STOPOSS Utility
•
Fileset mount points should be checked after all filesets are started to ensure that
they have security permissions consistent with your site’s security policies. The
OSS shell chmod command can be used to modify permissions as necessary.
STOPOSS Utility
The STOPOSS utility stops all filesets, regardless of whether they were configured in
OSSINF or OSSINFIL. STOPOSS is intended for use before a system shutdown. It
does not stop OSS servers (such as $ZPLS or $ZMSGQ) or subsystem processes,
because that action is not needed before a system shutdown.
Command
To run STOPOSS, enter these commands:
Considerations
•
Beginning with the G06.17 release version update (RVU) and the G10 version of
the OSS Monitor, the OSS Monitor no longer uses the $NULL process or requires
the $ZSMP process for its own startup. However, stopping $NULL or $ZSMP could
affect the functioning of other products or subsystems.
•
If $ZSMP, $NULL, or $ZPMON are not running when the T0585AAA version of
STOPOSS is run, STOPOSS starts the missing process so that it can complete its
function, then stops the process again before completing.
•
If $ZSMP and/or $NULL are specified in the EASYSETUP^STARTUP PARAM and
are not running, or if $ZPMON is not running when the T0585AAB version of
STOPOSS is run, STOPOSS starts the missing process so that it can complete its
function, then stops the process again before completing.
If you used OSSSETUP to configure $ZSMP or you manually configured $ZSMP
as a generic process using the recommended values defined in Starting the OSS
Monitor as a Persistent Process on page 2-9, $ZSMP will not restart itself because
its AUTORESTART value is 0. If $ZSMP does not have an AUTORESTART value
of 0, you must use the SCF ABORT command and then the SAFECOM STOP
command to permanently stop $ZSMP.
•
The STOPOSS utility, the files it accesses, and the processes it stops must be
appropriately secured for access by users other than the super ID, according to
your site’s security guidelines. See Licensing the OSS Monitor to the Super Group
on page 8-20 for a possible approach.
•
You must be logged in as a member of the super group (255,nnn) to use this utility.
•
You cannot use this command from a remote Expand node.
