Software fixes

Revised DirectConnect scripts

The DirectConnect scripts (DCStart, AddServer, DCDirector, DC_SYBASE) that are generated during installation have been simplified and improved. The scripts no longer rely on global shell environment variables; instead, they set environment variables based on the installation-generated file, DC_SYBASE.

WARNING! DirectConnect scripts use the DC_SYBASE script and not the SYBASE script.

The scripts and installation program have been changed to prevent environment variable overruns or truncation (CR 325317). Sybase strongly recommends that you use the scripts for DirectConnect operations to ensure a proper operating environment.Future versions of the DirectConnect installation program will not set global environment variables, and will require the use of supplied DirectConnect scripts for starting DirectConnect and DCDirector.

Express Transfer and ODBC option users: If you are using third-party ODBC drivers, including the ASE ODBC driver, you may need to modify the DC_SYBASE script to contain the library search path information required by the third-party ODBC driver.
