20.1.7.1.3. Connector/ODBC Performance
The Connector/ODBC driver has been optimized to provide very fast performance. If you experience
problems with the performance of Connector/ODBC, or notice a large amount of disk activity for simple
queries, there are a number of aspects to check:
• Ensure that
the tracing file by the ODBC Manager. You can check, and disable, tracing within Windows using the
Tracing panel of the ODBC Data Source Administrator. Within Mac OS X, check the Tracing panel of
ODBC Administrator. See
• Make sure you are using the standard version of the driver, and not the debug version. The debug
version includes additional checks and reporting measures.
• Disable the Connector/ODBC driver trace and query logs. These options are enabled for each DSN,
so make sure to examine only the DSN that you are using in your application. Within Windows, you
can disable the Connector/ODBC and query logs by modifying the DSN configuration. Within Mac
OS X and Unix, ensure that the driver trace (option value 4) and query logging (option value 524288)
are not enabled.
20.1.7.1.4. Setting ODBC Query Timeout in Windows
For more information on how to set the query timeout on Microsoft Windows when executing
queries through an ODBC connection, read the Microsoft knowledgebase document at

20.1.7.2. Connector/ODBC Application-Specific Tips
Most programs should work with Connector/ODBC, but for each of those listed here, there are specific
notes and tips to improve or enhance the way you work with Connector/ODBC and these applications.
With all applications, ensure that you are using the latest Connector/ODBC drivers, ODBC Manager
and any supporting libraries and interfaces used by your application. For example, on Windows, using
the latest version of Microsoft Data Access Components (MDAC) will improve the compatibility with
ODBC in general, and with the Connector/ODBC driver.
20.1.7.2.1. Using Connector/ODBC with Microsoft Applications
The majority of Microsoft applications have been tested with Connector/ODBC, including Microsoft
Office, Microsoft Access and the various programming languages supported within ASP and Microsoft
Visual Studio.
