The number of active sessions isn't decreasing in OC4J instance

Hi Guru’s,
Could you help me, please?
The number of active sessions isn’t decreasing in OC4J instance after our clients closed the application.
Our partner use Oracle AS 10gR3 (10.1.3.4.0) with J2EE and HTTP mode.
When we monitoring our OC4J instance with Performance tab on Oracle EM, we appreciate that the value of Active Sessions on ‘Servlets and JSPs’ are very high. If users close our applications, then number of active sessions isn’t decreasing and active status isn’t becoming inactive.
Which OC4J settings responsible for managing active sessions and how can I get more information about the active session details?
Thanks in advance,
Zoltan

When I deployed this code Tomcat, it is giving the output as 0, hence tried with accessing the jsp file in multiple browsers but still it is showing the count of active session as 0 - plz helpPlease, don't resurrect old threads, and it's still the wrong forum. Create a new thread if you have a specific question, and create the thread in the correct forum. I'm closing this thread.

Check the number of active users of oc4j in EBS

Hi,
I often see a recommndation of sizing jvm's to 1 per 100 active users. How can I find the number of active users currently using a jvm in EBS. We have 4 apps servers and 1 of apps servers also runs OBIEE with it's own jvm.
I can find out from a unix command prompt counting establish connections to the port but I like to know if there's a better way to find the number of active users using the jvm's
Thanks
Mike

Hi,
To find the number of active user session on each of the application servers from a unix command line. I would find the port that Apache was listening on eg 8100. The use the following command on each of the apps servers
netstat -an | grep 8100 | grep -i est | wc -l
This gives a rough idea of how many active connections are established to the apps server. But I would really like to find how many users are actively using o4cj.
If you are using forms in socket mode again, you can grep on the forms listening port number to find how many active forms users are connected.
I can also see how many active connections are in the oc4j established to the database using lsof. Find the process id for oacore jvm.
lsof -p PID
But I'm sure there's a better and more accurate way of find active users of o4cj, specifically oacore.
Thanks

How to know the number of Active users logged in to a Essbase Application?

Hi,
Is there way to capture/log the number of active users who have logged into a particular Essbase application at a given time.
In Essbase or in Shared services?
I know we can see the EAS-Edit Sessions shows the actively logged-in users, then we can sort on the application/database & manually count the number.
Is there a way to capture it in a log at a given time on a regular basis. Any MAXL or Shared services feature?
Appreciate your thoughts.
Thanks,
Ethan.

You could use maxl .
display user all;
there will be a column called "logged in" which will display true/false for the users
but that will just show if they are logged into the server and not the application
You can also use use display session
display session all;
or
display session on application sample;
which should show what you are after.
Cheers

Why do the number of active JMS connections increase?

Problem
- Number of active JMS connections and current JMS messages increases until the Weblogic instances crash with an OutOfMemory exception
Setup
- Weblogic v9.2.3, Cluster with 4 Nodes
- A JMS Message is sent from a MDB in Weblogic to a distributed queue which has a member on each of the 4 Weblogic nodes. The session is created as follows session = connection.createSession(false,Session.AUTO_ACKNOWLEDGE), the message delivery mode is set programmatically to persistent and the delivery mode override of the queue setup is set to persistent too
- Standalone JMS client processes: each one is attached to all 4 nodes. Each one uses a unique JMS message selector so that we have more than one queue consumer for one queue but every message is exactly dedicated to one queue consumer. We us weblogic.jar for the clients.
- Use of Weblogic auto reconnect feature. JMS client code:
Connection connection = this.connectionFactory.createQueueConnection();
final WLConnection wlconnection = (WLConnection)connection;
wlconnection.setReconnectPolicy(JMSConstants.RECONNECT_POLICY_ALL);
wlconnection.setTotalReconnectPeriodMillis(-1);
wlconnection.setReconnectBlockingMillis(-1);
Remarks and Questions
- There are no pending JMS messages which is good
- In our setup, each JMS client is connected to all 4 nodes as the messages are not distributed to all nodes: if a message is put to Queue A but the client is only connected to Queue B, the message is NOT transfered from Queue A to Queue B. We set the parameter "Forward Delay" to 5 seconds with no effects. Is this the normal behavior?
- Not all JMS clients are visible in the Weblogic console under JMS Services -> JMS Servers -> [Server] -> Monitoring -> Active Connections. Which one are visible? Which one are not visible? There are also clients where the number of connections is not zero but stays constant; we know that as several independent clients on different hosts are started and the IP adress is visible in the Weblogic console. Why....?
- What reasons can lead to increasing connections? Is this due to client or server problems? Do we have to acknowledge the message in the onMessage(Message) method of the client JMS consumer? So far as I know, we don't have to.
- Are the increasing number of current messages due to the increasing number of JMS connections?
- May the RECONNECT_POLICY_ALL policy produce this problem?
Any hint is appreciated.

To answer the question about the forwarding of messages from one queue to another myself: As mentioned at http://forums.bea.com/thread.jspa?threadID=400000611, the forwarding for queues does only work if all queue consumers are attached to the same queue. This means that our setup is OK.
But the main question is still unanswered: why do the number of active JMS connections increase? I forgot to mention that
- all messages arrive at the clients and that no exceptions are visible in the log
- if you kill the client, the connections are still visible in the Weblogic console!?
Please help as this problem is very urgent.

[Forum FAQ] Restrict number of Active Sessions in RDS 2012 and 2012 R2

As everyone knows with the introduction of Windows Server 2012 & 2012 R2, there are various changes and no more availability for RDSH configurations or Remote Desktop Service Manager;
now we can manage all the settings under Server Manager and group policy.
Configuration 1: Remote Desktop Timeout settings:
Here, we will see the Remote Desktop timeout settings. You can maintain the settings under below mention path (Figure 1 and Figure 2).
Open the
Server Manager, select Remote Desktop Services.
In Remote desktop Services, in right side you can drop down to
collections.
Select the
collection which you want to edit the settings.
Under
collections Properties, select Task and then Edit Properties.
In Properties dialog box, select
Session.
You can find all the
timeout settings under session collection properties; edit according to your requirements and then
OK.
Figure 1: Selecting Collection Properties
Figure 2: Configuring screen for Timeout and reconnection Settings
Group policy setting:
The same settings can also be applied by Group Policy.
You can also configure timeout and reconnection settings by applying the following Group Policy settings, you can check the figure 3 for graphical view.
Set time limit for disconnected sessions
Set time limit for active but idle Remote Desktop Services sessions
Set time limit for active Remote Desktop Services sessions
End session when time limits are reached
In addition to this another group policy available with the help of which you can bale to set time limit for logging off the RemoteApp according to our desired time. This setting
can be applied with addition to above mentioned policy.
Set time limit for logoff of RemoteApp Sessions
These Group Policy settings are located in the following locations:
Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Session Time Limits
User Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Session Time Limits
These Group Policy settings can be configured by using either the Local Group Policy Editor or the Group Policy Management Console (GPMC).
Note:
These Group Policy settings will take precedence over the settings configured in Remote Desktop Session Host Configuration. If both the Computer Configuration and the User Configuration policy
settings are configured, the Computer Configuration policy settings take precedence.
Figure 3: Group Policy for setting Timeout and reconnection setting
Configuration 2:
Restrict & Enable user to a single & multiple session
Under Windows Server 2012 & 2012 R2, there is no specific setting under RDP-TCP as it is not available.
Restrict User to Single session:
To restrict the user to single session (Disable Multiple RDP Session) you can configure the setting under group policy (Figure 4).
Computer Configuration\ Administrative Templates\ Windows Components\ Remote Desktop Services\ Remote Desktop Session Host\ Connections
Restrict Remote Desktop Services users to a single Remote Desktop Services session     Enabled
Figure 4: Group policy for Restrict user to Single session
Enable user to multiple session:
To enable the user to multiple session you can configure the setting under below (Figure 5).
Computer Configuration\ Administrative Templates\ Windows Components\ Remote Desktop Services\ Remote Desktop Session Host\ Connections
Restrict Remote Desktop Services users to a single Remote Desktop Services session     Disabled
Figure 5: Group Policy for Enable user to Multiple Session
In addition you can also edit the registry setting for allowing multiple RDP session as per below (Figure 6).
HKEY_Local_Machine\SYSTEM\CurrentControlSet\Control\Terminal Server
fSingleSessionPerUser     REG_DWORD     0x00000000
Note: By default the registry value is set to 1, but you need to change to 0.
Figure 6: Display the registry settings
Also you can edit the policy “Limit number of connections” and set RD Maximum collection as per your company
requirements (Maximum limit: 999999) for above mention group policy path (Figure 7).
Figure 7: Group Policy for Limit number of Connections
Apart from this, if you have not specified any policy or registry setting and still you want to restrict the new session, then in Windows Server 2012 & 2012 R2 there is option where you
need to follow below steps (Figure 8 and Figure 9).
Right click a Remote Desktop Session Host in specified location of Host Server and select “Do not allow new connections”.
After clicking that it will ask you for your confirmation, click yes and no new connection will be allowed.
Figure 8: Setting displaying “Do not allow new connections”
Figure 9: Confirmation popup
RD Gateway Connection Properties:
If you have deployed RD Gateway under your environment you can also limit the number of simultaneous connections through RD Gateway by configuring
policy under RD Gateway Manager. For this you need to follow below mention path.
Open RD Gateway Manager, select the server which you want to modify.
Right click Properties.
Under General Tab
-Limit maximum allowed simultaneous
connections to:Specify the number of connection you want to able to provide connection.
-Allow the maximum
supported simultaneous connections:This
setting will allow maximum supported connections at a time.
-Disable new connections:This
setting will not allow new connections through RD Gateway but Active connection will not be automatically disconnected.
Select the option as per requirement which able to allow the connection
Figure 10: Connections setting under RD Gateway Manager
Configuration 3: Configure keep-alive connection interval
As per above mention in initial post you can able to change the setting for Keep alive connection interval. In addition to this also verify the
registry setting must be set as per following (Figure 11 and Figure 12).
HKEY_Local_Machine \ SOFTWARE \ Policies \ Microsoft \ Windows NT \ Terminal Services
KeepAliveEnable       REG_DWORD           0x00000001 (1)
KeepAliveInterval
REG_DWORD           0x00000001 (1)
Figure 11: Group Policy setting for Keep alive
Figure 12: Registry setting for keep alive
If you need further assistance, welcome to post your questions in our
Remote Desktop Services (Terminal Services) forum.
If you would like to achieve this in Windows Server 2008 or Windows Server 2008 R2, please move on to the next post.

Applies to Windows Server 2008 and Windows Server 2008 R2
Configuration 1: Remote Desktop Timeout settings:
1. Open the property dialog for RDP-Tcp connection in Remote Desktop Services Manager.
2. In the Sessions tab, you can configure the following settings:
Active Session Limit
Idle session limit
Action when session limit is reached or connection is broken
End a disconnected session
Additionally, you can configure the settings with the help of Group Policy also by below mention path.
Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Session Time Limits
User Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Session Time Limits
Configuration 2: Restrict each user to a single session
By using this configuration or policy setting, each user can only maintain one session to the certain terminal server; when another session is started by the same user, the original one will
lose the connection. In that way, the total number of possible active sessions won’t exceed the total remote users. You can implement this as below mention steps.
Remote Desktop Host (RDP-Tcp) configuration:
Edit Settings – Restrict each user to a single session: Yes
Group Policy: Computer Configuration\Administrative Templates\Windows Components\Remote Desktop
Services (Terminal Services)\Remote Desktop Services Session Host (Terminal Server)\Connections\
Restrict Remote Desktop Services (Terminal Services) users to a single remote session:    Enabled
Configuration 3: Configure keep-alive connection interval
By specifying the minutes that the TS holds a remote session actually disconnected, the server will detect the session status after each period. The session that are actually offline will
be changed to disconnected status:
Group Policy:
Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services (Terminal Services)\Remote Desktop Services Session Host (Terminal Server)\Connections\
Configure keep-alive connection interval:         Enabled and Specify the Value

Getting the number of active connections in a connection Pool

Hi,
I have an application deployed on jboss. DB used is db2. For monitoring purpose i need to get the number of active and idle connections at any point of time. I am trying to use commons-dbcp jar to get this data using BasicDataSourceClass. Following is the piece of code.
Context initialContext;
try {
     initialContext = new InitialContext();
     DataSource ds = (DataSource) initialContext.lookup(myjndiname);
     logger.info("************CONNECTION POOL DATA->" + ds.getClass().getName() + "************" + ds.getClass() + "**************");
     BasicDataSource bds = (BasicDataSource) datasource;
          logger.info("************CONNECTION POOL DATA-> ACTIVE CONN=" + bds.getNumActive() + " IDLE CONN=" + bds.getNumIdle() + " INIT SIZE=" + bds.getInitialSize());
catch (NamingException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
This code gave a class cast exception at the point datasource is cast to BasicDataSource. The class name returned by ds is WrapperDataSource. I have few queries on this:-
1. What configurations do i need so that datasource returned by InitialContext is BasicDataSource? FYI i tried to add the BasicDataSourceFactory in db2-ds.xml. But it still didnt work
2. Is there any other way to find the number of active connections in a connection pool? I dont want any server specific solution.
Pls help.
Thanks

How do I reset the number of activations on Visio 2003 after getting a "too many activations" message?

I just installed Visio 2003 on a PC, and got the "we can't activate this app via the internet because you've installed it too many times" message. I went back to phone activation, but, of course, that's no longer available for this product.
How do I get the number of activations reset? Apparently you used to be able to do this by calling Microsoft, but what's the number to call? Or is there another way to do it?
I'm probably going to need to do it for my copy of Office 2003 also.

Hi,
Microsoft has ended support for Office 2003 on April 8, 2014. This change will affect your software updates and security options.
Please contact your local customer service. Explain to the service (Human being) that you can’t activate Visio 2003 and the error message is “we can't
activate this app via the internet because you've installed it too many times”.
You can find
your local custom support number on the link below.http://support.microsoft.com/gp/customer-service-phone-numbers/en-us
Hope it can be helpful.

FF currently limits the number of open sessions

I currently programmatically launch FF on linux using an execl command. In the run string I use the -P option and launch my application by right clicking on the file that has its own mime type and that is opened by my app before the execl call. (my app takes a data file and creates a temp html file that is handed off to FF via execl) I check the system processes for a current running version of FF. If so I add the no-remote option.
This all works ok. However, if I attempt to launch another copy of my program FF will not allow this even though I am using a tab browser configuration.
I believe that one session of FF per "user" is acceptable but not the limit of one tab for each user other than the default user. I see my FF configuration eventually having several users as I begin to implement separate security policies for certain websites such as financial, casual, javascript development, no cookies, etc.
I typically keep well over 20 tabs open, if FF crashes I can loose everything as if the restore fails I must then hunt up each tab that I had open using history.
Can I get an update on where FF is headed with regards to the maximum number of users windows and the capability to open multiple tabs with a non-default user.

Sounds like you've got a connection leak - rather than increasing the number of open sessions, you need to constrain the application to use fewer!
If you don't ensure that the connection is closed even if an exception is thrown after it is opened but before it is closed then you are liable - likely even - to leak connections.
For example. Bad:
Connection c = getConnection();
... code here ...
c.close();Good:
Connection c = getConnection();
try {
... code here ...
} finally {
c.close();
}The same rule applies to ResultSet and Statement objects - and all three should be closed in the appropriate order (make sure you close result set and statement objects before re-using their reference).
(edit: rephrased ambiguous final para).

*IMPORTANT* Limiting the number of active threads

Hi All,
i have a few of questions so please bare with me:
1) What is the best way to limit the number of active threads? ie i want to run 10 threads but i want there to be only 3 running at a time.
this is how im thinking of doing it rite now:
count = 0;
while(...)
thread[count].start();
while(threadgroup.activeCount > 4){}
count++;
2) I have a class that extends thread how do i overide the constructor so that i can add the thread to the threadgroup?
ok here is an example of what i mean:
u can do this with a normal thread: Thread one = new Thread(threadgroup, "what");
this is what i need to do tho:
class whatever extends Thread {
public whatever(int a, int b, ThreadGroup tg)
{ what do i put here to make this thread part of the tg threadgroup?}
thanx for any help in advance and i kinda need a quick answer cause this is due soon , thanx youssefe2k4

Hi,

/KajIt's part of a homework assignment... I saw another post on this forum and one at JavaRanch where you need to create an application that given a directory will scan each file and report the file name and how many lines are in them... but it must be multithreaded, each thread scan a single file and updates some list and finally you can only have three of these file scanning threads running at the same time...
Quote "To avoid having too many threads competing for the system resources when there are a lot of files in the directory, we will restrict the number of active Producer threads (active threads are started threads that have not ended yet) during the run time. For this assignment, at any time there should not be more than 3 active Producer threads. If there are already three active Producer threads during the run time, the program should wait until one of them ends to start the next Producer thread."
I was think about working on it, so that I can strengthen my knowledge in threads...
I still might do it, just for fun... I don't know yet...
We will see...

Monitoring the number of active calls in a gateway from HUM

Hi,
we are configuring HUM and we want to display the number of active calls in a gateway but we can't find any OID's that show exactly what we want. So we are going to use the EXPRESSION-MIB in order to calculate some values we need.
In MRTG we launch a snmpwalk query against the OID 1.3.6.1.4.1.9.9.63.1.3.1.1.9 (cvCallActiveInSignalLevel) and we count with a counter the number of rows obtained from that snmpwalk. The calculation is as follows:
@ret=snmpwalk(sigint03.'@'.'x.x.x.x'.'1.3.6.1.4.1.9.9.63.1.3.1.1.9');
foreach $campo (@ret) {
$cuenta=$cuenta+1;
print $cuenta."\n";
But we don't know how to implement the "foreach" loop with the EXPRESSION-MIB... and we don't know any other way for getting the number of active calls.
Can anybody please help me?
Regards.

How to check the number of active jdbc connections

hi all,
i'm creating a connection from Java using java.sql.Connection class and with oracle thin drivers. connection is creating properly.
now, i want to know how many connections are created, through the sql query. i forget the query.
its helpful for me.
regards
pavan.

Your requirements are a bit vague - the only place to accurately determine the number of connections is in Oracle using the V$SESSION virtual view.
It can tell you the number of session (active or idle) made from the platform running that Java code. It can also tell you basic session information like the current SQL (if active) that is being executed.
There are numerous other V$ views that can be used in conjunction to build a very accurate picture of what the session is doing and what resources it is using.
Details are in the Oracle® Database Reference manual. On-line copies of all manuals available via http://tahiti.oracle.com

Any way to get number of active sessions

Hi,
 With the deprecation of the HttpSessionContext interface as of Servlet API
 2.1 for security reasons, is there any way to know how many sessions are
 currently active in a given WebLogic instance?
 Thanks,
 Sanjiv


You could make it a singleton. The overhead is nothing ... trust me. Run
 WebLogic through a profiler if you don't ;-)
 Good luck,

Limit Number of active sessions for wlan user in Cisco Prime

Is there a way to limit the number of logins from a particular set of credentials in Cisco Prime 2.1? I want to set a maximum of 2 logins from a particular user on the wlan. I have a guest wlan using layer 3 security and an internal wlan using RADIUS (Windows). Would appreciate the help

There is, but it isn't due to PI. It is a function of the WLC itself.
Under Security, there is a Concurrent User Login, set to 0(which is default) it is unlimited logins. This value can be changed to be the number of concurrent logins that work for your situation.
Be advised, this is not a Per WLAN setting, it is a controller wide setting.
HTH,
Steve

The number of active sessions isn't decreasing in OC4J instance
