Workflow Agent Listener Service WF_DEFERRED + Business Event not processing

Workflow Agent Listener Service WF_DEFERRED Will Not Start, Mailer May Be Down To implement the solution, please execute the following steps: 1.  Use this query to identify any remaining items in wf_deferred queue: SQL> select corrid, decode(state, 0, '0 = Ready', 1, '1 = Delayed', 2, '2 = Retained', 3, '3 = Exception', to_char(state)) State, count(*) COUNT from wf_deferred group by corrid, state; 2. Items with the APPS corrid will not dequeue from agent listener via service container.  This runs the deferred listener from the command lin e . Make sure that the listener and workflow service components - including the mailer - are down before you run this . This is not intended to be a substitute for the normal operation of this service container from the OAM console. Use this only during this cleanup operation. One will have to run this script manually: begin wf_log_pkg.wf_debug_flag := TRUE; wf_event...
