Concurrent User in oracle

Hi friends,
I had already purchase oracle 30 users license and want to use in the platform where more than 100 work stations accessing the server. Is it neccessary to buy 100 user license to access the database at the same time, OR everybody can hook on to database only 30 users at a instant can play with database.
Pls. clearify me with your practical idea.!!

If you can get it to work, the Designer Web Assistant should provide unlimited user, read-only access via a web-browser. That was one of our reasons for installing it. However, I cannot determine when the 6i version will be available, and it has not executed successfully yet.

Max Concurrent Users for Oracle 8i

I am trying to find out information (white paper) that states how many concurrent users 8i can handle. Does anyone know of somewhere to get this data?
Thanks in advance,

Can you post the entire dump from the console?
Where are you getting the term "Concurrent Users"? Concurrent Users is a term Oracle used to use (or maybe still do) when licensing products. I'm just interested where you are seeing this from.

No of concurrent users on oracle 10g

Hi Guru's,
We have a requirement where 200 + user will have a connection to our database at a point of time. We have windows 2008 + oracle 11.1 in our envirnment.
Now my question is ..What steps do i need to take that all connection are taken care by databse and no connection gets failure message.I tried this by 100 connnection but after 100 it is giving error .(listener error..)
Please let me know in case any more detail is required from my side.
Thanks
Vivek

As you never posted what listener error you got, my guess is you hit ora-12500, which usually means the maximum number of threads for the Oracle process is reached.
You can configure the maximum number of threads in Windows, but I do not know from the top of my head how, so I suggest you visit http://technet.microsoft.com

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;

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.

# 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.

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.

No of maximun users in oracle 10g express edition

what is the maximum number of concurrent users (session) in oracle 10g express edition.
coz right now, we have one server with oracle 10g express edition, and a front end application of asp.net (.net 1.1)

The only limit that Oracle places on the number of concurrent users on an XE database is through the limit of 1GB of RAM. You can have as many concurrent sessions as you can open in 1GB of RAM.

What are the AM Tuning parameters need to be set for 500 concurrent users

Hi All,
We are using JDEVADF_11.1.1.5.0.
What are the exact AM parameters(Pooling and Scalability tab) to be set when we planned for 500+ concurrent users?
Along with this do we need to set any parameters at weblogic server level, if any please give inputs.
Any input's would be appreciated.
Thanks in advance.
Regards,
Dinesh

We can?t give you exact numbers as there are many factors influencing the performance. In hte end you have to make a load test to find the right set of parameters. A good starting point is Andrejus's blog Andrejus Baranovskis's Blog: Stress Testing Oracle ADF BC Applications - Internal Connections and Andrejus Baranovskis's Blog: Stress Testing Oracle ADF BC Applications - Do Connection Pooling and TXN Disconnect Level

Number of users in Oracle

Hi
I run a data mart application on Win2k3 dual processor Dell Server on Oracle 10g R1. 8 GB Physical RAM 1.7 GB for the SGA and 1.5 GB for the PGA. How many users can be connected concurrently to do a performance testing ? Roughly an user would have around 2 MB of data fetched for his query.
Will it help to move to a Sun Solaris 64 bit machine with 8 GB RAM for a larger SGA and PGA to increase the number of concurrent users ? What parameter affects the number of concurrent users ?
Thanks
Dev.

No one is going to be able to tell you how many users your particular system can support. There is exactly one way to determine this, by doing a load test. Schema design, the presence of appropriate materialized views, the nature of the queries, data volumes, initialization parameters, system bottlenecks, timing requirements etc. will all come into play and none of us knows your system as well as you do. You would have to set up an appropriate test that simulated the type of users you expect on the type of data volume you expect to see.

How to find out how many concurrent users using web application?

Hi all,
I have a web application deployed using 9iAS. I am trying to find out how to find out how many concurrent users are using this application at any one time. According to Oracle there is no way to see this information using the enterprise manager interface.
Does anybody out there know how I can find out this information in real time? Failing that, are there any good analysis tools out there that display usage to the minute (all the tools I have found show usage by hour which is not sufficent for my needs).
Any help would be much appreciated,
Caroline

I know I haven't heard of any software to do this, but this also sounds like a really hard problem to try and really analyze well.
The trick is, you might "infer" how long a user is using an application based on when cookies are set and when they're set to expire. If that's a long time, though, that could count far more "concurrent" users than are actually there. A user could simply close the application at any time and stop using the application; you can't really detect that because the server isn't "told" when the user closes their browser or goes somewhere else.
A good perl script might be able to read the Apache access log and tell you how many unique IPs asked for a given directory in which various applications are stored in any 5 minute span of time... that could be something like an indicator of "concurrent" users.
If you don't know Perl, I'd suggest getting the O'Reilly & Associates book on Perl and learning it, because the more I think about this, the more this sounds like a textbook example for applying a Perl script.

Max number of concurrent users?

I'm in the process of creating a web site with Cold Fusion and
Oracle. One concern involves the lack of web hosting services
that run Oracle on their servers. So, to get around this
problem, I was considering replicating an Oracle lite database
and putting it on an ISP's server. My thinking is that there
would be little need of DBA functions and I can run it on any
server I choose. But ....
1. Would Oracle 8i lite support a lot of concurrent users?
2. What other factors would I have to consider if I set it up
as a distributed DB ?
Any help on these thoughts would be greatly appreciated.

Simple question: No of concurrent users

How many concurrent web based users can oracle 8i/9i personal and standard edition support?

I believe that all depends on the hardware resources you have available. I don't know any 'real' limits on the number of concurrent users. If you are asking from a licensing perspective, that all depends on the kind of license you purchase

Running Apps 11i on Linux with 200 concurrent users

Hi,
Is there anybody out there running a large apps 11i installation (with the
database and middle tier) on Linux ?
We are currently running 11.5.9 Apps with a 9.2 database on Sun kit but I'd
like to investigate Linux/Intel as we are planning to replace our hardware.
We have about 200 concurrent users, with a total of 1800 registered users, using
Financials, i-Procurement and HR.
Thanks
Tony Vallis

Having worked extensively on Linux, its true that is is limitied in 32 bit mode to addressing a few GB of memory for each application (It is at least better than windows with its 2/3GB limit), although you can play around with it and memory windows to get more out of it for the database tier.
We have used 1 * 6650 with 8GB RAM running AS 2.1 DB Tier
and 2 * 2650 with 8 GB RAM ruuning AS 2.1 Apps Tier with conc mgrs too.
This was with 11.5.10 and it comfortabley supported 200 users. The servers were 2.8GHz Dual core Xeons. Redhat 3 or 4 would have been better becuase of a file cache issue on the database tier.
Also rememeber to consider Oracle licensing, A faster CPU might cost alot more but when oracle licenses are based on core/cpus then you may save alot more by having the highest power cpus u can (MHz rating not ness cores). Sun T2000 servers are quite nifty too if you want to stay with traditional unix kit but not want the price tag.
When workign at internally in Oracle We quoted one client a 3 * 4 CPU 6650 with 8GB in RAC config with 12 * 2 CPU 2650 with 4GB to support 5000 concurrent users. I wasnt convinced this would work at the time but the client had massively over estimated the number of users they would actually have so all was fine.
If I was doing this now I would go for a single 64bit DB tier with 4 CPUs and lots of memory, I would have lots of small8gb mid tiers 2850's, with a hard ware load balancer in front and a dedicated GB backend network. I would ony go for RAC if I needed the resiliance or had a large number of users e.g. 1000+
All in my opinion and I am in no way suggesting this as a solution for any other customers. Always perform a hardware siazing exercise in conjunction with your hardware vendor (remembering they always want you to buy more hadrware than u need).
