Concurrent Users in OBIEE

Hello,
How can we set the number of concurrent users who will use the OBIEE application?
Thanks in Advance.

There is a setting in the Repository for the connection pools for maximum concurrent users.

How do you set maximum number of concurrent users to OBIEE

In a training session for the end users - only 4 users could connect - after this others could not connect - got NQS Error:100118 Access for the connection is refused

As I don't see any configuration tag to specify concurrent users.
Try this, go to connection pool (within RPD) and set the maximum number of connections, this does correspond to number of concurrent connections to database but not concurrent users.

Concurrent user sessions

I want to restrict concurrent user sessions to one in weblogic server console. we are using OBIEE 11.1.1.5.
At a given point of time the user should have only one login session. if user logs in through other computer, his/her previous session should logoff.
Is there any way to do this other than using OAM/OID?

hi
it is impossible to do reliably, this question is raised from time to time. Also I recommend you to double check your architecture: by restricting concurrent user sessions you play against web rules which in most cases is caused by fundamental problem of
the architecture. Your solution with app variable will work only on all-in-one server, on farm it won't work for example. So I suggest to check architecture instead of continue working in this direction.

Find the number of concurrent users in system at a given time

Hi All,
We have the ECC system in which we need to set up monitoring alert which should tell the following things.
1.The number of concurrent users looged currently in the system.
2. List of transaction per hour or user activites with the counts
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.

Santosh

Dear Santosh,
for concurrent users there is this monitor in RZ20:
   System Configuration
       Operation Mode Status
       Instance Status
       Concurrent Users
           Concurrent Users (all Clients)    2 Usrs, Green 15.05.2014 , 17:02:18
           Concurrent Users (Client 000)     1 Usrs, Green 15.05.2014 , 17:02:18

Perhaps a search on google will find your answer.

Load testing with concurrent users on HTTP Web

Hello,
I am trying to do load testing my PHP Web Application.
I record (with Firefox) and developed the testing script with OpenScript,
but I found that I could only test with "Iteration" feature.
Is there any way to do load testing with concurrent users ( multi users login at the same time ) which defined in databank?
Thanks for help.

Hi
You need to load the script into OLT (Oracle Load Testing) you can download it from here you need the first link Oracle Application Testing Suite and run the OATSxxx.exe to install OLT.

Maximum number of concurrent users that can connect to a SQL DB

I see various SQL DB plan S0, S1, S2 and P1, P2 and P3. Each one of them talk about DTU's but never talk about the max number of concurrent users. Where can I find that number and is it configurable by the end user?

It is the maximum connection that is most important. Best practice is not to have users holding on to their connection for long period of time. Maximum user connection in SQL is 32767, resource permitting. Not sure for Azure SQL. If you follow best
practice, you are not supposed to hit this limit cause other limits will be hit first.

Scalability in BlazeDS - What is the maximum number of concurrent users possible with BlazeDS?

Hi all,
is there a limit on the number of concurrent users that can connect via BLAZEDS? I see many places that it is only in 100s and not in 1000s.
is that true? Anybody has doen performance testing on that?
Thanks
Kiran

What is practical? Probably between 1 and 6 streams can be done with reasonable use of bandwidth. However, keep in mind that you will likely want to use the lowest quality setting for cameras so they are demanding the least amount of bandwidth.
Using the Connect 8 numbers, Low quality webcam video with the room at LAN settings should have an aprox average bandwidth consumption of 184 kbps. From there it is just simple math. 6 live streams at that setting will be 1.1 Mbps. Alternatively, at High quality webcam video and with the room at LAN, each stream will average aprox 501 kbps. 6 streams will average 3 Mbps.

# of Concurrent Users in an Application

Is there a way to determine the # of Concurrent Users in an application at specific points in time?
Thanks,
Mark

Hello Mark,
>> I was still left wondering about concurrent user usage of the application
Concurrent users in a Web environment/application is a bit tricky. One moment you are there, and in the other you closed your browser, and the application can’t really know that. So first you need to define what you consider to be an active user, and from that to compute concurrent users.
@Roel – I’ve just noticed your new title as Oracle ACE. Congratulations.

Arie.
Please remember to mark appropriate posts as correct/helpful. For the long run, it will benefit us all.

Number of concurrent users

how can I find the number of concurrent users in oracle 10g;
thank you

You mean ACTIVE users ??
Use following script :
active.sql
set pagesize 120
set linesize 150
select username, count(*) from v$session where status = 'ACTIVE'
group by username;
column spid format a5
column sid format 9999
column serial# format 999999
column username format A9
column schemaname format A8
column osuser format a20
column machine format a15
column logondate format a15
column terminal format a10
column status format a10
column module format a25
select a.sid, a.serial#, b.spid,
--a.process,
a.username,
to_char(a.logon_time,'DD-MM HH24:MI:SS') LogonDate, a.osuser, a.machine, a.status, a.module
from v$session a, v$process b where a.paddr = b.addr
and a.status = 'ACTIVE' and a.username is not null
order by 9;
--order by b.spid;

How can I know the number of concurrent users

Dears,
We have a sizing document from one of our vendors which is asking for the "Peak number of concurrent users in E-mail".
How can we estimate that? is it something like 5% of Total # of Users?

Hi,
If your field symbol has been defined as an internal table :
Use std describe as
Data: l type i.
describe <fs> lines l.
'l' will contain the number of lines as needed.
FYI
The size of this storage area in a field symbols depends on the number of table lines which is not fixed, but determined dynamically at runtime.

Amit

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 to find out number of concurrent users connectd to a site?

I would like to find out the number of concurrent users on my site. What is the best way to do it?
This is how I implement it currently:
I have a HashSet object in the session. whenever a user visits the page, i added the user's sessionID to the HashSet. But when a user leaves my page, it won't inform my jsp pages. The only thing I can do now is whenever I add a new sessionID, I loop through the HashSet and check to see which sessionID is invalid or inactive, then remove the it. Does a user session becomes invalid immediately when the user leaves the page, or it has to wait till it times out?
Are there any other more efficient ways of doing it?

Look at HttpSessionBindingListener. That will let you do what you want to, correctly.
User session will time not. If it were to become invalid immediately, it won't be called a "session" would it?

Where to find number of concurrent users in 10g OEM

I have recelntly installed an instance in oracle 10g release2 rdbms.Is this possible to find the number of concurrent users in OEM.If yes please show me the steps.

The number of concurrent users can be limited by the SESSION initialization parameter.
But it can also be limited by insufficient or misused resources. It is possible to set the system to permit 30,000 concurrent users (per your post in the Installattion forum) and go into heavy swapping or paging, causing the system to not accept the required number of users.
A lot depends on the real load characteristics you expect - you may want to consider shared server or RAC configuration for certain load types.
My instinct is to have very careful planning sessions, with several experienced Oracle DBAs and developers, around the instance configuration.

A dynamic Team Planner View to concurrent users

Hello, I currently have MS Project Professional 2010. Our business is looking into possibly upgrading our system but we need the team planner view in whatever we choose. We currently have hundreds of projects and thousands of tasks linked to resource pool.
The team planner view is the easiest and fastest view for the business to identify what each person is doing on a particular day, who is helping them, who is working on their project, who is on vacation, etc. Issues we're having right now include:
1) Project Professional freezes when multiple users try to access the team planner view at the same time. Even after downloading the hotfix package.
2) We tried uploading some work to Sharepoint but Sharepoint doesn't like tasks with start-to-start predecessors or lag times which greater than 50% of our tasks have.
3) The printable team planner view prints out hundreds of blank pages between sets of dates. I'm assuming they are "unassigned tasks" and there is no method of removing them. Resource names don't carry over to the second set of dates.
Is team planner view available in Project Server or the PWA? We're trying to find a way to get this view to everyone. Allow multiple concurrent users to view it at the same time. And to have their view change simultaneously as I change it without having
to upload or print a new team planner view every time I change something.
Thanks for the help.

Thanks for the reply Andrew. We explored using the Resource Assignment View but it had its own set of issues like:
1) I can assign up to 40 tasks a week to one person, this creates quite a list for each person as the Resource Assignment View lists the tasks in the column under the person's name. A filtered list of one week still creates a long list, 40-50 pages long,
for 30-40 resources.
2) Our resources had a hard time finding who was helping them on certain tasks because of this gigantic list. Again, they are unable to access MS Project without freezing the document so they can't open the task and find out who's helping. Therefore, we
like the condensed Team Planner view.
I will explore the SSRS report option but from a little light reading, it appears as though this report doesn't automatically update every time I make a change to the schedule. Therefore, I need to manually create a new report everytime I make
a change to the schedule?
Thanks Again,
Travis
