You must have a functional on-premises PowerExchange environment that can retrieve records from IDMS data sources on a z/OS system. The IDMS Connector retrieves records from the data map metadata.
You must have a license that allows your organization to use the IDMS Connector and PowerExchangeClient packages on a z/OS system. On each system from which you plan to use IDMS Connector, install the Secure Agent. After you start the Secure Agent the first time, the IDMS Connector and PowerExchangeClient package are installed locally. You then can use Cloud Data Integration, Administrator, and Monitor interfaces to configure IDMS connections, mappings, and mapping tasks and to run and monitor mapping tasks.
The following image shows the general architecture of the IDMS Connector components in relation to Cloud Data Integration and the remote IDMS source system:
This configuration spans the following on-premises systems:
•The Windows system where the PowerExchange Navigator client runs.
•The z/OS system where the IDMS data sources and PowerExchange Listener run.
•The system where the IDMS Connector components and Secure Agent run.
Based on this configuration, the following processing occurs:
1PowerExchange retrieves records from IDMS data sources and sends the data to the PowerExchange Listener for z/OS.
You defined a data map for each IDMS source in the PowerExchange Navigator.
2When you design a mapping in Data Integration, you associate the Source transformation with an IDMS 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 retrieve data map metadata files for the IDMS source from the PowerExchange Listener.
In the mapping, you must also define a Target transformation and connection and map the source fields to target fields.
3The Secure Agent in conjunction with Data Integration sends the data map metadata to the Informatica Intelligent Cloud Services repository in the cloud.
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.
5The PWX Bulk Reader on the Secure Agent machine communicates with the PowerExchange Listener on the z/OS machine to retrieve the records from the PowerExchange Listener.
6Data Integration transmits the records to the mapped target.
Alternative configurations of PowerExchange with the IDMS Connector components and Cloud Data Integration are possible. For example, the PowerExchange Navigator can run on any supported Windows system, including a Windows system where the IDMS Connector and Secure Agent run.
