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
Mike

Report showing the number of active users in the system

All,
There is a standard SAP report which shows the number of active users in the system (output same as AL08).
Does anyone remember this?

Hello Bidwan,
Are you talking about the report RSUSR000?

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

Checking the number of concurrent user?

Hi all,
We are using FMS 4.5 to provide f4m & m3u8 live streaming and VOD to user via http.
How can i check the number of concurrent user connected to the live and VOD?
Many thanks!

A few random thoughts...
1) Check the system documentation for how RAM needs to be populated in the V240.
I seem to recall that platform needs them two-at-a-time.
2) Your prtdiag report would not have eight lines of information for the Memory Module Group unless there were eight DIMMs in existence. Empty slots would not be mentioned.
Use Google and search for a perl script utility named memconf_.
It's a handy third-party tool to get a text report of how RAM is populated in a system.

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

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

Create a new thread if you have a specific question, and create the thread in the correct forum. I'm closing this thread.

Visio 2010 Validation for Checking the number of a specific type of shape.

I have written a rule for flowchart for checking the number of Start/End Shapes in a document.
The FilterExpression is as follows:
AGGCOUNT(FILTERSET(SHAPESONPAGE(), HASCATEGORY("Start/End"))) > 0
The TestExpression is as follows:
AGGCOUNT(FILTERSET(SHAPESONPAGE(),HASCATEGORY("Start/End"))) = 2
(Since totally there are 2 shapes: 1 Start and 1 End Shape)
However, it is not working. Can anybody tell me what is wrong in the expressions.

Well, it worked for me, so I want to check that you modified the Start/End master to have the User.msvShapeCategories row with the value "Start/End", as I did?
A Category is not a Master

Is there a way to determine how many downloads have occurred on a professional account? We have multiple apps on the Apple and Android app stores and would like to know how many downloads from our first 5,000 have been used. Is there a way to view analytics from all of our apps at one time instead of having to log in to digitalpublishing.acrobat.com separately for each app?

I want to know whether we have any standard report , function module or tcode through which we can achive this.
A quick response will be appreciated.
Thanks in advance.

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

Limit the number of concurrent users

Is it possible to limit the number of concurrent users for the application in Websphere or at the http management level?

You don't say what version of Websphere you are using, but here's how you might limit the number of sessions in Websphere 4.0 Advanced Edition (other versions may differ):
Open the Administrative Console. Go down the tree to Nodes, Application Servers and click on the server you want to control (likely Default Server). In the right panel, click on the Services tab. In that panel, click on the Session Manager Service and click the Properties button. That pops up a new dialog.
Select the Advanced tab here. Put a number in the Maximum in-memory Session Count field and uncheck the Allow Overflow checkbox. Click OK, etc, etc, and you'll probably have to restart Websphere.
I said "might" because I don't know if this will do what you want or not. Read the help file associated with that dialog and judge for yourself.

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.

Are you using the Office for Mac 2011 version, as you need to do? The Office for Mac 2004 is Not at all compatible with Mountain Lion, and the 2008 version has been noted to have some problems running with ML.
Hope this helps

How do i check the number of licenses remaining from the volume license of Acrobat XI

We have purchased 8 licenses of Acrobat XI pro, and there is only one key associated with it.
Can anyone let me know, where can i get information regarding the number of licenses already in use, and MAC addresses associated to the PC in which its activated (if available)

It can be assessed through your internal monitoring system. However when you cross the number of activation count of the serial number, there is a prompt warning you regarding this.
Unfortunately it can not be assessed in licensing website.
