Use the following procedure to verify that users are logged off of the system:
Log in to your current server as the Sybase System Administrator:
isql -Usa -Ppassword -Sserver_name
Enter:
1> sp_who
2> go
This command returns a list of all users and processes currently on the server.
Log off all users on the server.
The upgrade will not work if you boot the server in single-user mode.
