  • Keep Oracle VM 3 Up to Date

    - by Honglin Su
    More and more customers turn to Oracle VM 3 to virtualize their enterprise applications. Oracle VM support subscription is an integrated part of their successes. Customers enjoy the benefit of the industry-leading global support 24x7 for their server virtualization implementation, and receive access to patches, fixes, and updates via Unbreakable Linux Network (ULN). For customers running Oracle systems, Oracle VM support is included in Oracle Premium Support for Systems at no extra cost, and customers receive comprehensive systems coverage that includes single point accountability for Oracle server and storage hardware; integrated software (for example, firmware); and operating system software (Oracle Solaris, Oracle Linux, and Oracle VM). To run a successful virtualization infrastructure, it's important to keep Oracle VM 3 environment up to date by leveraging Oracle VM support resources.  Oracle VM Server Updates: You can easily upgrade Oracle VM Server using a Yum repository. You can download the latest server patch updates from ULN. To receive notification on the software update delivered to Oracle ULN for Oracle VM, you can sign up here. For information on setting up an Oracle VM Server Yum repository and using Oracle VM Manager to perform the upgrade of Oracle VM Servers, see Updating and Upgrading Oracle VM Servers in the Oracle VM User's Guide .  Oracle VM Manager Updates: Get the download instructions at OTN, and apply latest Oracle VM Manager patch. Be sure to review the patch README before you apply the patches. Support customers have access to extremely valuable knowledge notes from My Oracle Support. They are the first to receive useful tips to help address issues in Oracle VM deployments. For example, Upgrade to Oracle VM 3.1.1 using Yum Repository may cause network configuration scripts to be renamed causing network failure after reboot (Doc ID 1464126.1) Oracle VM server reboots after network becomes unresponsive due to deep C-State power management setting (Doc ID 1440197.1) For more information about Oracle's virtualization, visit oracle.com/virtualization.

  • Formal Languages, Inductive Proofs &amp; Regular Expressions

    - by MarkPearl
    So I am slogging away at my UNISA stuff. I have just finished doing the initial once non stop read through the first 11 chapters of my COS 201 Textbook - “Introduction to Computer Theory 2nd Edition” by Daniel Cohen. It has been an interesting couple of days, with familiar concepts coming up as well as some new territory. In this posting I am going to cover the first couple of chapters of the book. Let start with Formal Languages… What exactly is a formal language? Pretty much a no duh question for me but still a good one to ask – a formal language is a language that is defined in a precise mathematical way. Does that mean that the English language is a formal language? I would say no – and my main motivation for this is that one can have an English sentence that is correct grammatically that is also ambiguous. For example the ambiguous sentence: "I once shot an elephant in my pyjamas.” For this and possibly many other reasons that I am unaware of, English is termed a “Natural Language”. So why the importance of formal languages in computer science? Again a no duh question in my mind… If we want computers to be effective and useful tools then we need them to be able to evaluate a series of commands in some form of language that when interpreted by the device no confusion will exist as to what we were requesting. Imagine the mayhem that would exist if a computer misinterpreted a command to print a document and instead decided to delete it. So what is a Formal Language made up of… For my study purposes a language is made up of a finite alphabet. For a formal language to exist there needs to be a specification on the language that will describe whether a string of characters has membership in the language or not. There are two basic ways to do this: By a “machine” that will recognize strings of the language (e.g. Finite Automata). By a rule that describes how strings of a language can be formed (e.g. Regular Expressions). When we use the phrase “string of characters”, we can also be referring to a “word”. What is an Inductive Proof? So I am not to far into my textbook and of course it starts referring to proofs and different types. I have had to go through several different approaches of proofs in the past, but I can never remember their formal names , so when I saw “inductive proof” I thought to myself – what the heck is that? Google to the rescue… An inductive proof is like a normal proof but it employs a neat trick which allows you to prove a statement about an arbitrary number n by first proving it is true when n is 1 and then assuming it is true for n=k and showing it is true for n=k+1. The idea is that if you want to show that someone can climb to the nth floor of a fire escape, you need only show that you can climb the ladder up to the fire escape (n=1) and then show that you know how to climb the stairs from any level of the fire escape (n=k) to the next level (n=k+1). Does this sound like a form of recursion? No surprise then that in the same chapter they deal with recursive definitions. An example of a recursive definition for the language EVEN would the 3 rules below: 2 is in EVEN If x is in EVEN then so is x+2 The only elements in the set EVEN are those that be produced by the rules above. Nothing to exciting… So if a definition for a language is done recursively, then it makes sense that the language can be proved using induction. Regular Expressions So I am wondering to myself what use is this all – in fact – I find this the biggest challenge to any university material is that it is quite hard to find the immediate practical applications of some theory in real life stuff. How great was my joy when I suddenly saw the word regular expression being introduced. I had been introduced to regular expressions on Stack Overflow where I was trying to recognize if some text measurement put in by a user was in a valid form or not. For instance, the imperial system of measurement where you have feet and inches can be represented in so many different ways. I had eventually turned to regular expressions as an easy way to check if my parser could correctly parse the text or not and convert it to a normalize measurement. So some rules about languages and regular expressions… Any finite language can be represented by at least one if not more regular expressions A regular expressions is almost a rule syntax for expressing how regular languages can be formed regular expressions are cool For a regular expression to be valid for a language it must be able to generate all the words in the language and no other words. This is important. It doesn’t help me if my regular expression parses 100% of my measurement texts but also lets one or two invalid texts to pass as well. Okay, so this posting jumps around a bit – but introduces some very basic fundamentals for the subject which will be built on in later postings… Time to go and do some practical examples now…

  • Great Surprise &ndash; MSDN Ultimate

    - by MarkPearl
    So, I attended the Microsoft Community Evening. The attendance was better than I was expecting for December and we had our first Programming Languages Meeting where Gary did a great presentation on an intro to Ruby. The best surprize of the evening happened when I was about to leave, Robert MacLean asked me how we did our MS licensing – the fact being that we were about to reach the end of our empower license with Microsoft and that I had no idea how we were going to afford upgrading it early next year. Well, out comes a Microsoft Visual Studio Ultimate with MSDN 12 month subscription. An absolute awesome gift – thanks Robert! Best gift ever!

  • You should NOT be writing jQuery in SharePoint if&hellip;

    - by Mark Rackley
    Yes… another one of these posts. What can I say? I’m a pot stirrer.. a rabble rouser *rabble rabble* jQuery in SharePoint seems to be a fairly polarizing issue with one side thinking it is the most awesome thing since Princess Leia as the slave girl in Return of the Jedi and the other half thinking it is the worst idea since Mannequin 2: On the Move. The correct answer is OF COURSE “it depends”. But what are those deciding factors that make jQuery an awesome fit or leave a bad taste in your mouth? Let’s see if I can drive the discussion here with some polarizing comments of my own… I know some of you are getting ready to leave your comments even now before reading the rest of the blog, which is great! Iron sharpens iron… These discussions hopefully open us up to understanding the entire process better and think about things in a different way. You should not be writing jQuery in SharePoint if you are not a developer… Let’s start off with my most polarizing and rant filled portion of the blog post. If you don’t know what you are doing or you don’t have a background that helps you understand the implications of what you are writing then you should not be writing jQuery in SharePoint! I truly believe that one of the biggest reasons for the jQuery haters is because of all the bad jQuery out there. If you don’t know what you are doing you can do some NASTY things! One of the best stories I’ve heard about this is from my good friend John Ferringer (@ferringer). John tells this story during our Mythbusters session we do together. One of his clients was undergoing a Denial of Service attack and they couldn’t figure out what was going on! After much searching they found that some genius jQuery developer wrote some code for an image rotator, but did not take into account what happens when there are no images to load! The code just kept hitting the servers over and over and over again which prevented anything else from getting done! Now, I’m NOT saying that I have not done the same sort of thing in the past or am immune from such mistakes. My point is that if you don’t know what you are doing, there are very REAL consequences that can have a major impact on your organization AND they will be hard to track down.  Think how happy your boss will be after you copy and pasted some jQuery from a blog without understanding what it does, it brings down the farm, AND it takes them 3 days to track it back to you.  :/ Good times will not be had. Like it or not JavaScript/jQuery is a programming language. While you .NET people sit on your high horses because your code is compiled and “runs faster” (also debatable), the rest of us will be actually getting work done and delivering solutions while you are trying to figure out why your widget won’t deploy. I can pick at that scab because I write .NET code too and speak from experience. I can do both, and do both well. So, I am not speaking from ignorance here. In JavaScript/jQuery you have variables, loops, conditionals, functions, arrays, events, and built in methods. If you are not a developer you just aren’t going to take advantage of all of that and use it correctly. Ahhh.. but there is hope! There is a lot of jQuery resources out there to help you learn and learn well! There are many experts on the subject that will gladly tell you when you are smoking crack. I just this minute saw a tweet from @cquick with a link to: “jQuery Fundamentals”. I just glanced through it and this may be a great primer for you aspiring jQuery devs. Take advantage of all the resources and become a developer! Hey, it will look awesome on your resume right? You should not be writing jQuery in SharePoint if it depends too much on client resources for a good user experience I’ve said it once and I’ll say it over and over until you understand. jQuery is executed on the client’s computer. Got it? If you are looping through hundreds of rows of data, searching through an enormous DOM, or performing many calculations it is going to take some time! AND if your user happens to be sitting on some old PC somewhere that they picked up at a garage sale their experience will be that much worse! If you can’t give the user a good experience they will not use the site. So, if jQuery is causing the user to have a bad experience, don’t use it. I sometimes go as far to say that you should NOT go to jQuery as a first option for external facing web sites because you have ZERO control over what the end user’s computer will be. You just can’t guarantee an awesome user experience all of the time. Ahhh… but you have no choice? (where have I heard that before?). Well… if you really have no choice, here are some tips to help improve the experience: Avoid screen scraping This is not 1999 and SharePoint is not an old green screen from a mainframe… so why are you treating it like it is? Screen scraping is time consuming and client intensive. Take advantage of tools like SPServices to do your data retrieval when possible. Fine tune your DOM searches A lot of time can be eaten up just searching the DOM and ignoring table rows that you don’t need. Write better jQuery to only loop through tables rows that you need, or only access specific elements you need. Take advantage of Element ID’s to return the one element you are looking for instead of looping through all the DOM over and over again. Write better jQuery Remember this is development. Think about how you can write cleaner, faster jQuery. This directly relates to the previous point of improving your DOM searches, but also when using arrays, variables and loops. Do you REALLY need to loop through that array 3 times? How can you knock it down to 2 times or even 1? When you have lots of calculations and data that you are manipulating every operation adds up. Think about how you can streamline it. Back in the old days before RAM was abundant, Cores were plentiful and dinosaurs roamed the earth, us developers had to take performance into account in everything we did. It’s a lost art that really needs to be used here. You should not be writing jQuery in SharePoint if you are sending a lot of data over the wire… Developer:  “Awesome… you can easily call SharePoint’s web services to retrieve and write data using SPServices!” Administrator: “Crap! you can easily call SharePoint’s web services to retrieve and write data using SPServices!” SPServices may indeed be the best thing that happened to SharePoint since the invention of SharePoint Saturdays by Godfather Lotter… BUT you HAVE to use it wisely! (I REFUSE to make the Spiderman reference). If you do not know what you are doing your code will bring back EVERY field and EVERY row from a list and push that over the internet with all that lovely XML wrapped around it. That can be a HUGE amount of data and will GREATLY impact performance! Calling several web service methods at the same time can cause the same problem and can negatively impact your SharePoint servers. These problems, thankfully, are not difficult to rectify if you are careful: Limit list data retrieved Use CAML to reduce the number of rows returned and limit the fields returned using ViewFields.  You should definitely be doing this regardless. If you aren’t I hope your admin thumps you upside the head. Batch large list updates You may or may not have noticed that if you try to do large updates (hundreds of rows) that the performance is either completely abysmal or it fails over half the time. You can greatly improve performance and avoid timeouts by breaking up your updates into several smaller updates. I don’t know if there is a magic number for best performance, it really depends on how much data you are sending back more than the number of rows. However, I have found that 200 rows generally works well.  Play around and find the right number for your situation. Delay Web Service calls when possible One of the cool things about jQuery and SPServices is that you can delay queries to the server until they are actually needed instead of doing them all at once. This can lead to performance improvements over DataViewWebParts and even .NET code in the right situations. So, don’t load the data until it’s needed. In some instances you may not need to retrieve the data at all, so why retrieve it ALL the time? You should not be writing jQuery in SharePoint if there is a better solution… jQuery is NOT the silver bullet in SharePoint, it is not the answer to every question, it is just another tool in the developers toolkit. I urge all developers to know what options exist out there and choose the right one! Sometimes it will be jQuery, sometimes it will be .NET,  sometimes it will be XSL, and sometimes it will be some other choice… So, when is there a better solution to jQuery? When you can’t get away from performance problems Sometimes jQuery will just give you horrible performance regardless of what you do because of unavoidable obstacles. In these situations you are going to have to figure out an alternative. Can I do it with a DVWP or do I have to crack open Visual Studio? When you need to do something that jQuery can’t do There are lots of things you can’t do in jQuery like elevate privileges, event handlers, workflows, or interact with back end systems that have no web service interface. It just can’t do everything. When it can be done faster and more efficiently another way Why are you spending time to write jQuery to do a DataViewWebPart that would take 5 minutes? Or why are you trying to implement complicated logic that would be simple to do in .NET? If your answer is that you don’t have the option, okay. BUT if you do have the option don’t reinvent the wheel! Take advantage of the other tools. The answer is not always jQuery… sorry… the kool-aid tastes good, but sweet tea is pretty awesome too. You should not be using jQuery in SharePoint if you are a moron… Let’s finish up the blog on a high note… Yes.. it’s true, I sometimes type things just to get a reaction… guess this section title might be a good example, but it feels good sometimes just to type the words that a lot of us think… So.. don’t be that guy! Another good buddy of mine that works for Microsoft told me. “I loved jQuery in SharePoint…. until I had to support it.”. He went on to explain that some user was making several web service calls on a page using jQuery and then was calling Microsoft and COMPLAINING because the page took so long to load… DUH! What do you expect to happen when you are pushing that much data over the wire and are making that many web service calls at once!! It’s one thing to write that kind of code and accept it’s just going to take a while, it’s COMPLETELY another issue to do that and then complain when it’s not lightning fast!  Someone’s gene pool needs some chlorine. So, I think this is a nice summary of the blog… DON’T be that guy… don’t be a moron. How can you stop yourself from being a moron? Ah.. glad you asked, here are some tips: Think Is jQuery the right solution to my problem? Is there a better approach? What are the implications and pitfalls of using jQuery in this situation? Search What are others doing? Does someone have a better solution? Is there a third party library that does the same thing I need? Plan Write good jQuery. Limit calculations and data sent over the wire and don’t reinvent the wheel when possible. Test Okay, it works well on your machine. Try it on others ESPECIALLY if this is for an external site. Test with empty data. Test with hundreds of rows of data. Test as many scenarios as possible. Monitor those server resources to see the impact there as well. Ask the experts As smart as you are, there are people smarter than you. Even the experts talk to each other to make sure they aren't doing something stupid.

  • Oracle collaborates with leading IT vendors on Cloud Management Standards

    - by Anand Akela
    During the last couple of days, two key specifications for cloud management standards have been announced. Oracle collaborated with leading technology vendors from the IT industry on both of these cloud management specifications. One of the specifications focuses "Infrastructure as a Service" ( IaaS )  cloud service model , while the other specification announced today focuses on "Platform as a Service" ( PaaS ) cloud service model. Please see The NIST Definition of Cloud Computing to learn more about IaaS and PaaS . Earlier today Oracle , CloudBees, Cloudsoft, Huawei, Rackspace, Red Hat, and Software AG   announced the Cloud Application Management for Platforms (CAMP) specification that will be submitted to Organization for the Advancement of Structured Information Standards (OASIS) for development of an industry standard, in an effort to help ensure interoperability for deploying and managing applications across cloud environments.  Typical PaaS architecture - Source : CAMP specification The CAMP specification defines the artifacts and APIs that need to be offered by a PaaS cloud to manage the building, running, administration, monitoring and patching of applications in the cloud. Its purpose is to enable interoperability among self-service interfaces to PaaS clouds by defining artifacts and formats that can be used with any conforming cloud and enable independent vendors to create tools and services that interact with any conforming cloud using the defined interfaces. Cloud vendors can use these interfaces to develop new PaaS offerings that will interact with independently developed tools and components. In a separate cloud standards announcement yesterday, the Distributed Management Task Force ( DMTF ), the organization bringing the IT industry together to collaborate on systems management standards development, validation, promotion and adoption, released the new Cloud Infrastructure Management Interface (CIMI) specification. Oracle collaborated with various technology vendors and industry organizations on this specification. CIMI standardizes interactions between cloud environments to achieve interoperable cloud infrastructure management between service providers and their consumers and developers, enabling users to manage their cloud infrastructure use easily and without complexity. DMTF developed CIMI as a self-service interface for infrastructure clouds ( IaaS focus ) , allowing users to dynamically provision, configure and administer their cloud usage with a high-level interface that greatly simplifies cloud systems management. Mark Carlson, Principal Cloud Strategist at Oracle provides more details about CAMP  and CIMI his blog . Stay Connected: Twitter |  Face book |  You Tube |  Linked in |  Newsletter

  • Windows CE: SDK Doesn’t Show up in Visual Studio 2008

    - by Bruce Eitman
    A customer recently contacted me because after installing an SDK it didn’t show up in Visual Studio 2008.  So being a good vendor I installed VS2008 and then installed the SDK – no problem the SDK showed up and I could create projects based on it. I let the customer know that the SDK definitely works with VS2008. The customer got back to me and asked what OS I was using. Hmm, how could that play into this? I told him that I use Windows XP, and it turned out that he is way more modern than I am and is using both Windows Vista and 7. The customer opened a support case with Microsoft. The answer turns out to be that the SDK install requires the user to be logged on as an administrator when installing on Windows Vista and 7 for the SDK to show up in Visual Studio 2008. This problem does not seem to exist for Visual Studio 2005 on those operating systems. The actual instructions from Microsoft Support are: 1)      Make sure Visual Studio 2008 is not running. I also shut down the device emulator manager but you may not be using that. 2)      Open a “Visual Studio 2008 Command Prompt” as Administrator. On Windows 7 just right click the short cut and pick the “Run as administrator” option. 3)      Enter the following command: msiexec /log SDKInstallLog.txt /package <the path to your .msi file> 4)      When asked if you wish to do a custom or complete install pick custom 5)      Instruct the installer to omit the installation of the documentation. This was something I found about CE 6 SDK installation issue and may have no bearing upon your problem but I did it anyway. 6)      Install   Copyright © 2010 – Bruce Eitman All Rights Reserved

  • Book Reviews: Art of Community and Eyetracking Web Usability

    - by ultan o'broin
    Holidays time offers a chance to catch up on some user experience and user assistance related material. So, two short book reviews (which I considered using my new Tumblr blog for. More about that another time) coming up. The Art of Community by Jono Bacon Excellent starting point for anyone wanting to get going in the community software (FLOSS, for example) space or understand how to set up, manage, and leverage the collective intelligence of communities for whatever ends. The book is a little too long in my opinion, and of course, usage of what Jono is recommending needs to be nuanced and adapted for enterprise applications space (hardly surprising there is a lot about Ubuntu, Lug Radio, and so on given Jono's interests). Shame there wasn't more information on international, non-English community considerations too. Still, some great ideas and insight into setting up and managing communities that I will leverage (watch out for the results on this blog, later in 2011). One section, on collaborative writing really jumped out. It reinforced the whole idea that to successful community initiatives are based on instigators knowing what makes the community tick in the first place. How about this for insight into user profiles for people who write community user assistance (OK then, "doc") and what tools they might use (in this case, we're talking about Jokosher): "Most people who write documentation for open source software projects would fall into the category of power user. They are technology enthusiasts who are not interested in the super-technical avenues of programming, but want to help out. Many of these people have good writing skills and a good knowledge of using the software, so the documentation fit is natural. With Jokosher we wanted to acknowledge this profile of user. As such, instead of focussing on complex text processing tools, we encouraged our documentation contributors to use a wiki." The book is available for free here, and well as being available from usual sources. Eyetracking Web Usability by Jakob Nielsen and Kara Prentice Another fine book by established experts. I have some field experience of eyetracking studies myself --in the user assistance for enterprise applications space--though Jakob and Kara concentrate on websites for their research here. I would caution how much about websites transfers easily to the applications space, especially enterprise applications, as claimed in the book too. However, Jakob and Kara do make the case very well that understanding design goals (for example, productivity improvement in the case of applications) and the context of the software use is critical. Executing a study using eyetracking technology requires that you know what you want to test, can set up realistic tasks for testing by representative testers, and then analyze the results. Be precise, as lots of data will be generated (I think the authors underplay the effort in analyzing data too). What I found disappointing was the lack of emphasis on eyetracking as only part of the usability solution. It's really for fine-tuning designs in my opinion, and should be used after other design reviews. I also wasn't that crazy about the level of disengagement between the qualitative and quantitative side of this kind of testing that the book indicated. I think it is useful to have testers verbalize their thoughts and for test engineers to prompt, intervene, or guide as necessary. More on cultural or international aspects to usability testing might have been included too (websites are available to everyone). To conclude, I enjoyed the book, took on board some key takeaways about methodologies and found the recommendations sensible and easy to follow (for example about Forms layouts). Applying enterprise applications requirements such as those relating to user profiles, design goals, and overall context of use in conjunction with what's in this book would be the way to go here. It also made me think of how interesting it would be to compare eyetracking findings between website and enterprise applications usage.

  • Google TV Gets Bad Reception. Can Media Center Pull in the Signal?

    - by andrewbrust
    The news hit Monday morning that Google has decided to delay the release of its Google TV platform, and has asked its OEMs to delay any products that embed the software.  Coming just about two weeks prior to the 2011 Consumer Electronics Show (CES), Google’s timing is about the worst imaginable.  CES is where the platform should have had its coming out party, especially given all the anticipation that has built up since its initial announcement came 7 months ago. At last year’s CES, it seemed every consumer electronics company had fashioned its own software stack for Internet-based video programming and applications/widgets on its TVs, optical disc players and set top boxes.  In one case, I even saw two platforms on a single TV set (one provided by Yahoo and the other one native to the TV set). The whole point of Google TV was to solve this problem and offer a standard, embeddable platform.  But that won’t be happening, at least not for a while.  Google seems unable to get it together, and more proprietary approaches, like Apple TV, don’t seem to be setting the world of TV-Internet convergence on fire, either. It seems to me, that when it comes to building a “TV operating system,” Windows Media Center is still the best of a bad bunch.  But it won’t stay so for much longer without some changes.  Will Redmond pick up the ball that Google has fumbled?  I’m skeptical, but hopeful.  Regardless, here are some steps that could help Microsoft make the most of Google’s faux pas: Introduce a new Media Center version that uses XBox 360, rather than Windows 7 (or 8), as the platform.  TV platforms should be appliance-like, not PC-like.  Combine that notion with the runaway sales numbers for Xbox 360 Kinect, and the mass appeal it has delivered for Xbox, and the switch form Windows makes even more sense. As I have pointed out before, Microsoft’s Xbox implementation of its Mediaroom platform (announced and demoed at last year’s CES) gets Redmond 80% of the way toward this goal.  Nothing stops Microsoft from going the other 20%, other than its own apathy, which I hope has dissipated. Reverse the decision to remove Drive Extender technology from Windows Home Server (WHS), and create deep integration between WHS and Media Center.  I have suggested this previously as well, but the recent announcement that Drive Extender would be dropped from WHS 2.0 creates the need for me to a) join the chorus of people urging Microsoft to reconsider and b) reiterate the importance of Media Center-WHS integration in the context of a Google compete scenario. Enable Windows Phone 7 (WP7) as a Media Center client.  This would tighten the integration loop already established between WP7, Xbox and Zune.  But it would also counter Echostar/DISH Network/Sling Media, strike a blow against Google/Android (and even Apple/iOS) and could be the final strike against TiVO. Bring the WP7 user interface to Media Center and Kinect-enable it.  This would further the integration discussed above and would be appropriate recognition of WP7’s Metro UI having been built on the heritage of the original Media Center itself.  And being able to run your DVR even if you can’t find the remote (or can’t see its buttons in the dark) could be a nifty gimmick. Microsoft can do this but its consumer-oriented organization, responsible for Xbox, Zune and WP7, has to take the reins here, or none of this will likely work.  There’s a significant chance that won’t happen, but I won’t let that stop me from hoping that it does and insisting that it must.  Honestly, this fight is Microsoft’s to lose.

  • Searching for the last logon of users in Active Directory

    - by Robert May
    I needed to clean out a bunch of old accounts at Veracity Solutions, and wanted to delete those that hadn’t used their account in more than a year. I found that AD has a property on objects called the lastLogonTimestamp.  However, this value isn’t exposed to you in any useful fashion.  Sure, you can pull up ADSI Edit and and eventually get to it there, but it’s painful. I spent some time searching, and discovered that there’s not much out there to help, so I thought a blog post showing exactly how to get at this information would be in order. Basically, what you end up doing is using System.DirectoryServices to search for accounts and then filtering those for users, doing some conversion and such to make it happen.  Basically, the end result of this is that you get a list of users with their logon information and you can then do with that what you will.  I turned my list into an observable collection and bound it into a XAML form. One important note, you need to add a reference to ActiveDs Type Library in the COM section of the world in references to get to LargeInteger. Here’s the class: namespace Veracity.Utilities { using System; using System.Collections.Generic; using System.DirectoryServices; using ActiveDs; using log4net; /// <summary> /// Finds users inside of the active directory system. /// </summary> public class UserFinder { /// <summary> /// Creates the default logger /// </summary> private static readonly ILog log = LogManager.GetLogger(typeof(UserFinder)); /// <summary> /// Finds last logon information /// </summary> /// <param name="domain">The domain to search.</param> /// <param name="userName">The username for the query.</param> /// <param name="password">The password for the query.</param> /// <returns>A list of users with their last logon information.</returns> public IList<UserLoginInformation> GetLastLogonInformation(string domain, string userName, string password) { IList<UserLoginInformation> result = new List<UserLoginInformation>(); DirectoryEntry entry = new DirectoryEntry(domain, userName, password, AuthenticationTypes.Secure); DirectorySearcher directorySearcher = new DirectorySearcher(entry); directorySearcher.PropertyNamesOnly = true; directorySearcher.PropertiesToLoad.Add("name"); directorySearcher.PropertiesToLoad.Add("lastLogonTimeStamp"); SearchResultCollection searchResults; try { searchResults = directorySearcher.FindAll(); } catch (System.Exception ex) { log.Error("Failed to do a find all.", ex); throw; } try { foreach (SearchResult searchResult in searchResults) { DirectoryEntry resultEntry = searchResult.GetDirectoryEntry(); if (resultEntry.SchemaClassName == "user") { UserLoginInformation logon = new UserLoginInformation(); logon.Name = resultEntry.Name; PropertyValueCollection timeStampObject = resultEntry.Properties["lastLogonTimeStamp"]; if (timeStampObject.Count > 0) { IADsLargeInteger logonTimeStamp = (IADsLargeInteger)timeStampObject[0]; long lastLogon = (long)((uint)logonTimeStamp.LowPart + (((long)logonTimeStamp.HighPart) << 32)); logon.LastLogonTime = DateTime.FromFileTime(lastLogon); } result.Add(logon); } } } catch (System.Exception ex) { log.Error("Failed to iterate search results.", ex); throw; } return result; } } } Some important things to note: Username and Password can be set to null and if your computer us part of the domain, this may still work. Domain should be set to something like LDAP://servername/CN=Users,CN=Domain,CN=com You’re actually getting a com object back, so that’s why the LongInteger conversions are happening.  The class for UserLoginInformation looks like this:   namespace Veracity.Utilities { using System; /// <summary> /// Represents user login information. /// </summary> public class UserLoginInformation { /// <summary> /// Gets or sets Name /// </summary> public string Name { get; set; } /// <summary> /// Gets or sets LastLogonTime /// </summary> public DateTime LastLogonTime { get; set; } /// <summary> /// Gets the age of the account. /// </summary> public TimeSpan AccountAge { get { TimeSpan result = TimeSpan.Zero; if (this.LastLogonTime != DateTime.MinValue) { result = DateTime.Now.Subtract(this.LastLogonTime); } return result; } } } } I hope this is useful and instructive.

  • Oracle B2B 11g - Transport Layer Acknowledgement

    - by Nitesh Jain Oracle
    In Health Care Industry,Acknowledgement or Response should be sent back very fast. Once any message received, Acknowledgement should be sent back to TP. Oracle B2B provides a solution to send acknowledgement or Response from transport layer of mllp that is called as immediate acknowledgment. Immediate acknowledgment is generated and transmitted in the transport layer. It is an alternative to the functional acknowledgment, which generates after processing/validating the data in document layer. Oracle B2B provides four types of immediate acknowledgment: Default: Oracle B2B parses the incoming HL7 message and generates an acknowledgment from it. This mode uses the details from incoming payload and generate the acknowledgement based on incoming HL7 message control number, sender and application identification. By default, an Immediate ACK is a generic ACK. Trigger event can also sent back by using Map Trigger Event property. If mapping the MSH.10 of the ACK with the MSH.10 of the incoming business message is required, then enable the Map ACK Control ID property. Simple: B2B sends the predefined acknowledgment message to the sender without parsing the incoming message. Custom: Custom immediate Ack/Response mode gives a user to define their own response/acknowledgement. This is configurable using file in the Custom Immediate ACK File property. Negative: In this case, immediate ACK will be returned only in the case of exceptions.

  • Performing a silent install of JDeveloper

    - by draikes
    Installing JDeveloper Now that you have downloaded the latest version of JDeveloper from: the Oracle technology network, you are almost ready to install it. The problem is that the GUI installer is not as accessible as it could be. However, there is an alternative called a silent install. To perform a silent install, follow these steps: Download the silent.xml file into the same folder as the JDeveloper installer. You can customize the silent.xml file by setting the folder where JDeveloper will be installed, and by setting the location where you have a 1.6 jdk installed with the accessbridge already configured. The defaults are: JDeveloper wil lbe installed at c:\jdev a jdk is installed at c:\jdk\1.6.0_25 (see instructions in the top of the silent.xml file). Open a command window and navigate to the folder where the JDeveloper installer and silent.xml files are located. Run the following command: jdevstudio11120install.exe -mode=silent -silent_xml=silent.xml -log=install.log Note: this assumes that you are installing JDeveloper 11.1.2.0.0. Change the above command to match the installer package you have. This command will start by extracting the archive then the oracle installer will launch, but you just have to wait until the command prompt returns and voila it will be installed. To run JDeveloper: Now you can use windows explorer to navigate to the %JDEV_HOME% as specified in the silent.xml file (c:\jdev unless you changed it)and drill down to: jdeveloper\jdev\bin and now you have a couple of choices. If you have a 32-bit jdk configured with the accessbridge, then run jdevw.exe, however, if you have a 64-bit jdk copnfigured with the accessbridge, you should run jdev64w.exe. For instructiosn on setting up Accessbridge 2.0.1, see my earlier post. Disclaimer: As always if something doesn't quite go as planned, and you have a problem, please feel free to contact me via email at: don dot raikes at oracle dot com.

  • Using Oracle Proxy Authentication with JPA (eclipselink-Style)

    - by olaf.heimburger
    Security is a very intriguing topic. You will find it everywhere and you need to implement it everywhere. Yes, you need. Unfortunately, one can easily forget it while implementing the last mile. The Last Mile In a multi-tier application it is a common practice to use connection pools between the business layer and the database layer. Connection pools are quite useful to speed database connection creation and to split the load. Another very common practice is to use a specific, often called technical, user to connect to the database. This user has authentication and authorization rules that apply to all application users. Imagine you've put every effort to define roles for different types of users that use your application. These roles are necessary to differentiate between normal users, premium users, and administrators (I bet you will find or already have more roles in your application). While these user roles are pretty well used within your application, once the flow of execution enters the database everything is gone. Each and every user just has one role and is the same database user. Issues? What Issues? As long as things go well, this is not a real issue. However, things do not go well all the time. Once your application becomes famous performance decreases in certain situations or, more importantly, current and upcoming regulations and laws require that your application must be able to apply different security measures on a per user role basis at every stage of your application. If you only have a bunch of users with the same name and role you are not able to find the application usage profile that causes the performance issue, or which user has accessed data that he/she is not allowed to. Another thread to your role concept is that databases tend to be used by different applications and tools. These tools can be developer tools like SQL*Plus, SQL Developer, etc. or end user applications like BI Publisher, Oracle Forms and so on. These tools have no idea of your applications role concept and access the database the way they think is appropriate. A big oversight for your perfect role model and a big nightmare for your Chief Security Officer. Speaking of the CSO, brings up another issue: Password management. Once your technical user account is compromised, every user is able to do things that he/she is not expected to do from the design of your application. Counter Measures In the Oracle world a common counter measure is to use Virtual Private Database (VPD). This restricts the values a database user can see to the allowed minimum. However, it doesn't help in regard of a connection pool user, because this one is still not the real user. Oracle Proxy Authentication Another feature of the Oracle database is Proxy Authentication. First introduced with version 9i it is a quite useful feature for nearly every situation. The main idea behind Proxy Authentication is, to create a crippled database user who has only connect rights. Even if this user is compromised the risks are well understood and fairly limited. This user can be used in every situation in which you need to connect to the database, no matter which tool or application (see above) you use.The proxy user is perfect for multi-tier connection pools. CREATE USER app_user IDENTIFIED BY abcd1234; GRANT CREATE SESSION TO app_user; But what if you need to access real data? Well, this is the primary use case, isn't it? Now is the time to bring the application's role concept into play. You define database roles that define the grants for your identified user groups. Once you have these groups you grant access through the proxy user with the application role to the specific user. CREATE ROLE app_role_a; GRANT app_role_a TO scott; ALTER USER scott GRANT CONNECT THROUGH app_user WITH ROLE app_role_a; Now, hr has permission to connect to the database through the proxy user. Through the role you can restrict the hr's rights the are needed for the application only. If hr connects to the database directly all assigned role and permissions apply. Testing the Setup To test the setup you can use SQL*Plus and connect to your database: $ sqlplus app_user[hr]/abcd1234 Java Persistence API The Java Persistence API (JPA) is a fairly easy means to build applications that retrieve data from the database and put it into Java objects. You use plain old Java objects (POJOs) and mixin some Java annotations that define how the attributes of the object are used for storing data from the database into the Java object. Here is a sample for objects from the HR sample schema EMPLOYEES table. When using Java annotations you only specify what can not be deduced from the code. If your Java class name is Employee but the table name is EMPLOYEES, you need to specify the table name, otherwise it will fail. package demo.proxy.ejb; import java.io.Serializable; import java.sql.Timestamp; import java.util.List; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.Id; import javax.persistence.JoinColumn; import javax.persistence.ManyToOne; import javax.persistence.NamedQueries; import javax.persistence.NamedQuery; import javax.persistence.OneToMany; import javax.persistence.Table; @Entity @NamedQueries({ @NamedQuery(name = "Employee.findAll", query = "select o from Employee o") }) @Table(name = "EMPLOYEES") public class Employee implements Serializable { @Column(name="COMMISSION_PCT") private Double commissionPct; @Column(name="DEPARTMENT_ID") private Long departmentId; @Column(nullable = false, unique = true, length = 25) private String email; @Id @Column(name="EMPLOYEE_ID", nullable = false) private Long employeeId; @Column(name="FIRST_NAME", length = 20) private String firstName; @Column(name="HIRE_DATE", nullable = false) private Timestamp hireDate; @Column(name="JOB_ID", nullable = false, length = 10) private String jobId; @Column(name="LAST_NAME", nullable = false, length = 25) private String lastName; @Column(name="PHONE_NUMBER", length = 20) private String phoneNumber; private Double salary; @ManyToOne @JoinColumn(name = "MANAGER_ID") private Employee employee; @OneToMany(mappedBy = "employee") private List employeeList; public Employee() { } public Employee(Double commissionPct, Long departmentId, String email, Long employeeId, String firstName, Timestamp hireDate, String jobId, String lastName, Employee employee, String phoneNumber, Double salary) { this.commissionPct = commissionPct; this.departmentId = departmentId; this.email = email; this.employeeId = employeeId; this.firstName = firstName; this.hireDate = hireDate; this.jobId = jobId; this.lastName = lastName; this.employee = employee; this.phoneNumber = phoneNumber; this.salary = salary; } public Double getCommissionPct() { return commissionPct; } public void setCommissionPct(Double commissionPct) { this.commissionPct = commissionPct; } public Long getDepartmentId() { return departmentId; } public void setDepartmentId(Long departmentId) { this.departmentId = departmentId; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public Long getEmployeeId() { return employeeId; } public void setEmployeeId(Long employeeId) { this.employeeId = employeeId; } public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public Timestamp getHireDate() { return hireDate; } public void setHireDate(Timestamp hireDate) { this.hireDate = hireDate; } public String getJobId() { return jobId; } public void setJobId(String jobId) { this.jobId = jobId; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } public String getPhoneNumber() { return phoneNumber; } public void setPhoneNumber(String phoneNumber) { this.phoneNumber = phoneNumber; } public Double getSalary() { return salary; } public void setSalary(Double salary) { this.salary = salary; } public Employee getEmployee() { return employee; } public void setEmployee(Employee employee) { this.employee = employee; } public List getEmployeeList() { return employeeList; } public void setEmployeeList(List employeeList) { this.employeeList = employeeList; } public Employee addEmployee(Employee employee) { getEmployeeList().add(employee); employee.setEmployee(this); return employee; } public Employee removeEmployee(Employee employee) { getEmployeeList().remove(employee); employee.setEmployee(null); return employee; } } JPA could be used in standalone applications and Java EE containers. In both worlds you normally create a Facade to retrieve or store the values of the Entities to or from the database. The Facade does this via an EntityManager which will be injected by the Java EE container. Here is sample Facade Session Bean for a Java EE container. package demo.proxy.ejb; import java.util.HashMap; import java.util.List; import javax.ejb.Local; import javax.ejb.Remote; import javax.ejb.Stateless; import javax.persistence.EntityManager; import javax.persistence.PersistenceContext; import javax.persistence.Query; import javax.interceptor.AroundInvoke; import javax.interceptor.InvocationContext; import oracle.jdbc.driver.OracleConnection; import org.eclipse.persistence.config.EntityManagerProperties; import org.eclipse.persistence.internal.jpa.EntityManagerImpl; @Stateless(name = "DataFacade", mappedName = "ProxyUser-TestEJB-DataFacade") @Remote @Local public class DataFacadeBean implements DataFacade, DataFacadeLocal { @PersistenceContext(unitName = "TestEJB") private EntityManager em; private String username; public Object queryByRange(String jpqlStmt, int firstResult, int maxResults) { // setSessionUser(); Query query = em.createQuery(jpqlStmt); if (firstResult 0) { query = query.setFirstResult(firstResult); } if (maxResults 0) { query = query.setMaxResults(maxResults); } return query.getResultList(); } public Employee persistEmployee(Employee employee) { // setSessionUser(); em.persist(employee); return employee; } public Employee mergeEmployee(Employee employee) { // setSessionUser(); return em.merge(employee); } public void removeEmployee(Employee employee) { // setSessionUser(); employee = em.find(Employee.class, employee.getEmployeeId()); em.remove(employee); } /** select o from Employee o */ public List getEmployeeFindAll() { Query q = em.createNamedQuery("Employee.findAll"); return q.getResultList(); } Putting Both Together To use Proxy Authentication with JPA and within a Java EE container you have to take care of the additional requirements: Use an OCI JDBC driver Provide the user name that connects through the proxy user Use an OCI JDBC driver To use the OCI JDBC driver you need to set up your JDBC data source file to use the correct JDBC URL. hr jdbc:oracle:oci8:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SID=XE))) oracle.jdbc.OracleDriver user app_user 62C32F70E98297522AD97E15439FAC0E SQL SELECT 1 FROM DUAL jdbc/hrDS Application Additionally you need to make sure that the version of the shared libraries of the OCI driver match the version of the JDBC driver in your Java EE container or Java application and are within your PATH (on Windows) or LD_LIBRARY_PATH (on most Unix-based systems). Installing the Oracle Database Instance Client software works perfectly. Provide the user name that connects through the proxy user This part needs some modification of your application software and session facade. Session Facade Changes In the Session Facade we must ensure that every call that goes through the EntityManager must be prepared correctly and uniquely assigned to this session. The second is really important, as the EntityManager works with a connection pool and can not guarantee that we set the proxy user on the connection that will be used for the database activities. To avoid changing every method call of the Session Facade we provide a method to set the username of the user that connects through the proxy user. This method needs to be called by the Facade client bfore doing anything else. public void setUsername(String name) { username = name; } Next we provide a means to instruct the TopLink EntityManager Delegate to use Oracle Proxy Authentication. (I love small helper methods to hide the nitty-gritty details and avoid repeating myself.) private void setSessionUser() { setSessionUser(username); } private void setSessionUser(String user) { if (user != null && !user.isEmpty()) { EntityManagerImpl emDelegate = ((EntityManagerImpl)em.getDelegate()); emDelegate.setProperty(EntityManagerProperties.ORACLE_PROXY_TYPE, OracleConnection.PROXYTYPE_USER_NAME); emDelegate.setProperty(OracleConnection.PROXY_USER_NAME, user); emDelegate.setProperty(EntityManagerProperties.EXCLUSIVE_CONNECTION_MODE, "Always"); } } The final step is use the EJB 3.0 AroundInvoke interceptor. This interceptor will be called around every method invocation. We therefore check whether the Facade methods will be called or not. If so, we set the user for proxy authentication and the normal method flow continues. @AroundInvoke public Object proxyInterceptor(InvocationContext invocationCtx) throws Exception { if (invocationCtx.getTarget() instanceof DataFacadeBean) { setSessionUser(); } return invocationCtx.proceed(); } Benefits Using Oracle Proxy Authentification has a number of additional benefits appart from implementing the role model of your application: Fine grained access control for temporary users of the account, without compromising the original password. Enabling database auditing and logging. Better identification of performance bottlenecks.
