Use the LIBRARY DISABLE command to disable installation exit processing
for a particular system.
The following syntax is of the command to disable the installation
exit processing:
>>-+-LIBRARY-+--+-DISABLE-+--,--+-CBRUXENT-+-------------------><
'-LI------' '-DA------' '-CBRUXVNL-'
- DISABLE | DA
- Specifies a request to disable the installation exit.
- CBRUXENT
- Specifies a request to disable cartridge entry installation exit
processing. Cartridge entry processing does not occur on this system
while the exit is disabled.
Note: Disabling the cartridge entry installation
exit on a system allows cartridge entry to be processed by another
system, which is connected to the library and has the cartridge entry
exit enabled. In effect, this directs cartridge entry processing to
a particular system.
With APAR OA24966 (z/OS V1R8 and above), the
cartridge entry installation exit can be disabled prior to the start
of the OAM address space to ensure that when the OAM address space
is started, entry processing is not attempted on the disabled system.
- CBRUXVNL
- Specifies a request to disable volume not in library installation
exit processing.
Note: This does not disable job processing but does
result in the volume not in library installation exit being bypassed
or not called. In the absence of the CBRUXVNL installation exit's
intervention, Job Step Setup processing attempts to allocate an applicable
stand-alone tape drive for a volume that has been inadvertently ejected
from a tape library. If there is no stand-alone drive capable of handling
the tape volume request, the job or dynamic allocation fails. During
Device Allocation or during Library Mount Processing, normal job processing
for a volume not in the library with no CBRUXVNL installation exit
intervention causes the failure of the job step or dynamic allocation.
The following message displays upon successful completion of the
disable request:
CBR1951I Installation exit installation-exit-name has been disabled by operator command.
The installation exit processing on this system is disabled until
a LIBRARY RESET command is issued or the system is IPLed. Restarting
the OAM address space does not re-enable installation exit processing
if it has been disabled by an operator command. You can use the DISPLAY
SMS,OAM command to display the current status of the installation
exits.
