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.
Is their any query to find cpu usage & memory usage of all the queries currently running on DB?
View 5 Replies View RelatedI have an urgent requirement to kill an existing session if a new session starts for the same user. I have been reading lot of blogs and posts on the above topic, but could clearly tell me how to do it.
I thought of putting a process in 101 page when login button is pressed to catch this and kill the old session.
User session has expired. I have to enable user without changing the password of the user.

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....
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?
I have a user in my oracle database, I would like to know details such as, how many times and by using which tools same user has got logged for past one week.
How do I do that. I have sql which shows the current session either he is logged in, if so then which application or not logged in. But I required the information for past one week How do I get those details.
How can I find out a user session/connection details like ( his last connection time, his activity etc)
Here is the issue, a old dba_user_id who physically no longer exists is not removed from the database. At some time, a session is opened under his user_id and some activity runs and closes the session. So, checked scheduled jobs under him and disabled them. But not sure whether the scheduled jobs are creating a session under his user_id or some thing else.
I checked in v$session, but since I am not sure at what time his session opens, so I am not able to get his session details.
I need a query to find out IP Adress for all currently connected users in V$session.

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.
I used to find out locked table and session from database....query with SYS user but i want to hand over the user session kill role to location level IT person so i have created one user in database named as rab and i have given "select any table,alter session and Grant dba to that rab user,but with that user they will drop and delete any table also

We have an application with database Oracle 10g.
I want to add a new validation to restrict concurrent user and/or session from a client. (we have almost 60 client firms using the software to enter daily trasnactions). All users from all clients are connecting to the database using a common functional ID.
What I did was:
1) Add a column 'user_logged_in' in the master table for client and update it as Y when user from that client logged on to the system,
2) Insert the application logon details (we can figure out the client details from this) into a global temp table,
3) Create a logoff trigger to update the 'user_logged_in'flag in client master table by using values from global temp table when session logged off and
4) Restrict the users from same client if the flag is 'Y'
But the problem in this case is logoff trigger will not be executed in case if the session got killed or terminated abnormally.

How I can find the hostname for an oracle session id?
View 4 Replies View RelatedI am using TOAD to monitor user sessions. I have a user who uses nearly 80% of Overall resources in the mornings. He calls me daily and say that his work is done. But even then the TOAD shows that he is using same resources for some time.
My question is can i kill the session once he confirms his work is done OR do i need to wait till the redologs are cleared.
We have a package procedure called from SSRS , which returns a REFCURSOR to the SSRS.Sometimes it throws the error. The user Refresh the SSRS session and again run the query , the error does not happen
Following is the error number
ORA-01001: invalid cursor
We have not used any static cursor , so this is not happening because we have opened a cursor and not closed it.The Cursor used is REF CURSOR and the output parameter is declared as
---------------
p_ref_cursor OUT SYS_REFCURSOR
----------
The Procedure returns the Select query in the REF CURSOR.

,in 11g,is there a way I could limit the number of open application actions by some os user ?We have an application where users are executing the same thing while the last is not yet finished,so we have several same things runninng at the same time executed by the same user.
Can we restrict that somehow through the database or that needs to be done through application?
How do you find the youngest user in a certain table
select a.illness_desc
from uma.pc_illness a, uma.pc_patient b, uma.pc_diagnosis c
where b.patient_no = c.patient_no and c.illness_code = a.illness_code
and b.age = '21';
i currently have this (it also needs to display their illness which i have done) but i can do only if i cheat and see what the youngest user is, so instead of b.age = 21 i need something that will search the database and find that youngest age
we are using SQL+
