WebSphere MQ queue settings (MQ Config)

 

To view or change the configuration properties defined to WebSphere MQ for the selected queue destination:

Console | Resources | WebSphere MQ JMS Provider | WebSphere MQ Queue Destinations | destination_name | MQ Config

To view this screen, you need to have first started the MQ command server by running...

strmqcsv queue_mgr

This screen, and the Listener Ports screen, are useful for determining if WAS is communicating with MQ.

A queue destination is used to configure the properties of a JMS queue. A queue for use with the WebSphere MQ JMS provider has the following extra properties defined to WebSphere MQ.

Some properties displayed are read-only and cannot be changed.

These MQ Config properties can be used only to view or change the properties of local queues. You cannot use MQ Config to administer alias or remote queues.

To be able to view or change properties, the WebSphere MQ Queue Manager on which the queue resides must be configured for remote administration and be running.

The property values that you specify must match the values that you specified when configuring WebSphere MQ JMS resources.

Base queue name The name of the local queue to which messages are sent, on the queue manager specified by the Base queue manager name property.

Data type String

Base queue manager name The name of the WebSphere MQ queue manager to which messages are sent.

This queue manager provides the queue specified by the Base queue name property.

Data type String

Queue manager host The name of host for the queue manager on which the queue destination is created.

Data type String

Queue manager port The number of the port used by the queue manager on which this queue is defined.

Data type Integer
Range A valid TCP/IP port number. This port must be configured on the WebSphere MQ queue manager.

Server connection channel name The name of the channel used for connection to the WebSphere MQ queue manager.

Data type String
Range 1 through 20 ASCII characters

User ID The user ID used, with the Password property, for authentication when connecting to the queue manager to define the queue destination.

If you specify a value for the User name property, also specify a value for the Password property.

Data type String

Password The password, used with the User name property, for authentication when connecting to the queue manager to define the queue destination.

If you specify a value for the User name property, also specify a value for the Password property.

Data type String

Name The name of the queue defined to the WebSphere MQ queue manager.

Data type String
Range 1 through 48 ASCII characters.

Description The WebSphere MQ queue description, for administrative purposes within WebSphere MQ.

Data type String
Default Null
Range 1 through 64 ASCII characters.

Inhibit Put Whether or not put operations are allowed for this queue.

Data type Enum
Units Not applicable
Default Cleared
Range

Allowed Put operations are allowed for this queue.

Not allowed Put operations are not allowed for this queue.

Persistence Whether all messages sent to the destination are persistent, non-persistent, or have their persistence defined by the application

Data type Enum
Units Not applicable
Default APPLICATION_DEFINED
Range

Application defined Messages on the destination have their persistence defined by the application that put them onto the queue.

Queue defined [WebSphere MQ destination only] Messages on the destination have their persistence defined by the WebSphere MQ queue definition properties.

Persistent Messages on the destination are persistent.

Non persistent Messages on the destination are not persistent.

Cluster name The name of the cluster to which the WebSphere MQ queue manager belongs.

If you specify a value for Cluster name, you cannot specify a value for Cluster name list. Cluster names must conform to the rules described in the WebSphere MQ MQSC Command Reference book.

Data type String
Default Null
Range A valid WebSphere MQ name for a queue manager cluster, as 1 through 48 ASCII characters

Cluster name list The name of the cluster namelist to which the WebSphere MQ queue manager belongs.

If you specify a value for Cluster name, you cannot specify a value for Cluster name list.

Data type String
Default Null
Range A valid WebSphere MQ name for a list of queue manager clusters, as 1 through 48 ASCII characters

Default Binding The default binding to be used when the queue is defined as a cluster queue.

Data type Enum
Default Null
Range A

On open The queue handle is bound to a specific instance of the cluster queue when the queue is opened.

Not fixed The queue handle is not bound to any particular instance of the cluster queue. This allows the queue manager to select a specific queue instance when the message is put, and to change that selection subsequently should the need arise.

Inhibit Get Whether or not get operations are allowed for this queue.

Data type Enum
Units Not applicable
Default Cleared
Range

Allowed Get operations are allowed for this queue.

Not allowed Get operations are not allowed for this queue.

Maximum queue depth The maximum number of messages allowed on the queue.

Data type Integer
Units Messages
Default
Range A value greater than or equal to zero, and less than or equal to...

  • 999 999 999 if the queue is on OS/390

  • 640 000 if the queue is on any other WebSphere MQ platform

For more information about the maximum value allowed, see WebSphere MQ MQSC Command Reference.

If this value is reduced, any message that is already on the queue are not affected, even if the number of messages exceeds the new maximum.

Maximum Message Length The maximum length, in bytes, of messages on this queue.

Data type Integer
Units Bytes
Default
Range A value greater than or equal to zero, and less than or equal to the maximum message length for the queue manager and WebSphere MQ platform. For more information about the maximum value allowed, see WebSphere MQ MQSC Command Reference.

If this value is reduced, any message that is already on the queue are not affected, even if the message length exceeds the new maximum.

Shareability Whether multiple applications can get messages from this queue.

Data type Enum
Units Not applicable
Default Not shareable
Range

Not shareable Only one application instance can get messages from the queue.

Shareable More than one application instance can get messages from the queue.

Input Open Option The default share option for applications opening this queue for input

Data type Enum
Units Not applicable
Default Cleared
Range

Exclusive The open request is for exclusive input from the queue.

Shared The open request is for shared input from the queue.

Message Delivery Sequence The order in which messages are delivered from the queue in response to get requests.

Data type Enum
Units Not applicable
Default Priority
Range

Priority Messages are delivered in first-in-first-out (FIFO) order within priority. This is the default supplied with WebSphere MQ, but your installation might have changed it.

FIFO Messages are delivered in FIFO order. Priority is ignored for messages on this queue.

Backout threshold The maximum number of times that a message can be backed out. If this threshold is reached, the message is requeued on the backout queue specified by the Backout Requeue name property.

The WebSphere MQ queue manager keeps a record of the number of times that each message has been backed out. When this number reaches a configurable threshold, the connection consumer requeues the message on a named backout queue. If this requeue fails for any reason, the message is removed from the queue and either requeued to the dead-letter queue, or discarded.

Data type Integer
Default 0
Range

0 Never requeue messages

1 or more The number of times that a message has been backed, at which the message is requeued on a named backout queue.

Backout Requeue name The name of the backout queue to which messages are requeued if they have been backed out more than the backout threshold.

The WebSphere MQ queue manager keeps a record of the number of times that each message has been backed out. When this number reaches a configurable threshold, the connection consumer requeues the message on a named backout queue. If this requeue fails for any reason, the message is removed from the queue and either requeued to the dead-letter queue, or discarded.

Data type String
Default Null
Range 1 through 48 characters.

Harden Get Backout Whether hardening should be used to ensure that the count of the number of times that a message has been backed out is accurate.

Data type Enum
Units Not applicable
Default Cleared
Range

Not hardened The count is not hardened. This is the default supplied with WebSphere MQ, but your installation might have changed it.
