Use the COPY command to copy portions of the directory hierarchy and
their related data definitions from one area of the CDD to another.
With the COPY command, you specify the dictionary directories,
subdictionaries, and objects you want copied, and you specify the
dictionary directory or subdictionary to which you want the copy
appended. In addition to portions of the directory hierarchy, you
can copy history and access control lists. You can also create a log
of the given names of each copied dictionary directory,
subdictionary, and object.
Command Syntax:
COPY [qualifiers] source-path-name [,source-path-name]...
destination-path-name
1 – parameters
source-path-name Identifies the source of the copy. You can use the wildcards % and * in the last given name of the source path name, and you can use > or .> at the end of the chain. You cannot use @. If you are using a terminal of the VT200 family, you can use 8-bit characters in path names. DMU assumes a > at the end of the chain by default. Type "HELP specify path-name" for further information. Type "HELP specify versions" for further information about specifying versions of dictionary objects. destination-path-name Locates the dictionary directory or subdictionary into which the specified portions of the directory hierarchy are copied. You cannot use any wildcards in the destination path name. If you do not specify a destination path name, DMU uses your current default directory. Type "HELP specify path-name" for further information.
2 – privileges
o You need PASS_THRU and SEE at the dictionary directories,
subdictionaries, and objects you want to copy.
o You need PASS_THRU and EXTEND at the destination directories and
subdictionaries, and you need UPDATE at dictionary objects as you
create them.
o You need HISTORY at both the source and destination to use the
/AUDIT qualifier.
o You need PASS_THRU, SEE, and UPDATE at the highest existing
version of an object in the destination directory to create a new
version with /VERSION.
o You need CONTROL at both the source and destination directories
to use the /PROTECTION qualifier. If you are using /VERSION, you
need CONTROL at the highest existing version of the object in the
destination directory in order to copy the access control list of
the object in the source directory.
3 – qualifiers
3.1 /AUDIT
Syntax:
/AUDIT [= (quoted-string [, quoted-string]...)]
/AUDIT=file-specification
/NOAUDIT
Use /AUDIT to create history list entries auditing the copy in the
history lists of both source and destination dictionary directories,
subdictionaries, and objects.
You can include explanatory text in history list entries in three
ways:
o By specifying the /AUDIT qualifier. If you include no quoted
string or file-specification, DMU provides a default history list
entry describing your operation.
o By including quoted strings. Enclose each quoted string in
double quotation marks, and enclose the series of strings in
parentheses. The parentheses are optional if you specify only
one quoted string.
o By specifying a file whose contents are to be included in the
history list entry. The file specification is a standard VMS
file specification, and the default file type is .DAT. You can
include no more than 64 input strings in a history list entry.
DMU ignores any excess.
With /NOAUDIT, no history list entries are created. The default is
/NOAUDIT.
3.2 /HISTORY
Syntax
/[NO]HISTORY
Use /HISTORY to copy history lists. Use /NOHISTORY to exclude
history lists from the information that is copied. When you use
/NOHISTORY with /VERSION, the copied object receives the history list
of the highest existing version of the object in the destination
directory.
The default is /NOHISTORY.
3.3 /LOG
Syntax:
/LOG [= file-specification]
/NOLOG
Use /LOG to create a list of the given names of all of the dictionary
directories, subdictionaries, and objects copied.
The file specification is a standard VMS file specification naming
the file into which the log is written. The default file type is
.LOG. If you use /LOG without specifying a file, DMU writes the log
to SYS$OUTPUT. With /NOLOG, no list is created.
The default is /NOLOG.
3.4 /PROTECTION
Syntax:
/[NO]PROTECTION
Use /PROTECTION to copy access control lists. Use /NOPROTECTION to
exclude access control lists from the information that is copied. If
you use /NOPROTECTION with /VERSION, the object receives the access
control list of the highest existing version of the object in the
destination directory.
The default is /NOPROTECTION.
3.5 /STAGE
Syntax:
/[NO]STAGE
Use /STAGE to withhold committing changes in the CDD until the entire
copy is completed. Use /NOSTAGE to make changes in the CDD as each
dictionary directory, subdictionary, or object is copied.
Using /STAGE assures that no changes remain in the dictionary if a
command is interrupted. However, with /STAGE, execution time
increases exponentially with the number of directories,
subdictionaries, and objects copied.
With /NOSTAGE, execution time increases linearly with the number of
directories, subdictionaries, or objects copied. However, if you
interrupt an unstaged COPY command, some of the changes remain in the
dictionary.
The default is /NOSTAGE.
3.6 /VERSION
Syntax:
/[NO]VERSION
Use /VERSION to copy objects to a directory where an object with the
same name already exists. The new objects in the destination
directory have the same version numbers as the original objects from
which they were copied, regardless of whether you specified version
numbers in the source path names. Unless there is an object in the
destination directory with the same name as an object you are
copying, there is no need to use /VERSION.
Use /NOVERSION to guarantee that the destination directory does not
already contain an object with the same name as the object you are
copying. /NOVERSION is the default.
The results of using the /VERSION qualifier vary depending on the
existing children of the target directory.
o COPY/VERSION copies an object to a destination directory if the
destination directory does not already contain an object with the
same name and same version number as the source object. In this
case, DMU copies the specified version of the object in the
source path name to the destination directory. The new object
has the same version number as the source object.
o COPY/VERSION copies an object to a destination directory and
issues an informational message if the destination directory
already contains an object with the same name and a higher
version number. For example, you specify TEST_REC;2 and the
destination directory contains TEST_REC;3. In this case DMU
creates the object with the same name and version number as the
source object, then issues the informational message.
o COPY/VERSION does not copy an object if the destination directory
contains an object with the same name and version number as the
source object. For example, you specify TEST_REC;2 and the
destination directory already contains TEST_REC;2.
By default, a new version of an object has the same access control
list and history list as the highest existing version of the object
in the destination directory. You can copy the access control list
from the source by using the /PROTECTION qualifier with /VERSION. To
copy the access control list, you must have CONTROL (C) privilege at
the highest existing version of the object in the destination
directory. You can copy the history list from the source by using
/HISTORY with /VERSION.
