• Revisiting ANTS Performance Profiler 7.4

  - by James Michael Hare

  Last year, I did a small review on the ANTS Performance Profiler 6.3, now that it’s a year later and a major version number higher, I thought I’d revisit the review and revise my last post. This post will take the same examples as the original post and update them to show what’s new in version 7.4 of the profiler. Background A performance profiler’s main job is to keep track of how much time is typically spent in each unit of code. This helps when we have a program that is not running at the performance we expect, and we want to know where the program is experiencing issues. There are many profilers out there of varying capabilities. Red Gate’s typically seem to be the very easy to “jump in” and get started with very little training required. So let’s dig into the Performance Profiler. I’ve constructed a very crude program with some obvious inefficiencies. It’s a simple program that generates random order numbers (or really could be any unique identifier), adds it to a list, sorts the list, then finds the max and min number in the list. Ignore the fact it’s very contrived and obviously inefficient, we just want to use it as an example to show off the tool: 1: // our test program 2: public static class Program 3: { 4: // the number of iterations to perform 5: private static int _iterations = 1000000; 6: 7: // The main method that controls it all 8: public static void Main() 9: { 10: var list = new List<string>(); 11: 12: for (int i = 0; i < _iterations; i++) 13: { 14: var x = GetNextId(); 15: 16: AddToList(list, x); 17: 18: var highLow = GetHighLow(list); 19: 20: if ((i % 1000) == 0) 21: { 22: Console.WriteLine("{0} - High: {1}, Low: {2}", i, highLow.Item1, highLow.Item2); 23: Console.Out.Flush(); 24: } 25: } 26: } 27: 28: // gets the next order id to process (random for us) 29: public static string GetNextId() 30: { 31: var random = new Random(); 32: var num = random.Next(1000000, 9999999); 33: return num.ToString(); 34: } 35: 36: // add it to our list - very inefficiently! 37: public static void AddToList(List<string> list, string item) 38: { 39: list.Add(item); 40: list.Sort(); 41: } 42: 43: // get high and low of order id range - very inefficiently! 44: public static Tuple<int,int> GetHighLow(List<string> list) 45: { 46: return Tuple.Create(list.Max(s => Convert.ToInt32(s)), list.Min(s => Convert.ToInt32(s))); 47: } 48: } So let’s run it through the profiler and see what happens! Visual Studio Integration First, let’s look at how the ANTS profilers integrate with Visual Studio’s menu system. Once you install the ANTS profilers, you will get an ANTS menu item with several options: Notice that you can either Profile Performance or Launch ANTS Performance Profiler. These sound similar but achieve two slightly different actions: Profile Performance: this immediately launches the profiler with all defaults selected to profile the active project in Visual Studio. Launch ANTS Performance Profiler: this launches the profiler much the same way as starting it from the Start Menu. The profiler will pre-populate the application and path information, but allow you to change the settings before beginning the profile run. So really, the main difference is that Profile Performance immediately begins profiling with the default selections, where Launch ANTS Performance Profiler allows you to change the defaults and attach to an already-running application. Let’s Fire it Up! So when you fire up ANTS either via Start Menu or Launch ANTS Performance Profiler menu in Visual Studio, you are presented with a very simple dialog to get you started: Notice you can choose from many different options for application type. You can profile executables, services, web applications, or just attach to a running process. In fact, in version 7.4 we see two new options added: ASP.NET Web Application (IIS Express) SharePoint web application (IIS) So this gives us an additional way to profile ASP.NET applications and the ability to profile SharePoint applications as well. You can also choose your level of detail in the Profiling Mode drop down. If you choose Line-Level and method-level timings detail, you will get a lot more detail on the method durations, but this will also slow down profiling somewhat. If you really need the profiler to be as unintrusive as possible, you can change it to Sample method-level timings. This is performing very light profiling, where basically the profiler collects timings of a method by examining the call-stack at given intervals. Which method you choose depends a lot on how much detail you need to find the issue and how sensitive your program issues are to timing. So for our example, let’s just go with the line and method timing detail. So, we check that all the options are correct (if you launch from VS2010, the executable and path are filled in already), and fire it up by clicking the [Start Profiling] button. Profiling the Application Once you start profiling the application, you will see a real-time graph of CPU usage that will indicate how much your application is using the CPU(s) on your system. During this time, you can select segments of the graph and bookmark them, giving them mnemonic names. This can be useful if you want to compare performance in one part of the run to another part of the run. Notice that once you select a block, it will give you the call tree breakdown for that selection only, and the relative performance of those calls. Once you feel you have collected enough information, you can click [Stop Profiling] to stop the application run and information collection and begin a more thorough analysis. Analyzing Method Timings So now that we’ve halted the run, we can look around the GUI and see what we can see. By default, the times are shown in terms of percentage of time of the total run of the application, though you can change it in the View menu item to milliseconds, ticks, or seconds as well. This won’t affect the percentages of methods, it only affects what units the times are shown. Notice also that the major hotspot seems to be in a method without source, ANTS Profiler will filter these out by default, but you can right-click on the line and remove the filter to see more detail. This proves especially handy when a bottleneck is due to a method in the BCL. So now that we’ve removed the filter, we see a bit more detail: In addition, ANTS Performance Profiler gives you the ability to decompile the methods without source so that you can dive even deeper, though typically this isn’t necessary for our purposes. When looking at timings, there are generally two types of timings for each method call: Time: This is the time spent ONLY in this method, not including calls this method makes to other methods. Time With Children: This is the total of time spent in both this method AND including calls this method makes to other methods. In other words, the Time tells you how much work is being done exclusively in this method, and the Time With Children tells you how much work is being done inclusively in this method and everything it calls. You can also choose to display the methods in a tree or in a grid. The tree view is the default and it shows the method calls arranged in terms of the tree representing all method calls and the parent method that called them, etc. This is useful for when you find a hot-spot method, you can see who is calling it to determine if the problem is the method itself, or if it is being called too many times. The grid method represents each method only once with its totals and is useful for quickly seeing what method is the trouble spot. In addition, you can choose to display Methods with source which are generally the methods you wrote (as opposed to native or BCL code), or Any Method which shows not only your methods, but also native calls, JIT overhead, synchronization waits, etc. So these are just two ways of viewing the same data, and you’re free to choose the organization that best suits what information you are after. Analyzing Method Source If we look at the timings above, we see that our AddToList() method (and in particular, it’s call to the List<T>.Sort() method in the BCL) is the hot-spot in this analysis. If ANTS sees a method that is consuming the most time, it will flag it as a hot-spot to help call out potential areas of concern. This doesn’t mean the other statistics aren’t meaningful, but that the hot-spot is most likely going to be your biggest bang-for-the-buck to concentrate on. So let’s select the AddToList() method, and see what it shows in the source window below: Notice the source breakout in the bottom pane when you select a method (from either tree or grid view). This shows you the timings in this method per line of code. This gives you a major indicator of where the trouble-spot in this method is. So in this case, we see that performing a Sort() on the List<T> after every Add() is killing our performance! Of course, this was a very contrived, duh moment, but you’d be surprised how many performance issues become duh moments. Note that this one line is taking up 86% of the execution time of this application! If we eliminate this bottleneck, we should see drastic improvement in the performance. So to fix this, if we still wanted to maintain the List<T> we’d have many options, including: delay Sort() until after all Add() methods, using a SortedSet, SortedList, or SortedDictionary depending on which is most appropriate, or forgoing the sorting all together and using a Dictionary. Rinse, Repeat! So let’s just change all instances of List<string> to SortedSet<string> and run this again through the profiler: Now we see the AddToList() method is no longer our hot-spot, but now the Max() and Min() calls are! This is good because we’ve eliminated one hot-spot and now we can try to correct this one as well. As before, we can then optimize this part of the code (possibly by taking advantage of the fact the list is now sorted and returning the first and last elements). We can then rinse and repeat this process until we have eliminated as many bottlenecks as possible. Calls by Web Request Another feature that was added recently is the ability to view .NET methods grouped by the HTTP requests that caused them to run. This can be helpful in determining which pages, web services, etc. are causing hot spots in your web applications. Summary If you like the other ANTS tools, you’ll like the ANTS Performance Profiler as well. It is extremely easy to use with very little product knowledge required to get up and running. There are profilers built into the higher product lines of Visual Studio, of course, which are also powerful and easy to use. But for quickly jumping in and finding hot spots rapidly, Red Gate’s Performance Profiler 7.4 is an excellent choice. Technorati Tags: Influencers,ANTS,Performance Profiler,Profiler

  - by Gopinath

  I love checking AdSense earnings every day on my mobile. All these days my mobile browser, opera, rendered the heavy desktop version of AdSense interface and it was tough to navigate around and see the earnings. To solve the problems of me as well as millions of other AdSense users, Google yesterday released a mobile version of AdSense user interface that works on almost all the mobile platforms – iOS, Android, Windows Phone 7, Symbian and many others. If you have opted for the new beta user interface of AdSense, you will be presented with the mobile version when you https://www.google.com/adsense on your mobile. Here is a screen grab of how looks like on iPhone and Android device.It looks similar on my Nokia mobile too. The Adsense interface for mobile is very nice – on the home page I can quickly have a look at today’s earnings, recent payment amount, last month finalized amount and the total unpaid balances. The quick reports option available the bottom of the screen lets me access a graphical view of useful earnings reports like – Last 7 days, Last 30 days, This Month and Last Month. You can also create your own reports and save them to this list for quick viewing. To view the graphical reports, you don’t need FLASH on your mobile. For more details check out the official post on Google Adsense blog. This article titled,AdSense Mobile Interface – I’m Loving It!, was originally published at Tech Dreams.

• To 'seal' or to 'wrap': that is the question ...

  - by Simon Thorpe

  If you follow this blog you will already have a good idea of what Oracle Information Rights Management (IRM) does. By encrypting documents Oracle IRM secures and tracks all copies of those documents, everywhere they are shared, stored and used, inside and outside your firewall. Unlike earlier encryption products authorized end users can transparently use IRM-encrypted documents within standard desktop applications such as Microsoft Office, Adobe Reader, Internet Explorer, etc. without first having to manually decrypt the documents. Oracle refers to this encryption process as 'sealing', and it is thanks to the freely available Oracle IRM Desktop that end users can transparently open 'sealed' documents within desktop applications without needing to know they are encrypted and without being able to save them out in unencrypted form. So Oracle IRM provides an amazing, unprecedented capability to secure and track every copy of your most sensitive information - even enabling end user access to be revoked long after the documents have been copied to home computers or burnt to CD/DVDs. But what doesn't it do? The main limitation of Oracle IRM (and IRM products in general) is format and platform support. Oracle IRM supports by far the broadest range of desktop applications and the deepest range of application versions, compared to other IRM vendors. This is important because you don't want to exclude sensitive business processes from being 'sealed' just because either the file format is not supported or users cannot upgrade to the latest version of Microsoft Office or Adobe Reader. But even the Oracle IRM Desktop can only open 'sealed' documents on Windows and does not for example currently support CAD (although this is coming in a future release). IRM products from other vendors are much more restrictive. To address this limitation Oracle has just made available the Oracle IRM Wrapper all-format, any-platform encryption/decryption utility. It uses the same core Oracle IRM web services and classification-based rights model to manually encrypt and decrypt files of any format on any Java-capable operating system. The encryption envelope is the same, and it uses the same role- and classification-based rights as 'sealing', but before you can use 'wrapped' files you must manually decrypt them. Essentially it is old-school manual encryption/decryption using the modern classification-based rights model of Oracle IRM. So if you want to share sensitive CAD documents, ZIP archives, media files, etc. with a partner, and you already have Oracle IRM, it's time to get 'wrapping'! Please note that the Oracle IRM Wrapper is made available as a free sample application (with full source code) and is not formally supported by Oracle. However it is informally supported by its author, Martin Lambert, who also created the widely-used Oracle IRM Hot Folder automated sealing application.

• Streaming Netflix Media with My Wii

  - by Ben Griswold

  Late last year, I wrote about Streaming Media with my Sony Blu-ray Disc Player. I am still digging the Blu-ray player setup but guess what showed up in the mail yesterday?   That’s right!  A free Netflix disc which now let’s me instantly watch TV episodes and movies via my Wii console.  I popped the disc into the console and in less than 2 minutes the brain-numbingly simple activation was complete.  (Full-disclosure: I already had my Wi-Fi connection configured, but I’m confident that the Netflix installation disc would have helpfully walked me through this additional step if need be.) As it turns out, the Wii Netflix UI offers far more options than what one gets with the Blu-ray setup.  Not only can I view my Instant Queue, but there’s a list of recently watched movies, a list of recommended titles by category, the star rating system, movies information and nearly everything you find on the web.  I reread Steve Krug’s Don’t Make Me Think: A Common Sense Approach to Web Usability on a flight back from Orlando on Wednesday, so my current view of the world may be a little skewed but, the brilliance of Netflix Wii’s user interface is undeniable. It’s not like the Blu-ray navigation is complicated but the Wii navigation feels familiar and intuitive. How intuitive?  Well, you won’t find a single bit of help text on any of the Wii screens – just a simple and obvious point-and-click navigation system.  And the UI is really pretty (which is still very important if you ask me) and so easy it became fun. Did I mention the media streaming works!  Yep, we watched 2 half-hour kid videos yesterday without any streaming issues at all.  If you have a Netflix account and a Wii, order your disc and give it a go. It’s good stuff.

• Welcome to my geeks blog

  - by bconlon

  Hi and welcome! I'm Bazza and this is my geeks blog. I have 20 years Visual Studio mainly C++, MFC,  ATL and now, thankfully, C# and I am embarking on the new world (well new to me) of WPF, so I thought I would try and capture my successful...and not so successful...WPF experiences with the geek world. So where to start? WPF? What I know so far... From wiki..."Windows Presentation Foundation (or WPF) is a graphical subsystem for rendering user interfaces in Windows-based applications." Hmm, great but didn't MFC, ATL (my head hurt with that one), and .Net all have APIs to allow me to code against the Windows Graphical Device Interface (GDI)? "Rather than relying on the older GDI subsystem, WPF utilizes DirectX. WPF attempts to provide a consistent programming model for building applications and provides a separation between the user interface and the business logic." OK, different drawing code, same Windows and weren't we always taught to separate our UI, Business Layer and Data Access Layer? "WPF employs XAML, a derivative of XML, to define and link various UI elements. WPF applications can be deployed as standalone desktop programs, or hosted as an embedded object in a website." Cool, now we're getting somewhere. So when they say separation they really mean separation. The crux of this appears to be that you can have creative people writing the UI and making it attractive and intuitive to use, whist the geeks concentrate on writing the Business and Data Access stuff. XAML (eXtensible Application Markup Language) maps XML elements and attributes directly to Common Language Runtime (CLR) object instances, properties and events. True separation of the View and Model. WPF also provides logical separation of a control from its appearance. In a traditional Windows system, all Controls have a base class containing a Windows handle and each Control knows how to render itself. In WPF, the controls are more like those in a Web Browser using Cascading Style Sheet, they are not wrappers for standard Windows Controls. Instead, they have a default 'template' that defines a visual theme which can easily be replaced by a custom template. But it gets better. WPF concentrates heavily on Data Binding where the client can bind directly to data on the server. I think this concept was first introduced in 'Classic' Visual Basic, where you could bind a list directly to a data from an Access database, and you could do similar in ASP .Net. However, the WPF implementation is far superior than it's predecessors. There are also other technologies that I want to look at like LINQ and the Entity Framework, but that's all for now. #

• Work Item Visualizer for TFS 2010 - New Extension

  - by MikeParks

  I released another new extension to the Visual Studio Gallery again today called Work Item Visualizer for TFS 2010. I've only heard positive things about it so far, hopefully it stays that way :) Basically, it creates a diagram of all work items linked to a work item ID which the user specifies in a search box. This extension was coded using DGML (the same graph rendering language used for the Visual Studio 2010 Architecture Tools). It was pretty cool getting a chance to create something using some of the newest technology out there. Well, I just wanted to throw a blog up to get the word out on it a little more. If you're using Visual Studio 2010 with Team Foundation Server 2010, feel free to check it out! Thanks everyone. Download Link: http://visualstudiogallery.msdn.microsoft.com/en-us/a35b6010-750b-47f6-a7a5-41f0fa7294d2   What it does: ·         Creates a DGML graph to visualize linked TFS Work Items by entering a Work Item ID in the toolbar search box   How it benefits you: ·         Allows you to easily analyze the hierarchy of your TFS Work Items ·         Gain the ability to perform basic risk/impact analysis when creating or editing Work Items ·         Great for meetings in the case that you need to discuss the entire scope of linked Work Items ·         Easier project planning ·         Eliminates the need to create TFS queries or reports to view tree of Work Items ·         Easily lets you see the entire tree of work items linked to the one you’re working on   Navigation Tips: ·         Use Ctrl + Mouse Wheel Scroll to zoom in and out ·         Use Ctrl + Left Mouse click (and hold) to move document around ·         Right click on DGML area for more options (Like copy image or viewing in groups) ·         Clicking on each node highlights that node and the links connected to it ·         Colors in the legend can be changed ·         When work item nodes are deleted, the view is automatically updated ·         Double clicking on work item node will open up the Work Items URL   Try it out on work items that have several of links and let us know what you think. A big thanks goes out to everyone working on the http://visualization.codeplex.com/ project for publishing the source code on CodePlex which really helped me learn how DGML (Directed Graph Markup Language - New to Visual Studio 2010 Architecture Tools) works!    - Mike

• VB6 Scheduled tasks on Windows Server 2008 Standard

  - by Terry

  Hello, this is my first time using this forum. Here is my situation: We are having issues with specific tasks written in VB6 it would seem. I am not a developer, but I am told these tasks exe are written in VB6. The task is initiated by task scheduler, the process begins to run (you can view the task in task manager, but no resources are used, 00 CPU, 760 K RAM), but nothing occurs. In a normal operating situation, the task will use 25% CPU and up to 20 MB RAM. When the task fails to run, you can still end and start it via Task Scheduler, but nothing happens. If you run just the process via the exe, it runs fine. The problem just seems to be when it is initiated via Task Scheduler. And this is a random issue, which always disappears after a server reboot. All of these tasks are VB 6 applications on Windows Server 2008 Standard, some servers are SP1, some are SP2, but both versions experience the issue. The task has been configured to run with highest priviledges, and to run whether logged on or not. Setting compatibility mode on the exe to 2003 does not make a difference. Situation 1: 51 - ERROR - Program did not appear to complete, check server!! (Desc: Input past end of file) in this situation, the task is running in task scheduler and you can view the process in task manager. . In the log file, all that is logged is: 12/17/2009 03:16 Starting T2 Populator version - 1.0.12 You can just end the task via task scheduler and start it via task scheduler and away it goes Situation 2: 36 - ERROR - Program last ran on 16-Dec-2009 in this situation the task is running in Task Scheduler and you can view the process in task manager, but no resources are used, 00 CPU, 760 K RAM. Nothing is logged in the log file. You end the task via task scheduler, but you must manually run the exe for it to complete. I was wondering if anyone else has experienced issues with VB6 tasks, or any tasks for that matter, on Server 2008?

• ASP.NET Web API - Screencast series Part 2: Getting Data

  - by Jon Galloway

  We're continuing a six part series on ASP.NET Web API that accompanies the getting started screencast series. This is an introductory screencast series that walks through from File / New Project to some more advanced scenarios like Custom Validation and Authorization. The screencast videos are all short (3-5 minutes) and the sample code for the series is both available for download and browsable online. I did the screencasts, but the samples were written by the ASP.NET Web API team. In Part 1 we looked at what ASP.NET Web API is, why you'd care, did the File / New Project thing, and did some basic HTTP testing using browser F12 developer tools. This second screencast starts to build out the Comments example - a JSON API that's accessed via jQuery. This sample uses a simple in-memory repository. At this early stage, the GET /api/values/ just returns an IEnumerable<Comment>. In part 4 we'll add on paging and filtering, and it gets more interesting.   The get by id (e.g. GET /api/values/5) case is a little more interesting. The method just returns a Comment if the Comment ID is valid, but if it's not found we throw an HttpResponseException with the correct HTTP status code (HTTP 404 Not Found). This is an important thing to get - HTTP defines common response status codes, so there's no need to implement any custom messaging here - we tell the requestor that the resource the requested wasn't there.  public Comment GetComment(int id) { Comment comment; if (!repository.TryGet(id, out comment)) throw new HttpResponseException(HttpStatusCode.NotFound); return comment; } This is great because it's standard, and any client should know how to handle it. There's no need to invent custom messaging here, and we can talk to any client that understands HTTP - not just jQuery, and not just browsers. But it's crazy easy to consume an HTTP API that returns JSON via jQuery. The example uses Knockout to bind the JSON values to HTML elements, but the thing to notice is that calling into this /api/coments is really simple, and the return from the $.get() method is just JSON data, which is really easy to work with in JavaScript (since JSON stands for JavaScript Object Notation and is the native serialization format in Javascript). $(function() { $("#getComments").click(function () { // We're using a Knockout model. This clears out the existing comments. viewModel.comments([]); $.get('/api/comments', function (data) { // Update the Knockout model (and thus the UI) with the comments received back // from the Web API call. viewModel.comments(data); }); }); }); That's it! Easy, huh? In Part 3, we'll start modifying data on the server using POST and DELETE.

• Creating Limited User Accounts on Ubuntu Server

  - by LonnieBest

  Using Ubuntu server, I need to create some user accounts that have the following limitations: (1) User may only view and manipulate files in their home directory. (2) User may only execute commands related to rsync and sftp. I want users to be able to backup files using rsync, and I want them to be able retrieve files using an sftp client like FileZilla. Other than this, I don't want users to be able to view other files on the system, or execute any commands that might mess with the system. I'm more of an Ubuntu Desktop user, and have very little experience administering a linux server. Most tutorials I've found assume I know things that I don't know. So I'm having difficulty setting this up.

  I’ve posted all of my slides and samples from the DevConnections VS 2010 Launch event last week in Vegas. All three sessions are contained in a single zip file which contains all slide decks and samples in one place: www.west-wind.com/files/conferences/jquery.zip There were 3 separate sessions: Using jQuery with ASP.NET Starting with an overview of jQuery client features via many short and fun examples, you'll find out about core features like the power of selectors to select document elements, manipulate these elements with jQuery's wrapped set methods in a browser independent way, how to hook up and handle events easily and generally apply concepts of unobtrusive JavaScript principles to client scripting. The session also covers AJAX interaction between jQuery and the .NET server side code using several different approaches including sending HTML and JSON data and how to avoid user interface duplication by using client side templating. This session relies heavily on live examples and walk-throughs. jQuery Extensibility and Integration with ASP.NET Server Controls One of the great strengths of the jQuery Javascript framework is its simple, yet powerful extensibility model that has resulted in an explosion of plug-ins available for jQuery. You need it - chances are there's a plug-in for it! In this session we'll look at a few plug-ins to demonstrate the power of the jQuery plug-in model before diving in and creating our own custom jQuery plug-ins. We'll look at how to create a plug-in from scratch as well as discussing when it makes sense to do so. Once you have a plug-in it can also be useful to integrate it more seamlessly with ASP.NET by creating server controls that coordinate both server side and jQuery client side behavior. I'll demonstrate a host of custom components that utilize a combination of client side jQuery functionality and server side ASP.NET server controls that provide smooth integration in the user interface development process. This topic focuses on component development both for pure client side plug-ins and mixed mode controls. jQuery Tips and Tricks This session was kind of a last minute substitution for an ASP.NET AJAX talk. Nothing too radical here :-), but I focused on things that have been most productive for myself. Look at the slide deck for individual points and some of the specific samples.   It was interesting to see that unlike in previous conferences this time around all the session were fairly packed – interest in jQuery is definitely getting more pronounced especially with microsoft’s recent announcement of focusing on jQuery integration rather than continuing on the path of ASP.NET AJAX – which is a welcome change. Most of the samples also use the West Wind Web & Ajax Toolkit and the support tools contained within it – a snapshot version of the toolkit is included in the samples download. Specicifically a number of the samples use functionality in the ww.jquery.js support file which contains a fairly large set of plug-ins and helper functionality – most of these pieces while contained in the single file are self-contained and can be lifted out of this file (several people asked). Hopefully you'll find something useful in these slides and samples.© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET  jQuery

• dedicated server - cgi-sys/defaultwebpage.cgi redirect when accessing via server IP

  - by Ross

  Hi This isn't so much of a problem, but would like to know why this happens. we have a dedicated server running WHM. If I access the server via its IP address directly I am automatically redirected to http://xx.xxx.xx.xxx/cgi-sys/defaultwebpage.cgi I know how to edit this page (this isnt the problem) I'm just curious why I get redirected to this .cgi page, rather than simply remain @ xx.xxx.xx.xxx/ and view my default "landing page", if you like. What setting could I change so that if anyone visits my server IP, they do not get redirected to xx.xxx.xx.xxx/cgi-sys/defaultwebpage.cgi For instance if you visit 173.194.37.104 (google), you view the google home page, but URL remains the same. Hope this makes sense. thanks

• AS11 Oracle B2B Sync Support - Series 1

  - by sinkarbabu.kirubanithi

  Synchronous message support has been enabled in Oracle B2B 11G. This would help customers to send the business message and receive the corresponding business response synchronously. We would like to keep this blog entry as three part series, first one would carry Oracle B2B configuration related details followed by 'how it can be consumed and utilized in an enterprise' using composites backed model. And, the last one would talk about more sophisticated seeded support built on Oracle B2B platform (Note: the last one is still in description phase and ETA hasn't been finalized yet). Details: In an effort to enable synchronous processing in Oracle B2B, we provided a platform using the existing 'callout' mechanism. In this case, we expect the 'callout' attached to the agreement to deliver incoming business message (inbound) to back-end application and get the corresponding business response from back-end and deliver it to Oracle B2B as its output. The output of 'callout' would be processed as outbound message and the same will be attached as a response for the inbound message. Requirements to enable Sync Support: Outbound side: Outbound Agreement - to send business message request Inbound Agreement - to receive business message response Inbound side: Inbound Agreement - to receive business message request Outbound Agreement - to send business message response Agreement Level Callout - to deliver the inbound request to back-end and get the corresponding business response This feature is supported only for HTTP based transport to exchange messages with Trading Partners. One may initiate the outbound message (enqueue) using any of the available Transports in Oracle B2B. Configuration: Outbound side: Please add "syncresponse=true" as "Additional Transport Header" parameter for remote Trading Partner's HTTP delivery channel configuration. This would enable Oracle B2B to process the HTTP response as inbound message and deliver the same to back-end application. All other configuration related to Agreement and Document setup remain same. Inbound side: There is no change in Agreement and Document setup. To enable "Sync Support", you need to build a 'callout' that takes the responsibility of delivering inbound message to back-end and get the corresponding business response from the back-end and attach the same as its output. Oracle B2B treats the output of 'callout' as outbound message and deliver it to Trading Partner as synchronous HTTP response. The requests that needs to processed synchronously should be received by "syncreceiver" (http://:/b2b/syncreceiver) endpoint in Oracle B2B. Exception Handling: Existing Oracle B2B exception handling applies to this use case as well. Here's the sample callout, SampleSyncCallout.java We will get you second part that talks about 'SOA composites' backed model to design the "Sync Support" use case from back-end to Trading Partners, stay tuned.

• 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

• Accessing apache on virtual pc

  - by Rick Hensly

  I am using a virtual pc to test my website. I can access all my webpages on the virtual pc. However, images don't load correctly. I can browse to my images folder and view all of them. However, if I click an image it will not load, and the apache log shows the virtual pc's ip trying to view the image: 192.168.0.55 - - [25/Jun/2009:20:10:41 -0400] "GET /images/pic.png HTTP/1.1" 302 220 Now, if I refresh the page it loads. 192.168.0.55 - - [25/Jun/2009:20:10:51 -0400] "GET /images/bg.png HTTP/1.1" 200 214 Also, images won't load in html or css. It seems like a redirecting problem or something, but I have no clue how to fix it. Thanks for any advice

• SQL SERVER – guest User and MSDB Database – Enable guest User on MSDB Database

  - by pinaldave

  I have written a few articles recently on the subject of guest account. Here’s a quick list of these articles: SQL SERVER – Disable Guest Account – Serious Security Issue SQL SERVER – Force Removing User from Database – Fix: Error: Could not drop login ‘test’ as the user is currently logged in. SQL SERVER – Detecting guest User Permissions – guest User Access Status One of the advices which I gave in all the three blog posts was: Disable the guest user in the user-created database. Additionally, I have mentioned that one should let the user account become enabled in MSDB database. I got many questions asking if there is any specific reason why this should be kept enabled, questions like, “What is the reason that MSDB database needs guest user?” Honestly, I did not know that the concept of the guest user will create so much interest in the readers. So now let’s turn this blog post into questions and answers format. Q: What will happen if the guest user is disabled in MSDB database? A:  Lots of bad things will happen. Error 916 - Logins can connect to this instance of SQL Server but they do not have specific permissions in a database to receive the permissions of the guest user. Q: How can I determine if the guest user is enabled or disabled for any specific database? A: There are many ways to do this. Make sure that you run each of these methods with the context of the database. For an example for msdb database, you can run the following code: USE msdb; SELECT name, permission_name, state_desc FROM sys.database_principals dp INNER JOIN sys.server_permissions sp ON dp.principal_id = sp.grantee_principal_id WHERE name = 'guest' AND permission_name = 'CONNECT' There are many other methods to detect the guest user status. Read them here: Detecting guest User Permissions – guest User Access Status Q: What is the default status of the guest user account in database? A: Enabled in master, TempDb, and MSDB. Disabled in model database. Q: Why is the default status of the guest user disabled in model database? A: It is not recommended to enable the guest in user database as it can introduce serious security threat. It can seriously damage the database if configured incorrectly. Read more here: Disable Guest Account – Serious Security Issue Q: How to disable guest user? A: REVOKE CONNECT FROM guest Q: How to enable guest user? A: GRANT CONNECT TO guest Did I miss any critical question in the list? Please leave your question as a comment and I will add it to this list.
