Connection Pool Needed?

Apr 12, 2007

From what I understand, some database drivers provide automatic database pooling, in the sense that when an application closes a connection, it is not dropped until after a certain timeout. If the same, or another application, request a connection then the "pooled" one is returned.

What's the situation with C#, .NET Compact Edition and SQLce? Is it a performance hit to open and close a connection, or is some kind of automatic pooling in effect?

Thanks.

Isolation Level Of Connection In Connection Pool

Feb 16, 2007

client: ado.net 2.0 SqlClient, xp sp 2

server: sql server 2005, win 2k

I have a stored proc eg spProcA which does not start a transaction

If I call this proc from ado.net code without any transaction around it affecting the isolation level, the isolation level within the proc call is read committed, as expected

If I then call the same proc within a System.Transacstion.TransactionScope with a different isolation level eg Serializable, then i get the expected isolation level in the proc.

However, if i retry the proc without any transaction around it, the isolation level is now the same as the TransactionScope, (eg Serializable), and this persists until either the connection pool clears down (either because it becomes dormant or via an explicit ClearAllPools.

I can resolve this problem by setting the isolation level in every proc (or call to every proc), but i wondered if i am missing something more straight forward?

Connection From The Pool

Mar 14, 2007

I build an asp.net 2.0 (VS 2005) web application and put it on the server. The installed SQL server is SQL server 2003. I get this error message when i keep the application running for 10 or 15 mins. "Timeout expired. The timeout period elapsed prior obtaining a connection from the pool. This may have occure because all pooled connections were in use and max pool size was reached."
I made the server timeout unlimited but the error keeps coming up after some time of openning the application. The application session time out redirects the user to the login page and doesn't throw an error like the one i mentioned above.
Any idea. Thanks in advance.

SQL Server: Connection Pool Low...

Apr 7, 2005

Hi guys!
I have a dev server that has about 15-25 connections which is fine.
**
    Looking at performance counters: _global_
    under SqlClient: Current # connection pools
    under SqlClient: Current # pooled connections
    under SqlClient: Current # pooled and nonpooled connections
**

BUT when I look at staging and production I have only 4 or so...
WHAT'S GOING ON?!?! The querystring doesn't specify the max pool
size, pooling, nor timeout values. So I'm guessing it uses the
defaults. ( I also tried putting in max pool size, but it didn't
change anything! )

Does anyone know how I can increase the value? It is impacting the performance of the site considerably. Thank you!

Timeout When Obtaining A Connection From The Pool

Oct 6, 2006

Hi All,I'm having a bit of a problem with a c# program which creates and index file/table. The number of records I need to process is around 3500, the main loop. Each of thoes records I need to look at a 2 text fields and create an entry in an index table for each valid word found in thoes fields. I call a stored proc to save the key word. So this stored proc get called numerous time per record.What seems to be happening is proceese about 400 main rcords the errors out with the following error message: {"Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached." }Has anyone had a similar problem? if so any suggestions on how to fix, I've been looking at this problem and recoding for the last 4 days! I need some help! Using SQL Server 2000 & .net v1.1Thanks in advance Davej

Inconsistent Clearing Of Connection Pool

Jan 15, 2008

I'm opening a large number of connections to a SQL server 2005 database using a SQL object based on the System.Data.SqlClient library. When I log out of the application, I call the ClearSQLConnectionPool method of the SQL object and this should clear the pool of these connections. This has worked in the past, but lately I have noticed some odd and very annoying behaviour.Very often I log out of the application and few, if any of the connections disappear. Just this morning I opened the application, logged out and all but one of the connections disappeared. Then I opened it again, logged out and none of the connections had gone. If I open the application again all of the past connections are still there plus the new ones.I know it works, its just very inconsistent. The problem may be with IIS, SQL or with library; I just can't tell which.Any ideas?Many thanks

Timeout / Obtaining A Connection From The Pool - Please Help!

Jul 20, 2005

Dear GroupSorry for posting this here. I'm desperate for a solution to thisproblem and thought some of you might have come across it with .NETand SQL Server.Let's assume I've the following code:Private Sub Button4_Click(ByVal sender As System.Object, ByVal e AsSystem.EventArgs) Handles Button4.ClickDim sqlConnection As New System.Data.SqlClient.SqlConnectionsqlConnection.ConnectionString = "workstation id=THEINTREPIDFOX;packetsize=4096;user id=sa;data source=""(local)"";p" & _"ersist security info=False;initial catalog=TestDB"sqlConnection.Open()sqlConnection.Close()sqlConnection = NothingEnd SubWhen I click 100 times on the button the page finally times out with:Timeout expired. The timeout period elapsed prior to obtaining aconnection from the pool. This may have occurred because all pooledconnections were in use and max pool size was reached.Of course I could increase the max pool size but this isn't thesolution to this problem. I wonder what's wrong with my code?According to MSDN, if the connection is closed it's released back intothe pool. Also tried to dispose but nothing helps. It looks like thatit keeps connections and doesn't release them. I'm grateful for anyhints, ideas, suggestions on this problem as I'm very desperate tosolve this.Thanks very much for your time & efforts!Martin

SQL Server, Connection Pool And Connections Remaining.

Dec 19, 2003

Hi

I have seen the threads already in here about connections and SQL Server but I too am having a connection pool problem.

I am explicitly making a connection, creating a command object, executing a datareader then closing the command and then disposing the connection. The connection just prior to the dispose is definately closed.

However when I do an sp_who in SQL Server the connection is still listed. I have a connection timeout of 30 seconds, so I am considering reducing this to 5 seconds but dont wish to. So therefore when a process is called repeatedly instead of using an existing connection in the pool, it thinks that this connection is still active and therefore creates a new connection. Because all of this is in an ascx, I cant code for one connection to stay open for all 30 instances of the control.

This is a problem because I am creating controls at run time and using page.databind and at that point, I exceed the connection pool and therefore the site crashes out to the "SQL Server Timeout" error.

Anyone else seen this?

SQLServer 2005 - SP2 - Connection Pool Issues

Sep 5, 2007

Hi,

I have recently installed SP2 for SQLServer 2005 and started to have connection pool issues. I have tried to explicitly mention the pool settings in connection string and yet pooling doesn't seem to work. I have one more box with no service packs applied and is pooling is perfect!. Has any one experienced this??

Thank you,

Connection Pool To Access Sql Server For Multiple User?

Dec 12, 2007

HI,

I am using SqlServer2005 as data base for my web application. I am able to connect to the database through DBCP connection pool . Its working fine for 2 user. When ever 2 users do transaction, it works fine. But 3 users do the transaction, its trowning error.Even i increase the pool size the behavior is same.
error:
com.microsoft.sqlserver.jdbc.SQLServerException: Server failed to resume the transaction, desc: 3f00000002.

For a change I wrote a connection pool to access the DB. I am getting the same error. i.e. Its working fine for 2 user and throws error for more than 2 users.

Is there any setting to be made?

Same application is working fine for Oracle10g.

How To Explicitly Allocate An Sql Server Connection From The Connections Pool

Feb 21, 2008

Hello.

I have a db dal containing the following code:

SqlCommand cmd = new SqlCommand();

cmd.Connection = dbc;

cmd.CommandType = CommandType.StoredProcedure;

cmd.CommandText = "SOME STORED PROCEDURE";
.
.
.
declare some SqlParameters
.
.
.

dbc.Open();

cmd.ExecuteNonQuery();

dbc.Close();

This code, when concurrently running via several threads, yields the following exception:
"The connection was not closed. The connection's current state is open."

My questions are:
1. Why don't .Net allocate another connection from the pool (I try to only concurrently run 2 threads while there are 25 connections in the connection pool) ?
2. How can one explicitly allocate a connection?
3. How do you suggest to solve this problem without a mutex/monitor etc' on the 3 bold lines above and without BeginExequteNonQuery()?

Thank you !

Question About Connection Pool From The Servers Point Of View

Nov 2, 2007

I was wondering if someone could help explaining how the SQL Server handles all incoming connections, I and a friend started a discussion about using the connection pool in ADO.NET or not in a specific case.

Usually when creating like an ASP.NET Page it's recommended to use the connection pool, because it optimizes the performance, by using already created connection, so we don't have to recreate the connection all the time. I have always thought that the connection in the connection pool had an open connection on the server. So 5 connections in the connection pool, would be 5 open connections at the server. But after having the discussion with my friend I am not so sure anymore.

Say that I would create a client application (.NET using ADO.NET) that connects to the database and work with that data. If I then have 1.000 clients and each client have a connection pool with 5 connections in it (I think that the default numbers for the connection pool), then there would be like 5.000 open connections on the SQL Server, where most of the connections actually never do anything more than hanging around and waiting... And then the connectionpool is not 1 per client but 1 per connectionstring.

So if my client scenario would access data from 2 different databases, there would actually be 10.000 open connections at the SQL Server. So now I think that there must be a server connection pool or something to handle the connection from the clients. So that there would only be like 10-50 open connections at the server for the 1.000 Clients that was connected.

How is it? Is there 1 open connection in the server for every connection in the connection pool? If that's the case, it would be better for the SQL Server if I don't not use the connection pool in the client, but instead open the connection when we need it, and then close it, and taking that little performance hit every time, to help the performance on the SQL Server.

Best regards

Need Advise. Problem With Connection Pool. Function Returning SqlDataReader.

Sep 6, 2007

Halo all

I have a problem with "timeout expired. Thei timeout periode elapsed prior to obtaining a connection from the pool. This may have occured because all pooled connections were use and max pool size was reached"
Then i explore and found out that i did not close my SqlDataReader, SqlDataAdapter, SqlCommand or my connection.

But i have a function that return a  SqlDataReader.
Is this function will cause a connection problem?

Thanks in advance

        Public Function GetDataReader(ByVal strSQL As String, ByVal DBCon As DB.DBConnection) As SqlDataReader            Dim MyCommand As SqlCommand = New SqlCommand(strSQL, DBCon.GetConnection())
            If DBCon.GetConnection().State = ConnectionState.Closed Then                DBCon.GetConnection().Open()            End If

Facing Problem In Increasing Connection String Pool Size Sqlserver

Mar 4, 2005

Hi to all,

I am using a connection string like

data source=RemoteHostName;initial catalog=myDb;password=sa;user id=sa;
Max pool size = 200;

And now strange thing is happening ,, I am receiving error :

Timeout expired. The timeout period elapsed prior to obtaining a connection
from the pool. This may have occurred because all pooled connections were in
use and max pool size was reached

The SqlServer Activity Manager is telling that only 100 connections are pooled, and I guess that the Max pool size is 100, It is not being changed by my Connection string. As I am trying to change the default 100 pool size value to 200.

Huh , So stucked up , how to increase the Max pool size.. Is there any way .

I am getting worrried.

Any help ??

Thx and Regards

Timeout Expired. The Timeout Period Elapsed Prior To Obtaining A Connection From The Pool.

Feb 5, 2004

Ok bear with me here :). I have a server that is getting about 1000000 hits per day with about 10,000 unique vistors. For the past 2 months I have been revamping my code trying to deal with the increase in traffic. I have 2 boxes, one for the website, and one for the SQL. They are connected through a secure backlink so that I dont have to worry about encrypting the data. So the problem started when I updated the MDAC components a few weeks ago. I started getting these freaking timeout errors, they are up to about 1000 errors per hour. I have been monitoring the connection pooling using the system monitor for about a week and have noticed that I am not maxing out the pooling but I am still dropping connections. I went into the web.config and turned my max connections to 1000. Unfortunately this didn't even put a dent in the problem. It doesn't matter if I have 12 or 212 open connections it still drops them. I am at my wits end with trying to debug this problem. I am wondering if anyone else has had similiar problems recently. Also on a side note I have checked all my connections to make sure that I am closing them. Not only do I close my datareaders but I also set them to nothing. In addition to closing and reseting my datareaders I am also disposing and reseting my connection objects as well as closing them. Any help would be greatly appreciated.

Thanks,
Daniel Christoffersen

Connection Pool Leak In Production Machine (in Other Machine It Runs Well)

Nov 16, 2006

Hi to everyone,
I'm facing a problem that drives me crazy. I've a web application that has the following problem. When I test the application on my developement machine all runs fine, but when I put into production server there is a problem in connection pooling. Look at the following image, the blue line is the number of connection in the pool and the violet line is the number of connection reclaimed. From the image it is clear that connection are returned on the pool only in block, maybe when the garbage collection pass and reclaim the object. The strange thing is that on my developement machine all is good, and also I'm using Enterprise Library and the connection are managed internally.- Thanks to everyone for any help.

Help Needed In Establishing Connection

Apr 29, 2006

I recently migrated SQL Server 2005 which we use for our internet site and other internal applications, to it's own server. SQL used to be on the development PC. However now I am having security issues.

I keep getting an error message when I try to connect to the server from the development PC that the SQL server is not set up or does not allow remote connections. I have made sure that ASPNET is a user. I have also run aspnet_regsql to set up the internet users database.

What other security features do I need to check? I am more of a VB developer than a SQL admin so any help is appreciated.

FYI - This is a small network that does not run any form of Windows Server. I am using IIS 5.1. TCP/IP and Named Pipes is enabled.

Thanks

Advice Needed For Connection To DB2

Apr 20, 2006

I am writing a report in RS and my query is supposed to pull transactional records from a certain date (yesterday).

The table I am querying contains roughly 1.5 million records. This is on an AS400 dB2 system. Mostly I use ODBC with no problems, however this query ran for about two hours and was still running before I killed it.

I am thinking of using SSIS to copy the records into SQL. If I go this approach (which should be much faster), is there a way to just copy over differential records each day?

Or does anybody have any other suggestions? What is Linking a Server?

Thanks for the information. I am using SQL 2005

Needed: User, Login, Connection Advice.

Mar 12, 2005

HI,
I'm still on the steep side of the learning curve with ASP.NET. I've looked through a number of threads on this forum, and have gotten pieces of the answer, but need help getting past a roadblock.

I haven't been able to get a simple test application to connect to the Pubs database loaded on my system running MSDE. The only control in the application is a WebDataForm created by the Wizard. Everything works well (even the Preview Data form the Data menu loads and displays the correct data), except when the form is viewed in a browser. Click the load button and an error:Login failed for user 'NT AUTHORITYNETWORK SERVICE'.

Similar stories are common on this forum, and I tried to address the problem. I'm quite sure it's a autherization or authentication problem. I have Windows Server 2003 (with IIS 6.0), VS.NET 03 and MSDE as the SQL server on the same box. The MSDE server is using Windows Security mode. I Created a new user called ASPNET on the Windows Server. I added a login to the SQL Server 'WinServerNameASPNET' using windows auth. Still get the same login failed message.

Is there something I'm missing? Do I have to add a new user to IIS?

For the record, what users/settings do I need to have in Windows, SQL-Server and IIS, get past this login problem.

Thanks for answering this basic question - one more time.

Help Needed -- Dynamically Defining Files In Connection Manager

Nov 12, 2007

I am pretty new to SQL Server 2005 and SSIS. I am trying to dynamically load files into SQL Server 2005 using files/paths contained in tables. I have a key table in my SSIS package that defines which files should be processed, some default values that will be associated with each file (ie CompanyKey and PeriodKey) and the file path (see below for example):

CompanyKey

PeriodKey

ProcessFlag

FileName

2

61

FALSE

2005TB200501.xls

2

62

FALSE

2005TB200502.xls

2

63

FALSE

2005TB200503.xls

2

64

TRUE

2005TB200504.xls

2

65

TRUE

2005TB200505.xls

2

66

TRUE

2005TB200506.xls

2

67

TRUE

2005TB200507.xls

2

68

TRUE

2005TB200508.xls

2

69

TRUE

2005TB200509.xls

2

70

TRUE

2005TB200510.xls

2

71

TRUE

2005TB200511.xls

2

72

TRUE

2005TB200512.xls

The package I am developing is supposed to loop through this table checking for files with ProcessFlag = TRUE. For those files, it will load all of the records/columns (prefaced with the company and period keys) into a common table.

Do I have to manually create data sources for each file or is there a way to dynamically define the connection and process the connection?

Any assitance you could provide would be greatly appreciated!

Thanks.
Vik

Reporting Services :: Parameters Needed For Connection And Again At Report Run-time

May 5, 2015

In VS2008 SSRS, when creating a dataset, only the name of the stored procedure was required. When populating the dataset, VS prompted for the parameters, whether or not there were any. In VS2010, the name of the stored procedure is not enough if there are parameters.When creating a dataset in Visual Studio 2010 for databases and stored procedures in SQL 2012, I must provide (what should be) run-time parameters to obtain a field list and then to preview the report.

So the embedded dataset looks like this (wherein the only parameter is a password): exec dbo.spu_procedure1 @PW='999'.This works well and as expected during report design and development. But 999 must be provided at run-time by the requester, and not in the dataset definition. If I remove the parameter in the dataset's exec string before deploying the report, the field list is cleared and the report is unusable. So I cannot overcome what seems a contradiction: necessary to obtain a field list, but "yet-to-be-provided" when the user selects the report.

By keeping @PW='999' in the dataset specification, the user cannot override the parameter and automatically has a password to view the report.

TestProd Databases On Same Server; Same SSIS Algorithm But Different Connection Strings Needed

Jul 27, 2006

We have an SSIS package that will be used for both our Test and Prod imports on the same server. The SSIS imports are identical expect that Test needs all connections pointing to the Test database while Prod need its connections pointing to the Prod database.

How can I change the connections, based on Test or Prod, used inside a single SSIS package? (I don't want to create two tweaked packages on the same server. If I find a bug in one of them, I have to correct it twice.)

TIA,

The Use Of Pool Or Pooling?

Jul 13, 2006

1) What is the use of pooling actually?
I have an online application using SQL server, where I can check the connection pool from, SQL Server Enterprise Manager->Microsoft SQL Server->SQL Server Group->LOCAL->Management->Current Activity->Process Info.
2) In the connection pool, when I log into my system, a connection is made as I run query using stored procedure thus making the process available in the connection pool. Now when I am done and log out of the system, does the process suppose to stay there or not (the connection closed) and making it disappear from the pool?
I read from some forum that pooling is a good thing as it make accesing data faster.

SQL Pool Connections

Aug 22, 2006

HiI have written the following function public System.Data.SqlClient.SqlDataReader ExcuteReader(string strQuery, string strConnection) { System.Data.SqlClient.SqlCommand myCommand; System.Data.SqlClient.SqlDataReader myReader; myCommand = new System.Data.SqlClient.SqlCommand(strQuery, new System.Data.SqlClient.SqlConnection(strConnection)); myCommand.Connection.Open(); myReader = myCommand.ExecuteReader(); return myReader; }to return a datareader for me but right now I am facing the problem that it seems this function isn't closing the connection by itself which is resulting in an error saying "Timeout expired. The timeout period elapsed prior to
obtaining a connection from the pool. This may have occurred because
all pooled connections were in use and max pool size was reached" and if I close it manually I will lose the data in the readerso are there any suggestions of what I should do?thank you
