Creating and modifying publications

In Classic event publishing, a publication associates a source table or view with a WebSphere® MQ message queue. Messages that describe changes to source data are put on that message queue. Applications that need to be aware of the changes can read the messages from the message queue.

Before you begin

About this task

The source table or view maps to a data source such as Adabas, CA-IDMS, CICS® VSAM, IMS™, or native VSAM. When a change occurs to the data that is mapped to the source table or view, Classic event publishing captures the change, converts it to a message, and puts the message on the message queue, called a send queue.

Publications are used only in Classic event publishing. They are not used in Classic replication.

Procedure

To create a publication:

  1. In Classic Data Architect, open the New Publication wizard. In the Database Explorer, right-click the Publications folder for the data server that you want to create the publication in. Select New Publication.
  2. In the New Publication wizard, provide the following information:
    • The name of the publication
    • The schema and name of the table or view that you want to use as the source for the publication
    • The WebSphere MQ name of the message queue to use as the send queue to transport messages for the publication. The publication queue map that you select determines whether the messages for the publication will be in XML, XML with a Java™ Message Service (JMS) topic, or a delimited format.
    • If you are publishing to JMS applications, the topic that you want to send in the messages for the publication
    • Whether to publish the before values in addition to the after values for a data event
    • For every row-level change, whether to publish values in changed columns only or publish the values for all columns in the row
  3. Click Finish to create the publication.
The publication appears in the Publications folder. If the corresponding correlation service is running, right-click the publication and select Activate to start publishing messages.

If you want to change the properties of the publication, right-click the publication and select Update.
