I am on database 10.2.0.5, windows x64.
A developer calls me and tells me there are locks on 3 tables, and the locks are not released. So I run this to see which objects are locked by which session
select vlo.object_id, vlo.session_id, vlo.oracle_username, vlo.process
, DECODE(vlo.LOCKED_MODE, 0,'NONE', 1,'NULL', 2,'ROW SHARE', 3,'ROW EXCLUSIVE', 4,'SHARE', 5,'SHARE ROW EXCLUSIVE', 6,'EXCLUSIVE', NULL) LOCK_MODE
, do.owner, do.object_name, do.object_type
[code]...
When I run the query later, I sometimes get another session, but the lock stays. It seems here, that I am catching the same SID on new sessions, but it is probably a different serial # than the original session locking the table rows.
I get nothing from
select * from dba_waiters;
select * from dba_blockers;
Now why are those 3 tables row locked on some rows and I can't find the session responsible? The developer tells me his application crashed and the rows are locked since. So far ( keep in mind I am not a locking expert) the only way I found to release the locks is a DB bounce, its a test DB so no biggy.

/
insert into block_session select rownum,rownum*10 from dual connect by level<=10
/
COMMIT
/
GRANT ALL ON block_session to HR
/
update scott.block_session
SET a=10

Last week we have realized that a user who connects through SQL Developer(as nothing wrong found in application server logs) has made a serious change in the database which created a real mess. The user has done some mischief in some calculations by making some inserts and updates in some important tables in our production database.
How can I find which user or from which IP the change is made.

We have the database user called c88888 and is locked yesterday. I came to this with the following query.
select * from dba_users where username like 'C88888';
Due to invalid password the user was locked. Can we track who hit the database with the wrong password?

I am a developer and not a DBA and I need to find th correct query to find the exact rowid of the record locked on a table. This is for a RAC database and locked record can be from the web form in oracle application server. When I try to get the correct row id, I get the following error:
ORA-01410 - Invalid row id For the criteria, the output is Dbms_Rowid.rowid_create(1, -1, 36, 7845, 0), why I get a -1 for the ROW_WAIT_OBJ#?
Additional Information: The lock type is DML and the lock mode is: Row Exclusive, the table is locked and the program is web oracle forms executing.
I am executing the query in Oracle Database 11g Enterprise Edition Release 11.1.0.7.0
How to accomplish getting the correct rowid? Below is the selection criteria I have:
select vs.inst_id,
vs.audsid audsid,
locks.sid sid,

I am working on oracle 11g and AIX.We were facing some blocking issues.For more investigation on the blocking sesssion we checked active session history of the database.Like session 'A' was blocked by session 'B' ...Now if we check infromation about sessions 'A' it is showing that this session was blocked by session 'B'.
But when we checked for session 'B' informaiton ,it is not showing any thing...from where we can get infromation about session B and in what all scenarios active session history does not show information about blocking session....

I can get "CPU used by this session' value from v$sesstat. That is the value in centiseconds used by each session. How to convert the value into a percentage of total CPU resource ?
Or there are some other ways to gain the value. i.e. Percentage of Total CPU usage for each Oracle session.

As stated in "Determining which Oracle database session is being used by a specific Siebel user session [ID 863771.1]":
On the Oracle database side, you can query the V$SESSION table (make sure you are logged in as the tableowner) using the following WHERE clause format:
WHERE PROCESS='XXXX:YYYY'
XXXX = Server PID
YYYY = Thread ID
So querying v$session, sessions opened by windows clients have in the PROCESS column values like "12345:876", where 12345=process id and 876=thread id.
Our application servers are installed in AIX, which is also multithreaded, but in the PROCESS column only process id is stored. Is there any way to find thread id?
