登陸數據庫，查看等待事件

SELECT * FROM V$SESSION_WAIT WHERE WAIT_CLASS <> 'Idle' ORDER BY SECONDS_IN_WAIT DESC;

查看數據庫正在執行的SQL，發現一直在執行的是DBMS_SCHEDULER模塊，job名是OSMSR_OPERATION_DURATION

select s.SID,s.SERIAL#,MACHINE,TERMINAL, OSUSER, SCHEMANAME, PROGRAM,MODULE,ACTION,CLIENT_INFO,

decode(s.COMMAND,3,'SELECT',s.COMMAND) COMMAND,STATUS,SQL_ID,SQL_ADDRESS,SQL_EXEC_START,

DECODE(STATUS,'ACTIVE',LAST_CALL_ET,NULL) "SQL執行時間",EVENT,STATE,SECONDS_IN_WAIT,SERVICE_NAME

from V$SESSION s where s.USERNAME is not null AND WAIT_CLASS <> 'Idle';

查看job

select job_name,state from dba_scheduler_jobs where state= 'RUNNING';

停止job

SQL> BEGIN

DBMS_SCHEDULER.STOP_JOB('OSMSR_OPERATION_DURATION');

END;? 2??? 3

4? /

PL/SQL procedure successfully completed.

SQL> select job_name,state from dba_scheduler_jobs where state= 'RUNNING';
