hi,
Does large number of connections to a sql server result in slogging queries??
by large number of connections I mean in the range of 2000 to 2500 connections to various databases on the same server.
This happens on the production database, if I download the copy of the database and run the specific queries on the local box it hardly takes 1 second to execute, whereas on the production box it takes about 45 to 60 secs, i m working on the indexes part... was not sure whether number of connections to a server affect the performance of the queries or it is just that the indexes need defragmentation...
I would like to know does it exist a relation between number of licenses (per server) entered when installing SQL Server and the maximum of connections obtained by @@MAX_CONNECTIONS ? how can i get the information about the number of licenses after the installation ? Thanks.
I am building a package that involves copying 36 tables from an Access database into like tables in SQL 2000. Many of these tables require transformations and some require lookups. The number of records per table ranges from 4 to 4000. My question is, is it better to have a set of connections(one to Access and one to SQL for each table or one connection for all or some other approach.
Hi. I have to buy a license for MS SQL Server 2000 and I need to know how many active connections I will need. I could try by running the application with multiple users and see how many connections there are.
The questions is: How can I know the number of active connections to the Server?
Is there any way to know the number of current connections to an SQL Server Database? Also how can one change the max pool size (for the number of connections allowed to the database)?
How do you find out the current number of connections to a SQL Server 2005 instance in SQL Server Managment Studio? I need to see if my number of connections is exceeding my Maximum Worker Threads.
I'm currently in the middle of building quite a large CMS using ASP.NET and MSSQL2K and have began to question if the amount of queries I am using for one page to be built is too many?
For one page (View Forum) I am getting all of the templates and checking access then pulling a list of threads, getting the first and last posts, then user info for the first and last posts... anyway to view 10 threads on the page the number of queries comes to about 54 and the page takes 0.064 seconds to load.
My question is, Is this to many queries to be running for a single page load? All queries are using Stored Procedures.
We are busy designing a generic analytical system at work that willhold multiple analytic types over time. This system is being developedin SQL 2000.Example of tableIDENTITY intItemId int [PK]AnalyticType int [PK]AnalyticDate DateTime [PK]Value numeric(28,15)ItemId - the item for which the analytic is being storedAnalyticType - an arbitrary typeThe [PK] tag indicates the composite primary key.Our scenario is the following:* For this time series data, we expect around 250 days per year(working days) and the dataset could extend to over 20 years* Up to 50 analytic types* Up to 20,000 itemsLooking at the combined calculation - this comes to roughly somethinglike25 * 20,000 * 50 * 250 or around 5 billion rows.We will be inserting around 50*20,000 or around 1 million rows each day(the inserts will take place in the middle of the night (outside themain query time) - this could be done through something like BCP orBULK INSERT.Our real problem is we have not previously worked with such largetables before and are nervous that our system is going to grind to ahalt. Our biggest tables are around 20 million rows at the moment.Scanning through google and microsoft's own site we have found aparititioning method that is available.http://www.microsoft.com/resources/...art5/c1861.mspxHaving experimented with the above system it seems rather quirky andlooking at the available literature it seems that this is not moreeffective than a clustered index as far as queries go.It needs to be optimized for queries like:Given the ItemID and the AnalyticType search for a specific date or aspecific range of dates.If anyone has any experience or helpful suggestions I would reallyappreciate it.ThanksA
A select query returns around 1 million rows. The column in the WHERE condition is indexed. This query takes nearly 1 minute for returning the all the records. Is this normal ?
Does the number of records returned affect the performance inspite of the indexing ?
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
I am using SQL 6.5 and I would like to know (using Isql/w) the number of users connected to my server at any given time. Thanks for your help in advance.
Does anyone know how to change the number of conccurent connections on SQL Server 7. We have purchased 10 additional licenses and I need to change the concurrent users from 10 to 20. Any help would be appreciated. Thanks
I am new to SQL Server 7 and am not sure how to handle setting up/importing FoxPro databases. The consultants that setup the database before me have combined all of the FoxPro databases into one big database in SQL server. The reasoning was that for user applications to have access to different databases in SQL they would need a connection for each database they are using, so if all the data is put into one database then the user would only have one database connection instead of 6 or 7.
Does this make sense to anyone? Someone else thought that this might have been true is SQL Server 6.5 but not in SQL Server 7.0. Any help will be appreciated.
I need to insert a very large number of rows into a table (in SQL Server 7.0) using ADO. Could you please tell me i there is a way for FAST insert, something similar to BCP ... or any other way of inserting large number of rows efficiently
Hi gurus, I'm creating a web application where I will have a large number of tables (between 10k and 20k), this is done for the sake of scalability as tables will be moved to different database servers as the application grows and also for performance (smaller indexes). I'm worried though how having a large number of tables could affect the performance of SQL Server as the application will start on one single database server. I tried to find some resources on that on the internet but couldn't find any.
I would really appreciate if you can give me some advice and if you have any good links that would be great...
For anyone with a larger number of databases (500+): How many do you have in a single instance. If you are using multiple instance on a single server, how many dbs per instance. This is why I'm asking
We are experiencing 701 "out of system memory" and temporary (usually) system freezes when the error occurs. We have 32bit 2005 version 9.00.2153.00, 32GB of memory, AWE enabled, quad dual-core 3GHz hyperthreaded server. Nether the bPool or VAS show any pressure when the "out of system memory error" occurs. Since this error usually indicates a VAS problem we tried increasing VAS to 1GB w/the -g flag. It made no difference. PSS has been working on the case for 3 weeks. They dont seem to be finding any evidince of memory pressure either. When I last spole to the escalation engineer yesterday it seemed that they are going to recommend reducing the number of databases on the server. I asked for clarification as to whether we are hitting a 32 bit barrior, an instance limitation, or both. I am awaiting the answer. How many databases do you have on your server? We had between 1700 and 1900 (the number varies) at times when the error occured. We are now at 1500, and have not had the error in the 2 days since reducing the number of databases...

The DB I am working with has about 10 tables and some of the tables have 200,000 to 500,000 records. All tables have a clustered index on the primary key.
I performance during INSERT could be better I think - I add thousands of records at a time from many connections.
Is there a way to defer the update of indicies? So that, I can update the tables and then let the indicies regenerate ?
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 ?
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.
I have a Sqlserver 6.5 production server used for web based applications Compaq 5500 4 GIG RAM, 4 processor
Sql Memory config on that server is 1048576 (which is 2048 MB) and the run value is 640000 (which is 1250 MB). runvalue for user connections was 500
We have only 90 user connections may increase upto 100 depends on the connections. We don't have any overload on that server.
Error: I was seeing "unable to connect maximum no. of 500 configured user connections are already connected" in the error log.
Action Taken:
I increased the user connections to 600 and rebooted the server. Immediately the same error I can see in the error log. But we have only 20 user connections at that time. I can able to connect.
I have datagrid that needs to display a log table which has more than million records. Since it it huge number, it is not possible to get dataset using "select * from log_table" to fill and to bind to datagrid.Is there anyway to display first 100 rows on first page and show next 100 rows if use clicks on page 2?Thank you very much in advance!Justin
Hi I have created one store procedure which handles global updates I am using cursor to fetch one be one row for updating (It is required for implementing business logic)Now when i execute this store procedure ---it gives me dedlock error , I dont know why i m getting this error(Approx number of rows 1.5lakh)if then i removed unnecessary records from table (Approx -50000) it works fine,Is there any way to handle itI am calling this storeprocedure from my window service.please give me a good solution if possible
We have a Windows App and Web App that share business objects which points to a single database. When a Windows user logs in, an average of 50 processes are created in the first few seconds and never go away. The details window is blank and they all remain sleeping from that point on.
I have stepped through the code to see if there is anything odd going on but most of the processes are created when validating the number of parameters the stored procedure has or the length of the stored procedure name. This translates to 1000-1500 processes on average.
Is this normal? Will it hurt performance? Is there a way to remove them?
