To prepare your system for chunking, ensure that a UNIQUE_ID property is
defined.
About this task
The content federation exporter uses the UNIQUE_ID property to perform chunking. For some
repositories, the UNIQUE_ID property is predefined. If it is not already defined, edit the data map
to identify a property in the data map as the UNIQUE_ID property.
Procedure
To prepare your system for chunking:
- Open the IBM® Content Integrator Administration tool.
- Choose an existing data map from the Configuration Data tree or create a new data map.
- Review the list of available elements. If an existing element
has unique values, it can be used as the UNIQUE_ID property. If there
is not a suitable element, create a new element. You can use any name
for this element.
- From the property list, select the unique repository property that you want to use. Make sure
that this property supports the greater than or equal to (>=) operator and the less than (<)
operator, can be queried, and is selectable.
- Click Property Description to open the Property
Description window.
- Set the value of the Extended Data Type field to
UNIQUE_ID.
- If you add an element to the property map, complete the rest of the fields in the
Property Description window.
- Save your settings.
- Restart the IBM Content Integrator VeniceBridgeServices
process.
- Restart the content federation exporter.
