Client Trace 2
The OpenLink client component configuration utility, located in the
OpenLink group on your Windows desktop, allows you to enable or
disable ODBC trace logging. Trace logging provides you with output on
your entire ODBC session, including all ODBC calls made by the ODBC-
compliant application you are using. See the “
Administer ODBC Options”
section in this chapter for complete information on this utility. This file also
includes native database error messages that might not have been
replaced by the ODBC-compliant application you were using.
