Commands
NSCONTROL ABORT
NSCONTROL ABORT
Immediately terminates all the servers and services of the Network
Services.
Syntax
NSCONTROL ABORT
Parameters
ABORT Immediately terminates all NS servers and services
without allowing existing processes to run to
completion. Useful in cases where you need to
terminate Network Services immediately regardless of
whether or not existing processes terminate normally.
Note that STOP is the normal way to shutdown Network
Services.
Discussion
There are two NSCONTROL functions that you can use to terminate the
Network Services. Before using either method, be sure to warn all users
that their network services are about to be closed.
• NSCONTROL STOP allows existing users to continue using the services
until they finish their tasks and prevents any new users from using
the services. Using NSCONTROL STOP is the recommended way to
terminate the Network Services. It allows the services to terminate
gracefully.
• NSCONTROL ABORT immediately terminates all the services and all
the server processes. Use NSCONTROL ABORT only when you don't
care about letting existing processes run to completion. Anyone
using a service finds their task (REMOTE, DSCOPY, and so forth)
immediately terminated.
HP recommends that you use the sequence of NSCONTROL STOP followed
by NSCONTROL ABORT to ensure that you terminate all Network
Services. Special situations where this may be appropriate include
when the system is being prepared for software installation, or when
the system needs to be taken down for maintenance. Abnormal
situations can occur when an application has been incorrectly
implemented. If you cannot terminate the session by any other method,
use NSCONTROL ABORT to terminate all Network Services. This will clear
any problems. The sequence to use prior to issuing the NSCONTROL
ABORT command is shown in example 1; an abnormal situation is
described in example 2.
