DirectConnect 12.6 and later has changed how it uses the Open Client and Open Server libraries. Although DirectConnect will continue to install the Open Client and Open Server libraries in the Sybase root directory (SYBASE/OCS-12_5), it will not use these libraries. Instead, it installs a copy of these libraries in the DirectConnect DC_12_6/lib, or the directory, which allows DirectConnect to isolate these libraries from Open Client and Open Server updates and from other Sybase products. This ensures that the DirectConnect libraries are the same version as the libraries used for certification. Updates to these libraries are made through the DirectConnect installation process.
