Uninstalling ECDA

To uninstall an ECDA installation, use the installation program uninstall feature. This removes all servers, all common files, and all required components. After the uninstall runs, you may need to delete any remaining files and directories in the directory where ECDA was installed only if this is the only product installed.

Before uninstalling Sybase software, shut down all Sybase applications and processes.

You can invoke the uninstall procedure using either the GUI or the console method. Sybase recommends that you use the GUI method.

Log in to your machine using an account with “administrator” privileges, then shut down all other processes for the components you are uninstalling.

The installation program removes only those files that were loaded from the installation media. Some Sybase files, such as log and configuration files, are left intact for administrative purposes.
