SDUTIL Overview
The HP System Dictionary/V Utility (SDUTIL) is a general purpose program
which provides you with the capability to
* create compiled dictionaries.
* merge dictionary data.
* rename a compiled dictionary.
* purge a dictionary.
These functions are described below.
Compiled Dictionaries
System Dictionary now includes two types of dictionaries which contain
metadata:
* Master Dictionaries. A master dictionary consists of a TurboIMAGE
database which can be accessed by all System Dictionary intrinsics
and SDMAIN commands. Because of its complexity, however, the
response time while using a master dictionary may be a problem for
some subsystems, especially those which must read from the dictionary
at run-time.
* Compiled Dictionaries. A compiled dictionary contains metadata
extracted from a master dictionary. Like a compiled program, a
compiled dictionary cannot be modified. It is therefore a read-only
dictionary which can be accessed by those System Dictionary
intrinsics and commands which only read dictionary metadata.
Compiled dictionaries provide faster dictionary read access and are
intended to be used by subsystems and applications that need only to read
the metadata. A compiled dictionary is less complex than a master
dictionary and is compacted into one or more flat files. It therefore
requires less disk storage space, and provides a more efficient means of
transporting dictionary data to other groups, accounts, or systems.
Merging Dictionaries
SDUTIL provides you with the capability to selectively merge certain
dictionary data into appropriate areas of the same or other dictionaries
as follows:
* Dictionary structure definitions can be merged into the structure of
another dictionary.
* Occurrences from a version in a dictionary can be merged into another
version in the same or another dictionary.
* Security definitions from one dictionary can be merged into the
security scheme in another dictionary.
SDUTIL allows you to preview the results of the merge operation and
provides you with information about conflicts which will occur if the
merge is allowed to continue. You can then decide whether or not to do
the actual merge operation. Note that it is also possible to merge
dictionary data and compile it during the same session.
Renaming a Compiled Dictionary
Unlike master dictionaries, compiled dictionaries do not have to be named
SYSDIC. Therefore, SDUTIL provides you with the capability of renaming a
compiled dictionary. This function may be particularly useful to prevent
name conflicts with other dictionaries when moving a compiled dictionary
to another group, account, or system.
Purging a Dictionary
SDUTIL provides you with the capability of purging either master or
compiled dictionaries. Note that if a master dictionary is purged, all
files associated with that dictionary (SYSDICxx) will also be purged.
