1 ODBC/MX Client Overview

Applications developed for the Microsoft® Open Database Connectivity (ODBC)

application programming interface (API) can use SQL/MX to access a NonStop SQL

database on an HP NonStop server, through HP NonStop SQL/MX connectivity

services (MXCS).

Client Components

Client components are installed on any workstation running Microsoft Windows 98,

Windows NT 4, Windows 2000, Windows 2000 Server, Windows 2003 Server, or

Windows XP.

•

ODBC client application: A user-written application or third-party product that uses

the ODBC API to access data.

•

Microsoft ODBC 3.51 (or later) driver manager: Manages access to ODBC drivers

for applications. The driver manager loads and unloads drivers and passes calls

for ODBC functions to the correct driver.

•

ODBC/MX driver: Implements ODBC function calls (a subset of the ODBC 3.5.1

API), which allow an ODBC client application to access a NonStop SQL database

through the MXCS service.

•

The Microsoft ODBC Data Source Administrator.

Data Sources

To configure ODBC client access to SQL/MX (which accesses NonStop SQL

databases), MXCS requires data source definitions on both the NonStop server and

the client workstation.

Default Data Source

MXCS provides a preconfigured, default server data source on the server called

TDM_Default_DataSource. You can stop and start the TDM_Default_DataSource
