  • SQL SERVER – Backing Up and Recovering the Tail End of a Transaction Log – Notes from the Field #042

    - by Pinal Dave
    [Notes from Pinal]: The biggest challenge which people face is not taking backup, but the biggest challenge is to restore a backup successfully. I have seen so many different examples where users have failed to restore their database because they made some mistake while they take backup and were not aware of the same. Tail Log backup was such an issue in earlier version of SQL Server but in the latest version of SQL Server, Microsoft team has fixed the confusion with additional information on the backup and restore screen itself. Now they have additional information, there are a few more people confused as they have no clue about this. Previously they did not find this as a issue and now they are finding tail log as a new learning. Linchpin People are database coaches and wellness experts for a data driven world. In this 42nd episode of the Notes from the Fields series database expert Tim Radney (partner at Linchpin People) explains in a very simple words, Backing Up and Recovering the Tail End of a Transaction Log. Many times when restoring a database over an existing database SQL Server will warn you about needing to make a tail end of the log backup. This might be your reminder that you have to choose to overwrite the database or could be your reminder that you are about to write over and lose any transactions since the last transaction log backup. You might be asking yourself “What is the tail end of the transaction log”. The tail end of the transaction log is simply any committed transactions that have occurred since the last transaction log backup. This is a very crucial part of a recovery strategy if you are lucky enough to be able to capture this part of the log. Most organizations have chosen to accept some amount of data loss. You might be shaking your head at this statement however if your organization is taking transaction logs backup every 15 minutes, then your potential risk of data loss is up to 15 minutes. Depending on the extent of the issue causing you to have to perform a restore, you may or may not have access to the transaction log (LDF) to be able to back up those vital transactions. For example, if the storage array or disk that holds your transaction log file becomes corrupt or damaged then you wouldn’t be able to recover the tail end of the log. If you do have access to the physical log file then you can still back up the tail end of the log. In 2013 I presented a session at the PASS Summit called “The Ultimate Tail Log Backup and Restore” and have been invited back this year to present it again. During this session I demonstrate how you can back up the tail end of the log even after the data file becomes corrupt. In my demonstration I set my database offline and then delete the data file (MDF). The database can’t become more corrupt than that. I attempt to bring the database back online to change the state to RECOVERY PENDING and then backup the tail end of the log. I can do this by specifying WITH NO_TRUNCATE. Using NO_TRUNCATE is equivalent to specifying both COPY_ONLY and CONTINUE_AFTER_ERROR. It as its name says, does not try to truncate the log. This is a great demo however how could I achieve backing up the tail end of the log if the failure destroys my entire instance of SQL and all I had was the LDF file? During my demonstration I also demonstrate that I can attach the log file to a database on another instance and then back up the tail end of the log. If I am performing proper backups then my most recent full, differential and log files should be on a server other than the one that crashed. I am able to achieve this task by creating new database with the same name as the failed database. I then set the database offline, delete my data file and overwrite the log with my good log file. I attempt to bring the database back online and then backup the log with NO_TRUNCATE just like in the first example. I encourage each of you to view my blog post and watch the video demonstration on how to perform these tasks. I really hope that none of you ever have to perform this in production, however it is a really good idea to know how to do this just in case. It really isn’t a matter of “IF” you will have to perform a restore of a production system but more of a “WHEN”. Being able to recover the tail end of the log in these sever cases could be the difference of having to notify all your business customers of data loss or not. If you want me to take a look at your server and its settings, or if your server is facing any issue we can Fix Your SQL Server. Note: Tim has also written an excellent book on SQL Backup and Recovery, a must have for everyone.

  • What is Happening vs. What is Interesting

    - by Geertjan
    Devoxx 2011 was yet another confirmation that all development everywhere is either on the web or on mobile phones. Whether you looked at the conference schedule or attended sessions or talked to speakers at any point at all, it was very clear that no development whatsoever is done anymore on the desktop. In fact, that's something Tim Bray himself told me to my face at the speakers dinner. No new developments of any kind are happening on the desktop. Everyone who is currently on the desktop is working overtime to move all of their applications to the web. They're probably also creating a small subset of their application on an Android tablet, with an even smaller subset on their Android phone. Then you scratch that monolithic surface and find some interesting results. Without naming any names, I asked one of these prominent "ah, forget about the desktop" people at the Devoxx speakers dinner (and I have a witness): "Yes, the desktop is dead, but what about air traffic control, stock trading, oil analysis, risk management applications? In fact, what about any back office application that needs to be usable across all operating systems? Here there is no concern whatsoever with 100% accessibility which is, after all, the only thing that the web has over the desktop, (except when there's a network failure, of course, or when you find yourself in the 3/4 of the world where there's bandwidth problems)? There are 1000's of hidden applications out there that have processing requirements, security requirements, and the requirement that they'll be available even when the network is down or even completely unavailable. Isn't that a valid use case and aren't there 1000's of applications that fall into this so-called niche category? Are you not, in fact, confusing consumer applications, which are increasingly web-based and mobile-based, with high-end corporate applications, which typically need to do massive processing, of one kind or another, for which the web and mobile worlds are completely unsuited?" And you will not believe what the reply to the above question was. (Again, I have a witness to this discussion.) But here it is: "Yes. But those applications are not interesting. I do not want to spend any of my time or work in any way on those applications. They are boring." I'm sad to say that the leaders of the software development community, including those in the Java world, either share the above opinion or are led by it. Because they find something that is not new to be boring, they move on to what is interesting and start talking like the supposedly-boring developments don't even exist. (Kind of like a rapper pretending classical music doesn't exist.) Time and time again I find myself giving Java desktop development courses (at companies, i.e., not hobbyists, or students, but companies, i.e., the places where dollars are earned), where developers say to me: "The course you're giving about creating cross-platform, loosely coupled, and highly cohesive applications is really useful to us. Why do we never find information about this topic at conferences? Why can we never attend a session at a conference where the story about pluggable cross-platform Java is told? Why do we get the impression that we are uncool because we're not on the web and because we're not on a mobile phone, while the reason for that is because we're creating $1000,000 simulation software which has nothing to gain from being on the web or on the mobile phone?" And then I say: "Because nobody knows you exist. Because you're not submitting abstracts to conferences about your very interesting use cases. And because conferences tend to focus on what is new, which tends to be web related (especially HTML 5) or mobile related (especially Android). Because you're not taking the responsibility on yourself to tell the real stories about the real applications being developed all the time and every day. Because you yourself think your work is boring, while in fact it is fascinating. Because desktop developers are working from 9 to 5 on the desktop, in secure environments, such as banks and defense, where you can't spend time, nor have the interest in, blogging your latest tip or trick, as opposed to web developers, who tend to spend a lot of time on the web anyway and are therefore much more inclined to create buzz about the kind of work they're doing." So, next time you look at a conference program and wonder why there's no stories about large desktop development projects in the program, here's the short answer: "No one is going to put those items on the program until you start submitting those kinds of sessions. And until you start blogging. Until you start creating the buzz that the web developers have been creating around their work for the past 10 years or so. And, yes, indeed, programmers get the conference they deserve." And what about Tim Bray? Ask yourself, as Google's lead web technology evangelist, how many desktop developers do you think he talks to and, more generally, what his frame of reference is and what, clearly, he considers to be most interesting.

  • SOLVED BleachBit: How to Completely Clear URL History in Firefox?

    - by tSquirrel
    14.04 / Firefox 29.0 I've been using Bleachbit to clear usage/file history, and for the most part it works great. However, it doesn't seem to clear the website hostnames out of the URL, at all. These addresses are not bookmarked. Also, the total URL isn't preserved, just the hostname. Visit site http://www.bluesnews.com/some_random_URL_string Exit Firefox Run Bleachbit, with ALL Firefox options selected Restart Firefox Check history: completely empty, other than bookmarked sites. www.bluesnews is NOT bookmarked Type "blue" which is Firefox automatically completes as "http://www.bluesnews.com/" Alternate Step #3: Use Firefox's built-in "Clear History" and select ALL entries with a time frame of "Everything". Same result as above. My inquiry in BB forums hasn't been responded to. I found Dan's proposed solution, however changing autocomplete in about:config only turns off the function, it doesn't actually stop storing URLs. SOLVED - See my comment in the "Answer" response from Tim

  • Is IE9 a modern browser?

    - by TATWORTH
    At http://people.mozilla.com/~prouget/ie9/ there is a very provocative article entitled "Is IE9 a modern browser?". There is a rebuttal by Tim Sneath at http://blogs.msdn.com/b/tims/archive/2011/02/15/a-modern-browser.aspx that is well worth a look. Certainly IE9 is already superior to its predecessors. My comment on the matter is that those that consider IE9 to be non-standards compliant, should submit tests to the W3C to demonstrate the non-compliance. Upon acceptance by the W3C, all the competing browsers can then be re-tested. I prefer objective tests to subjective opinion. I have used IE9 and on some sites such as Hotmail, it is noticeably faster. I have so far been unable to apply the promised IE9 lockout of spyware cookies. With Firefox, I just instal NoScript and never enable spyware sites.

  • Steve Jobs quitte la direction d'Apple pour raisons médicales, les actions de la compagnie chutent déjà suite à cette annonce

    Steve Jobs quitte la direction d'Apple pour raisons médicales, les actions de la compagnie accusent déjà des chutes en bourse suite à cette annonce C'est une information un peu grand public qui aurait plutôt sa place dans un journal people, mais au vu de la tonne d'encre qu'elle a déjà fait couler en moins de 24 heures, il me semblait important de la relayer. D'autant plus qu'elle en inquiète très sévèrement certains. Steve Jobs, le patron d'Apple, vient en effet d'annoncer qu'il se retirait momentanément de la direction opérationnelle d'Apple. Si l'homme en reste néanmoins CEO et impliqué dans les "décisions stratégiques majeures" à venir, il a délégué une grande partie de ses responsabilités à Tim Cook, comme cel...

  • Ubuntu Software Center is crashing while trying to install psychonauts

    I am having a problem installing Tim Schafers epic platform video game Psychonauts trough the Ubuntu Software Center. I have bought the game on http://www.humblebundle.com/ and I have used the new redeem option introduced in this bundle: "redeem your bundle on the Ubuntu Software Center." When I have downloaded approximately 2.1 GB of Psychonauts then Ubuntu Software Center starts to repeatedly crash and pop-up with a new crash report dialog every few seconds (before previous ones are closed and that will crash the computer after a few min, unless I stop the download). I also have a file-size bug, where Ubuntu Software Center tells me that I have downloaded 880,2 MB out of 133,3 MB I use the new Ubuntu 12.04 LTS and Ubuntu Software Center version 5.2.2.2 (©2009-2011 Canonical <--- That is also a bug, should be 2012 I guess) I hope someone can help me.
