sql;">
SELECT b.sid oracleID,b.username 登录Oracle用户名,b.serial#,spid 操作系统ID,paddr,sql_text 正在执行的sql,b.machine 计算机名
FROM v$process a,v$session b,v$sqlarea c
WHERE a.addr = b.paddr
AND b.sql_hash_value = c.hash_value
sql;">
select a.username,a.sid,b.sql_TEXT,b.sql_FULLTEXT
from v$session a,v$sqlarea b
where a.sql_address = b.address
---执行过的
select b.sql_TEXT,b.FIRST_LOAD_TIME,b.sql_FULLTEXT
from v$sqlarea b
where b.FIRST_LOAD_TIME between '2016-10-1/09:24:47' and
'2016-10-1/09:24:47' order by b.FIRST_LOAD_TIME
（此方法好处可以查看某一时间段执行过的sql，并且 sql_FULLTEXT 包含了完整的 sql 语句）
其他
sql;">
select OSUSER,PROGRAM,USERNAME,SCHEMANAME,B.cpu_Time,STATUS,B.sql_TEXT
from V$SESSION A LEFT JOIN V$sql B ON A.sql_ADDRESS=B.ADDRESS AND A.sql_HASH_VALUE=B.HASH_VALUE order by b.cpu_time desc
select address,sql_text,piece
from v$session,v$sqltext
where address = sql_address
-- and machine = < you machine name >
order by address,piece
查看正在执行sql的发起者的发放程序
sql;">
SELECT OSUSER 电脑登录身份,PROGRAM 发起请求的程序,USERNAME 登录系统的用户名,B.cpu_Time 花费cpu的时间,B.sql_TEXT 执行的sql
FROM V$SESSION A
LEFT JOIN V$sql B ON A.sql_ADDRESS = B.ADDRESS
AND A.sql_HASH_VALUE = B.HASH_VALUE
ORDER BY b.cpu_time DESC
查出oracle当前的被锁对象
sql;">
SELECT l.session_id sid,s.serial#,l.locked_mode 锁模式,l.oracle_username 登录用户,l.os_user_name 登录机器用户名,s.machine 机器名,s.terminal 终端用户名,o.object_name 被锁对象名,s.logon_time 登录数据库时间
FROM v$locked_object l,all_objects o,v$session s
WHERE l.object_id = o.object_id
AND l.session_id = s.sid
ORDER BY sid,s.serial#;
kill掉当前的锁对象可以为
sql;">
alter system kill session 'sid， s.serial#‘;
查找前十条性能差的sql.
sql;">
SELECT * FROM (select PARSING_USER_ID,EXECUTIONS,SORTS,COMMAND_TYPE,DISK_READS,sql_text FROM v$sqlarea
order BY disk_reads DESC )where ROWNUM<10 ;
查看占io较大的正在运行的session
6 AND st.
wait_time=0 AND st.event NOT LIKE '%sql%' ORDER BY physical_reads DESC
