  • MCM Lab exam this week

    - by Rob Farley
    In two days I’ll’ve finished the MCM Lab exam, 88-971. If you do an internet search for 88-971, it’ll tell you the answer is –883. Obviously. It’ll also give you a link to the actual exam page, which is useful too, once you’ve finished being distracted by the calculator instead of going to the thing you’re actually looking for. (Do people actually search the internet for the results of mathematical questions? Really?) The list of Skills Measured for this exam is quite short, but can essentially be broken down into one word “Anything”. The Preparation Materials section is even better. Classroom Training – none available. Microsoft E-Learning – none available. Microsoft Press Books – none available. Practice Tests – none available. But there are links to Readiness Videos and a page which has no resources listed, but tells you a list of people who have already qualified. Three in Australia who have MCM SQL Server 2008 so far. The list doesn’t include some of the latest batch, such as Jason Strate or Tom LaRock. I’ve used SQL Server for almost 15 years. During that time I’ve been awarded SQL Server MVP seven times, but the MVP award doesn’t actually mean all that much when considering this particular certification. I know lots of MVPs who have tried this particular exam and failed – including Jason and Tom. Right now, I have no idea whether I’ll pass or not. People tell me I’ll pass no problem, but I honestly have no idea. There’s something about that “Anything” aspect that worries me. I keep looking at the list of things in the Readiness Videos, and think to myself “I’m comfortable with Resource Governor (or whatever) – that should be fine.” Except that then I feel like I maybe don’t know all the different things that can go wrong with Resource Governor (or whatever), and I wonder what kind of situations I’ll be faced with. And then I find myself looking through the stuff that’s explained in the videos, and wondering what kinds of things I should know that I don’t, and then I get amazingly bored and frustrated (after all, I tell people that these exams aren’t supposed to be studied for – you’ve been studying for the last 15 years, right?), and I figure “What’s the worst that can happen? A fail?” I’m told that the exam provides a list of scenarios (maybe 14 of them?) and you have 5.5 hours to complete them. When I say “complete”, I mean complete – you don’t get to leave them unfinished, that’ll get you ‘nil points’ for that scenario. Apparently no-one gets to complete all of them. Now, I’m a consultant. I get called on to fix the problems that people have on their SQL boxes. Sometimes this involves fixing corruption. Sometimes it’s figuring out some performance problem. Sometimes it’s as straight forward as getting past a full transaction log; sometimes it’s as tricky as recovering a database that has lost its metadata, without backups. Most situations aren’t a problem, but I also have the confidence of being able to do internet searches to verify my maths (in case I forget it’s –883). In the exam, I’ll have maybe twenty minutes per scenario (but if I need longer, I’ll have to take longer – no point in stopping half way if it takes more than twenty minutes, unless I don’t see an end coming up), so I’ll have time constraints too. And of course, I won’t have any of my usual tools. I can’t take scripts in, I can’t take staff members. Hopefully I can use the coffee machine that will be in the room. I figure it’s going to feel like one of those days when I’ve gone into a client site, and found that the problems are way worse than I expected, and that the site is down, with people standing over me needing me to get things right first time... ...so it should be fine, I’ve done that before. :) If I do fail, it won’t make me any less of a consultant. It won’t make me any less able to help all of my clients (including you if you get in touch – hehe), it’ll just mean that the particular problem might’ve taken me more than the twenty minutes that the exam gave me. @rob_farley PS: Apparently the done thing is to NOT advertise that you’re sitting the exam at a particular time, only that you’re expecting to take it at some point in the future. I think it’s akin to the idea of not telling people you’re pregnant for the first few months – it’s just in case the worst happens. Personally, I’m happy to tell you all that I’m going to take this exam the day after tomorrow (which is the 19th in the US, the 20th here). If I end up failing, you can all commiserate and tell me that I’m not actually as unqualified as I feel.

  • PASS Summit 2011 &ndash; Part III

    - by Tara Kizer
    Well we’re about a month past PASS Summit 2011, and yet I haven’t finished blogging my notes! Between work and home life, I haven’t been able to come up for air in a bit.  Now on to my notes… On Thursday of the PASS Summit 2011, I attended Klaus Aschenbrenner’s (blog|twitter) “Advanced SQL Server 2008 Troubleshooting”, Joe Webb’s (blog|twitter) “SQL Server Locking & Blocking Made Simple”, Kalen Delaney’s (blog|twitter) “What Happened? Exploring the Plan Cache”, and Paul Randal’s (blog|twitter) “More DBA Mythbusters”.  I think my head grew two times in size from the Thursday sessions.  Just WOW! I took a ton of notes in Klaus' session.  He took a deep dive into how to troubleshoot performance problems.  Here is how he goes about solving a performance problem: Start by checking the wait stats DMV System health Memory issues I/O issues I normally start with blocking and then hit the wait stats.  Here’s the wait stat query (Paul Randal’s) that I use when working on a performance problem.  He highlighted a few waits to be aware of such as WRITELOG (indicates IO subsystem problem), SOS_SCHEDULER_YIELD (indicates CPU problem), and PAGEIOLATCH_XX (indicates an IO subsystem problem or a buffer pool problem).  Regarding memory issues, Klaus recommended that as a bare minimum, one should set the “max server memory (MB)” in sp_configure to 2GB or 10% reserved for the OS (whichever comes first).  This is just a starting point though! Regarding I/O issues, Klaus talked about disk partition alignment, which can improve SQL I/O performance by up to 100%.  You should use 64kb for NTFS cluster, and it’s automatic in Windows 2008 R2. Joe’s locking and blocking presentation was a good session to really clear up the fog in my mind about locking.  One takeaway that I had no idea could be done was that you can set a timeout in T-SQL code view LOCK_TIMEOUT.  If you do this via the application, you should trap error 1222. Kalen’s session went into execution plans.  The minimum size of a plan is 24k.  This adds up fast especially if you have a lot of plans that don’t get reused much.  You can use sys.dm_exec_cached_plans to check how often a plan is being reused by checking the usecounts column.  She said that we can use DBCC FLUSHPROCINDB to clear out the stored procedure cache for a specific database.  I didn’t know we had this available, so this was great to hear.  This will be less intrusive when an emergency comes up where I’ve needed to run DBCC FREEPROCCACHE. Kalen said one should enable “optimize for ad hoc workloads” if you have an adhoc loc.  This stores only a 300-byte stub of the first plan, and if it gets run again, it’ll store the whole thing.  This helps with plan cache bloat.  I have a lot of systems that use prepared statements, and Kalen says we simulate those calls by using sp_executesql.  Cool! Paul did a series of posts last year to debunk various myths and misconceptions around SQL Server.  He continues to debunk things via “DBA Mythbusters”.  You can get a PDF of a bunch of these here.  One of the myths he went over is the number of tempdb data files that you should have.  Back in 2000, the recommendation was to have as many tempdb data files as there are CPU cores on your server.  This no longer holds true due to the numerous cores we have on our servers.  Paul says you should start out with 1/4 to 1/2 the number of cores and work your way up from there.  BUT!  Paul likes what Bob Ward (twitter) says on this topic: 8 or less cores –> set number of files equal to the number of cores Greater than 8 cores –> start with 8 files and increase in blocks of 4 One common myth out there is to set your MAXDOP to 1 for an OLTP workload with high CXPACKET waits.  Instead of that, dig deeper first.  Look for missing indexes, out-of-date statistics, increase the “cost threshold for parallelism” setting, and perhaps set MAXDOP at the query level.  Paul stressed that you should not plan a backup strategy but instead plan a restore strategy.  What are your recoverability requirements?  Once you know that, now plan out your backups. As Paul always does, he talked about DBCC CHECKDB.  He said how fabulous it is.  I didn’t want to interrupt the presentation, so after his session had ended, I asked Paul about the need to run DBCC CHECKDB on your mirror systems.  You could have data corruption occur at the mirror and not at the principal server.  If you aren’t checking for data corruption on your mirror systems, you could be failing over to a corrupt database in the case of a disaster or even a planned failover.  You can’t run DBCC CHECKDB against the mirrored database, but you can run it against a snapshot off the mirrored database.

  • Back in Atlanta! Wed, Feb 9 2011

    - by KKline
    I always enjoy spending time with my friends from Atlanta, as well as meeting folks and making new friends. If you live in the Atlanta area, I hope you'll join me on the evening of Wednesday, February 9th, 2011. Details are at the Atlanta SQL Server user group website . It's common knowledge that I have a terrible memory for many things. However, one of the few things that my memory is usually really good at is remember names & faces (and remembering stories, but that is another story as well)....(read more)

  • Kill all the project files!

    - by jamiet
    Like many folks I’m a keen podcast listener and yesterday my commute was filled by listening to Scott Hunter being interviewed on .Net Rocks about the next version of ASP.Net. One thing Scott said really struck a chord with me. I don’t remember the full quote but he was talking about how the ASP.Net project file (i.e. the .csproj file) is going away. The rationale being that the main purpose of that file is to list all the other files in the project, and that’s something that the file system is pretty good at. In Scott’s own words (that someone helpfully put in the comments): A file that lists files is really redundant when the OS already does this Romeliz Valenciano correctly pointed out on Twitter that there will still be a project.json file however no longer will there be a need to keep a list of files in a project file. I suspect project.json will simply contain a list of exclusions where necessary rather than the current approach where the project file is a list of inclusions. On the face of it this seems like a pretty good idea. I’ve long been a fan of convention over configuration and this is a great example of that. Instead of listing all the files in a separate file, just treat all the files in the directory as being part of the project. Ostensibly the approach is if its in the directory, its part of the project. Simple. Now I’m not an ASP.net developer, far from it, but it did occur to me that the same approach could be applied to the two Visual Studio project types that I am most familiar with, SSIS & SSDT. Like many people I’ve long been irritated by SSIS projects that display a faux file system inside Solution Explorer. As you can see in the screenshot below the project has Miscellaneous and Connection Managers folders but no such folders exist on the file system: This may seem like a minor thing but it means useful Solution Explorer features like Show All Files and Open Folder in Windows Explorer don’t work and quite frankly it makes me feel like a second class citizen in the Microsoft ecosystem. I’m a developer, treat me like one. Don’t try and hide the detail of how a project works under the covers, show it to me. I’m a big boy, I can handle it! Would it not be preferable to simply treat all the .dtsx files in a directory as being part of a project? I think it would, that’s pretty much all the .dtproj file does anyway (that, and present things in a non-alphabetic order – something else that wildly irritates me), so why not just get rid of the .dtproj file? In the case of SSDT the .sqlproj actually does a whole lot more than simply list files because it also states the BuildAction of each file (Build, NotInBuild, Post-Deployment, etc…) but I see no reason why the convention over configuration approach can’t help us there either. Want to know which is the Post-deployment script? Well, its the one called Post-DeploymentScript.sql! Simple! So that’s my new crusade. Let’s kill all the project files (well, the .dtproj & .sqlproj ones anyway). Are you with me? @Jamiet

  • Temporary Tables in Stored Procedures

    - by Paul White
    Ask anyone what the primary advantage of temporary tables over table variables is, and the chances are they will say that temporary tables support statistics and table variables do not. This is true, of course; even the indexes that enforce PRIMARY KEY and UNIQUE constraints on table variables do not have populated statistics associated with them, and it is not possible to manually create statistics or non-constraint indexes on table variables. Intuitively, then, any query that has alternative execution...(read more)

  • SQL Server 2008 R2: StreamInsight changes at RTM: Access to grouping keys via explicit typing

    - by Greg Low
    One of the problems that existed in the CTP3 edition of StreamInsight was an error that occurred if you tried to access the grouping key from within your projection expression. That was a real issue as you always need access to the key. It's a bit like using a GROUP BY in TSQL and then not including the columns you're grouping by in the SELECT clause. You'd see the results but not be able to know which results are which. Look at the following code: var laneSpeeds = from e in vehicleSpeeds group e...(read more)

  • Andrejus Keeps Cranking Out the Tips

    - by steve.muench
    I've been working on designing and implementing a new set of features for an upcoming Oracle ADF release for the past several months (and several more to come) and this has put a real limit on the time I have available for helping external customers and internal teams, as well as the time I have for blogging. Thankfully, the ADF community at large has many other voices they can listen to for tips and techniques. One I wanted to highlight specifically today is Andrejus Baranovskis' blog, which is steadily building up a high-quality archive of downloadable ADF examples based on his real-world consulting experiences, each with a corresponding explanatory article. If you're not already subscribed to Andrejus' blog, I highly recommend it. Keep up the great work, Andrejus!

  • PASS By-Law Changes

    Over the past year, the PASS Board of Directors (BoD) has been looking at changing the by-laws. We've had in-depth in-person discussions about how the by-laws could/should be changed. Here is the link to the documents that I am referring to: http://www.sqlpass.org/Community/PASSBlog/entryid/300/Amendments-to-PASS-Bylaws.aspx One of the changes that I believe addresses more perception than reality is the rule of "No more than two from a single organization".

  • A tour of the GlassFish 3.1.2 DCOM support

    - by alexismp
    While we've mentioned the DCOM support in GlassFish 3.1.2 several times before, you'll probably find Byron's DCOM blog entry to be useful if you're using Windows as a deployment platform for your GlassFish cluster. Byron discusses how DCOM is used to communicate with remote Windows nodes participating in a GlassFish cluster, what Java libraries were used to wrap around DCOM, what new asadmin commands were addd (in particular validate-dcom) as well as some tips to make this all work on your specific environment. In addition to this blog post, you should considering reading the official product documentation : • Considerations for Using DCOM for Centralized Administration • Setting Up DCOM and Testing the DCOM Set Up

  • Working with Reporting Services Filters – Part 3: The TOP and BOTTOM Operators

    - by smisner
    Thus far in this series, I have described using the IN operator and the LIKE operator. Today, I’ll continue the series by reviewing the TOP and BOTTOM operators. Today, I happened to be working on an example of using the TOP N operator and was not successful on my first try because the behavior is just a bit different than we find when using an “equals” comparison as I described in my first post in this series. In my example, I wanted to display a list of the top 5 resellers in the United States for AdventureWorks, but I wanted it based on a filter. I started with a hard-coded filter like this: Expression Data Type Operator Value [ResellerSalesAmount] Float Top N 5 And received the following error: A filter value in the filter for tablix 'Tablix1' specifies a data type that is not supported by the 'TopN' operator. Verify that the data type for each filter value is Integer. Well, that puzzled me. Did I really have to convert ResellerSalesAmount to an integer to use the Top N operator? Just for kicks, I switched to the Top % operator like this: Expression Data Type Operator Value [ResellerSalesAmount] Float Top % 50 This time, I got exactly the results I expected – I had a total of 10 records in my dataset results, so 50% of that should yield 5 rows in my tablix. So thinking about the problem with Top N some  more, I switched the Value to an expression, like this: Expression Data Type Operator Value [ResellerSalesAmount] Float Top N =5 And it worked! So the value for Top N or Top % must reflect a number to plug into the calculation, such as Top 5 or Top 50%, and the expression is the basis for determining what’s in that group. In other words, Reporting Services will sort the rows by the expression – ResellerSalesAmount in this case – in descending order, and then filter out everything except the topmost rows based on the operator you specify. The curious thing is that, if you’re going to hard-code the value, you must enter the value for Top N with an equal sign in front of the integer, but you can omit the equal sign when entering a hard-coded value for Top %. This experience is why working with Reporting Services filters is not always intuitive! When you use a report parameter to set the value, you won’t have this problem. Just be sure that the data type of the report parameter is set to Integer. Jessica Moss has an example of using a Top N filter in a tablix which you can view here. Working with Bottom N and Bottom % works similarly. You just provide a number for N or for the percentage and Reporting Services works from the bottom up to determine which rows are kept and which are excluded.

  • REPLACENULL in SSIS 2012

    - by Davide Mauri
    While preparing my slides e demos for the forthcoming SQL Server Conference 2012 in Italy, I’ve come across a nice addition to DTS Expression language which I never noticed before and that seems unknown also to the blogosphere: REPLACENULL. REPLACENULL is the same of ISNULL in T-SQL. It’s *very* useful especially when loading a fact table of your BI solution when you need to replace unexisting reference to dimension with dummy values. Here’s an example of how it can be used (please notice that in this example I’m NOT loading a fact table): I’ve noticed that the feature was requested by fellow MVP John Welch http://connect.microsoft.com/SQLServer/feedback/details/636057/ssis-add-a-replacenull-function-to-the-expression-language So: Thanks John and Thanks SSIS Team ! Ah, btw, the Help online is here http://msdn.microsoft.com/en-us/library/hh479601(v=sql.110).aspx Enjoy!

    Last summer I set up Change Data Capture for a client to track changes to their application database to apply those changes to their data warehouse. The client had some issues a short while back and felt they needed to increase the retention period from the default 3 days to 5 days. I ran this query to make that change: sp_cdc_change_job @job_type='cleanup', @retention=7200 The value 7200 represents the number of minutes in a period of 5 days.

    - by merrillaldrich
    Once you get past the basic architecture of a SCOM implementation, and build the servers, and so on, the first real problem is … well, noise. Suddenly (depending on how you deploy) the system will reach out, like marching army ants or a some very clever cybernetic spider and find, and then proceed to yell at you about, every single problem on every server you didn’t know you had. That, of course, is the point. Still, a tool like this is not useful if it doesn’t surface the real problems from the...(read more)
