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.The DirectConnect installation program no longer sets global environment variables, and requires the use of supplied DirectConnect scripts for starting DirectConnect and DCDirector. To avoid common environmental setup problems, Sybase strongly recommends using DirectConnect scripts.
