Documentation Overview
This part of Volume 2 of the General Reference Manual describes the HP System Dictionary Utility,
SDUTIL, and provides detailed operating information and instructions for its use.
•"Introduction",provides a description of the features and benefits of the program.
•"Running the SDUTIL Program " , describes the files required by the program, its run options, oper-
ating modes, and user input rules.
•"SDUTIL Commands " , describes the SDUTIL commands and their syntax. Each command descrip-
tion includes a description of each of the parameters used in that command.
• Appendix A provides a list of the error messages for SDUTIL, and includes at least one possible cause
for each error and an action to take for each cause given.
• Appendix B provides a listing of the SDUTIL commands and the abbreviation for each command.
SDUTIL Overview
The HP System Di ctionary/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 Dicti onary 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.
• CompiledDictionaries. Acompileddictionarycontainsmetadataextracted fromamasterdictionary.
Likea compiled program, acompiled dictionary cannot bemodified. It istherefore 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 m erge 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.
