If it is set to true, the values of the -integerEncoding, -decimalEncoding, and -floatingPointEncoding attributes are ignored.

If it is set to false, the encoding is specified by the -integerEncoding, -decimalEncoding, and -floatingPointEncoding attributes.

-integerEncoding

The integer encoding setting for this queue.

Enter one of the following case-sensitive values: Normal, Reversed.

Normal is the default value.

-decimalEncoding

-useRFH2

This parameter determines whether an RFH version 2 header is appended to messages sent to this destination, also know as targetClient..

Enter one of the following case-sensitive values: true, or false (equivalent to JMS or MQ targetClient, respectively).

The default value is true (JMS targetClient).

-sendAsync

This parameter determines whether messages can be sent to this destination without the queue manager acknowledging that they have arrived.

Enter one of the following case-sensitive values: YES, NO, or TDEF.

The default value is TDEF.

-readAhead

This parameter determines whether messages for non-persistent consumers can be read ahead and cached.

Enter one of the following case-sensitive values: YES, NO, or TDEF.

The default value is TDEF.

-readAheadClose

This property determines the behavior that occurs when you close a message consumer that is receiving messages asynchronously by using a message listener from a destination that has the readAhead parameter set to True.

When a value of deliverAll is specified, all read-ahead messages are delivered before the consumer is closed.

When a value of deliverCurrent is specified, only in-progress messages are delivered before the consumer is closed.

The default value is deliverCurrent.

-wildcardFormat

This parameter determines which sets of characters are interpreted as topic wildcards.

Valid values are Topic or Char.

The default value is Topic.

-brokerDurSubQueue

The name of the queue, which is defined to the queue manager, from which a connection consumer receives non-durable subscription messages.

The value of this parameter must be either blank or a valid queue name.

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

-brokerCCDurSubQueue

The name of the queue, which is defined to the queue manager, from which a connection consumer receives durable subscription messages.

The value of this parameter must be either blank or a valid queue name.

The default value is SYSTEM.JMS.D.CC.SUBSCRIBER.QUEUE.

-brokerPubQueue

The name of the queue, which is defined to the queue manager, to which publication messages are sent.

The value of this parameter must be either blank or a valid queue name.

The default value is SYSTEM.BROKER.DEFAULT.STREAM.

-brokerPubQmgr

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

The value of this parameter must be a valid queue manager name or remain blank.

There is no default value.

-brokerVersion

This parameter determines the level of functionality that is required for publish/subscribe operations.

The value of this parameter must be V1 or V2.

The default value is V1.

-customProperties

This parameter specifies custom properties to be passed to the WebSphere MQ messaging provider topic type destination implementation. Typically, custom properties are used to set attributes of the topic type destination that 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 you must always specify the name first and the value second:

• In Jython: [name value]
• In Jacl: {name value}
