Troubled to get scheduler job to run?

Question

Hi all friends:
I'm having trouble getting any scheduler jobs (here, troubled job name is CUSTMASTER_CHANGES_01) to actually run.
when
sql>select job_name,state,enabled,retry_count,failure_count,run_count,restartable,start_date,repeat_interval,job_class
from all_scheduler_jobs;
JOB_NAME STATE ENABL RETRY_COUNT FAILURE_COUNT RUN_COUNT RESTA START_DATE REPEAT_INTERVAL JOB_CLASS
CUSTMASTER_CHANGES_01 SCHEDULED TRUE 0 0 0 FALSE 14-JAN-08 09.46.14.6 FREQ=SECONDLY;I SCANNER_JO
72965 AM AMERICA/NEW NTERVAL=5 B_CLASS
_YORK
for job 'CUSTMASTER_CHANGES_01'
we can see RUN_COUNT 0 and restartable false.
I upped slave processes to 5. dbms_scheduler.run_job('CUSTMASTER_CHANGES_01') works, but it's still not executing on the schedule
when run as sysdba
SQL> exec dbms_scheduler.run_job('CUSTMASTER_CHANGES_01');
ERROR at line 1:
ORA-27475: "SYS.CUSTMASTER_CHANGES_01" must be a job
ORA-06512: at "SYS.DBMS_ISCHED", line 150
ORA-06512: at "SYS.DBMS_SCHEDULER", line 441
ORA-06512: at line 1
to resolve that,
we found
When you create your job by using dbsm_scheduler, it has a parameter called ‘auto_drop’, is by default, =’true’, like, auto_drop => TRUE
see below;
dbms_scheduler.create_job(
job_name IN VARCHAR2,
job_type IN VARCHAR2,
job_action IN VARCHAR2,
number_of_arguments IN PLS_INTEGER DEFAULT 0,
start_date IN TIMESTAMP WITH TIME ZONE DEFAULT NULL,
repeat_interval IN VARCHAR2 DEFAULT NULL,
end_date IN TIMESTAMP WITH TIME ZONE DEFAULT NULL,
job_class IN VARCHAR2 DEFAULT 'DEFAULT_JOB_CLASS',
enabled IN BOOLEAN DEFAULT FALSE,
auto_drop IN BOOLEAN DEFAULT TRUE,
comments IN VARCHAR2 DEFAULT NULL);
The job you manually run once and then it drops itself when you test.
so I am specifiying auto_drop to be false, but it is showing it has true as the attribute.
DBMS_SCHEDULER.CREATE_JOB(
job_name => scanner.scanner_name,
job_type => 'PLSQL_BLOCK',
job_action => 'BEGIN IF EEG_SCAN.GET_RUNNING_JOBS_COUNT('
||''''||UPPER(scanner.scanner_name)||''''
||') < 2 THEN '||scanner.scanner_proc_name||'; END IF; END;',
repeat_interval => 'FREQ=SECONDLY;INTERVAL=5',
job_class => c_job_class_name,
auto_drop => FALSE,
enabled => true
scheduler job is still not working as expected.....?
Can you help me for this??
thanks a lot in advance.

Hi,
There are a few other limits you could check .
Make sure that you have not exceeded the maximum number of sessions or the maximum number of processes or the maximum number of scheduler jobs
select * from dba_scheduler_global_attribute;
and
select name,value from v$parameter where name like '%process%';
select name,value from v$parameter where name like '%session%';
Also check how many jobs are currently running
select count(*) from dba_scheduler_running_jobs;
select count(*) from dba_jobs_running ;
select count(*) from v$session ;
One of these limits may need to be increased.
The run_job succeeds because it runs in the current session by default, if you use use_current_session=>false, does it still work ?
Also auto_drop only drops the job when it has completed e.g. past its end_date or exceeded its max_runs.
Finally note that there is a dedicated forum for dbms_scheduler located here
Scheduler
Hope this helps,
Ravi.
