Integration with the PowerExchange environment

You must have a functional on-premises PowerExchange environment that can connect to a Db2 for z/OS database.
You must have a license that allows your organization to use the Db2 for z/OS Connector and PowerExchangeClient packages. On each system from which you plan to use Db2 for z/OS Connector, install the Secure Agent. After you start the Secure Agent the first time, the Db2 for z/OS Connector and PowerExchangeClient package are installed locally. You then can use Cloud Data Integration, Administrator, and Monitor interfaces to configure Db2 for z/OS connections, mappings, and mapping tasks and to run and monitor mapping tasks.
The following image shows the general architecture of the Db2 for z/OS Connector components in relation to Cloud Data Integration and the remote Db2 for z/OS source system:
This configuration spans the following on-premises systems:
Based on this configuration, the following processing occurs:
  1. 1PowerExchange reads from and writes to Db2 tables where the PowerExchange Listener for z/OS resides.
  2. 2When you design a mapping in Data Integration, you associate the source or target transformation with a Db2 for z/OS connection. You can define the connection in either Data Integration or Administrator. The PWX Bulk Metadata Adapter then uses the connection to connect to the PowerExchange Listener on z/OS and read from and write to Db2 tables.
    3. In the mapping, you must also define a Target transformation and connection and map the source fields to target fields.
  3. 3The Secure Agent in conjunction with Data Integration sends the Db2 metadata to the Informatica Intelligent Cloud Services repository in the cloud.
  4. 4When you run the mapping task that is associated with the mapping, all of the metadata, connection properties, mapping information, advanced source properties, runtime properties, and advanced session properties are pushed down to the on-premises Secure Agent in the form of a session .xml file.
  5. 5The PWX Bulk Reader and Writer on the Secure Agent machine communicates with the PowerExchange Listener on the z/OS machine to move bulk data through the PowerExchange Listener.
  6. 6Data Integration transmits the data to the mapped target.
