Hi,
Is 'sqlserver.exe' the only windows process does everything for that
instance of the database?
Please explain in details the SQL server process architecture.
Thanks

I am replacing the corporate SQL Server at work. The new server will have 6 striped disks of 160G with about 4G of RAM. The current SQL Server currently has two instances which run web applications and a small database warehouse about 6G. Analysis Services is also installed.
Due to a couple of new apps being added to the server and the SQL Server 2000 enterprise license we acquired, i was thinking of adding 2 more instances so that the applications can be independently managed in terms of restarting the SQL Server. I also would like to permanently fix the memory settings on each instance to give more resources to more important applications. The log and data files would also be spilt onto 2 separate hard disks. i understand there are implications on performance such as CPU etc. Is it normally advisable to have more than 1 or 2 instances ? Most of the applications are not very CPU intensive. What other implications or performance issues would l have ?

Solutions are easy. Understanding the problem, now, that's the hard part
We are designing a SQL Server architecture that will need to handle a lot of inserts and many users.
We are not sure what approach to take if we should build a distributed server architecture with a Single Master SQL and many Slave SQL Servers.
Or if we should get a really powerful machine with many processers to handle all the connections.
We project we will have about 5,000 Inserts per sec coming from 500,000 users.
What do you think or what has your previous experience been with handling many inserts and few reads for many users?
Thank you
Thank you in advance for any advice that is provided from by the Dev Shed Users.
I'm on a development team that has been having an ongoing discussion/argument about the best way to handle our users needs while in Europe.
We are developing a Purchase Order application in VB.net using MSSQL Server 2000. We have about 5 out of 10 users that take a six-week trip to Europe. While in Europe the users will need to use the application. However, there are some cities they visit where the network connection will be slim to none.
The ongoing argument is as follows:
-Should we create a server running SQL Server 2000 for them to take Europe and sync up the two databases when they return?
-Should we create a version of the application running MS Access?
-Should we create a version of the application running MySQL?
-Should we do something completely different that we haven't thought of?
-Also, I'm not sure if the following is a possible architecture, from what I've found online I haven't seen an architecture that runs both SQL Server and Access (hope this makes sense):
Build the VB.net application running a shell of the database in Access (locally) that temporarily houses the data and tracks the database transactions made while using the system. Then upon closing the application a ?module? would execute that would perform the transactions made by the user on SQL Server. Then we could dump the SQL Server Database to an Access database before they go to Europe, and run their changes on the SQL Server Database when they return. Users at home will not be making changes to the same data as those in Europe.
Again any help would be greatly appreciated.
HiI joined a project where 100,000 rows were added everyday. Now due toadditional customers the expectation is 2 million reocrds/day ie 10 GB worthof textfiles. We have to estimate the hard disk, memory, # of CPUs etc.Wewill have one yearworth of data in the db. Rest will be in tapes etc.We will be using WIN2000, SQL Server2000.- Any comparable server sizing willbe appreciated.1. Tohandle every day load, I thought that we will have a table for each day(pre created in the database )and have a view with union all selectingfromall these 365 tables. (This is the only way to partition in MSSQL Serverright?).2. The requirement is to populate datawarehouse tables with all the data.However there will be only inserts mostly but there can be updates too whichhappenned in the past 12 days.Hence we have to use the data from the last12 days and massage it etc and populate into datawarehouse tables.How can I do this so that I will have the datawarehouse tables with n-12days of data and I will alwys add the last 12 days data to it.Do you have any suggestions?Ragu
View 3 Replies View RelatedHi, I am planning on having an SSIS dedicated server in a new install of SQL 2005. We will be using MSDB to store the packages. But I have a question.
Since we will be using MSDB to store the packages, how should the setup be? Should SQL also be installed on the SSIS server? Or can we use the SQL server (seperated dedicated server) to store the files?
Since SQL Agent is installed with SQL Server, can we use our SQL Server to schedule the packages? Or if using the SQL Server to schedule the packages make the packages run on that server (instead of the SSIS server)?
Basically I am confused on what needs to be installed on the SSIS server (since we will be using MSDB storage) and where the packages should be scheduled (if scheduled on SQL but SSIS is installed on a different server, where will it process??).
Thanks.
i'm going nuts with SQL server notification thing. I have gone throigh this artical which tells how to set user http://www.codeproject.com/KB/database/SqlDependencyPermissions.aspx. This article show how to create new user and setup for sql server notification.But In my case user was alredy existing in database. which is very common senario in most cases. So i did following( check the SQL script below) but then i get this error
"A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)"
this my sql script
use [master]Go

Hi,
I was trying to extract data from the source server using OLEDB Source and SQL Server Destination when i encountered this error:
"Transaction (Process ID 135) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.".
What must be done so that even if the table being queried is locked, i wouldn't experience any deadlock?

Hello all,
I am running into an interesting scenario on my desktop. I'm running developer edition on Windows XP Professional (9.00.3042.00 SP2 Developer Edition). OS is autopatched via corporate policy and I saw some patches go in last week. This machine is also a hand-me-down so I don't have a clean install of the databases on the machine but I am local admin.
So, starting last week after a forced remote reboot (also a policy) I noticed a few of the databases didn't start back up. I chalked it up to the hard shutdown and went along my merry way. Friday however I know I shut my machine down nicely and this morning when I booted up, I was in the same state I was last Wenesday. 7 of the 18 databases on my machine came up with
FCB:pen: Operating system error 32(The process cannot access the file because it is being used by another process.) occurred while creating or opening file 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf'. Diagnose and correct the operating system error, and retry the operation.
and it also logs
FCB:pen failed: Could not open file C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf for file number 1. OS error: 32(The process cannot access the file because it is being used by another process.).
I've caught references to the auto close feature being a possible culprit, no dice as the databases in question are set to False. Recovery mode varies on the databases from Simple to Full. If I cycle the SQL Server service, whatever transient issue it was having with those files is gone.
As much as I'd love to disable the virus scanner, network security would not be amused. The data and log files appear to have the same permissions as unaffected database files. Nothing's set to read only or archive as I've caught on other forums as possible gremlins. I have sufficient disk space and the databases are set for unrestricted growth.
Any thoughts on what I could look at? If it was everything coming up in RECOVERY_PENDING it's make more sense to me than a hit or miss type of thing I'm experiencing now.
Dear list
Im designing a package that uses Microsofts preplog.exe to prepare web log files to be imported into SQL Server
What Im trying to do is convert this cmd that works into an execute process task
D:SSIS ProcessPrepweblogProcessLoad>preplog ex.log > out.log
the above dos cmd works 100%
However when I use the Execute Process Task I get this error
[Execute Process Task] Error: In Executing "D:SSIS ProcessPrepweblogProcessLoadpreplog.exe" "" at "D:SSIS ProcessPrepweblogProcessLoad", The process exit code was "-1" while the expected was "0".
There are two package varaibles
User::gsPreplogInput = ex.log
User::gsPreplogOutput = out.log
Here are the task properties
RequireFullFileName = True
Executable = D:SSIS ProcessPrepweblogProcessLoadpreplog.exe
Arguments =
WorkingDirectory = D:SSIS ProcessPrepweblogProcessLoad
StandardInputVariable = User::gsPreplogInput
StandardOutputVariable = User::gsPreplogOutput
StandardErrorVariable =
FailTaskIfReturnCodeIsNotSuccessValue = True
SuccessValue = 0
TimeOut = 0
thanks in advance

How do I use the execute process task? I am trying to unzip the file using the freeware PZUnzip.exe and I tried to place the entire command in a batch file and specified the working directory as the location of the batch file, but the task fails with the error:
SSIS package "IngramWeeklyPOS.dtsx" starting.
Error: 0xC0029151 at Unzip download file, Execute Process Task: In Executing "C:ETLPOSDataIngramWeeklyUnzip.bat" "" at "C:ETLPOSDataIngramWeekly", The process exit code was "1" while the expected was "0".
Task failed: Unzip download file
SSIS package "IngramWeeklyPOS.dtsx" finished: Success.
Then I tried to specify the exe directly in the Executable property and the agruments as the location of the zip file and the directory to unzip the files in, but this time it fails with the following message:
SSIS package "IngramWeeklyPOS.dtsx" starting.
Error: 0xC002F304 at Unzip download file, Execute Process Task: An error occurred with the following error message: "%1 is not a valid Win32 application".
Task failed: Unzip download file
SSIS package "IngramWeeklyPOS.dtsx" finished: Success.
The command in the batch file when run from the command line works perfectly and unzips the file, so there is absolutely no problem with the command, I believe it is just the set up of the variables on the execute process task editor under Process. Any input on resolving this will be much appreciated.
Thanks,

I am designing a utility which will keep two similar databases in sync. In other words, copying the new data from db1 to db2 and updating the old data from db1 to db2.
For this I am making use of the 'Tablediff' utility which when provided with server name, database, table info will generate .sql file which can be used to keep the target table in sync with the source table.
I am using the Execute Process Task and the process parameters I am providing are:
WorkingDirectory : C:Program Files (x86)Microsoft SQL Server90COM
Executable : C:SQL_bat_FilesSQL5TC_CTIcustomer.bat
The customer.bat file will have the following code:
tablediff -sourceserver "LV-SQL5" -sourcedatabase "TC_CTI" -sourcetable "CUSTOMER_1" -destinationserver "LV-SQL2" -destinationdatabase "TC_CTI" -destinationtable "CUSTOMER" -f "c:SQL_bat_Filessql5TC_CTIsql_filescustomer1"
the .sql file will be generated at: C:SQL_bat_Filessql5TC_CTIsql_filescustomer1.
The Problem:
The Execute Process Task is working fine, ie., the tables are being compared correctly and the .SQL file is being generated as desired. But the task as such is reporting faliure with the following error :
[Execute Process Task] Error: In Executing "C:SQL_bat_FilesSQL5TC_CTIpackage_occurrence.bat" "" at "C:Program Files (x86)Microsoft SQL Server90COM", The process exit code was "2" while the expected was "0". ]
Some of you may suggest to just set the ForceExecutionResult = Success (infact this is what I am doing now just to get the program working), but, this is not what I desire.
Can anyone help ?
I'm pulling data from Oracle db and load into MS-SQL 2008.For my data type checks during the data load process, what are options to ensure that the data being processed wouldn't fail. such that I can verify first in-hand with the target type of data and then if its valid format load it into destination table else mark it with error flag and push into errors table... All this at the row level.One way I can think of is to load into a staging table then get the source & destination table -column data types, compare them and proceed.
should I just try loading the data directly and if it fails try trouble shooting(which could be a difficult task as I wouldn't know what caused error...)
Hi Folks,
I am having this table locking issue that I need to start paying attention to as its getting more frequent.
The problem is that the data in the tables is live finance data that needs to be changed and viewed almost real time so what I have picked up so far is that using 'table Hints' may not be a good idea.
I have a guy at work telling me that introducing a data access layer is the only way to solve this, I am not convinced but havnt enough knowledge to back my own feeling up. (asp system not .net).
Thanks in advance

I would like to know where I can find a senior database architect. Someone who can develop
and implement the database and its stored procedures. I am looking for an experienced person.
It is a contract position, in San Franicisco. The pay is good. Could anyone help me?
I tried Dice, Monster and it seems all of you are working...
We will be creating a moderately high-volume OLTP database application that needs 24/7 availability. We are planning to offload OLAP processing to a second copy of the system. We will be using SQL Server 2005.
I originally planned to set the second server up with SQL Server 2005 mirroring to cover the 24/7 availability requirement, with the idea that we could also do OLAP reporting off of the mirrored copy of the database. But I've gotten some indications that a mirror database is offline and not available for querying. So I figured I would use transactional replication to keep the OLAP database current. Now I am wondering if I need to use mirroring at all, or if I should just use transactional replication on the entire database and swap to the replicated database if the production server crashes.
What is everyone's opinion?
Replication only, for both OLAP reporting and failover?
Mirroring to one database for failover, with replication to a another database for OLAP reporting?
Hi there,
My question is more "architectural" than technical.
One of our standard is to systematically enclose the code of our stored proc within a TRY/CATCH block.
What is your point of view?
Should a TRY/CATCH be included even for simple operations?
Are there any drawbacks?
Thanks!
EDIT: Thanks for your input.
I've implemented a solution with application, database and report server on seperate machines. The application is a web app and is Internet facing. What is the best method for executing reports on the RS server that are initiated from the web server? Using URL access requires a login or anonymous access neither of which are desired. Web services works but I loose access to the toolbar. Is there some other way to pull this off where I can let the public access reports and give them access to the toolbar?
Thanks.
In a situation where one may have a single master SQL Server that ultimately needs to communicate information back down to 1000's of downstream servers, what is the recommended architectural approach?
It doesn't feel right to have to add 1K-5K routes to the master SQL Server. Is there a way to have the dowstream servers "broadcast" their existence to the master, so that new servers can be added and updates can happen seamlessly? Does this fall into a pub-sub scenario or is there a better way? And, if so, how to ensure an open conversation (so that one server doesn't miss information that all the other servers received)? Should the master dynamically create routes or better to rely on an open conversation initiated by the downstream server?
Hi Everybody ,
Could Anybody please explain in detail about the Achitecture of Sql server reporting services?
1) What a Report processor in detail and what it does?
2) What is the exact work of Extensions?
3)What is SOAP and WMI?

Hi,
I'm trying to upload the ASPNETDB.MDF file to a hosting server via FTP, and everytime when it was uploaded half way(40% or 50%)
I would get an error message saying:
"550 ASPNETDB.MDF: The process cannot access the file because it is being used by another process"
and then the upload failed.
I'm using SQL Express. Does anybody know what's the cause?
Thanks a lot
Hi. When I try to start a package manually clicking the Start Debugging button I get this after a little while:
Cannot process request because the process (3880) has exited. (Microsoft.DataTransformationServices.VsIntegration)
How can I prevent this from happening? This happens every time I want to start the package and
every time the process id is different. Here it is 3880.

I have the following stored procedure:
INSERT INTO MyTable ( Value1, Value 2)
VALUES( @Value1, @Value2)

How do I put this sp in the DAL typed dataset, so I can get the Identity value in the Business Layer?
When having multiple files for log, do they get filled one after the other (like Oracle) or proportionately fill?
