Managing SNAplus2 from NetView
Using UCF
If you issue a command when a previous command is still in progress
(that is, before the UNIX COMMAND COMPLETED message is received), the
following message is displayed:
= = = COMMAND QUEUED = = =
The second command is queued, and is executed when the previous
command has completed.
Canceling a Command
UCF provides a method of canceling a command that is still in progress.
This can be used to stop the current command from executing, or to
cancel an interactive command such as vi filename that cannot
complete without further input. It is equivalent to using an interrupt
sequence such as Ctrl + C to stop a process running on a terminal, or using
the HP-UX kill command to stop the process.
In addition to canceling the command that is currently executing,
SNAplus2 cancels any commands that are queued after it.
The command syntax is the same as for the HP-UX command, with the
string ux-cancel instead of the command text. For example:
runcmd sp=myspname, appl=unix, ux-cancel
For each outstanding command (the one currently executing and any
queued commands), the following message is displayed:
= = = UNIX COMMAND CANCELLED = = =
This message indicates that the HP-UX shell in which the command was
running has been stopped. Further HP-UX commands can be issued as
necessary.
If a command starts a daemon process on the HP-UX computer, this
process may not be stopped by ux-cancel. You may need to use the
HP-UX kill command (either on a terminal or by using UCF) to stop
such a process explicitly.
If no UCF command is running when ux-cancel is used, UCF displays
the following message:
NO OUTSTANDING COMMANDS
