Client-Library and Server-Library support dynamic loading of directory and security drivers. This allows you to change a driver that an application uses and to use features as they become available at your site, without re-linking the application.
$SYBASE/$SYBASE_OCS/config/libtcl.cfg configures directory and security drivers. This file maps symbolic strings to the appropriate driver and any required initialization information.
Client-Library or Server-Library applications, including Sybase utility programs such as dscp, locate the appropriate drivers specified in libtcl.cfg as follows:
If the driver file name in libtcl.cfg has path components (contains a slash), that path is used. Otherwise, the search continues to step 2.
Depending on your platform, the directories specified by these environment variables are searched. If the driver is not located, the search continues to step 3.
The library locations and environment variables are listed in Table 5-5.
The path $SYBASE/$SYBASE_OCS/lib is used (or $SYBASE/$SYBASE_OCS/devlib for applications built with debug-mode libraries).
