Changing the Operating Parameters of a Fileset
You change a fileset configuration when you enter new values for:
•
Automatic restart (DESIREDSTATE attribute)
•
Fileset recovery utility processor choice (FSCKCPU attribute)
•
Fileset recovery utility log file destination (REPORT attribute)
•
Fileset auditing (AUDITENABLED attribute)
•
Fileset buffering (the BUFFERED attribute)
•
Fileset storage-pool storage-pool file (POOL attribute)
•
Maximum number of files and directories (MAXINODES attribute)
•
User access restriction (the READONLY attribute)
•
Network File System (NFS) request timeout or cache (pool) size
•
Catalog file volume (CATALOG attribute)
•
OSS file system mount point (MNTPOINT attribute)
•
OSS name server identity (NAMESERVER attribute)
To change any of these attributes, use the following procedure:
1. Change the appropriate value in the ZOSSFSET file by using the SCF ALTER
FILESET command.
For example, entering the command:
ALTER FILESET $ZPMON.USER1, READONLY TRUE
causes all existing files in the fileset USER1 to be read-only. No new files can be
created in or written to the fileset USER1, and no existing files can be removed
from it.
Changes made to the DESIREDSTATE, FSCKCPU, and REPORT attributes take
effect immediately. Changes made to any other attribute require the following
additional steps.
•
To change any of the AUDITENABLED, BUFFERED, MAXINODES, POOL,
READONLY, or NFS attributes:
a. Apply the change to the fileset using the SCF CONTROL FILESET
Command with the SYNC option.
•
To change any of the CATALOG, MNTPOINT, or NAMESERVER attributes:
a. If the fileset is started, stop it by using the SCF STOP FILESET command,
as described under Stopping (Unmounting) a Fileset on page 5-13.
b. Restart the fileset using the SCF START FILESET Command.
All changes made to the fileset by an ALTER FILESET command take effect when the
fileset restarts.
