Reusing Connections
Jan 2, 2006Every time my asp.net app needs to open a connection, it tries to establish a new connection with the mssql server. I´ve already set the max pool size property in the connection string. After that, my app raises an "time out"error saying it couldn´t obtain a connection from the pool. The problem is that I have a lot of iddle connections. With the Enterprise Manager I can see the status of the connections. They´re all the same "awaiting command". How can I reuse this connections? I know that the connection string must be the same for all connections and it is. I´ve set it in the web.config file. If I remove the max pool size property from the connection string I get a lot, I mean A LOT of connections with the sql server. Any ideas?

Jul 20, 2005Just a quick question about connection management. My application willnever need more than 1 or 2 connections about at any given time. Also, I donot expect many users to be connected at any given time. For efficiency, Iwould like to keep connections alive throughout the lifetime of the objectsrequiring them, rather than opening a new connection, executing code andthen closing it again. What is the most efficient way of doing this?Should I perform the open/close or just one open when I create the objectand a close when I dispose of it?

Feb 1, 2008We've built a web site with more than 500,000 unique visitors per month.
We are not having any performance issues.
However, I've asked my ISP to send me the no of open database connections.
He told me that there's around 80 open database connections.
For info, we are using dotnet with DAB 3.0 and SQL server 2005.
Is the no of connections normal ?
Knowing How Many Connections Are Open?
Feb 1, 2006How can I know how many connections are open at a given point of time while I am testing an ASP.Net application? The application uses SQL Server 2000 as its database.
Connections Remain Open In SQL Server 6.5...
Feb 19, 1999Would be very pleased if anyone knows a solution to my prob.
I connect via ODBC (ADO) within Active Server Pages with an SQL Server 6.5 database.
The connection is opened at the top of the pages that need the database, and closed at the end of each individual page. Thing is, the connections for one single user are max. around 3 connections (checked that in Performance Monitor), no matter how many times the user opens his browser with the application. However, when say 20 users log on, the max. number of user connections as configured is reached within no time! The connections are not being closed (even with connection pooling on, they increase like hell!).
The only way to close them seems to be stopping the MSSQLServer service, but that's something ya don't want, of course.
It's jut plain crazy to increase the number of user connections to around 250 for about max. 80 user connections at one time...
I would really appreciate your input.
Thanks in advance!
Best regards,

How Many Open Connections Does SQL Server 2005 Express Allow To .mdf File
May 17, 2007Hi Guys, how many connections does sql 2005 express allow to .mdf file. I stumpled on info on a microsoft site (actually a forum post on msdn) that sql server express allows only a single connection to an .mdf file.
Iam intrested in this because i developed reporting services reports in BIS and iam having problems. If i run a report from report manager, i have to wait for close to 20 minutes before i can be able to run my asp.net application agian. Else if i insert data or retrieve data from my asp.net application, then i have to wait again for 20 minutes or more before i can be able to run my reports else i will get an error that a connection can not be made to the database or that the database is being used by another process.
So in all cases, i have to wait for 20--30 minutes before a connection can be made to the .mdf file. i.e after running a report or after inserting or retrieving data from the database through my asp.net application.
Iam using sql sever 2005 express with advanced services and visual web developer on windows server 2003.
Any ideas or help.

I have this SP below, and I am trying to reuse the value returned by the Dateofplanningdate column so that I don't have to enter the code for each additional column I create. I have tried temp tables and derived tables with no luck.

Reusing Dialogs Causes Blocking
Oct 23, 2006I was looking at a means of reusing dialogs.
The attempt I tried was looking up an existing dialog in the conversation_endpoints.
However on doing a scale test I would that the non blocking I was hoping wasn't happening. Even through I was giving each spid a new dialog by using a conversation_group_id related to the spid. I found that the following SQL was blocked by a transaction that contains a begin dialog. This suggests the locking on conversation_endpoints is too excessive.
select top 1 conversation_handle
from sys.conversation_endpoints ce
join sys.services s on s.service_id = ce.service_id
join sys.service_contracts c on c.service_contract_id = ce.service_contract_id
where s.name = 'jobStats'
and ce.far_service = 'jobStats'
and (ce.far_broker_instance = @targetBroker OR @targetBroker = 'CURRENT DATABASE')
and ce.state IN ('SO','CO')
and ce.is_initiator = 1
and (ce.conversation_group_id = @conversation_group_id )--or @conversation_group_id is null)
and c.name = @contractName
Reusing Configuratin Filters
Apr 30, 2008In the Package configurations wizard, I am trying to edit an existing configuration using the edit button. In the Configuration Filter, I get the list of several filters (the filters which were used for other packages). Whe I try to reuse an used filter, it is forcing me to set a new value and when I go back to SQL Server tables , I see the old value has got erased.
Can I not use an existing filter?. Do I need to use new filters for every new package?.
Thanks.

Avoid Reusing Query Plan..
Mar 23, 2004Hi,
I'm trying to test some queries in SQL analyser without reusing the query plan (already cached). I know that there is a way to avoid that but I don't remember right now. Another option would be to restart MS SQL service but I don't want to do that.
Any thoughts...?

Reusing A Single Conversation Handle
Aug 30, 2007Hi
I have a replicated table that has a trigger attached to the it. The trigger fires off a service broker message for inserts. Originally for every insert, I would begin a conversation, send, and end the conversation when target send an end conversation. Since replication process is only using a single spid, I would like to reuse 1 conversation. the following is what I have for the send procedure in the initiator. I check the conversation_endpoints for any open conversation, if it's null, I start a new conversation and send else just send with the existing conversation. Is there anything wrong with this code? What could cause the conversation on the initiator to be null if I never end the conversation on the initiator side? thanks
DECLARE @dialog_handle uniqueidentifier
select @dialog_handle = conversation_handle from sys.conversation_endpoints where state = 'CO'
IF @dialog_handle is NULL
BEGIN DIALOG CONVERSATION @dialog_handle
FROM SERVICE [initiator]
TO SERVICE 'target'
ON CONTRACT [portcontract];
SEND ON CONVERSATION @dialog_handle

View 2 Replies View RelatedWhy Is Sys.conversation_endpoints Filling Up Even When Reusing Dialog Conversations
Aug 5, 2007Hi! I'm wondering why is my sys.conversation_endpoints table inserting a new row for each message i send even when i reuse conversations?
when i send the first message i get the first row in the sys.conversation_endpoints with a uniqueidentifier for the conversation_handle. this uniqueidentifier is then saved in the table which i query the next time i send a message to reuse the dialog conversation.
But even though it looks like the uniqueidentifier is reused i still get a new row for every message i send with a different conversation_handle?
this happens in both target and initator db.
I've tried to understand this by i don't.
Also for the moment i don't end conversations. But as i understand it this shouldn't matter.
Also the message successfully arives to the target and sys.transmission_queue is empty in both databases.
Neither queues have any error messages in them.
Thanx
Reusing Package Configuration In Child Packages
Feb 1, 2007I currently have multiple (parent and child) packages using the same config file. The config file has entries for connections to a number of systems. All of them are not used from the child packages. Hence, my child package throws an error when it tries to configure using the same config file because it can't find the extra connections in my connection collection.
Does anyone have any ideas on the best way to go about resolving this? Is multiple config files (one for each connection) the only way?

View 3 Replies View RelatedCaching Or Reusing Parameters Populated With SqlCommandBuilder.DeriveParameters
Mar 3, 2004Hello,
I have a real heartache with runtime parameter interogation on my DB.
Sure I get the latest and greatest and sure I don't have to type in all those lovely parameter types..but...the hit I take on performance for making no less then 3 DB hits for each SqlAdapter is unreasonable!
So ...I like the idea of maybe calling it once for all my stored procs on application startup...and then maybe saving this in CacheObject.
My problem is that I can't see where you can even serialize a SqlParametersCollection or even for that matter assign it to a Command object. Can you cache a command object ?
LOL
I think I may just have to write some generic routine for creating and populating my command objects based on a key (type) and then use that to fetch my command.Update,
command.Insert and command.
I would like to use the new AsynchBlock to do the fetching of the stored proc parameters and then just pull them from the Cache object....put a file watch so that if the DB's change my params it re-pulls them again.
*nice*.....
Then I get the best of both worlds...caching...and no parameter writing...

Leave The Connection Open Or Always Open And Close Immediately?
Jun 7, 2006Hi there,
I got an approach like that:
1) Read something from DB - check the value, if true stop if false go on2) Read the second Value (another SQL Statement) - check the value etc.
Now I could open the connection at 1) and if I have to go to 2) I leave the connection open and use the same connection at 2). Is it ok to do that?
The other scenario would be opening a connection at 1), immediately close it after I read the value and open a new connection at 2).
Thanks for the input!

Some Ms SQL Connections
Dec 27, 2007Hi I have some simple questions of for MS SQL. Say I have a database with a table Called Company. In this table I have Employee's with these columns(EmployeeID<PK>, FirstName, LastName) Now I am inserting some data like this.EmployeeID FirstName, LastName------------------------------------------------------- 1 Bob Smith2 Joe Mitter Now Say I have this situation(this will look weird for this example but for another examples and the stuff I am working on it make sense). Say I have a new Employee Called Jessica White. Jessica must be the second record. So I need to insert it between the 1st and 2nd record. Like I said I am very noob at doing this stuff so I am not sure how I would do it. I first was going to my table and then went to modify. This brought up a blank grid with all my column names. I then started to add all my data in. I found out later to make my life easier I need to enter in certain spots null rows in it to help with formating(otherwise I would have had to figure out a way to do make null rows with c# code). I then went back to this grid and I tried to add a record before the data just like you if you used excel. I quickly found out you can not do that. This resulted me having to recreate the table and reput the all the data back in(this told me I was doing something very very wrong). I was then thinking of writing it with a query and I been playing around with it and still running into problems like say I had a table called test with a coloum called id<PK> and testss(yes bad names just playing around though).So if I did something like this:INSERT INTO testVALUES(2)INSERT INTO testVALUES(1)SELECT * FROM testNow I am trying to figure out how to insert something between rows 1 and 2. Would I have to drop the table or delete all the data and then run a saved copy of my script with the added change or what?My second question is what is a good site that has examples of all the commands(I don't want to read a book on it I have had a oracle sql course and well it was just boring and I did not learn too much.). I think the best way for me to learn is just continue doing my site and picking it up on the file and when I got a problem read about it and ask on the forums. Thanks
