Stopping Application, Devices, and Processes
•
Stopping DSM/SCM stops the CNFGINFO server process, the Pathway
environment for DSM/SCM, the alternate EMS collector $ZPHI, and TCP/IP
processes for DSM/SCM, as this example shows:
•
Following the SPOOLER DRAIN command, the collectors allow current jobs to
finish but reject new opens with a file-system error 66 (device downed). When you
drain the spooler, each collector stops when it has no more open jobs. Each print
process finishes printing any active jobs and then stops. After all collectors and
print processes have stopped, the supervisor stops. The spooler enters the
dormant state, ready to be warm started.
•
Following the SCF CONTROL, DISK REFRESH command, all other disk I/O is
suspended. The amount of time a refresh operation takes to finish depends on the
amount of disk cache containing dirty pages in use at the time, and writing to disk
can take several minutes.
Stop processes and applications in this order:
1. After you send a message alerting users of the shutdown, stop all user
applications.
2. If your system is equipped with Pathway, stop Pathway applications. At the
Pathway prompt:
= SHUTDOWN2, MODE ORDERLY
3. Stop Distributed Systems Management/Software Configuration Manager
(DSM/SCM) if it is running. At a TACL prompt:
a. Type this VOLUME command:
> VOLUME $DSMSCM.ZDSMSCM
b. Stop DSM/SCM:
> RUN STOPSCM
4. Stop communications lines, such as Expand lines.
5. Identify and stop any remaining processes that should be stopped individually:
a. Use the TACL PPD and STATUS commands to help you identify running
processes.
b. Use the TACL STOP command to stop running processes.
