Limiting the number of users/connections

We currently have a very large user community (120000)who will be accessing the portal for ESS/MSS functionality.
We would like to limit the number of users to around 20000. Any more connections should get a nice error message (rather than a standard IE no more connections or a time out message).
We can obviously throttle the number of connections via the load balancer or via max connections in unix. Is there any method in the Portal itself, that will automatically direct the users to a seperate web page in the event of pre determined number of users/connections being reached.
I have search high and low but can't find a solution.
Thanks in advance
Fenton

Hi Tim,
No, there is nothing like this as a standard functionality within the portal. Similar requests are regulary asked on SDN (like: restrict the number of users logging in as you ask, restrict the number of parallel logins of one user, and things like this).
A possibility would be to implement your own login module which tries to check how many users are online. All techniques - independent if on portal or on WAS side - that try to count this have the problem that they cannot be sure who is "online" as you have no definite information if a user is online or not; one can only use more or less heuristic methods.
Hope it helps

Hi All,
Could anyone know , how to find the number of users connected to database without connecting with sql*plus
is there any command to find it?
example we have 10 databases in one server, how to find the number of users connected to particular database without connecting to database(v$session)?
oracle version:- 10g,11g
Operating System:- OEL4/OEL5/AIX/Solaris
any help will be appreciated.
Thanks in advance.
Thank you.

Excellent.
Tested, works as long as you set the ORACLE_SID first ( to change databases )
ps -ef | grep $ORACLE_SID | grep "LOCAL=NO" | awk '{print $2}' | wc -l
Thanks!

Measure the number of user connected to an Application

Hi,
How can I find the number of users connected to a weblogic application
Can you help me understand how can I measure this parameter for a monitoring purpose?
Thanks in advance,
Nicola Attico

Current Sessions is the current total number of open sessions for each application. Yes, you can use JMX or WLST within a script.
The WebAppComponentRuntimeMBean mbean of your application provides this information through OpenSessionsCurrentCount attribute.
For instance, in WLST enter:
wls:/my_domain/serverRuntime/ApplicationRuntimes/my_application/ComponentRuntimes/my_app> cmo.getOpenSessionsCurrentCount()
For JMX I suggest to you see [http://download.oracle.com/docs/cd/E13222_01/wls/docs91/wlsmbeanref/core/index.html]

Why does refreshing my web browser page increment the number of users connected to my Remote Front Panel?

Hi,
I'm using LabVIEW 2010 and a cRIO-9118 to broadcast my RT Front Panel on the web with a Web Server.
I successfully configured the web server to be able to control my Front Panel remotely. However, I have an issue with "Refreshing" the browser.
When I press "Enter" to search the adress of the web server, the number of users connected seems to increment by one and then tells me that "Too many users are connected to the front panel". Once this has been done, the only way to "unlock" the web server is to reboot the cRIO.
Is there any solution to avoid this behavior?
My current web browser is Internet Explorer 8.
Thank you

Solved!

Hi Mathieu,
Unfortunately, there currently isn't a very good solution for the problem you are facing. It seems like this is a known issue that R&D is working on. It so happens that in addition to simply refreshing, this issue also occurs if you try to access the Remote Front Panel using a second tab in a tabbed browser. One "fix" would be to invest in a higher count Remote Front Panel license. If that's not feasible, then the current recommendation would be to avoid connecting to the Remote Front Panel from a second tab or refreshing the view in your browser. Once you exceed the number of connections to the Remote Front Panel, you will have to restart the RT controller -- there isn't a way to change this default behavior. You can track any fixes by R&D by keeping note of the CAR (corrective action request) ID for this issue, which is #202702.

What limits the number of MII connections to Oracle.

We are using MII 12.0.5 and an Oracle database and are seeing errors in the logs to the effect:
SQL error occurred on connection jdbc:oracle:thin:@mii001:1527:SMD: code=0, state="null", message="Listener refused the connection with the following error:
ORA-12518, TNS:listener could not hand off client connection
The Connection descriptor used by the client was:
mii001:1527:SMD
I am ot an Oracle expert and I have not seen this issue before. What is limiting the number of connections? Is this a MII configuration issue that I am not aware of or an Oracle database issue?

Hello sparks,
I assume you are getting this error when you are trying to connect to databse while configuring Dataservers in MII,if fo what are the value you passed in the fields PoolMax and PoolSize while connecting to the database.

How to calculate the number of user connections in a report?

Hi,
I would like to have a report which automatically calculate the number of connections per user.
Thanks for your answer.

Hi,
What do you mean by number of connections? Do you mean how many times each user has run a specific report?
Thanks

How do I check the current number of users connected to the application?

Hi there,
I would appreciate that you advise me on how to know how many users are accesing
an application I've got in production, powered by BEA WebLogic Server 6.1.
In the Administration console, I go to the specific server, and inside the tab "monitoring",
then "Performance", I've got some graphics showing the memory usage and throughput.
But, where do I see the number of actual connection to the application?
Thanks

I am pretty sure that WLS doesnt give you the type of monitoring you require. You
might have to check out one of the third party monitoring partners like Wiley or
Precise.I guess that depends on how you define 'how many users are accessing' an
application(s) - for example, 'OpenSessionsCurrentCount' can serve as a rough measure of
the number of users currently using the web application. or, number of threads + execute
queue length can give you an idea of current number of user requests executing/waiting
to be executed at any given time, etc. WebLogic does provide lots of useful monitoring
information, and the fact that it uses JMX makes obtaining this information very easy.
Having said that I would like to ask a couple of questions.
a) what is your app (EAR? EJB's WebApp?)
b) why do you want to know, meaning as soon as you know how many what is the next
thing you want to know/see?
Cheers

Newbie question... Can I limit the number of users ...

Can I limit the number of users accessing a URL?
My company wants to start making videos available on our intranet web site. Once published, they are planning to send an email to all our employees (5000+) to announce the video. That's a great idea... but who asked the network guy if the network (server too) can take the load? NOBODY.
Short term solution... can I limit the number of concurrent users hitting a URL? And if possible, can I push a message to the users that try once the limit is reached?
Limiting the bandwidth is an option, but I will trash the user experience.
Long term solutions besides bandwidth increase? Cashing servers, WAN accelerators...?
Help !!!

This is really not a problem for the WSA to solve. Typically the WSA is used to control content and provide security for external internet content. The product does not have the feature you describe.
However, when it comes to the internal hosting of content - since you are using an internal server, that server should be able to control the amount of traffic it servers, number of connections, etc.

Is there anyway to limit the number of users?

Very straightforward, is there anyway to limit the number of users of the Airport Express for only a certain amount of time during the day?
There are certain periods during the day that I don't want my cousin to use the wifi, but the only way I can think of is to change the password and only type in the password for him when he needs it, however this is very troublesome? Is there a more sufficient way to do this?
Thank you.

You have the ability using Timed Access to establish daily time limits (or no time limits) for each computer that will be connecting to the AirPort Express.
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click Manual Setup
Click the Access Control tab located under the row of icons
For MAC Access Control select Timed Access
For complete instructions, click the Help menu at the top of the screen and then click AirPort Utility Help. Enter the following phrase into the search box:

Server Administrator has Limited the Number of Items You Can Open Simultaneously

Over the weekend, we moved all of our room mailboxes over to Exchange. For users who have lots of room calendars open in their Outlook clients, they are getting the error message "Cannot Open the free/busy information. You Server Administrator has Limited
the Number of Items You Can Open Simultaneously" after the migration from Exchange 2010.
Restarting the Outlook client temporary fixes the problem, but the problem comes back after they access the calendars again.
The users impacted deal with a lot of room scheduling, so they have 30+ room calendars open in their Outlook clients.
I have tried setting up a throttling policy with unlimited RCA connections, but that didn't help.
I have seen with Exchange 2010 there were some registry keys people were setting on the server that pretty much makes everybody have unlimited connections, but that isn't ideal if's only affecting a few people.

Hi,
Since this issue only occurs to a few users, I recommend you disable all the third-party applications on Windows, especially for the desktop search apps. Meanwhile, use Outlook safe mode to disable all the add-ins and check if the issue persists.
If the issue persists, you need to reset the value of Maximum Allowed Sessions Per User. Besides, we can't set it for only some specified users.
Here is a thread for your reference.
Event 9646, MSExchangeIS - Mapi session exceeded the maximum (Note: Though it is Exchange 2010, it also applies to Exchange 2013 about this issue)

How to find the number of ODBC connections to Oracle Database

Hi All,
How to find the number of ODBC connections and all connections to the Database in last week. Are there any views to get this information?
Thanks in advance,
Mahi

What Ed said is true that Oracle doesn't note which type of protocol is connecting to the database, however, you can see which program is accessing the database.
For example: if you already know of a user using ODBC, you can verify as:
select username, osuser, terminal, program from v$session where username = 'SCOTT'
USERNAME                 OSUSER          TERMINAL   PROGRAM
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
2 rows selected.Assuming that you can confirm the progam noted in the above (example) is the one using ODBC, then you can change the query such as:
SQL> select username, osuser, terminal, program from v$session where program = 'w3wp.exe';
USERNAME                 OSUSER          TERMINAL   PROGRAM
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
2 rows selected.Just for kicks, I checked our listener.log file, but there was no reference of odbc in it either.
Hope this helps...

How to limit the number of TCP connections beeing used concurrently while a page is beeing loaded?

We manufacture industrial small-footprint control modules with embedded web server. The resources of these modules are very limited, especially in RAM. We have problem, that FF opens 15 parallel TCP connections while loading a web page (main html page first, then all icons simultaneously). We can not handle such behavior because of lack of RAM memory needed for TCP buffers.
Question is how to limit the number of concurrent TCP connections the browser will use? We need to do it somehow directly from the page, we can not push our customers to change the general settings of their browsers (they would not understand such things anyway).
Do anyone have any suggestion?

Sorry, one other thought. Many web designers now combine all icons into a single image and use CSS to clip the image so that only the desired portion is displayed. This minimizes the number of required connections and increases the probability that the image can be retrieved from cache.

How we know the Number of users logged into stratus?

Hai,
How can we know the number of users logged into stratus? If we knows only,in our project we can check the users are valid/authenticated.can we check that?
Advanced Thanx

Stratus is adobe service which provides you with p2p id or say all your
application's users a p2p id. Adobe doesn't have any admin section where you
can manage/see all connected p2p users in your application.
This you have to implement at your end in your application code i.e.
authentication,validation and user counter.
Thanks,
Vivek.

Weird outbound problem = The number of vod connections are: 0

Hi all - I am a Verizon Fios BUSINESS customer, but their technical support has been of no help with this issue as I think I understand their routers better than they do.
I work from home in the Video Conferencing industry. I recently had trouble in my area that resulted in VZ replacing my older Actiontec router with a shiny new red one with the n speed wireless (MI424WR-GEN3I). Since that router was replaced I've been unable to initiate video recordings FROM my hardware video system in my office to my recording server on the internet. I had no problems whatsoever with the old router.
These recordings are initiated on port 443 and 554 TCP and then some high level UDP ports. It fails on my system and the message I get in the security log on the Actiontec is "The number of vod connections are: 0". Now, it's using RTSP (real-time streaming protocol) which perhaps the router thinks is video on demand and says that is a no-no? I don't know.
At this point I've tried everything - port forwarding, advanced filtering opening all IP between my VC system and the recorder - I even changed the remote administration from port 443 to 4430 because of something else I read. I can record locally no problem to a machine here on my LAN.
Lastly, I downgraded to the previous version of firmware just for kicks but no joy. Does anyone have ANY idea what the heck is going on?

I am sorry to hear about the problems you are having with your service since getting the new router. To see if it's router firewall issue, true putting the computer in the DMZ zone briefly to test. If it works in the DMZ, then we know it's a portforwarding issue.
