IBM MQ messaging provider activation specification settings
Use this panel to view or change the configuration properties of the selected activation specification for use with the IBM MQ messaging provider. These configuration properties control how connections are created to associated queues and topics.
- In the navigation pane, click to display existing activation specifications.
- If appropriate, in the content pane, change the Scope setting to the level at which the activation specifications are defined. This restricts the set of activation specifications displayed.
- Select the name of the activation specification that you want to work with.
- Advanced properties to display or change the advanced properties of your IBM MQ activation specification.
- Broker properties to display or change the broker properties of your IBM MQ activation specification.
- Custom properties to display or change the custom properties of your IBM MQ activation specification. For example, you would use this option to set the custom property WAS_EndpointInitialState for an activation specification. WAS_EndpointInitialState determines whether or not message consumption begins from the JMS destination as soon as the activation specification is used for a message-driven bean to connect with the destination.
- Client transport properties to display or change the client transport properties of your IBM MQ activation specification. If the selected activation specification was not created using a Client Channel Definition Table (CCDT), follow this link to enter all the information required to connect to IBM MQ. If the selected activation specification was created using a CCDT, you do not need to supply the client transport properties, and so the link is absent.
Under Related Items, you can click JAAS - J2C authentication data to configure authentication information for use with the activation specification.
You can also specify the -localAddress property by using the createWMQActivationSpec IBM MQ administrative command.
- Names can have a maximum of 48 characters, with the exception of channels, which have a maximum of 20 characters.
- The property values that you specify must match the values that you specified when configuring IBM MQ for JMS resources. For more information, see the Using Java™ and System Administration sections of the IBM MQ documentation.
If IBM® MQ functionality has been disabled at a scope that affects this IBM MQ messaging provider resource, then an informational message indicating that IBM MQ has been disabled appears. In a single server environment this informational message is only displayed when the server is restarted after IBM MQ functionality has been disabled. In a network deployment environment the informational message is displayed immediately.
An IBM MQ activation specification has the following properties.
Administration
Scope
The level to which this resource definition is visible to applications.
Resources such as messaging providers, namespace bindings, or shared libraries can be defined at multiple scopes, with resources defined at more specific scopes overriding duplicates that are defined at more general scopes.
The scope displayed is for information only, and cannot be changed on this panel. If you want to browse or change this resource (or other resources) at a different scope, change the scope on the IBM MQ activation specification collection panel, then click Apply, before clicking the link for the type of resource.

Enter host and port information in the form of separate host and port values
If this radio button is selected, this means that the connection to the IBM MQ queue manager is made using the information supplied by the host name and port properties.
Selecting this option enables the host name and port properties, and disables the connection name list property. To enter connection name list information, click Enter host and port information in the form of a connection name list.
This radio button is only available if the scope property specifies a cell or cluster, or if the scope property specifies a node or server and that node or server is running WebSphere Application Server Version 8.0 or later.
Information | Value |
---|---|
Data type | Radio button |
Hostname
The host name, IPv4, or IPv6 address of the IBM MQ queue manager to connect to.
Information | Value |
---|---|
Data type | String |
Port
The port number on which IBM MQ is listening.
Information | Value |
---|---|
Data type | Integer |
Default | 1414 |
Range | The value must be in the range 1 to 65536 (inclusive). |
Enter host and port information in the form of a connection name list
If this radio button is selected, this means that the connection to the IBM MQ queue manager is made using the information supplied by the connection name list property.
Connection name lists can be used to connect to a single queue manager or to a multi-instance queue manager. For more information on using a multi-instance queue manager, see the IBM MQ information centre. Selecting this option enables the connection name list property and disables the host name and port properties. To enter separate host and port information, click Enter host and port information in the form of separate host and port values.
This radio button is only available if the scope property specifies a cell or cluster, or if the scope property specifies a node or server and that node or server is running WebSphere Application Server Version 8.0 or later.
Information | Value |
---|---|
Data type | Radio button |
Connection name list
The connection name list specifying the host name and port details to use when you want the activation specification to connect to a multi-instance queue manager.
This property must only be used to allow connection to a multi-instance queue manager. It must not be used to allow connections to non-multi-instance queue managers as that can result in transaction integrity issues.
Information | Value |
---|---|
Data type | String |
Default | Unset |
Range | This field must be set to a string in the following form:
host[(port)][,host(port)] The port information is optional, and if not specified, defaults to 1414. host must be a valid TCP/IP host name or IPv4 or IPv6 address. port must be an integer value in the range 1 to 65536 (inclusive). For example: localhost(1234),remotehost1(1234),remotehost2 |
When the connection name list property is specified, the host name or port properties are automatically set to the host name and port number of the first entry in the connection name list. So if you specified localhost(1234),remotehost1(1234),remotehost2, the host name would be set to localhost and port would be set to 1234.
This property is only available if the scope property specifies a cell or cluster, or if the scope property specifies a node or server and that node or server is running WebSphere Application Server Version 8.0 or later.
- For nodes running at a fix pack level of WebSphere Application Server Version 7.0 Fix Pack 7 or later, the connection name list property can be used to connect to multi-instance queue managers.
- For nodes running at a fix pack level earlier than Version 7.0,
the connection name list property is not recognized, and a warning message similar to the following
example is output:
In this case the information in the host name and port properties are used to connect to a queue manager.[29/09/10 12:15:27:468 BST] 00000018 J2CUtilityCla W J2CA0008W: Class com.ibm.mq.connector.inbound.ActivationSpecImpl used by resource cells/L3A3316Node01Cell/resources.xml#J2CResourceAdapter_1284547647859 did not contain method setConnectionNameList.

Data type | Check box. If this check box is cleared, the following SSL properties are disabled:
|
Centrally managed
When the SSL protocol is used to communicate with IBM MQ, select this radio button to specify that the SSL configuration is taken from the centrally managed WebSphere Application Server SSL configuration.
When you select this radio button, the host name and port attributes from the IBM MQ messaging provider activation specification are used to select an appropriate SSL configuration. If host and port information has been supplied to the activation specification by a connection name list this means that the host name and port information of the first element in the list are used to select an appropriate SSL configuration. To provide the SSL configuration which will be matched to the activation specification, see the Dynamic outbound endpoint SSL configuration settings topic listed under related reference.
Information | Value |
---|---|
Data type | Radio button |
Specific configuration
Select this radio button when you want to specify a particular SSL configuration for use when SSL is to be used to secure network communications with the IBM MQ queue manager or queue-sharing group.
