Removing Locks in Oracle 10

This will exactly serve your purpose:

SELECT SESSION_ID FROM DBA_DML_LOCKS WHERE NAME = <TABLE_NAME>;

Use the SESSION_ID to find the corresponding SERIAL# with this statement:

SELECT SID, SERIAL# FROM V$SESSION WHERE SID IN (
    SELECT SESSION_ID FROM DBA_DML_LOCKS WHERE NAME = <TABLE_NAME>
);

Locate the offending tuples SID, SERIAL# and release it like this:

ALTER SYSTEM KILL SESSION 'SID, SERIAL#';

Managed to resolve this issue.

I looked in DBA_BLOCKERS table and got the session ID. Then killed the session and the lock was removed.
