Dictionary/3000 Reference Manual (32244-90001)

Preface
This manual describes the Dictionary/3000 software system that operates on HP 3000
computers. It is the reference document for all persons involved in creating and
maintaining a dictionary database and an IMAGE/3000 data base. It assumes a working
knowledge of the HP 3000 computer system, including the IMAGE/3000 subsystem.
This edition of the manual has been expanded to include the new Dictionary extract
utilities for COBOL II/3000 and PASCAL/3000 data declarations, and for the new VPLUS
forms file definition utility. In order to use these utilities, the manual assumes a working
knowledge of COBOL II/3000, PASCAL/3000, and VPLUS/3000. Also included in this
manual is information for the Inform Security feature.
In addition, use of the Dictionary audit, load, and unload utilities can improve
IMAGE/3000 response and allows faster application run time and increased throughput.
Each utility provides benefits which are not included in IMAGE. For example, the primary
benefit of the load and unload utilities, DICTDBL and DICTDBU, is that they allow
selective loading and unloading of the data sets within a database. These can be used as
tool to maintain the primary path sequence of the data in detail data sets. (DICTDBU and
DICTDBL do not, however, provide a dynamic restructuring capability.) For full database
loads and unloads, the DBLOAD and DBUNLOAD facilities provided with IMAGE are
more efficient.
DICTDBA, the audit utility, gives you a quick way to find out the synonym chain count and
average chain length. By maintaining chain counts as low as possible, database
performance is improved.
