Work with WebSphere MQ topic properties files

We can use properties files to create or change WebSphere MQ topic properties.

Determine the changes to make to your WebSphere MQ topic configuration.

Start the wsadmin scripting tool. To start wsadmin using the Jython language, run the wsadmin -lang Jython command from the bin directory of the server profile. Using a properties file, we can create, modify, or delete a WebSphere MQ topic object and its configuration properties.

Run administrative commands using wsadmin to create or change a properties file for a WebSphere MQ topic, validate the properties, and apply them to your configuration.

Actions for WebSphere MQ topic properties files. We can create, modify, and delete WebSphere MQ topic configuration properties.

Action	Procedure
create	Set properties and then run the applyConfigProperties command.
modify	Edit properties and then run the applyConfigProperties command.
delete	Uncomment #DELETE=true and run the deleteConfigProperties command.

Optionally, we can use interactive mode with the commands:

AdminTask.command_name('-interactive')

• Create a WebSphere MQ topic and its properties.

  1. Create a properties file for an MQTopic object.

     Open an editor and create an MQ topic properties file. We can copy the example properties file in this step into an editor and modify the properties as needed for the situation.

     An example properties file for an MQTopic object with a JNDI name of topicJndiName under a JMSProvider named WebSphere MQ JMS Provider at the cell scope follows:

     #
     # Header
     #
     ResourceType=MQTopic
     ImplementingResourceType=GenericType
     ResourceId=Cell=!{cellName}:JMSProvider=WebSphere MQ JMS Provider:MQTopic=jndiName#topicJndiName
     #DELETE=true
     #
     #Properties
     #
     wildcardFormat=topicWildcards #ENUM(characterWildcards|allWildcards|topicWildcards),default(topicWildcards)
     readAhead=YES #ENUM(QUEUE_DEFINED|YES|NO),default(YES)
     specifiedExpiry=0 #long,default(0)
     baseTopicName=topicBaseTopicName #required
     brokerPubQmgr=null
     providerType=null #readonly
     decimalEncoding=Normal #ENUM(Normal|Reversed),default(Normal)
     expiry=APPLICATION_DEFINED #ENUM(APPLICATION_DEFINED|SPECIFIED|UNLIMITED),default(APPLICATION_DEFINED)
     sendAsync=YES #ENUM(QUEUE_DEFINED|YES|NO),default(YES)
     integerEncoding=Normal #ENUM(Normal|Reversed),default(Normal)
     brokerPubQueue=null
     specifiedPriority=0 #integer,default(0)
     jndiName=topicJndiName #required
     CCSID=0 #integer,default(0)
     category=null
     description=null
     brokerVersion=V1 #ENUM(V2|V1),default(V1)
     brokerCCDurSubQueue=null
     brokerDurSubQueue=null
     boolean=null
     targetClient=JMS #ENUM(JMS|MQ),default(JMS)
     priority=APPLICATION_DEFINED #ENUM(APPLICATION_DEFINED|SPECIFIED|QUEUE_DEFINED),default(APPLICATION_DEFINED)
     provider=WebSphere MQ JMS Provider #ObjectName(JMSProvider),readonly
     persistence=APPLICATION_DEFINED #ENUM(APPLICATION_DEFINED|HIGH|NONPERSISTENT|PERSISTENT|QUEUE_DEFINED),default(APPLICATION_DEFINED)
     floatingPointEncoding=IEEENormal #ENUM(IEEENormal|IEEEReversed|S390),default(IEEENormal)
     readAheadClose=DELIVERALL #ENUM(DELIVERCURRENT|DELIVERALL),default(DELIVERALL)
     multicast=AS_CF #ENUM(AS_CF|DISABLED|NOT_RELIABLE|RELIABLE|ENABLED),default(AS_CF)
     name=topicName #required 
     
     EnvironmentVariablesSection
     #
     #
     #Environment Variables
     cellName=WASCell06

  2. Run the applyConfigProperties command to create an MQTopic configuration.

     Running the applyConfigProperties command applies the properties file to the configuration. In this Jython example, the optional -reportFileName parameter produces a report named report.txt:

     AdminTask.applyConfigProperties(['-propertiesFileName myObjectType.props -reportFileName report.txt '])

• Modify an existing WebSphere MQ topic.
  1. Obtain a properties file for the WebSphere MQ topic to change.

     We can extract a properties file for an MQTopic using the extractConfigProperties command.

  2. Open the properties file in an editor and change the properties as needed.

     Ensure the environment variables in the properties file match your system.

  3. Run the applyConfigProperties command to change a WebSphere MQ topic configuration.

• If we no longer need a WebSphere MQ topic, we can delete the entire WebSphere MQ topic object.

  To delete the entire object, specify DELETE=true in the header section of the properties file and run the deleteConfigProperties command; for example:

  AdminTask.deleteConfigProperties('[-propertiesFileName myObjectType.props -reportFileName report.txt]')

Results

We can use the properties file to manage the WebSphere MQ topic object.

Save the changes to your configuration.
