Job not getting triggered for Multiple Scheduler Events

Question

hi,
I would like a job to be triggered for multiple scheduler events, subscribing to a single event works fine. But, when I set multiple event condition, nothing works.
My objective is to run a job, whenever job starts or restarts or exceeds max run duration.
Note : Is it possible to trigger a job, when a job RESTARTS by subscribing to JOB_START ????????
procedure sniffer_proc(p_message in sys.scheduler$_event_info)
is
--Code
end sniffer_proc
dbms_scheduler.create_program(program_name => 'PROG',
program_action => 'sniffer_proc',
program_type => 'stored_procedure',
number_of_arguments => 1,
enabled => false);
-- Define the meta data on scheduler event to be passed.
dbms_scheduler.define_metadata_argument('PROG',
'event_message',1);
dbms_scheduler.enable('PROG');
dbms_scheduler.create_job
('JOB',
program_name => 'PROG',
* event_condition => 'tab.user_data.event_type = ''JOB_OVER_MAX_DUR''' ||*
*' or tab.user_data.event_type = ''JOB_START''',*
queue_spec => 'sys.scheduler$_event_queue,auagent',
enabled => true);
I tried this too...
dbms_scheduler.create_job
('JOB',
program_name => 'PROG',
* event_condition => 'tab.user_data.event_type = ''JOB_OVER_MAX_DUR''' ||*
*' and tab.user_data.event_type = ''JOB_START''',*
queue_spec => 'sys.scheduler$_event_queue,auagent',
enabled => true);
Need help
Thanks...

Hi,
Here is complete code which I tested on 10.2.0.4 which shows a second job that runs after a first job starts and also when it has exceeded its max run duration. It doesn't have the condition but just runs on every event raised, but the job only raises the 2 events.
Hope this helps,
Ravi.
-- run a job when another starts and exceeds its max_run_duration
set pagesize 200
-- create a user just for this test
drop user test_user cascade;
grant connect, create job, create session, resource,
  create table to test_user identified by test_user ;
connect test_user/test_user
-- create a table for output
create table job_output (log_date timestamp with time zone,
        output varchar2(4000));
-- add an event queue subscriber for this user's messages
exec dbms_scheduler.add_event_queue_subscriber('myagent')
-- create the first job and have it raise an event whenever it completes
-- (succeeds, fails or stops)
begin
dbms_scheduler.create_job
   ( 'first_job', job_action =>
     'insert into job_output values(systimestamp, ''first job runs'');'||
     'commit; dbms_lock.sleep(70);',
    job_type => 'plsql_block',
    enabled => false, repeat_interval=>'freq=secondly;interval=90' ) ;
dbms_scheduler.set_attribute ( 'first_job' , 'max_runs' , 2);
dbms_scheduler.set_attribute
    ( 'first_job' , 'raise_events' , dbms_scheduler.job_started);
dbms_scheduler.set_attribute ( 'first_job' , 'max_run_duration' ,
    interval '60' second);
end;
-- create a simple second job that runs when the first starts and after
-- it has exceeded its max_run_duration
begin
  dbms_scheduler.create_job('second_job',
                            job_type=>'plsql_block',
                            job_action=>
    'insert into job_output values(systimestamp, ''second job runs'');',
                            event_condition =>
   'tab.user_data.object_name = ''FIRST_JOB''',
                            queue_spec =>'sys.scheduler$_event_queue,myagent',
                            enabled=>true);
end;
-- this allows multiple simultaneous runs of the second job on 11g and up
begin
  $IF DBMS_DB_VERSION.VER_LE_10 $THEN
    null;
  $ELSE
    dbms_scheduler.set_attribute('second_job', 'parallel_instances',true);
  $END
end;
-- enable the first job so it starts running
exec dbms_scheduler.enable('first_job')
-- wait until the first job has run twice
exec dbms_lock.sleep(180)
select * from job_output;
