Last updated on JULY 05, 2017

Applies to:

Oracle ODBC Driver - Version: 9.2.0.1.0 to 11.2.0.1 - Release: to 11.2
Microsoft Windows (32-bit)

Symptoms

Applications that repeatedly load and unload the Oracle ODBC driver (sqora32.dll) may experience a memory leak.  

This condition can be much more obvious in applications that do not take advantage of connection pooling, and instead open a hard connection every time.
