Operator Commands and the Supervisor Most HP Desk processes run under the control of the Supervisor. When you type any of the commands described in this section, a request is sent to the Supervisor to either start up or shut down the relevant process. Responses to a MAIL...ON Command Any MAIL...ON command starts up the Supervisor if it is not already running. If the Supervisor cannot log on, the JOBFENCE and LIMIT parameters for the system need checking. The values may need changing so that the Supervisor may log on. When the Supervisor acts on the start up request and the process has successfully started, a message appears on the Operator's console saying: HPDESK - process name created on date at time A message is sent for each process started up by a command. When the command is sent from a terminal other than the system console, a message is also sent to that terminal if possible. A delay may occur with error messages. You might find errors concerning a MAIL...ON command being reported some time after it appears to have completed successfully. If a MAIL...ON command is issued for a parameter which is already running or is starting, the Supervisor ignores it and no messages are displayed. Responses to a MAIL...OFF Command When the command is issued, the following message appears on the console and the issuing terminal: HPDESK - process name requested to stop on date at time If the command was issued at a terminal other than the operator console, the same message also appears on that terminal. When the process has actually stopped or up to 2 minutes afterwards, the following message appears on the operator console: HPDESK - process name stopped The amount of time between these two messages being displayed depends on the individual process and the amount of work it still has to process. For example, the Mailroom will not shut down until it has dealt with all outstanding messages. This may take half an hour on a busy system. If a MAIL...OFF command is issued for a process which is already shut down or stopping, the Supervisor ignores it and no message is displayed.
