  • Partners - Steer Clear of the Unknown with Oracle Enterprise Manager12c and Plug-in Extensibility

    - by Get_Specialized!
    Imagine if you just purchased a new car and as you entered the vehicle to drive it home and you found there was no steering wheel. And upon asking the dealer you were told that it was an option and you had a choice now or later of a variety of aftermarket steering wheels that fit a wide variety of automobiles. If you expected the car to already have a steering wheel designed to manage your transportation solution, you might wonder why someone would offer an application solution where its management is not offered as an option or come as part of the solution... Using management designed to support the underlying technology and that can provide management and support  for your own Oracle technology based solution can benefit your business  a variety of ways: increased customer satisfaction, reduction of support calls, margin and revenue growth. Sometimes when something is not included or recommended , customers take their own path which may not be optimal when using your solution and has later impact on the customers satisfaction or worse a negative impact on their business. As an Oracle Partner, you can reduce your research, certification, and time to market by selecting and offering management designed, developed, and supported for Oracle product technology by Oracle with Oracle Enterprise Manager 12c. For partners with solution specific management needs or seeking to differentiate themselves in the market, Enterprise Manager 12c is extensible and provides partners the opportunity to create their own plug-ins as well as a validation program for them.  Today a number of examples by partners are available and Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-family:"Calibri","sans-serif"; mso-ascii- mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi- mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} more on the way from such partners as NetApp for NetApp storage and Blue Medora for VMware vSphere.

  • Designing communications for extensibility

    - by Thomas S.
    I am working on the design stages of an application that will a) collect data from various sources (in my case that's scientific data from serial ports), keeping track of the age of the data, b) generate real-time statistics (e.g. running averages) c) display, record, and otherwise handle the data (and statistics). I anticipate that I will be adding both data producers and consumers over time, and would like to design this application abstractly so that I will be able to trivially add functionality with a small amount of interface code. What I'm stumbling on is deciding what communication infrastructure I should use to handle the interfaces. In particular, how should I make the processed data and statistics available to multiple consumers? Some things I've considered: Writing to several named pipes (variable number). Each consumer reads from one of them. Using FUSE to make a userspace filesystem where a read() returns the latest line of data even if another process has already read it. Making a TCP server, and having consumers connect and request data individually. Simply writing the consumers as part of the same program that aggregates the data. So I would like to hear your all's advice on deciding how to interface these functions in the best way to keep them separate and allow room for extenstions.

  • ITIL Incident Classification - Fault vs SR vs Technical Incident

    - by ExceptionLimeCat
    I am new to ITIL and Incident classifcations and I am trying learn more about them and understand how they could integrate in our organization. I have found it difficult to find a clear definition of Fault vs. Service Request vs. Technical incidents. I am basing my definitions on this article: http://www.itsmsolutions.com/newsletters/DITYvol6iss27.htm As I understand it: Service Request - Service provided by IT as part of regular administration of a system. Fault - An unexpected error in a system. Technical Incident - An interruption or potential interruption in IT service due to an expected incident caused by some IT policy.

  • Box Selection and Multi-Line Editing with VS 2010

    - by ScottGu
    This is the twenty-second in a series of blog posts I’m doing on the VS 2010 and .NET 4 release. I’ve already covered some of the code editor improvements in the VS 2010 release.  In particular, I’ve blogged about the Code Intellisense Improvements, new Code Searching and Navigating Features, HTML, ASP.NET and JavaScript Snippet Support, and improved JavaScript Intellisense.  Today’s blog post covers a small, but nice, editor improvement with VS 2010 – the ability to use “Box Selection” when performing multi-line editing.  This can eliminate keystrokes and enables some slick editing scenarios. [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] Box Selection Box selection is a feature that has been in Visual Studio for awhile (although not many people knew about it).  It allows you to select a rectangular region of text within the code editor by holding down the Alt key while selecting the text region with the mouse.  With VS 2008 you could then copy or delete the selected text. VS 2010 now enables several more capabilities with box selection including: Text Insertion: Typing with box selection now allows you to insert new text into every selected line Paste/Replace: You can now paste the contents of one box selection into another and have the content flow correctly Zero-Length Boxes: You can now make a vertical selection zero characters wide to create a multi-line insert point for new or copied text These capabilities can be very useful in a variety of scenarios.  Some example scenarios: change access modifiers (private->public), adding comments to multiple lines, setting fields, or grouping multiple statements together. Great 3 Minute Box-Selection Video Demo Brittany Behrens from the Visual Studio Editor Team has an excellent 3 minute video that shows off a few cool VS 2010 multi-line code editing scenarios with box selection:   Watch it to learn a few ways you can use this new box selection capability to optimize your typing in VS 2010 even further: Hope this helps, Scott P.S. You can learn more about the VS Editor by following the Visual Studio Team Blog or by following @VSEditor on Twitter.

  • Persisting settings without using Options dialog in Visual Studio

    - by Utkarsh Shigihalli
    Originally posted on: http://geekswithblogs.net/onlyutkarsh/archive/2013/11/02/persisting-settings-without-using-options-dialog-in-visual-studio.aspxIn one of my previous blog post we have seen persisting settings using Visual Studio's options dialog. Visual Studio options has many advantages in automatically persisting user options for you. However, during our latest Team Rooms extension development, we decided to provide our users; ability to use our preferences directly from Team Explorer. The main reason was that we had only one simple option for user and we thought it is cumbersome for user to go to Tools –> Options dialog to change this. Another reason was, we wanted to highlight this setting to user as soon as he is using our extension.   So if you are in such a scenario where you do not want to use VS options window, but still would like to persist the settings, this post will guide you through. Visual Studio SDK provides two ways to persist settings in your extensions. One is using DialogPage as shown in my previous post. Another way is to use by implementing IProfileManager interface which I will explain in this post. Please note that the class implementing IProfileManager should be independent class. This is because, VS instantiates this class during Tools –> Import and Export Settings. IProfileManager provides 2 different sets of methods (total 4 methods) to persist the settings. They are LoadSettingsFromXml and SaveSettingsToXml – Implement these methods to persist settings to disk from VS settings storage. The VS will persist your settings along with other options to disk. LoadSettingsFromStorage and SaveSettingsToStorage – Implement these methods to persist settings to local storage, usually it be registry. VS calls LoadSettingsFromStorage method when it is initializing the package too. We are going to use the 2nd set of methods for this example. First, we are creating a separate class file called UserOptions.cs. Please note that, we also need to implement IComponent, which can be done by inheriting Component along with IProfileManager. [ComVisible(true)] [Guid("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX")] public class UserOptions : Component, IProfileManager { private const string SUBKEY_NAME = "TForVS2013"; private const string TRAY_NOTIFICATIONS_STRING = "TrayNotifications"; ... } Define the property so that it can be used to set and get from other classes. public bool TrayNotifications { get; set; } Implement the members of IProfileManager. public void LoadSettingsFromStorage() { RegistryKey reg = null; try { using (reg = Package.UserRegistryRoot.OpenSubKey(SUBKEY_NAME)) { if (reg != null) { // Key already exists, so just update this setting. TrayNotifications = Convert.ToBoolean(reg.GetValue(TRAY_NOTIFICATIONS_STRING, true)); } } } catch (TeamRoomException exception) { TrayNotifications = true; ExceptionReporting.Report(exception); } finally { if (reg != null) { reg.Close(); } } } public void LoadSettingsFromXml(IVsSettingsReader reader) { reader.ReadSettingBoolean(TRAY_NOTIFICATIONS_STRING, out _isTrayNotificationsEnabled); TrayNotifications = (_isTrayNotificationsEnabled == 1); } public void ResetSettings() { } public void SaveSettingsToStorage() { RegistryKey reg = null; try { using (reg = Package.UserRegistryRoot.OpenSubKey(SUBKEY_NAME, true)) { if (reg != null) { // Key already exists, so just update this setting. reg.SetValue(TRAY_NOTIFICATIONS_STRING, TrayNotifications); } else { reg = Package.UserRegistryRoot.CreateSubKey(SUBKEY_NAME); reg.SetValue(TRAY_NOTIFICATIONS_STRING, TrayNotifications); } } } catch (TeamRoomException exception) { ExceptionReporting.Report(exception); } finally { if (reg != null) { reg.Close(); } } } public void SaveSettingsToXml(IVsSettingsWriter writer) { writer.WriteSettingBoolean(TRAY_NOTIFICATIONS_STRING, TrayNotifications ? 1 : 0); } Let me elaborate on the method implementation. The Package class provides UserRegistryRoot (which is HKCU\Microsoft\VisualStudio\12.0 for VS2013) property which can be used to create and read the registry keys. So basically, in the methods above, I am checking if the registry key exists already and if not, I simply create it. Also, in case there is an exception I return the default values. If the key already exists, I update the value. Also, note that you need to make sure that you close the key while exiting from the method. Very simple right? Accessing and settings is simple too. We just need to use the exposed property. UserOptions.TrayNotifications = true; UserOptions.SaveSettingsToStorage(); Reading settings is as simple as reading a property. UserOptions.LoadSettingsFromStorage(); var trayNotifications = UserOptions.TrayNotifications; Lastly, the most important step. We need to tell Visual Studio shell that our package exposes options using the UserOptions class. For this we need to decorate our package class with ProvideProfile attribute as below. [ProvideProfile(typeof(UserOptions), "TForVS2013", "TeamRooms", 110, 110, false, DescriptionResourceID = 401)] public sealed class TeamRooms : Microsoft.VisualStudio.Shell.Package { ... } That's it. If everything is alright, once you run the package you will also see your options appearing in "Import Export settings" window, which allows you to export your options.

  • My VS 2010 and ASP.NET 4 Talks Online

    - by ScottGu
    The past 7 years I’ve done an annual all day event in Arizona – organized by the most excellent Scott Cate (who always does a phenomenal job organizing the event and making it a great one). Earlier this month I visited and presented 4+ hours of content covering VS 2010, ASP.NET 4 and ASP.NET MVC 2.  NextSlide.com – a great .NET shop local to Arizona who has a great product for sharing presentations – volunteered to record the talks and publish them for free using their online presentation tool.  The recordings they did turned out really, really great – and their online player (which combines slides + camera of me + demos in one experience) is awesome.  Below you can watch the first two segments of my event – which cover VS 2010 and ASP.NET 4 – for free online using the NextSlide.com player experience.  I’ll post a link to my ASP.NET MVC 2 segment a little later in a separate blog post.  If you’ve never seen my present these talks before and are interested in the content then I’d recommend checking them out – as these recordings do a really good job capturing them. Part 1 - VS 2010 This is a 49 minute segment that starts the event and covers a bunch of the new improvements in VS 2010.  You can launch the presentation directly here or watch it inline below.  You can download powerpoint versions of my slides here. Part 2- ASP.NET 4 This 61 minute segment comes next and drills into some of the framework improvements with ASP.NET 4.  It also goes further on some of the web specific tooling improvements in VS 2010 – and towards the end demonstrates some of the great new end-to-end web deployment features provided with VS 2010 (which work for both ASP.NET Web Forms and ASP.NET MVC applications). You can launch the presentation directly here or watch it inline below: Learning More about VS 2010 and ASP.NET 4 I’ve been working on a series of blog post about VS 2010 and .NET 4.  Many of the features I covered in my two talks above are described in more detail in posts within the series.  You can read all of them here. I’ll be continuing adding to the series via my blog, so stay tuned for more in-depth posts about a bunch more new features. Hope this helps, Scott P.S. People often ask whether they can re-use the slides+demos I use in my talks for talks of their own.  The answer to this is always absolutely! No need to ask permission.  Feel free to re-use all of my slides for talks of your own. P.P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links.

  • Converting VS 2008 Project to VS 2010 - now .aspx won't load

    - by coffeeaddict
    I converted all my other projects fine from VS 2008 to 2010 and they run great. There is one project however for some reason after converting, when I try to run one of the .aspx pages in it, I get nothing...no error, just that it cannot display the page. Nothing has changed. The path is still the same, and the IIS website is still the same. I even recreated the site in IIS using the VS option to create it in the web project properties. This is a testing project..only has like one .aspx in it. Not sure why I get nothing after converting this. I did not convert it to .NET 4.0, it's still in v3.5 in VS 2010.

  • Some VS 2010 RC Updates (including patches for Intellisense and Web Designer fixes)

    - by ScottGu
    [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] We are continuing to make progress on shipping Visual Studio 2010.  I’d like to say a big thank you to everyone who has downloaded and tried out the VS 2010 Release Candidate, and especially to those who have sent us feedback or reported issues with it. This data has been invaluable in helping us find and fix remaining bugs before we ship the final release. Last month I blogged about a patch we released for the VS 2010 RC that fixed a bad intellisense crash issue.  This past week we released two additional patches that you can download and apply to the VS 2010 RC to immediately fix two other common issues we’ve seen people run into: Patch that fixes crashes with Tooltip invocation and when hovering over identifiers The Visual Studio team recently released a second patch that fixes some crashes we’ve seen when tooltips are displayed – most commonly when hovering over an identifier to view a QuickInfo tooltip. You can learn more about this issue from this blog post, and download and apply the patch here. Patch that fixes issues with the Web Forms designer not correctly adding controls to the auto-generated designer files The Visual Web Developer team recently released a patch that fixes issues where web controls are not correctly added to the .designer.cs file associated with the .aspx file – which means they can’t be programmed against in the code-behind file.  This issue is most commonly described as “controls are not being recognized in the code-behind” or “editing existing .aspx files regenerates the .aspx.designer.(vb or cs) file and controls are now missing” or “I can’t embed controls within the Ajax Control Toolkit TabContainer or the <asp:createuserwizard> control”. You can learn more about the issue here, and download the patch that fixes it here. Common Cause of Intellisense and IDE sluggishness on Windows XP, Vista, Win Server 2003/2008 systems Over the last few months we’ve occasionally seen reports of people seeing tremendous slowness when typing and using intellisense within VS 2010 despite running on decent machines.  It took us awhile to track down the cause – but we have found that the common culprit seems to be that these machines don’t have the latest versions of the UIA (Windows Automation) component installed. UIA 3 ships with Windows 7, and is a recommended Windows Update patch on XP and Vista (which is why we didn’t see the problem in our tests – since our machines are patched with all recommended updates).  Many systems (especially on XP) don’t automatically install recommended updates, though, and are running with older versions of UIA. This can cause significant performance slow-downs within the VS 2010 editor when large lists are displayed (for example: with intellisense). If you are running on Windows XP, Vista, or Windows Server 2003 or 2008 and are seeing any performance issues with the editor or IDE, please install the free UIA 3 update that can be downloaded from this page.  If you scroll down the page you’ll find direct links to versions for each OS. Note that we are making improvements to the final release of VS 2010 so that we don’t have big perf issues when UIA 3 isn’t installed – and we are also adding a message within the IDE that will warn you if you don’t have UIA 3 installed and accessibility is activated. Improved Text Rendering with WPF 4 and VS 2010 We recently made some nice changes to WPF 4 which improve the text clarity and text crispness over what was in the VS 2010/.NET 4 Release Candidate.  In particular these changes improve scenarios where you have a dark background with light text. You can learn more about these improvements in this WPF Team blog post.  These changes will be in the final release of VS 2010 and .NET 4. Hope this helps, Scott

  • I'm new to OOP/PHP. What's the practicality of visibility and extensibility in classes?

    - by marcdev
    I'm obviously brand new to these concepts. I just don't understand why you would limit access to properties or methods. It seems that you would just write the code according to intended results. Why would you create a private method instead of simply not calling that method? Is it for iterative object creation (if I'm stating that correctly), a multiple developer situation (don't mess up other people's work), or just so you don't mess up your own work accidentally?

  • Apache log rotation: logrotate vs rotatelogs vs chronolog

    - by Enrico
    I have been researching log rotation for my server which hosts ~5 fairly high traffic sites. From what I can tell, my options are to use logrotate or to use piped logging with either rotatelogs or chronolog. logrotate requires a restart of apache and both SIGHUP and SIGUSR1 restarts are less than ideal on high traffic sites, because either you drop a bunch of connections or you need to delay compressing the old log until all child processes have died naturally. Also, downtime can be quite significant if compression is enabled. Would using logrotate - without compression and with graceful restart - and compressing old logs after the fact be the best way to minimize downtime? chronolog and rotatelogs sound promising, but are not well documented. I couldn't find examples of using either in combination with vhost specific logs. The chronolog website says, "when the expanded filename changes, the current file is closed and a new one opened". Is this globally? Or is that per AccessLog, CustomLog or ErrorLog directive? Is there a significant difference between chronolog and rotatelogs?

  • SAS vs Near-line SAS vs SATA

    - by David
    I'm unsure about the differences in these storage interfaces. My Dell servers all have SAS RAID controllers in them and they seem to be cross-compatible to an extent. The Ultra-320 SCSI RAID controllers in my old servers were simple enough: One type of interface (SCA) with special drives with special controllers, humming at 10-15K RPM. But these SAS/SATA drives seem like the drives I have in my desktop, only more expensive. Also my old SCSI controllers have their own battery backup and DDR buffer - neither of these things are present on the SAS controllers. What's up with that? "Enterprise" SATA drives are compatible with my SAS RAID controller, but I'd like to know what advantage SAS drives have over SATA drives as they seem to have similar specs (but one is a lot cheaper). Also, how do SSDs fit into this? I remember when RAID controllers required HDDs to spin at the same rate (as if the controller card supplanted the controller in the drive) - so how does that work out now? And what's the deal with Near-line SATA? I apologise about the rambling tone in this message, it's 5am and I haven't slept much.

  • Laptop choice for development: MacBook Pro 17 vs Dell Studio XPS 16 vs HP Envy 15

    - by Shalan
    Hey! First things first - let me state that I am not intending to play games on this - I have narrowed down to these 3 purely based on specs and its individual brand reliability in the market. I intend to primarily use: Visual Studio 2008 Pro a lot (develop and deploy on Windows platforms) SQL Server 2005 Oracle 10g Adobe Photoshop CS4 Microsoft Expression Studio Google Sketchup I currently use a desktop PC (Core2Duo 2.66Ghz with 3GB DDRII memory) running Vista Business 32-bit - and I have to admit that, especially for Visual Studio, its quite sluggish to a point where it affects productivity. Furthermore, I intend to only use the notebook on a table - with a cooled surface, like granite :) - so I would appreciate people's input with regard to heat issues. Im aware that the Dell's primary exhaust gets blocked by the lid when open, but some reviews don't seem to place extraordinary emphasis on heat issues resulting from this. My options for the Dell/Alienware: Core i7 720QM 4GB DDRIII memory ATI mobility 3670 (512) 128GB Solid State Drive 16-inch Full HD RGB-LED LCD display (1080p) 3-year next-business-day support My configuration for the Apple MBP: Core2Duo 2.8Ghz (Im assuming the T9600) 4GB DDRIII memory 128GB Solid State Drive standard 1 year support The one advantage I think of with the MBP is that I can have the addition of OSX (though Im unsure what I would use it for, but purely to play around with a much-boasted-about OS) What are your thoughts on this, especially regarding build-quality, heat, performance and battery-life? Much thanks! ~shalan

  • Socket 1155 vs 2011 vs Haswell

    - by woody
    The title says it all. I am trying to decide between sockets and just cant pinpoint which to get based on pros and cons. The build this will go into will be my primary PC. It will be used for every day computing, coding, some multimedia and gaming. I have read that 1155 and 2011 will be dead within the new year and that Haswell will double the performance of Ivy Bridge. What is a general run down on the different sockets? Pros and Cons? More specifically what are the technical differences between the three?
