• Internet doesn't work by default

  - by Adam Martinez

  After upgrading to Precise, I am required to run 'sudo dhclient eth0' in a terminal in order to get the internet to work. Everything worked perfectly fine on Oneiric, so It's really puzzling me. I'm thinking it could possibly be something with the kernel, but who knows. Output of dmesg: [ 0.247891] system 00:01: [io 0x0290-0x030f] has been reserved [ 0.247896] system 00:01: [io 0x0290-0x0297] has been reserved [ 0.247901] system 00:01: [io 0x0880-0x088f] has been

• SQL SERVER – Planned and Unplanned Availablity Group Failovers – Notes from the Field #031

  - by Pinal Dave

  [Note from Pinal]: This is a new episode of Notes from the Fields series. AlwaysOn is a very complex subject and not everyone knows many things about this. The matter of the fact is there is very little information available on this subject online and not everyone knows everything about this. This is why when a very common question related to AlwaysOn comes, people get confused. In this episode of the Notes from the Field series database expert John Sterrett (Group Principal at Linchpin People) explains a very common issue DBAs and Developer faces in their career and is related to Planned and Unplanned Availablity Group Failovers. Linchpin People are database coaches and wellness experts for a data driven world. Read the experience of John in his own words. Whenever a disaster occurs it will be a stressful scenario regardless of how small or big the disaster is. This gets multiplied when it is your first time working with newer technology or the first time you are going through a disaster without a proper run book. Today, were going to help you establish a run book for creating a planned failover with availability groups. To make today’s session simple were going to have two instances of SQL Server 2012 included in an availability group and walk through the steps of doing an unplanned failover.  We will focus on using the user interface and T-SQL to complete the failovers. We are going to use a two replica Availability Group where each replica is in another location. Therefore, we will be covering Asynchronous (non automatic failover) the following is a breakdown of our availability group utilized today. Seeing the following screen might be scary the first time you come across an unplanned failover.  It looks like our test database used in this Availability Group is not functional and it currently isn’t. The database status is not synchronizing which makes sense because the primary replica went down so it couldn’t synchronize. With that said, we can still failover and make it functional while we troubleshoot why we lost our primary replica. To start we are going to right click on the availability group that needs to be restarted and select failover. This will bring up the following wizard, which will walk you through several steps needed to complete the failover using the graphical user interface provided with SQL Server Management Studio (SSMS). You are going to see warning messages simply because we are in Asynchronous commit mode and can not guarantee ‘no data loss’ when we do failover. Just incase you missed it; you get another screen warning you about potential data loss because we are in Asynchronous mode. Next we get to connect to the specific replica we want to become the primary replica after the failover occurs. In our case, we only have two replicas so this is trivial. In order to failover, it’s required to connect to the replica that will become primary.  The following screen shows that the connection has been made successfully. Next, you will see the final summary screen. Once again, this reminds you that the failover action will cause data loss as were using Asynchronous commit mode due to the distance between instances used for disaster recovery. Finally, once the failover is completed you will see the following screen. If you followed along this long you might be wondering what T-SQL scripts are generated for clicking through all the sections of the wizard. If you have used Database Mirroring in the past you might be surprised.  It’s not too different, which makes sense because the data is being replicated via SQL Server endpoints just like the good old database mirroring. Now were going to take a look at how to do a failover with just T-SQL. First, were going to need to open a new query window and run our query in SQLCMD mode. Just incase you haven’t used SQLCMD mode before we will show you how to enable it below. Now you can run the following statement. Notice, we connect to the replica we want to become primary after failover and specify to force failover to allow data loss. We can use the following script to failback over when our primary instance comes back online. -- YOU MUST EXECUTE THE FOLLOWING SCRIPT IN SQLCMD MODE. :Connect SQL2012PROD1 ALTER AVAILABILITY GROUP [AGSQL2] FORCE_FAILOVER_ALLOW_DATA_LOSS; GO Are your servers running at optimal speed or are you facing any SQL Server Performance Problems? If you want to get started with the help of experts read more over here: Fix Your SQL Server.

• Issues with timed out downloads via TomCat?

  - by Ira Baxter

  We get, in our opinion, a lot of failed download attempts and want to understand why. We offer downloads via an email link (typical): http://www.semanticdesigns.com/deliverEval/<productname> This is processed by Tomcat on Linux via a jsp file, with the following code: response.addHeader( "Content-Disposition", "attachment; filename=" + fileTail ); response.addHeader( "Content-Type", "application/x-msdos-program" ); byte[] buf = new byte[8192]; int read; try { java.io.FileInputStream input = new java.io.FileInputStream( filename ); java.io.OutputStream o = response.getOutputStream(); while( ( read = input.read( buf, 0, 8192 ) ) != -1 ){ o.write( buf, 0, read ); } o.flush(); } catch( Exception e ){ util.fatalError( request.getRequestURI(), "Error sending file '" + filename + "' to client", e ); throw e; } We get a lot of reported errors (about 50% error rate): URI --- /deliverEval/download.jsp Code Message: Error sending file '/home/sd/ShippingMasters/DMS/Domains/C/GCC3/Tools/TestCoverage/SD_C~GCC3_TestCoverage.1.6.12.exe' to client Stack Trace ----------- null at org.apache.coyote.tomcat5.OutputBuffer.realWriteBytes(byte[], int, int) (Unknown Source) at org.apache.tomcat.util.buf.ByteChunk.append(byte[], int, int) (Unknown Source) at org.apache.coyote.tomcat5.OutputBuffer.writeBytes(byte[], int, int) (Unknown Source) at org.apache.coyote.tomcat5.OutputBuffer.write(byte[], int, int) (Unknown Source) at org.apache.coyote.tomcat5.CoyoteOutputStream.write(byte[], int, int) (Unknown Source) at org.apache.jsp.deliverEval.download_jsp._jspService(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) (Unknown Source) at org.apache.jasper.runtime.HttpJspBase.service(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) (Unknown Source) at javax.servlet.http.HttpServlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.jasper.servlet.JspServletWrapper.service(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, boolean) (Unknown Source) at org.apache.jasper.servlet.JspServlet.serviceJspFile(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, java.lang.String, java.lang.Throwable, boolean) (Unknown Source) at org.apache.jasper.servlet.JspServlet.service(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) (Unknown Source) at javax.servlet.http.HttpServlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.catalina.core.ApplicationFilterChain.doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.catalina.core.StandardWrapperValve.invoke(org.apache.catalina.Request, org.apache.catalina.Response, org.apache.catalina.ValveContext) (Unknown Source) We don't understand why this rate should be so high. Is there any way to get more information about the cause of the error? It is useful to know that these are pretty big documents, 3-50 megabytes. They reside on the Linux server so reading them is just a local disk read, and is unlikely to be a contributor to the problem. But sheer size might be an issue for the recipients browser? Is this kind of error rate typical for downloads? My personal experience downloading other's documents suggests no; our internal attempts show this to be very reliable, but we're operating on our internal network for such experiments so we're missing the complexity of the intervening internet.

• SQL SERVER – Move Database Files MDF and LDF to Another Location

  - by pinaldave

  When a novice DBA or Developer create a database they use SQL Server Management Studio to create new database. Additionally, the T-SQL script to create a database is very easy as well. You can just write CREATE DATABASE DatabaseName and it will create new database for you. The point to remember here is that it will create the database at the default location specified for SQL Server Instance (this default instance can be changed and we will see that in future blog posts). Now, once the database goes in production it will start to grow. It is not common to keep the Database on the same location where OS is installed. Usually Database files are on SAN, Separate Disk Array or on SSDs. This is done usually for performance reason and manageability perspective. Now the challenges comes up when database which was installed at not preferred default location and needs to move to a different location. Here is the quick tutorial how you can do it. Let us assume we have two folders loc1 and loc2. We want to move database files from loc1 to loc2. USE MASTER; GO -- Take database in single user mode -- if you are facing errors -- This may terminate your active transactions for database ALTER DATABASE TestDB SET SINGLE_USER WITH ROLLBACK IMMEDIATE; GO -- Detach DB EXEC MASTER.dbo.sp_detach_db @dbname = N'TestDB' GO Now move the files from loc1 to loc2. You can now reattach the files with new locations. -- Move MDF File from Loc1 to Loc 2 -- Re-Attached DB CREATE DATABASE [TestDB] ON ( FILENAME = N'F:\loc2\TestDB.mdf' ), ( FILENAME = N'F:\loc2\TestDB_log.ldf' ) FOR ATTACH GO Well, we are done. There is little warning here for you: If you do ROLLBACK IMMEDIATE you may terminate your active transactions so do not use it randomly. Do it if you are confident that they are not needed or due to any reason there is a connection to the database which you are not able to kill manually after review.

• July, the 31 Days of SQL Server DMO’s – Day 29 (sys.dm_os_buffer_descriptors)

  - by Tamarick Hill

  The sys.dm_os_buffer_descriptors Dynamic Management View gives you a look into the data pages that are currently in your SQL Server buffer pool. Just in case you are not familiar with some of the internals to SQL Server and how the engine works, SQL Server only works with objects that are in memory (buffer pool). When an object such as a table needs to be read and it does not exist in the buffer pool, SQL Server will read (copy) the necessary data page(s) from disk into the buffer pool and cache it. Caching takes place so that it can be reused again and prevents the need of expensive physical reads. To better illustrate this DMV, lets query it against our AdventureWorks2012 database and view the result set. SELECT * FROM sys.dm_os_buffer_descriptors WHERE database_id = db_id('AdventureWorks2012') The first column returned from this result set is the database_id column which identifies the specific database for a given row. The file_id column represents the file that a particular buffer descriptor belongs to. The page_id column represents the ID for the data page within the buffer. The page_level column represents the index level of the data page. Next we have the allocation_unit_id column which identifies a unique allocation unit. An allocation unit is basically a set of data pages. The page_type column tells us exactly what type of page is in the buffer pool. From my screen shot above you see I have 3 distinct type of Pages in my buffer pool, Index, Data, and IAM pages. Index pages are pages that are used to build the Root and Intermediate levels of a B-Tree. A Data page would represent the actual leaf pages of a clustered index which contain the actual data for the table. Without getting into too much detail, an IAM page is Index Allocation Map page which track GAM (Global Allocation Map) pages which in turn track extents on your system. The row_count column details how many data rows are present on a given page. The free_space_in_bytes tells you how much of a given data page is still available, remember pages are 8K in size. The is_modified signifies whether or not a page has been changed since it has been read into memory, .ie a dirty page. The numa_node column represents the Nonuniform memory access node for the buffer. Lastly is the read_microsec column which tells you how many microseconds it took for a data page to be read (copied) into the buffer pool. This is a great DMV for use when you are tracking down a memory issue or if you just want to have a look at what type of pages are currently in your buffer pool. For more information about this DMV, please see the below Books Online link: http://msdn.microsoft.com/en-us/library/ms173442.aspx Follow me on Twitter @PrimeTimeDBA

• How to recreate spfile on Exadata?

  - by Bandari Huang

  Copy spfile from the ASM diskgroup to local disk by using the ASMCMD command line tool.  ASMCMD> pwd +DATA_DM01/EDWBASE ASMCMD> ls -l Type Redund Striped Time Sys Name Y CONTROLFILE/ Y DATAFILE/ Y ONLINELOG/ Y PARAMETERFILE/ Y TEMPFILE/ N spfileedwbase.ora => +DATA_DM01/EDWBASE/PARAMETERFILE/spfile.355.800017117 ASMCMD> cp +DATA_DM01/EDWBASE/spfileedwbase.ora /home/oracle/spfileedwbase.ora.bak Copy the context from spfileedwbase.ora.bak to initedwbase.ora except garbled character. Using above initedwbase.ora, start one of the RAC instances to the mount phase.   SQL> startup mount pfile=/home/oracle/initedwbase.ora Ensure one of the database instances is mounted before attempting to recreate the spfile.  SQL> select INSTANCE_NAME,HOST_NAME,STATUS from v$instance; INSTANCE_NAME HOST_NAME  STATUS ------------- ---------  ------ edwbase1      dm01db01   MOUNTED Create the new spfile. SQL> create spfile='+DATA_DM01/EDWBASE/spfileedwbase.ora' from pfile='/home/oracle/initedwbase.ora'; ASMCMD will show that a new spfile has been created as the alias spfilerac2.ora is now pointing to a new spfile under the PARAMETER directory in ASM.

The spfile containing the parameter preventing startups should be removed from ASM. In this case the file spfile.355.800017117 can be removed because spfile.356.800013581 is the current spfile.

• Finally home - and something fully off topic

  - by Mike Dietrich

  Arrived at Munich Pasing last night at 0:50am ... finally :-) On Sunday I've left the Dylan Hotel in Dublin (thanks to the staff there as well: you were REALLY helpful!!) around 7:30pm to go to the port - and came home on Tuesday morning 1:15am. So all together 29:45hrs door-to-door - not bad for nearly 2000km just relying on public transport. And could have been faster if there were seats in ealier TGV's left. But I don't complain at all ;-) Just checked the website of Dublin Airport - it says currently: 17.00pm: Latest on flight disruptions at Dublin Airport The IAA have advised us that based on the latest Volcanic Ash Advisory Centre London Dublin Airport will remain closed for all inbound and outbound commercial flights until 20.00hours. This effectively means that no flights will land or take off at Dublin Airport until then. A further update will be posted this afternoon. When traveling I have always my iPod with me. It has gotten a bit old now (I think I've bought it 3 years ago in November 2007) but it has a 160GB hard disk in it so it fits most of my music collection (not the entire collection anymore as I'm currently re-riping everything to Apple Lossless because at least for my ears it makes a big difference - but I listen to good ol' vinyl as well ...and I don't download compressed music ;-) ). The battery of my little travel companion is still good for more than 20 hours consistent music playback - and there was a band from Texas being in my ears most of the whole journey called Midlake. I haven't heard of them before until I asked a lady at a Munich store some few weeks ago what she's playing on the speakers in the shop. She was amazed and came back with the CD cover but I hesitated to buy it as I always want to listen the tunes before - and at this day I had no time left to do so. But in Dublin I had a bit of spare time on Saturday and I always enter record stores - and the Tower Records was the sort of store I really enjoy and so I've spent there nearly two hours - leaving with 3 Midlake CDs in my bag. So if you are interested just listen those tunes which may remind some people on Fleetwood Mac: As I said in the title, fully off topic ;-)

• Graphics card fan is loud (additional graphics card drivers cause problems)

  - by tk4muffin

  Okay this explanation is a bit longer ... but I start at the beginning: I've been using Windows 7 for a very long time, shortly after the release of v12.10 I installed Ubuntu via Windows installer. Everything worked fine but the fan of the graphics card. After a bit of research I found out, that I just had to select a different driver (nvidia-current (proprietary, tested) worked pretty well). This also fixed some graphical bugs when I just logged into my account. Due to my university I got a MSDNAA-Account (allows me to download every Windows OS for free). I downloaded and installed Windows 8. After configuration I installed ubuntu via the Windows installer once again and the first couple launches of ubuntu went well. Suddenly ubuntu didn't launched anymore...caused by some hard-disk errors and had no clue what to do. So I kept working on Windows 8 - unfortunately. After playing around with the new Windows, I put my PC to sleep-mode. I couldn't wake my PC up and it wasn't responding to anything (neither mouse-movement, -clicks or keyboard strokes, nor the power-button and the reset-button worked), so I pulled the plug. Turns out, this was a huge mistake. Somehow the BIOS broke and after restarting a couple of times, the BIOS repaired itself. Neither Windows 8, nor ubuntu where bootable. Now I had to install ubuntu several times, because after rebooting unity was hidden and I didn't know what the problem was and how to fix it. I finally realized that this problem was caused by the graphics card driver, which I've changed to the nvidia-current (This dirver worked fine before my PC "crashed"). So I installed Windows 8 again and after a bit of usage I installed ubuntu once again (via DVD). The booting of ubuntu and windows works fine - so far. But I'm still not able to change the graphics card driver without unity hiding away after restarting the OS. The noisy fan is really disturbing my work... PC Specs: Processor: Intel Core 2 Duo COU E8400 @ 3GHz x2 Memory: 7.8 GB OS type: 64-bit Graphics Card: GeForce 9600 GT Motherboard: Asus P5Q I hope the information given are enough.

• Customer Support Spotlight: Clemson University

  - by cwarticki

  I've begun a Customer Support Spotlight series that highlights our wonderful customers and Oracle loyalists.  A week ago I visited Clemson University.  As I travel to visit and educate our customers, I provide many useful tips/tricks and support best practices (as found on my blog and twitter). Most of all, I always discover an Oracle gem who deserves recognition for their hard work and advocacy. Meet George Manley.  George is a Storage Engineer who has worked in Clemson's Data Center all through college, partially in the Hardware Architecture group and partially in the Storage group. George and the rest of the Storage Team work with most all of the storage technologies that they have here at Clemson. This includes a wide array of different vendors' disk arrays, with the most of them being Oracle/Sun 2540's.  He also works with SAM/QFS, ACSLS, and our SL8500 Tape Libraries (all three Oracle/Sun products). (pictured L to R, Matt Schoger (Oracle), Mark Flores (Oracle) and George Manley) George was kind enough to take us for a data center tour.  It was amazing.  I rarely get to see the inside of data centers, and this one was massive. Clemson Computing and Information Technology’s physical resources include the main data center located in the Information Technology Center at the Innovation Campus and Technology Park. The core of Clemson’s computing infrastructure, the data center has 21,000 sq ft of raised floor and is powered by a 14MW substation. The ITC power capacity is 4.5MW.  The data center is the home of both enterprise and HPC systems, and is staffed by CCIT staff on a 24 hour basis from a state of the art network operations center within the ITC. A smaller business continuance data center is located on the main campus.  The data center serves a wide variety of purposes including HPC (supercomputing) resources which are shared with other Universities throughout the state, the state's medicaid processing system, and nearly all other needs for Clemson University. Yes, that's no typo (14,256 cores and 37TB of memory!!! Thanks for the tour George and thank you very much for your time.  The tour was fantastic. I enjoyed getting to know your team and I look forward to many successes from Clemson using Oracle products. -Chris WartickiGlobal Customer Management

• SQL Saturday 43 in Redmond

  - by AjarnMark

  I attended my first SQLSaturday a couple of days ago, SQLSaturday #43 in Redmond (at Microsoft).  I got there really early, primarily because I forgot how fast I can get there from my home when nobody else is on the road.  On a weekday in rush hour traffic, that would have taken two hours to get there.  I gave myself 90 minutes, and actually got there in about 45.  Crazy! I made the mistake of going to the main Microsoft campus, but that’s not where the event was being held.  Instead it was in a big Microsoft conference center on the other side of the highway.  Fortunately, I had the address with me and quickly realized my mistake.  When I got back on track, I noticed that there were bright yellow signs out on the street corner that looked like they said they were for SOL Saturday, which actually was appropriate since it was the sunniest day around here in a long time. Since I was there so early, the registration was just getting setup, so I found Greg Larsen who was coordinating things and offered to help.  He put me to work with a group of people organizing the pre-printed raffle tickets and stuffing swag bags. I had never been to a SQLSaturday before this one, so I wasn’t exactly sure what to expect even though I have read about a few on some blogs.  It makes sense that each one will be a little bit different since they are almost completely volunteer driven, and the whole concept is still in its early stages.  I have been to the PASS Summit for the last several years, and was hoping for a smaller version of that.  Now, it’s not really fair to compare one free day of training run entirely by volunteers with a multi-day, $1,000+ event put on under the direction of a professional event management company.  But there are some parallels. At this SQLSaturday, there was no opening general session, just coffee and pastries in the common area / expo hallway and straight into the first group of sessions.  I don’t know if that was because there was no single room large enough to hold everyone, or for other reasons.  This worked out okay, but the organization guy in me would have preferred to have even a 15 minute welcome message from the organizers with a little overview of the day.  Even something as simple as, “Thanks to persons X, Y, and Z for helping put this together…Sessions will start in 20 minutes and are all in rooms down this hallway…the bathrooms are on the other side of the conference center…lunch today is pizza and we would like to thank sponsor Q for providing it.”  It doesn’t need to be much, certainly not a full-blown Keynote like at the PASS Summit, but something to use as a rallying point to pull everyone together and get the day off to an official start would be nice.  Again, there may have been logistical reasons why that was not feasible here.  I’m just putting out my thoughts for other SQLSaturday coordinators to consider. The event overall was great.  I believe that there were over 300 in attendance, and everything seemed to run smoothly.  At least from an attendee’s point of view where there was plenty of muffins in the morning and pizza in the afternoon, with plenty of pop to drink.  And hey, if you’ve got the food and drink covered, a lot of other stuff could go wrong and people will be very forgiving.  But as I said, everything appeared to run pretty smoothly, at least until Buck Woody showed up in his Oracle shirt.  Other than that, the volunteers did a great job! I was a little surprised by how few people in my own backyard that I know.  It makes sense if you really think about it, given how many companies must be using SQL Server around here.  I guess I just got spoiled coming into the PASS Summit with a few contacts that I already knew would be there.  Perhaps I have been spending too much time with too few people at the Summits and I need to step out and meet more folks.  Of course, it also is different since the Summit is the big national event and a number of the folks I know are spread out across the country, so the Summit is the only time we’re all in the same place at the same time.  I did make a few new contacts at SQLSaturday, and bumped into a couple of people that I knew (and a couple others that I only knew from Twitter, and didn’t even realize that they were here in the area). Other than the sheer entertainment value of Buck Woody’s session, the one that was probably the greatest value for me was a quick introduction to PowerShell.  I have not done anything with it yet, but I think it will be a good tool to use to implement my plans for automated database recovery testing.  I saw just enough at the session to take away some of the intimidation factor, and I am getting ready to jump in and see what I can put together in the next few weeks.  And that right there made the investment worthwhile.  So I encourage you, if you have the opportunity to go to a SQLSaturday event near you, go for it!

• How to restore your production database without needing additional storage

  - by David Atkinson

  Production databases can get very large. This in itself is to be expected, but when a copy of the database is needed the database must be restored, requiring additional and costly storage.  For example, if you want to give each developer a full copy of your production server, you'll need n times the storage cost for your n-developer team. The same is true for any test databases that are created during the course of your project lifecycle. If you've read my previous blog posts, you'll be aware that I've been focusing on the database continuous integration theme. In my CI setup I create a "production"-equivalent database directly from its source control representation, and use this to test my upgrade scripts. Despite this being a perfectly valid and practical thing to do as part of a CI setup, it's not the exact equivalent to running the upgrade script on a copy of the actual production database. So why shouldn't I instead simply restore the most recent production backup as part of my CI process? There are two reasons why this would be impractical. 1. My CI environment isn't an exact copy of my production environment. Indeed, this would be the case in a perfect world, and it is strongly recommended as a good practice if you follow Jez Humble and David Farley's "Continuous Delivery" teachings, but in practical terms this might not always be possible, especially where storage is concerned. It may just not be possible to restore a huge production database on the environment you've been allotted. 2. It's not just about the storage requirements, it's also the time it takes to do the restore. The whole point of continuous integration is that you are alerted as early as possible whether the build (yes, the database upgrade script counts!) is broken. If I have to run an hour-long restore each time I commit a change to source control I'm just not going to get the feedback quickly enough to react. So what's the solution? Red Gate has a technology, SQL Virtual Restore, that is able to restore a database without using up additional storage. Although this sounds too good to be true, the explanation is quite simple (although I'm sure the technical implementation details under the hood are quite complex!) Instead of restoring the backup in the conventional sense, SQL Virtual Restore will effectively mount the backup using its HyperBac technology. It creates a data and log file, .vmdf, and .vldf, that becomes the delta between the .bak file and the virtual database. This means that both read and write operations are permitted on a virtual database as from SQL Server's point of view it is no different from a conventional database. Instead of doubling the storage requirements upon a restore, there is no 'duplicate' storage requirements, other than the trivially small virtual log and data files (see illustration below). The benefit is magnified the more databases you mount to the same backup file. This technique could be used to provide a large development team a full development instance of a large production database. It is also incredibly easy to set up. Once SQL Virtual Restore is installed, you simply run a conventional RESTORE command to create the virtual database. This is what I have running as part of a nightly "release test" process triggered by my CI tool. RESTORE DATABASE WidgetProduction_virtual FROM DISK=N'C:\WidgetWF\ProdBackup\WidgetProduction.bak' WITH MOVE N'WidgetProduction' TO N'C:\WidgetWF\ProdBackup\WidgetProduction_WidgetProduction_Virtual.vmdf', MOVE N'WidgetProduction_log' TO N'C:\WidgetWF\ProdBackup\WidgetProduction_log_WidgetProduction_Virtual.vldf', NORECOVERY, STATS=1, REPLACE GO RESTORE DATABASE mydatabase WITH RECOVERY   Note the only change from what you would do normally is the naming of the .vmdf and .vldf files. SQL Virtual Restore intercepts this by monitoring the extension and applies its magic, ensuring the 'virtual' restore happens rather than the conventional storage-heavy restore. My automated release test then applies the upgrade scripts to the virtual production database and runs some validation tests, giving me confidence that were I to run this on production for real, all would go smoothly. For illustration, here is my 8Gb production database: And its corresponding backup file: Here are the .vldf and .vmdf files, which represent the only additional used storage for the new database following the virtual restore.   The beauty of this product is its simplicity. Once it is installed, the interaction with the backup and virtual database is exactly the same as before, as the clever stuff is being done at a lower level. SQL Virtual Restore can be downloaded as a fully functional 14-day trial. Technorati Tags: SQL Server

• Megjelent az Oracle Enterprise Manager 11g

  - by Lajos Sárecz

  Megjelent és letöltheto az Oracle Enterprise Manager 11gR1. Remélem az olvasók közül többen látták már a bejelentés videóját. Aki lemaradt volna róla bepótolhatja itt. Az új verzió számos újdonságot tartalmaz, melyek röviden összefoglalva az alábbiak: Eloször is az új verzió célja az alkalmazások üzemeltetése üzleti szemszögbol (Business Driven Application Management). A hagyományos komponens alapú rendszer menedzsment megközelítése egyszeruen nem állja meg a helyét az mai IT világában. Ezzel szemben a Business Driven Application Management segíti az üzemeltetoket, hogy az üzletet a leheto leghatékonyabban szolgálják ki, aminek eredményeképp az üzleti eredmények a legoptimálisabban alakulhatnak. A Business Driven Application Management elérése érdekében a 11gR1 a 10g-ben már elérheto végfelhasználói élmény monitorozásra épít. Ezzel a képességgel az IT sokkal jobban megérti, hogy a felhasználók hogyan használják az alkalmazásokat és eközben mit tapasztalnak. Ezt kiegészítve az új verzió fejlettebb üzleti tranzakció menedzsment képességekkel rendelkezik, ezáltal könnyebbé és gyorsabbá teszi a felhasználók számára problémát jelento tranzakciók javítását. Másodsorban az új verzió az alkalmazástól a diszk rétegig (Integrated Application-to-Disk Management) támogatja az üzemeltetést. Mivel minden egyes réteg képes befolyásolni a felhasználói élményt, ezért amint a felhasználókat érinto probléma detektálásra kerül, szükséges az érintett réteg részletes diagnosztikája, elemzése. Az Oracle Enterprise Manager 11gR1 natív támogatást ad az Oracle Database 11gR2, Exadata V2 és Fusion Middleware 11g termékekre. Az összetett alkalmazások menedzsmentjét támogató JVM Diagnosztika és Composite Application Monitoring and Modeler immár szerves részét képezik az új verziónak. Sot, az Enterprise Manager Grid Control és az Enterprise Manager Ops Center elso integrációs lépcsoje is elkészült, így a hardver szintu események is központilag monitorozhatók a Grid Control felületérol. Végül pedig az új verzió integrált rendszer menedzsement és támogatás (Integrated Systems Management and Support) képességgel rendelkezik. Ez azt jelenti, hogy az Oracle Enterprise Manager 11g integrálja a probléma diagnosztizálás és megoldás munkafolyamatát azáltal, hogy közvetlenül a Grid Control-ból lehetségessé válik a My Oracle Support szolgáltatásainak igénybevétele, mint például a szükséges patch-ek letöltése, service request nyitása, stb. Az Oracle support személyzete pedig az Enterprise Manager konfiguráció kezelési képességei révén azonnal információt gyujthetnek a környezetrol, hogy felgyorsuljon a probléma megoldás ideje. Ez a szoros integráció az Oracle Enterprise Manager és a My Oracle Support között segítheti ügyfeleinket a leghatékonyabb Oracle üzemeltetés elérésében. A következo hetekben igyekszem további részletekkel szolgálni, amint én is megismerem az új verzió képességeit. Az új verzió jelenleg 32 és 64 bites Linuxra érheto el. További portolások a következo hetekben várhatók.

• Tuning Red Gate: #4 of Some

  - by Grant Fritchey

  First time connecting to these servers directly (keys to the kingdom, bwa-ha-ha-ha. oh, excuse me), so I'm going to take a look at the server properties, just to see if there are any issues there. Max memory is set, cool, first possible silly mistake clear. In fact, these look to be nicely set up. Oh, I'd like to see the ANSI Standards set by default, but it's not a big deal. The default location for database data is the F:\ drive, where I saw all the activity last time. Cool, the people maintaining the servers in our company listen, parallelism threshold is set to 35 and optimize for ad hoc is enabled. No shocks, no surprises. The basic setup is appropriate. On to the problem database. Nothing wrong in the properties. The database is in SIMPLE recovery, but I think it's a reporting system, so no worries there. Again, I'd prefer to see the ANSI settings for connections, but that's the worst thing I can see. Time to look at the queries, tables, indexes and statistics because all the information I've collected over the last several days suggests that we're not looking at a systemic problem (except possibly not enough memory), but at the traditional tuning issues. I just want to note that, I started looking at the system, not the queries. So should you when tuning your environment. I know, from the data collected through SQL Monitor, what my top poor performing queries are, and the most frequently called, etc. I'm starting with the most frequently called. I'm going to get the execution plan for this thing out of the cache (although, with the cache dumping constantly, I might not get it). And it's not there. Called 1.3 million times over the last 3 days, but it's not in cache. Wow. OK. I'll see what's in cache for this database: SELECT  deqs.creation_time,         deqs.execution_count,         deqs.max_logical_reads,         deqs.max_elapsed_time,         deqs.total_logical_reads,         deqs.total_elapsed_time,         deqp.query_plan,         SUBSTRING(dest.text, (deqs.statement_start_offset / 2) + 1,                   (deqs.statement_end_offset - deqs.statement_start_offset) / 2                   + 1) AS QueryStatement FROM    sys.dm_exec_query_stats AS deqs         CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest         CROSS APPLY sys.dm_exec_query_plan(deqs.plan_handle) AS deqp WHERE   dest.dbid = DB_ID('Warehouse') AND deqs.statement_end_offset > 0 AND deqs.statement_start_offset > 0 ORDER BY deqs.max_logical_reads DESC ; And looking at the most expensive operation, we have our first bad boy: Multiple table scans against very large sets of data and a sort operation. a sort operation? It's an insert. Oh, I see, the table is a heap, so it's doing an insert, then sorting the data and then inserting into the primary key. First question, why isn't this a clustered index? Let's look at some more of the queries. The next one is deceiving. Here's the query plan: You're thinking to yourself, what's the big deal? Well, what if I told you that this thing had 8036318 reads? I know, you're looking at skinny little pipes. Know why? Table variable. Estimated number of rows = 1. Actual number of rows. well, I'm betting several more than one considering it's read 8 MILLION pages off the disk in a single execution. We have a serious and real tuning candidate. Oh, and I missed this, it's loading the table variable from a user defined function. Let me check, let me check. YES! A multi-statement table valued user defined function. And another tuning opportunity. This one's a beauty, seriously. Did I also mention that they're doing a hash against all the columns in the physical table. I'm sure that won't lead to scans of a 500,000 row table, no, not at all. OK. I lied. Of course it is. At least it's on the top part of the Loop which means the scan is only executed once. I just did a cursory check on the next several poor performers. all calling the UDF. I think I found a big tuning opportunity. At this point, I'm typing up internal emails for the company. Someone just had their baby called ugly. In addition to a series of suggested changes that we need to implement, I'm also apologizing for being such an unkind monster as to question whether that third eye & those flippers belong on such an otherwise lovely child.

• How do I get my blacked out ttys back?

  - by con-f-use

  Original Question: After I replaced my Ubuntu 10.10 with 11.04 all I get when I Strg+Alt+F1-6 into a tty is a black screen. Also when I boot there's a while of black screen after grub2 menu is displayed. Then until just before gnome starts it stays black. I have an Nvida Geforce Quadro FX 770M on my HP EliteBook 8530w. How do I get my ttys (aka 'virtual terminals') to work again? My effords in chronological order: So grub and gfx-payload seems to be the problem, I figured. I went along with this guide for higher tty resolution. Which led to the grub2 menu displaying in my native resolution rather than 800x600. The black screen problem remains. I googlehit some bugreports on other nvidia crads having that problem. I tried uninstalling the nvidia driver. No effect. Also tried different resolutions With an older version of the kernel it works. Though not perfectly. The ttys are usable, black screen between grub2 menu and gnome start remains. Not really a solution. Tried so much, that I lost track. Reinstalled grub2 and linux-image-2.6.38-8-generic. Then did this to my /etc/default/grub in accordance with the aforementioned guide (/etc/grub.d/00_header edited as well): GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 #GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=3 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` #GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_GFXMODE=1680x1050x32 To my surprise I can now use my ttys in native resolution. Black screen between grub2 menu and gnome login screen is still there though. That is annoying since I also use an encrypted disk thus having to enter my passphrase in total dark... Still looking for a solution but urgency is low. Downloaded and installed a later version of nvidia driver. No difference to last edit. Tried GRUB_CMDLINE_LINUX="vga="-parameter. No effect. nomodeset has no effect. not even in combination with vga=... Tried echo FRAMEBUFFER=y > /etc/initramfs-tools/conf.d/splash no effect (see comment) On the verge of resignation... Bounty period soon to end.

• VSDB to SSDT Part 1 : Converting projects and trimming excess files

  - by Etienne Giust

  Visual Studio 2012 introduces a change regarding Database Projects : they now use the SSDT technology, which means old VS2010 database projects (VSDB projects) need to be converted. Hopefully, VS2012 does that for you and it is quite painless, but in my case some unnecessary artifacts from the old project were left in place.  Also, when reopening the solution, database projects appeared unconverted even if I had converted them in the previous session and saved the solution.   Converting the project(s) When opening your Visual Studio 2010 solution with Visual Studio 2012, every standard project should be converted by default, but Visual Studio will ask you about your database projects : “Functional changes required Visual Studio will automatically make functional changes to the following projects in order to open them. The project behavior will change as a result. You will be able to open these projects in this version and Visual Studio 2010 SP1.” If you accept, your project is converted. And it should compile with no errors right away except if you have dependencies to dbschema files which are no longer supported.   The output of a SSDT project is a dacpac file which replaces the dbschema file you were accustomed to. References to dacpac files can be added to SSDT projects in the same fashion references to dbschema could be added to VSDB projects.   Cleaning up You will notice that your project file is now a sqlproj file but the old dbproj is still here. In fact at that point you can still reopen the solution in Visual Studio 2010 and everything should show up.   If like me you plan on using VS2012 exclusively, you can get rid of the following files which are still on your disk and in your source control : the dbproj and dbproj.vspscc files Properties/Database.sqlcmdvars Properties/Database.sqldeployment Properties/Database.sqlpermissions Properties/Database.sqlsettings   You might wonder where the information which used to be in the Properties files is now stored. Permissions : a Permissions.sql was created at the root level of your project. Note that when you create a new database project and import a database using the Schema Compare capabilities from Visual Studio, imported table and stored procedure definition files will hold the permission information (along with constraints and, indexes) SQLVars : they are defined inside the publish.xml files Deployment : they are also in the publish.xml files Settings : I was unable to find where those are now. I suppose they are not defined anymore   But Visual Studio still says my database projects should be converted ! I had this error upon closing and then re-opening the solution : my database projects would appear unconverted even though I did all the necessary steps previously.   Easy solution : remove those projects from the solution and add them again (the sqlproj files).   More For those who run into problems when converting from VSDB to SSDT, I suggest reading the following post : http://blogs.msdn.com/b/ssdt/archive/2011/11/21/top-vsdb-gt-ssdt-project-conversion-issues.aspx   Also interesting, is a side by side comparison of VSDB and SSDT project features : http://blogs.msdn.com/b/ssdt/archive/2011/11/21/sql-server-data-tools-ctp4-vs-vs2010-database-projects.aspx
