关于DBMS_SCHEDULER job日志级别LOGGING_LEVEL

--job日志级别由两个因素决定,一个是job自己日志级别,别一个是使用的job cloass的日志级别,取两者中的最高值。--job创建时日志级别默认是DBMS_SCHEDULER.LOGGING_RUNS,--创建的job时,如果不指定job class,默认为DEFAULT_JOB_CLASS,而DEFAULT_JOB_CLASS默认logging level是DBMS_SCHEDULER.LOGGING_RUNS,--所以创建的job的logging level至少是LOGGING_RUNS。--如果不产生日志,必须禁止job自己日志级别,同时不能使用默认的默认为DEFAULT_JOB_CLASS.-- 重新建立无日志job classbegin  DBMS_SCHEDULER.create_job_class (    job_class_name          => 'no_logging_class',    resource_consumer_group => 'default_consumer_group',    logging_level           => DBMS_SCHEDULER.LOGGING_OFF);end;  -- Create job links to previous job class.
