createWMQActivationSpec command

Use the createWMQActivationSpec command to create an activation specification for the WebSphere MQ messaging provider at a specific scope.

To run the command, use the AdminTask object of the wsadmin scripting client.

This command is valid only when it is used with WAS v7 and later application servers. Do not use it with earlier versions.

For a list of the available WebSphere MQ messaging provider administrative commands, plus a brief description of each command, run at the wsadmin prompt:

print AdminTask.help('WMQAdminCommands')

For overview help on a given command, run at the wsadmin prompt:

print AdminTask.help('command_name')

After using the command, save changes to the master configuration. For example, use the following command:

AdminConfig.save()

Use the createWMQActivationSpec command to create a WebSphere MQ messaging provider activation specification at a specific scope.

We cannot create a WebSphere MQ messaging provider activation specification under either of the following conditions:

You create a CCDT based activation specification by specifying any of the following parameters:

If you do not specify any of the following parameters, you create a generic activation specification :


Target object

The scope of the WebSphere MQ messaging provider at which the WebSphere MQ messaging provider activation specification is to be created.



Required parameters

-name

The administrative name assigned to this WebSphere MQ messaging provider activation specification.

-jndiName

The name and location used to bind this object into WAS JNDI.

-destinationJndiName

The JNDI name of a WebSphere MQ messaging provider queue or topic type destination. When an MDB is deployed with this activation specification, messages for the MDB are consumed from this destination.

-destinationType

The type of the destination specified by using the -destinationJndiName parameter.

Enter one of the following values:

There is no default value.



Optional parameters

-description

An administrative description assigned to the activation specification.

-ccdtUrl

A URL to a client channel definition table to use, for this activation specification, when contacting WebSphere MQ.

Use this parameter to create ccdtURL activation specifications

Do not specify this parameter in conjunction with the following parameters: -qmgrName, -qmgrType, -qmgrHostname, -qmgrPortNumber, -qmgrSvrconnChannel, or -localAddress.

-ccdtQmgrName

A queue manager name, used to select one or more entries from a client channel definition table.

You must specify this parameter if the -transportType has been specified as client or bindingsThenClient.

Do not specify this parameter in conjunction with the following parameters: -qmgrName, -qmgrType, -qmgrHostname, -qmgrPortNumber, -qmgrSvrconnChannel, or -localAddress.

-qmgrName

The name of the queue manager to use, for this activation specification, when contacting WebSphere MQ.

Use this parameter to create generic activation specifications.

Do not specify this parameter in conjunction with the following parameters: -ccdtUrl or -ccdtQmgrName.

-wmqTransportType

This parameter determines the way in which a connection is established to WebSphere MQ for this activation specification.

Use this parameter to create generic activation specifications.

Enter one of the following case-sensitive values:

BINDINGS_THEN_CLIENT is the default value.

Do not specify this parameter in conjunction with the following parameters: -ccdtUrl or -ccdtQmgrName.

For more information about configuring a transport type of bindings then client or bindings, refer to Configure the WebSphere MQ messaging provider with native libraries information.

-qmgrHostname

The host name to use, for this activation specification, when attempting a client mode connection to WebSphere MQ. It must be a valid TCP/IP host name or IPv4 or IPv6 address.

The default value is the local host.

Do not specify this parameter in conjunction with the following parameters: -ccdtUrl or -ccdtQmgrName.

New feature: For information on setting the -qmgrHostname parameter in conjunction with the -connectionNameList parameter, see the description of the -connectionNameList parameter.

-qmgrPortNumber

The port number to use, for this activation specification, when attempting a client mode connection to WebSphere MQ.

Enter an integer value in the range 1 - 65536 (inclusive).

The default value is 1414.

Do not specify this parameter in conjunction with the following parameters: -ccdtUrl or -ccdtQmgrName.

New feature: For information on setting the -qmgrPortNumber parameter in conjunction with the -connectionNameList parameter, see the description of the -connectionNameList parameter.

-connectionNameList

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.

You must only use the -connectionNameList parameter to allow a connection to a multi-instance queue manager. Using the -connectionNameList parameter to connect to a non-multi-instance queue manager can jeopardize transaction integrity.

The -connectionNameList parameter must be entered as a comma separated list of host names and ports in the following format:

host(port),host(port)

For host enter a valid TCP/IP host name, IPv4 or IPv6 address.

For port enter an integer value between 1 and 65536 (inclusive). Specifying a value for port is optional. When you do not specify a value, port defaults to 1414.

For example: localhost(1234),remotehost(1234),remotehost2

When you specify the -connectionNameList parameter, the -qmgrHostname and -qmgrPortNumber parameters are automatically set to the host name and port number of the first entry in the connection name list. This overrides any values that you previously specified in the -qmgrHostname and -qmgrPortNumber parameters.

In the preceding example this would mean that -qmgrHostname would be localhost and -qmgrPortNumber would be 1234.

The -connectionNameList parameter is only valid for use in WAS v8.0.

Attempting to specify the -connectionNameList parameter on a WebSphere MQ messaging provider activation specification defined at a server or node scope that is running on a version of WAS earlier than v8.0 results in an error message when you run the following commands:

If you specify the -connectionNameList parameter on a cell or cluster-scoped WebSphere MQ activation specification, you can use it for nodes that are running WAS v7.0. The exact behaviour is determined by the fix pack level of the node:

You must not specify the -connectionNameList parameter in conjunction with the -ccdtUrl or -ccdtQmgrName parameters.

If you use the-connectionNameList parameter with a centrally managed SSL configuration the host name and port number information used to select the appropriate SSL configuration is based on the first entry in the -connectionNameList, regardless of which entry in the list is actually used to connect to the queue manager. This is because each instance of a multi-instance queue manager should be using the same SSL configuration, for a given server connection channel, regardless of which instance is actually running.

For more information on using multi-instance queue managers, see the WebSphere MQ information center.

-authAlias

The authentication alias used to obtain the credentials specified when this activation specification needs to establish a connection to WebSphere MQ.

-clientId

The client identifier used for connections started by using this activation specification.

where n is an integer greater than or equal to zero.

For example 6.0.0.0

-sslCrl

This parameter specifies a list of LDAP servers that are used to provide certificate revocation information if this activation specification establishes an SSL based connection to WebSphere MQ.

-sslResetCount

This parameter is used when the activation specification establishes an SSL connection to the queue manager. This parameter determines how many bytes to transfer before resetting the symmetric encryption key used for the SSL session.

Enter a value in the range 0 through 999,999,999.

The default value is 0.

-sslPeerName

-rcvExit

A comma-separated list of receive exit class names.

-rcvExitInitData

Initialization data to pass to the receive exit.

Do not specify this parameter unless you specify the -rcvExit parameter.

-sendExit

A comma-separated list of send exit class names.

-sendExitInitData

Initialization data to pass to the send exit.

Do not specify this parameter unless you specify the -sendExit parameter.

-secExit

A security exit class name.

-secExitInitData

Initialization data to pass to the security exit.

Do not specify this parameter unless you specify the -secExit parameter.

-compressHeaders

This parameter determines if message headers are compressed.

Enter one of the following values:

The default value is NONE.

-compressPayload

This parameter determines if message payloads are compressed.

Enter one of the following values:

The default value is NONE.

-msgRetention

This parameter determines if the connection consumer keeps unwanted messages on the input queue.

Enter one of the following values:

where YES specifies that the connection consumer keeps unwanted messages on the input queue, and NO specifies that the messages are disposed of according to their disposition options.

The default value is YES.

-rescanInterval

When a message consumer in the point-to-point domain uses a message selector to select which messages it is to receive, the JMS client searches the WebSphere MQ queue for suitable messages in the sequence determined by the MsgDeliverySequence attribute of the queue. When the client finds a suitable message and delivers it to the consumer, the client resumes the search for the next suitable message from its current position in the queue. The client continues to search the queue in this way until it reaches the end of the queue, or until the interval of time in milliseconds, as determined by the value of this -rescanInterval parameter has expired. In each case, the client returns to the beginning of the queue to continue its search, and a new time interval commences.

This parameter must be a positive integer value.

The default value is 5000.

-ccsid

The coded character set identifier (CCSID) to be used on connections.

The value of this parameter must be a positive integer and must be one of the CCSIDs supported by WebSphere MQ. See the WebSphere MQ messaging provider activation specification advanced properties for more details.

The default value is 819.

-failIfQuiescing

This parameter determines the behavior of certain calls to the queue manager when the queue manager is put into quiescing state.

The value of this parameter must be true or false.

true specifies that calls to certain methods fail if the queue manager is in a quiescing state. If an application detects that the queue manager is quiescing, the application can complete its immediate task and close the connection, allowing the queue manager to stop.

false specifies that no methods fail if the queue manager is in a quiescing state. If you specify this value, an application cannot detect that the queue manager is quiescing. The application might continue to perform operations against the queue manager, and therefore prevent the queue manager from stopping.

The default value is true.

-brokerCtrlQueue

The name of the broker control queue to use if this activation specification is to subscribe to a topic.

The default value is SYSTEM.BROKER.CONTROL.QUEUE.

-brokerSubQueue

The name of the queue to use for obtaining subscription messages if this activation specification is to subscribe to a topic.

The default value is SYSTEM.JMS.ND.SUBSCRIBER.QUEUE.

-sparseSubs

This parameter controls the message retrieval policy of a TopicSubscriber object.

The value of this parameter must be true or false

The default value is false.

-brokerQmgr

The name of the queue manager on which the broker is running.

-clonedSubs

This parameter determines whether two or more instances of the same durable topic subscriber can run simultaneously.

The value of this parameter must be ENABLED or DISABLED

The default value is DISABLED.

-qmgrSvrconnChannel

The value of this parameter must be either the empty string or a valid SQL 92 statement.

-poolTimeout

The period of time, in milliseconds, that an unused server session is held open in the server session pool before being closed due to inactivity.

The value of this parameter must be a positive integer.

The default value is 300,000.

-startTimeout

The period of time, in milliseconds, within which delivery of a message to an MDB must start after the work to deliver the message has been scheduled. If this period of time elapses, the message is rolled back onto the queue.

The value of this parameter must be a positive integer.

The default value is 10,000.

-subscriptionDurability

This parameter determines whether a durable or nondurable subscription is used to deliver messages to an MDB that is subscribing to the topic.

The value of this parameter must be Durable or Nondurable

The default value is Nondurable.

-subscriptionName

The name of the durable subscription.

-customProperties

This parameter specifies custom properties to be passed to the WebSphere MQ messaging provider activation specification implementation. Typically, custom properties are used to set attributes of the activation specification which are not directly supported through the WebSphere administration interfaces.

Each custom property is specified using name and value table step parameters. Since these are table steps, the order of the two parameters is fixed, so always specify the name first and the value second:

For example, -WAS_EndpointInitialState is a custom property that can be used with the -customProperties parameter. The value of -WAS_EndpointInitialState must be ACTIVE or INACTIVE. -WAS_EndpointInitialState determines whether the endpoint is activated when the endpoint is registered. If the parameter is set to active, 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.

This parameter should be ignored for subsequent activation or deactivation via the J2CMessageEndpoint MBean.

-localAddress

This parameter specifies either or both of the following:

Do not specify this parameter in conjunction with the following parameters: -ccdtUrl or -ccdtQmgrName.

-sslType

This parameter determines the configuration, if any, to use when applying SSL encryption to the network connection to the queue manager.

The value of this parameter must be CENTRAL, SPECIFIC or NONE

The -sslConfiguration parameter is not valid unless this parameter is set to SPECIFIC.

The default value is NONE.

-sslConfiguration

The name of the SSL configuration to use when using SSL to secure network connections to the queue manager.

Do not specify this parameter unless the parameter -sslType is assigned the value SPECIFIC.

The value of this parameter must correspond to an SSL configuration.

There is no default value.

-stopEndpointIfDeliveryFails

This parameter indicates whether the endpoint should be stopped if message delivery fails the number of times specified by the failureDeliveryCount property.

The value of this parameter must be true or false.

The default value is true.

-failureDeliveryCount

This parameter specifies the number of sequential delivery failures that are allowed before the endpoint is suspended. This value is only used if stopEndpointIfDeliveryFails is true.

The value of this parameter must be a non-negative integer.

The default value is 0, which means that the endpoint is stopped the first time it fails.


Example

In the following examples, code blocks beginning with wsadmin> show code that is entered by the user. Lines that do not begin with wsadmin> show code that has been returned by the console.

The following example creates an activation specification, specifying the minimum number of parameters. Due to the default values assumed for the unspecified parameters, MDBs deployed by using this activation specification are co-located with a generic queue manager installed on the same node.


Example

The following example creates an activation specification for which the user must specify and maintain all the parameters used for establishing a connection to WebSphere MQ.


Example

The following example creates an activation specification that uses a CCDT to locate the queue manager to connect to.
