If appropriate, in the content pane, change the scope of the WebSphere MQ messaging provider.
If the scope is set to node or server scope for a Version 5 node, the console presents the subset of resources and properties that are applicable to WAS V5.

MQ Config

A WebSphere MQ 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.
Notes:
To browse or change these MQ Config properties, the WebSphere MQ Queue Manager on which the queue resides must be configured for remote administration and be running. You must also have installed the WebSphere MQ client. If you have not done this, the console displays messages like the following:
The WMQQueueDefiner MBean has encountered an error. WMSG0331E: The MQ Client is required for this functionality, but it is not installed.
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.

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

The property values specified must match the values specified when configuring WebSphere MQ JMS resources. For more information about configuring WebSphere MQ JMS resources, see the book...

In WebSphere MQ, names can have a maximum of 48 characters, with the exception of channels which have a maximum of 20 characters.
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 ID property, also specify a value for the Password property.

Data type String

Password

The password, used with the User ID property, for authentication when connecting to the queue manager to define the queue destination.
If you specify a value for the User ID property, also specify a value for the Password property.

Data type String

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
Default Put Inhibited
Range

Put Allowed

Put operations are allowed for this queue.

Put Inhibited

Put operations are not allowed for this queue.

Persistence

Whether messages on the queue are persistent or non-persistent.

Data type Enum
Default Persistent
Range

Persistent

Messages on the queue are persistent.

Non persistent

Messages on the queue 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 should not 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 should not 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 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 On Open
Range

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
Default Get Inhibited
Range

Get Inhibited

Get operations are not allowed for this queue.

Get Allowed

Get operations are allowed for this queue.

Maximum Queue Depth

The maximum number of messages allowed on the queue.

Data type Integer
Units Number of messages
Default 0
Range
A value greater than or equal to zero, and less than or equal to 640 000.
For more information about the maximum value allowed, see the WebSphere MQ MQSC Command Reference.
If this value is reduced, any messages that are 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 Number of bytes
Default 0
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 the 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
Default Shareable
Range

Shareable

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

Not Shareable

Only 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
Default Exclusive
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
Default FIFO
Range

FIFO

Messages are delivered in first in first out (FIFO) order. Priority is ignored for messages on this queue.

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.

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
Default Hardened
Range

Hardened

The count is hardened.

Not Hardened

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

Range 0 (lowest priority) through 9 (highest priority)
