Introduction to Db2 for LUW CDC Connector

You can use Db2 for LUW CDC Connector to connect to a PowerExchange CDC environment to retrieve change records that PowerExchange captures in near real time for Db2 for Linux, UNIX, and Windows (LUW) source tables.
Db2 for LUW CDC Connector extracts change records from PowerExchange Logger log files and sends the change records to Data Integration. Data Integration can then transmit the change records to a supported target.
When you define mappings in Data Integration, you select the extraction maps that PowerExchange generated for Db2 for LUW source tables when you registered the tables.. The CDC Connector metadata adapter can then retrieve the source metadata from the extraction maps and store this information in the cloud.
To extract source change records from PowerExchange Logger log files, you must run the mapping tasks that are associated with the mappings. A mapping task runs to the end-of-log (EOL) in the PowerExchange Logger log files and then stops. You can manually restart the mapping task from a specific point in the logs or create a schedule that runs the mapping task on a recurring basis. If the mapping task fails, Db2 for LUW CDC Connector can resume processing from the point of interruption based on recovery information that is stored on the target.
Db2 for LUW CDC Connector must be able to connect to an active PowerExchange CDC environment that includes the PowerExchange Logger. You do not need to copy the PowerExchange dbmover configuration file or PowerExchange Logger pwxccl configuration file to the connector system. For more information about configuring PowerExchange CDC for Db2 for LUW and the PowerExchange Logger, see the PowerExchange CDC Guide for Linux, UNIX, and Windows.
Db2 for LUW CDC Connector works with the Informatica Cloud Secure Agent. When you install and start the Secure Agent, it downloads the Db2 for LUW CDC Connector components and PowerExchangeClient packages. When you define a runtime environment, you configure a Secure Agent group.
Note: Db2 for LUW CDC Connector does not work with the Hosted Agent.
