For the Host Debug Tool, you need to verify that the JCL you generated
in Developer for System z® uses
the required test runtime option. When this option is set correctly,
the Host Debug Tool uses a single port to communicate with your workstation.
The default value for this port number is 8001. To verify that the
correct test runtime option is set, do the following steps:
- Generate the JCL for your program
- Verify that the test runtime option is set to TCPIP
