The related services include those functions that can potentially have a common
syntax, but whose semantics cannot be defined in a common manner across all
environments; for example, querying system defaults or the current session CCSID.
The resource management functions are contained in the group of related services.
These functions are system-specific because they deal with system-specific resource
structures, access, and storage; and they provide system-specific administration
facilities (utilities and their end-user interfaces).
Functions that are not common within a system are object-manager-specific (for
example, querying the CCSID of a relational database table). These functions
may have a common object-manager-specific syntax across systems. The functions
and their syntaxes cannot be supported as common services in all environments.
Brief descriptions of related services follow.
Setting Tag Values
Setting is the process of entering one or more tag values into the tag fields
associated with different graphic character data elements. The set function
is provided as part of the various object-manager-specific interfaces, or associated
service functions. Setting of tag fields on entities owned by the operating
system is provided by the system-specific interfaces. Setting is usually performed
at object create time, and may be modified if the data encoding changes.
Querying Tag Values
Querying is the process of reading or obtaining one or more tag values associated
with graphic character data elements. The query function is provided as part
of various object-manager-specific interfaces, or associated service functions.
Querying of tag fields in entities (or objects) owned by the operating system
is provided by services in the operating system, as part of the system-specific
services.
The query function also resolves any unknown or default tag values such as
a CCSID value of X'0000'. Any hierarchy used for organizing the different elements
owned by the object managers is object-manager-specific. Different types of
queries are applicable to different object managers. For example, a file manager
may provide for querying all the CCSIDs that may be present within a file; a
presentation manager may provide for querying the CCSID used in a currently
active window.
To assist in resolving the defaults in a hierarchy, a function may be provided
to create and maintain a resource of default values for an application, a user,
or another module. This resource is system-specific.
Resource Management Functions
Different systems have different structures and different methods of storing
information resources. The content of the CDRA-supporting resources is defined
by the architecture; however, the manner in which the resources are stored is
system-specific as are the functions for maintaining (creating, updating, and
querying) them. These functions, when provided, are classed as related services.
