Calling the shell scripts written in Apps Server via DBMS_Schedueler

Question

Hi All,
I am new to DBMS Shceduler.
I had written shell scripts in Application Server(Not in Database Server).
Is any one can advice me whether these shell scripts can be called via DBMS SCHEDULER?
Thanks in Advance

Answer 1

Yes.
Generally a Scheduler will have 3 parts, a Schedule, a Program and a Job. The parameter "program_type" in "Program" that can have these values 'PLSQL_BLOCK', 'STORED_PROCEDURE','EXECUTABLE'. The "EXECUTABLE" setting allows you to call a script as you request.
Schedule Example
begin
  dbms_scheduler.create_schedule 
  (schedule_name => 'DAILY_AT_4PM', 
   start_date=> trunc(sysdate)+18/24, 
   repeat_interval=> 'freq=daily;byhour=16;byminute=0;bysecond=0',
   comments=>' Run at 4pm every day'); 
end;You can setup and reuse something like the above for a job you want to run daily at 4PM
You can check schedules by running some SQL like this :
select schedule_name, schedule_type, start_date, repeat_interval from dba_scheduler_schedules where owner = 'SCOTT';
Program Example
BEGIN
DBMS_SCHEDULER.CREATE_PROGRAM (
   program_name           =>  'MY_SAVED_PROGRAM1',
   program_action         => '/usr/local/bin/date',
   program_type           => 'EXECUTABLE',
   comments               => 'My comments here');
END;
/You can check Programs by running some SQL like this :
SELECT owner, program_name, enabled FROM dba_scheduler_programs where owner = 'SCOTT';
Job Example
begin
  dbms_scheduler.create_job
  (job_name => 'JOB_EXAMPLE',
  program_name=> 'MY_SAVED_PROGRAM1',
  schedule_name=>'DAILY_AT_4PM',
  enabled=>true,
  auto_drop=>false,
  comments=>'Job to run date');
end;You can check Jobs by running some SQL like this :
SELECT owner, job_name, enabled FROM dba_scheduler_jobs where owner = 'SCOTT';
The forum also has its own section for this which you can find here :
Scheduler
