--查看連接的進(jìn)程
SELECT sid, serial#, username, osuser FROM v$session;
--****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,

l.type

這個(gè)語(yǔ)句將查找到數(shù)據(jù)庫(kù)中所有的DML語(yǔ)句產(chǎn)生的鎖,還可以發(fā)現(xiàn),
任何DML語(yǔ)句其實(shí)產(chǎn)生了兩個(gè)鎖,一個(gè)是表鎖,一個(gè)是行鎖。
