  • Yes, you can benefit from both data and backup compression

    - by AaronBertrand
    Earlier today, MSSQLTips posted a backup compression tip by Thomas LaRock ( blog | twitter ). In that article, Tom states: "If you are already compressing data then you will not see much benefit from backup compression." I don't want to argue with a rock star, and I will concede that he may be right in some scenarios. Nonetheless, I tweeted that "it depends;" Thomas then asked for "an example where you have data comp and you also see a large benefit from backup comp?" My initial reaction came about...(read more)

  • PeopleSoft at Alliance 2012 Executive Forum

    - by John Webb
    Guest Posting From Rebekah Jackson This week I jointed over 4,800 Higher Ed and Public Sector customers and partners in Nashville at our annual Alliance conference.   I got lost easily in the hallways of the sprawling Gaylord Opryland Hotel. I carried the resort map with me, and I would still stand for several minutes at a very confusing junction, studying the map and the signage on the walls. Hallways led off in many directions, some with elevators going down here and stairs going up there. When I took a wrong turn I would instantly feel stuck, lose my bearings, and occasionally even have to send out a call for help.    It strikes me that the theme for the Executive Forum this year outlines a less tangible but equally disorienting set of challenges that our higher education customer’s CIOs are facing: Making Decisions at the Intersection of Business Value, Strategic Investment, and Enterprise Technology. The forces acting upon higher education institutions today are not neat, straight-forward decision points, where one can glance to the right, glance to the left, and then quickly choose the best course of action. The operational, technological, and strategic factors that must be considered are complex, interrelated, messy…and the stakes are high. Michael Horn, co-author of “Disrupting Class: How Disruptive Innovation Will Change the Way the World Learns”, set the tone for the day. He introduced the model of disruptive innovation, which grew out of the research he and his colleagues have done on ‘Why Successful Organizations Fail’. Highly simplified, the pattern he shared is that things start out decentralized, take a leap to extreme centralization, and then experience progressive decentralization. Using computers as an example, we started with a slide rule, then developed the computer which centralized in the form of mainframes, and gradually decentralized to mini-computers, desktop computers, laptops, and now mobile devices. According to Michael, you have more computing power in your cell phone than existed on the planet 60 years ago, or was on the first rocket that went to the moon. Applying this pattern to Higher Education means the introduction of expensive and prestigious private universities, followed by the advent of state schools, then by community colleges, and now online education. Michael shared statistics that indicate 50% of students will be taking at least one on line course by 2014…and by some measures, that’s already the case today. The implication is that technology moves from being the backbone of the campus, the IT department’s domain, and pushes into the academic core of the institution. Innovative programs are underway at many schools like Bellevue and BYU Idaho, joined by startups and disruptive new players like the Khan Academy.   This presents both threat and opportunity for higher education institutions, and means that IT decisions cannot afford to be disconnected from the institution’s strategic plan. Subsequent sessions explored this theme.    Theo Bosnak, from Attain, discussed the model they use for assessing the complete picture of an institution’s financial health. Compounding the issue are the dramatic trends occurring in technology and the vendors that provide it. Ovum analyst Nicole Engelbert, shared her insights next and suggested that incremental changes are no longer an option, instead fundamental changes are affecting the landscape of enterprise technology in higher ed.    Nicole closed with her recommendation that institutions focus on the trends in higher education with an eye towards the strategic requirements and business value first. Technology then is the enabler.   The last presentation of the day was from Tom Fisher, Sr. Vice President of Cloud Services at Oracle. Tom runs the delivery arm of the Cloud Services group, and shared his thoughts candidly about his experiences with cloud deployments as well as key issues around managing costs and security in cloud deployments. Okay, we’ve covered a lot of ground at this point, from financials planning, business strategy, and cloud computing, with the possibility that half of the institutions in the US might not be around in their current form 10 years from now. Did I forget to mention that was raised in the morning session? Seems a little hard to believe, and yet Michael Horn made a compelling point. Apparently 100 years ago, 8 of the top 10 education institutions in the world were German. Today, the leading German school is ranked somewhere in the 40’s or 50’s. What will the landscape be 100 years from now? Will there be an institution from China, India, or Brazil in the top 10? As Nicole suggested, maybe US parents will be sending their children to schools overseas much sooner, faced with the ever-increasing costs of a US based education. Will corporations begin to view skill-based certification from an online provider as a viable alternative to a 4 year degree from an accredited institution, fundamentally altering the education industry as we know it?

  • 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.

  • mysql join with multiple values in one column

    - by CYREX
    I need to make a query that creates 3 columns that come from 2 tables which have the following relations: TABLE 1 has Column ID that relates to TABLE 2 with column ID2 In TABLE 1 there is a column called user In TABLE 2 there is a column called names There can be 1 unique user but there can be many names associated to that user. If i do the following i get all data BUT the user column repeats itself for each name it has associated. What i want is for use to appear unique but the names columns appear with all the names associated to the user column but separated by commas, like the following: select user,names from TABLE1 left join TABLE2 on TABLE1.id = TABLE2.id This will show the users repeated everytime a name appears for that user. what i want is to appear like this: USER - NAMES cyrex - pedrox, rambo, zelda homeboy - carmen, carlos, tom, sandra jerry - seinfeld, christine ninja - soloboy etc....

    La qualité de la recherche en ligne est-elle subjective ? Bing serait meilleur que Google d'après Search Engine Land Un manager marketing travaillant pour Search Engine Land, Conrad Saam, a lancé vingt recherches sur Bing et sur Google. A chaque fois, il envoyait des requêtes évitant les demandes les plus simples (comme trouver le site Internet d'une grosse société par exemple) et mélangeant plusieurs mots. Il a ainsi demandé aux deux moteurs de recherche de lui trouver des occurrences pour "l'avocat Tom Brady".

  • Open GL Android frame-by-frame animation tutorial/example code

    - by Trick
    My first question was asked wrong, so I need to ask again :) I found out, that I will have to do an OpenGL animation for my Android game. The closest (known) example is Talking Tom (but I don't know how they did the animations). I have large PNGs which I would like to put into a animation. For example - 30 PNGs 427×240px at 8 FPS. I know some things already about Open GL, but I am used to learn from example code. And it is quicker that way (so I don't need to invent hot water all over again :)). Does anybody has any points to direct me?

  • Does my JavaScript look big in this?

    - by benhowdle89
    As programmers, you have certain curtains to hide behind with your code. With PHP all of your code is server side preprocessed, so this never see's the light of day as far as the user is concerned. If you have maybe rushed through some code for a deadline, as long as it functions correctly then the user never needs to know how many expletives you've inserted into the comments. However with more and more applications being written for the web, with a desktop feel implemented by AJAX and popular frameworks like jQuery being banded around to every Tom, Dick and Harry, how can a programmer maintain some dignity and hide his/her JavaScript code without it being flaunted like dirty laundry when the users hit Right Click-View Source or Inspect Element. Are there any ways to hide JavaScript application logic/code?

BPM is as much about people as it is about technology. As people adopt new ways of engagement, new channels of communications and new devices to interact , the changes are reflected in BPM practices. As Social and Mobile have become an integral part of our personal and professional lives, we’ll see tighter integration of social and mobile with BPM, and more use cases emerging for smarter process management in 2013. And with products and services becoming less differentiated, organizations will strive to differentiate on Customer Experience. Concepts like Pace Layered Architecture and Dynamic Case Management will provide more flexibility and agility to IT groups and knowledge workers. Take a look at some of these capabilities we showcased (see video) at Oracle OpenWorld 2012. Some of these trends that will continue to gain momentum in 2013: Social networks and social media have provided a new way for businesses to engage with customers. A prospect is likely to reach out to their social network before making any purchase. Companies are increasingly engaging with customers in social networks to influence their purchasing decisions, as well as listening to customers via tools like sentiment analysis to see what customers think about a particular product or process. These insights are valuable as companies look to improve their processes. Inside organizations, workers are using social tools to engage with each other to design new products and processes. Social collaboration tools are being used to resolve issues where an employee needs consultation to reach a decision. Oracle BPM Suite includes social interaction as an integral part of its process design and work management to empower today’s business users. Ubiquitous smart mobile devices are trending as a tool of choice for many workers. Many companies are adopting the policy of “Bring Your Own Device,” and the device of choice is a tablet. Devices like smart phones and tablets not only provide mobility to workers and customers, but they also provide additional important information – the context. By integrating the mobile context (location, photos, and preferences) into your processes, organizations can make much more informed decisions, as well as offer more personalized service to customers. Using Oracle ADF Mobile, you can easily create user interfaces for mobile devices and also capture location data for process execution. Customer experience was at the forefront of trending topics in 2012. Organizations are trying to understand their customers better and offer them more personalized and differentiated services. Customer experience is paramount when companies design sales and support processes. Companies are looking to BPM to consistently and efficiently orchestrate customer facing processes across disparate systems, departments and channels of communication. Oracle BPM Suite provides just the right capabilities for organizations to design and deliver an excellent customer experience. Pace Layered Architecture strategy is gaining traction as a way to maximize agility and minimize disruption in organizations. It provides a framework to manage the evolution of your information system when different pieces of it are changing at different rates and need to be updated independent of one another. Oracle Fusion Middleware and Oracle BPM Suite are designed with this in mind. The database layer, integration layer, application layer, and process layer should not be required to change at the same time. Most of the business changes to policy or process can be done at the process layer without disrupting the whole infrastructure. By understanding the type of change needed at a particular level, organizations can become much more agile and efficient. Adaptive Case Management proposes more flexibility to manage processes or cases that do not follow a structured process flow. In such situations, the knowledge worker managing the case needs to evaluate what step should occur next because the sequence of steps can’t be predetermined. Another characteristic is that it requires much more collaboration than straight-through process. As simple processes become automated, and customers adopt more and more self-service, cases that reach the case workers are much more complex and need more investigation. Oracle BPM suite includes comprehensive adaptive case management capability to manage such unstructured and complex processes. Smart BPM or making your BPM intelligent has been the holy grail for BPM practitioners who imagined that one day BPM would become one with Business Intelligence, Business Activity Monitoring and Complex Event Processing, making it much more responsive and helpful in organizational decision making. In 2013, organizations will begin to deploy these intelligent BPM solutions. Oracle offers an integrated solution that brings together the powerful functionality of BI, BAM, event processing, and Real Time Decisions to help organizations create smart process based solutions. In order to help customers reach their BPM goals faster and remove risks associated with BPM initiatives, Oracle has introduced Oracle Process Accelerators, pre-built best practices applications built on Oracle BPM Suite that are fully production grade and ready to deploy. These are exiting times for BPM practitioners and there is so much to look forward to in 2013. We wish you a very happy and prosperous New Year 2013. Happy BPMing!

(Select the mysql-cluster-7.3-labs-June-2012 build) In this blog, I will attempt to discuss the design rationale, implementation, configuration and steps to get started in evaluating the first MySQL Cluster 7.3 Labs Release. Pace of Innovation It was only a couple of months ago that we announced the General Availability (GA) of MySQL Cluster 7.2, delivering 1 billion Queries per Minute, with 70x higher cross-shard JOIN performance, Memcached NoSQL key-value API and cross-data center replication.  This release has been a huge hit, with downloads and deployments quickly reaching record levels. The announcement of the first MySQL Cluster 7.3 Early Access lab release at today's MySQL Innovation Day event demonstrates the continued pace in Cluster development, and provides an opportunity for the community to evaluate and feedback on new features they want to see. What’s the Plan for MySQL Cluster 7.3? Well, Foreign Keys, as you may have gathered by now (!), and this is the focus of this first Labs Release. As with MySQL Cluster 7.2, we plan to publish a series of preview releases for 7.3 that will incrementally add new candidate features for a final GA release (subject to usual safe harbor statement below*), including: - New NoSQL APIs; - Features to automate the configuration and provisioning of multi-node clusters, on premise or in the cloud; - Performance and scalability enhancements; - Taking advantage of features in the latest MySQL 5.x Server GA. Design Rationale MySQL Cluster is designed as a “Not-Only-SQL” database. It combines attributes that enable users to blend the best of both relational and NoSQL technologies into solutions that deliver web scalability with 99.999% availability and real-time performance, including: Concurrent NoSQL and SQL access to the database; Auto-sharding with simple scale-out across commodity hardware; Multi-master replication with failover and recovery both within and across data centers; Shared-nothing architecture with no single point of failure; Online scaling and schema changes; ACID compliance and support for complex queries, across shards. Native support for Foreign Key constraints enables users to extend the benefits of MySQL Cluster into a broader range of use-cases, including: - Packaged applications in areas such as eCommerce and Web Content Management that prescribe databases with Foreign Key support. - In-house developments benefiting from Foreign Key constraints to simplify data models and eliminate the additional application logic needed to maintain data consistency and integrity between tables. Implementation The Foreign Key functionality is implemented directly within MySQL Cluster’s data nodes, allowing any client API accessing the cluster to benefit from them – whether using SQL or one of the NoSQL interfaces (Memcached, C++, Java, JPA or HTTP/REST.) The core referential actions defined in the SQL:2003 standard are implemented: CASCADE RESTRICT NO ACTION SET NULL In addition, the MySQL Cluster implementation supports the online adding and dropping of Foreign Keys, ensuring the Cluster continues to serve both read and write requests during the operation. An important difference to note with the Foreign Key implementation in InnoDB is that MySQL Cluster does not support the updating of Primary Keys from within the Data Nodes themselves - instead the UPDATE is emulated with a DELETE followed by an INSERT operation. Therefore an UPDATE operation will return an error if the parent reference is using a Primary Key, unless using CASCADE action, in which case the delete operation will result in the corresponding rows in the child table being deleted. The Engineering team plans to change this behavior in a subsequent preview release. Also note that when using InnoDB "NO ACTION" is identical to "RESTRICT". In the case of MySQL Cluster “NO ACTION” means “deferred check”, i.e. the constraint is checked before commit, allowing user-defined triggers to automatically make changes in order to satisfy the Foreign Key constraints. Configuration There is nothing special you have to do here – Foreign Key constraint checking is enabled by default. If you intend to migrate existing tables from another database or storage engine, for example from InnoDB, there are a couple of best practices to observe: 1. Analyze the structure of the Foreign Key graph and run the ALTER TABLE ENGINE=NDB in the correct sequence to ensure constraints are enforced 2. Alternatively drop the Foreign Key constraints prior to the import process and then recreate when complete. Getting Started Read this blog for a demonstration of using Foreign Keys with MySQL Cluster.  You can download MySQL Cluster 7.3 Labs Release with Foreign Keys today - (select the mysql-cluster-7.3-labs-June-2012 build) If you are new to MySQL Cluster, the Getting Started guide will walk you through installing an evaluation cluster on a singe host (these guides reflect MySQL Cluster 7.2, but apply equally well to 7.3) Post any questions to the MySQL Cluster forum where our Engineering team will attempt to assist you. Post any bugs you find to the MySQL bug tracking system (select MySQL Cluster from the Category drop-down menu) And if you have any feedback, please post them to the Comments section of this blog. Summary MySQL Cluster 7.2 is the GA, production-ready release of MySQL Cluster. This first Labs Release of MySQL Cluster 7.3 gives you the opportunity to preview and evaluate future developments in the MySQL Cluster database, and we are very excited to be able to share that with you. Let us know how you get along with MySQL Cluster 7.3, and other features that you want to see in future releases. * Safe Harbor Statement This information is intended to outline our general product direction.

  • How can I reliably check client identity whilst making DCOM calls to a C# .Net 3.5 Server?

    - by pionium
    Hi, I have an old Win32 C++ DCOM Server that I am rewriting to use C# .Net 3.5. The client applications sit on remote XP machines and are also written in C++. These clients must remain unchanged, hence I must implement the interfaces on new .Net objects. This has been done, and is working successfully regarding the implementation of the interfaces, and all of the calls are correctly being made from the old clients to the new .Net objects. However, I'm having problems obtaining the identity of the calling user from the DCOM Client. In order to try to identify the user who instigated the DCOM call, I have the following code on the server... [DllImport("ole32.dll")] static extern int CoImpersonateClient(); [DllImport("ole32.dll")] static extern int CoRevertToSelf(); private string CallingUser { get { string sCallingUser = null; if (CoImpersonateClient() == 0) { WindowsPrincipal wp = System.Threading.Thread.CurrentPrincipal as WindowsPrincipal; if (wp != null) { WindowsIdentity wi = wp.Identity as WindowsIdentity; if (wi != null && !string.IsNullOrEmpty(wi.Name)) sCallingUser = wi.Name; } if (CoRevertToSelf() != 0) ReportWin32Error("CoRevertToSelf"); } else ReportWin32Error("CoImpersonateClient"); return sCallingUser; } } private static void ReportWin32Error(string sFailingCall) { Win32Exception ex = new Win32Exception(); Logger.Write("Call to " + sFailingCall + " FAILED: " + ex.Message); } When I get the CallingUser property, the value returned the first few times is correct and the correct user name is identified, however, after 3 or 4 different users have successfully made calls (and it varies, so I can't be more specific), further users seem to be identified as users who had made earlier calls. What I have noticed is that the first few users have their DCOM calls handled on their own thread (ie all calls from a particular client are handled by a single unique thread), and then subsequent users are being handled by the same threads as the earlier users, and after the call to CoImpersonateClient(), the CurrentPrincipal matches that of the initial user of that thread. To Illustrate: User Tom makes DCOM calls which are handled by thread 1 (CurrentPrincipal correctly identifies Tom) User Dick makes DCOM calls which are handled by thread 2 (CurrentPrincipal correctly identifies Dick) User Harry makes DCOM calls which are handled by thread 3 (CurrentPrincipal correctly identifies Harry) User Bob makes DCOM calls which are handled by thread 3 (CurrentPrincipal incorrectly identifies him as Harry) As you can see in this illustration, calls from clients Harry and Bob are being handled on thread 3, and the server is identifying the calling client as Harry. Is there something that I am doing wrong? Are there any caveats or restrictions on using Impersonations in this way? Is there a better or different way that I can RELIABLY achieve what I am trying to do? All help would be greatly appreciated. Regards Andrew
