How many users from an application can connect to a SQL server at a time?

HI,
I need to know , How many users from an application can connect to a SQL server at a time? Do we have any settings for this in SQL server for limiting the users?

This is a difficult question, since it is both technical and legal.
The absolute maximum number of connections is around 32700, but unless your server is very beefy, it will choke long before that. A connection is not a user - an application can have many connections for the same user. Depending on your license
model, you may be legally limited to a certain number of users, but this number is not enforced technially.

Best practise for creating an application that connects to a SQL Server database

I have created an application that connects to a SQL Server database and views information using a datagrid and performs several updates when a button
is selected.
I have created a SQLcontrol.vb using the following code:
Imports System.Data.Sql
Imports System.Data.SqlClient
Public Class SQlControl
'connection 1
    Public SQLCon As New SqlConnection With {.ConnectionString

A code for one of my button which views displays data grid contains the following code:

            SQL.runquery("select

I am fairly new to vb.net and have read a few books and followed a few tutorials on youtube, what I would like to know is, are there any disadvantages
to the way I have connected to a SQL database using the SQLControl.vb. A lot of the vb books include data adapter and dataset within the form, I'm not sure if I'm following best practice by have the connection details outside of the form.
My other question is, I have created two connections in the SQLControl and call these connections within the same form using the same data adapter
and dataset. It all works fine but I just wanted to know of any potential issues?
Public SQLCon As New SqlConnection With {.ConnectionString
= "Data Source=;Initial Catalog=;Integrated Security=True"}
'connection 2
    Public SQLCon1 As New SqlConnection With {.ConnectionString
= "Data Source;Initial Catalog=;Integrated Security=True"}
Thanks

My other question is, I have created two connections in the SQLControl and call these connections within the same form using the same data adapter and dataset. It all works fine but
I just wanted to know of any potential issues
1) You are not using Sepration of concerns for a solution that is doing data access, like using a DAL.
http://en.wikipedia.org/wiki/Separation_of_concerns
2) You are directly issuing SQL commands at the UI, leading to sql injection attacks.
3) You are not using a UI design pattern, which leads you to tightly couple database activity to the UI.
http://www.codeproject.com/Articles/228214/Understanding-Basics-of-UI-Design-Pattern-MVC-MVP
@System243trd, parameters are important to prevent SQL injection attacks (people will insert SQL commands into the database if you do not perform basic checking of what you are passing to the database). If you write a stored procedure try to make
the variables the correct SQL server data type to avoid problems later of people trying to call it directly.  Darnold924 is right, I see no code to prevent against SQL injection attacks. In addition, during development in some instances LocalSQLDB
database system is used and during deployment you usually need to use the production SQL server database. Moreover, Linq-to-SQL is used on Windows Phone 8.1 and it is required for phone development later and so I highly recommend learning
it if you plan on developing windows phone applications.
@System243trd, If you want the code for the windows phone app I think it uses the MVVM model or that might be for universal apps or regular windows phone apps. I have been using the windows phone Silverlight pivot or panorama template (it might
be pieces of both). I've already submitted to the windows phone marketplace and it had to go through certification first. I plan on later making an article on it but I need to first fix one or two simple problems I have with it. Here's a link to
the source code if you later want to look at the source code (in vb.net):

CONNECT TRAINING how many users in one license can enroll?

Hi, I have a regular license of Adobe Connect Name Host 100 Participants, It's work excellent for meetings.
I want to know if I buy one license of CONNECT TRAINING it's going to work in my current license of Adobe Connect , how many students can enroll my training content? need to buy more licenses? I want to use for on demand and live training.
I not a big corporate company it's only myself, want to do something more professional with curriculum, enroll students.
Another Question is about Adobe Presenter is this plug in for power point include in the Connect Training or have to buy apart?
Another question how many disk space have in my meeting room, for recording and library?
thanks for your help.

Martin,
Purchasing Concurrent Learner licenses will add the Training module to your account, unless you are on a monthly account through adobe.com, where the training module is not available.
The licensing for the Training module is for concurrent access to training content. 1 license means that one person can access training at any given time. You can enroll 15,000 people (random number, pick whatever value you want) in your training, but those individuals have limited access to the training based on the concurrent user load. If you want a plain English description of the licensing for Connect, you can find it here: Setting the Record Straight on Adobe Connect Licensing | RealEyes Media
Presenter is a separate license and is not included with the Training module.
Connect doesn't limit disk space. If on a hosted account, I believe there is 5 GB to start but more is added as needed. If on a licensed deployment, you are only limited to the amount of disk space allocated to your Connect server.

Is there a limit to how many USB/Fire devices you can connect?

I don't like the idea of having limited USB/Firewire inputs as I plan on having a ...
1). USB audio interface for Logic Express
2). USB connector for both an HD camcorder and a Nikon camera (although I most likely will switch between the two)
3). digitizing tablet
4). at least two external Firewire backup drives
5). scanner
6). printer (although that's connected to my Base Station)
Will I "overload" or cause problem with my computer?
Thanks!

Kind of even smells like diapers....
I picked up one of these Belkin MyEssentials 7 ports at Staple's, it has 4 ports on the back, 2 on top and 1 in the front.

My next choice probable would have been the following Cables to Go 7 port.

Can't connect to remote SQL Server 2014 Standard with VS 2012

Hi all,
I am trying to create a development environment using SQL Server 2014 (not Express). The SQL server instance is on a Windows 8.1 Pro machine in a non-domain environment. I have Visual Studio 2012 installed on the same machine which can connect
to the SQL server instance without problems. I have another machine with VS 2012 that cannot connect. SQL server is configured for mixed authentication. The SSDT on the remote machine can see the SQL server networked instance, but will not
connect with SQL authentication.
I have rounded up all the usual suspects;
- The SQL server service is running
- Remote connections are enabled on SQL server and the relevant firewall ports are open.
- TCP/IP and named pipes are enabled
- Remote connections are enabled in Management Studio
- SQL Server Browser service in enabled and running
What am I missing? I have been out of developer mode for a few years and all of the tools have changed, but I seem to be missing something obvious.
Many thanks in advance,
Tim

Hello,
Have you configured the Windows Firewall on the Visual Studio computer too? Is there any other security software on those
2 computers?
Can you ping between both computers by computer name? If not, try connecting using the IP address. For example:
10.0.0.10,1433
1433 is the default SQL Server port number.
Hope this helps.

Connect to Microsoft SQL server 2012

HI,
Currently My OSB connects to MS SQL server to get some data and then construct the request to submit to another web service. But recently the SQL server that I connect to has upgraded(previously was MS SQL 2005) to MS SQL to 2012. There are certain properties that needs to be changed in the connection property(for example : ApplicationIntent=ReadOnly) and I am not sure where to change this connection property. I am using sqljdbc4.jar for connectivity. Please advice. This is a bit urgent and appreciate if someone can help me out ASAP.
After the upgrade I am not able to connect to the SQL server DB as well. This is the error

You may need to configure the connection settings in the deployment descriptor (i.e. DbAdapter.rar#META-INF/weblogic-ra.xml) and restart the server. This exception is considered not retriable, likely due to a modelling mistake.

Hi All,
I really appreciate your valuable inputs. My hair about to fall because of this problem
L
Tom, thanks, I have gone through that article weeks ago, but no luck
J
The Summary:
I have made a work around to resolve my problem. I have created a new virtual server on the second physical DELL server (with SQL Express 2012).
The problem seems to be a network issue on the hyper-V virtual switch!!
More details:
As described previously, VS connects to SQL service within the same Hyper-V only, although all configuration are right. From any PC within my domain, I can connect to the SQL server on the first Hyper-V service using the ODBC or the connection string file
(.UDL), BUT not through the “visual studio express 2012 web” !!!!!!!!!
Now, I can connect from any PC (using visual studio express 2012 web) to any SQL server Express 2012 on the second Hyper-V .
I have made 4 virtual service on the first hyperV and 4 on the second HyperV. All with the same result:
VS on PC’s can connect normally to any SQL server on the second HyperV
VS on PC’s can NOT connect to any SQL server on the first HyperV
VS on virtual servers on first HyperV can connect normally to any SQL server on the same physical machine/Same hyperV .
VS on virtual servers on first HyperV can connect normally to any SQL server on the second physical machine/Second hyperV .
VS on virtual servers on the second HyperV can connect to any SQL server on PC’s or on the second HyperV/Same physical machine.
VS on virtual servers on the second HyperV can NOT connect SQL servers on the first HyperV
Long story that last more than one month

How many users for remote connection can I create, from support SAP

Dear all
I have a doubt with how many users can be created in my system ERP 6.0 for the remote connection, for the error product messages on the marketplace SAP,without this counts as user license.
I have not found any notes or documents from SAP to explain this.
I appreciate your help.
Best Regards,
Erika

Ok...I will reply to myself. I can use more than 10 simultaneous connection, using vnc.

How many users can connect to a shared drive on a non-server workstation?

How many users can connect to a shared drive on a non-server workstation? We're waiting for our server to arrive and in the interum we're using a Pegasus 2 R6 attached to an iMac running Mavericks as our fileserver. It's been sketchy, the connection to the server being dropped once in a while or the inability to mount the drive after a week of success. The Pegasus we're using now will be attached to a server once it arrives. For now I need to figure what's coausing trouble before I commit to this being our main storage as planned. The data is backed up every night so I'm not worried, its the usability issues. 5-7 people are mounting this drive and opening/saving at the same time. Is there a limit to Maverick's fileserving ability that may be causing this? Understandable if so.

The file server in the client version of OS X has a default limit of 10 simultaneous connections. That limit can be raised by installing OS X Server, or lowered by setting a hidden preference. Assuming you've done neither, you may be able to solve the problem temporarily by stopping and restarting file sharing in the Sharing preference pane, or permanently by setting another hidden preference on the server to break idle connections quickly.
defaults write /Library/Preferences/com.apple.AppleFileServer idleDisconnectOnOff -bool YES
Stop and restart file sharing. To reverse the change, run this command in the same way:
defaults write /Library/Preferences/com.apple.AppleFileServer idleDisconnectOnOff -bool NO
Credit for this solution to ASC member suter:
this file server will not allow any additional users to log on

How we Can find out How many Users Logon into the Portal those users Names.

Hi Friends

Hello Vijay,
If you are at all interested in a 3rd party application to make your life a bit easier getting stats on your users, you could check out Click Stream by Sweetlets.
Click Stream uses the Usermanagement (UME) API to get more information about the user, groups, roles, LDAP attributes etc. and offers you the ability to filter this information in nearly any report at the click of a button.
Click Stream also uses the PCD API to get information about the pages your users are visiting too.
In the very near future Click Stream will also have iView recording to monitor iViews, telling which iViews have been clicked, etc.
Here are some reviews on the SAP EcoHub from people who have used it: http://ecohub.sdn.sap.com/irj/ecohub/solutions/clickstream
Please just let me know if you have any question or if you are open to test drive Click Stream. We will certainly help as best as we can.
Good luck.

How to find out how many users are connected to Exchange 2013 servers in "Online" mode? This is coz, online mode causing server performance issues in our environment

All, Any script or method to find out how many users are connected to exchange servers in online mode?
Manju Gowda

Hi
You have to get the "RPC Client Access" log file in your CAS server. There you can see a column called "client-mode" and it has two modes such
as "classic" and "cached". From there you can get the two different client assess modes and their corresponding users.
probably take this file openup on excel and filter to see the two modes

Ldap - how to check how many users are connected?

Hi Guys,
Please help me.
We have iPlanet installed using LDAP. I want to check in ldap console that how many users are connected currently and monitor that.
please tell me how can i do it
thanks

Hi Noor,
Thank you for posting in Windows Server Forum.
From your description I can understand that you want the user name with app they have in their session.
You can achieve with below command.
Query process User name
Displays information about processes running on a terminal server. You can use this command to find out which programs a specific user is running, and also which users are running a specific program.
More information:

Hope it helps!

How many users can 1 Xserve support?

I have one Xserve (10.5.2, 2x3GHz, 5GB RAM, 1.34TB RAID 5) that I want to support the following services for my SMB:
DNS, DHCP
AFP, NFS, SMB
Open Directory
Print
Software Update
I also want to have mobile sync'd network home folders, but only for ~/Documents and iCals and Address Books (I don't want everyone's MP3s or family photos).
I occasionally will use NetBoot/NetInstall, but only 1-2 users at once.
I am getting ready to migrate my company to OpenDirectory and 10.5.2 for all users and was hoping someone here might be able to tell me how many users I can reasonably support with one Xserve.
Also, is it a bad idea to have everyone using "mobile" accounts? It seems like it would be less strain on the server to have the occasional sync from users than everyone reading & writing all the time. Also, if anything happened, there would be a local copy and a remote copy of any files.
Thanks.

Rosemarie,
BeehiveOnline currently supports 95,000 users and we have groups on the system as large as 10,000, that is probably about as big as we want to go - remember collaborating with 10,000 users is not an effective way of working - maybe a more open way of delivering content may be more appropriate. Given that the only issues we have with very large groups is the time it takes to run and the email traffic it generates as the large group are processed.
So it is possible to host 10,000 in a group but we need to be warned in advance and work with you to minimise the impact as the group is set up.

How to see how many users are working on a Dynpro application?

Hello,
Is it possible to see somwhere at the portal or on the WAS how many users are currently working with my Web Dynpro application?

Hi Roy,
I know it isn' exactly what you want but if you got to:-
System Administration->Support->Web Dynpro Test Tools->User Management
you can at least see the users currently running Web Dynpro applications (I think!)
At least its a start!
Cheers,
Gareth.
