Verifying server status

You can verify the status of your servers with these methods:

If a login fails, it may be caused by one of the following problems:

Problem: You typed an incorrect name, or the interfaces file you are using does not have an entry for the server.

DB-LIBRARY error:
  Server name not found in interface file.

Problem: The server is running, but you specified an incorrect login name or password.

DB-LIBRARY error:
  Login incorrect.

Problem: The server is not running.

Operating-system error:
  Invalid argument
 DB-LIBRARY error:
  Unable to connect: Server is unavailable
  or does not exist.

Problem: The interfaces file cannot be found.

Operating-system error:
  No such file or directory
 DB-LIBRARY error:
  Could not open interface file.

Problem: The interfaces file exists, but you do not have permission to access it.

Operating-system error:
  Permission denied
 DB-LIBRARY error:
   Could not open interface file

If you can not log in but do not receive a error message, you can assume that the server has stopped processing. Call Sybase Technical Support if you need assistance in determining the problem.
