The acurcl -alias command starts the server alias file manager utility. This utility is used to create and maintain the alias file required on the server for thin client operations only. This file holds all the information that is needed to invoke the appropriate runtime on the server. To use -alias on a UNIX server, you must be logged in as root or superuser. On a Windows server, you must use -alias from the administrator account or from an account that belongs to the administrators group. See Creating a Server Alias File in Thin Client for a description of how to use this utility.
