Launching and debugging your application with IBM Z® Open Debug on Wazi Developer for VS Code

The IDE uses launch.json to control the configuration and invocation of debug adapters for various languages and runtimes. Z Open Debug provides two launch.json configuration types for working with z/OS® Debugger sessions on a remote z/OS host.

You can use a launch type of configuration to active a debug profile, start and debug an application.
Or you can use other methods to launch an application, and then use an attach type of configuration to list debug sessions parked on the z/OS host and connect to any debug session available in the pop-up selector.

The method to launch an application varies according to the type of application, subsystem (CICS®, IMS, Db2®, Batch), and z/OS environment. Check how you prepared your application environment to find the appropriate method to invoke your application or transaction under the control of z/OS Debugger.

For more information about how to debug in VS Code, see the topic about debugging in the VS Code documentation.

Note: Not all debug features in VS Code are supported by Z Open Debug. See the Remote client debug feature comparison table for a list of supported features and Known issues and limitations for Z Open Debug with Wazi Developer for VS Code for limitations.
