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.

Hi SQL folks, I've googled for this the whole yesterday and I couldn't find a complete solution. I'm having a sql2005 database in my development machine and I need to copy all the content "Tables, Diagrams, PK columns and other data" to the remote production machine. Using the Import/Export method didn't copied the relationships between tables, also it turned the PKs into just a standard columns Can anyone help?
1.) Can an aspnetdb.mdf database be configured and setup on one server and then be moved to a production server or is there something machine specific that keeps this from being possible? 2.) Is putting this file in the app_data folder something that is used only for SQL 2005 or SQL express? I had to set up a connection string in my SQL 2000 installation to get the connection to work. Thanks for any input! Colelaus
Hi everybody. I have such problem: After I move my integration services packege to another machine it failed. I tried to recreate connection manager, but result is the same. If I create a simple SQL task in that package and try to execute it - it fails with info:
SSIS package "Main_Package.dtsx" starting.
Error: 0xC00291EC at Execute SQL Task, Execute SQL Task: Failed to acquire connection "SRV-DSA3.TIA_EXTRACTS_OriginalData.sa". Connection may not be configured correctly or you may not have the right permissions on this connection.
Help! I am using Script Transformation to output a new column as image[DT_IMAGE] field to store serialized object. In the VB script, the sample code as
The package always runs fine on my developing machine and will halt on other machine at AddBlobData after certain number row records were processed. I am stuck here. Anyone has any suggestion?
What I need is reading data from mutiple tables in one database and writing into a single table in another datable. In order preserve all the columns data, I use input column fields to construct a new object and then serialize it, and store the serialize data into detination db table. (The object and serialization function is coming from c# dll.)
Dim b As BusinessLicense = New BusinessLicense() b.ApprovalDate = Row.approvaldate b.BusinessId = Row.busid b.BusinessName = Row.busname b.NaicsCode = Row.naicscode b.NaicsDescription = Row.naicsdescr b.OwnerName = Row.ownername b.Phone = Row.phone b.Pkey = Row.pkey b.RenewalDate = Row.renewaldate b.StartDate = Row.startdate b.Suite = Row.suite
Row.serializedobject.AddBlobData(Serializer.Serialize(b)) '''----This is blocking line Row.infoType = BusinessLicense.TYPE
Both machine is xp with sp2. and standard SQL Server 2005 - 9.00.1399.06
Hullo all I have two machines, One is a standalone machine and the other is on a domain network. How can I run a stored procedure/job on the standalone machine from the domain machine ? running the procedure as a Domain user results in a failed job/stored proc. also creating an sql login and attempting to run it as that user also fails. How can I solve this problem ? please e-mail me at wayde@sunnygrp.com if you have any thoughts...
Hi All;We are going to change our application server. We will copy all of ourDatabase from Mic 2000 Server OS to Mic 2003 Server OS. I found anarticle that how to move all the folders from same OS. My question isthat Would the 2003 OS be a problem when we copy all of the MC SQL 2000folders to New OS ? Has anybody done this before? Could you gimme yoursuggestions please?ThanksASA
If I use GetDate() function from client machine (using "\ServerMachineSQLExpress" instance from client machine "ClientMachine"), then from where I will get the DateTime value ?
I was wondering if there was any white papers on the migration part from microsoft? Apparently the situation is like this Currently installed MOSS 2007 in a testing pc as application server. This application server will refer another testing database server which running SQL Server 2005.
Now, wanted to move this 2 temporary server into another 2 new servers. Correct me if I'm wrong, it cannot be done by using image like Norton Ghost due to difference hardware spec.
So, if I install another fresh copy of MOSS2007 & SQL server 2005 in that 2 new servers, how can I migrate the contents, documents, etc from the testing database server?
It would be great if someone can show me the links to kb article. Thanks
update xxx_TableName_xxx set d_50 = 'DE',modify_timestamp = getdate(),modified_by = 1159
where enc_id in

'D7FBD152-F7AE-449C-A875-C85B5F6BB462')
but From linked server this takes 8 minutes????!!!??!:
update [xxx_servername_xxxx].xxx_DatabaseName_xxx.dbo.xxx_TableName_xxx set d_50 = 'DE',modify_timestamp = getdate(),modified_by = 1159
where enc_id in

'D7FBD152-F7AE-449C-A875-C85B5F6BB462')
What settings or whatever would cause this to take so much longer from the linked server?
Edit: Note) Other queries from the linked server do not have this behavior. From the stored procedure where we have examined how long each query/update takes... this particular query is the culprit for the time eating. I thought it was to do specefically with this table. However as stated when a query window is opened directly onto that server the update takes no time at all.
2nd Edit: Could it be to do with this linked server setting? Collation Compatible right now it is set to false? I also asked this question in a message below, but figured I should put it up here.
I am working in a distributed environment, I verified msgs have been successfully send from server1 db1 to server2 db2, but I still get the following error msg from the sender server through SQL profile:
Connection attempt failed with error: '10061(No connection could be made because the target machine actively refused it.)'.
Any help would be greatly appreciated.My problem is that I need to set up a backup SQL Server 2000 machinewhich can be used in case of a failure to my primary. All databases(30 as of now) must be an up to the minute exact copy of productionand include most recent changes in data as well as any structurechanges (Tables, Views, SP's, Triggers, Users . . etc).When I tried this using Transactional Replication, the replicationprocess gets fouled up once I introduce any kind of structure changesto the DB. I've considered the idea of doing periodic backups andrestoring it to my backup SQL server, but this does not give me theconcurrency needed with 0 latency.I've seen articles that recommend using Transaction Replication with'Scheduled Table Refresh', and also doing database dumps to restore onthe backup machine, but I have not been able to find any documentationregarding this to try out. How can I implement this type of backupstrategy in SQL 2000?
Installed SQL Server 7 on Win 98 machine, keep getting errors:Unable to connect to server servername:
Server: msg 11, Level 16, State 1 [Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]General network error. Check your network documentation.
Did the troubleshooter on M$ Knowledgebase, still did not work. Still get the above and this error: General network error. Check your network documentation. ConnectionOpen (connect())
Went to install SP3, and now It won't let me continue without an sa password. I never had a password to begin with.
Im getting an error when i try to connect to my MS SQL database
0x80040e21 .... multiple-step ole db operation generated errors ....check each ole db status value
this code works connecting to database via web hosting, only things i changed was to replace the server with "(local)" [also tried ip no joy there either] and add integrated security to the connection string
ms sql server and IIS, personal web server all on same laptop, i can access the same database with same details no problem to login it gives up on the subsequent login
code (generally)
Set objconn=Server.CreateObject("ADODB.Connection") objconn.ConnectionString="SERVER=(local);Database=blah;uid=blah1;pwd=blah2;Integrated Security=true;"
This may be a stupid newbie question, but being that I'm not a DBA I'm going to ask it anyway.
We discovered a problem with a clients server (Windows 2003 SBS) when we tried to install Veritas Backup Exec. Backup Exec requires an instance of either SQLMSDE or full SQL. This server has full SQL 2000 sp3a installed on it with a working account application. When backup exec trys to create it's instance it fails.
Investigating further...when I go into Enterprise Manager (logged in as Domain Admin) I get an error when I select the local server.
I.E. "A connection could not be established to (LOCAL). Reason: Data source name not found and no default driver specified. Please verify SQL Server is running and check your SQL Server registration properties. blah blah blah.
Okay the server is running. The accounting application (client/server) is still working. I right click on the server and select "New Server Registration" for the field "server" I click the browse button and the "Active Servers" box is empty..:shocked:
I went to check the "Data Sources" under drivers, that field is blank. (no drivers installed). I downloaded MS's component checker and it says "MDAC 2.8 on Windows server 2003 sp1" is installed.
At this point I have exhausted my knowledge of MS-SQL server. My goal is to get BackupExec installed and NOT break the existing accounting application.

I'm trying to figure out how to retreive connection strings from the machine.config instead of storing the conn strings in a *.dtsconfig file. The reason that I'm trying to use the machine.config is for the simple reason that I'll be able to manage all of the conn strings in one location on each server. (Instead of mutliple dtsconfig files.) Is it posible to utilize the machine.config in SSIS? If so, could someone explain how, or better yet, have an example?
hi i'm having this error on my application"cannot allocate more connection.connect pool is at maximum increase max pool size" the proble is when i do testing this error does not apply it only Appears when the application is been used by many people How can I resolve this? Thanks

Hello, I am not sure if this is the right forum. This is the first time that I have seen this error, No connection could be made because the target machine actively refused it I have a web app that when some one inserts text in a text box and clicks a button it creates a new web page and a new table in the database. Up until this point it has always worked. A datalist returns the data. In the datalist there is a hyperlink that when clicked takes the client to the new webpage. But for some reason it is not working now and that is the error above. I am lost. Any help appreciated. Thanks Matt

I installed SQL 2005 Developer Edition on a Small Business Server 2003. It worked properly for a period of time. However, I cannot open the Management Studio today and it shows a message "Connection to target machine could not be made in a timely fasion.". Initially, I installed the SQL 2005 Evaluation Edition. After passing the evaluation period, I un-install the Evaluation Edition and then install the current Developer Edition. What's thing can I do?
I've SQL Server running on 64 bit. When I schedule a package to run every night which has excel data transformation, it fails. Initally I had a problem running through BIDS also but then I found in project properties you can switch this off by specifying property Run64BitRuntime by false. After going through some forums, many have suggested that when scheduling a package, modify the command arguments to run as 32bit runtime. These command argumnents can be generated from making use of tool DTExecUI.exe Even after using generated command arguments from this tool, it doesn't help.
Below is my command argument and the error message generated.

Can we have Reporting Services having its database on a server and distribution server (http://IISserver/Reports) on another server?We dont want our database server to have IIS and dont want SqlServer installed on our IIS server kind regards
I am having an asp.net web site hosted in my machine's IIS (5.1). This aspx files are accessing data from an sql server 2000 database located in another machine. While i am trying to open a connection from the aspx files to the database, an error showing login failed for that user. Not a trusted sql server connection. so i unchecked the "allow anonymous access" in the directory security. But now its working from my machine (the web server, localhost). but when i try to access the aspx files from another machine with my system ip, the same error exists-Login failed for the user and not a trusted sql server connection.

But, I received the following error on trying to process a cube from BI studio is -

I have a SQL Server 2005 box that was moved from a domain environment to a non-domain environment and was never dropped from its original domain before moving over. Subsequently a new domain was created at the data center this SQL Server box now resides in. The machine was dropped from its old domain and joined to the new one.
All the while the service accounts were set to the local admin account. When I tried to start the Configuration Manager I got the message "Connection to target machine could not be made in a timely fashion.". I read some blog entries and tried changing all the service accounts to Local System and the error message still came up.
All of the SQL Server services run fine. It is just this management console that I cannot open. I wasn't with this employer when this box was moved to the data center so I do not know if it worked prior and there isn't anyone here that could give me its history.
