• SQL Server Backup File Significantly Smaller After Table Recreation

  - by userx

  We run automated weekly backups of our SQL Server. The database in question is configured for Simple Recovery. We backup using Full, not differential. Recently, we had to re-create one of our tables with data in it (making 2 varchar fields a couple characters longer). This required running a script which created a new table, copied the data over, and then dropped the old. This worked correctly. Oddly though, our weekly backup files now SHRANK by over 75%! The tables don't have large indexes. All data was copied over correctly (and verified). I've verified that we are doing full and not incremental backups. The new files restore just fine. I can't seem to figure out why the backup files would have shrank so much? I've also noticed that they get about 10 MB larger every week, even though less than that amount of data is being added. I'm guessing that I'm simply not understanding something. Any insight would be appreciated.

• SQL Server Analysis Services, DNS, AD, Kerberos, Connection Issues

  - by ScaleOvenStove

  Running into a very weird issue. Converting servers to Windows 2008/SQL 2008. Have a server, SERVER_A, brand new, setup with Win2k8,Sql2k8 - works. Have a Server SERVER_B, running Windows2003/SQL2005. I want to migrate from SERVER_B to SERVER_A. I have all db's, cubes, etc setup on SERVER_A and it is mimicking functionality. Since users are using Excel to connect to SSAS, they connection string has SERVER_B in it. What I want to do, is, change DNS on the network to point SERVER_B (by name) at the ip of SERVER_A. I have successfully done this with another server, SERVER_C, but I need to do it with SERVER_B. What I have found is that with SERVER_C, after changing DNS, had to remove SERVER_C from AD and then it worked. I could connect to SERVER_C (DB), SERVER_C (SSAS Default Instance) and SERVER_C (SSAS Named instance) and it all was actually connecting to SERVER_A I tried to do the same with with SERVER_B, and no luck. Changed DNS, removed from AD, and it wouldn't connect. Found out that there were some SPN's in AD set up, so removed those and tried again. I then could connect to SERVER_B (DB), SERVER_B (SSAS Named Instance), but not SERVER_B (SSAS Default Instance). I could connect to SERVER_B (SSAS Default Intance WITH the Port #), but I need to be able to connect without the port number. I am at a loss to as why I can't connect to the default instance without a port #. Not sure if it is SPN's in AD, or another AD issue, or something else. Pretty sure it isnt something on the server (because SERVER_C works!) Any insight or suggestions would be greatly helpful!!

• The Database as Intellectual Property

  - by Jonathan Kehayias

  Every so often, a question shows up on the forums in the form of, “How do I prevent anyone from accessing my database schema, including local administrators and sysadmins in SQL Server?”  I usually laugh a little shake my head when I read a question like this because it demonstrates an complete lack of understanding of the power an administrator has over SQL Server.  The simple answer is this: If you don’t want your database schema to ever be accessed or known, don’t distribute your database....(read more)

• New database profiling support in ANTS Performance Profiler

  - by Ben Emmett

  In May last year, the ANTS Performance Profiler team added the ability to profile database requests your application makes to SQL Server or Oracle. The really cool thing is that you’re shown those requests in the application’s call tree, so you can see what .NET code caused those queries to run. It’s particularly helpful if you’re using an ORM which automagically generates and runs queries for you, but which doesn’t necessarily do it in the most efficient way possible. Now by popular demand, we’ve added support for profiling MySQL (or MariaDB) and PostgreSQL, so you can see queries run against those databases too. Some of you have also said that you’re using the Devart dotConnect data providers instead of the native .NET ones, so we’ve added support for those drivers too. Hope it helps! For the record, here’s a list of supported connectors (ones in bold are new): SQL Server .NET Framework Data Provider Devart dotConnect for SQL Server Oracle .NET Framework Data Provider Oracle Data Provider for .NET Devart dotConnect for Oracle MySQL / MariaDB MySQL Connector/Net Devart dotConnect for MySQL PostgreSQL Npgsql .NET Data Provider for PostgreSQL Devart dotConnect for PostgreSQL SQL Server Compact Edition .NET Framework Data Provider for SQL Server Compact Edition Devart dotConnect for SQL Server Pro Have we missed a connector or database which you’d find useful? Tell us about it in the comments or by emailing [email protected]. Ben

• Unicenter Software Delivery 4 not able to connect to MS SQL 2000 Database after W2003 SP2 upgrade

  - by grub

  Hello Everyone Yesterday I installed the Windows Server 2003 Service Pack 2 on a Windows Server 2003 which has Unicenter Software Delivery 4 installed. Prior to the installation I disabled every CA service on the server (Brightstor, SDO , RCO, TNG) and the MS SQL 2000 service. After the installation of the SP2 I enabled the services again but the Unicenter Service is not able to connect to the MS SQL 2000 Database anymore. The database itself is up and running and I can connect to it with the Enterprise Manager. A dbcc checkdb doesnt return any errors on the Unicenter database. The Unicenter service throws the following error messages during startup: IM[1] 27/05 10:38:31,272 Installation Manager in init phase IM[1] 27/05 10:38:31,694 Process IM(L) - [004152] failed to open database SDDATA. dbopen() call failed.

The configuration is the same and the same driver and software versions are used. Do you have any idea what causes the connection issue? Should I deinstall the unicenter service and make a fresh installation on the server or should I remove the Windows Server 2003 SP2? I don't want to remove the SP2 because it's a requirement for WSUS3 SP2 and I really don't want to know how many possible exploits are possible in such an old system ;-) Thank you very much and have a nice day.

• Framework 4 Features: User Propogation to the Database

  - by Anthony Shorten

  Once of the features I mentioned in a previous entry was the ability for Oracle Utilities Application Framework V4 to automatically propogate the end user to the database connection. This bears more explanation. In the past releases of the Oracle Utilities Application Framework, all database connections are pooled and shared within a channel of access. So for example, the online connections on the Business Application Server share a common pool of connections and the batch in a thread pool shares a seperate pool of connections. The connections are pooled for performance reasons (the most expensive part of a typical transaction is opening and closing connections so we save time by having them ready beforehand). The idea is that when a business function needs some SQL to be execute it takes a spare connection from the pool, executes the SQL and then returns the connection back to the pool for reuse. Unfortunelty to support the pool being started and ready before the transactions arrives means that you need to have a shared userid (as you dont know the users who need them beforehand). Therefore each connection uses the same database user to execute the SQL it needs. This is acceptable for executing transactions, generally but does not allow the DBA or other tools to ascertain which end user is actually running the transaction. In Oracle Utilities Application Framework V4, we now set the CLIENT_IDENTIFIER to the end userid (not the Login Id) when the connection is taken from the pool and used and reset it back to blank when returned to the pool. The CLIENT_IDENTIFIER is a feature that is present in the Oracle Database connection information. From a monitoring perspective, when a connection to the database is actively running SQL, the end user is now able to be determined by querying the CLIENT_IDENTIFIER on the session object within the database. This can be done in the DBA's favorite monitoring tool (even just some SQL on the v$session table is enough). This has other implications as well. Oracle sells a lot of other security addons to the database and so do third parties. If a site wants to have additional levels of security or auditing in the database then the CLIENT_IDENTIFIER, if supported, is now available to be recorded or used by those products to provide additional levels of security. This facility was one of the highly "nice to haves" that customers would ask us about so we now allow it to be used to allow finer grained monitoring and additional security facilities. Note: This facility is only available for customers using the Oracle Database versions of our products.

• Why I don't use SSIS checkpoint files

  - by jamiet

  In a recent discussion in regard to general ETL best practises the subject of checkpoint files as a means for package restartability came up and I stated that I was dead against using them. For anyone that may care, here is why: Configuring them is distinctly unintuitive (that's a matter of opinion but if you follow the link I'll wager that you will agree) they don't make any allowance for loop iterations they cannot store variables of type Object they are limited in ability. There are many scenarios where you may want to execute certain containers regardless of whether the package is started from a checkpoint file but the current usage model does not allow for this. they are ignored by eventhandlers, which wouldn't be so bad if there were a way to toggle this behaviour in certain scenarios they dont work properly I'll expand on the last bullet point. I have encountered situations where the behaviour for tasks executing concurrently is unpredictable. That is, sometimes the completion of a task that executes concurrently with a failed/failing task will make it into the checkpoint file and sometimes it won't. This is near-impossible to reproduce but it does happen as my good friend John Welch will hopefully concur (if he is reading). Is anyone out there making successful use of checkpoint files within SSIS? I would be interested in knowing about that if so. @Jamiet

• Writing a SQL Azure Book - Notes

  - by Herve Roggero

  Over the last few months I have had the opportunity to ramp up significantly on SQL Azure.  In fact I will be the co-author of Pro SQL Azure, published by Apress. This is going to be a book on how to best leverage SQL Azure, both from a technology and design standpoint. Talking about design, one of the things I realized is that understanding the key limitations and boundary parameters of Azure in general, and more specifically SQL Azure, will play an important role in making sounds design decisions that both meet reasonable performance requirements and minimize the costs associated with running a cloud computing solution.   The book touches on many design considerations including link encryption, pricing model, design patterns, and also some important performance techniques that need to be leveraged when developing in Azure, including Caching, Lazy Properties and more.   Finally I started working with Shards and how to implement them in Azure to ensure database scalability beyond the current size limitations. Implementing shards is not simple, and the book will address how to create a shard technology within your code to provide a scale-out mechanism for your SQL Azure databases.   As you can see, there are many factors to consider when designing a SQL Azure database. While we can think of SQL Azure as a cloud version of SQL Server, it is best to look at it as a new platform to make sure you don’t make any assumptions on how to best leverage it.

• Fresh Install of SQL Server 2008 doesn't install managment studio. Help!

  - by Jordan S

  Ok I am running Windows 7, 64 bit. I cleaned of SQL server 2005 completely off my system leaving only SQL Compact Edition. I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=01af61e6-2f63-4291-bcad-fd500f6027ff&displaylang=en and installed SQL Server 2008 Express Edition Service Pack 1. After the install, under my start bar menu all i have for SQL configuration tools are the Configuration Manager, Error and Usage Reporting and the Install Center. I don't have the SQL Managment Studio. So I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=08e52ac2-1d62-45f6-9a4a-4b76a8564a2b&displaylang=en and downloaded the SQL Server 2008 Management Studio Express but when I try to install it I get a warning says This program has known compatibility issues and that I need to Install SQL Server 2008 Service Pack 1. I thought that is what I installed. So, I tried to continue running the install but I then get an error message that says Invoke or BeginInvoke can not be called on a Form before it is opened... How can I check if Service pack 1 is installed or not? What should I do?

• Replication keeps popping up on SharePoint databases

  - by Ddono25

  My typical discovery scenario: We receive an alert that the transaction log is growing quickly. We are in Simple Recovery so I go to check it out. Log is already sized to 100GB and is at 80% capacity. I run the "Whats using my log files" script from SQL Server Central and see that Replication is enabled on the database. We do not set up replication, and I don't think Replication can be done on SharePoint content db's as Replication is not supported (requires PK on all tables). This has been occurring on random servers (about 5 so far, all within the past three weeks) and it only occurs on Content Databases. sp_removedbreplication does not always work in removing the Replication either. We have found that we need to run the sp_removedbreplication, change all db owners to SA and reset Recovery Mode to Simple to completely eradicate any vestiges of this bug. How would Replication be enabling itself? We have never set up Replication on these servers. There is no evidence of any type of Replication other than the 'log_reuse_wait_desc' from the DMV query and log growth. Any help on this ghost would be appreciated!

• PHP ORM style of querying

  - by Petah

  Ok so I have made an ORM library for PHP. It uses syntax like so: *(assume that $business_locations is an array)* Business::type(Business:TYPE_AUTOMOTIVE)-> size(Business::SIZE_SMALL)-> left_join(BusinessOwner::table(), BusinessOwner::business_id(), SQL::OP_EQUALS, Business::id())-> left_join(Owner::table(), SQL::OP_EQUALS, Owner::id(), BusinessOwner::owner_id())-> where(Business::location_id(), SQL::in($business_locations))-> group_by(Business::id())-> select(SQL::count(BusinessOwner::id()); Which can also be represented as: $query = new Business(); $query->set_type(Business:TYPE_AUTOMOTIVE); $query->set_size(Business::SIZE_SMALL); $query->left_join(BusinessOwner::table(), BusinessOwner::business_id(), SQL::OP_EQUALS, $query->id()); $query->left_join(Owner::table(), SQL::OP_EQUALS, Owner::id(), BusinessOwner::owner_id()); $query->where(Business::location_id(), SQL::in($business_locations)); $query->group_by(Business::id()); $query->select(SQL::count(BusinessOwner::id()); This would produce a query like: SELECT COUNT(`business_owners`.`id`) FROM `businesses` LEFT JOIN `business_owners` ON `business_owners`.`business_id` = `businesses`.`id` LEFT JOIN `owners` ON `owners`.`id` = `business_owners`.`owner_id` WHERE `businesses`.`type` = 'automotive' AND `businesses`.`size` = 'small' AND `businesses`.`location_id` IN ( 1, 2, 3, 4 ) GROUP BY `businesses`.`id` Please keep in mind that the syntax might not be prefectly correct (I only wrote this off the top of my head) Any way, what do you think of this style of querying? Is the first method or second better/clearer/cleaner/etc? What would you do to improve it?

• OLL Live webcast - Using SQL for Pattern Matching in Oracle Database

  - by KLaker

  If you are interested in learning about our exciting new 12c SQL pattern matching feature then mark your diaries. On Wednesday, October 30th at 8:00 am (US/Pacific time zone) Supriya Ananth, who is one of our top curriculum developers at Oracle, will be hosting an OLL webcast on our new SQL pattern matching feature. The ability to recognize patterns in a sequence of rows has been a capability that was widely desired, but not possible with SQL until now. Row pattern matching in native SQL improves application and development productivity and query efficiency for row-sequence analysis. With Oracle Database 12c you can use the new MATCH_RECOGNIZE clause to perform pattern matching in SQL to do the following: Logically partition and order the data using the PARTITION BY and ORDER BY clauses Use regular expressions syntax to define patterns of rows to seek using the PATTERN clause. These patterns a powerful and expressive feature, applied to the pattern variables you define. Specify the logical conditions required to map a row to a row pattern variable in the DEFINE clause. Define measures, which are expressions usable in the MEASURES clause of the SQL query. For more information and to register for this exciting webcast please visit the OLL Live website, see here: https://apex.oracle.com/pls/apex/f?p=44785:145:116820049307135::::P145_EVENT_ID,P145_PREV_PAGE:461,143.  Please note - if the above link does not work then go to OLL (https://apex.oracle.com/pls/apex/f?p=44785:1:) and click the OLL Live icon (upper right, beneath the Login link or logout link if you are already logged in). The pattern matching webcast is listed on the calendar of events on 30 October.

• The best software for users internet usage

  - by nikospkrk

  Hi, We are a small business using a Vigor 2820 as the internet router, and we'd like to install a software that could report any internet usage from our users. I already tried the "official" software made by Draytek called "SmartMonitor", but is reliability is a real issue as it doesn't seem to keep capturing packets after working 3 to 6hours (randomly), whereas Wireshark keeps capturing packets after that amount of time. As I'm really fed up with this tool, I'm looking for other solutions but I still want the same features: users statistics, websites ranking, users traffic, ... I already enabled the port mirroring feature, so it would be perfect if you could suggest me a port mirroring-based software (ideally freeware). I thought I had found the good one with Etherscout, but it just doesn't launch. I am even open to a tool that would "just" make some reports based on Wireshark captured files (*.pcap). Thank you for any of your suggestion, Nicolas.

About 100M Rows Average: 1k Updates Per Second Hard Drives: RAID 10 SSD MDF --Active Time: 0 Log Drives: 1 SSD LDF - Simple Recovery --Active Time 99.9 --Queue: 8 I do not need a back up of the log so it is set to simple recovery but my bottleneck is still at my log. I get high WAITLOG times and thus it can not update any faster. I can't do bulk updates/transactions and each update needs to be one at a time. Is my only option to increase write performance of the log drives, add a RAID drives? Any suggestions on increasing the performance?

• Use CompiledQuery.Compile to improve LINQ to SQL performance

  - by Michael Freidgeim

  After reading DLinq (Linq to SQL) Performance and in particular Part 4  I had a few questions. If CompiledQuery.Compile gives so much benefits, why not to do it for all Linq To Sql queries? Is any essential disadvantages of compiling all select queries? What are conditions, when compiling makes whose performance, for how much percentage? World be good to have default on application config level or on DBML level to specify are all select queries to be compiled? And the same questions about Entity Framework CompiledQuery Class. However in comments I’ve found answer  of the author ricom 6 Jul 2007 3:08 AM Compiling the query makes it durable. There is no need for this, nor is there any desire, unless you intend to run that same query many times. SQL provides regular select statements, prepared select statements, and stored procedures for a reason.  Linq now has analogs. Also from 10 Tips to Improve your LINQ to SQL Application Performance   If you are using CompiledQuery make sure that you are using it more than once as it is more costly than normal querying for the first time. The resulting function coming as a CompiledQuery is an object, having the SQL statement and the delegate to apply it.  And your delegate has the ability to replace the variables (or parameters) in the resulting query. However I feel that many developers are not informed enough about benefits of Compile. I think that tools like FxCop and Resharper should check the queries  and suggest if compiling is recommended.

• Database Security: The First Step in Pre-Emptive Data Leak Prevention

  - by roxana.bradescu

  With WikiLeaks raising awareness around information leaks and the harm they can cause, many organization are taking stock of their own information leak protection (ILP) strategies in 2011. A report by IDC on data leak prevention stated: Increasing database security is one of the most efficient and cost-effective measures an organization can take to prevent data leaks. By utilizing the data protection, access control, account management, encryption, log management, and other security controls inherent in the database management system, entities can institute first-level control over the widest range of protected information. As a central repository for unstructured data, which is growing at leaps and bounds, the database should be the first layer providing information leakage protection. Unfortunately, most organizations are not taking sufficient steps to protect their databases according to a survey of the Independent Oracle User Group. For example, any operating system administrator or database administrator can access the all the data stored in the database in most organizations. Without any kind of auditing or monitoring. And it's not just administrators, database users can typically access the database with ad-hoc query tools from their desktop and by-pass any application level controls. Despite numerous regulations calling for controls to limit the powers of insiders, most organizations still put too many privileges in the hands of their employees. Time and time again these excess privileges have backfired. Internal agents were implicated in almost half of data breaches according to the Verizon Data Breach Investigations Report and the rate is rising. Hackers also took advantage of these excess privileges very successfully using stolen credentials and SQL injection attacks. But back to the insiders. Who are these insiders and why do they do it? In 2002, the U.S. Secret Service (USSS) behavioral psychologists and CERT information security experts formed the Insider Threat Study team to examine insider threat cases that occurred in US critical infrastructure sectors, and examined them from both a technical and a behavioral perspective. A series of fascinating reports has been published as a result of this work. You can learn more by watching the ISSA Insider Threat Web Conference. So as your organization starts to look at data leak prevention over the coming year, start off by protecting your data at the source - your databases. IDC went on to say: Any enterprise looking to improve its competitiveness, regulatory compliance, and overall data security should consider Oracle's offerings, not only because of their database management capabilities but also because they provide tools that are the first layer of information leak prevention. Learn more about Oracle Database Security solutions and get the whitepapers, demos, tutorials, and more that you need to protect data privacy from internal and external threats.

• Data from a table in 1 DB needed for filter in different DB...

  - by Refracted Paladin

  I have a Win Form, Data Entry, application that uses 4 seperate Data Bases. This is an occasionally connected app that uses Merge Replication (SQL 2005) to stay in Sync. This is working just fine. The next hurdle I am trying to tackle is adding Filters to my Publications. Right now we are replicating 70mbs, compressed, to each of our 150 subscribers when, truthfully, they only need a tiny fraction of that. Using Filters I am able to accomplish this(see code below) but I had to make a mapping table in order to do so. This mapping table consists of 3 columns. A PrimaryID(Guid), WorkerName(varchar), and ClientID(int). The problem is I need this table present in all FOUR Databases in order to use it for the filter since, to my knowledge, views or cross-db query's are not allowed in a Filter Statement. What are my options? Seems like I would set it up to be maintained in 1 Database and then use Triggers to keep it updated in the other 3 Databases. In order to be a part of the Filter I have to include that table in the Replication Set so how do I flag it appropriately. Is there a better way, altogether? SELECT <published_columns> FROM [dbo].[tblPlan] WHERE [ClientID] IN (select ClientID from [dbo].[tblWorkerOwnership] where WorkerID = SUSER_SNAME()) Which allows you to chain together Filters, this next one is below the first one so it only pulls from the first's Filtered Set. SELECT <published_columns> FROM [dbo].[tblPlan] INNER JOIN [dbo].[tblHealthAssessmentReview] ON [tblPlan].[PlanID] = [tblHealthAssessmentReview].[PlanID]
