Inactive Sessions In Database?
Dec 12, 2011In our databace there are around 300 sessions were in inactive state.
Database is not releas the sessions.
In our databace there are around 300 sessions were in inactive state.
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 RelatedShare a query for inactive sessions consuming memory? I have found many inactive sessions with the following query and would like to join this information with memory usage as well.
select username, machine, program, to_char(LOGON_TIME, 'hh24:mi:ss DD-MM-YYYY'), LAST_CALL_ET/60, status from gv$session where status='INACTIVE';
lsnrctl RELOAD [listener_name] Hope the above command wont terminate the current sessions to the database.

CASE 1:
user A logs in to a database1
issues select on table A and then inserts 4 rows
user B logs in to databse1
issues select on table A and then inserts 5 rows
issues rollback
user C logs in to a database1
issues select on table A and then inserts 6 rows
issues commit
How many rows can user C see in the table A when he issues select?
CASE 2:
user A logs in to a database1

NOTE: All the users are currently logged in to the same database and none has logged out.
I have a simple question about database sessions. The value of parameter "sessions" is set to 500 and the users connect to database through an application server(Jboss). There are more than 500 users connect to the database through application.
My question is, how more than 500 users can connect to the database without any issue, if we set the value of "sessions" parameter to 500?
Does version 4.2 create a new db session for each report run on a page?
The reason I ask is we have a page with 4 report regions, each querying a global temporary table that is populated in a 'Before Regions' page process. The first report displays the correct data, but the others return 'No Data Found' and it is because the Global Temporary Table has been cleared out following the first report. This did not happen in 4.1.
I know we should be using Apex Collections, and we will in future, but time is at a premium to get this live

Oracle Database 11g Release 11.2.0.1.0 Standard Edition
I recently applied the Oracle® Database Server Version 11.2.0.1 Patch 16 I have several databases running on this box with the same application.Since then I've had lots of customers complaining about slow systems. The server has plenty of RAM availableI also have several other servers all on the same versions, same patch, running the same application with no issues.
Looking at v$session there are often lots of active sessions that have a sql_address of "00". I've never seen this before and I regularly look at v$session, as you can see for below these have been running for a while. The sessions do drop off but I am at a loss as to what is happening.
select username, last_call_et, sid, serial#, user#, status, sql_address, sql_hash_value
from v$session
where username is not null and status = 'ACTIVE'
order by last_call_et desc, sid

We have quite a number of sessions in database MES (production) coming from another machine.
From v$session, the program is oracle@WID27 (TNS V1-V3). This WID27 (hostname) consists of quite a number of development databases inside. We have to trace which jobs are actually triggering this, as WID27 are not suppose to connect to production databases.
How can we tell whether the sessions came in is from dblink or from the machine itself?
want to know the following
1. when the oracle session changed from active to inactive?
2. what is the time for active session?
3. session is changed to inactive from active. but it is still showing in v$session.
4. in v$session, can i see the ipaddress of client machine ?
i was gone through the below link
[URL]
so when i changed my idle_time value in profile and the when the user exceeds the idle_time value the user still i can see in-active state in v$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 have a form having 5 listitems for making selections. once selecting through listitems i am adding this selection into below datablock by a ok button and saving it into database by a ok button. as i made one selection and press ok buttton it's working fine but after this when i want one more selection through listitems, listitems becomes inactive. it's not working after one selection. my coding on ok button is like this:
begin
select distinct lcode intolcode_ss from vac_view where locality=:vac_view.locality;
select distinct hid intohid_ss from vac_clr_vu where vr_no=:vac_view.vr_no;
:prop_temp.vr_no :=:vac_view.vr_no;
:prop_temp.qtr_type :=:vac_view.qtr_type;
:prop_temp.locality :=:vac_view.locality;
[code]....
may be it's all because of clear_list('vac_view.locality'); but i have to put this as i want to make clear all listitems after making each selections.
when I was analyzing high CPU utilization issue, I saw that the most of the top PID's were INACTIVE in database. But it was utilizing more than 4% CPU. how it is utilizing CPU without doing any work in database?

While when i see the current sql from the v$active_session_history, it keep on changing after every 10-15 minutes. Using below query to find the sql_text for the session from v$active_session_history.
select sql_id, sql_text
from v$sql
where sql_id in (
select sql_id
from v$active_session_history
where session_id=511

We have not faced issue like this during Peoplesoft upgrade. what could be the reason that the status is not changing while the base sqls keep on changing after every 10 minutes.
I am trying use host command in Oracle forms. I get the process id as input from the user and on clicking ok the form should kill the session related to process id.
PS: Users will be entering only frmweb.exe process id which are inactive.
cmd := 'CMD /C taskkill /F /FI /pid 'process which is got as input' /IM frmweb.exe'; host(cmd)I also tried by writing the above command into a .bat file in application server.When trying to execute the bat file it din work. But when tryin to run the bat file by double clicking in Application server the session was killed.
On executing the above I am unable to kill the process. I would also like to know whether the host command was successful or not. Orakill and alter session are working but I don want to use it.

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?
View 9 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

The following link states

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

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 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);

On the oracle 11g, we see too many invalid sessions. Because of which, login is getting restricted. What do i need to do to kill those invalid session periodically, which will avoid of restarting of system.
