LockType — specify file locking method to use
The directive specifies the file locking method to use.
flock
is the default and works well with standard
setups.
fcntl
is used with NFS. In case of NFS, both
the NFS client and server need to run the lock daemon
(lockd).
none
can be used to turn off locking completely. This
is never recommended, unless you only want to see if the locking
is causing system hangs.
Although this directive was added in Interchange 4.7, due to an error later discovered, the directive started working properly with the release of Interchange 4.8.6.
If you are only accessing sessions on an NFS-mounted directory, but the rest
of Interchange is on the local filesystem, you can set the SessionType
directive to NFS
instead. That would enable
fcntl
locking for sessions on a per-catalog basis only.
