nfs_fine_grain_fs_lock
Enabling this tunable reduces the occurrence of alpha semaphore contention in NFS file
operations that are performed serially. This tunable will be obsolete in a future release.
nfs_new_lock_code
Controls the performance of asynchronous I/O against files that are locked on NFS filesys-
tems. This tunable will be obsolete in a future release.
nfs_new_rnode_lock_code
Allows the threads that are waiting for an rnode lock to sleep interruptibly or noninterrup-
tibly. This tunable will be obsolete in a future release.
nfs_posix_pathconf_chown
Controls whether or not the function calls pathconf and fpathconf conform to POSIX stan-
dard when called over NFS filesystems. This tunable will be obsolete in a future release.
nfs_wakeup_one
Enables you to specify whether the NFS client must activate all NFS threads or only a sin-
gle NFS thread waiting for the same rnode lock. It also enables you to specify whether the
NFS client must activate all sleeping biods or only a single sleeping biod while servicing a
new request. This tunable will be obsolete in a future release.
nfs3_hacc_size
Allows you to specify the number of hash buckets to be used by the NFS v3 access cache.
This tunable will be obsolete in a future release.
nfs3_new_acache
Allows you to specify which search algorithm (linear or hashed) to use to find an entry in
the access cache. This tunable will be obsolete in a future release.
nfs_portmon
Used to enable or disable the check to verify that the source port is a reserved port.
nfs_exportfs_rwlock
Allows you to use either hashed exclusive spinlocks or hashed reader/writer spinlocks to
protect the exportfs table. This tunable will be obsolete in a future release.
nfs_srv_read_copy_avoid
An unnecessary copy of data to XDR buffers impacts the read performance of NFS. Ena-
bling this tunable avoids this copy and may improve the read performance of NFS. This
tunable will be obsolete in a future release.
nfs3_adaptive_cache_validate
Used to enable or disable write WCC (weak cache consistency) check when a write is fol-
lowed by a read. Also, check for cache and invalidate the same in case of read before write.
This tunable will be obsolete in a future release.
The setoncenv command recognizes the following configuration variable names for the NIS subsystem:
MAX_NISCHECKS [number]
The maximum number of times the NIS client should attempt to contact an NIS server
before failing. This variable is used during system startup.
NIS_CLIENT [0 | 1]
Used to enable or disable the NIS client during system startup. Can either be 0 to disable
or 1 to enable the service.
NIS_DOMAIN [domain_string]
Used to set the domain name by /sbin/init.d/nis.server and
/sbin/init.d/nis.client.
NIS_MASTER_SERVER [0 | 1]
Used to enable or disable the NIS Master Server by /sbin/init.d/nis.server
.
Can either be 0 to disable or 1 to enable the service.
NIS_SLAVE_SERVER [0 | 1]
Used to enable or disable the NIS Slave Server by /sbin/init.d/nis.server. Can
either be 0 to disable or 1 to enable the service.
YPBIND_OPTIONS [option_string]
The run time arguments for the ypbind daemon used by
