DICT Command
DICT Command
The DICT command instructs the DDL compiler to do the following:
•
Create and open an audited dictionary on a specified subvolume or open an
existing dictionary on a specified subvolume.
•
Enter all subsequent DDL object definitions into the open dictionary.
You can create a dictionary either by using the DICT command or by running the
Pathmaker application systems generator. When you add a Pathmaker project, the
Pathmaker software creates a DDL dictionary for you.
More than one user can write to a dictionary at the same time, whether the Pathmaker
tool or DDL created the dictionary.
DICT
creates and opens a new audited dictionary or opens an existing dictionary, and
enters all subsequent object definitions into the open dictionary. If a dictionary is
already open, the DICT command closes the current dictionary and opens the
specified dictionary.
dict-subvol-name
identifies the dictionary subvolume;
dict-subvol-name
is a subvolume name in
this form:
[\node-name.][$volume-name.][subvolume-name]
If
dict-subvol-name
is omitted, DDL uses the current system and the current
volume and subvolume. If
node-name
is omitted, DDL uses the current system; if
volume-name
is omitted, DDL uses the current volume; and if
subvolume-name
is omitted, DDL uses the current subvolume.
!
purges all existing dictionary files in the specified subvolume and creates a new
dictionary. DDL creates the new files using the extent sizes, MAXEXTENTS value,
security, and ownership associated with the purged dictionary. For example, if user
Y uses the DICT! command on a dictionary that belongs to user X, the resulting
dictionary still belongs to user X, still has the same number of extents in each file,
and still has the same security as the original dictionary; any other file
characteristics are those that might be expected from the creation of a completely
new dictionary by user Y. (User Y must have purge access to the original files to be
Note. DDL creates an audited dictionary only if the subvolume is audited. A dictionary on
a nonaudited subvolume is also nonaudited.
