My company has valuable data being constantly logged to a database 24/7. Actually, the data logs to two separate database systems in case one goes down for whatever reason such as power failure, routine maintenance, glitch, whatever. These two systems are housed at different physical locations.
We are planning to set up a third database system which polls the other two every minute. It compiles and mantains a deduped, clean, and complete collection of data from the other two database systems. If one of the first two systems goes down or misses a row, the third will automatically get the data from the other system. If this deduped database system goes down, we can rebuild the data from the other two.
Does this seem like the right route to take or is there a simpler or safer route available?
Hey Guys,We have a merge replication on 2 MsSQL servers and wondering if its possible to allow the 2 connection strings in our application?So if SQL Server 1 doesnt responed, then the other one will take over.we currently have this in our global.asax:Public Shared dbConnString as String = "Server=xxxx;Initial Catalog=xxxx;User Id=xxxx;Password=xxxx;" So is it possible to change this to look up the first server and then connect to a second server if needed?Thank you for any advice at all.
What is the best way to insure 100% availability of our SQL databases? Should we use clustering, mirrored servers (Vinca or Double-take)? What are other organizations doing about this?
After some feedback from some of you who might have done something similar:
We are going to be having 3 SQL servers (running SQL Std licence). 2 Are live 1 is a hot swap in the event that we have a total loss of either of the SQL boxes. Basically what I am wanting to do, is have the hot swap being updated periodically so that the databases are being replicated on this box, so that if the live one fell over, we could very quickly get the hot swap into take over.
Can anyone offer any perspectives on the best method of attack for this?
Hey guys...i've got a problem wif my stored procedures...in which my page keep repeating the same data...so to counter this problem i use SELECT DISTINCT instead of just SELECT..but the problem is when i change SELECT into SELECT DISTINCT...the page will not be display,page error....for your information my stored procures was auto generate from some security sofware...so can guys help me out with my code...

I have a table that I want to have a precalulcate length on a character fieldand group and sum up. Thought I could do this by creating a view with a groupby clause that includes the sum function. Unfortunately, the compilercomplains with:A clustered index cannot be created on the view 'MyView' because the indexkey includes columns which are not in the GROUP BY clause.Wish I could verbalize the problem a little better, but the following pareddown example should serve as a demonstration:SET ANSI_WARNINGS ONSET ANSI_PADDING ONSET ANSI_NULLS ONSET ARITHABORT ONSET CONCAT_NULL_YIELDS_NULL ONSET QUOTED_IDENTIFIER ONSET NUMERIC_ROUNDABORT OFFGOCREATE TABLE myTable(myID INT NOT NULL,RecNum INT NOT NULL,TestString VARCHAR(80) NOT NULL)GOINSERT INTO myTable VALUES(1, 1, 'a')INSERT INTO myTable VALUES(1, 2, 'ab')INSERT INTO myTable VALUES(2, 2, 'abc')GOCREATE VIEW dbo.MyView WITH SCHEMABINDING ASSELECTmyID = myID,slen = SUM(LEN(TestString)),recn = COUNT_BIG(*)FROM dbo.myTableGROUP BY myIDGOCREATE UNIQUE CLUSTERED INDEX IX_MyView ON MyView(myID, slen)-- A clustered index cannot be created on the view 'MyView' because-- the index key includes columns which are not in the GROUP BY clause.GODROP VIEW MyViewGODROP TABLE myTableGOThanks,Chris Rathman
Today a vendor bluntly stated that VMWare provides the same failover and redundancy for SQL that would render "AlwaysOn" high availability unnecessary.
Essentially that VMWare would detect a problem and failover and have .9999 uptime .
We replicate a SQL2000 database (DataBaseA) to a SQL2000 database (DataBaseB) by using the Restore function and hasn't change its logical name but only the physical data path and file name. It is running fine for a year. We use the same way to migrate the DataBaseB to a new SQL2005 server with the Restore function and the daily operation is running perfect. However, when we do the Backup of DatabaseB in the SQL2005, it just prompt the error message
System.Data.SqlClient.SqlError: The backup of full-text catalog 'DataBaseA' is not permitted because it is not online. Check errorlog file for the reason that full-text catalog became offline and bring it online. Or BACKUP can be performed by using the FILEGROUP or FILE clauses to restrict the selection to include only online data. (Microsoft.SqlServer.Smo)
Please note we left the DataBaseA in the old SQL2000 server.
Please help on how we can delete the Full-text catalog from DatabaseB so we can do a backup

Greetings, I have just arrived back into the country (NZ) and back into ASP.NET. I am having trouble with the following:An attempt to attach an auto-named database for file (file location).../Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share. It has only begun since i decided i wanted to use IIS, I realise VWD comes with its own localhost, but since it is only temporary, i wanted a permanent shortcut on my desktop to link to my intranet page. Anyone have any ideas why i am getting the above error? have searched many places on the internet and not getting any closer. Cheers ~ J
I have a problem when i restore my .DAT_BAK file. I am getting error like "The backup set holds a backup of a database other than existing database. Restore Database is terminating abnormally".
I tried by using
RESTORE DATABASE <DATABASENAME> FROM DISK = 'D:DATAMYTEST.DAT_BAK' WITH MOVE 'VZAI_DATA' TO D:PROGRAM FILES..MSSQLTEST.MDF', MOVE 'VZAI_LOG' TO D:PROGRAM FILES..MSSQLTEST.LDF', REPLACE
And also i tried like
RESTORE DATABASE <DATABASENAME> FROM DISK = 'D:DATAMYTEST.DAT_BAK'
WITH REPLACE
When i use like this,
RESTORE FILELISTONLY FROM DISK = 'D:DATAMYTEST.DAT_BAK'. I am able to get the output as LogicalName, PhysicalName, Type, FileGroupName, Size, etc.

I recently added a new user to my database. Now I want to delete that user, but I keep getting the error above. What do I need to do to delete my recently added user?
We have a SQL database that uses Active Directory with Windows Authentication. Can users that are members of the Active Directory group that has read/write access to the SQL database create ODBC connections to access the database directly and update the data? They dont have individual logins on the server. They are only members of the Active Directory group that has a login?
I had to to relocate the database log file and I issued an Alter database command but by mistake I put a space in the file name as below. The space is at the beginning file name. Now I am unable get the database loaded to SQL Server. The database has 2 replications configured, so deleting and re-attaching the database means the replication needs to be re-configured. Is there an alternative way to issue a command to update the database FILENAME ? Not sure if this can be edited in master database (sys files).
ALTER DATABASE [User_DB] MODIFY FILE (NAME = User_DB_log, FILENAME = 'I:SQLLogs User_DB_log.ldf') GO

I downloaded and ran AdventureWorks.msi into my SQL Server Management Studio Express (SSMSE) one year ago.But I did not know how to attach it to my SSMSE then. Last week, I deleted it from the "Add or Remove" of Control Panel and I downloaded the new AdventureWork.msi and installed it my SSMSE. Today, I tried to use the Database Explorer of VB 2005 Express for the first Stored Procedure programming. I clicked on AdventureWorks.mdf and I got the following error: One or more files do not match the primary of the database. If you are attempting to attach a database, retry the operation with the correct files. If this is an existing database, the file may be corrupt and should be restored from a backup. Cannot open user default database. Login failed. Login failed for user 'CENADe1enxshc'. Log file 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataAdventureWorks_Data_log.ldf' does not match the primary file. It may be from a different database of the log may have been rebuilt previously. Please help and advise me how to correct this problem.
I have installed 2 SQL Server 2005 Express sample databases from 2 books, ASPnet 2.0 and ADOnet 2.0. The ASPNETDB.MDF was shown in App_Data and Database Explorer, but not in the SQL Server Management Studio Express. The AdoStepBy Step database created by a ConfigDB.exe was displayed in the Management Studio, but not in the App_Data, or Database Explorer.
Is this the way SQL Server 2005 runs the 2005 databases for SQL Server 2005 Express only? Or also in SQL Server 2005?
I am setting up SQL audit on sql servers in my environment based on requirement. I want to create database specifications ASAP database created. I tried DDL trigger but Audit doesn't support triggers. So I created audit specifications on model database. the only problem with this is every specification created on new database with same name.database specification name includes newly created database name or other methods to create database specifications on newly created databases.
I am new to SSIS. I have been struggling with this for the past one week. I have a weird task. I need to import several tables from one database to a different server with a new database name. We need to do this at the end of every year. The main problem here is that the number of tables varies every year. You may not have all the tables as last year or may have more tables. So I need to create a dynamic task that takes care of this every year without changing the package.
I have performed the following tasks **
1. Create a new dynamic database. ( I have used Execute SQL Task to do this) 2. Copy all the table structures ( I have used Execute SQL Task to do this)
3. Import Data. This is the main problem. I was trying to create a dynamic connection string with variables as suggested in several forums but I finally came to know that this cannot be done if the table structures are different as the metadata cannot be refreshed at runtime.
4. The final step to create a process to validate the data (the count from each table for both source and destination. I think this can be done with Sql task.
What is the best method to do this? My DBA does not like “Transfer SQL Objects Task” or “transfer Database Task”. I would like to create this as a dynamic process.
I have a medical records system, SoapWare v4.90, that uses MSDE (SQL2000) databases. Due to the 2gb limitation, I am trying to migrate over to SQL 2005 (Standard or Express) which I have heard works fine. The SoapWare has a datamanager that allows me to log in to the MSDE instance, detach the SoapWare databases from msde (as well as do backups, etc) which I can confirm are detached.
Then I log back into a SQL2005 database instance using the datamanager and try to attach the database. This is what their pictured instructions demonstrate. However, I get the following error:
Database 'sw_charts' cannot be upgraded because it is read-only or has read-only files. Make the database or files writeable, and rerun recovery.
Of course, some of the entries will be read only, since doctors have to sign off the charts and are not allowed to subsequently change them. But I should still be able to switch over to sql 2005?!?!?!?
Or... is there a way to attach the databases to SQLExpress manually?
Dear All, i have a question abt winCE 4.2 and SQL server CE. i am using VB.net of Visual Studio 2005 My platform is using a PDA with winCE 4.2 and SQL server CE. The Host program is using dbf files on desktop side.
I got a problem of how to sync / read the sql CE data from a windows application.
so, i wanna ask,
1. any method to access the data from winCE data by windows application? or can i convert the sdf file to windows readable files? or any others?
2. Can i use a MDB to sync with SQL server CE? can i synchronize the mobile device which has a SQL Server CE database with the Access database on the desktop?
last question, 3. is that windows CE .net 4.2 not support pocket access (cdb) anymore?
Hi all (newbie @ asp.net)(oldie @ ASP 3)What is the purpose of using an attached MDF database files in the App_Data folder on a web site as to importing it into the SQL server directly or creating it on the SQL server. Does a mdf database attached file purely use the SQL server as a connection interface.Is it something similiar to DSN(ODBC) Connections for ms access databases.
Using SQL Server Express 2005, I have two databases. AppDB - The main application database.GeoDB - A somewhat static ZIP code / states / other geographic stuff databaseI need to have some foreign key columns in tables in AppDB reference columns in the GeoDB database tables. Eventually other application database besides AppDB will be doing the same thing in our infrastructure. After googling and reading for days, here is what I think I know:You cannot create foreign keys that reference tables in another database in SQL Server.You cannot create foreign keys that reference columns in a view, and you definitely cannot make an index on a view that has base tables in another database.You can create a trigger that references tables in another database, but this can be flaky? (nested/recursive trigger problem).SQLServer 2005 supports multiple schemas within the same database. Maybe I should logically separate my databases this way? Seems like it would be a tough solution to manage since I already have some databases live in production that will eventually use this 'static' GeoDB. Also, seems like it wouldn't be as portable as keeping the GeoDB info in its own database, but maybe I'm being too software engineer-ish here - afraid of low cohesion, high coupling.I will greatly appreciate any advice I can get, or any more options I am missing. Thanks,Adam Nofsingerucnmedia.com
