Change only

The method of CA IDMS Dictionary Migrator execution which limits selection to changed entities only.

Entry point

The entity that serves as a gateway (for CA IDMS Dictionary Migrator) to the entities that are to be extracted from the source dictionary. You specify the entry point in the EXTRACT statement. For example, in the statement

EXTRACT, SUBSCHEMA=subschema-name, LEVEL=DIALOG

the subschema that has been specified is the entry point.

Extract path

The route CA IDMS Dictionary Migrator follows through the dictionary's set connections from the entity specified in the EXTRACT statement to all of its related components. What you include in the EXTRACT statement determines the beginning and direction of this route. For example, if you enter this statement:

EXTRACT, SUBSCHEMA=subschema-name, LEVEL=ENTITY

CA IDMS Dictionary Migrator will follow the dictionary set connections from the subschema that you specify to all related records and all of the elements related to the records.

Migration

The movement of entities from one or more source dictionaries to an object dictionary. Migration is comprised of extracting entities from one or more source dictionaries, checking the effect of source dictionary entities upon the object dictionary, creating the syntax necessary for input to the CA IDMS compilers, and uploading the entities into the object dictionary.

Object dictionary

A dictionary which acts as the destination for entities that are moved during the migration process. Your object dictionary is populated by entities that are copied from your source dictionary(s). Only one object dictionary can be used during each migration.

Source dictionary

The dictionary which acts as a reservoir for entities that are available for migration into another (object) dictionary. Your source dictionary is not changed during the migration process. Multiple source dictionaries can be used during each migration. And, if you desire, you can use your object dictionary as a source dictionary.

Starting point

This entity and all of its related entities are copied into your object dictionary. You determine what the starting point is by specifying the entry point and whatever option you choose to include in the LEVEL parameter. For example, in the statement

EXTRACT, SUBSCHEMA=subschema-name, LEVEL=DIALOG

the dialog (or dialogs) related to the subschema that you specified is the starting point.

Syntax files

A collection of files that contain source statements used as input to the CA IDMS utilities and compilers. The syntax files permit completion of the movement of entities and entity components from one or more source dictionaries to the object dictionary.

Trace

To identify an entity, its related entities, its related components, and all of the connections among these entities.
