ORACLE 查看 执行时间长的SQL

1. ORACLE  查看 执行时间长的SQL

SELECT S.SQL_TEXT,

       S.SQL_FULLTEXT,
       S.SQL_ID,
       ROUND(ELAPSED_TIME / 1000000 / (CASE
               WHEN (EXECUTIONS = 0 OR NVL(EXECUTIONS, 1) = 1) THEN
                1
               ELSE
                EXECUTIONS
             END),
             2) "执行时间'S'",
       S.EXECUTIONS "执行次数",
       S.OPTIMIZER_COST "COST",
       S.SORTS,
       S.MODULE, --连接模式（JDBC THIN CLIENT：程序）
       -- S.LOCKED_TOTAL,
       --S.PHYSICAL_READ_BYTES "物理读",
       -- S.PHYSICAL_READ_REQUESTS "物理读请求",
       --S.PHYSICAL_WRITE_REQUESTS "物理写",
       -- S.PHYSICAL_WRITE_BYTES "物理写请求",
       S.ROWS_PROCESSED      "返回行数",
       S.DISK_READS          "磁盘读",
       S.DIRECT_WRITES       "直接路径写",
       S.PARSING_SCHEMA_NAME,
       S.LAST_ACTIVE_TIME
  FROM GV$SQLAREA S
 WHERE ROUND(ELAPSED_TIME / 1000000 / (CASE
               WHEN (EXECUTIONS = 0 OR NVL(EXECUTIONS, 1) = 1) THEN
                1
               ELSE
                EXECUTIONS
             END),
             2) > 5 --100 0000微秒=1S
   AND S.PARSING_SCHEMA_NAME = USER
   AND TO_CHAR(S.LAST_LOAD_TIME, 'YYYY-MM-DD') =
       TO_CHAR(SYSDATE, 'YYYY-MM-DD')
   AND S.COMMAND_TYPE IN (2, 3, 5, 6, 189)

 ORDER BY "执行时间'S'" DESC;

2. ORACLE  查看 锁表的SQL ,TOAD 的session Browser 也可以

SELECT a_s.owner,
  a_s.object_name,
  a_s.object_type,
  VN.SID,
  VN.SERIAL#,
  VS.SPID"OS_PID",
  VN.PROCESS"CLIENT_PID",
  VN.USERNAME,
  VN.OSUSER,
  VN.MACHINE"HOSTNAME" ,
  VN.TERMINAL,
  VN.PROGRAM,
  TO_CHAR(VN.LOGON_TIME,'YYYY-MM-DD HH24:MI:SS')"LOGIN_TIME",
  'alter system kill session '''||vn.sid||','||vn.serial#||''';'"ORACKE_KILL",
  'kill -9 '|| VS.SPID"OS_KILL"
FROM ALL_OBJECTS A_S,
  V$LOCKED_OBJECT V_T,
  V$SESSION VN,
  V$PROCESS VS
WHERE A_S.OBJECT_ID=V_T.OBJECT_ID
AND V_T.SESSION_ID =VN.SID
AND VS.ADDR=VN.PADDR
AND VN.USERNAME NOT IN('SYSMAN','SYS');
