  • Messages do not always appear in [catalog].[event_messages] in the order that they occur [SSIS]

    - by jamiet
    This is a simple heads up for anyone doing SQL Server Integration Services (SSIS) development using SSIS 2012. Be aware that messages do not always appear in [catalog].[event_messages] in the order that they occur, observe… In the following query I am looking at a subset of messages in [catalog].[event_messages] and ordering them by [event_message_id]: SELECT [event_message_id],[event_name],[message_time],[message_source_name]FROM   [catalog].[event_messages] emWHERE  [event_message_id] BETWEEN 290972 AND 290982ORDER  BY [event_message_id] ASC--ORDER BY [message_time] ASC Take a look at the two rows that I have highlighted, note how the OnPostExecute event for “Utility GetTargetLoadDatesPerETLIfcName” appears after the OnPreExecute event for “FELC Loop over TargetLoadDates”, I happen to know that this is incorrect because “Utility GetTargetLoadDatesPerETLIfcName” is a package that gets executed by an Execute Package Task prior to the For Each Loop “FELC Loop over TargetLoadDates”: If we order instead by [message_time] then we see something that makes more sense: SELECT [event_message_id],[event_name],[message_time],[message_source_name]FROM   [catalog].[event_messages] emWHERE  [event_message_id] BETWEEN 290972 AND 290982--ORDER BY [event_message_id] ASCORDER  BY [message_time] ASC We can see that the OnPostExecute for “Utility GetTargetLoadDatesPerETLIfcName” did indeed occur before the OnPreExecute event for “FELC Loop over TargetLoadDates”, they just did not get assigned an [event_message_id] in chronological order. We can speculate as to why that might be (I suspect the explanation is something to do with the two executables appearing in different packages) but the reason is not the important thing here, just be aware that you should be ordering by [message_time] rather than [event_message_id] if you want to get 100% accurate insights into your executions. @Jamiet

  • PASS: Budget Status

    - by Bill Graziano
    Our budget situation is a little different this year than in years past.  We were late getting an initial budget approved.  There are a number of different reasons this occurred.  We had different competing priorities and the budget got pushed down the list.  And that’s completely my fault for not making the budget a higher priority and getting it completed on time. That left us with initial budget approval in early August rather than prior to June 30th.  Even after that there were a number of small adjustments that needed to be made.  And one large glaring mistake that needed to be fixed.  We had a typo in the budget that made it through twelve versions of review.  In my defense I can only say that the cell was red so of course it had to be negative!  And that’s one more mistake I can add to my long and growing list of Mistakes I’ll Never Make Again. Last week we passed a revised budget (version 17) with this corrected.  This is the version we’re cleaning up and posting to the web site this week or next.

  • Speakers, Please Check Your Time

    - by AjarnMark
    Woodrow Wilson was once asked how long it would take him to prepare for a 10 minute speech. He replied "Two weeks". He was then asked how long it would take for a 1 hour speech. "One week", he replied. 2 hour speech? "I'm ready right now," he replied.  Whether that is a true story or an urban legend, I don’t really know, but either way, it is a poignant reminder for all speakers, and particularly apropos this week leading up to the PASS Community Summit. (Cross-posted to the PASS Professional Development Virtual Chapter blog #PASSProfDev.) What’s the point of that story?  Simply this…if you have plenty of time to do your presentation, you don’t need to prepare much because it is easy to throw in more and more material to stretch out to your allotted time.  But if you are on a tight time constraint, then it will take significant preparation to distill your talk down to only the essential points. I have attended seven of the last eight North American Summit events, and every one of them has been fantastic.  The speakers are great, the material is timely and relevant, and the networking opportunities are awesome.  And every year, there is one little thing that just bugs me…speakers going over their allotted time.  Why does it bother me so?  Well, if you look at a typical schedule for a Summit, you’ll see that there are six or more sessions going on at the same time, and only 15 minutes to move from one to another.  If you’re trying to maximize your training dollar by attending something during every session time slot, and you don’t want to be the last guy trying to squeeze into the middle of the row, then those 15 minutes can be critical.  All the more so if you need to stop and use the bathroom or if you have to hike to the opposite end of the convention center.  It is really a bad position to find yourself having to choose between learning the last key points of Speaker A who is going over time, and getting over to Speaker B on time so you don’t miss her key opening remarks. And frankly, I think it is just rude.  Yes, the speakers are the function, after all they are bringing the content that the rest of us are paying to learn.  But it is also an honor to be given the opportunity to speak at a conference like this, and no one speaker is so important that the conference would be a disaster without him.  Speakers know when they submit their abstract, long before the conference, how much time they will have.  It has been the same pattern at the Summit for at least the last eight years.  Program Sessions are 75 minutes long.  Some speakers who have a good track record, and meet other qualifying criteria, are extended an invitation to present a Spotlight Session which is 90 minutes (a 20% increase).  So there really is no excuse.  It’s not like you were promised a 2-hour segment and then discovered when you got here that it was only 75 minutes.  In fact, it’s not like PASS advertised 90-minute sessions for everyone and then a select few were cut back to only 75.  As a speaker, you know well before you get here which type of session you are doing and how long it is, so as a professional, you should plan accordingly. Now you might think that this only happens to rookies, but I’ll tell you that some of the worst offenders are big-name veterans who draw huge attendance numbers for their sessions.  Some attendees blow this off as, “Hey, it’s so-and-so, and I’d stay here for hours and listen to him/her talk.”  To which I would reply, “Then they should have submitted for a pre- or post-conference day-long seminar instead, but don’t try to squeeze your day-long talk into a 90-minute session.”  Now I don’t really believe that these speakers are being malicious or just selfishly trying to extend their time in the spotlight.  I think that most of them are merely being undisciplined and did not trim their presentation sufficiently, or allowed themselves to get off-track (often in a generous attempt to help someone in the audience with a question or problem that really should have been noted for further discussion after the session). So here is my recommendation…my plea, even.  TRIM THE FAT!  Now.  Before it’s too late.  Before you even get on the airplane, take a long, hard look at your presentation and eliminate some of the points that you originally thought you had to make, but in reality are not truly crucial to your main topic.  Delete a few slides.  Test your demos and have them already scripted rather than typing them during your talk.  It is better to cut out too much and end up with plenty of time at the end for Questions & Answers.  And you can always keep some notes on the stuff that you cut out so that you could fill it back in at the end as bonus material if you really do end up with a whole bunch of time on your hands.  But I don’t think you will.  And if you do, that will look even better to the audience as it will look like you’re giving them something extra that not every audience gets.  And they will thank you for that.

  • Can we put percentage on amount of work of a certain role in project's lifecycle?

    - by deviDave
    The title may be confusing, but I will elaborate it here. I am trying to figure our how much time and effort each person spend during some project. I divided roles into: - junior developer (works mainly on UI and some light things) - senior developer (develops complex logic, database structures, etc.) - lead developer (leads the team, usually most experienced person) - negotiator/resolver (a person who directly talk to a client trying to either negotiate terms and timeframe or to clarify vagueness presented by a team leader) My AIM is to calculate percentage of role's involvement based on quality, not time (obviously a junior will spend most time in project, but with the least quality). In the end I would get a table which may look like this: Total: 100% ---------------- Junior: 10% Senior: 50% Lead: 30% Negotiator: 10% Can this be achieved? Has anyone found any source which may help me?

  • How to encourage version control adoption

    - by Man Wa kileleshwa
    I have recently started working in a team where there is no version control. Most of the team members are not used to any kind of version control. I've been using mercurial privately to track my work. I would like to encourage others to adopt it, and at the very least start to version their code as they develop changes. Can anyone give me advice on how I can encourage adoption of a distributed version control such as mercurial. Any advice on how to win people including managers to DVCS would be much appreciated.

  • How are Reads Distributed in a Workload

    - by Bill Graziano
    People have uploaded nearly one millions rows of trace data to TraceTune.  That’s enough data to start to look at the results in aggregate.  The first thing I want to look at is logical reads.  This is the easiest metric to identify and fix. When you upload a trace, I rank each statement based on the total number of logical reads.  I also calculate each statement’s percentage of the total logical reads.  I do the same thing for CPU, duration and logical writes.  When you view a statement you can see all the details like this: This single statement consumed 61.4% of the total logical reads on the system while we were tracing it.  I also wanted to see the distribution of reads across statements.  That graph looks like this: On average, the highest ranked statement consumed just under 50% of the reads on the system.  When I tune a system, I’m usually starting in one of two modes: this “piece” is slow or the whole system is slow.  If a given piece (screen, report, query, etc.) is slow you can usually find the specific statements behind it and tune it.  You can make that individual piece faster but you may not affect the whole system. When you’re trying to speed up an entire server you need to identity those queries that are using the most disk resources in aggregate.  Fixing those will make them faster and it will leave more disk throughput for the rest of the queries. Here are some of the things I’ve learned querying this data: The highest ranked query averages just under 50% of the total reads on the system. The top 3 ranked queries average 73% of the total reads on the system. The top 10 ranked queries average 91% of the total reads on the system. Remember these are averages across all the traces that have been uploaded.  And I’m guessing that people mainly upload traces where there are performance problems so your mileage may vary. I also learned that slow queries aren’t the problem.  Before I wrote ClearTrace I used to identify queries by filtering on high logical reads using Profiler.  That picked out individual queries but those rarely ran often enough to put a large load on the system. If you look at the execution count by rank you’d see that the highest ranked queries also have the highest execution counts.  The graph would look very similar to the one above but flatter.  These queries don’t look that bad individually but run so often that they hog the disk capacity. The take away from all this is that you really should be tuning the top 10 queries if you want to make your system faster.  Tuning individually slow queries will help those specific queries but won’t have much impact on the system as a whole.

  • Fixed Bid vs. T&amp;M &ndash; Take 2

    - by AjarnMark
    One of my most popular blog entries of all time is my Contracting Tips: Fixed Bid vs. T&M post from January, 2004.  This post consistently shows up in my referrers list, usually coming from a search engine.  Recently, Brent Ozar (@BrentO) wrote a great argument for why he always bills by the hour (a.k.a. Time & Materials or T&M) which itself was a response to Mark Richman’s (@mrichman) post on why he never bills by the hour (fixed bid).  Each article has good arguments, and I encourage you to read them both and choose the best approach for you. As for me, my experience parallels Brent’s and I historically have leaned toward the Time & Materials model.

  • low speed web application, Server problem or Application

    - by Ashian
    Hi, I have a web application written by asp.net (c#) sql server 2005. we host it on 2 dedicated server ( IIS and SQL server ) From some month ago , in some days of week we have many reports about speed issue. we have some other application on this server using same database. when we have speed problem all aplication on these server have this problem, but applications on other server in same data center work correctly. ram and cpu usage are ok. how can I check that the problem related to internet connection or my application design? which parameters must be checked. Some other information In applications users can upload several files to server , each file up to 3 MB. we use a sql web admin application, on same server that has same problem, this is a standard application which work perfectly on other servers.

  • How can I refactor a code base while others rapidly commit to it?

    - by Incognito
    I'm on a private project that eventually will become open source. We have a few team members, talented enough with the technologies to build apps, but not dedicated developers who can write clean/beautiful and most importantly long-term maintainable code. I've set out to refactor the code base, but it's a bit unwieldy as someone in the team out in another country I'm not in regular contact with could be updating this totally separate thing. I know one solution is to communicate rapidly or adopt better PM practices, but we're just not that big yet. I just want to clean up the code and merge nicely into what he has updated. Would a branch be a suitable plan? A best-effort-merge? Something else?

  • My new favourite traceflag

    - by Dave Ballantyne
    As we are all aware, there are a number of traceflags.  Some documented, some semi-documented and some completely undocumented.  Here is one that is undocumented that Paul White(b|t) mentioned almost as an aside in one of his excellent blog posts. Much has been written about residual predicates and how a predicate can be pushed into a seek/scan operation.  This is a good thing to happen,  it does save a lot of processing from having to be done.  For the uninitiated though: If we have a simple SELECT statement such as : the process that SQL Server goes through to resolve this is : The index IX_Person_LastName_FirstName_MiddleName is navigated to find the first “Smith” For each “Smith” the middle name is checked for being a null. Two operations!, and the execution plan doesnt fully represent all the work that is being undertaken. As you can see there is only a single seek operation, the work undertaken to resolve the condition “MiddleName is not null” has been pushed into it.  This can be seen in the properties. “Seek predicate” is how the index has been navigated, and “Predicate” is the condition run over every row,  a scan inside a seek!. So the question is:  How many rows have been resolved by the seek and how many by the scan ?  How many rows did the filter remove ? Wouldn’t it be nice if this operation could be split ?  That exactly what traceflag 9130 does. Executing the query: That changes the plan rather dramatically, and should be changing how we think about the index seek itself.  The Filter operator has been added and, unsurprisingly, the condition in this is “MiddleName is not null” So it is now evident that the seek operation found 103 Smiths and 60 of those Smiths had a non-null MiddleName. This traceflag has no place on a production system,  dont even think about it

    I am happy to announce the release of DotNetNuke 5.4.1 which corrects the major issues which slipped through the QA process for 5.4. While we try to do a good job in testing our releases, our recent efforts for 5.3 and 5.4 have fallen short of the mark. We are currently working with a small team of commercial module developers and the core team to put a better public beta testing process in place that will help augment our own internal testing. Ultimately, community testing is the only testing that...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Why do some open source projects do not allow to report issues in a public issue tracker?

    - by linquize
    Why do some open source projects do not allow to report issues in a public issue tracker? Those projects requires the issues to be reported via email, and the issues may be forwarded to people in mailing list. Users may repeatedly report the same issue if there is no public issue tracker, as they have no easy way to know what have been reported before. The project team members need to spend extra time answering those repeated issues. Some projects do have a public issue tracker, but the issues are still reported through email and they are posted only by the project team only after filtering. It does not allow anyone to report directly in issue tracker. (example: SVN) Such arrangement is not transparent nor open, which I think it violates the philosophy of open source. And it is outdated.

  • Join me to register for the Summit

    - by Bill Graziano
    This year the Summit registration opens at 6PM on Sunday at the Seattle convention center.  Last year we had a dozen people hanging out, watching the twitter feed on the big monitor and catching up.  All we really needed was a bar and we’d have our own little party going. So this year I’m adding a bar.  I’ve arranged for a cash bar and some stand up tables.  I’m buying the first round for the first 40 or so people that come by.  Come by, register and say Hi.  I’d especially like to encourage first-time attendees to stop by.  This is a low key way to meet some people that will be at the conference.

  • Useful git commit messages for merged branches

    - by eykanal
    As a follow-up to this question: If I'm working on a team by myself, I can maintain useful commit messages when merging branches by squashing all the commits to a single diff and then merging that diff. That way I can easily see what changes were introduced in the branch, and I have a single summary describing the feature/change/whatever that was accomplished in that branch when browsing the master branch. My question now is, how can I accomplish this when working with a team? In that situation, the branches will be pushed to a remote repository, meaning that I can't squash all the commits in the branch down to a single commit. If the branch is public, can I still have a single useful merge commit in the master branch? (By "useful" I mean that the commit in the master line tells me (1) a useful summary of what was done in the branch and (2) diffs of the same.)

  • TechEd North America 2012–Day 3 #msTechEd #teched

    - by Marco Russo (SQLBI)
    Yesterday I spent the longest day at this TechEd: we talked with many people at Community Night until 9pm and I have to say that just a few months after Analysis Services 2012 has been released, there are many people already using it. And the adoption of PowerPivot is starting to be quite large. Many new ideas and challenging coming from several different real world scenarios. I was tired but really happy. Alberto presented his Many-to-Many Relationships in BISM Tabular session that was in the same time slot of the BI Power Hour. For this reason, very few people attended Alberto’s session so I think many will watch the recorded session (it should be available within a few days). So what about today? I’ll spend some time at Technical Learning Center area (full schedule here) but the most important event today will be the Querying multi-billion rows with many to many relationships in SSAS Tabular (xVelocity) at the Private Cloud, Public Cloud and Data Platform Theater in the Technical Learning Center area (next to the SQL Server 2012 zone).  Why you should attend? Mainly because you will see live demo over 4 billion rows table with many-to-many relationships involved in complex queries. But for those of you that think this is not enough to attend a 15 minute funny session, well, we’ll give away some 8GB USB Memory Keys to those of you that will guess exact response time of queries before execution. Convinced? Join us at 11:15am and don’t be late, the session will finish at 11:30am! After that, we’ll run a book signing session at the Bookstore at 12:30pm and I will be in the Technical Learning Center area at 3:00pm until 5:00pm. See you there!

  • Update server version for postgres 9.1.2

    - by Nai
    I'm trying to run a postgis sql script and I'm running into the following error. Am I correct to say that updating my server version will fix it? If so, how can I go about updating it? I'm on Mac OSX Lion and installed Postgres via brew. Apparently I have an older version installed which is 9.1.2 but installing postgis installed postgres 9.2.1 on to my system. How can I point my postgres server to the new one? nai@nyc /usr/local/share/postgis (git::master) $ psql -d template_postgis -f postgis.sql SET BEGIN psql:postgis.sql:49: ERROR: incompatible library "/usr/local/Cellar/postgresql/9.2.1/lib/postgis-2.0.so": version mismatch DETAIL: Server is version 9.1, library is version 9.2. nai@nyc /usr/local/share/postgis (git::master) $ psql psql (9.2.1, server 9.1.2) WARNING: psql version 9.2, server version 9.1. Some psql features might not work.

  • Feedback from SQLBits 8

    - by Peter Larsson
    This years SQLBits occurred in Brighton. Although I didn’t have the opportunity to attend the full conference, I did a presentation at Saturday. Getting to Brighton was easy. Drove to Copenhagen airport at 0415, flew 0605 and arrived at Gatwick 0735. Then I took the direct train to Brighton and showed up at 0830, just one hour before presenting. This was the easy part. Getting home was much worse. Presentation ended at 1030 and I had to rush to the train station to get back to London, change to tube for Heathrow. Made it at the gate just 15 seconds before closing. That included a half mile run in the airport… Anyway, yesterday I got the feedback for my presentation. It does look good, especially since English is not my first language. This is the first graph Seems to be just halfway between conference average and best session. I can live with that. Second graph shows more detail about attendees voting. It also look acceptable. A wider spread for the 9’s, but it is an inevitable effect from how attendees percept the session. I did get a lot of 8’s and the lower grades in an descending order. The two people voting 4 and 5 didn’t say why they voted this so I don’t know how to remedy this. Third graph is about each category of votes.   Again, I find this acceptable. The Session abstract and Speaker’s knowledge seems to follow attendees expectations compared to conference average. I seem to have met the attendees expectations (and some more) for the other four categories, also compared to conference average. Since this did encourage me, I believe I will present some more at future meetings. I do have a new presentation about something all developers are doing every day but they may not know it. I will also cover this new topic in the next Deep Dives II book. Stay tuned! //Peter
