Cause

The problem is caused by illegal characters in the name of the subscriber that is associated with the Data Receiver.

Solution

Change the subscriber name in the policy to remove illegal characters.

To check the subscriber name, perform the following steps.
  1. Access the Policy in the Configuration Tool.
  2. Edit the subscriber that is associated with the Data Receiver.
  3. Check the name of the subscriber in the field Name of the Configure subscriber window.
In this example, the subscriber name is datareceiver su z/OS SYSC2 with the illegal character /. Rename the subscriber to something similar to datareceiver_ZOS_SYSC2. The Data Steamer will start properly afterward.
