createWMQTopic command
Use the createWMQTopic command to create a JMS topic destination 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 createWMQTopic command to create a WebSphere MQ messaging provider topic type destination at a specific scope.
We cannot create a WebSphere MQ messaging provider topic type destination under either of the following conditions:
- A WebSphere MQ messaging provider topic type destination already exists with the same name, at the same scope.
- The JNDI name clashes with another entry in WAS JNDI.
Target object
The scope of the WebSphere MQ messaging provider at which the WebSphere MQ messaging provider topic type destination is to be created.
Required parameters
-name
The administrative name assigned to this WebSphere MQ messaging provider topic type destination.
-jndiName
The name used to bind this object into WAS JNDI.
-topicName
The name of the WebSphere MQ topic where publications are received from, or sent to, when this destination definition is used.
Optional parameters
-description
An administrative description assigned to the topic type destination.
-persistence
This parameter determines the level of persistence used to store messages sent to this destination. Enter one of the following case-sensitive values:
- APP
- TDEF
- PERS
- NON
- HIGHT
APP is the default value.
-priority
The priority level to assign to messages sent to this destination. Enter one of the following case-sensitive values:
- APP
- TDEF
or enter a positive integer in the range 0 to 9 (inclusive).
The default value is APP .
-expiry
The length of time after which messages that are sent to this destination expire and are dealt with according to their disposition options. Enter one of the following case-sensitive values:
- APP
- UNLIM
or enter any positive integer.
The default value is APP.
-ccsid
The coded character set identifier (CCSID). The value of this parameter must be a positive integer or blank. See the WebSphere MQ messaging provider queue and topic advanced properties settings for more details.
The default value is 1208.
Leaving this field empty indicates that the default value must be used.
-useNativeEncoding
This parameter specifies whether to use native encoding or not. It can take a value true or false. 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
The decimal encoding setting for this queue. Enter one of the following case-sensitive values: Normal, Reversed.
The default value is Normal.
-floatingPointEncoding
The floating point encoding setting for this queue. Enter one of the following case-sensitive values: IEEENormal, IEEEReversed, z/OS
The default value is IEEENormal.
-useRFH2
This parameter determines whether an RFH version 2 header is appended to messages sent to this destination. Enter one of the following case-sensitive values: true or false.
The default value is true.
-sendAsync
This parameter determines whether messages can be sent to this destination without queue manager acknowledging that they have arrived. Enter one of the following case-sensitive values: YES, NO or TDEF.
The default value is YES.
-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 YES.
-readAheadClose
This property determines the behavior that occurs when closing 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 closing the consumer.
When a value of deliverCurrent is specified, only in-progress messages are delivered before closing the consumer.
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, defined to the queue manager, from which a connection consumer receives non-durable subscription messages. The value of this parameter must be a valid queue name or left blank
The default value is SYSTEM.JMS.D.SUBSCRIBER.QUEUE.
-brokerCCDurSubQueue
The name of the queue, defined to the queue manager, from which a connection consumer receives durable subscription messages. The value of this parameter must be a valid queue name or left blank
The default value is SYSTEM.JMS.D.CC.SUBSCRIBER.QUEUE.
-brokerPubQueue
The name of the queue, defined to the queue manager, to which publication messages are sent. The value of this parameter must be a valid queue name or left blank
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 left blank
There is no default value.
-brokerVersion
This parameter determines the level of functionality 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 always specify the name first and the value second:
- In Jython: [name]
- In Jacl: {name}
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 a topic definition by specifying the minimum number of parameters.
