MX Release 3.2.1 (H06.26+, J06.15+)

1 Overview

The Linux ODBC/MX client driver (driver) implements the ODBC 3.5 set of APIs. The Linux ODBC

applications (applications) send the requests to access data from an SQL/MX database to this

driver. This chapter describes the following:

Architecture

The applications interact with the driver to access an SQL/MX database. The driver is thread-safe,

and you can write multi-threaded C/C++ applications, which use the POSIX thread library.

The driver architecture comprises of client and server components, as shown in the architectural

diagram.

The application calls the SQLConnect() ODBC API to open a connection to a data source

representing an SQL/MX database. The NonStop SQL/MX connectivity service (MXCS) provides

support for remote connections to the SQL/MX database, such as from ODBC applications. The
