I have a Stored procedure which needs to be run every minute, for that I have a job in Oracle 10g. I have created a job

BEGIN
  -- Job defined entirely by the CREATE JOB procedure.
  DBMS_SCHEDULER.create_job (
    job_name        => 'Update_Status',
    job_type        => 'PLSQL_BLOCK',
    job_action      => 'BEGIN ;updateStatus; END;',
    start_date      => SYSTIMESTAMP,
    repeat_interval => 'freq=minutely; bysecond=0;',
    end_date        => NULL,
    enabled         => TRUE,
  auto_drop          =>   FALSE,
    comments        => 'Job defined entirely by the CREATE JOB procedure.');
END;

This above job needs to run for every one minute. But the status is not being updated? I do not know whether the job is stared or not how to get the status of the job, How to make it run?
