CA-supplied Dictionary Definitions

Provided on Install Tape

As part of installation, you receive definitions for entities required to operate your CA IDMS environment. These definitions are described next:

Definition	Description
Non-SQL descriptions of the dictionary	A schema and subschemas describing the base definition and message components and that part of the catalog component used for physical database definitions
At sites with the SQL option, an SQL description of the catalog component	Table definitions of the catalog component of the SYSTEM schema and views based on those tables in the SYSCA schema
Runtime messages	Messages used by CA-written software
Entity, class, and attribute definitions	Definitions of base entity, class, and attributes used by CA IDMS tools
Protocols and standard error routines	Generalized source modules that the DML processors use to convert DML statements into calls for DBMS services
DC/UCF device types, task, and program definitions	Definitions used to generate DC/UCF systems
CA Culprit report modules	CA Culprit source modules used to produce standard reports; for example, JREPORTs, SREPORTs, and DREPORTs
Nondatabase structures	Records that are not associated with a CA IDMS database. CA IDMS/DB stores the definitions of nondatabase structures as records in the dictionary; applications can copy the definitions of the records at compile time by means of COPY IDMS or INCLUDE IDMS compiler-directive commands.

How the Dictionary Gets Populated

Dictionaries are populated with CA-supplied definitions in one of three ways:

Definition	Description
IDMSDIRL	Loads the non-SQL schema and subschemas that define the base definition and message components of the dictionary
IDD, IDMSCHEM, IDMSUBSC	Populates the base definition and message components of the dictionary using source members provided at installation
Command facility	Populates the catalog component of the dictionary with system table and view definitions (SQL-option only)

Where Information Should Reside

The information listed above can reside in either a system dictionary or an application dictionary, or both:

Information	Where it should reside
Non-SQL schema and subschema describing the dictionary	In one dictionary associated with each system; the definitions may be shared across systems
SQL definitions	In all dictionaries having a catalog component (SQL-option only)
Messages	In all system message areas
Entity, class, and attribute definitions	In all system and application dictionaries
Protocols and standard error routines	In all application dictionaries
DC/UCF device types, task, and program definitions	In all system dictionaries
CA Culprit report modules	In the same dictionary that contains the non-SQL schema and subschema definitions of the dictionary
