1、解鎖用戶

以dba身份登錄?? sqlplus / as sysdba

?alter user scott account unlock;

2、解鎖表

alter?? system?? kill?? session

<!----1.查出鎖定object的session的信息以及被鎖定的object名------------------------------------>

SELECT l.session_id sid, s.serial#, l.locked_mode,l.oracle_username, ?l.os_user_name,s.machine, s.terminal, o.object_name, s.logon_time ?

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# ;

<!---------------------2.查出鎖定表的session的 sid, serial#,os_user_name, machine name, terminal和

執行的語句 --比上面那段多出sql_text和action ----------------------------------------------------------->

SELECT l.session_id sid, s.serial#, l.locked_mode, l.oracle_username, s.user#, ?l.os_user_name,s.machine, s.terminal,a.sql_text, a.action

?FROM v$sqlarea a,v$session s, v$locked_object l ?

WHERE l.session_id = s.sid

?AND s.prev_sql_addr = a.address ?

ORDER BY sid, s.serial#; ?

<!-------------------------3.查出鎖定表的sid, serial#,os_user_name, machine_name, terminal，鎖的type,mode ------------------------------------------------------------>

SELECT s.sid, s.serial#, s.username, s.schemaname, s.osuser, s.process, s.machine, ?s.terminal, s.logon_time, l.type

?FROM v$session s, v$lock l

?WHERE s.sid = l.sid ?

AND s.username IS NOT NULL ?

ORDER BY sid; ? ?

?<!--------殺鎖命令---------->??

?? alter system kill session 'sid,serial#'; ? ?

? alter system kill session '3,21395';

?--------------------------- ?

alter system kill session 'sid,serial#' ?SELECT /*+ rule */ s.username, ?decode(l.type,'TM','TABLE LOCK', ?'TX','ROW LOCK', ?NULL) LOCK_LEVEL, ?o.owner,o.object_name,o.object_type, ?s.sid,s.serial#,s.terminal,s.machine,s.program,s.osuser ?

FROM v$session s,v$lock l,dba_objects o

?WHERE l.sid = s.sid

?AND l.id1 = o.object_id(+) ?AND s.username is NOT NULL
