When debugging a Mainframe Subsystem application, you need to specify an enterprise server instance that the application will
run on:
- Select your project in COBOL or PL/I Explorer.
- Click
Run > Debug As, and select the type of application you are debugging - either CICS, IMS or JCL.
If your project is not associated with an enterprise server, Eclipse displays an
Select Enterprise Server dialog box.
- Click one of the available enterprise server instances, or click
Create temporary server, and click
OK.
