extent-spec
is the size of the file extents allocated to the file. Specify either of these:
EXT [ ( ] pri-extent-size [ )
EXT ( [ pri-extent-size ] , sec-extent-size )
pri-extent-size
is the size of the primary file extent to be allocated to the file. It is an
integer in the range from 1 through 65535. (For treatment of pri-
extent-size by applications written in other languages, see the
appropriate language manual.)
sec-extent-size
is the size of the secondary extents, allocated to the file after the primary
extent is allocated. It is an integer in the range from 1 through 65535. (For
details on treatment of sec-extent-size by applications written in other
languages, see the appropriate language manual.)
exclusion-spec
is the exclusion mode for logical-unit. It determines the circumstances under
which other processes can access the file. Specify exclusion-spec as one
of these:
EXCLUSIVE
SHARED
PROTECTED
EXCLUSIVE
means that no other processes can access actual-file-name while the
program that refers to logical-unit has the file open.
SHARED
means that other processes can both read and write to actual-file-
name while the program that refers to logical-unit has the file open.
PROTECTED
means that another process can read, but not write to, actual-file-
name while the program that refers to logical-unit has the file open.
