View 3 Replies View RelatedHi,
I have an application with a DAL that has an interface with SQL Server.
The application has 400 users that open the web forms.
My question is:
Is there a limit of the parallel connections that can be opened? Or the IIS is managing all the access to the DB? Should I worry about the performance Or it's normal behaviour for ASP.NET applications?
Thanks
Our development team wanted to create a database user for each application user in the application and use these for granular data access control, which at first, sounded like a good idea but our initial testing ran into some interesting results.
Our target user base was about 15 million users with an estimated 1% concurrency rate, and finding no MS documentation on an upper limit to the number of users a database can have we began some load testing to see how the database performed. In the hundreds of thousands of users range our test database had a hard time performing well under light loads (even without any concurrent connections).
When we purged the users and reverted back to just a handful of service accounts, performance went back to "normal" under the same loads. I began to wonder if this is a situation where throwing more hardware at the problem would overcome the issue or if there is a practical upper limit to the number of users a single database can handle well.
(There were of course other cons to this arrangement and I certainly was never going to expand the users tree in the object explorer for a database like this, but we thought it a solution worth investigating.)
What is the largest number of users any of you have had in a single database?
Hi all,
When I detach a SQL Server database, I see the following information:
Connections using this database: 5
Where are the connections from ? How can I check ?
Please help me !
Thanks
If I deploy a database to the web using sql express 05 is there a limit to the number of connections that can be made on it? I have read posts stating that but cant find any documentation from MSFT that supports that idea. I just know that it has a limit of a db size to 4 gigs.
Thanks!
Hi,
I read that there's a "tecnical" limit of 32767 concurrent connections for SQL 2005 Express, and that SQL 2005 Express uses only 1GB of memory. So, what's the number of practical concurrent connections SQL 2005 Express can handle? Is it 200 ,300, 0r 400...? How much memory is consumed by every connection?
Thanks in Advance.
Hi All
How to check number of active connections ?
I know two ways of doing it ..
1. run sp_who2
2. in Current Activity in Enterprise Manager ..
If what ever number I am seeing is the Active Number of Connections ..then
I am facing a problem here ..
In My serevr I have 75 Users licenses are configured for Per server option ..
Through a Java aplication when Developer tried to capture any SQL server Connection it says following error ..
Details :
[MERANT][SQLServer JDBC Driver][SQLServer]Login failed. The maximum simultaneous user count of 75 licenses for this 'Standard Edition' server has been exceeded. Additional licenses should be obtained and installed or you should upgrade to a full version.
If I see from Sp_who2 and Current Activity , I can see only 37 Connections ...?
Why is so .. If I am having 75 configured and 37 live in sp_who2 ..why I am getting that error message ?
Is there other way to see Actual Number of Connections made to server ?

Hi,
could somebody please let me know what is the maximum number of simultaneous users/connection per single SQL Server 7.0 box? Licenses are not the issue here, rather the number of physical connections supported before another server needs to be purchased.
Another variation of this question would be what's the highest number of databases that 7can be created on SQL 7.0 server and what is the highest number of physical connections supported per database? Again, licenses are not the issue. Thanks a lot in advance.
We have been running SQL Server 7 for the past 6 months, with no problems at all. All of a sudden, we have received the error message 17050, that the maximum limit for connections has been reached. We cannot now start Enterprise Manager or do anything. We have tried fiddling with licencing in control panel but to no avail. Does anyone have any idea why this has suddenly happened? Any tips would be great!
Cheers.
How does one enable sql connections limits for user connections per new and existing databases? how to do it on whole server per database but not set a limit per user.Looks like this must be run on each databases but what if you have 100s of databases:
USE AdventureWorks2012 ;
GO
EXEC sp_configure 'show advanced options', 1;
GO
RECONFIGURE ;
GO
EXEC sp_configure 'user connections', 325 ;
GO
RECONFIGURE;
GO

View 1 Replies View RelatedIn other SQL programs I have seen the use of Limit to tell it how many rows to return.
Is there an equivalent in MS-SQL that will let me do a quick Select clause and tell it how many rows to return.
In other words if I just wanted to see the first 10 rows what would I add to Select * from tableA
Thanks!
Hi,
Here's my problem.
I have an Area Chart, and I need to plot more than 300,000 records. Problem is RS cannot seem to handle this huge dataset. It would retrieve for 20mins, then after that it will just have an error "Internet Explorer cannot display the webpage". I am not encountering this if I just have a few records to plot. Please help

I am having a bit of a problem trying to limit a number of columns in a matrix appearing on a page.
At the moment, I have a dataset that lists the month and the mail packages that were sent during the month
The matrix works great HOWEVER, if there were more than 8 months in the matrix columns, it does not break and would make the page look like a huge landscape page.
I am trying to limit the number of columns appearing (this is the months column) on the matrix so that the pages stay in a potrait position. IE: every 8 columns appear on one page. Is there an option or an expression I could use in the Matrix ?
Thanks!

Is there a limit of how many rows a table can have in SQL compact Edition? I didn't find anything in the documentation, but I get regularly a funny error message "Expression evaluation caused an overflow. [ Name of function (if known) = ]" when I try to create record number 32768 (is equal to 2 to the power of 15).
Where is this limit documented ?

Hi There,
I would like to know what the recommended Number of Sql Mobile Databases Per Application?
I appreciate any response!
Thanks!
In my ASP page, when I select an option from the drop down list, it has to get the records from the database stored procedure. There are around 60,000 records to be fetched. It throws an exception when I select this option. I think the application times out due to the large number of records. Could some tell me how to limit the number of rows to be returned to avoid this problem. Thanks.

Is there a performance limit on the number of indexes per table / database ? With Filtered indexes there appear to be many more opportunities for more finely defined, and therefore smaller indexes resulting in many more indexes on a single table.
