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?
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 overwrote rsreportserver.config with one from a different installation and that killed my RS because of the encryption key inside that file. Is there any way to generate that file for current install or do I have to reinstall the whole thing now?
When running the DBCC sqlperf (LRUSTATS) command I get an extremely high value for the Avg Free Page Scan. Typically, this value was between 1 and 2 for our SQL 6.0 Server, but in upgrading to SQL 6.5, it has jumped to about 200. Recently, I noticed another value looks suspect. The Max Free Page Scan is equal to 1, obviously not the *Max* value if the average is 200.
I know that others have seen this same behavior both in this group and in the microsoft newsgroups. It seems as though these values have been reversed or since every example I've seen posted by others has a 1.0 value for the Max, this parameter is not working at all.
An example of the output follows:
Statistic Value -------------------------------- ------------------------ Cache Hit Ratio 98.8573 Cache Flushes 4588.0 Free Page Scan (Avg) 184.768 Free Page Scan (Max) 1.0 Min Free Buffers 2048.0 Cache Size 24883.0 Free Buffers 2174.0
If anyone has information on this, or knows where I can go to get more information, it would be appreciated. Thanks, - Craig
hi, here is the situation, my system has the following specks hard drive = 45GB memory = 1152 mb Opsystem = win NT 4.0 application on the NT is ftp server and SQL server 6.5
I am having a tough time retrieving a simple query from a 11 million records.some of the feed back from the newsgroup is that I do not have enought memory. Is there a formula to use to figure out how much memory should allocate to the sql server? what if I allocated too much memory, does that affect the sql performance in a negative way? Please help...... I can be reach at a.alhussein@mci.com
The encrypted value for "logoncred" configuration setting cannot be decrypted. (rsFailedTodecryptConfigInformation) ***********************************************************************************
Please help thank you very much for the information.
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 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?
hi We have use SQL Server 2005 on 64bit windows 2003 server Cluster. SQL instance stop responding for some leaving application interrupted.

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.

I have just finished installing SQL 2005 Ent Edition on Win 2000 Adv Server, SQL2005 SP2, and SP2 Hotfix KB934458. After the installation, I could see and configure all services via SQL Configuration Manager and SQL Server Surface Area Configuration tools. This worked for a couple of days and now both configuration tools no longer detect SQL2005 components. SQL Server Surface Area Configuration issued an error that said "No SQL Server 2005 components were found on specified computer. Either no components are installed, or you are not an administrator on this computer. (SQLAC)". SQL Configuration Manager did not list any installed services. I don€™t know what caused this. Anyone has any idea? Please help! Below is the Installation Report which shows installed components.
===================================
The following components are installed on this server
Hi --I was wondering if this is a bug when I add new data in my table SSIS Confiurations and give wizard a new Configuration filter the package configuration wizard can not see the new values --the old values from the previous configuration are still showing---is there any known workaround or forced refresh I can do
thanks in advance Dave
Background:
SQL Package Configurations are most important because they provide the possibility of a central configuration store for your entire enterprise!!!!!!!! and is in my mind the only way to go
USE [ETLConfiguration] GO /****** Object: Table [dbo].[SSIS Configurations] Script Date: 05/23/2006 13:34:35 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[SSIS Configurations]( [ConfigurationFilter] [nvarchar](255) COLLATE Latin1_General_CI_AS NOT NULL, [ConfiguredValue] [nvarchar](255) COLLATE Latin1_General_CI_AS NULL, [PackagePath] [nvarchar](255) COLLATE Latin1_General_CI_AS NOT NULL, [ConfiguredValueType] [nvarchar](20) COLLATE Latin1_General_CI_AS NOT NULL ) ON [PRIMARY]
It seems to me, that the best way is to have one Environment Varible containing the name of the SQL Server, so that you can look up the configuration in the SSIS Configuration Table when you run the package.
Is this the preferable way of doing it ? I would like to hear some positive/negative comment of why chosing a configuration type instead of another.
It seems to me that putting all of the configuration in the Environment variable is harder work but most secure (server breakdown vs table corruption/database error...)
I am creating a windows application to manage my ssis packages.
My SSIS packages use package configurations, and by default connect to the "SSIS Configurations" table in sql server.
However, I want it to connect to a view instead of this table, so i create a view "vwSSIS_Configurations" and point the package configuration to use the view in sql server.
The application SHOULD be capable of altering the package configuration's configuration and switch its connection between the default "ssis configurations" table, and the view.
Is this possible? I cannot think of a way which I can have my application switch the package configuration's connection.
In my ASP.NET app, I'm executing a stored procedure via a SQLCommand the searches a customer database. I believe the default timeout is 90 seconds. I'm curious of what happens to the SQL Server Stored Procedure after timing out from the ASP.NET application. Does it timeout at the same time or do you have to set up a value in SQL Server?
I have a Sql7.0 box inside a firewall and Sql6.5 outside the firewall. I would like to use a DTS to transfer data. I followed the KB artice on configuring SQL to listen on a specfic port, but still have problems. I added entries in Client Config on both machines. Still no luck, looks like the 7.0 box not talking on new port...
I have a question about SQL Server configurations, especially those related to memory.
We are running SQL 6.5 SP5a on a 400 MHz machine with 1GB of RAM.
Our memory setting is 409600 (800 MB), which according to all the documentation that I have read is a conservative figure. The problem I believe is in our settings for Locks and Open Objects. The settings that are in place are Locks=3000000 and Open Objects=500000.
I am not a DBA, I am a developer, but have somehow become part of the DBA team. These settings seem out of proportion with the memory we have. The reason given for 3 million locks, by other members of the team, is that our biggest unit of work is a query that performs a select into of approx. 3 million records. To further compound things, we are getting an out of memory error on the server after only a day of running.
The other members of the team have implemented a start and start of the service to occur at 4 AM every morning, but I am convinced that this is not the appropriate action, but they will not action any configuration changes unless I can prove that it will help the memory problem and not effect the queries.
If anyone has any information or links to information regarding Locks and how they relate to query performance, or at least a sample of what your settings are it would go a long way towards convincing either myself or the rest of the team what direction to go.
I have SQL Reporting Services 2005 installed. When I go into the SQL Reporting Services Configuration Manager I immediately get an error that says that "No report servers were found on the specified machine" then Details: Invalid Namespace.
The machine that it is running on is our report server. The name in the Machine Name says the name of the report server not the name of the specific machine so maybe this is the problem? I think the name of the report server should go in instance? Problem is that it won't let me change anything and it just gives me that error and everything else on the screen is disabled.
Hey guys, got a question regarding hardware configuration for a new SQL server we are installing here. We are migrating from a Windows 2000 standard, SQL 2000 standard box with 4GB of RAM to a Windows 2000 datacenter, SQL 2000 enterprise box with 32GB of RAM.
What would be the best way to set this up in Enterprise Manager? Should I just let SQL Dynamically use the RAM or should I select a fixed amount? Also with the processors, should I allow SQL to use all available processors or just 3 of the processors? Also with such a large amount of RAM, I've read people setting there pagefile to 0 so there is no load on the hard drives.
We are running SQL 7 on a server, and are moving to a new server and will beupgrading to SQL 2005 at the same time. Currently, both the old and the newservers have two drives, one for programs and one for data.With the current configuration, SQL 7 and the data are both installed on thedata drive, in the MSSQL7 directory. Our sys admin wants to install SQL 2005on the program drive of the new server, while putting our databases on thedata drive. I argue that if SQL itself is on the program drive, then thesystem databases will be in one place, while our databases will be inanother. So I'd prefer to have SQL 2005 installed on the data drive, as itis now.I'm interested in any feedback regarding what you guys think is the betterconfiguration, and also if there's any performance hit from having theprogram and the database on two drives of the same machine.Thanks,Neil
In my Package Configurations, I have three different configurations. Two are of the type, SQL Server and one of type XML. I want to get the currently used Configuration name, Configuration String and the configuration type in my Script Task code. Can anybody help me with this code. Thank you.
We store our configurations in a SQL Server configuration table. We have SSIS packages that can be used in different senarios. Each of these senarios requires different configuration values.
Is it possible to change the SSIS configuration key used for a package at run time? i.e. we'd like to be able to use a job that says run this SSIS package but use configuration values with that name.
I've installed SBS 2003 with SQL 2005. The MBSA shows that the SQL service and agent should not be run as a Local System or Administrator. I've tried to create a new user and start the service with the new user, but no matter what I do, I cannot start the service with the new user. I've tried to add the user to the SQL* groups and Domain Users group, but no luck. I've tried adding permissions to those groups to all the SQL directories, but again, no luck. I'm getting error 5 - permission denied. Anyone got a good HOWTO?
Hi, I am very new to SSIS and SSRS.I just installed in sql server 2005 professional in my office machine. I am going to work on SSIS and SSRS. My machine itself will be the server.Could you please tell me what are the configurations I should do?.. Thanks in advance. -Selva
In my package I am using some 3 to 4 database connections. Hence I can say 3 to 4 connection managers I have. Other than that I have 2 Flat file connection manager.
What will be the best way to configure the same? and Please let me knowwhy that is the best choice.
