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 find if an user account is locked in weblogic server or not?

Hi,
I am using jdev 11.1.2.2.
SO i have set in web logic that if a user inputs login information wrongly his account will be locked.
How can i identify if the user account is locked.
Write now if the user account gets locked after say five invalid login attempts and user tries to enter correct login information its throwing exception . But i want to display to the user that his account is locked instead of the exception being thrown . How can i do it ? the following the login code i use
    public String doLogin() {
        LOGGER.log(ADFLogger.TRACE, "Clicked Login Button");
        LOGGER.log(ADFLogger.TRACE, "doLogin() Started.");
        String un = _username;
        byte[] pw = _password.getBytes();
        this.setPassword(null);
        FacesContext ctx = FacesContext.getCurrentInstance();
        HttpServletRequest request = (HttpServletRequest)ctx.getExternalContext().getRequest();
        try {
            Subject subject = Authentication.login(new URLCallbackHandler(un, pw));
            weblogic.servlet.security.ServletAuthentication.runAs(subject, request);
            String loginUrl;
            loginUrl = "/faces/home.jsf";
            HttpServletResponse response = (HttpServletResponse)ctx.getExternalContext().getResponse();
            sendForward(request, response, loginUrl);
        } catch (FailedLoginException fle) {
            FacesMessage msg =
                new FacesMessage(FacesMessage.SEVERITY_ERROR, "Incorrect Username or Password", "An incorrect Username or Password was specified");
            ctx.addMessage(null, msg);
        } catch (LoginException le) {
            reportUnexpectedLoginError("LoginException", le);
        return null;

Active session count of an user

Hi,
Could you help me understand the concept of active user session count and the factors influencing the active sesssion count of an user
1) Does running multiple queries in a number of query windows in SQL developer lead to increase active session count?
2) Does a high degree of parallel option ( e.g. Parallel (Degree 8)) provided in a query lead to a higher session count?
3) Does the size of data processed in a query influence session count?
4) Does the complexity of a query influence session count?
5) Can a session remain active even after completion of a query and thereby increase the active sessioncount?
Regards

Does the client use some form of multi-threading? If so, the client needs a separate and active Oracle session servicing each of its running threads.
The user may only initiate a single connection to the database - but the application remembers the authentication and connection details and can transparently establish multiple additional sessions. (a common behaviour by TOAD and SQL-Developer)
1) Does running multiple queries in a number of query windows in SQL developer lead to increase active session count?Yes - as an Oracle session is serialised. It can only execute a single client request at a time. Thus if the client has 3 windows/tabs with each running a SQL query - then 3 Oracle sessions are required to service that client.
2) Does a high degree of parallel option ( e.g. Parallel (Degree 8)) provided in a query lead to a higher session count?No. PX slave processes are database processes. They only "assist" a session at specific times. Then they can "assist" other sessions with other parallel query processing. The database has a configurable PQ processing pool of processes. You can specify the minimum number of processes to create in the pool at startup. You can specify the ceiling of the pool.
So no number of sessions can grow the number of PQ processes beyond the maximum size of the pool. And the pool is there to service all sessions. Not just a single session.
3) Does the size of data processed in a query influence session count?No.
4) Does the complexity of a query influence session count?No.
5) Can a session remain active even after completion of a query and thereby increase the active sessioncount?This is default behaviour. If that session terminates, the client looses its database connection.
In the case of a multi-threaded client, it can decide to close one or more of the transparent "background" sessions it created to the database, when no longer needing such a session. However, it will keep its initial (first) session open as its primary connection to the database.

How to find the sessions which generated maximum redo amount at instance?

I use below query or Sql*Plus's set autotrace traceonly statistics > redo size statistic to calculate how much redo I generated in my session;
CREATE OR REPLACE VIEW redo_size AS
SELECT value
FROM v$mystat, v$statname
WHERE v$mystat.statistic# = v$statname.statistic#
AND v$statname.name = ‘redo size’;
But how to find the sessions which generated maximum(top 5 for example) redo from the last database startup on 9iR2 or also with new 10gR2 historic views?
We need this information because from the produced archived log files we observe something new producing almost 2 times more redo for a week. I looked at statspack report but couldnt find as I suspected for a massive update or delete.
Best regards,
Tonguc

I tried v$sysstat but I didnt think about v$sesstat Mr.Gasparotto, thank you very much :)
SELECT ss.sid,
sq.sql_text,
se.status,
se.username,
se.osuser,
se.program,
se.machine,
ss.VALUE
FROM v$sesstat ss, v$statname sn, v$session se, v$sqlarea sq
WHERE ss.statistic# = sn.statistic#
AND se.sql_hash_value = sq.hash_value(+)
AND se.sql_address = sq.address(+)
AND ss.sid = se.sid
AND sn.NAME = 'redo size'
ORDER BY ss.VALUE DESC
Best regards.

Active session count of ASA in HA

Hi,
We have configured our ASA5540 in active-standby failover.
We are observing that current active session count is twice of session count before configuring HA. Earlier average active session was 50000 and now after HA it is around 100000. Kindly let us know the reason for same.
Failover configuration of both firewall are as follows
failover
failover lan unit primary
failover lan interface FOLan GigabitEthernet1/0
failover polltime unit 15 holdtime 45
failover replication http
failover link StateLink GigabitEthernet1/1
failover interface ip FOLan 10.3.3.1 255.255.255.0 standby 10.3.3.2
failover interface ip StateLink 10.4.4.1 255.255.255.0 standby 10.4.4.2
failover
failover lan unit secondary

Hi,
I guess you have check this with "show conn count" or "show conn" commands on the ASA?
Ofcourse the first thing that comes to mind is that its somehow adding up the connection count of both ASA units. Though it shouldnt do this to my knowledge. You should just see almost equal amount of connections on both units. Both Primary and Secondary.
Have you tried to check if there is any host on your local network that would be taking alot of connections? Maybe somethings happened at the same time (even though it might not be likely)
Have you noticed any performance issues/problem after this upgrade to a A/S ASA pair?

How to upload and download any file from plsql through weblogic server

hi all,
how to upload and download any file from plsql through weblogic server? i am using oracle 10g express edition and jboss.
Thanks and Regards,

hi bala ,
for a windown server u can use VNC (virtual network connection) which opens a session on u r desktop later u can drag and drop form there vice versa and for a linux box you can use Win SCP which helps to open a session with interface to u r desktop in both cases you can upload and down load files very easiy just as we drag and drop items in a simple pc .. we use the same technique...

How to find out reports count

HI,.
I've doubt that how do we know the no .of reports in webcat.. Let's say i hae copied the web at from prod today, if the businees add new reports . how to find the count of the reports .

Hi,
go to answers, there is search option..
type * and search..
along with the report names, it'll give count also.. like: Search resulted in 3393 items.
Search count can be restricted to particular folder also, Select folder from left then type * and search..
But, this count will be only on reports.. it omits prompts..

How to find a session with high archive logs

Any query, to see which active session is generating high archive logs in oracle 8i &9i and high rbs usage

Though, there is no direct option or view where you can get this information.
However, you may can find out the session which are generating lot of redo and undo. I guess, when the session has lot of redo & undo, definately, it contribution towards archive would be more.
You can query v$sess_io and v$session to findout the the session which is generating lot of redo. i.e. lot of block changes occuring.
SELECT s.sid, s.serial#, s.username, s.program, i.block_changes
FROM v$session s, v$sess_io i
WHERE s.sid = i.sid
ORDER BY 5 desc
Also query v$transaction and v$session to find out the session that is generating lot of undo information.

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 find active master data source in the bw system

Hi
Can anyone guide me how to find the active master data source in the bw system

Hi,
You can use the table ROOSOURCE. The field ROOSTYPE specifies the type of datasource whether Transaction or attributes or text. You could write an abap program to filter the table and give you only master data datasources.
Assign points if helpful

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

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....??

How to find out Sessions in weblogic server

Hi all,
i am new to weblogic and i am struck at these two questions while creating managed servers. Many people questioned me regarding this. Can you all please help me out.
1)Before adding a MS , how can we figure out the current load and what would be the impact/benefit be if we add a MS.
2)How many sessions can be handled by the unix Weblogic server?

HI,
The answer of These kind of questions can be found only after the Load Test on the WLS. Because there is no formula to calculate these things. Because these things totally depends on various different things....Like Operating System, It's RAM, CPUs, JDKs, Application type(EJB, WebServices, Portal, Simple WebApp), Number of Users, The Physical Distance of ManagedServers and DataBases....Network Conjunction...etc
So no one can tell here the exact value. But for performance diagnostics you can refer to *"René van Wijk"* best article to find out these things using small tests as described in the following Link:
Topic: Performing Diagnostics in a WebLogic environment

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
