Starting dbx and Loading Your Program

To start dbx, type the dbx command at a shell prompt:

$ dbx

To start dbx and load the program to be debugged:

$ dbx program_name

To start dbx and load a program that is a mixture of Java code and C JNI code or C++ JNI code:

$ dbx program_name{.class | .jar}

You can use the dbx command to start dbx and attach it to a running process by specifying the process ID.

$ dbx - process_id

If you don’t know the process ID of the process, include the pgrep command in the dbx command to find and attach to the process. For example:

$ dbx - ”pgrep Freeway”

For more information on the dbx command and start-up options, see dbx Command and the dbx(1) man page, or type dbx -h.

If you are already running dbx, you can load the program to be debugged, or switch from the program you are debugging to another program, with the debug command:

(dbx) debug program_name

To load or switch to a program that includes Java code and C JNI code or C++ JNI code:

(dbx> debug program_name{.class | .jar}

If you are already running dbx, you can also use the debug command to attach dbx to a running process:

(dbx) debug program_name process_id

To attach dbx to a running process that includes Java code and C JNI (Java Native Interface) code or C++ JNI code:

(dbx) debug program_name{.class | .jar} process_id

For more information on the debug command, see debug Command.
