  • How to achieve the following RTO & RPO with logshipping only using SQL Server?

    - by Jimmy Chandra
    Trying to come up with viable backup restore & logshipping solution for achieving the following: 15 minutes Recovery Point Objective (no more than 15 minutes data loss at any time) 5 minutes Recovery Time Objective (must be able to get the db up and running back by 5 minutes) Considering using logshipping only (which I think is kind of pushing it, but I want to know if anyone else know how to achieve this). Some other info for consideration: Using 40 Gbit / sec fiber channel between the primary and disaster recovery (DRC) sites The sites are about 600 km apart. At close of business, the amount of data generated is predicted to be about 150 MB/sec. Log backup is planned for every 5 min. Doing some rough calculation I came up w/ the following numbers: 40 Gbit / sec = 5 MB / sec @ 100% network efficiency. 5 MB / sec = 300 MB / min. @ 300 MB / min, the total amount of data that can be transfer considering the 5min RTO is about 1.5GB, but that will left no time for the actual backup and restore, so if we cut it down to 3min logshipping time, which equals to ~900 MB over 3 minutes at 100% network efficiency, that will left about 1 min backup time and 1 minute restore time. Currently don't have any information if the system being used is capable of restoring 900 MB in 1 min, but assume it can. for COB scenario... 150 MB/sec, and considering the 3 min logshipping time, which should equal to about 27 GB of data over 3 mins...??? I think this is where the SLA will break... since there is no way to transfer 27 GB of data over a 40Gbit/sec line in 3 min. Can I get someone else opinion? I am thinking database mirroring might be a better answer for this...

  • Can Resource Governor for SQL Server 2008 be scripted?

    - by blueberryfields
    I'm looking for a method to, in real-time, automatically, adjust Resource Governor settings. Here's an example: Imagine that I have 10 applications, each hitting a different database on the same database machine. For normal operations, they do not hit the database very hard, so I might want each one to have 10% CPU power reserved. Occasionally, though, one or two of them might spike, and run an operation which could really use the extra power to run faster. I'd like to be able to adjust to compensate (say, reducing the non-spiking apps to 3%, and splitting the difference between the spiking apps). This is a kind of poor man's method of trying to dynamically adjust resource allocation and priorities. Scripts (or something script-like) is preferred, since the requirement is for meta-level adjustments to be possible in real-time, also.

  • User cannot access a system DSN on Windows Server 2008

    - by Ra Osolage
    We run our SQL Server services using a low privileged domain account. That account is NOT a local admin on the OS. Only access I give the user account is assigned during install of SQL: full control over its mount points and then everything else is granted by the SQL Server 2005/2008 installer. I need to create a linked server in SQL Server 2008 to an ODBC data source. So I remoted into the computer using my domain account, which is part of a group that DOES have local admin privs to the OS. I created a system DSN and configured it to connect to another SQL Server. The DSN works perfectly when I test it. However, when I try to create the linked server, I get an error. It appears to me that the DSN is invisible to the domain account that SQL Server is running as. It seems that this problem is only happening to me on Windows 2008 servers. Does anybody know whether there's anything that you need to do after creating a DSN to make it visible for other users to access?

  • What's the best way to store sort order in SQL?

    - by Duracell
    The guys at the top want sort order to be customizable in our app. So I have a table that effectively defines the data type. What is the best way to store our sort order. If I just created a new column called 'Order' or something, every time I updated the order of one row I imagine I would have to update the order of every row to ensure posterity. Is there a better way to do it?

  • Copy one db diagram from one db to another on different servers? (Same db)

    - by sah302
    I used the copy database wizard to copy my database from our test server to our production server, the database copied everything fine except for the diagram. Okay no problem, first I make sure the target database on production has the support objects created to use database diagraming. Then I select to import data from the other database and chose the dbo.sysdiagrams.Go through with the rest of the import data wizard, but then I get the following error: Validating (Error) Messages Error 0xc0202049: Data Flow Task: Failure inserting into the read-only column "diagram_id". (SQL Server Import and Export Wizard) Error 0xc0202045: Data Flow Task: Column metadata validation failed. (SQL Server Import and Export Wizard) Error 0xc004706b: Data Flow Task: "component "Destination - sysdiagrams" (31)" failed validation and returned validation status "VS_ISBROKEN". (SQL Server Import and Export Wizard) Error 0xc004700c: Data Flow Task: One or more component failed validation. (SQL Server Import and Export Wizard) Error 0xc0024107: Data Flow Task: There were errors during task validation. (SQL Server Import and Export Wizard) So apparently it didn't like that. What's the problem? I am pretty beginner in SQL Server and only do stuff via the GUI usually so am not sure what to do at this point. The databases are the same, but on different servers. Thanks!

  • How can Windows defragmentation tools cause internal fragmentation in SQL Server?

    - by Martin
    I was just reading this article where the author talks about the file system fragmentation that can be caused by growing database files. There was one bit that I didn't quite follow. What about Windows defragmentation tools? Although you can use a Windows defragmentation tool to defragment your database files, these tools simply move chunks of files around to get them contiguous. This moving of chunks of files can cause internal fragmentation that you might not be able to resolve easily. Is the author saying here that the disc defragmenter makes no attempt to put the chunks of files in the correct sequence or have I misunderstood? If he is saying that then is this a limitation of all disc defragmenter utilities - even commercial ones?

  • SQL Server architecture - they want to move my database to new instance...Why?

    - by O'MALLEY
    Our current production database environment contains about 10 similarily managed databases. Our agency has just purchased and is installing new blade chasses and wants to move my database to a new instance (leaving the other 9 on another). This decision is being driven by one of our IT staff, not a DBA. I am a project manager, not a DBA but I know enough to not necesarrily have a good feeling about this decision and I am urging our IT department to make a sound decision based on what is best for the database. Our IT department has stated that it is not good to have all our eggs in one basket, and has also stated that my database contains "regulatory data" so it should be on its own instance. A couple of truths: - None of the databases on the current instance are OLTP databases nor are any of them data warehouses - My database currently has joins/views to a couple of the other databases in the production environment So my questions are as follows: Am I wrong to disregard a statement about eggs in baskets? (hello, this is why we have maintenance plans/disaster recovery plans). I'll mention that other databases also have regulatory data too. What types of questions do I need to ask to determine if this is a sound decicion? (A DBA friend mentioned that if the service level agreement of said database does not radically differ from the others then why do they want to do this?) I have done some research on linked servers. What arguments should I bring forth about the fact that I have views setup that rely on data from other DBs currently?

  • Why when trying to restore a SQL DB from backup, it keeps referring to backup's original location an

    - by rm
    I've done a full DB backup to C:\Backups\MyDb.bak Then I've setup a job to incrementally back the DB up every day to that same location. Then I've moved the backup files to X:\Backups\, changing the target directory in backup job Now that I try to restore the database from backup, it keeps trying to refer to C:\Backups\MyDb.bak, but that file is no longer there. How do I fix the issue w/o having to move the backup files back to C:\Backups?

  • Does the password get sent in the clear when connecting to Sql-Server?

    - by Scott Chamberlain
    I was asked this today and I honestly did not know the answer. If you connect using a connection string without sspi to a server is there any way a 3rd party can intercept on the wire the password used to log in? "Data Source=MyServer;Initial Catalog=MyDatabase;User Id=sa;Password=CanThisBeSniffed;" I am not asking about MiTM attacks just someone listing on the same computer or on the same hub on the network with wireshark or something similar running. I fired up wireshark myself and did not see it in plain text but it could be a simple obfuscation or proper encryption, I just wanted to know which.

  • How can I remove unallocated space from a SQL Server database?

    - by Dynamo
    I have a database that was recently shrunk and when I run sp_spaceused I see that it has 500MB of unallocated space. I'm trying to keep this database to a certain size (do to MSDE size restrictions for my desktop users) and I'm not sure if the unallocated space affects the overall database size. Is there a way to remove this unallocated space from the database?

    It seems my HTC Magic running Android 1.5 (Cupcake) has three home screens I can switch between. I can't find any kind of option to add additional home screens (the "home screen" menu only lets me add Widgets, Shortcuts and Folders or change the Wallpaper). Is there any way I can add more?

  • Firefox keyboard shortcuts to menu items / add-on functions

    - by Cel
    At the moment I'm using context menus a lot to access commands in Firefox, but I would like to replace this repetitive clicking and searching with keyboard shortcuts for the common tasks that I perform. How to assign keys to add-on functionality? E.g. I use Close Other Tabs from Tab Mix Plus a lot - but I could not find any add-on that allows me to create a key combination for it e.g. Ctrl Alt Shift F4? My search did yield Key config, but this extension does not allow mapping to add-on functions I thought Menu Editor might be relevant, as you can change menus with it, and re-arrange even add-on items A rather demanding solution here, which seems to require re-compiling some jar files Customizing menu shortcuts in Firefox

  • How can I set up a database (SQL?) for literary annotations?

    - by Jon
    I'm a literature student and I'd like to be able to annotate literary texts (originally stored in HTML or as text files) on a word-by-word or line-by-line basis. I hear databases like mySQL or SQLite would be good ways to do this sort of thing, but I don't really know where to start. I'm comfortable with the linux command-line, and have done some HTML/CSS work in the past, so I feel unintimidated by databases and things...I just don't know what to start doing.

  • Which default Database Systems come installed in Microsoft VS2010 Express?

    - by Tonygts
    Appreciate all advice 0n the following questions Which database systems (Ms SQL 2008, MS SQL Compact, or others) comes installed with VS2010 Express edition. SQL Server 2008 R2 Express is free, can we install and integrate with VS2010 Express? How to uninstall those database already come installed? I have installed VS2010 express on Windows 7; just VS2010 components (VB, C#, C++ and Web Developer) and without installing any other things like SQL Express. In the Console Panel-Program & Features' window, the installed list is shown below: Microsoft SQL Server 2008 Setup Support File Microsoft SQL Server 2008 Browser Microsoft SQL Server VSS Writer Microsoft SQL Server Database Publishing Wizard 1.4 Microsoft ASP.NET MVC2 - VWD Express 2010 Tools Microsoft SQL Server 2008 Management Objects Microsoft SQL Server Compact 3.5 SP2 ENU Microsoft SQL Server System CLR Types Microsoft Silverlight 3 SDK Microsoft ASP.NET MVC 2 Microsoft Visual Studio 2010 ADO.NET Entity Framework Tools Visual Studio 2010 Tools doe SQL Server Compact 3.5 SP2 ENU Web Deployment Tool Microsoft Visual Web Developer 2010 Express - ENU Microsoft Visual C++ 2010 Express - ENU Microsoft Visual C# 2010 Express - ENU Microsoft Visual Visual Basic 2010 Express - ENU Microsoft SQL Server 2008 As you can see, Microsoft SQL Server 2008 (last line) and near the top, Microsoft SQL Server Compact 3.5 SP2 ENU and many of their related SQL components such as Microsoft SQL Server 2008 R2 Management Objects are also installed. These are actually installed by installing VS2010 Express, but I have no idea how to use them or verify their valid existence from VS2010. Also, do I have to uninstall them before I install SQL Server 2008 R2, which is the latest version I believe? And what tool is needed to manage and create data source and tables?

  • Add site to trusted sites through GPO

    - by Matt Bear
    I need to add a site to trusted sites on all computers in my domain. I can do it with the "site to zone assignment list", however when I do, it locks trusted sites on the client computer "this setting is managed by your administrator". What I need is a way to add the site, make it persistant, and not affects the users ability to add trusted sites of thier own. (It's a development enviroment, sites are created and tested regularly, they need that ability.)

  • How do you create a SQL query in Excel 2007 with a dynamic date range?

    - by Jordan
    I am trying to create a reporting spreadsheet that can print reports for a given time period. The query below works, but when I try to use a "?" parameter in place of the date, I get an error after selecting a cell containing my date. If I use single quotes ('?') I get a conversion from string to date/time failure, if I don't (?) I get a syntax error near @p1. Eventually I will need either a start and end date or a formula adding a month or shift to the starting date/time to filter the data down to important information. The query was built in Microsoft Query. SELECT FloatTable.DateAndTime, TagTable.TagName FROM master.dbo.FloatTable FloatTable, master.dbo.TagTable TagTable WHERE FloatTable.TagIndex = TagTable.TagIndex AND ((FloatTable.DateAndTime={ts '2012-06-01 00:00:00'})) Any assistance would be much appreciated. Thanks in advance.

  • Issue with corrupt 1tb volume: can we rescue SQL databases?

    - by Barrie Ashmore
    We have an instance where some how a 1tb volume has become corrupted. There are Event ID 55 errors in the system event viewer. When running chkdsk, it gets to 47% verifying indexes and returns to the command prompt. If we are unable to rescue the data on the drive then we have a full backup of the databases from some time ago. The logfiles of which are on a different volume which is intact. Would it be viable to restore the databases and somehow replay the log files? I have seen articles about replaying logfiles from a logfile backup (.trn), however we have the actual logfiles (.ldf) Any help would be appreciated.

  • ip route add HOMEIP via SERVERIP disconnects me from ssh

    - by Arya
    I want to use a vpn connection on my Debian server but I get disconnected from ssh if I connect to the vpn. I thought by using the "ip route add" I can prevent getting disconnected from my server and it will continue to use the main connection for communication between my computer and the server, and the vpn for communication with other ips. This is the command I use ip route add PUBLICHOMEIP via PUBLICSERVERIP But I get disconnected after the "ip route add" command too. Am I making a mistake anywhere?

  • Making Thunderbird auto-add SMTP identities whenever I reply

    - by 0xC0000022L
    How can I teach Thunderbird to automatically add an SMTP identity whenever I reply to an email directed to <whatever>@<mydomain>? So if an SMTP is configured for <mydomain> but no identity exists for <whatever>@<mydomain>, how can I make Thunderbird dynamically recognize this and add it. Currently I have to manually add the identity every single time, but I would prefer it to to be added ad-hoc. As long as Thunderbird was configured to know about the SMTP serving <mydomain> this should be trivial, but I couldn't find an option. An add-on or something like a catch-all/wildcard identity would also do as long as it doesn't require manually setting up a new identity every time.
