If you want to debug a program that is already running, you can attach to it using the Attach Process dialog box.

You might attach a running process if:

• You want to debug a running server and you do not want to stop or kill it.
• You want to debug a running GUI program, and you don't want to restart it.
• Your program is looping indefinitely, and you want to debug it without killing it.

To attach to a running process:

1. In the Sun WorkShop main window or the Debugging Window, choose Debug Attach Process.

The Attach Process Dialog Box displays a scrolling list of all active processes on your machine that have your User ID.

2. Select the process you want to attach to.

3. Type the path name of the program in the Program Pathname text box.

You can attach to a process without entering the program name, but you will not be able to run the program at a later time.

4. Click Attach.

The process stops executing and is under debugging control. You can now set breakpoints, step through the program, evaluate expressions, or run any other debugging commands.
