I want to create a procedure that kills the sessions of the user TEST.
I have coded the below, but that dont work.
CREATE OR REPLACE PACKAGE BODY SYSTEM.test AS procedure killsessions IS
v_sessions_sql varchar2(40);
--v_sessions_sql2 varchar2(40);
[Code].....
i was gone through the below link

so when i changed my idle_time value in profile and the when the user exceeds the idle_time value the user still i can see in-active state in v$session.
and when i was tried to execute any query on inactive session that time i got an ORA- error and then session was not visible from v$session.
in my environment inactive session was not getting used afterwards so is there any way to kill that sessions automatically once reached idle_timeout value.
lets say i have 50 max sessions, out of which 10 are inactive state and 40 in active state .what if i created one more sessions will that give me ORA- error stating max sessions reached or it will kill the one session which are in-active state.
I am calling one procedure through job and after submitting the job i am using commit. problem is when job close the session it commit the code which is inside procedure and as per my understanding in another session also, which i want to avoid .
my procedure is
Create My_proc is
Begin
Insert into my_table values(1,2,3);
End;
And my job proc is
Create my_job_proc is
Begin
dbms_job.submit(jobno,'my_proc;',sysdate,null,null,false);
commit;
End;
now i am calling my job proc is
Declare
Begin
my_job_proc;
End;
Now problem is once it finish, it will insert the data into my_table which i don't want until I call Commit.I already try 'Set autocommit off'
I killed the session using the command like :
alter system kill session '454,48158';
but again it is showing the session in v$session view. How can i kill the session.
My disk is completely full so i decided to drop temporary tablespace and create a new one but unfortunately the query to drop temp tablespace hang in between to whic I come to know that there were some sessions which were using it for sort purpose.
check out the queries below with results:
SQL> SELECT b.tablespace,b.segfile#,b.segblk#,b.blocks,a.sid,a.serial#,
2 a.username,a.osuser, a.status
3 FROM v$session a,v$sort_usage b
4 WHERE a.saddr = b.session_addr;

Was able to killed three of the four sessions but not the last one.
i used below code to call Report from Form
Function to call procedure to run report:
DECLARE

its showing report output in a new window, but problem is that if i copy the url, then close current report browser window, start new IE session and paste the copied url it showing the same report... but i don't want to allow this and want to Kill the current job id ( while it displaying the same report ), how i can do this?
Iam unable to kill one database session, Today i killed one session

418 12499 KILLED
we all know we can kill by using ORAKIL but still we unable to kill
SQL> select spid from v$process a, v$session b where a.addr = b.paddr and b.sid = '418';
SPID

i killed using orakill

Kill of thread id 5644 in instance oraci successfully signaled. but still process exits in os level also i notice below error in alert log
orakill: ssthreadkill(tid=5644) unable to get the thread list mutex: err=0
Which is the best way to kill a session?
alter system kill session sid,serail#
or
kill -9 spid
or
orakill sid,thread
I am using unix,windows operating system.
How to kill of a killed session?
I had killed inactive session using alter system kill session 'sid,serial#';
after that that sessions marked as killed and still get in v$session.
Then i try to get spid so that i can killed then from os command kill -9 spid
but when i try to get that join with v$process, no row select.
select * from v$session where username ='CAS' and status ='KILLED'
return 205 records.
select p.*,s.username,s.program,s.machine,s.status from v$process p,v$session s
where p.addr=s.paddr and s.status='KILLED'
return no record.
we have third party application which uses oracle database (version 10.2.0.5) on WINDOWS. Our no of process used keeps increasing by 15-20 everyday.
However number of sessions remain constant 32-35 . So in couple of days we reach our limit of max processes and DB needs to be restarted to release processes.
How to identify unwanted process ?? is it safe to kill process(windows threads) which have V$PROCESS.ADDR not equal to V$SESSION.PADDR using orakill or some other third party utility or should I use another way ??
No of sessions remains constant and currently we don't have control over application.
My code executes a Select For Update before updating a table. In some cases the network is disconnected and it causes the lock to hang. Then, I must kill the session in order to realese this lock.
I want to do it automatically. I would like to create a job that kills session that has a lock due to Select For Update that is not alive.
We started a full db export using exp, and we need to kill it. Is it "safe" to do so? Killing it won't affect the database in any way, right?
$ORACLE_HOME/bin/exp system/xxxxxx BUFFER=140000 FULL=Y FILE=/export/<sid>.exp VOLSIZE=2000M GRANT
S=Y INDEXES=Y COMPRESS=Y
how could we kill oracle database session from javascript/java application.
View 2 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.
I have set my processes and session value in my database as 1000 and 1248 respectively. I am using 11.2.0.1 but when I restart my DB it showing me sessions=1524...its too high value then what I set.I don't know why it showing higher value than the value I set...
ALTER SYSTEM SET processes=1000 SCOPE=SPFILE;
ALTER SYSTEM SET sessions=1248 SCOPE=SPFILE;
Starting up:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options.
Using parameter settings in server-side spfile /u02/app/oracle/product/11.2.0/db_1/dbs/spfileeng11g02.ora
System parameters with non-default values:
processes = 1000
sessions = 1524
And one more thing is there any recommended formula for calculate sessions in 11g? [ I found one formual from google:
SESSIONS derived: (1.1 * PROCESSES) + 5
One of our DB server is high on CPU utilization, as per the AWR we found couple of queries are running many times and taking huge CPU, hence we need to know from which user these queries are runnings.find the session information as per the sql id?

Database is not releas the sessions.
our db shows more than 200 INACTIVE Sessions ; and the DBA plans to reboot the db to get rid of these sessions . Can we not KILL these sessions and avoid the reboot ?
View 4 Replies View RelatedI'm using Toad 11.6, I can see about 156 sessions for the database in the session browser but when I do a select from v$session, only 40 sessions are showing up. I was able to look at all the sessions until yesterday. I tried several views like v$session, v$open_cursor etc, but only 60 sessions show up. I'm connected to the database using same user login yesterday and this morning.. May be this user had some privileges revoked last night??If so is it possible to limit sessions in these views (v$session etc) but it's strange that I can see them in the session browser in Toad. 'm very confident that there are 156 sessions in the database but it's just that I'm not able to see them in the v$session etc views. I need to troubleshoot a session but it is not showing up in any views.

I want to change the the number of processes to 150 (default is 100) I did this by issuing the below command.
alter system set processes=150 scope=spfile;But why that modified value is not being reflected?
select name, value from v$parameter where name in ('sessions','processes','transactions');
NAME VALUE
-------------------- -----
processes 100
sessions 172
transactions 189
Is there any way to tell what processes/sessions were connected to a DB after I get an ORA 20error. As you can see from the query results below, I did hit the max value of processes but I would like to know when it happen and who was connected.
I realize I can up the value, but before I do that I want to see what caused this to happen.
SQL> select * from v$resource_limit where resource_name in ('sessions', 'processes');
RESOURCE_NAME CURRENT_UTILIZATION MAX_UTILIZATION INITIAL_AL
LIMIT_VALU
----------
processes 221 1000 1000
1000
sessions 223 1020 1105

SESSIONS_PER_USER
Each instance maintains its own SESSIONS_PER_USER count. If SESSIONS_PER_USER is set to 1 for a user, the user can log on to the database more than once as long as each connection is from a different instance.

Of course the following is not working even when resource_limit is TRUE
ALTER PROFILE DEFAULT LIMIT SESSIONS_PER_USER 2;
How can I restrict a user to have limited sessions say 2 sessions across 4 node cluster? Presently I am checking the sessions logged in using sql+ and no connection pooling of front end etc. is involved.
I have an assignment, i am suppose to disconnect all the users that are blocking sessions for over three hours. Below is my code which is not working
Create or replace procedure b_user IS
Declare
ssid number;
serial number;

how to avoid oracle deadlock with two sessions. Here is my example, We use Select query with For Update in order to get the unique number from a table. When one user has accessed this query, while the other user tries, System gives a Performace slow and when checked it is due to locking of this select query with For update.
We don't want to use For update WAIT or FOR UPDATE NOWAIT since these will result in missing of number.
why are there in the Administration --> --> Session 2 entries for 1 database connection (here with benthic golden).But if I login in a browser, there is only 1 entry for this database connection

I create table in session1:
create table marco_tmp_270511
as
select 5 as t from dual
Then I log in session2 and perform query to
select * from marco_tmp_270511 and receive 5 in column t.
Then I return to session1 and perform:
delete marco_tmp_270511;
insert into marco_tmp_270511
select 99 as t from dual ;
select * from marco_tmp_270511;
Then I go again to session2 and perform query to
select * from marco_tmp_270511
and still receive 5 in column t. How do I synchronize data between sessions?
I need to identify, whether my current session is one of slave sessions scheduled as Oracle scheduler job via DBMS_PARALLEL_EXECUTE or not. I already succeeded using join of dba_scheduler_running_jobs, user_parallel_execute_chunks and v$session, but I feel that this is not optimal approach.
