• MySQL InnoDB Corruption after power outage, possible to recover?

  - by Tim Hackett

  Hey Guys, I recently started trying to get Redmine up and running after a power outage that seems to have corrupted our InnoDB database in MySQL. Redmine had an extensive set of documentation that I would like to get even if redmine isn't able to run. The service fails on startup. I have tried inserting innodb_force_recovery = 4 per the documentation from the url in the error log. (also tried 1 thru 6 as I have backed up all directories after the corruption) I have verified through "mysqld-nt --print-defaults" that it is starting with the recovery option in the params. The machine is running Windows Server 2003 SP2, Xeon E5335 with 2GB RAM, MySQL is not mirrored to another machine, nor is the machine a mirror. I do not have any backups because the previous person did not set them up. Here is the error log: InnoDB: The log sequence number in ibdata files does not match InnoDB: the log sequence number in the ib_logfiles! 100308 14:50:01 InnoDB: Database was not shut down normally!

• Additional options in MDL

  - by Jane Zhang

      The Metadata Loader(MDL) enables you to populate a new repository as well as transfer, update, or restore a backup of existing repository metadata. It consists of two utilities: metadata export and metadata import. The export utility extracts metadata objects from a repository and writes the information into a file. The import utility reads the metadata information from an exported file and inserts the metadata objects into a repository.      While the Design Client provides an intuitive UI that helps you perform the most commonly used export and import tasks, OMBPlus scripting enables you to specify some additional options, and manage a control file that allows you to perform more specialized export and import tasks. Is it possible to utilize these options in MDL from Design Client? This article will tell you how to achieve it.      A property file named mdl.properties is used to configure the additional options. It stores options in name/value pairs. This file can be created and placed under the directory <owb installation path>/owb/bin/admin/. Below we will introduce the options that can be specified in the mdl.properties file. 1. DEFAULTDIRECTORY     When we open a Metadata Export/Import dialog in Design Client, a default directory is provided for MDL file and log file. For MDL Export, the default directory is <owb installation path>/owb/bin/. As for MDL Import, the default directory is <owb installation path>/owb/mdl/. It may not be the one you would want to use as a default. You can specify the option DEFAULTDIRECTORY in the mdl.properties file to set your own default directory for MDL Export/Import, for example, DEFAULTDIRECOTRY=/tmp/     In this example, the default directory is set to /tmp/. Be sure the value ends with a file separator since it represents a directory. In Windows, the file separator is “\”. In linux, the file separator is “/”. 2. MDLTRACEFILE     Sometimes we would like to trace the whole process of MDL Export/Import, and get detailed information about operations to help developers or supports troubleshooting. To turn on MDL trace, set the option MDLTRACEFILE in the mdl.properties file. MDLTRACEFILE=/tmp/mdl.trc    The right side of the equals sign is to specify the name of the file for MDL trace information to be written. If no path is specified, the file will be placed under directory <owb installation path>/owb/bin/admin/. However, the trace file may be large if the MDL file contains a large number of metadata objects, so please use this option sparingly. 3. CONTROLFILE       We can use a control file to specify how objects are imported or exported. We can set an option called CONTROLFILE in the mdl.properties file, so the control file can also be utilized in Design Client, for example, CONTROLFILE=/tmp/mdl_control_file.ctl     The control file stores options in name/value pairs. When using control file, be sure the file exists, otherwise an exception java.lang.Exception: CNV0002-0031(ERROR): Cannot find specified file will be thrown out during MDL Export/Import.      Next we will introduce some options specified in control file. ZIPFILEFORMAT     By default, MDL exports objects into a zip format file. This zip file has an .mdl extension and contains two files. For example, you export the repository metadata into a file called projects.mdl. When you unzip this MDL file, you obtain two files. The file projects.mdx contains the repository objects. The file mdlcatalog.xml contains internal information about the MDL XML file. Another choice is to combine these two files into one unzip text format file when doing MDL exporting.    In OMBPlus command related to MDL, there is an option called FILE_FORMAT which is used to specify the file format for the exported file. Its acceptable values are ZIP or TEXT. When the value TEXT is selected, the exported file is in text format, for example, OMBEXPORT MDL_FILE '/tmp/options_file_format_test.mdl' FILE_FORMAT TEXT FROM PROJECT 'MY_PROJECT'    How to achieve this via Design Client when doing an MDL exporting? Here we have another option called ZIPFILEFORMAT which has the same function as the FILE_FORMAT. The difference is the acceptable values for ZIPFILEFORMAT are Y or N. When the value is set to N, the exported file is in text format, otherwise it is in zip file format. LOGMESSAGELEVEL     Whenever you export or import repository metadata, MDL writes diagnostic and statistical information to a log file. Their are 3 types of status messages: Informational, Warning and Error. By default, the log file includes all types of message. Sometimes, user may only care about one type of messages, for example, they would like only error messages written to the log file. In order to achieve this, we can set an option called LOGMESSAGELEVEL in control file. The acceptable values for LOGMESSAGELEVEL are ALL, WARNING and ERROR. ALL: If the option LOGMESSAGELEVEL is set to ALL, all types of messages (Informational, Warning and Error) will be written into the log file. WARNING: If the option LOGMESSAGELEVEL is set to WARNING, only warning messages will be written into log file. ERROR: If the option LOGMESSAGELEVEL is set to ERROR, only error messages will be written into log file. UPDATEPROJECTATTRIBUTES, UPDATEMODULEATTRIBUTES      These two options are used to decide whether updating the attributes of projects/modules. The options work when projects/modules being imported already exist in repository and we use update metadata mode or replace metadata mode to do the MDL import. The acceptable values for these two options are Y or N. If the value is set to Y, the attributes of projects/modules will be updated, otherwise not.      Next, let’s give an example to see how these options take effect in MDL. 1. First of all, create the property file mdl.properties under the directory <owb installation path>/owb/bin/admin/. 2. Specify the options in the mdl.properties file, see the following screenshot. 3. Create the control file mdl_control_file.ctl under the directory /tmp/. Set the following options in control file. 4. Log into the OWB Design Client. 5. Create an Oracle module named ORA_MOD_1 under the project MY_PROJECT, then export the project MY_PROJECT into file my_project.mdl. 6. Check the trace file mdl.trc under the directory /tmp/. In this file, we can see very detail information for the above export task. 7. Check the exported MDL file. The file my_project.mdl is in text format. Opening the file, you can see the content of the file directly. It concats the file my_project.mdx and mdlcatalog.xml. 8. Modify the project MY_PROJECT and Oracle module ORA_MOD_1, add descriptions for them separately. Delete the location created in step 5. 9. Import the MDL file my_project.mdl. From the Metadata Import dialog, we can see the default directory for MDL file and log file has been changed to /tmp/. Here we use update metadata mode, match by names to do the importing. 10. After importing, check the description of the project MY_PROJECT, we can see the description is still there. But the description of the Oracle module ORA_MOD_1 has gone. That because we set the option UPDATEPROJECTATTRIBUTES to N, and set the option UPDATEMODULEATTRIBUTES to Y. 11. Check the log file, the log file only contains warning messages and the log message level is set to WARNING.      For more details about the 3 types of status messages, see Oracle® Warehouse Builder Installation and Administration Guide11g Release 2.

• Making Sense of ASP.NET Paths

  - by Renso

  Making Sense of ASP.NET Paths ASP.Net includes quite a plethora of properties to retrieve path information about the current request, control and application. There's a ton of information available about paths on the Request object, some of it appearing to overlap and some of it buried several levels down, and it can be confusing to find just the right path that you are looking for. To keep things straight I thought it a good idea to summarize the path options along with descriptions and example paths. I wrote a post about this a long time ago in 2004 and I find myself frequently going back to that page to quickly figure out which path I’m looking for in processing the current URL. Apparently a lot of people must be doing the same, because the original post is the second most visited even to this date on this blog to the tune of nearly 500 hits per day. So, I decided to update and expand a bit on the original post with a little more information and clarification based on the original comments. Request Object Paths Available Here's a list of the Path related properties on the Request object (and the Page object). Assume a path like http://www.west-wind.com/webstore/admin/paths.aspx for the paths below where webstore is the name of the virtual. Request Property Description and Value ApplicationPath Returns the web root-relative logical path to the virtual root of this app. /webstore/ PhysicalApplicationPath Returns local file system path of the virtual root for this app. c:\inetpub\wwwroot\webstore PhysicalPath Returns the local file system path to the current script or path. c:\inetpub\wwwroot\webstore\admin\paths.aspx Path FilePath CurrentExecutionFilePath All of these return the full root relative logical path to the script page including path and scriptname. CurrentExcecutionFilePath will return the ‘current’ request path after a Transfer/Execute call while FilePath will always return the original request’s path. /webstore/admin/paths.aspx AppRelativeCurrentExecutionFilePath Returns an ASP.NET root relative virtual path to the script or path for the current request. If in  a Transfer/Execute call the transferred Path is returned. ~/admin/paths.aspx PathInfo Returns any extra path following the script name. If no extra path is provided returns the root-relative path (returns text in red below). string.Empty if no PathInfo is available. /webstore/admin/paths.aspx/ExtraPathInfo RawUrl Returns the full root relative URL including querystring and extra path as a string. /webstore/admin/paths.aspx?sku=wwhelp40 Url Returns a fully qualified URL including querystring and extra path. Note this is a Uri instance rather than string. http://www.west-wind.com/webstore/admin/paths.aspx?sku=wwhelp40 UrlReferrer The fully qualified URL of the page that sent the request. This is also a Uri instance and this value is null if the page was directly accessed by typing into the address bar or using an HttpClient based Referrer client Http header. http://www.west-wind.com/webstore/default.aspx?Info Control.TemplateSourceDirectory Returns the logical path to the folder of the page, master or user control on which it is called. This is useful if you need to know the path only to a Page or control from within the control. For non-file controls this returns the Page path. /webstore/admin/ As you can see there’s a ton of information available there for each of the three common path formats: Physical Path is an OS type path that points to a path or file on disk. Logical Path is a Web path that is relative to the Web server’s root. It includes the virtual plus the application relative path. ~/ (Root-relative) Path is an ASP.NET specific path that includes ~/ to indicate the virtual root Web path. ASP.NET can convert virtual paths into either logical paths using Control.ResolveUrl(), or physical paths using Server.MapPath(). Root relative paths are useful for specifying portable URLs that don’t rely on relative directory structures and very useful from within control or component code. You should be able to get any necessary format from ASP.NET from just about any path or script using these mechanisms. ~/ Root Relative Paths and ResolveUrl() and ResolveClientUrl() ASP.NET supports root-relative virtual path syntax in most of its URL properties in Web Forms. So you can easily specify a root relative path in a control rather than a location relative path: <asp:Image runat="server" ID="imgHelp" ImageUrl="~/images/help.gif" /> ASP.NET internally resolves this URL by using ResolveUrl("~/images/help.gif") to arrive at the root-relative URL of /webstore/images/help.gif which uses the Request.ApplicationPath as the basepath to replace the ~. By convention any custom Web controls also should use ResolveUrl() on URL properties to provide the same functionality. In your own code you can use Page.ResolveUrl() or Control.ResolveUrl() to accomplish the same thing: string imgPath = this.ResolveUrl("~/images/help.gif"); imgHelp.ImageUrl = imgPath; Unfortunately ResolveUrl() is limited to WebForm pages, so if you’re in an HttpHandler or Module it’s not available. ASP.NET Mvc also has it’s own more generic version of ResolveUrl in Url.Decode: <script src="<%= Url.Content("~/scripts/new.js") %>" type="text/javascript"></script> which is part of the UrlHelper class. In ASP.NET MVC the above sort of syntax is actually even more crucial than in WebForms due to the fact that views are not referencing specific pages but rather are often path based which can lead to various variations on how a particular view is referenced. In a Module or Handler code Control.ResolveUrl() unfortunately is not available which in retrospect seems like an odd design choice – URL resolution really should happen on a Request basis not as part of the Page framework. Luckily you can also rely on the static VirtualPathUtility class: string path = VirtualPathUtility.ToAbsolute("~/admin/paths.aspx"); VirtualPathUtility also many other quite useful methods for dealing with paths and converting between the various kinds of paths supported. One thing to watch out for is that ToAbsolute() will throw an exception if a query string is provided and doesn’t work on fully qualified URLs. I wrote about this topic with a custom solution that works fully qualified URLs and query strings here (check comments for some interesting discussions too). Similar to ResolveUrl() is ResolveClientUrl() which creates a fully qualified HTTP path that includes the protocol and domain name. It’s rare that this full resolution is needed but can be useful in some scenarios. Mapping Virtual Paths to Physical Paths with Server.MapPath() If you need to map root relative or current folder relative URLs to physical URLs or you can use HttpContext.Current.Server.MapPath(). Inside of a Page you can do the following: string physicalPath = Server.MapPath("~/scripts/ww.jquery.js")); MapPath is pretty flexible and it understands both ASP.NET style virtual paths as well as plain relative paths, so the following also works. string physicalPath = Server.MapPath("scripts/silverlight.js"); as well as dot relative syntax: string physicalPath = Server.MapPath("../scripts/jquery.js"); Once you have the physical path you can perform standard System.IO Path and File operations on the file. Remember with physical paths and IO or copy operations you need to make sure you have permissions to access files and folders based on the Web server user account that is active (NETWORK SERVICE, ASPNET typically). Note the Server.MapPath will not map up beyond the virtual root of the application for security reasons. Server and Host Information Between these settings you can get all the information you may need to figure out where you are at and to build new Url if necessary. If you need to build a URL completely from scratch you can get access to information about the server you are accessing: Server Variable Function and Example SERVER_NAME The of the domain or IP Address wwww.west-wind.com or 127.0.0.1 SERVER_PORT The port that the request runs under. 80 SERVER_PORT_SECURE Determines whether https: was used. 0 or 1 APPL_MD_PATH ADSI DirectoryServices path to the virtual root directory. Note that LM typically doesn’t work for ADSI access so you should replace that with LOCALHOST or the machine’s NetBios name. /LM/W3SVC/1/ROOT/webstore Request.Url and Uri Parsing If you still need more control over the current request URL or  you need to create new URLs from an existing one, the current Request.Url Uri property offers a lot of control. Using the Uri class and UriBuilder makes it easy to retrieve parts of a URL and create new URLs based on existing URL. The UriBuilder class is the preferred way to create URLs – much preferable over creating URIs via string concatenation. Uri Property Function Scheme The URL scheme or protocol prefix. http or https Port The port if specifically specified. DnsSafeHost The domain name or local host NetBios machine name www.west-wind.com or rasnote LocalPath The full path of the URL including script name and extra PathInfo. /webstore/admin/paths.aspx Query The query string if any ?id=1 The Uri class itself is great for retrieving Uri parts, but most of the properties are read only if you need to modify a URL in order to change it you can use the UriBuilder class to load up an existing URL and modify it to create a new one. Here are a few common operations I’ve needed to do to get specific URLs: Convert the Request URL to an SSL/HTTPS link For example to take the current request URL and converted  it to a secure URL can be done like this: UriBuilder build = new UriBuilder(Request.Url); build.Scheme = "https"; build.Port = -1; // don't inject portUri newUri = build.Uri; string newUrl = build.ToString(); Retrieve the fully qualified URL without a QueryString AFAIK, there’s no native routine to retrieve the current request URL without the query string. It’s easy to do with UriBuilder however: UriBuilder builder = newUriBuilder(Request.Url); builder.Query = ""; stringlogicalPathWithoutQuery = builder.ToString();

• C#/.NET Little Wonders: The EventHandler and EventHandler&lt;TEventArgs&gt; delegates

  - by James Michael Hare

  Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. In the last two weeks, we examined the Action family of delegates (and delegates in general), and the Func family of delegates and how they can be used to support generic, reusable algorithms and classes. So this week, we are going to look at a handy pair of delegates that can be used to eliminate the need for defining custom delegates when creating events: the EventHandler and EventHandler<TEventArgs> delegates. Events and delegates Before we begin, let’s quickly consider events in .NET.  According to the MSDN: An event in C# is a way for a class to provide notifications to clients of that class when some interesting thing happens to an object. So, basically, you can create an event in a type so that users of that type can subscribe to notifications of things of interest.  How is this different than some of the delegate programming that we talked about in the last two weeks?  Well, you can think of an event as a special access modifier on a delegate.  Some differences between the two are: Events are a special access case of delegates They behave much like delegates instances inside the type they are declared in, but outside of that type they can only be (un)subscribed to. Events can specify add/remove behavior explicitly If you want to do additional work when someone subscribes or unsubscribes to an event, you can specify the add and remove actions explicitly. Events have access modifiers, but these only specify the access level of those who can (un)subscribe A public event, for example, means anyone can (un)subscribe, but it does not mean that anyone can raise (invoke) the event directly.  Events can only be raised by the type that contains them In contrast, if a delegate is visible, it can be invoked outside of the object (not even in a sub-class!). Events tend to be for notifications only, and should be treated as optional Semantically speaking, events typically don’t perform work on the the class directly, but tend to just notify subscribers when something of note occurs. My basic rule-of-thumb is that if you are just wanting to notify any listeners (who may or may not care) that something has happened, use an event.  However, if you want the caller to provide some function to perform to direct the class about how it should perform work, make it a delegate. Declaring events using custom delegates To declare an event in a type, we simply use the event keyword and specify its delegate type.  For example, let’s say you wanted to create a new TimeOfDayTimer that triggers at a given time of the day (as opposed to on an interval).  We could write something like this: 1: public delegate void TimeOfDayHandler(object source, ElapsedEventArgs e); 2:  3: // A timer that will fire at time of day each day. 4: public class TimeOfDayTimer : IDisposable 5: { 6: // Event that is triggered at time of day. 7: public event TimeOfDayHandler Elapsed; 8:  9: // ... 10: } The first thing to note is that the event is a delegate type, which tells us what types of methods may subscribe to it.  The second thing to note is the signature of the event handler delegate, according to the MSDN: The standard signature of an event handler delegate defines a method that does not return a value, whose first parameter is of type Object and refers to the instance that raises the event, and whose second parameter is derived from type EventArgs and holds the event data. If the event does not generate event data, the second parameter is simply an instance of EventArgs. Otherwise, the second parameter is a custom type derived from EventArgs and supplies any fields or properties needed to hold the event data. So, in a nutshell, the event handler delegates should return void and take two parameters: An object reference to the object that raised the event. An EventArgs (or a subclass of EventArgs) reference to event specific information. Even if your event has no additional information to provide, you are still expected to provide an EventArgs instance.  In this case, feel free to pass the EventArgs.Empty singleton instead of creating new instances of EventArgs (to avoid generating unneeded memory garbage). The EventHandler delegate Because many events have no additional information to pass, and thus do not require custom EventArgs, the signature of the delegates for subscribing to these events is typically: 1: // always takes an object and an EventArgs reference 2: public delegate void EventHandler(object sender, EventArgs e) It would be insane to recreate this delegate for every class that had a basic event with no additional event data, so there already exists a delegate for you called EventHandler that has this very definition!  Feel free to use it to define any events which supply no additional event information: 1: public class Cache 2: { 3: // event that is raised whenever the cache performs a cleanup 4: public event EventHandler OnCleanup; 5:  6: // ... 7: } This will handle any event with the standard EventArgs (no additional information).  But what of events that do need to supply additional information?  Does that mean we’re out of luck for subclasses of EventArgs?  That’s where the generic for of EventHandler comes into play… The generic EventHandler<TEventArgs> delegate Starting with the introduction of generics in .NET 2.0, we have a generic delegate called EventHandler<TEventArgs>.  Its signature is as follows: 1: public delegate void EventHandler<TEventArgs>(object sender, TEventArgs e) 2: where TEventArgs : EventArgs This is similar to EventHandler except it has been made generic to support the more general case.  Thus, it will work for any delegate where the first argument is an object (the sender) and the second argument is a class derived from EventArgs (the event data). For example, let’s say we wanted to create a message receiver, and we wanted it to have a few events such as OnConnected that will tell us when a connection is established (probably with no additional information) and OnMessageReceived that will tell us when a new message arrives (probably with a string for the new message text). So for OnMessageReceived, our MessageReceivedEventArgs might look like this: 1: public sealed class MessageReceivedEventArgs : EventArgs 2: { 3: public string Message { get; set; } 4: } And since OnConnected needs no event argument type defined, our class might look something like this: 1: public class MessageReceiver 2: { 3: // event that is called when the receiver connects with sender 4: public event EventHandler OnConnected; 5:  6: // event that is called when a new message is received. 7: public event EventHandler<MessageReceivedEventArgs> OnMessageReceived; 8:  9: // ... 10: } Notice, nowhere did we have to define a delegate to fit our event definition, the EventHandler and generic EventHandler<TEventArgs> delegates fit almost anything we’d need to do with events. Sidebar: Thread-safety and raising an event When the time comes to raise an event, we should always check to make sure there are subscribers, and then only raise the event if anyone is subscribed.  This is important because if no one is subscribed to the event, then the instance will be null and we will get a NullReferenceException if we attempt to raise the event. 1: // This protects against NullReferenceException... or does it? 2: if (OnMessageReceived != null) 3: { 4: OnMessageReceived(this, new MessageReceivedEventArgs(aMessage)); 5: } The above code seems to handle the null reference if no one is subscribed, but there’s a problem if this is being used in multi-threaded environments.  For example, assume we have thread A which is about to raise the event, and it checks and clears the null check and is about to raise the event.  However, before it can do that thread B unsubscribes to the event, which sets the delegate to null.  Now, when thread A attempts to raise the event, this causes the NullReferenceException that we were hoping to avoid! To counter this, the simplest best-practice method is to copy the event (just a multicast delegate) to a temporary local variable just before we raise it.  Since we are inside the class where this event is being raised, we can copy it to a local variable like this, and it will protect us from multi-threading since multicast delegates are immutable and assignments are atomic: 1: // always make copy of the event multi-cast delegate before checking 2: // for null to avoid race-condition between the null-check and raising it. 3: var handler = OnMessageReceived; 4: 5: if (handler != null) 6: { 7: handler(this, new MessageReceivedEventArgs(aMessage)); 8: } The very slight trade-off is that it’s possible a class may get an event after it unsubscribes in a multi-threaded environment, but this is a small risk and classes should be prepared for this possibility anyway.  For a more detailed discussion on this, check out this excellent Eric Lippert blog post on Events and Races. Summary Generic delegates give us a lot of power to make generic algorithms and classes, and the EventHandler delegate family gives us the flexibility to create events easily, without needing to redefine delegates over and over.  Use them whenever you need to define events with or without specialized EventArgs.   Tweet Technorati Tags: .NET, C#, CSharp, Little Wonders, Generics, Delegates, EventHandler

• Jenkins—get "Build Time Trend" values using "Remote Access API"

  - by Chathura Kulasinghe

  Is there a way that we can get all Jenkins-"Build Time Trend" information ( Build number + Status[success/failed etc] + Duration ) for an application; using the Jenkins remote access API? Or else I would appreciate if you could post a link of any documentation on how to get information from Jenkins using the Remote Access API. Most of the sources consist of the way of running jobs, but I couldn't find any, which shows how to fetch information from jenkins. Thanks!

• Essential management tools for a small/medium software development shop

  - by mikera

  I've recently started work with an organisation that is rapidly expanding and is recruiting or growing several development teams (including two web-based products and a data warehouse/BI team). They are basically working to agile methodologies but haven't formalised a standard way of working yet. Despite the fact that it is early days, I've been surprised by the lack of tools being used to manage the development processes (e.g. no issue tracker, no tool to manage the product backlog etc.) Although it's not my primary responsibility, I'd like to help them out with some recommendations on the most important tools they should get in place. What are the 3-5 top priority tools to establish for management of a good development shop? Why are they necessary? How do they improve the software development process, and how do I justify them to my bosses?

• Recent Innovations to ILOM

  - by B.Koch

  by Josh Rosen If you are wondering how Oracle can make some of the most advanced, reliable, and fault tolerant servers on the market, look no further than Oracle Integrated Lights Out Manager or ILOM.  We build ILOM into every server we create, from Oracle x86 Systems such as X3-2 to the SPARC T-Series family. Oracle ILOM is an embedded service processor, but it's really more than that.  It's a computer within a computer.  It's smart, it's tightly integrated into all aspects of the server's operation, and it's a big reason why Oracle servers are used for some of the most mission-critical workloads out there. To understand the value of ILOM, there is no better place to start than its fault management capability.  We have taken the sophisticated fault management architecture from Solaris, developed and refined over a decade, and built it into each and every ILOM. ILOM detects a potential issue at its earliest stage, watching low-level sensors.   If the root cause of a problem is not clear from a single error reading, ILOM will look for other clues and combine multiple pieces of information to correctly identify a failing component. ILOM provides peace of mind. We tailor our fault management for each new server platform that we produce.  You can rest assured that it's always actively keeping the server healthy.  And if there is a problem, you can be confident it will let you know by sending you a notification by e-mail or trap. We also heard IT managers tell us they needed a Ph.D. in computer engineering to manage today's servers. It doesn't have to be that way.  Thanks to the latest innovations to Oracle ILOM, we present hardware inventory and status in way that makes sense – to anyone.  Green means everything is healthy and red means something is wrong.  When a component needs to be replaced a clear message indicates where the problem is and points you at a knowledge article about that problem.  It's that simple. Simpler management and simple interfaces mean reduced complexity and lower costs to manage.  And we know that's really important. ILOM does all this while also providing advanced service processor features you depend on for managing enterprise class systems.  You can remotely control the server power, interact with a virtual video console for the server, and mount media on the server remotely.  There is no need to spend money on a KVM switch to get this functionality. And when people hear how advanced ILOM is, they can't believe ILOM is free.  All features are enabled and included with each Oracle server that you buy.  There are no advanced licenses you need to purchase or features to unlock. Configuring ILOM has also never been easier.  It is now possible to configure almost all aspects of the server directly from ILOM.  This includes changing BIOS settings, persistently modifying boot order, and optimizing power settings -- all directly from ILOM. But Oracle's innovation does not stop with ILOM.  Oracle has engineered Oracle Enterprise Manager Ops Center to integrate directly with ILOM, providing centralized management across all of our servers. Ops Center will discover each of your Oracle servers over the network by searching for ILOMs.  When it finds one, it knows how to communicate with ILOM to monitoring and configure that server from application to disk. Since every server that Oracle produces, from x86 Systems to SPARC T-Series up and down the line, comes with Oracle ILOM, you can manage all Oracle servers in the same way.  And while all of our servers may have different components on the inside, each with their specialized functions, the way you integrate them and the way you monitor and manage them is exactly the same. Oracle ILOM is state-of-art.  If you are looking for a server that make systems management simple and is easy to integrate and maintain, check out the latest advances to Oracle ILOM. Josh Rosen is a Principal Product Manager at Oracle and previously spent more than a decade as a developer and architect of system management software. Josh has worked on system management for many of Oracle's hardware products ranging from the earliest blade systems to the latest Oracle x86 servers.

• Multi page forms on ASP.NET MVC

  - by Jay

  Hi, I have decided to use ASP.NET MVC to develop multi page (registration) forms in asp.net. There will be two buttons on each page that allows the user to navigate to the previous and next page. When the user navigates back to a page they recently filled out, the data should be displayed to them. I understand ASP.NET MVC should remain stateless but how should I maintain page information when the user navigates back and forth. Should I? Save the information to a database and retrieve information for each page change? save information to the session? Load all the fields and display only whats's needed with javascript? This registration form is going to be used in multiple sites but with different sets of questions (Some may be the same). IF performance is a main concern, should I avoid generating these forms dynamically? Jay

• Create user in Oracle 11g with same priviledges as in Oracle 10g XE

  - by Álvaro G. Vicario

  I'm a PHP developer (not a DBA) and I've been working with Oracle 10g XE for a while. I'm used to XE's simplified user management: Go to Administration/ Users/ Create user Assign user name and password Roles: leave the default ones (connect and resource) Privileges: click on "Enable all" to select the 11 possible ones Create This way I get a user that has full access to its data and no access to everything else. This is fine since I only need it to develop my app. When the app is to be deployed, the client's DBAs configure the environment. Now I have to create users in a full Oracle 11g server and I'm completely lost. I have a new concept (profiles) and there're like 20 roles and hundreds of privileges in various categories. What steps do I need to complete in Oracle Enterprise Manager in order to obtain a user with the same privileges I used to assign in XE? ==== UPDATE ==== I think I'd better provide a detailed explanation so I make myself clearer. This is how I create a user in 10g XE: Roles: [X] CONNECT [X] RESOURCE [ ] DBA Direct Asignment System Privileges: [ ] CREATE DATABASE LINK [ ] CREATE MATERIALIZED VIEW [ ] CREATE PROCEDURE [ ] CREATE PUBLIC SYNONYM [ ] CREATE ROLE [ ] CREATE SEQUENCE [ ] CREATE SYNONYM [ ] CREATE TABLE [ ] CREATE TRIGGER [ ] CREATE TYPE [ ] CREATE VIEW I click on Enable All and I'm done.

• Defining the Features we would like to see

  - by Patrick Liekhus

  OK, now that we have a very rough idea of what we are building, let’s get a list of the top features that this application needs to allow us to do.  In this next list we are not prioritizing them yet, just getting on paper the high level backlog of items that this system must do. Add a new task to my work queue Change the status of the task Print a hard copy of the task list by day for my records Log a phone conversation A manager should be able to assign tasks to another user How do we login? Change the Covey roles per user Manage the statuses used Manage the Covey quadrants Can we make this available on the following user interfaces? Windows Desktop Web Browser Sliverlight (WPF) Excel Add-in Outlook Add-in Android Devices iPhone Devices Windows Mobile Devices Blackberry Devices While this looks like a simple spread sheet, it can get pretty complex and busy quickly.  Next time we will work on making this into a Product Backlog and prioritizing the features we would like to see.

• IIS7 + WCF + Silverlight problems

  - by Eanna

  Hey, I've been building a silverlight application and a WCF service for a while now and recently tried to host them in IIS7. I installed IIS7 on Windows Server 2008 R2 and added these two application to my default website. I am having a number of problems so im hoping one of you can help out... 1) The silverlight and WCF service applications do not work with pass-through authentication. I need to "connect as" the administrator server account when setting up the application. I read online that you should only need to use the "connect as" field when you are connecting to another computer. If i dont supply the admin credentials i get this error. Do i have to set up permissions somewhere else? HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Detailed Error Information Module IIS Web Core Notification BeginRequest Handler Not yet determined Error Code 0x80070005 Config Error Cannot read configuration file due to insufficient permissions Config File \?\C:\Users\Administrator\Documents\My Dropbox\Research Masters\Project\WCFService\Website\web.config Requested URL http:://localhost:80/WCFService/Service.svc Physical Path C:\Users\Administrator\Documents\My Dropbox\Research Masters\Project\WCFService\Website\Service.svc Logon Method Not yet determined Logon User Not yet determined Config Source -1: 0: Links and More Information This error occurs when there is a problem reading the configuration file for the Web server or Web application. In some cases, the event logs may contain more information about what caused this error. 2) Visual studio generated 2 webpages to run my silverlight application (.html and .aspx). When I am running the silverlight application (connected as admin) I can navigate to the .html page, no problem. When I try to open the .aspx file i get the following error Server Error in '/Platform' Application. Access is denied. Description: An error occurred while accessing the resources required to serve this request. You might not have permission to view the requested resources. Error message 401.3: You do not have permission to view this directory or page using the credentials you supplied (access denied due to Access Control Lists).

Version Information: Microsoft .NET Framework Version:4.0.30128; ASP.NET Version:4.0.30128.1 3) The WCF service runs fine (again, connected as admin) until i restart the server. When i try to run the WCF service after a reboot, the mysql assembly seems to be missing from the solution. If i just rebuilt the solution and run the service again... it works (until next restart).

  Nowadays we have a number of online file management systems (e.g. DropBox, SkyDrive and Google Drive). People can use them to manage different types of documents. However, one might need a system to manage documents when they do not want to publish the company documents to the cloud. In that case, they need to build an online document management system. This project is intended to meet this purpose. However, it is in the early stage. All the functionalities seem working. A lot of work is needed in the UI. Besides this, code needs refactoring.

• Oracle’s Web Experience Management

  - by Christie Flanagan

  Today’s guest post on Oracle’s Web Experience Management comes from a member of our WebCenter Evangelist team, Noël Jaffré, a Principal Technologist based in France.Oracle’s Web Experience Management (WEM) solution enables organizations to optimize the online channel for driving marketing and customer experience management success. It empowers business users to manage the web presence and create rich and engaging online experiences for customers and prospects. Oracle's WEM platform provides a framework to simplify the integration of Oracle, third-party and custom-built applications. This framework essentially allows the creation and integration of applications using one single business interface called the WEM interface. It includes the following: Single sign-on access control for all integrated applications using the Central Authentication Service (CAS) component. A single centralized administration window for user, role, and native applications management including site management. Community server management, gadget server management as well as management for partner integrated technologies. A Representational State Transfer (REST) API for accessing WebCenter Sites data. REST services are supported on both Oracle WebCenter Sites and Oracle WebCenter Sites Satellite Server to leverage the satellite server cache. All REST requests are cached for web consuming applications as well for the high performance delivery of native applications on the mobile channel. Oracle WebCenter Sites’ Web Experience Management environment enables organizations to deliver a compelling online experience to customers by simplifying the deployment and management of sophisticated and engaging websites. The WebCenter Sites platform automates the entire process of managing web content including: Authoring:  Business users can easily contribute and manage web content in real-time, with intuitive interfaces and drag-and-drop content authoring and layout capabilities designed for the non-technical user. Contextual Content Targeting: Marketers are empowered to create and manage targeted campaigns with relevant recommendations and promotions based on the context of the session of the visitor such as his or her navigation history, user profile, language, location or other information shared during the visitor session. Content Publishing and Deployment: It offers advanced multi-site management capabilities for departmental or regional sites, as well as strong multi-lingual and multi-locale content management. The remote satellite server caching infrastructure provides high-performance, distributed caching, tuned to deliver high-volume, targeted and multi-lingual sites. Analytics and Optimization: Business users and marketers have the ability to measure the effectiveness of their online content and campaigns at a granular level. Editors and marketers can immediately determine whether a given article or promotion is relevant to a particular customer segment. User-generated Content: Marketers can enable blogs, comments, rating and reviews on the website.  All comments and reviews posted to the website can be moderated from the administrator interface either manually or automatically using filters, whitelists, blacklists or community based moderation. Personalized Gadget Dashboards:  Site managers can deploy gadgets, small applications using web content, individually or as part of dashboards containing multiple gadgets.  These gadget dashboards enable site visitors to create their own “MyPage” on a given site where they can select and customize the gadgets that the site administrator has made available.  Any gadget that conforms to the iGoogle/OpenSocial standard can be made available to site visitors, or they can be created within the WEM interface. Oracle's WEM platform also provides a unique environment for the delivery of a rich, multichannel online experience for site visitors through its advanced management modules for mobile. With Oracle’s WEM solution, it’s easy to control branding and deliver a consistent message while repurposing web content for publication to mobile devices, kiosks and much more. This distinctive approach provides: HTML5 Delivery: HTML5 delivery which includes native support for adaptive design that responds to the user’s computer screen resolution and orientation. The approach is less driven by the particular hardware and more driven by the user’s interactions with the device. In other words, this approach takes both the screen interactions (either cursor or touch) and screen sizes and orientation into consideration. A Unique Native Mobile Extension Environment for Contributors: From the WEM interface, a contributor can directly manage their mobile channel, using the tooling already in place for driving the traditional web presence. This includes the mobile presentation, as well as mobile insite editing, drag and drop page layout, and in-context recommendations and personalization. Optimized REST APIs for High Performance Content Delivery on Native Mobile Device Applications: WebCenter Sites’ REST API uses the underlying HTTP methods (GET, POST, PUT, DELETE) to interact with resources. Resources support two types of input and output formats -- XML and JSON. REST calls are customizable to optimize the interactions between the content repositories and the client applications. Caching is essential to decrease network loads and improve overall reliability and usability of the applications and user interactions. REST results are cached through the highly efficient Oracle WebCenter Sites caching architecture.

• ASP.net roles and Projects

  - by Zyphrax

  EDIT - Rewrote my original question to give a bit more information Background info At my work I'm working on a ASP.Net web application for our customers. In our implementation we use technologies like Forms authentication with MembershipProviders and RoleProviders. All went well until I ran into some difficulties with configuring the roles, because the roles aren't system-wide, but related to the customer accounts and projects. I can't name our exact setup/formula, because I think our company wouldn't approve that... What's a customer / project? Our company provides management information for our customers on a yearly (or other interval) basis. In our systems a customer/contract consists of: one Account: information about the Company per Account, one or more Products: the bundle of management information we'll provide per Product, one or more Measurements: a period of time, in which we gather and report the data Extranet site setup Eventually we want all customers to be able to access their management information with our online system. The extranet consists of two sites: Company site: provides an overview of Account information and the Products Measurement site: after selecting a Measurement, detailed information on that period of time The measurement site is the most interesting part of the extranet. We will create submodules for new overviews, reports, managing and maintaining resources that are important for the research. Our Visual Studio solution consists of a number of projects. One web application named Portal for the basis. The sites and modules are virtual directories within that application (makes it easier to share MasterPages among things). What kind of roles? The following users (read: roles) will be using the system: Admins: development users :) (not customer related, full access) Employees: employees of our company (not customer related, full access) Customer SuperUser: top level managers (full access to their account/measurement) Customer ContactPerson: primary contact (full access to their measurement(s)) Customer Manager: a department manager (limited access, specific data of a measurement) What about ASP.Net users? The system will have many ASP.Net users, let's focus on the customer users: Users are not shared between Accounts SuperUser X automatically has access to all (and new) measurements User Y could be Primary contact for Measurement 1, but have no role for Measurement 2 User Y could be Primary contact for Measurement 1, but have a Manager role for Measurement 2 The department managers are many individual users (per Measurement), if Manager Z had a login for Measurement 1, we would like to use that login again if he participates in Measurement 2. URL structure These are typical urls in our application: http://host/login - the login screen http://host/project - the account/product overview screen (measurement selection) http://host/project/1000 - measurement (id:1000) details http://host/project/1000/planning - planning overview (for primary contact/superuser) http://host/project/1000/reports - report downloads (manager department X can only access report X) We will also create a document url, where you can request a specific document by it's GUID. The system will have to check if the user has rights to the document. The document is related to a Measurement, the User or specific roles have specific rights to the document. What's the problem? (finally ;)) Roles aren't enough to determine what a user is allowed to see/access/download a specific item. It's not enough to say that a certain navigation item is accessible to Managers. When the user requests Measurement 1000, we have to check that the user not only has a Manager role, but a Manager role for Measurement 1000. Summarized: How can we limit users to their accounts/measurements? (remember superusers see all measurements, some managers only specific measurements) How can we apply roles at a product/measurement level? (user X could be primarycontact for measurement 1, but just a manager for measurement 2) How can we limit manager access to the reports screen and only to their department's reports? All with the magic of asp.net classes, perhaps with a custom roleprovider implementation.

• How to change disclosure style when user enters in edit mode of a UITableView?

  - by R31n4ld0

  Hello, guys. I have a UITableView that in 'normal' mode, show a UITableViewCellAccessoryDisclosureIndicator meaning if the user taps the row, another list is showed, like HIG says: "Disclosure indicator. When this element is present, users know they can tap anywhere in the row to see the next level in the hierarchy or the choices associated with the list item. Use a disclosure indicator in a row when selecting the row results in the display of another list. Don’t use a disclosure indicator to reveal detailed information about the list item; instead, use a detail disclosure button for this purpose." When the user tap the edit button in the top bar of the UITableView, I think I have to change the disclosure because if the user tap it, a view for changing the information of the current row is showed (see the bold line above), again, like HIG says: "Detail disclosure button. Users tap this element to see detailed information about the list item. (Note that you can use this element in views other than table views, to reveal additional details about something; see “Detail Disclosure Buttons” for more information.) In a table view, use a detail disclosure button in a row to display details about the list item. Note that the detail disclosure button, unlike the disclosure indicator, can perform an action that is separate from the selection of the row. For example, in Phone Favorites, tapping the row initiates a call to the contact; tapping the detail disclosure button in the row reveals more information about the contact." Have I miss understood the HIG, or I really do have to change the disclosure style in edit mode of UITableView? If yes, how I can intercept the edit mode when the user taps the Edit button? Thanks in advance.
