The UMA Configuration Class
This chapter describes the "UMA Configuration" class and its
subclasses.
Messages in this class give data pertaining to the specific UMA
implementation, data providers, and to the UMA configuration
parameters on this
particular system.
This class is an MLI-only class, created from the examination of the
name space.

shows the implementation status of a given class. The value of each
array element will be one of NOTIMPLEMENTED, DISABLED, or ENABLED.

this class is implemented, but was omitted from the system at
configuration time or disabled dynamically, ENABLED means that this
class is available to be collected.

gives the index of the first subclass of this class in the subclass
status array.
- (B)UMAUint4[]

class-subclass index plus the subclass id gives the implementation
status of basic segment of this subclass. The possible values are
the same as in the class status array.
- (B)UMAUint4[]
- the subclass optional status array. This array, when indexed by the
class-subclass index plus the subclass id gives the implementation
status of optional segment of this subclass. The possible values are
the same as in the class status array.
- (B)UMAUint4[]
- the subclass extension status array. This array, when indexed by the
class-subclass index plus the subclass id gives the implementation
status of extension segment of this subclass. The possible values are
the same as in the class status array.

index gives the count of field sequence ids implemented for this subclass.

subclass-field index plus the field sequence id gives the implementation
status of this field in the basic segment. The possible values are
the same as in the class status array.
- (B)UMAUint4[]
- the subclass optional status array. This array, when indexed by the
subclass-field index plus the field sequence id gives the implementation
status of this field in the optional segment. The possible values are
the same as in the class status array.

- the subclass extension status array. This array, when indexed by the
subclass-field index plus the field sequence id gives the implementation
status of this field in the extension segment. The possible values are
the same as in the class status array.

the specified class/subclass, and has not yet issued a
umaRelease().

class-subclass index plus the subclass id shows the session's state of a
given class/subclass extension segment. The value of each array element will

the obvious meaning. HELD means that the session has started
the specified class/subclass, and has not yet issued a
umaRelease().
