File caching
The method of holding recently-used data in cache memory to enable quick
access to frequently requested files. NetWare Services uses the file caching
of the host operating system. In addition, it uses read-ahead cache.
See also: “Cache memory”; “Read-ahead cache.”
File compression
In NetWare 4, a means of allowing more data to be stored on server hard
disks by compressing (packing) files.
NetWare Services does not support file compression.
File handle
A number used to refer to or identify a file.
See also: “Handle.”
File locking
The means of ensuring that a file is updated correctly before another user,
application, or process can access the file. File locking physically locks a file
so that access by multiple users does not result in data being overwritten or
corrupted, or in the system locking up entirely.
For example, without file locking, if two users attempt to update the same
file simultaneously, one user could overwrite the file update of the other user.
Timeout values in most locking functions specify a maximum wait time for
a lock to be released before returning to the program.
See also “Record locking”; “Semaphore”; “Synchronization services.”
File rights
Rights that control what a trustee can do with a file.
See “Rights.”
