一、Oracle DDL锁的解锁

Oracle分两种锁，一种是DDL锁，一种是DML锁。

1.1、查表的DDL锁

查DDL锁的数据字典，SQL如下：

select * from dba_ddl_locksWHERE owner = 'TZQ'AND NAME LIKE '%TZQ_LOG_T%'

1.2、根据session_id找SID,SERIAL#

根据session_id找SID,SERIAL#，SQL如下：

select s.INST_ID,s.SID,s.SERIAL# from gv$session s where 1=1-- AND s.INST_ID =1 and s.SID IN (6335);

1.3、杀会话kill session

打开命令行窗口，执行下面命令：

AUTO_SERVER_PKG
execute sys.auto_server_pkg.kill_session(6335,15519);

二、Oracle DML锁的解锁

Oracle分两种锁，一种是DDL锁，一种是DML锁。

2.1、查表的DML锁

查DML锁的数据字典，SQL如下：

select /*DISTINCT '''' || s.sid || ',' || s.serial# || ',@' ||s.INST_ID || '''' AS si_id*/*from gv$locked_object l, dba_objects o, gv$session swhere l.object_id = o.object_idand l.session_id = s.sidand l.inst_id = s.inst_idand o.owner = upper('TZQ')and o.object_name = upper('TZQ_LOG_T');

2.2、根据session_id找SID,SERIAL#

根据session_id找SID,SERIAL#，SQL如下：

select s.INST_ID,s.SID,s.SERIAL# from gv$session s where 1=1-- AND s.INST_ID =1 and s.SID IN (6335);

2.3、杀会话kill session

打开命令行窗口，执行下面命令：

AUTO_SERVER_PKG
execute sys.auto_server_pkg.kill_session(6335,15519);

三、附录

3.1、根据sid查sql_text

SELECT s.sid,s.serial#,s.sql_id,s.sql_hash_value,s.username,a.sql_textFROM gv$session sLEFT JOIN v$sqlarea aON s.sql_id = a.sql_idWHERE s.sql_id IS NOT NULL;
