Steps for shutting down z/OS UNIX using F BPXOINIT,SHUTDOWN=...
About this task
Before you begin: You need to notify users
that the system is being shut down and ask them to log off. If you
do not shut down and quiesce the UNIX workload,
these critical system functions might be ended abnormally during the
shutdown, which might cause several failures on the system. As a result,
the system might not be shut down successfully.
- Use the operator SEND command to send a note to all TSO/E users
telling them that the system will be shut down at a certain time.
For example:
send 'The system is being shut down in five minutes. Log off.',NOW
- Use the wall command to send a similar note
about the impending shutdown to all shell users who are logged on.
For example:
wall The system is being shut down in five minutes. Please log off.
Perform the following steps to shut down z/OS UNIX using F BPXOINIT,SHUTDOWN.
Procedure
Results
When you are done, you have ended all of the processes.
You can do any of the following:
- IPL
- Power® off
- Take down JES, restart JES, and then rebuild your environment.
For example:
- Remount any file systems that you unmounted. To do all the mounts, you must issue mount commands or construct a REXX exec or CLIST. If you are using automount for user file systems, there will be less work involved.
- If you terminated the address spaces for TCP/IP and DFSS, you must restart these.
- If you terminated daemons, log on to TSO as superuser and run /etc/rc from a shell or from the ISHELL.
- Notify users that the system is once again available for UNIX processing.
