Each publisher has to be configured to connect to external systems. Double-click the number next to a given publisher to open the configuration.
Sample publisher configurations can be found in MDM Example Project project in your build. |
If publishing of an event fails for any publisher, the publishing is stopped. When resumed, the event at which the failure occurred is published again by all publishers (that means some publishers might have distributed it multiple times). The preceding events are not published again. |
Event JMS publisher
This publisher sends the events through Java Message Service (for more information, see Oracle JMS article.
To run this publisher, the JMS server component must first be configured in the MDM runtimeConfig .
For more information, see Server Configuration for MDM Web App.
|
To configure the event JMS publisher:
-
Create a new event handler as described in Processors.
-
Switch to the Publishers tab, select Add and then Event JMS Publisher.

Destination - Target JMS queue or topic destination.
A destination is the object a client uses to specify the target of messages it produces and the source of messages it consumes.
In the PTP messaging domain, destinations are called queues. In the pub/sub messaging domain, destinations are called topics.
A JMS application can use multiple queues or topics (or both).

Traversing plan publisher
The traversing plan publisher is an extension to the event plan publisher. It ensures that all related records defined by the model are present in the plan.
The configuration requires defining a root entity and related entities. Master entity-based roots can have both other master and instance entities as related entities. Instance entity-based roots can have other instance entities as related entities.
When an event containing one or more entities from the defined model is sent to the publisher, the adapter traverses through all the relationships between the entities, retrieves their data, and provides them to the plan to their corresponding Integration Inputs.
The traversing plan publisher is called by the processor for each group of related records that will always contain at least one record that had some change event. The record group is always consistent and complete based on the defined publisher model configuration (that is usually a subset of the MDM hub model).
To configure the traversing publisher:
-
Create a new event handler as described in Processors.
-
Switch to the Publishers tab, select Add and then Traversing Plan Publisher.
-
Double-click the row number of the publisher to see the configuration details.
-
Configure the settings:
-
Enable (Boolean) - Select this to enable the publisher.
-
Description (optional) - Description of the publisher.
-
Name (optional) - Attribute that is used to differentiate between several plan publishers with the same layer name and entity.
-
Root Entity - Press Ctrl+Space to see a list of the root entities. The root entity should be the top-level parent in the data tree that is sent to the plan. It is the entity for which the related entities are configured and the data retrieved.
For better plan name readability, use underscore at the beginning of the suffix. -
All Columns (Boolean) - If enabled, events for all columns in the selected entity are published.
If All Columns is selected, including meta columns and entity columns in this section returns an error. -
Meta Columns - Define the metadata columns that are provided in the publishing plan.
-
Entity Columns - Define the entity columns that are provided in the publishing plan. Old Value (Boolean) - If enabled, the original values for those columns are sent to the plan. Actual Value (Boolean) - If enabled, the current values for those columns are sent to the plan. Related Entities - Choose the related entities you want to include in the publisher (only child entities of the defined root entity can be chosen). The depth of relations is dependent on your model.
