"Maximum Number Of Connections Already Opened" Error Message?
Jan 4, 2011
I developed a web site using Sybase PowerBuilder V12.0 Classic and the output is deployed and converted to ASP.Net (ASPX) web pages.The Database connection is configured and used properly as the data is displayed in the web application using DataWindow Objects and is a direct connection with sybase Database Server using Dsedit Tool and No ODBC is used.I edited The Sybase Databse configurations related to remote servers and connections to be more than the default value which was 25 although the real number of users will not exceed that in the same time.Recently I received an error message when some users connected to the web site and after making valid logins:-The Error Message is:-Maximum number of connections already opened ct_connect(): user api layer: external error: The maximum number of connections have already been opened.
I am confused about the causes of that error as I think I had made all configurations needed and I checked evey option and setting related to the Number of Connections in The Sybase Database server, The Application Deployment Settings in Sybase PowerBuilder V12.0 Classic, and The IIS Settings.I use Windows Server 2003 and the IIS version is 6.0 in the Web Server.

is there a way to redirect a user when there are n people/sessions on a site. I have a requirement to redirect to a 'sorry we are busy, please try later' page if there are too many people currently engaging the site (this is to stop flooding a live business service that is behind the webpages). The ideal is that only new users (users not already logged in) are shown this page. I was going to just count concurrent logins but wondered if there was a better way to count current activity rather than login status being that most users might stay logged in for a while.

We're trying to write an error tracking solution for our sites and ran into something interesting. Sometimes the error exception includes the actual file and line number that the error occurred on and other times it doesn't. Is there a setting somewhere that we need to change to enable the file and line number to be returned? The two situations are each on a different server. Do we need to change something on the server?
Examples, with error file and line number:
System.IndexOutOfRangeException: Intro at System.Data.ProviderBase.FieldNameLookup.GetOrdinal(String fieldName) at System.Data.SqlClient.SqlDataReader.GetOrdinal(String name) at System.Data.SqlClient.SqlDataReader.get_Item(String name) at AccountUser.get_PracticeInfo(String sUserName) in C:xxxxxxxxxxxxeta.xxxxxxx.comAccountUser.vb:line 106
Without line number:
System.NullReferenceException: Object reference not set to an instance of an object. at Dealers_Toolbox_UserEdit.LoadRoles()

I am trying to determine if I have a database connection leak. So I need to see the number of open connections. I have some simple test code that creates a leak:
protected void Page_Load(object sender, EventArgs e)
{
for(int i = 0; i < 100; i++)
{
SqlConnection sql = new SqlConnection(@"Data Source=.SQLExpress;UID=sa;PWD=fjg^%kls;Initial Catalog=ABC");
sql.Open();
}
}
Note there is no .Close and this does infact crash after being run 3 times in quick succession.
In order to measure the leak I am running the Performance monitor and measuring SQLServer: General Statistics/User Connections:
However, these seem to be zero when I run my code:
What should I change to actually see the connections?
ANSWER
I have approved an answer below. Even though it doesn't use the performance tools, its good enough for my use. Bottom line is I wanted to see how many connections remain open after opening a web page and this did the trick.

I've got a sql table, that just keeps getting more and more columns added. I optimize the db as much as possible, but am curious about how many fields a table can have, and if there is a way to check if I'm getting too much data per row?

My ASP.NET MVC 2.0 web application does not maintain any session state and My production machine has n (>1) core, .NET 4.0, IIS 7.5 Integrated mode.For increased performance, I am curious if I should increase the max concurrent threads in thread pool to 12*n or should I keep the max concurrent threads as 12 but assign n worker process (w3wp.exe) to my application pool. What are the pros and cons of one over another?

I have an ambitious requirement for an asp.net 2.0 web page that contains a table (gridview), and each row in the grid contains 6 select (dropdown) controls for data entry. The number of rows that will be displayed is dependent upon the user's search parameters, which are specified in another area of the page. Unfortunately, with the default (and even basic) search parameters specified, the grid could contain several hundred rows. I've noticed that the browser, in this case IE8, starts behaving rather erratically once I reach a large number of rows -- no documented evidence for the number of rows where this begins to be a problem. For example, trying to view the source of the page results in a message from IE stating that there was a problem with the page that forced the browser to reload it, and I never get the source. Obviously the page loads and renders rather slowly also.
I know that my solution is probably going to involve paging the gridview such that it only displays 20 or so rows per page, and I'll have to write code to handle the saving of changes in the dropdown values when the user changes pages. I can probably turn off viewstate on the gridview also. However, the question I really want to pose is this -- has anyone seen a documented rule indicating the maximum number of input controls that an HTML browser form is supposed to be able to contain? I could not find anything on the Internet after doing a search, and I suspect the answer may be whatever the browser can handle based on the machine configuration it is running on. Any rules of thumb you use?

one of our programmers is having an issue with a asp.net app. i had him rebuild and recompile the app to the network share on the staging server and received the same error. i even deleted the files in this folder
(C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files). to make sure that the server was not the issue i installed it on another server and received the same error. i found a article on msdn that states that its a source code issue. Compiler Error Message: BC30041: Maximum number of errors has been exceeded. Source Error:

it's a multiline TextBox the MaxLength property does not work. At the moment I only see the option to use a CustomValidator with checking TextBox1.Text.Length on server side and perhaps in addition some Javascript client side validation.But isn't there a simpler way to do this, using the standard ASP.NET validators (RegularExpressionValidator, RangeValidator, CompareValidator, etc.)

I have a gridview, in which i placed checkbox as Itemtemplate. My need is to restrict the user from selecting more than 'N' number of selections.
Eg: Gridview contains 50 records, that means 50 check boxes.
Max permitted selections: 10.
After the 10th checkbox selection, user should be prompted that..
"No more selections.. blah blah... "
Should i go for looping through records.. or is there any better way..

I have a PDF document with a number of text fields, several of which have a maximum length - namely, a maximum number of allowable characters. Is there a way using iTextSharp to determine this setting? Here's the code I have so far:
Dim reader As New iTextSharp.text.pdf.PdfReader("Foobar.pdf")
Dim inputFields As IDictionary(Of String, iTextSharp.text.pdf.AcroFields.Item) = reader.AcroFields.Fields
For Each key As String In inputFields.Keys
Dim PDFFieldName As String = key
Dim MaxFieldLength As Integer = ???
...
Next
I need to set MaxFieldLength to the number of allowable characters for the current form field being iterated over.

I have developed an application using Winforms that connects to the Database using WCF services. All the services are working fine except those that return huge amount of data from the database. I did increase the size of the maxReceivedMessageSize and maxBufferPoolSize to 9223372036854775807 in the Config file of the client which I believe is the largest but I still get the error message "The maximum message size quota for incoming messages (65536) has been exceeded". I am using visual studio 2010 with VB.Net programming language on the client side and C sharp on the server.
I also goggled but the nearest solution I got was to increase the maxReceivedMessageSize which I did but in vain. Below is the detail of the error: "The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.

I want to create a page on which the website's sponsors are displayed. The information about the sponsors is coming from the database via an ObjectDataSource, and I'm retrieving an Image (company logo), the name of the company, and a url to the company's website. Each Image (logo) is of the same height, but of varying width. I want each Item to be formatted so that the Image is on top, and underneath is a centered hyperlink with the name of the company.
This all seems pretty straightforward ... now for my problem: I want to display as many of these on the page as possible. Essentially, start off horizontally and fit as many as possible on each row. A DataList or Repeater with RepeatDirection=Horizontal doesn't quite do what I want as I don't want to have a fixed number of columns.
Is there an easy way to achieve this, or do I have to manually add up the width of each item on an ItemDataBound event, and then somehow move to the next row when the maximum width is reached? In addition I have to deal with the fact that the width of my Item is the maximum of the Image width and the text underneath.

Are there any tricks for getting rid of this error? The long query is required for this program. Will I need to build a new table before the query runs?

By default in login template, in case user key in the wrong user name or password, the literal message will show the default error message, "Your login attempt unsuccessful..."What i trying to do is, I have a function in my system to disapprove a member, after the member is disapproved, he/she will not allow to login anymore. When the user trying to login, the default literal msg will show out. Is there any way i can do it more specifically like if the user enter the wrong password only, the literal msg show: "Wrong password entered" insteaed of the default msg?
Same goes to the change password control, for any error msg it just show the long msg but does not tell user whats wrong with the entered valueim trying to do something like if the user enter the wrong password, the literal msg show the one i wan to show.
