NAME
nfs3_do_readdirplus — turn on or off NFS version 3 readdirplus functionality on the NFS server
VALUES
Allowed values
0: turn off NFS version 3 readdirplus functionality
1: turn on NFS version 3 readdirplus functionality
DESCRIPTION
nfs3_do_readdirplus
controls the ability to turn on or off the NFS version 3 readdirplus
functionality on the NFS server. If this functionality is turned off,
the client is forced to use the readdir functionality instead.
Who Is Expected to Change This Tunable?
The distributed file system administrator should examine this value if
performance issues are being experienced when reading large directories.
Restrictions on Changing
The
nfs3_do_readdirplus
tunable is dynamic; tuning will take effect immediately on the running system.
What Are the Side Effects of Turning Off the Readdirplus Functionality?
By forcing the client to use readdir instead of readdirplus, the client is
no longer following the NFS version 3 protocol. If problems occur, turn
nfs3_do_readdirplus
back on.
WARNINGS
All HP-UX kernel tunable parameters are release specific.
This parameter may be removed or have its meaning changed in
future releases of HP-UX.
Installation of optional kernel software, from HP or other vendors,
may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or
recommended values. For information about the effects of
installation on tunable values, consult the documentation
for the kernel software being installed.
For information about optional kernel software that was
factory installed on your system, see
