hi
We have use SQL Server 2005 on 64bit windows 2003 server Cluster. SQL instance stop responding for some leaving application interrupted.
In the Sql Err log I noticed the following information memory errors just before cluster issued stop command to SQlsrvres. Lazywriter gave warning that no free buffers found .
While waiting for the fax of instructions to contact MS Support, I thought I would post here (tried several times and no fax...)
We get this message in the log file and then all hell breaks loose until it resets memory. The SQL Service continues working but nobody can connect for about 5 minutes and then is seems to reset itself. This has happened three times over the past two weeks. Only one time it did create the SQLDUMP files but all three occurences have practically the same entries.
We are running SQL Server 2005 x64 SP2 under Windows 2003 x64 SP1. We have 4GB RAM and SQL is configured to use 2GB of it. We have a large number of databases (about 400) on this one instance that experiences this problem. The server itself is not under a tremendous load. All of the databases were recently upgraded from SQL 2000 SP4 32 bit instance. The first occurence happened just days after the migration.

A long time ago I posted this: http://blogs.conchango.com/jamiethomson/archive/2005/06/09/1583.aspx explaining all the different buffer types in the pipeline.
I have to admit I'm still not clear on the difference between a private buffer and a flat buffer though.
Are flat buffers a subset of private buffers. If so, if a private buffer is not a flat buffer - what is it? If not, can a buffer be a private buffer AND a flat buffer?
Some descriptions from BOL are:
Private buffers: A private buffer is a buffer that a transformation uses for temporary work only Flat buffers: Flat buffers are blocks of memory that a component uses to store data
That sounds like two ways of saying the same thing to me! It certainly doesn't distinguish them anyway!
Just seeking some clarification here. If you could whip of a demo package that explains the difference between the two (with reference to the Performance Counters) then that would be great.
I have a package with an XML Task with OperationType = Validate. The source is a string variable and the second operand is a file connection to a schema file. The schema file <include>'s other schemas. I run the package in debug mode in Visual Studio with no errors. I exit Visual Studio. Then I open Visual Studio again and run the package in debug mode like before and it fails in the xml task with error: "Task failed to validate "No schema to use in validation was found.". I don't understand why it fails since no changes were made. The strange thing is that if I click the File Connection Manager for the schema file and click Browse and then reselect the same schema file again then it runs OK. Note that I have to exit Visual Studio and not just close the package in order to repro the error. It seems like exiting Visual Studio frees some resource that is essential to the validation. Reselecting the schema file in the Connection Manager seems to restore the resource. (SP1)
One of my clients has received the following message:
"99/08/10 10:40:15.38 spid2 Lazywriter: WARNING, LRU list is empty (408 free bufs, 3025 total bufs)"
I understand that it has something to do with the caching of data, but how can I fix this error message? Do I need to change the allocation of cache or just add more memory?
We did configure reporting services to use a custom security extension on a Windows 2000 sp4 machine and using IIS 5.0.
The website for reporting services is not using the default website in IIS. It uses IP address : 192.168.1.20 and host header name is rpt2.compagny.com. When accessing the report manager at http://rpt2.compagny.com/reports$sql_2005 from another machine or on the machine where reporting services is installed we get an error message.
Error Message : The attempt to connect to the report server failed. Check your connection information and that the report server is a compatible version.
The RSWebApplication.config file looks like the following :
We already tried replacing the server name with the ip address in both the RSreportserver.config file and RSWebapplication.config file and it still does not work.
here is the logfile information :

What should be the settings in IIS and the configuration files ?
I don€™t know if this is the case but I need some help. We have itanium server with Microsoft SQL Server 2005 - 9.00.3054.00 (Intel IA-64) Mar 23 2007 18:42:19 Copyright (c) 1988-2005 Microsoft Corporation Standard Edition (64-bit) on Windows NT 5.2 (Build 3790: Service Pack 2).
We has had lot of problem with that the sqlserver.exe process hangs 100% cpu. It€™s totally non responsive I€™m not even able to contact the server with DAC. The general solution has been just kill the process. Not nice.
Someone told me they closed there window and lost their query and wanted to know if there was some way to get it back from a buffer or something. Does anyone know if that is possible? I was not aware of anything like that, but the way that SQL caches and buffers things I thought it might be possible extract a query from a buffer or something...?
Occasionally on my SQL 2K SP3 Standard servers. The servers lock up withthe error.LazyWriter: warning, no free buffers found.After that I have to restart the SQLServer service to get things up andrunning. How can I prevent this from happening?Thanks,Ray
I am using windows 2003 server and i have installed SSAS 2005 and configured http request for AS 2005 with this below url : http://www.microsoft.com/technet/prodtechnol/sql/2005/httpasws.mspx. I had tried all the possiblities given in this url. But i am getting like "Test connection failed because of error initializing provider. The HTTP Server returned the following error : Not found" when i create udl file. Moreover i have installed MSOLAP 3.0 and OLAP 9.0 provider and MSXML 6.0 Parser.
Hi,I keep getting this error message for a trans.log backup.Operating system error112(error not found).The disk has about 6GB space free, and the backup should only take upabout 550 MB, so I would think it is not space related but...The disk is NTFS.Any ideas?
I am looking for an API to flush all data in memory held by SQL Serverto disk. Also, is there a tool for SQL Server like eseutil forExchange that lets you correct a SQL database?
I have corrected the problem with named pipes versus TCP/IP but I have found a reference to lrustats stating that page flushes should be less than 100 and free avg less than 10 but my numbers are extremely high. One of the things I noticed upon assuming this job was that many settings were off a bit bit LogLRU buffers were never set.This setting was introduced with service pack 2 with a readme.txt on how to configure. All my references and the ones that I have skimmed through in bookstores do not contain this configuration setting.
Microsoft no longer offers SP2 for download so that I could get the readme.txt. If any of you have this file or service pack laying around, please email it to me so that I can configure. It is suppose to take care of some bufwait errors. I even download the French version to see if it was there and maybe I could find someone with a french background but it did not contain the file. It was in last years Technet CD but my company tossed it when they got the new one. Can anyone help?
Anyone seen this SSIS error when importing data? I have a 64bit quad processor with 8gb and am importing from Oracle 9 using 32bit DTExec.exe from the command line.

I've got a package which reads a text file into a table and updates another. I set up configurations so that I could import it into the SSIS store on both my dev and live servers. Now, I'm getting this error. I tried removing the configs and am still getting it.
I've been through each step and everything looks okay. Does anyone have any idea (a) what's wrong, (b) how to localise the error or (c) get any additional information? Or do I just have to recreate the package from scratch?

I would like to make sure that SQL Server Express is completely free even for public institutions e.g. bailiff office. We (my office) want to use SQL Server Express 2005 at 9 computers for free, is it possible? Can you give me a full answer? Thanks!
Surely not everyone that uses SQL on a shared server has to buy their own copy of SQL Server?
Is there a free utility to copy it from the host to local? I am assuming that SQL management express can not do this (after searching the help for a while... annoying)
I'm executing a stored procedure, before execution the memory used for sqlservr.exe in the task manager reflects about 50mb. but after the stored procedure is executed, the memory used by sqlservr.exe boosts up to 200mb and remains at 200mb even after execution. this causes my pc to slow down. how dow i reset the memory used by sqlservr.exe after executing the stored procedure? any help will be very much appreciated. thank you.
Hello, I am 13 years old and trying to create a mmorpg(massively multiplayer online role playing game) and need a database so people can register, buy weapons, kill other people, etc. The only problem is, I only know javascript and html.

Hi I have a .net 2 website that works from a sql 2000 db. I am building a form that will allow the user to type in any search criteria and based on their input I need to produce some results (that’s the simplest way to put it)I will need to search various parts of my db to find similar sounding information, I was just wondering what is the best way to do this. I had the following thoughts1) Search columns using Soundex tsql function (but not sure how good this is?)2) Remove all noise words from user input (eg, and, or, the etc...) and then use a regular expression to search the fields in the dbAlternatively are their some third party components to do can do this for me Many thanks in advance
does anyone have code that shows how to separate individual words from a sentence.
e.g. i have a list of questions and answers in my database and have the following query for it:
SELECT question, Answer FROM QuestionsAnswer WHERE FREETEXT(Question, 'i want to travel around the world and learn about cooking')
so i want to extend the above query so that takes each key word (travel, cooking, learn) to find out how frequently that particular word appears in the question (for ranking purposes).
I know freetexttable does rank results, but they don't seem accurate enough for what i need to do.
