To enable support for Adabas cipher codes, perform the following actions:

PowerExchange calls the user exit program each time the PowerExchange Listener starts or shuts down. At Listener startup, the exit program provides information for accessing one or more Adabas databases that are protected by an Adabas cipher code. At Listener shutdown, the exit program cleans up resources that the exit program allocated or used.

PowerExchange stores the cipher code in encrypted format in memory while the PowerExchange Listener is running so that the cipher code is not visible in memory dumps.

The user exit program returns one of the following return codes:

Informatica recommends that you set the first parameter of the SECURITY statement in the DBMOVER configuration file to 2. This setting ensures that the user ID assigned to the PowerExchange Listener can run with a RACF authorization and authentication that are different from those of the individual data access tasks. By defining security setup in this way, PowerExchange switches the Listener subtask to the RACF user ID that is provided on the PowerExchange Listener request, regardless of whether the request is from the PowerExchange Navigator, a PowerCenter workflow, or an Informatica client tool. All data access requests that are directed to PowerExchange are performed with the RACF authorization of the user account that is making the request.

Sample user exit programs, such as LSUUXADC, are provided in the SRCLIB library on z/OS.
