• Best way to replicate / mirror 100s of databases in SQL 2005

  - by mrwayne

  Hi, I currently host around 400-500 SQL 2005 databases of varying sizes (1-10 gig) each. I am aware of most of the different methods available and the general pros/cons of mirroring, log shipping, replication and clustering, but i am not aware of how well they tend to perform when its employed at the size i have specified (400-500 unique databases). Does anyone have any good advice on what is likely the best method for having the ability to fail over to another server with this sort of setup? Fail over does not need to be immediate, i'm just looking for something better than taking backups every day and moving them to storage. I'm preferably looking for something that would also makes it easy to manage the databases in bulk (as opposed to one at a time). Thanks for your input!

• SQL SERVER – Weekly Series – Memory Lane – #038

  - by Pinal Dave

  Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 CASE Statement in ORDER BY Clause – ORDER BY using Variable This article is as per request from the Application Development Team Leader of my company. His team encountered code where the application was preparing string for ORDER BY clause of the SELECT statement. Application was passing this string as variable to Stored Procedure (SP) and SP was using EXEC to execute the SQL string. This is not good for performance as Stored Procedure has to recompile every time due to EXEC. sp_executesql can do the same task but still not the best performance. SSMS – View/Send Query Results to Text/Grid/Files Results to Text – CTRL + T Results to Grid – CTRL + D Results to File – CTRL + SHIFT + F 2008 Introduction to SPARSE Columns Part 2 I wrote about Introduction to SPARSE Columns Part 1. Let us understand the concept of the SPARSE column in more detail. I suggest you read the first part before continuing reading this article. All SPARSE columns are stored as one XML column in the database. Let us see some of the advantage and disadvantage of SPARSE column. Deferred Name Resolution How come when table name is incorrect SP can be created successfully but when an incorrect column is used SP cannot be created? 2009 Backup Timeline and Understanding of Database Restore Process in Full Recovery Model In general, databases backup in full recovery mode is taken in three different kinds of database files. Full Database Backup Differential Database Backup Log Backup Restore Sequence and Understanding NORECOVERY and RECOVERY While doing RESTORE Operation if you restoring database files, always use NORECOVER option as that will keep the database in a state where more backup file are restored. This will also keep database offline also to prevent any changes, which can create itegrity issues. Once all backup file is restored run RESTORE command with a RECOVERY option to get database online and operational. Four Different Ways to Find Recovery Model for Database Perhaps, the best thing about technical domain is that most of the things can be executed in more than one ways. It is always useful to know about the various methods of performing a single task. Two Methods to Retrieve List of Primary Keys and Foreign Keys of Database When Information Schema is used, we will not be able to discern between primary key and foreign key; we will have both the keys together. In the case of sys schema, we can query the data in our preferred way and can join this table to another table, which can retrieve additional data from the same. Get Last Running Query Based on SPID PID is returns sessions ID of the current user process. The acronym SPID comes from the name of its earlier version, Server Process ID. 2010 SELECT * FROM dual – Dual Equivalent Dual is a table that is created by Oracle together with data dictionary. It consists of exactly one column named “dummy”, and one record. The value of that record is X. You can check the content of the DUAL table using the following syntax. SELECT * FROM dual Identifying Statistics Used by Query Someone asked this question in my training class of query optimization and performance tuning.  “Can I know which statistics were used by my query?” 2011 SQL SERVER – Interview Questions and Answers – Frequently Asked Questions – Day 14 of 31 What are the basic functions for master, msdb, model, tempdb and resource databases?

• OSX 10.6 Give Apache2 read&write access to mounted windows share

  - by JohEngstrom

  On Mac OS X Snow Leopard I'm trying to give the apache2 user _www full rights to a mounted hidden windows server share. I've used Connect to Server with smb://servername/share$ and saved the username/password in the keychain. The domain username used for the mount got full rights to the share on the windows server. It all works this far. I can browse and edit the files in the share from the Mac. However I can't find a way to give the apache2 user _www rights to write to the mounted share. I have a perl script that is supposed to create a file in the mounted folder but only get permission denied. I've tried all kinds of chmod and chown but it doesn't change the permissions of the share. Does anyone know how this can be done please?

  I have no experience in setting up postfix, and thought virtualmin minght do the legwork for me. Appears not. When I try to send mail to the domain (either [email protected] [email protected] or [email protected]) I get the following message returned This is the mail system at host dedq239.localdomain. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.

  Hi, I'm trying to figure out where the settings and options of an application(Adobe Acrobt Pro) are saved. This is to modify the settings without opening the application and going through the menu options. I'm trying to change the resolution of TIF settings. I have looked in the program file acrobat folder and the douments and settings but haven't found it. I also looked through the registry entrees just to make sure but didn't see anything relevant. Anyone have any ideas? Thanks

• Find and hide file extension

  - by Daveo

  I am trying to find all files that have the same filename (excluding the file extension) that occur 3 times. I also need the full path to the file. What I have currently is #get file without extension alias lse="ls -1R | sed -e 's/\.[a-zA-Z]*$//'" #print out the current dir and get files occuring 3 times lse | sed "s;^;`pwd`/;" | sort | uniq -c | grep " 3 " This runs howver pwd prints the folder I ran the command from not the path to the file. So I tried find find . -type f | sed "s#^.#$(pwd)#" | sort | uniq -c This runs but includes the file extension. When I try to add sed -e 's/\.[a-zA-Z]*$//'" I get errors as I am not sure how to combine the two sed commands and I cannot seem to pipe a second time to sed? so what I am trying to do is find . -type f | sed "s#^.#$(pwd)#" | sed -e 's/\.[a-zA-Z]*$//'"| sort | uniq -c | grep " 3 " but this does not run.

• How can I re-encode H.264 video with minimal quality loss?

  - by SofaKng

  I have a lot of MPEG-TS files (.TS container but H.264 video) and playback is fine except that when you skip forward/backward or fast forward it's very sluggish and gets pixelated, etc. I've been trying to do research and I'm guessing that they were encoding with very few reference blocks (ie. it's a capture from a DVB-S satellite stream). When I re-encode them with Handbrake (.MP4 container) they play very, very good and seeking in the video is instant, etc, etc. Is it possible to transcode/re-encode my MPEG-TS files with minimal quality loss? If so, what is my best bet? They are each about 2 Mbps (ie. 2 GB per hour) but I don't want to re-encode them if "minimal quality loss" requires 10+ GB per file. I'm hoping to keep the video are the same size. Can anybody give me any advice?

• Website Upgrade - Avoid Downtime

  - by nolan.sipos

  I have been requested to investigate how I can reduce the downtime of our website upgrades. We maintain a DNN site with both public facing pages and member only pages. The member only pages are directly linked to our core application database while the public pages are not. Our current process is to redirect website users as soon as the upgrade process begins, which includes Backup of the Prod DB Update Prod DB Update Executables (Application) Upgrade Website Application (If this requires an update) Install Dependencies Upgrade sub systems like communication engine and payment broker Update various configuration files Perform testing of systems Restart all services Allow access to site This process can take from 2 to 8 hours depending on upgrade required, scripts to be run, size of database and number or portals. My initial thoughts are to restrict users to read only pages and any update pages would be unavailable. Could anyone please offer suggestions as to the best practices for what I would think to be a common problem so that we can reduce this down time and if we need infrastructure changes, I can put this to our technical department.

• Fastest light-weight image viewer over forwarded x11 session (linux)

  - by Matthew

  I have a slow network connection over which I'm forwarding x11 over ssh. I want to view images on the remote host (Ubuntu) quickly and efficiently. I'm looking for an image viewer that will take into account the image viewer window's resolution and downsize the image before sending it over the network, instead of sending the full size image. The images I want to view will be around 5MB and I only need to be able to browse through tiny thumbnails of the images to identify the image I'm looking for. It is not necessary to be able to see more than one image at a time. Highest speed over slow network connection is the priority. Thanks! Matthew EDIT: It's possible that the way x11 forwarding works, only the image at the display resolution will be transferred anyway. If that's true, please confirm and the question still stands for which image viewer will be the fastest over a slow connection

• How can I tell if my Amazon Windows instance was an SQL Server AMI?

  - by Aligma

  I want to purchase some reserved instances, because I have several instances already created and running 24 hours a day. When I go to purchase a Windows instance, I can see 3 options, Windows Windows with SQL Server Standard Windows with SQL server Web I don't know which of these was used to create the original instance. Is there a way I can find out? My assumptions: the instance type is is important because as far as I understand, the way to purchase a reserved instance is to first have a running instance, and then purchase a matching reserved instance. The reserved instance is not itself a new machine, but a kind of contract between you and Amazon to pay for an instance for 1 or 3 years, at a discounted rate. The contracted, reserved instance will "offset" one matching running instance where they have the same size and platform. Please feel free to correct me if these assumptions are incorrect.

• Finding out if a FLAC or WAVPACK audio file is NOT originally encoded from a lossy source

  - by cornel

  Is there a way of checking that the so-called FLAC or WAVPACK audio file was originally encoded from a lossless source (WAV, CDA, APE, etc.) instead of a lossy source (MP3, AAC, ATRAC, etc.)? Say I have a lossy MP3 audio file (5.17Mb, 87% compressed from its original, source unknown). I then encode it to another lossless format, say FLAC or WAVPACK. The size increases (23.14Mb, 39% compressed from its original, source MP3)! ID tags, etc, remain the same and there's no way of checking the integrity of its origin. How do I go about doing that?

• RSync over SSH - permission denied even though the user is in the root group

  - by Bastien974

  I have a need to copy files between servers through the web. I'm using RSYNC over ssh to do so. The problem is, I need to be able to transfer files, no matter where the files is. I created a user rsync and : usermod -G root -a rsync to give him the right to read/write anywhere on both servers. During the transfer, I see this error: rsync: mkstemp "/root/.myFile.RDr2HY" failed: Permission denied (13) I don't understand what's happening. edit: I just found out that the destination folder didn't have the write access for the root group. How would I give 100% access to this rsync user ? If I change its uid to 0, rsync stop working.

• Want to Run OS Commands From WLST?

  - by Bala Kothandaraman

  If you spend a lot of time with WLST in the interactive mode, I am sure you have opened another command prompt/shell to check something at the OS file system level. If you wonder whether can execute an OS command from within WLST prompt, the answer is "Yes". This is very convenient similar to how you can execute OS commands from within "Vi" editor. In fact this feature is not from WLST but from underlying Jython. There is "os" module in Jython that provides a unified interface to a number of operating system functions. There is "system" function in the "os" module that can take a OS command as a string input and returns either "0" or "1" depends on whether the command was successful or failed. So this feature can also be used with scripting mode where the return code can be verified for further processing in the script. For eg. os.system(r'dir c:\bea') can list the contents of the bea folder under c drive. Notice the use of the preceding 'r' for escaping the entire string.

• OpenGL - Stack overflow if I do, Stack underflow if I don't!

  - by Wayne Werner

  Hi, I'm in a multimedia class in college, and we're "learning" OpenGL as part of the class. I'm trying to figure out how the OpenGL camera vs. modelview works, and so I found this example. I'm trying to port the example to Python using the OpenGL bindings - it starts up OpenGL much faster, so for testing purposes it's a lot nicer - but I keep running into a stack overflow error with the glPushMatrix in this code: def cube(): for x in xrange(10): glPushMatrix() glTranslated(-positionx[x + 1] * 10, 0, -positionz[x + 1] * 10); #translate the cube glutSolidCube(2); #draw the cube glPopMatrix(); According to this reference, that happens when the matrix stack is full. So I thought, "well, if it's full, let me just pop the matrix off the top of the stack, and there will be room". I modified the code to: def cube(): glPopMatrix() for x in xrange(10): glPushMatrix() glTranslated(-positionx[x + 1] * 10, 0, -positionz[x + 1] * 10); #translate the cube glutSolidCube(2); #draw the cube glPopMatrix(); And now I get a buffer underflow error - which apparently happens when the stack has only one matrix. So am I just waaay off base in my understanding? Or is there some way to increase the matrix stack size? Also, if anyone has some good (online) references (examples, etc.) for understanding how the camera/model matrices work together, I would sincerely appreciate them! Thanks!

• Internal only DNS?

  - by ethrbunny

  We are running a research project with hundreds (becoming thousands) of remote hosts. Each host is running OpenVPN so we can find them regardless of what their 'assigned' IP is. We have been using DynDNS to manage this but we're running into some issues with them ( API is weak/nonexistent, size constraints, etc). Im looking into setting up a internal-only domain (EG "our.stuff" so a host would be "site1.our.stuff" or "site3.net4.our.stuff") that I can configure with the info from the OpenVPN server. Since we'd have to point our internal DNS to this machine it would have to be able to route/cache requests for 'external' machines as well. I've been trying to read about 'internal DNS', 'private', 'non-routeable' but I'm not having much success. Summary: need info on internal, caching DNS server. Something with open-source would be ideal. If not, I can script out changes to .conf, etc.

• Properties!Details (run-time length)

  - by user33666

  When you take clips and turn them into computer playable files, whether .TS or .MOV or .MPG, .MP4, .VOB, etc., do you as the producer actually manually write into some field in a "Details" section of your video editor what the video length is, so that it can be read by the eventual user's video player? Or is this activity performed automatically by the video editor? I'm asking because: when a mouse is passed over a file line item in Windows 7 Shell (Windows Explorer) a little box is displayed where the mouse meets the file line item and provides simple name and size properties, one of which (if it's a media file) is run length. How does that figure get there into the file (later to be read be Windows or OS X)? Thanks for any info.

• How to sort by file's modified date on IIS web server in Windows 7?

  - by ????

  Apache has this built in since 1996 which is 17 years ago... for Microsoft's IIS Web server which is available on Windows 7, is there a way to make it be able to sort the file listing by file modification dates? For example, show the file listing with the label "Date", "Filename", and clicking it will sort the files by that attribute. The only info I could find is: http://technet.microsoft.com/en-us/library/cc732762(v=ws.10).aspx cd %windir%\system32\inetsrv appcmd set config /section:directoryBrowse /showFlags:Time|Size|Extension|Date|LongDate|None but it doesn't work.

• Black screen on Ubuntu 12.04

  - by user1648371

  I've just upgraded to Ubuntu 12.04 and I'm experiencing some problems. The first thing I noticed is that when I click the Workspace switcher all I get is a black screen (I can guess where the different workspaces are located and clicked on them, not a practical solution though). In addition when I lock the screen or suspend the laptop (a Vaio VPCEB4M1E) I get a shifted screen (I see the right most vertical stripe on the left size of the monitor and nothing about all the rest, to put it clearly I can see the gear that allows me to turn the pc off, etc, but not much more..) when I go to the additional driver menu I see the "ATI/AMD proprietary FGLRX graphics driver" are installed and the post-release update version is available. I don't know if the problem is driver related, so before doing anything I'd like to get some suggestions from you guys. Thanks you!

• Document-oriented vs Column-oriented database fit

  - by user1007922

  I have a data-intensive application that desperately needs a database make-over. The general data model: There are records with RIDs, grouped together by group IDs (GID). The records have arbitrary data fields, (maybe 5-15) with a few of them mandatory and the rest optional, and thus sparse. The general use model: There are LOTS and LOTS of Writes. Millions to Billions of records are stored. Very often, they are associated with new GIDs, but sometimes, they are associated with existing GIDs. There aren't as many reads, but when they happen, they need to be pretty fast or at least constant speed regardless of the database size. And when the reads happen, it will need to retrieve all the records/RIDs with a certain GID. I don't have a need to search by the record field values. Primarily, I will need to query by the GID and maybe RID. What database implementation should I use? I did some initial research between document-oriented and column-oriented databases and it seems the document-oriented ones are a good fit, model-wise. I could store all the records together under the same document key using the GID. But I don't really have any use for their ability to search the document contents itself. I like the simplicity and scalability of column-oriented databases like Cassandra, but how should I model my data in this paradigm for optimal performance? Should my key be the GID and should I create a column for each record/RID? (there maybe thousands or hundreds of thousands of records in a group/GID). Or should my key be the RID and ensure each row has a column for the GID value? What results in faster writes and reads under this model?
