.
Tools
Table 11-2 lists Tandem software products that can help you develop and manage
client/server processing applications. For detailed descriptions of these products, refer to
Section 14, “Operations Management Tools.”

Product Function
Client Server Gateway
(CSG)
A workstation process that accepts service requests from
workstation applications through the CSG application
programming interface (API). Together with the SSG (see
below), it provides a general mechanism for delivering
commands from a workstation to command interpreters on a
Tandem host and returning responses to the workstation. The
DSM/NOW product uses Systems Support Group/Customer
Support Group (SSG/CSG) as its underlying mechanism for
exchanging commands and responses with host processes.
Data Access Language
(DAL) Server
Provides Macintosh users on attached LANs with reliable,
transparent, fault-tolerant, distributed access to data residing in
Tandem NonStop SQL/MP databases.
NonStop Access for
Networking
Extends fault-tolerant computing through the LAN to the
desktop.
NonStop ODBC Server Provides client applications with access to Tandem’s NonStop
SQL/MP relational database management system through the
Microsoft OPEN Database Connectivity (ODBC) interface.
NonStop Transaction
Services/MP (NonStop

developing and running client/server processing applications.
Pathway Open
Environment Toolkit
(POET)
A client/server product that works with the Remote Server Call
(RSC) product to enable programmers to create and run
client/server applications where the client is a Microsoft
Windows program and the server is a Pathway server running
on a Tandem NonStop system.
