  • SQLAuthority News – Presenting at Virtual Tech Days TechEd Pre-Con – February 9, 2011

    - by pinaldave
    I will be presenting on following subject on Virtual Tech Days TechEd Pre-Con – February 9, 2011. Auditing Made Easy: Change Tracking and Change Data Capture Date and Time: February 9, 2011 11:45am-12:45pm Location: Online In this fast paced demo oriented session we will go over few of concept which are related to real life problem at customers. We often see developers and DBA looking for details like who has dropped the table, who has last modified any object as well what was actually modified. SQL Server 2008 has all the answers. It has various new methods for Auditing where not only you can know details about what was changed as well know who changed it as well. In addition to that we can capture way more details configuring Auditing. We can also work prevent changes if proper policy management is configured. If you have ever attended my session on this subject earlier, this is going to absolutely new session and very much demo oriented. There is going to be quiz at the end of the session and I promise that if you attend the session, you will get all the answers correct.

  • Structuring database for multi-object "activity" and "following" functionalities

    - by romaninsh
    I am working on a web application which operate with different types of objects such as user, profiles, pages etc. All objects have unique object_id. When objects interact it may produce "activity", such as user posting on the page or profile. Activity may be related to multiple objects through their object_id. Users may also follow "objects" and they need to be able to see stream of relevant activity. Could you provide me with some data structure suggestions which would be efficient and scalable? My goal is to show activity limited to the objects which user is following I am not limited by relational databases. Update As I'm getting advices on ORM and how index things, I'd like to again, stress my question. According to my current design model the database structure looks like this: As you can see - it's quite easy to implement database like that. Activity and Follower tables do contain much larger amount of records than the upper level but it's tolerable. But when it comes for me to create a "timeline" table, it becomes a nightmare. For every user I need to reference all the object activities which he follows. In terms of records it easily gets out of control. Please suggest me how to change this structure to avoid timeline creation and also be abel to quickly retrieve activity for any given user. Thanks.

  • ADDS: 1 - Introducing and designing

It is the foundation stone on which all other products (Exchange, update services, office communicator, the system center family, etc) rely on to get their information. And that is just looking at it from an infrastructure perspective. A well designed and implemented Active Directory implementation makes life for IT personnel and user alike a lot easier. Centralised management and the abilities opened up  by having it in place are ample.  But what is Active Directory Domain Services? We can look at ADDS as a centralised directory containing all objects your infrastructure runs on in one way or another. Since it is a Microsoft product you'll obviously not be seeing linux or mac clients listed in here (exceptions exist) but in general we can say it contains everything your company has in place in one form or another.  The domain name services. The domain naming service (or DNS for short) is a service which translates IP address (the identifiers for each computer in your domain) into readable and easy to understand names. This service is a prequisite for ADDA to work and having wrong record in a DNS server will make any ADDS service fail. Generally speaking a DNS service will be run on the same server as the ADDS service but it is worth wile to remember that this is not necessary. You could, for example, run your DNS services on a linux box (which would need special preparing to host an ADDS integrated DNS zone) and run the ADDS service of another box… Where to start? If the aim is to put in place a first time implementation of ADDS in your enterprise there are plenty of things to consider depending on what you are going to do in the long run. Great care has to be taken when first designing and implementing as having it set up wrong will cause a headache down the line. It is for that reason that I like to start building from the bottom up and start with a generic installation of ADDS (which will still differ for every client) and make it adaptable for future services which can hook in to the existing environment. Adapting existing environments is out of scope for this document (and series) although it is possible to take the pointers and change your existing environment to run in a smoother manor. Take great care when changing things as one small slip of the hand can give you a forest wide failure… Whenever starting with an ADDS deployment I ask the client the following questions:  What are your long term plans and goals?  How flexible do you want it? Are you currently linux heavy and want to keep this or can we go for an all Microsoft design? Those three questions should give some sort of indicator what direction can be taken and if the client has thought about some things themselves :).  The technical side of things  What is next to consider is what kind of infrastructure is already in place. For these series I'll keep it simple and introduce some general concepts without going in to depth on integrating ADDS with other DNS services.  Building from the ground up means we need to consider our layers on which our infrastructure will rely. In my view that goes as follows:  Network (WAN/LAN links and physical sites DNS Namespacing All in one domain or split up in different domains/forests? Security (both for ADDS and physical sites) The network side of things  Looking at how the network is currently set up can potentially teach us a large deal about the client. Do they have multiple physical site? What network speeds exist between these sites, etc… Depending on this information we will design our site links (which controls replication) in future stages. DNS Namespacing Maybe the single most intresting thing to know is what the domain will be named (ADDS will need a DNS domain with the same name) and where this will be hosted. Note that active directory can be set up with a singe name (aka contoso instead of contoso.com) but it is highly recommended to never do this. If you do end up with a domain like that for some reason there will be a lot of services that are going to give you good grief in the future (exchange being one of them). So one of the best practises would be always to use a double name (contoso.com or contoso.lan for example). Internal namespace A single namespace is just what it sounds like. You have a DNS domain which is different internally from what the client has as an external namespace. f.e. contoso.com as an external name (out on the internet) and contoso.lan on the internal network. his setup is has its advantages in that you have more obscurity from the internet in the DNS side of this but it will require additional work to publish services to the web. External namespace Quite like the internal namespace only here you do not differ the internal namespace of the company from what is known on the internet. In this implementation you would host your own DNS servers for the external domain inside the network. Or in other words, any external computer doing a DNS lookup would contact your internal DNS server for the resolution. Generally speaking this set up is a bad idea from the security side of things. Split DNS Whilst using an external namespace design is fairly easy it involves a lot of security risks. Opening up you ADDS DSN servers for lookups exposes your entire network to the internet and should be avoided at any cost. And that is where the "split DNS" design comes in. In this setup up would still have the same namespace internally and externally but you would be using different DNS servers for lookups on the external network who have no records of your internal resources unless you explicitly publish them. All in one or not? In determining your active directory design you can look at the following possibilities:  Single forest, Single domain Single forest, multiple domains Multiple forests, multiple domains I've listed the possibilities for design in increasing order of administrative magnitude. Microsoft recommends trying to use a single forest, single domain in as much situations as possible. It is, however, always possible that you require your services to be seperated from your users in a resource forest with trusts set up between the different forests. To start out I would go with the single forest design to avoid complexity unless there are strict requirements to have multiple forests. Security What kind of security is required on the domain and does this reflect the physical security on the sites? Not every client can afford to have a domain controller in a secluded server room on every site and it is exactly for that reason that Microsoft introduced the RODC (read only domain controller). A RODC is a domain controller that has been limited in functionality, in essence it will only cache the data you explicitly tell it to cache and in the case of a DC compromise (it being stolen) only a limited number of accounts will need to be affected. Th- Th- Th- That’s all folks! Well at least for now! In future editions of this series we’ll be walking through the different task that need to be done and the thought which needs to be put in to it. But for all editions we’ll be going from the concept of running a single forest, single domain with a split DNS setup… See you next time!

  • How to Transpose Rows and Columns in Excel 2013

    - by Lori Kaufman
    You’ve setup your worksheet with all your row and column headings and you’ve entered all your data. Then, you discover that it would look better if the rows were the columns and the columns were the rows. How do you accomplish this easily? There is an easy way to convert your rows to columns and vice versa using the Transpose feature in Excel. We’ll show you how. Select the cells containing the headings and data you want to transpose. Click Copy or press Ctrl + C. Click in a blank cell on the spreadsheet. This cell will be the top, left corner of the new table of data. Click the down arrow on the Paste button and select Paste Special from the drop-down menu. On the Paste Special dialog box, select the Transpose check box so there is a check mark in the box and click OK. The rows become the columns and the columns become the rows. The original set of data still exists. You can select those cells and delete the headings and data, if desired. Isn’t that a lot easier and faster than retyping all your data?

  • Efficient solution for multiplayer space partioning?

    - by DevilWithin
    This question is a little tricky, but I will try to make it clear, Lets say I am building an online game, not in a mmo scale, but gladly supporting as many players as possible, in a authoritative server approach, and I want really big worlds with lots of AI simulated enemies. I am aware of a few strategies to save server's CPU by subdividing the space and not processing what doesn't need processing. I 've already split the world by regions, that will require loading times and small transitions, which i think is important to mantain the quality of gameplay when playing locally (alone or even with a couple of friends) because the players won't normally be in more than one or two regions. But even a region can become pretty big, and have a lot of NPC simulating at a time, how do I handle this without screwing the player's experience? Approaches like one server per region and alike are not in the table. I am mainly looking for data structures to hold hordes of enemies, and even peaceful NPC. To finalize the question, please note that vehicles exist, therefore its considerably fast to travel within a region, influencing the "when" to cull areas. Sorry for the confusing question, thanks

    since I will be doing an internship for which i need to use Windows software, I have decided to ruin my day trying to remove my Ubuntu 12.04, install Win XP SP3 (since the DualBoot theme from ubuntu suggests to first install Windows and then Ubuntu, for problems with the bootloader if you do it the other way around) and then reinstall Ubuntu 12.04 since I would like to keep using it as my primary operating system, using WinXP exclusively for the internship. Other than that, I would like to have a partition for the data, which can be used by both Ubuntu and Windows. So now, I have used the disk utility run from an ubuntu-live cd to format my drive with Master Boot Record (being conscious of the fact that this way I will lose all my data, which I have saved on an external drive before, and that my Ubuntu won't work anymore afterwards), creating partitions for Windows (NTFS), personal data (FAT, since as far as I know both Ubuntu and Windows can deal with this), a Swap partition for Linux, and one partition for Ubuntu (ext4); trying to install Win XP from cd gives me a blue screen, which stops the setup and telling me to remove all recently installed drives and to run CHKDSK. So I thought, that maybe Windows doesn't like pre-partitioned drives for its installation and thus I need to re-format my hard drive in order to have a completely "new" drive, which I can then, during the Windows-installation, partition in order to create the partitions I need. Trying to do this, though, the disk-utility run from the live-CD gives me this warning: Error creating partition table: helper exited with exit code 1: In part_create_partition_table: device_file=/dev/sda, scheme=0 got it got disk committed to disk BLKRRPART ioctl failed for /dev/sda: Device or resource busy I do not understand why it tells me that the hard-drive is busy, because, as stated above, I am doing all this from a live-CD. Thus, my questions are: How can I resolve the error given by the disk utility? Does it make sense to use four partitions in the way mentioned above? And if not so, which partitions should I create? Can I, theoretically, partition my drive from an Ubuntu live-cd in order to create the partitions I want and to install first Windows and then Ubuntu? Thanks for any help, David

  • displaying multi-section html documents - best practices

    - by ecpepper
    I work at a research organization and we publish a lot of large-ish documents, usually organized in sections. What I want to know is how best to present these multi-section documents on our website. Presently, what I do is load the entire document as a single page, with each section as its own div. Then I show and hide divs as needed via a table of contents and "next" and "prev" buttons. The advantages to this are mainly: 1) that you can move between sections very quickly, 2) it produces consistent analytics (when a page is loaded, I know a report is being read). The disadvantages, however, are real: Readers can't take advantage of browser back/forward buttons to move between sections. It's complicated to create direct links to individual sections (I can do it with javascript but it's not easy for other people to grab and share). For long reports, you have to wait for the full report to load before you can move around (and that can include hordes of images and charts). Do other people have thoughts on better ways to organize this? Here's an example of the current system: http://massbudget.org/825

  • Windows Azure Database (SQL Azure) Development Tip

    - by BuckWoody
    When you create something in the cloud, it's real, and you're charged for it. There are free offerings, and you even get free resources with your Microsoft Developer Network (MSDN) subscription, but there are limits within those. Creating a 1 GB database - even with nothing in it - is a 1 GB Database. If you create it, drop it, and create it again 2 minutes later, that's 2 GB of space you've used for the month. Wait - how do I develop in this kind of situation? With Windows Azure, you can simply install the free Software Development Kit (SDK) and develop your entire application for free - you need never even log in to Windows Azure to code. Once you're done, you simply deploy the app and you start making money from the application as you're paying for it. Windows Azure Databases (The Artist Formerly Known As SQL Azure) is a bit different. It's not emulated in the SDK - because it doesn't have to be. It's just SQL Server, with some differences in feature set. To develop in this environment, you can use SQL Server, any edition. Be aware of the feature differences, of course, but just develop away - even in the free "Express" or LocalDB flavors - and then right-click in SQL Server Management Studio to script objects. Script the database, but change the "Advanced" selection to the Engine Type of "SQL Azure". Bing. Although most all T-SQL ports directly, one thing to keep in mind is that you need a Clustered Index on every table. Often the Primary Key (PK) is a good choice for that.

  • Representation of data in application versus database

    - by user1815201
    I'm going to make an application that will be given data to put in a database. The data will for the most part be the same, but the way it is formatted will vary a lot (could be in anything from text files to .xls to .doc). I'm not a very experienced developer, but I can see some potential issues and I want to minimize them. First off I have decided to use the DAO pattern, so that I can easily support new file formats or file suddenly formatted in different ways. What I really wonder about though, is how I should manage the data itself within my application. I'm thinking that the database DAO should have models representing each table of the database with the same relations between them, to make the uploading process easy. But should the filesystem DAO's have to use the same models? I can imaging that when the database changes, the change will suddenly propagate throughout the entire system, all DAOs and models alike. And that is obviously a bad thing. I'm a little bit tired and out of time. Will update with what ever questions you have. Thanks!

  • IPs on home network

    - by windchime
    I have a Linksys router and a Belkin wireless router at home. The Linksys router is connected to cable modem and two computers, as well as to the Belkin wireless router. A 3rd computer is connected to the Belkin router through Wifi. The IP addresses of the computers connected to Linksys are 192.168.1.101 and 192.168.1.102. The IP address of the Linksys router on LAN is 192.168.1.1. The IP address of the Belkin wireless router is 192.168.2.1(based on the 3rd computer's routing table) and the IP address of the 3rd computer is 192.168.2.5. If I ping 192.168.1.101 from 192.168.2.5, all are well. However, if I ping 192.168.2.5 from 192.168.1.101, Destination Host Unreachable. Why?

  • Database Server Hardware components (order of importance), CPU speed VS CPU cache vs RAM vs DISK

    - by nulltorpedo
    I am new to database world and would like to know what are crucial hardware specs when it comes to database performance. I have searched the internet and found this so far (In order of decreasing importance): 1) Hard Disk: Get an SSD basically (much more IOPS than spinners) 2) Memory: Get as much as you can afford 3) CPU: For the same $ spent, prefer larger cache size over speed. Are these findings sensible? EDIT: I would like to focus on CPU speed VS CPU cache size. EDIT2: The database is used to store some combination of ints and int arrays with few text fields. There are a lot of Select queries looking for existing entries. If entry is not found, then insert it. I would say most of processing would be trying to find a match across a table with 200 columns and 20k rows. The insert statements are very few. EDIT3: Also, we have a lot of views (basically select queries).

  • maildir in Windows for IMAP

    - by User1
    I'm interested in accessing my IMAP accounts offline. I found that maildirs are a simple way to make it work. I found that [offlineimap] takes care of almost everything in making the IMAP-maildir sync happen. Then, I can open the account in Mutt or Wanderlust client. One major problem, maildirs use colons in their filenames. Windows doesn't allow colons. I tried mount -f -s -b -o managed "d:/tmp/mail" "/home/of/mail" in Cygwin, but doing an echo test > /home/of/mail/test:file didn't work I'm thinking about ext2fs, but I need an ext2 partition somewhere. Can I make a file into a partition somehow? I don't want to start modifying my hard drive's partition table. Besides, does anyone know if ext2fs will support colons in filenames?

  • Linux policy routing - packets not coming back

    - by Bugsik
    i am trying to set up policy routing on my home server. My network looks like this: Host routed VPN gateway Internet link through VPN 192.168.0.35/24 ---> 192.168.0.5/24 ---> 192.168.0.1 DSL router 10.200.2.235/22 .... .... 10.200.0.1 VPN server The traffic from 192.168.0.32/27 should be and is routed through VPN. I wanted to define some routing policies to route some traffic from 192.168.0.5 through VPN as well - for start - from user with uid 2000. Policy routing is done using iptables mark target and ip rule fwmark. The problem: When connecting using user 2000 from 192.168.0.5 tcpdump shows outgoing packets, but nothing comes back. Traffic from 192.168.0.35 works fine (here I am not using fwmark but src policy).

  • SQL SERVER – Introduction to PERCENT_RANK() – Analytic Functions Introduced in SQL Server 2012

    - by pinaldave
    SQL Server 2012 introduces new analytical functions PERCENT_RANK(). This function returns relative standing of a value within a query result set or partition. It will be very difficult to explain this in words so I’d like to attempt to explain its function through a brief example. Instead of creating a new table, I will be using the AdventureWorks sample database as most developers use that for experiment purposes. Now let’s have fun following query: USE AdventureWorks GO SELECT SalesOrderID, OrderQty, RANK() OVER(ORDER BY SalesOrderID) Rnk, PERCENT_RANK() OVER(ORDER BY SalesOrderID) AS PctDist FROM Sales.SalesOrderDetail WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY PctDist DESC GO The above query will give us the following result: Now let us understand the resultset. You will notice that I have also included the RANK() function along with this query. The reason to include RANK() function was as this query is infect uses RANK function and find the relative standing of the query. The formula to find PERCENT_RANK() is as following: PERCENT_RANK() = (RANK() – 1) / (Total Rows – 1) If you want to read more about this function read here. Now let us attempt the same example with PARTITION BY clause USE AdventureWorks GO SELECT SalesOrderID, OrderQty, ProductID, RANK() OVER(PARTITION BY SalesOrderID ORDER BY ProductID ) Rnk, PERCENT_RANK() OVER(PARTITION BY SalesOrderID ORDER BY ProductID ) AS PctDist FROM Sales.SalesOrderDetail s WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY PctDist DESC GO Now you will notice that the same logic is followed in follow result set. I have now quick question to you – how many of you know the logic/formula of PERCENT_RANK() before this blog post?

  • Optimizing PHP<>MySQL performance

    - by BarsMonster
    I am trying to optimize my PHP<MySQL on this test script: <? for($i=0;$i<100;$i++)//Itterations count $res.= var_dump(loadRow("select body_ru from articles where id>$i*50 limit 100")); print_r($res); ?> I have APC, and article table have an index on id. Also, all these queries are hitting query cache, so sole MySQL performance if great. But when I am using ab -c 10 -t 10 to bench this scipt, I am getting: 100 itterations: ~100req/sec (~10'000 MySQL queries per second) 5 itteration: ~200req/sec 1 itteration: ~380req/sec 0 itteration: ~580req/sec I've tried to disable persistent connections in PHP - it made it slower a bit. So, how can I make it work faster, provided that MySQL is not limiting performance here?

  • Routing only some local IPs through VPN on dd-wrt

    - by bo-inge-ostberg
    Much similar to this entry: http://serverfault.com/questions/94283/using-dd-wrt-to-connect-to-vpn-and-forward-all-traffic-of-certain-devices-through , I have set up my router with dd-wrt + OpenVPN to connect to a VPN. This works fine, and all traffic from behind the router goes through the VPN. How do I route(?) traffic in the router so that only certain IPs from the LAN will go through the VPN, while the others take the "normal" route? Is it also possible to allow traffic from certain local IPs to go ONLY through the VPN, making it impossible for them to use the regular internet connection if the VPN is down? I know this question was answered in the post I linked to, but that just doesn't seem to work for me. The routing table and rules change, but traffic still just goes through the VPN.

  • Increment numbers in page headers in Microsoft Word

    - by Imray
    In Microsoft Word, I am laying out a process in steps. Each page pretty much is a new step that begins with a header like: 3. Drive the body to a secure location I would like the numbers to automatically increment, particularly if later on I decide to add a new step somewhere in the middle. Does anyone know how I can achieve that in the simplest way? I already have a working Table of Contents and I'd prefer not doing something that would mess with that, if possible to avoid.

  • Light-weight, free, database query tool for Windows?

    - by NoCatharsis
    My question is very similar to the one here except pertaining to a Windows tool. I am also referencing this table and what I found here with a Google search. However, I have no idea which tool would best meet my (very basic) purposes. I am currently using Excel with a basic ODBC connection string to query my database at work. However, Excel is pretty memory-heavy and a basic query tends to throw my computer into a 30 second stall-a-thon. Is there a free tool out there that is light-weight and can serve the same purpose when provided an ODBC connection and a SQL query? Also would prefer that it easily copies over to a spreadsheet as needed.

  • quick look at: dm_db_index_physical_stats

    - by fatherjack
    A quick look at the key data from this dmv that can help a DBA keep databases performing well and systems online as the users need them. When the dynamic management views relating to index statistics became available in SQL Server 2005 there was much hype about how they can help a DBA keep their servers running in better health than ever before. This particular view gives an insight into the physical health of the indexes present in a database. Whether they are use or unused, complete or missing some columns is irrelevant, this is simply the physical stats of all indexes; disabled indexes are ignored however. In it’s simplest form this dmv can be executed as:   The results from executing this contain a record for every index in every database but some of the columns will be NULL. The first parameter is there so that you can specify which database you want to gather index details on, rather than scan every database. Simply specifying DB_ID() in place of the first NULL achieves this. In order to avoid the NULLS, or more accurately, in order to choose when to have the NULLS you need to specify a value for the last parameter. It takes one of 4 values – DEFAULT, ‘SAMPLED’, ‘LIMITED’ or ‘DETAILED’. If you execute the dmv with each of these values you can see some interesting details in the times taken to complete each step. DECLARE @Start DATETIME DECLARE @First DATETIME DECLARE @Second DATETIME DECLARE @Third DATETIME DECLARE @Finish DATETIME SET @Start = GETDATE() SELECT * FROM [sys].[dm_db_index_physical_stats](DB_ID(), NULL, NULL, NULL, DEFAULT) AS ddips SET @First = GETDATE() SELECT * FROM [sys].[dm_db_index_physical_stats](DB_ID(), NULL, NULL, NULL, 'SAMPLED') AS ddips SET @Second = GETDATE() SELECT * FROM [sys].[dm_db_index_physical_stats](DB_ID(), NULL, NULL, NULL, 'LIMITED') AS ddips SET @Third = GETDATE() SELECT * FROM [sys].[dm_db_index_physical_stats](DB_ID(), NULL, NULL, NULL, 'DETAILED') AS ddips SET @Finish = GETDATE() SELECT DATEDIFF(ms, @Start, @First) AS [DEFAULT] , DATEDIFF(ms, @First, @Second) AS [SAMPLED] , DATEDIFF(ms, @Second, @Third) AS [LIMITED] , DATEDIFF(ms, @Third, @Finish) AS [DETAILED] Running this code will give you 4 result sets; DEFAULT will have 12 columns full of data and then NULLS in the remainder. SAMPLED will have 21 columns full of data. LIMITED will have 12 columns of data and the NULLS in the remainder. DETAILED will have 21 columns full of data. So, from this we can deduce that the DEFAULT value (the same one that is also applied when you query the view using a NULL parameter) is the same as using LIMITED. Viewing the final result set has some details that are worth noting: Running queries against this view takes significantly longer when using the SAMPLED and DETAILED values in the last parameter. The duration of the query is directly related to the size of the database you are working in so be careful running this on big databases unless you have tried it on a test server first. Let’s look at the data we get back with the DEFAULT value first of all and then progress to the extra information later. We know that the first parameter that we supply has to be a database id and for the purposes of this blog we will be providing that value with the DB_ID function. We could just as easily put a fixed value in there or a function such as DB_ID (‘AnyDatabaseName’). The first columns we get back are database_id and object_id. These are pretty explanatory and we can wrap those in some code to make things a little easier to read: SELECT DB_NAME([ddips].[database_id]) AS [DatabaseName] , OBJECT_NAME([ddips].[object_id]) AS [TableName] … FROM [sys].[dm_db_index_physical_stats](DB_ID(), NULL, NULL, NULL, NULL) AS ddips  gives us   SELECT DB_NAME([ddips].[database_id]) AS [DatabaseName] , OBJECT_NAME([ddips].[object_id]) AS [TableName], [i].[name] AS [IndexName] , ….. FROM [sys].[dm_db_index_physical_stats](DB_ID(), NULL, NULL, NULL, NULL) AS ddips INNER JOIN [sys].[indexes] AS i ON [ddips].[index_id] = [i].[index_id] AND [ddips].[object_id] = [i].[object_id]     These handily tie in with the next parameters in the query on the dmv. If you specify an object_id and an index_id in these then you get results limited to either the table or the specific index. Once again we can place a  function in here to make it easier to work with a specific table. eg. SELECT * FROM [sys].[dm_db_index_physical_stats] (DB_ID(), OBJECT_ID(‘AdventureWorks2008.Person.Address’) , 1, NULL, NULL) AS ddips   Note: Despite me showing that functions can be placed directly in the parameters for this dmv, best practice recommends that functions are not used directly in the function as it is possible that they will fail to return a valid object ID. To be certain of not passing invalid values to this function, and therefore setting an automated process off on the wrong path, declare variables for the OBJECT_IDs and once they have been validated, use them in the function: DECLARE @db_id SMALLINT; DECLARE @object_id INT; SET @db_id = DB_ID(N’AdventureWorks_2008′); SET @object_id = OBJECT_ID(N’AdventureWorks_2008.Person.Address’); IF @db_id IS NULL BEGINPRINT N’Invalid database’; ENDELSE IF @object_id IS NULL BEGINPRINT N’Invalid object’; ENDELSE BEGINSELECT * FROM sys.dm_db_index_physical_stats (@db_id, @object_id, NULL, NULL , ‘LIMITED’); END; GO In cases where the results of querying this dmv don’t have any effect on other processes (i.e. simply viewing the results in the SSMS results area)  then it will be noticed when the results are not consistent with the expected results and in the case of this blog this is the method I have used. So, now we can relate the values in these columns to something that we recognise in the database lets see what those other values in the dmv are all about. The next columns are: We’ll skip partition_number, index_type_desc, alloc_unit_type_desc, index_depth and index_level  as this is a quick look at the dmv and they are pretty self explanatory. The final columns revealed by querying this view in the DEFAULT mode are avg_fragmentation_in_percent. This is the amount that the index is logically fragmented. It will show NULL when the dmv is queried in SAMPLED mode. fragment_count. The number of pieces that the index is broken into. It will show NULL when the dmv is queried in SAMPLED mode. avg_fragment_size_in_pages. The average size, in pages, of a single fragment in the leaf level of the IN_ROW_DATA allocation unit. It will show NULL when the dmv is queried in SAMPLED mode. page_count. Total number of index or data pages in use. OK, so what does this give us? Well, there is an obvious correlation between fragment_count, page_count and avg_fragment_size-in_pages. We see that an index that takes up 27 pages and is in 3 fragments has an average fragment size of 9 pages (27/3=9). This means that for this index there are 3 separate places on the hard disk that SQL Server needs to locate and access to gather the data when it is requested by a DML query. If this index was bigger than 72KB then having it’s data in 3 pieces might not be too big an issue as each piece would have a significant piece of data to read and the speed of access would not be too poor. If the number of fragments increases then obviously the amount of data in each piece decreases and that means the amount of work for the disks to do in order to retrieve the data to satisfy the query increases and this would start to decrease performance. This information can be useful to keep in mind when considering the value in the avg_fragmentation_in_percent column. This is arrived at by an internal algorithm that gives a value to the logical fragmentation of the index taking into account the multiple files, type of allocation unit and the previously mentioned characteristics if index size (page_count) and fragment_count. Seeing an index with a high avg_fragmentation_in_percent value will be a call to action for a DBA that is investigating performance issues. It is possible that tables will have indexes that suffer from rapid increases in fragmentation as part of normal daily business and that regular defragmentation work will be needed to keep it in good order. In other cases indexes will rarely become fragmented and therefore not need rebuilding from one end of the year to another. Keeping this in mind DBAs need to use an ‘intelligent’ process that assesses key characteristics of an index and decides on the best, if any, defragmentation method to apply should be used. There is a simple example of this in the sample code found in the Books OnLine content for this dmv, in example D. There are also a couple of very popular solutions created by SQL Server MVPs Michelle Ufford and Ola Hallengren which I would wholly recommend that you review for much further detail on how to care for your SQL Server indexes. Right, let’s get back on track then. Querying the dmv with the fifth parameter value as ‘DETAILED’ takes longer because it goes through the index and refreshes all data from every level of the index. As this blog is only a quick look a we are going to skate right past ghost_record_count and version_ghost_record_count and discuss avg_page_space_used_in_percent, record_count, min_record_size_in_bytes, max_record_size_in_bytes and avg_record_size_in_bytes. We can see from the details below that there is a correlation between the columns marked. Column 1 (Page_Count) is the number of 8KB pages used by the index, column 2 is how full each page is (how much of the 8KB has actual data written on it), column 3 is how many records are recorded in the index and column 4 is the average size of each record. This approximates to: ((Col1*8) * 1024*(Col2/100))/Col3 = Col4*. avg_page_space_used_in_percent is an important column to review as this indicates how much of the disk that has been given over to the storage of the index actually has data on it. This value is affected by the value given for the FILL_FACTOR parameter when creating an index. avg_record_size_in_bytes is important as you can use it to get an idea of how many records are in each page and therefore in each fragment, thus reinforcing how important it is to keep fragmentation under control. min_record_size_in_bytes and max_record_size_in_bytes are exactly as their names set them out to be. A detail of the smallest and largest records in the index. Purely offered as a guide to the DBA to better understand the storage practices taking place. So, keeping an eye on avg_fragmentation_in_percent will ensure that your indexes are helping data access processes take place as efficiently as possible. Where fragmentation recurs frequently then potentially the DBA should consider; the fill_factor of the index in order to leave space at the leaf level so that new records can be inserted without causing fragmentation so rapidly. the columns used in the index should be analysed to avoid new records needing to be inserted in the middle of the index but rather always be added to the end. * – it’s approximate as there are many factors associated with things like the type of data and other database settings that affect this slightly.  Another great resource for working with SQL Server DMVs is Performance Tuning with SQL Server Dynamic Management Views by Louis Davidson and Tim Ford – a free ebook or paperback from Simple Talk.
