Step By Step Remove Oracle Table Lock

Posted on by Osama Mustafa in Database
All your query should be done using sys user or system user, after that you need to find Session SID with below query :

SQL> SELECT SESSION_ID
  2  FROM DBA_DML_LOCKS
  3  WHERE NAME = ‘EMP_INFORMATION’;

Where EMP_INFORMATION is Table_name

Output :

SID
___
424

Next step it’s talking about How to find Serial# :

SELECT SID,SERIAL#
FROM V$SESSION
WHERE SID IN (SELECT SESSION_ID
FROM DBA_DML_LOCKS
WHERE NAME = ‘EMP_INFORMATION’)

Output :

SID                SERIAL#
—-                 ——-
424                 1103

Use Alter system To kill this session :
ALTER SYSTEM KILL SESSION ‘SID,SERIALl#’;

Thank you
