A
assigned message flow
In Version 2.1, a message flow that is assigned to an execution group. In Version 6.0, when you add a message flow to a broker archive (bar) file and deploy the bar file to an execution group, the message flow is assigned implicitly to the execution group.
assigned message flow properties
In Version 2.1, the properties of an assigned message flow. In Version 6.0, you specify the equivalent properties in the deployment descriptor of a broker archive (bar) file.
assigned message set
In Version 2.1, a message set that is assigned to a broker. In Version 6.0, when you add a message set to a broker archive (bar) file and deploy the bar file to an execution group, the message set is assigned implicitly to the execution group.
Assignments view
In Version 2.1, the user interface in the Control Center that is used to assign message flows to an execution group and message sets to a broker. In Version 6.0, the equivalent function is provided by the Broker Administration perspective of the workbench. When you add message flows and message sets to a broker archive (bar) file and deploy the bar file to an execution group, the message flows and message sets are assigned implicitly to the execution group.
B
base message set
In Version 2.1, a finalized message set upon which another message set is based. The two message set definitions are linked and the definition of the base message set can never be modified. In Version 6.0, when you base a message set on another message set, the workbench makes a copy of the definition of the base message set. Subsequently, the two message set definitions are completely separate from each other and can be modified independently.
base type
In Version 2.1, a compound type as a whole can have a simple value. The type of this simple value is called the base type. In Version 6.0, a base type is the simple type or complex type upon which another type is based.
Broker Administration perspective
In Version 6.0, a broker administration console that communicates with one or more Configuration Managers. Administrators work in this perspective to manage the resources (also referred to as domain objects) in the broker domain that are defined on one or more Configuration Managers. In Version 2.1, the equivalent function is provided by the Assignments view.
built-in node
In Version 6.0, a message processing node that is supplied by the product. In Version 2.1, this is referred to as an IBM Primitive node.
C
check in
In Version 2.1, a Control Center action that stores a new or updated resource in the Configuration Manager. In Version 6.0, the equivalent check-in function might be provided by an external repository that is associated with the workbench.
check out
In Version 2.1, a Control Center action that extracts a resource from the Configuration Manager and locks it for local modification by a user. In Version 6.0, the equivalent check-out function might be provided by an external repository that is associated with the workbench.
C language binding
See language binding.
COBOL language binding
See language binding.
complex type
In Version 6.0, a type that has structure. In Version 2.1, this role is performed by a compound type.
compound type
In Version 2.1, this has two roles:
  • A type that has structure. In Version 6.0, this is referred to as a complex type.
  • A collection of elements. In Version 6.0, this is referred to as a group.
Composition
In Version 6.0, a property that describes how a message tree is structured. In Version 2.1, the equivalent property of a compound type is Type Composition.
Configuration Manager
In Version 6.0, the Configuration Manager does not store message flow and message set definitions. Instead, these definitions are stored in the local file system or in an external repository that is associated with the workbench. In addition in Version 6.0 the Configuration Manager no longer uses an external database to store the domain configuration, but uses an internal repository instead.
connection
In Version 6.0, this represents the flow of control and data between two message processing nodes. In Version 2.1, this is referred to as a connector.
Connection pane
In Version 2.1, a pane that is used to specify certain properties of an element or compound type. In Version 6.0, these properties are specified as the logical properties of an element reference or group reference.
connector
In Version 2.1, this represents the flow of control and data between two message processing nodes. In Version 6.0, this is referred to as a connection.
Content Validation
In Version 6.0, a property of a group. In Version 2.1, the equivalent property applies to a compound type and is called Type Content.
context tag
See element qualifier.
Control Center
In Version 2.1, the graphical user interface that provides the function to define, configure, deploy, and monitor resources. In Version 6.0, this function is provided, with enhancements, by the Message Brokers Toolkit, which is also known as the workbench.
customizer
In Version 2.1, a means of specifying complex properties of a message processing node. In Version 6.0, you use an editor to perform this task.
D
debugger
In Version 2.1, a tool that is accessed from the Message Flows view in the Control Center and enables message flows to be debugged. In Version 6.0, similar but enhanced function is provided by the flow debugger.
Description pane
In Version 2.1, a pane that is associated with every object and that is used to specify the Short Description and Long Description properties of the object. In Version 6.0, some objects still have short and long descriptions, but message model objects have a documentation property instead.
documentation property
In Version 6.0, the documentation property of an object allows you to add information to enhance the understanding of that object's function. In Version 2.1, the equivalent information is provided using the Description pane.

E

element member
In Version 2.1, an object that represents the membership of an element within a compound type. In Version 6.0, the object that represents the membership of a global element within a complex type or group is called an element reference.
element qualifier
In Version 2.1, an object that is associated with an element in a message to enable that element to be treated differently in different contexts. It is also known as a context tag. In Version 6.0, element qualifiers are no longer used.
element reference
In Version 6.0, an object that represents the membership of a global element within a complex type or group. In Version 2.1, the object that represents the membership of an element within a compound type is called an element member.
element value
In Version 2.1, a named value that you can use to specify a value constraint on an element. In Version 6.0, element values are no longer used. Instead, you associate value constraints with a simple type.
extended decimal
In Version 2.1, a Custom Wire Format (CWF) physical representation of a number. In Version 6.0, this is referred to as external decimal.
external decimal
In Version 6.0, a Custom Wire Format (CWF) physical representation of a number. In Version 2.1, this is referred to as extended decimal.
F
finalize
In Version 2.1, the action to put a message set into a finalized state. When a message set is in this state, you can never modify its definition again. In Version 6.0, a message set cannot be finalized.
flow debugger
In Version 6.0, a facility to debug message flows that is provided in the Debug perspective in the workbench. In Version 2.1, the equivalent function is provided by the debugger.
freeze
In Version 2.1, the action to put a message set into a frozen state to prevent further modification to its definition. See also unfreeze. In Version 6.0, a message set cannot be frozen.
G
glossary
In Version 2.1, a form of documentation in HTML format that you can generate from a message set definition. In Version 6.0, this has been replaced by message set documentation, which is also in HTML format.
group
In Version 6.0, a structure that can be included in a complex type or another group. In Version 2.1, this role is performed by a compound type.
H
History pane

In Version 2.1, a message processing node that is supplied by the product. In Version 6.0, this is referred to as a built-in node.
identifier
In Version 2.1, an identifier that identifies each object uniquely within a message set. You use the identifier to reference the object in an ESQL statement. In Version 6.0, an object is identified by its name only. When you migrate a message set, the name of an object is formed from its Version 2.1 identifier.
Input Compression Technique
In Version 2.1, a Tagged Delimited String (TDS) property of a message set. In Version 6.0, this property does not exist.
Input Terminal node
In Version 2.1, an IBM Primitive node through which a message is received by a subflow. In Version 6.0, this function is provided by the Input node.
L
language binding
In Version 2.1, a set of properties associated with a message set that enable you to generate a C header or COBOL copy book from the message set definition. In Version 6.0, this set of properties does not exist, and it is not possible to generate a C header or COBOL copy book from a message set definition.
Level
In Version 2.1, a property of a message set that specifies the version of the message set. In Version 6.0, this property does not exist.
Long Description
See Description pane.
M
message book
In Version 2.1, a form of documentation in HTML format that you can generate from a message set definition. In Version 6.0, this has been replaced by message set documentation, which is also in HTML format.
Message Brokers Toolkit
In Version 6.0, the development and operational management environment for a broker domain. It is also referred to as the workbench. In Version 2.1, the Control Center provides this function.
message category
In Version 6.0, a way of grouping messages, perhaps for documentation or convenience purposes, or for assisting in the generation of Web Services Description Language (WSDL) files. This replaces the Version 2.1 transaction and transaction category.
message repository
In Version 2.1, the set of database tables used by the Configuration Manager to store message set definitions. In Version 6.0, there is no message repository, and message set definitions are stored in the local file system or in an external repository that is associated with the workbench.
Message Repository Manager
In Version 2.1, the component of the Configuration Manager that manages message set definitions in the message repository. In Version 6.0, there is no Message Repository Manager.
message set documentation
In Version 6.0, documentation in HTML format that you can generate from a message set definition. In Version 2.1, the equivalent documentation is provided by a glossary and a message book.
MRM
In Version 2.1, the name of a message domain and the abbreviation for Message Repository Manager. In Version 6.0, it is the name of only a message domain.
N
name
In Version 2.1, a descriptive name of an object in a message set. This name is not used to identify the object in an ESQL statement; the identifier of the object is used instead. In Version 6.0, the name is used to identify an object and must be a valid XML Schema identifier. When you migrate a message set, the name of an object is formed from its Version 2.1 identifier.
O
Operations view
In Version 2.1, the Control Center view that is used to manage and monitor the brokers in a broker domain. In Version 6.0, the equivalent function is provided by the Domains and Alerts views in the Broker Administration perspective of the workbench.
Output Compression Technique
In Version 2.1, a Tagged Delimited String (TDS) property of a message set. In Version 6.0, this property does not exist.
Output Terminal node
In Version 2.1, an IBM Primitive node through which a message is propagated by a subflow. In Version 6.0, this function is provided by the Output node.
P
plug-in
In Version 2.1, a user-written extension to the broker that provides a message processing node or message parser in addition to those supplied with the product. In Version 6.0, this is referred to as a user-defined extension.
prefixed identifier
In Version 2.1, an identifier that contains a prefix to ensure that the identifier is unique within a message set. Use prefixed identifiers in situations where different elements have the same name so that the element is defined globally even though it is considered to be local to a compound type of which it is a member. In Version 6.0, prefixed identifiers are no longer required because an element can be defined locally. When you migrate a message set, an element with a prefixed identifier becomes a local element, and the prefix is discarded when the identifier is used to form the Version 6.0 name.
R
Run Time pane
In Version 2.1, the pane that is used to specify the runtime parser for a message set. In Version 6.0, this information is specified as a general message set property.
S
shared data
In Version 2.1, configuration repository and message repository data that is shared by Control Center users. In Version 6.0, the equivalent functionality might be provided by an external repository that is associated with the workbench.
Short Description
See Description pane.
simple type
In Version 2.1, one of seven types defined by the MRM to describe an item of data. In Version 6.0, a simple type is one of the 44 XML Schema simple types or a user-defined simple type.
Simple Unordered Set
In Version 2.1, one of the permissible values of the Type Composition property of a compound type. It is intended for the modelling XML DTD attribute list declarations. In Version 6.0, this value is not required because XML Schema attribute groups are modelled as objects in their own right. If the Type Composition property of a compound type has this value when you migrate a message set, the Composition property of the group that is formed from the compound type has the value All, if the Type Content property of the compound type has the value Closed, or the value Unordered Set otherwise.
suspended from use
In Version 2.1, certain MRM objects in a message set that is based on another message set can be suspended from use. When suspended from use, an object cannot be used. In Version 6.0, an object cannot be suspended from use.
T
traffic light status icon
In Version 2.1, an icon next to a message flow, execution group, or broker in the Domain Topology pane of the Operations view in the Control Center. A green traffic light indicates that the resource is running, and a red traffic light indicates that it is not running. In Version 6.0, an alert appears in the Alerts view in the Broker Administration perspective of the workbench only when the resource is not running.
transaction
In Version 2.1, a group of messages that are considered to be part of a single business transaction. In Version 6.0, transactions are no longer used. When you migrate a message set, a transaction is replaced by a message category that contains the same messages as the original transaction.
transaction category
In Version 2.1, a group of transactions within a message set. In Version 6.0, transaction categories are no longer used. When you migrate a message set, a transaction category is replaced by a message category. This message category contains all the messages in all the transactions that were members of the original transaction category.
Type Composition
In Version 2.1, a property of a compound type. In Version 6.0, the equivalent property applies to a group and is called Composition.
Type Content
In Version 2.1, a property of a compound type. In Version 6.0, the equivalent property applies to a group and is called Content Validation.
U
unfreeze
In Version 2.1, the action to remove a message set from a frozen state to allow further modification to its definition. In Version 6.0, a message set cannot be frozen.
unlock
In Version 2.1, the action to end the checked-out state of a resource in such a way that any changes made to the resource since it was checked out are not stored in the Configuration Manager. In Version 6.0, the equivalent function might be provided by an external repository that is associated with the workbench.
user-defined extension
In Version 6.0, a user-written extension to the broker that provides a message processing node or message parser in addition to those supplied with the product. In Version 2.1, this is referred to as a plug-in.
V
value constraint
In Version 2.1, the use of an element value to specify a constraint on the value of an element. In Version 6.0, a value constraint is represented by an XML schema facet that is applied to a simple type.
view
In Version 2.1, a user interface in the Control Center that enables a user to perform a specified task. There are eight views: Message Sets, Message Flows, Topology, Assignments, Topics, Operations, Subscriptions, and Log. In Version 6.0, a view is a component of a perspective in the workbench. To perform a specified task, the user selects the appropriate perspective and then uses a combination of one or more views and an editor.
