The handler command modifies event handlers (enable, disable, etc.). It has identical syntax and identical functionality in native mode and in Java mode.
A handler is created for each event that needs to be managed in a debugging session. The commands trace, stop, and whencreate handlers. Each of these commands returns a number known as the handler ID (handler_id). The handler, status, anddelete commands manipulate or provide information about handlers in a generic fashion.
Enable given handlers, specify handler_id as all for all handlers.
Disable given handlers, specify handler_id as all for all handlers. Use $firedhandlers instead of handler_id to disable the handlers that caused the most recent stoppage.
Print value of trip counter for given handler.
Set new count limit for given event.
Reset trip counter for given handler.
handler_id is the identifier of a handler.
