createSIBJMSQueue command

Use the createSIBJMSQueue command to create a new JMS queue for the default messaging provider at a specific scope.

Para executar o comando, utilize o objeto AdminTask do cliente de script wsadmin.

[IBM i][IBM i]O cliente de script wsadmin é executado do Qshell. [IBM i]Para obter informações adicionais, consulte Configurando o Qshell para Executar Scripts do WebSphere Usando o Script wsadmin.

A ajuda da linha de comandos é fornecida para comandos do barramento de integração de serviços:
  • Para obter uma lista dos comandos JMS do barramento de integração de serviços disponíveis no Jython e uma breve descrição de cada comando, digite o seguinte comando no prompt wsadmin:

Purpose

The createSIBJMSQueue command creates a JMS queue for the default messaging provider at a specific scope.

Target object

The scope of the default messaging provider at which the JMS queue is to be created.

Required parameters

-name
The identifier by which this JMS queue is known for administrative purposes.
-jndiName
The JNDI name that is used to bind the queue into the application server namespace.
-queueName
The name of the service integration bus destination to which the JMS queue maps.

Optional parameters

-description
An optional description for the bus, for administrative purposes.
-deliveryMode Application | NonPersistent | Persistent
The delivery mode to be used by MessageProducers for messages sent to this queue.
-timeToLive
The default length of time from its dispatch time that a message sent to this queue should be retained by the system, where 0 indicates that time to live value does not expire. The value from the producer is used if the Time to Live parameter is not supplied.
-priority
The priority for messages sent to this queue. The value from the producer is used if not completed. In the range 0 to 9 where 0 is the lowest priority and 9 is the highest priority
-readAhead AsConnection | AlwaysOn | AlwaysOff
Used to control read-ahead optimization during message delivery. The default is AsConnection.
-busName
The name of the service integration bus that the service integration bus destination, identified by queueName, is configured on. If not set, the bus that the application is connected to is used.
-scopeToLocalQP TRUE | FALSE
Indicates whether the underlying service integration bus queue destination is scoped to a local queue point when addressed using this JMS queue. A local queue point is a queue point that is configured on the messaging engine to which the JMS application is connected. The option applies when using this JMS queue to send and receive messages and when setting a reply queue in a request message. When a reply queue is set in a request message, the local queue point is on the messaging engine to which the application setting the reply queue is connected, not the messaging engine to which the application that uses the reply queue sends the reply message. If the connected messaging engine does not have a queue point for the destination this option is ignored. The default value is FALSE.

Changing the default setting of this option is supported only when used by a JMS application that is running with a WebSphere® Application Server Versão 7.0 ou posterior server or client, and that is connected to a messaging engine running on a WebSphere Application Server Versão 7.0 ou posterior server. Use on previous versions of WebSphere Application Server will result in an exception to the application.

-producerBind TRUE | FALSE
Indicates how JMS producers bind to queue points of the clustered queue. The default value is FALSE.

Changing the default setting of this option is supported only when used by a JMS application that is running with a WebSphere Application Server Versão 7.0 ou posterior server or client, and that is connected to a messaging engine running on a WebSphere Application Server Versão 7.0 ou posterior server. Use on previous versions of WebSphere Application Server will result in an exception to the application.

TRUE
The messaging system selects a queue point when the session is opened. All messages produced by the session are sent to the chosen queue point. The messaging system uses the producerPreferLocal setting when selecting the queue point.
FALSE
The messaging system selects a queue point each time a message is sent, potentially workload balancing the messages across all available queue points. The messaging system uses the producerPreferLocal setting when selecting the queue point.
-producerPreferLocal TRUE | FALSE
Indicates whether a queue point local to the producer is preferred to other available queue points when the messaging system selects a queue point to produce messages to. A local queue point is a queue point that is configured on the messaging engine to which the JMS application is connected. The default value is TRUE.

Changing the default setting of this option is supported only when used by a JMS application that is running with a WebSphere Application Server Versão 7.0 ou posterior server or client, and that is connected to a messaging engine running on a WebSphere Application Server Versão 7.0 ou posterior server. Use on previous versions of WebSphere Application Server will result in an exception to the application.

-consumerGatherMessages TRUE | FALSE
A JMS consumer or browser is attached to a single queue point of the service integration bus destination by the messaging system. This parameter indicates whether a JMS consumer or browser take messages from any available queue points of the service integration bus destination (TRUE), or the single queue point to which it is attached (FALSE). The default value is FALSE. Gathering messages from multiple queue points results in an increased performance cost and message order cannot be maintained.

Changing the default setting of this option is supported only when used by a JMS application that is running with a WebSphere Application Server Versão 7.0 ou posterior server or client, and that is connected to a messaging engine running on a WebSphere Application Server Versão 7.0 ou posterior server. Use on previous versions of WebSphere Application Server will result in an exception to the application.

  • Using Jython:
    wsadmin>AdminConfig.getid("/Node:9994GKCNode01" )
    '9994GKCNode01(cells/9994GKCNode01Cell/nodes/9994GKCNode01|node.xml#Node_1)'
    wsadmin>AdminTask.createSIBJMSQueue("WASINSTALL2Node01(cells/WASINSTALL2Cell01/

The following example shows how to create a default messaging provider JMS queue that selects a queue point when a session is opened and never changes:
  • Using Jython:
    wsadmin>AdminTask.createSIBJMSQueue("9994GKCNode01(cells/9994GKCNode01Cell/
    nodes/9994GKCNode01|node.xml#Node_1)", ["-name", "MyJMSQueue", "-jndiName",
     "MyJMSQueue", "-busName bus1", "-queueName", "MyExistingQueue", "-deliveryMode",
     "Application", "-readAhead", "AsConnection", "-producerBind", "TRUE"])
  • Using Jacl:
    wsadmin>$AdminTask createSIBJMSQueue 9994GKCNode01(cells/9994GKCNode01Cell/
    nodes/9994GKCNode01|node.xml#Node_1 {-name MyJMSQueue -jndiName MyJMSQueue 
    -busName bus1 -queueName MyExistingQueue -deliveryMode Application 
    -readAhead AsConnection -producerBind TRUE }
The following example shows how to create a default messaging provider JMS queue that selects a queue point every time a message is sent. There is no preference over which queue point is selected and the consumers take messages from any queue point:
  • Using Jython:
    wsadmin>AdminTask.createSIBJMSQueue("9994GKCNode01(cells/9994GKCNode01Cell/
    nodes/9994GKCNode01|node.xml#Node_1)", ["-name", "MyJMSQueue", "-jndiName",
     "MyJMSQueue", "-busName bus1", "-queueName", "MyExistingQueue", "-deliveryMode",
     "Application", "-readAhead", "AsConnection", "-producerBind", "FALSE",
     "-producerPreferLocal", "FALSE", "-gatherMessages", "TRUE"])
  • Using Jacl:
    wsadmin>$AdminTask createSIBJMSQueue 9994GKCNode01(cells/9994GKCNode01Cell/
    nodes/9994GKCNode01|node.xml#Node_1 {-name MyJMSQueue -jndiName MyJMSQueue 
    -busName bus1 -queueName MyExistingQueue -deliveryMode Application 
    -readAhead AsConnection -producerBind FALSE -producerPreferLocal FALSE 
    -gatherMessages TRUE}
The following example shows how to create a default messaging provider JMS queue that scopes all operations on it down to the queue point local to the user of the JMS queue:
  • Using Jython:
    wsadmin>AdminTask.createSIBJMSQueue("9994GKCNode01(cells/9994GKCNode01Cell/
    nodes/9994GKCNode01|node.xml#Node_1)", ["-name", "MyJMSQueue", "-jndiName",
     "MyJMSQueue", "-busName bus1", "-queueName", "MyExistingQueue", "-deliveryMode",
     "Application", "-readAhead", "AsConnection", "-scopeToLocalQP", "TRUE"])
  • Using Jacl:
    wsadmin>$AdminTask createSIBJMSQueue 9994GKCNode01(cells/9994GKCNode01Cell/
    nodes/9994GKCNode01|node.xml#Node_1 {-name MyJMSQueue -jndiName MyJMSQueue
