How to know active sessions logged in by same database users

This is 10g. I need to query list of DB users who have logged in using the same database user accounts. How can I achieve this? This is on 10g and 9i

Hello,
You may enable audit. Then, with the following query you may get the list of User who logged on the same Oracle User account:
select username, os_username, userhost, terminal, timestamp, action_name
from dba_audit_trail
where action_name in ('LOGON','LOGOFF')
order by username;Please, find below a link about audit:

Hope this help.

How to find active sessions count on a server in weblogic server console

Hi All,
I would like to know how to find active sessions count on a server in weblogic console. I am using weblogic 11g.
Regards,
Sunil.

On the deployment, monitoring tab, you can select web applications. Here the number of current sessions are listed per web application deployed on the domain.
The deployment itself (deployments, application, monitoring, sessions) shows a list of sessions and where it is located. Unfortunately, there is no aggregation (but that is something you can so yourself as well).
When you are using a load balancer in front, the count of sessions on per web application on the domain gives you some clue how many sessions there are present on each server.
That is to say, when load balancer is using round-robin (and does that correct), you can take the total number of sessions divide it by the number of servers.

How to know active user in Ad ? & how many days from not use user id ?

How to know active user in Ad ? & how many days from not use user id ?
Thanks & Regards, Amol . Amol Dhaygude

Hi Amol,
You can use the below command from the command prompt of DC to get all the AD users who are inactive for last
X weeks,
dsquery
user -inactive X
To extract the inactive user information to a CSV file use the below command,
dsquery user -inactive X > c:\TestFolder\InactiveUsers.csv
NOTE: The value
X represents number of weeks, for example if your requirement is to find the inactive users for last 90 days then the
X value should be 13.

How to access "Active Sessions" using MBeans

Hi all,
I have deployed an application at EM (Enterprise Manager).
when I logged into EM and click the application I can see the number of active sessions under "Servlets and JSPs" topic.
how can I access that parameter at application level..??
(I want to access that parameter *"x"* at my web application and display Logged in users : x )
EM shows that the number of active sessions. it updates too.. so there must be some bean or record for that parameter..
how can I access that....??

Knowing active Session id

Hello,
Is there a way to determine what are the active Session IDs in DI Server?

Hi Yatsea,
Still remember me? We both meet in Malaysia last year which you held an Advance training in SDK. How are you?
About the DI Server, when I'm gonna logout the Session ID, a fault message appears "SESSION ID IS IN USE", which is currently processing a document. I just want to know how to view all the active session ids without using arrays so i can easily avoid duplicate documents.

How to get active session details

Dear all
in my application i want to display number of users online in a list and their details,for that how can i get the active session details in a jsp , or any other ways to do this.any suggestion regarding this is very much helpful to me. thanks in advance
thanking u
yours
kumaran ramu

Hi,
You can use a Listener class for track the sessions and do some logic when a session is created/destroyed. See HttpSessionListener interface. You can save the session IDs and session objects when a session is created, for example in a hashmap. Save the hashmap in application context. In your JSP get the hashmap and get its key/values. See thread safe problems if you are using a hashmap in application context.

How to monitor active sessions in a cluster

Hi all,
we currently test failover of our WLS 11g cluster.
How can I see in the Console to which managed server a client is connected?
Thank you in advance
Regards
Rolf

today i found a way to get the name of the server in a cluster which handles the active session, using a managed bean in my application.
There i added a getter method
public String getServerName() {
return System.getProperty("weblogic.Name");
and then I used an af:outputText with
#{<mybean>.serverName}
See this blog entry http://theblasfrompas.blogspot.com/2009/05/adf-failover-within-weblogic-103.html
Is there realy no way to get something like client-ip:<managed server> using WLS console?
I only found the number of requests (which is incrementing after reloading the console) in Deployments-> <application> -> Monitoring - Workload
Regards Rolf
Best Regards

How to display active Session ?

hi,
i would like to implement for an administrative usage, a jsp page that list all active session. I notice in the J2EE api that there's a HttpSessionListener interfaces wich enables listener to receive notification when creating and deleting session. Is it a good way to implement this functionnality, thanks in advance for your help.
PS : i am sure, others persons have already implement a solution, perhaps there is a Design Pattern for that.

Hi ,
Its really simple....
See the following code
public class SessionCounter implements HttpSessionListener {
int sessionCount = 0;
public void sessionCreated(HttpSessionEvent evt) {
sessionCount ++;
evt.getSession().setAttribute("Count", sessionCount);
public void sessionDestroyed(HttpSessionEvent evt) {
sessionCount --;
evt.getSession().setAttribute("Count", sessionCount);
now add this Listener to your web.xml
and you can get it anywhere (in jsp or servlet) using session.getAttribute("Count");
Is this you want.
Please let me know.
cheers

How to know Active or open ports on a system

How to know he open ports on a system.
N e idea.
regards,
Rajesh Vincent.

Using the Java Communications API you can use the static method CommPortIdentifier.getPortIdentifiers to enumerate the available ports on the system, like:
Enumeration ports = CommPortIdentifier.getPortIdentifiers();
while (ports.hasMoreElements()) {
CommPortIdentifier port = (CommPortIdentifier) ports.nextElement();
switch (port.getPortType()) {
    case CommPortIdentifier.PORT_PARALLEL:
      // it's a parallel port (called port.getName())
      break;
    case CommPortIdentifier.PORT_SERIAL:
      // it's a serial port (called port.getName())
      break;
    default:
      // WTF?
      break;
}To know whether you can open the port I think you can use the isCurrentlyOwned() method. To open the port use the open(java.lang.String appname, int timeout) method (you'll get a PortInUseException if the port is already in use)

How to know which session id has acquired an object ?

Hello,
We work on database 11.2.0.2 and aw 10G style.
concurrent users attach an aw in multi mode.
They make update on cubes and on dimensions.
They use the olap command Acquire before update changes.
When an object cannot be acquired, i would like to know which session lock this object.
best regards
jean marc

That's an interesting question. I'm surprised that nobody has asked it before. The following query will identify all sessions holding object locks:
select a.aw_name,o.obj_name objname, e.sid sess_id
from dba_aw_obj o, gv_$enqueue_lock e, dba_aws a
where
e.type='AO' and
o.aw_number=e.id1 and
a.aw_number = e.id1 and
bitand(o.obj_id, 1073741823) = e.id2;

How to remove the selected owned schema in a database user in security

Hi all,
I am using SQL Server mgmt studio with 2005 db. I accidentally clicked the

remove the check boxes they were greyed out. How do I remove them?
Regards,

go to the schema > choose the schema which is disabled for the user > properperties > change the schema owner = schema name
I you want T-SQL then use below (change the greyed out schema name)
USE [DatabaseName]
GO
ALTER AUTHORIZATION ON SCHEMA::[db_owner] TO [db_owner]
GO
