ALTER FILESET Command
The pathname described in MNTPOINT must be an existing directory, but the OSS
Monitor does not validate this until an attempt is made to start the fileset. Do not
include symbolic links in mount-point pathname specifications. Normalization of
pathnames for mount points does not include resolution of symbolic links.
If the MNTPOINT option is omitted, the mount-point directory for the fileset is not
changed.
NAMESERVER servername
specifies the server name of the OSS name server that should administer the
fileset. Only names currently defined in the ZOSSSERV file are valid values.
The first character of the name must be a pound sign (#). Server names are not
case-sensitive.
If the NAMESERVER option is omitted, the OSS name server process for the
fileset is not changed.
NFSPOOL kbytes
specifies the number of kilobytes that the OSS name server uses for buffers for
nonretryable Network File System (NFS) operations for the fileset.
Valid values are in the range 4 through 128 kilobytes.
If the NFSPOOL option is omitted, the number of kilobytes that the OSS name
server uses for buffers is not changed.
NFSTIMEOUT seconds
specifies the number of seconds that the OSS name server retains the results of
nonretryable Network File System (NFS) operations for the fileset.
Valid values are in the range 60 through 300.
If the NFSTIMEOUT option is omitted, the timeout interval for the fileset is not
changed.
NORMALIOMODE { UNBUFFEREDCP | DP2BUFFEREDCP | OSSBUFFEREDCP |
DP2BUFFERED | OSSBUFFERED }
specifies the input/output buffering and fault tolerance for application file opens that
do not use the O_SYNC option:
UNBUFFEREDCP Use unbuffered input/output with checkpointing. This
behavior provides maximum fault tolerance but with
reduced performance.
