Informix Error -468

-468 Cannot obtain the user ID from the system. Unable to start the database server.

Your application is trying to open communications to a database server. As part of this action, it has to read your user ID from the system password file, and it failed to do this. Look for operating-system error messages that might give more specific information. Consult with a system administrator to ensure that the file of user IDs is readable to all users.
