No of Concurrent Sessions Per User Mismatch with profile settings

Hi
DB Version Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
OS RHES 5U2
I created a profile MYPROFILE and set the value of Concurrent Sessions (Per User) to 30. DB was bounced after creating the profile. I made this profile default for a particular user "MYUSER". I verified that by querying DBA_USERS (select profile from dba_users where username like 'MYUSER') I checked v$session with that particular user after sometime and noticed that it was showing 34 sessions. Some ACTIVE and some INACTIVE.
My question is, if I have set the maximum limit of concurrent sessions per user to 30 in myprofile and made this the default profile for MYUSER, then how come i am still able to see more than 34 sessions of myuser regardless of the status? I am not sure if this is relevant or not but the IDLE TIME is set to 15 minutes.
Thank you for your help

Thank you for your helpDid you set the parameter resource_limit=true ? You must do it before you test sessions_per_user. You can do so like the following,
alter system set resource_limit=true;After this again try and post the feedback.

Limit the number of session per user in the Wired dot1x environment with ISE 1.2

Hello,
I need to check if there is any configuration/workaround to limit the number of sessions/access per user in the Wired dot1x configuration.
I need to check if this feature is available or not to solve the following scenario:
I have 2 SW ports configured to use dot1x authentication with ISE 1.2 server.
If user A connects to the 1st port and authenticated then he will placed on a VLAN based on the authorization profile.
The case, that I need to deny the same user to connect on a different machine with the same credentials.
The ISE itself does not have this feature currently, the only feature available is to limit the number of sessions for the guest user.
Is there any workaround on the Cisco switches to solve this? Cisco WLC has this feature and for the VPN we can limit the number of sessions also from the ASA itself.
Thanks.

limit number of session per user using wired dot1x is not available in 1.3

Single Database Session Per User in ADF/BC Application

Hi, I am using ADF with BC (JDeveloper 11.1.1.1). My application contains multiple application modules, each connected to the same JDBC data source. On the app server, I have configured the data source to use Identity Based Connection Pooling.
My current configuration is resulting in numerous database sessions for each user. I have a requirement to use only a single database session per user HTTP session. Is there any way to configure the application modules to achieve this?
Thanks,
Brad

Hi,
use a single root Am module and make sure the others are used as nested modules. This will create a single connection

How to realize only one identical remoteApp per session per user per computer?

If a terminalserver 2008 R1 is configured for only one session per user, everything works like it should if the user connects using the 'normal' remotedesktop session. A second connect with the same credentials kicks the first connect.
If a remoteApp is used instead of the 'normal' connect, it's possible to start multiple instances of this app within one user a least from one computer. mstsc do run multiple times and seem to link in the existent connection without kicking it. How to change
that?
Continuative:
The started RemoteApp checks the mutex of all started processes and stops herself if a process is found with the same mutex. This prevents multiple instances of this app within one user with the same sessionID. If a terminalserver is configured for only
one session per user, this RemoteApp shouldn't start multiple within one user. Using a "normal" remote desktop session the app doesn't start more than one time, I tested it. Used as RemotApp, the app starts multiple! Possibly I'm able to change this behaviour
with a code fix instead of configuring terminal services. Any tips regarding mutex and terminalservers?

Hi,
I tested the following code and it is working for me both in a RemoteApp and Full session:
Imports System.Threading
Module Main
Sub Main()
Dim createdNew As Boolean
Dim m As New Mutex(True, "TPMutex", createdNew)
If Not createdNew Then
Return
End If
Application.Run(Form1)
GC.KeepAlive(m)
End Sub
End Module

Clustered WL 6.1 creates 2 server sessions per user

          It appears that WL 6.1 creates 2 HTTP sessions per user for a simple JSP object.
          It shows in "ADmin Console/mydomain> DefaultWebApp> Web Applications> DefaultWebApp>
          Servlet Runtimes":
          1 /count.jsp
          1 /*.jsp
          In a non-clustered environment this does not happen.
          Is that normal?


I found the problem myself. For some reason WL did not like any special characters in the system password. I am not sure which ones are valid and which are not but I am avoiding them all right now.

Maximum Number of Sessions per User

I am using OAM 11.1.1.5.0 running on Solaris 10. When we change the "Maximum Number of Sessions per User" to 1 (per customer requirement), a user is restricted to having one active OAM session at a time (as expected). However, if the user does not explicitly log out (e.g. they just close their browser), they are unable to log back in to OAM until their existing OAM session times-out/expires. Given the above max sessions of 1 requirement, is it possible to config OAM to auto-kill the user's session and create a new one if they attempt to login before their initial OAM session times-out/expires? This was possible in Sun's Access Manager. Is it possible in Oracle's OAM? Thank you in advance for your reply.

R12 Restrict Parallel Concurrent Requests Per User to a Limit.

Hi everyone,
Is it possible to restrict parallel concurrent requests per user to a limit.
e.g. UserA sending concurrent requests to submit 15 heavy reports one after another. After 2 minutes he feels free. Now 15 reports running in parallel are heavy enough to take system's performance down. Is there a way to restricting parallal reports by a single user to 5.

Flex connect with a per user ACL with APs locally switched

Hi all,
Does flex connect allow a per user ACL to be downloaded to the session with local switched, central authentication? We are using ISE for the central policy engine and have setup dACL for wired but am about to embark on WLAN. The controller is a 5508 and the. APs are 3700's.
Second question- if the flex connect APs don't do any form of per user ACL, the other option is to have the units in regular mode where they are both centrally switched and centrally authenticated which I understand to support a per user ACL. Our WAN links are between 10mbps - 30mbps and the most latency would be around 40ms. Will this cause issues at all with the size WAN links and latency?
Thanks
Sent from Cisco Technical Support iPad App

Well you are running v7.6 so FlexConnect per user radius ACL's are supported per this doc since v7.5.
http://www.cisco.com/c/en/us/support/docs/wireless/5500-series-wireless-controllers/112042-technote-product-00.html#anc9
As far as WAN latency, 200ms is good, but it depends in your WAN utilization now and how many AP's you plan on installing and the increase in wireless traffic across your WAN. There is a minimum requirement, but it's up to you in the end to make sure you have enough bandwidth or else you will need to QoS the capwap traffic to ensure the APs don't bounce from connected to stand alone.

Q: Count concurrent sessions per hours in a specified interval

Hi,
I have this table wich contains SESSIONID, CREATEDATE, LASTCHECKDATE, EXPIREDATE, PARTNERID
We need to make a query that would return the number of max concurent session per hours for the interval specified.
For example, for last week, on a per hour bases, or day bases, the top concurent session for each hour or day depending on the report.
can do the number of new session on each hour with this query;
SELECT TO_CHAR(createdate, 'YYYY/MM/DD HH24') ||'h ' start_time, COUNT( SESSIONID ) new_sessions, name || ' {' || partnerid || '}' as Partner
FROM uws
WHERE expiredate IS NOT NULL
and partnerid=25
and TO_CHAR(createdate,'YYYY/MM') = '2010/05'
group by TO_CHAR(createdate, 'YYYY/MM/DD HH24') ||'h ', name || ' {' || partnerid || '}'
ORDER BY 1 DESC;
I think I should use MAX(count(sessionid)) and probably some DECODE when c1 between createdate and lastcheckdate...
This would need to run on sqlplus from a shell script if possible and even chart it on Google Charts.
Any help appreciated, note that I am not an Oracle expert..

Now the output seem to produce the concurrent sessions as needed but the date range show is not exactly.
I expect the output to display only for the range specified in parameter, which if for this example only one day.
Probably if we ask for more that few days, we would like to display the MAX number of concurrent session for one day and the average (optional) also for that day and this for all days in the period.

No session per user

hello
our application uses UIX + BC4J (jdev 9.0.5.2)
we are using JAZN for authentication through Oracle OID
How can i prevent a specific OID user from loggin more than once to the application... I cannot use Oracle profiles as Oracle profile use database users. All our users have the same URL in JDBC and hence the same database user
please help

Hi,
U can do that with Profile.
Check the table dba_profiles, u'll find SESSION_PER_USER in the
field RESOURCE_NAME.
If u want different value for each user, make one profile by
user.
Bye,

Session per user = 1 is not working in database ?

Dear All,
A profile has been configured on database with parameter session_per_user=1 but it is not working on database.

Please sugeest the solution .....

Can't limit the number of simultaneous sessions per user

Hi,
I am using Cisco ACS 4.0 as a radius server that authenticate users for Internet access.
Microsoft ISA 2004 is used as Radius client.
When users tries to connect to Internet, the ISA Server forwards requests to Radius server (Cisco ACS) for authentication.
I have constated that some users communicates their passwords to permit acces to Internet for non authorized users.
Even, I have selected Max Sessions property in Cisco ACS to 1 for every user, I can see clearly on ISA 2004 that the same user/password is used from multiple PCs simultaneously.
Internet acess on my company is based on a user / password authentication, and IP adresses are provided by DHCP server.
Can you help by advising me how to limit every user using the internet to only a single session at any time, by using ISA 2004 (proxy) and Cisco ACS 4.0 (Radius Server).
Thank you.
Mustapha.

Limiting every user using the internet to only a single session at a time is not possible with a radius server. You will need to use the proxy server (ISA server) for this task.

Single session per user

To demo my product, I put usernames and passwords right on the login page. I don't want people getting confused by the result when the same user is trying to do two different transactions, so I'd like to restrict each username to one session at a time. If someone tries to login with a username already in use, I need to reject their login.
Is there a way to do this?
Thanks.
Bill

Bill,
Better keep that PayPal account up-to-date. Sounds to me like you don't want SQL executed within any HTML DB session to be able to delete/update the same rows in tables or insert new rows when the timeframe between session creation and logout (or the final page visit of the session, e.g., user closes browser) overlaps with the similarly bounded timeframe of another HTML DB session.
HTML DB can't help you with this, there is no concept of an "active" session or "session in use".
You'd have to do something like insert a row into an ACCOUNT_IN_USE table when one of your accounts is "logged into", then delete the row when the logout takes place. Insert the row using a new process on the login page (raise error on dup key) and delete the row when the user clicks a logout link that should take them a logout confirmation page, which when submitted, deletes the row and redirects to the logout URL that you currently see in the Logout navbar icon. Replace the target of that navbar icon with a link to your new logout page. And then manually run a reset procedure to delete all the rows after so many users have not "actively" logged out but just closed their browsers and went home.

2. The same employee click the "Shop" link and a 2nd. session is created for the same user !
3. The same employee click the catalog link (CCM) and a 3rd. session is created !
Anybody knows how to solve this ?
Thank you !!!
Kind regards,

When you logged in first time, it creates one session.
But after that if you navigate to different transactions it shows in the second session.But it does not open new session for each link(ie Shop, confirmation, etc). Instead old session closes and new session opens.
When it comes to CCM, obviously new session opens as you are connecting to new application by keeping open the existing one(Shop).
But how does it matter to your application?
Does it show any impact on the performance?
