Configuration Files Used for the OSS Name Servers
If your system was ordered with the OSS environment preconfigured, then the OSS
Monitor was started at least once before you received the system. That action created
ZOSSFSET and might have embedded the factory-default node number in the
ALTFILE attributes.
After you change the node number, you must check that the OSS Monitor can open the
OSS fileset configuration database the next time the OSS Monitor is started. Enter the
following command at a TACL prompt after changing the node number:
FUP INFO ZOSSFSET,DETAIL
If output includes an ALTFILE name that looks something like:
\??.$SYSTEM.ZXOSSMON.ZOSSFS00
you need to correct the ALTFILE attributes. The question marks indicate that the
Guardian filename cannot be resolved because an unknown node number is
embedded. Because the filename cannot be resolved, the database cannot be opened
by the OSS Monitor at startup and the OSS file system cannot be restarted.
To fix the situation, enter the following commands at a TACL prompt:
VOLUME $SYSTEM.ZXOSSMON
FUP
ALTER ZOSSFSET, ALTFILE (0,ZOSSFS00)
ALTER ZOSSFSET, ALTFILE (1,ZOSSFS01)
EXIT
After these commands are executed, FUP INFO, DETAIL output does not contain
question marks because the Guardian file system is able to resolve the filename
correctly. Subsequent attempts to open ZOSSFSET succeed.
The ZOSSPARM File
The ZOSSPARM file is an Enscribe file that contains the subsystem configuration
database for the OSS Monitor. Entries in this file can be displayed by using the OSS
Monitor SCF INFO SUBSYS command.
This file must be maintained by the system manager using the OSS Monitor SCF
ALTER SUBSYS command. It must be present and must contain valid data before the
root fileset is first mounted.
Entries in the ZOSSPARM file must follow these rules:
•
Timeout values must be positive multiples of 1 second.
•
Any processor number specified must either be:
°
In the range 0 through 15
°
-1 (which specifies a process-dependent option)
Changes to the ZOSSPARM file take effect immediately.
