generation

1) The process that creates and stores a load module in the DDLDCLOD or DDLCATLOD areas of the dictionary. Load modules can be generated by the application compiler, the dialog compiler, the OCF compiler (DMCL, database name table, and access module load modules), the DDDL compiler (edit and code tables), the mapping facility (the map load module), and the subschema compiler (the subschema load module). 2) In ASF, the process that automatically creates one subschema definition, syntax module, and load module per subschema. A subschema is automatically created for each table that is defined and generated. 3) In system generation, the process of validating the system definition and updating the definition to make the system executable.

generic key

A partial symbolic key. A generic key is typically used to identify a group of related record occurrences. For example, given a symbolic key based on a customer name field, an appropriate generic key might consist of only the first letter of this field; the generic key could be used to access record occurrences for all customers whose names begin with a certain letter.

GET

The navigational database access function that retrieves a located record (that is, the record that is current of run unit) by copying its contents from the database to variable storage. Before issuing GET, an application program typically issues the FIND function to locate the appropriate record occurrence in the database. See also FIND.

global cursor

A cursor that can be used by other application programs sharing the access module that contains the cursor definition. You define a global cursor by including the GLOBAL keyword in the DECLARE CURSOR statement. See also cursor, external cursor, shared cursor, updatable cursor.

global DMCL

A DMCL module that defines all database areas accessed by all transactions executing under the CA IDMS/DB central version. See also DMCL module.

global locking

The use of a lock structure in the Coupling Facility in the IBM parallel sysplex environment for recording and managing global locks. CA IDMS/DB uses global locks to control Data Sharing group inter-member access to shared resources.

global record

In CA ADS, a record that is available to all functions of an ADSA-defined application. A global record remains in the record buffer for the duration of the application, unaffected by dialog control commands. Global records for a given application are named on the Global Records screen in the application compiler. See also ADSO-APPLICATION-GLOBAL-RECORD.

global resource

Within centralized security, an entity that is defined in the user catalog and that is shared by all systems in the CA IDMS security domain. Types of global resources are user, group, and user profile. See also user profile, system resource, database resource.

global response

In the CA ADS application compiler, an application response that is automatically valid for all application functions when the application is being defined or modified.

The application developer can selectively disable a global response from specific functions at definition time. At runtime, the response is available from all functions except for those functions from which it is deselected. The opposite of a global response is a local response.

graphics literal

A double-byte character set string interpreted without shiftin and shiftout characters.

group

In CA ICMS and in centralized security, a collection of related users. Groups can include users and other groups.

group element

In IDD, an element that contains subordinate elements. For example, the DATE element is a group element that contains elements MONTH, DAY, and YEAR.

grouped view

A view that includes a GROUP BY or HAVING parameter in the query specification.
