Hi,
I read the following article related to "Federated Database Servers" But i am not getting what is this "Federated Database Servers", May be the language of this article i think little bit difficult. So, can anyone please explain me this.
Wht are thse servers and when, why and where we use these servers?????
http://msdn2.microsoft.com/en-us/library/aa213244(SQL.80).aspx
Thanks,
I'm trying to do some researh on the use of SQL's DPV. I'm looking for feedback from people who've actually done this production to know more about the design challenges and level of added administration required. Any information will be much appreciated. Thanks.

Hi Folks.
I am trying to understand federated servers. So far I have been able to link 2 servers, create a distributed view, and run a select and insert query against the view.
The next thing that I need to understand is how to deal with triggers and with identity columns (ie columns that have auto-increments).
Our application is using triggers on tables in several cases to keep track of create and update dates. So there is a trigger that automatically updates the datetime field on a table whenever that row gets updated or changed or created. This way the programmer doesn't need to remember to update those date time values. Now I understand that in the distributed view architecture the triggers on the underlying tables may not work. Can any one comment on this?
As well, I have a table which has the identity enabled, so it is incrementing a counter and creating a unique integer key value for each new record. How does this work when we move to a distributed architecture? How do I assure a unique key is generated in the distributed view architecture?
Thank you in advance.
Do you need a particular version of SQL Server, i.e. Enterprise, to set up Federated Databases?

I have an assignment: write a stored procedure with a parameter @location
this variable will in turn choose a stored procedure from a different server based on the value.
I never heard of federated db's before, or federated stored procedures, can anyone help with
this problem or give me clues or details? i am using SQL 2000, and i have access to multiple db's
Hello everyone.
I am trying to implement linked servers and I am having some trouble. The setup is as follows: I have two machines with the same SA login/pwd. BOTH machines have a database called: Federated_Bridge.
On machine 1: Federated_Bridge contains a table Fed_Entity_1
On machine 2: Federated_Bridge contains a table Fed_Entity_2
Machine 1, when I look it up in SQL Enterprise Manager it says: (local)
Machine 2, when I look it up in SQL Enterprise Manager it says: REALIBM2
When I expand those, I can see the databases folder and I can then see Federated_Bridge respectively.
On machine 1 (local) I am trying to create a linked server. I use the following SP call:
---------
use master
go
EXEC sp_addlinkedserver
@server = 'TEST3',
@srvproduct = 'SQLServer OLEDB Provider',
@provider = 'SQLOLEDB',
@datasrc = 'REALIBM2Federated_Bridge'
EXEC sp_addlinkedsrvlogin 'TEST3', 'false', 'sa', 'sa', 'mysapwd'
--------
The above queries seem to execute fine. Afterwards, when I check in Enterprise manager, I can see under linked servers TEST3 .. but no tables or views are showing.
When I run the following select query from query analyzer, I get an error message:
SELECT * FROM Test3.Federated_Bridge.dbo.Fed_Entity_2
SQL Server Does Not Exist Or Access Denied
Please help!!
Thanks.

i wanted to combine the data from two tables. these two tables belong to different servers: table1 is from sql server found in cerebrum station and table2 is from mysql server found in copernicus station. i have this code but the problem is i can only use this code if the two tables belong in the same database server.

How to backup database on the other servers in the LANS.
View 8 Replies View RelatedI am attempting to move a User Database from the Production Server to a Training Server. What is the best/most simplistic way for me to accomplish this task and place this copying action on a schedule of say "every saturday morning @ 7am"

Hello All,
I need some help with a web application we are running. Is it possible to have 2 seperate instances of SQL 2005 running and each one pointing to the same DB. We want to load balance our users on the different DB servers. They are performing read and write transactions.
Any suggestions.
Hi,
I've got two servers with sql 2005 express on, the first is a shared server at our isp, we rent one database from them. The other server is our own and we have full sa access.
Is there an easy way to copy the database from the shared server onto our own server. We're unable to use the backup.

I have a SSIS package which is used to update the OLAP database daily. It includes various processes from the initial dropping of the raw data source tables, rebuilding it, dropping of the OLAP datamart tables (dimension tables and fact tables), re-building it, updating the OLAP dimensions and finally updating the OLAP cubes. I wrote a series of the Sql scripts to perform the tasks except the updating of the OLAP dimensions and cubes, and assigned them to the SSIS package. Everything is working great and it was scheduled with the sql agent to execute at the early hour everyday. We have a single server enviroment for the "Production/Processing" i.e. Database engine, SSIS, SSAS, SSRS are all installed on a single server. By the way we are using Sql 2005.
Recently we split the "Production/Processing" enviroment into two seperated servers. We purchase another server "Production" server and use the existing server as the "Processing" server. I want to copy the success updated OLAP database from the current server "Processing" server to the new "Production" server. How to copy an OLAP database between servers?
Idealy, I believe that the following 5 processes should be assigned after the completion of the OLAP cubes updated at the "Processing" server:
Stop the SSAS at the "Production" server.........I know how to do this in SSIS
Re-name the existing OLAP database at the "Production" server.......not sure how to do this
Copy the newly updated OLAP database from "Processing" server to the "Production" server. If the copy process is succeed, drop the OLAP database that has just been re-named at the "Production" server. If the copy process is failed, re-named the OLAP database that has just been re-named back to the original name.....not sure how to do this. Should it be a Sql script?
Start the SSAS at the "Production" server........I know how to do this in SSIS

Hello,
I am working on an ASP.NET apllication which will work with sensitve data that needs stored as encrypted. The ASP.NET application and SQL Server 2005 will be hosted outside of our company.
My questions are:
When I create a database master key, a certificate and a symetric key to encrypt and decrypt my data, will I be able to use these (master key, cert and symetric key) in other databases (say my local development SQL Server 2005 instance)?
Is a managed hosting a better solution to have total control over the the keys in the database?
Is there a white paper or guidance document for security in hosted databases?Thanks

Apologies if this question has been asked before. I am about to upgrade a multiuser application based on Access97 and VB6 to C# and possibly SQL Server Express.
My customer does not want to use a server based database solution ie a single instance of SQL Server, but prefers to have a common networked dataset which is accessed via user's own individual database engines. This is because of restrictions on the installation of server based apps.
Does this scenario completely rule out the use of SQL Server Express?
Thanks

I have a report that was designed using SQL Reporting Services that sits on a SQL reporting server. It's nothing too exciting, it is essentially a three page application with legal jumbo on pages 2 and 3 and applicant data in fields on page 1.
We use rectangles to force page breaks to page 2 and to page 3.
When running the report on the report server, it shows and prints fine.
When running the report from the QA website internally, it shows and prints just fine.
When running the report from the production website from a machine internally, it shows and prints just fine.
When running the report from outside of the company network, the report is jacked. It obliterates large chunks of text, crams text together, and creates blank pages.
I need help in determining where I even begin with trouble shooting this!

Scenerio : To keep a very large system running optimally in a VM cluster, Take PR01 and make PR02, PR03, PR04. Distribute the 45 databases and 9T+ of disk across multiple VM guest.
Each PR## is a SQL Server 2012 Enterprise guest on a VM 5.1 cluster.
So instead of PR01 needed 16 core and 128g of memory, each one will have 4 core and 32g of memory. Making VM HA more manageable. (yes, DRS rules will apply). Also provides more HBA paths and distributes i/o over more physical disk on the SAN.
Instead of a connection string having to know PR01.dbo.UserDB01, PR02.dbo.UserDB03, ect the connection would be PRDB.dbo.UserDB01. That way if needed 1) UserDB can be moved to any of the PR## 2) new PR05, PR06 can be added as needed. The end user and processes are not allowed to touch system databases, no PR## will have a user DB called the same name.
There are seperate VM guests on other VM clusters and Citrix servers that need access to PRDB. As things expand and move around, none of the connection strings need to be changed.
I am looking into RadWare and modifing level 7 information, but that is iffy and $$$$$$.
Hi,On my laptop I am running Virtual Server 2005 with 2 x Windows 2003Servers. Both the VS can access the internet and shared files on thehost laptop. On the host laptop I have a SQL Server 2000 running.I have written a Windows Service to detect Application Errors and fireduplicates of events to the database, and this service sits on both VS.It does work as I have tested it on host. BUT everytime I makeapplication errors on the VS nothing is deposited into my database.Very frustrating!I have also tried to create a ODBC connection through the Data SourceAdministrator, and when I enter the login credentials for SQL I getconnection error messages.Any suggestions would be great!ThanksSun
View 3 Replies View RelatedHello,Being a bit of a SQL Server novice, need some advice with the followingsituation.Server A and Server B have SQLServer 2000 based databases. The vendorof the application/system has implemented their own replication processto ensure the 2 databases are in sync. However, there is no clusteringwith virtual IP addresses implemented. So to an external client/db, itis 2 identical databases with the same name on 2 distinct servers.We need to develop an application that will reside on a networkedserver C and with SQLServer 2000 as well. While most of the tables inthis database are self contained, around 10 tables will have to bemirror copies of the same tables from either Server A or Server B.Question, how do we implement subscription based replication on top ofa redundant database, when no clustering is implemented? So, inessence, when Server A is alive, the database on Server C willperiodically (or on change) replicate the 10 tables from Server A. WhenServer A is not alive, it needs to do same from server B. (When bothserver A and B are alive, it is acceptable to get data from either,since they are synchronized internally).Any alternate suggestions on achieving this functionality are welcometoo. If SQL Server 2005 has some capabilities that may address thisproblem, that is a consideration as well.Thanks
View 1 Replies View RelatedGreetings all,This should be an easy task, and Im sure it is, but as many times as I havetried, I cant seem to get this to work properly.We changed ISPs recently from a shared host to a co-located server, and ourformer host was nice enough to send us a backup of our old SQL2000 database(about 5MB).I went into Enterprise Manager, created an empty database with the same nameand used the Restore Backup tool successfully. I took a look at the db andsaw all the Tables and data intact.Next I wanted to re-create the DSN to match the old one so that I wouldnthave to fiddle with any of the old connection strings in my asp pages.Thats where the fun began. The old DSN was created by our host via an emailrequest and I never got a look at the actual creation process of that DSN.I created one on our colo server with the same name, but it would only passthe connection tests when I used the Windows User Authentication rather thanSQL Server Authentication. No big deal I figured, and just went ahead andset it up using the same DSN name.Next I tried the main.asp page to test the DSN and lo and behold I got theODBC connection errors. I tinkered with the connection strings a bit andmanaged to get a wide variety of connection errors and fine-tuned to thepoint that it said "Unable to login with user 'SERVER169/nacog'". At thispoint, I went into Enterprise manager and added 'nacog' to the User list andthe connection string no longer produced errors. (By the way, my connectionstring simply contains "DSN=YAVAPAICONNECT;")My next step was to actually execute a SELECT statement which produced thefollowing error:Microsoft OLE DB Provider for ODBC Drivers error '80040e09'[Microsoft][ODBC SQL Server Driver][SQL Server]SELECT permission denied onobject 'ADMINS', database 'YAVAPAICONNECT', owner 'dbo'./nacog/admin/main.asp, line 189Why was I not surprised?I went back to Enterpise Manager, saw the all the tables had 'dbo' as theowner, and tried to give 'nacog' all the permissions at the table level, butthe error persists.To preserve my sanity I stopped there, because I spun my wheels for hoursand days the last time this happened. and my eye has not stopped twitchingsince ;)I am quite sure that this has something to do with one or all of thefollowing:1) The way SQL2K was installed (it was installed by someone else)2) My creation of the db with the windows login, rather than SQL auth, priorto import3) My creation and handling of the DSNMy background is mainly in ASP programming, and I understand bits and piecesof this puzzle, but for the life of me I cannot piece this thing together.Can anyone help point me in the right direction or suggest a good tutorial?I would be very thankful to anyone who could help put me on the right track.Best Regards,Ben M.
View 1 Replies View RelatedHi,
We have a client who runs SQL Server 2000 queries on one database server and performance is approx. 4 seconds. If the database is backed up, no tables in the query or indexes on these tables are modified (we may run a small script that affects stored procedures, views, etc.) the query can run virtually forever.
The customer is runing a cluster and we are running a stand-alone. Although, the two environments that they run in and have these wildly different results in are the same.
The queries are not worth listing (join a couple of tables and views, select a few columns, put on a few conditions--nothing crazy).
Is this normal behavior for MS SQL Server?
I've personally seen where a database is backed up and query plans and performance are different from one server to another, but we are looking at extreme cases here. In fact, on the second server, the majority of the queries are faster and only a couple run very slowly.
Also, the query optimizer seems to be making poor decisions at this custoemer. For example, two tables will be cross joined (forming over 200 million records) and then table scans ensue. The process in some cases will take a 4 second query to 45 minutes.
To me none of this makes any sense. I've been working with SQL Server since 1997 and have not experienced any type of performance problems or variances of this magnitude. Although this is a 6GB database, SQL Server 7 ran on a terabyte without even blinking, so I wouldn't understand why this would have anything to do with it.
Also hampering our efforts is that we do not have easy access to this SQL Server database to get our hands on it and debug these issues.
Does anyone know of a way to examine these issues in a "system wide" manner to determine what the problems could be since the problems are not specific to the database (i.e. .bak file) but seem to be specific to the server?
They have also had database corruption (an index that wouldn't update) and had to roll back the database. Would that indicate that the MDF/LDF's are unstable? Is there a way to figure out if there is some type of MDF/LDF file structure corruption?
Thanks,
Henry.
Hi All,
I am facing a strange issue with accessing data from SQL server 2000. We are using SQL Server authentication for connecting to SQL Server 2000 and ADO .Net SQL client in the application. The problem here is, we have databases installed in one of the servers in some other office location that is in different state but on same domain. We do development from two locations that is one from Virtual Machines hosted on servers where Database Servers are located and on our local desktops in India.
Now when I developed a test client in Virtual Machines which will call a web service to get datasetof some data and show them in DataGrid. When I run the test client in debug mode from Visual Studio 2003, then I am getting data in the DataGrid. Even when I just run the exe from Virtual Machine still I am getting data.
But when I copy debug folder of the test client to the local desktop in India and when I run the Test client I am not getting any data loaded on to the DataGrid. I am getting an empty dataset when I am running from the local desktop.
Also I have converted the VS2003 project to VS2005 and when I run the application from Local Desktop then I am getting the data loaded fine. I could not understand what is the problem, what is the difference between accessing data from VS2003 and VS2005 using webservice.
Is this a firewall issue or I am missing any thing here. The webservice method I am calling to get data is actually returning dataset when I am calling this method directly from the browser also and even through application in virtual machine.
I am still not able to come to terms with this problem. This is severely affecting our deployment. Please help us resolve this problem. Please let me know if you need more information.
Thanks,
Venkatesh
can anyone tell me if they know of a way to automate the update process from development servers to live server, with little interference from an administrator
I have a development team that are constantly updating their databases along with their ASP code, and want to publish changes an a weekly basis. They have asked me for a way to take their new structures, tables, procedures etc, and copy them to the live servers, but NOT to interfere with existing customer data.
Funny I know – and I hate the idea btw :(
