• Is HR/Recruitment Really Ready For Innovative Candidates

  - by david.talamelli

  Before I begin this blog post, I want to acknowledge that there are some great HR/Recruitment people out there who are innovative and are leading the way in using new means to successfully attract and connect with talented people. For those of you who fit in this category, please keep thinking outside the square - just because what you do may not be the norm doesn't mean it is bad. Ok, with that acknowledgment out of the way - Earlier this morning (I started this post Friday morning) I came across this online profile via a tweet from Philip Tusing I love the information that Jason has put on his web-pages. From his work Jason clearly demonstrates not only his skills/experience but also I love how he relates his experience and shows how it will help an employer and what the value add of having him on your team is. Looking at Jason's profile makes me think though, is HR/Recruitment in general terms ready to deal with innovative candidates. Sure most Recruiters are online in some form or another, but how many actually have a process that is flexible enough to deal with someone who may not fit into your processes. Is your company's recruitment practice proactive enough to find Jason's web-pages? I am not sure what he is doing in terms of a job search, but if he is not mailing a resume or replying to ads on a Job Board - hopefully Jason comes up on some of the candidate searching you are doing. Once you find this information, would the information Jason provides fit nicely into your Applicant Tracking System or your Database? If not, how much of the intangible information are you losing and potentially not passing on to a Hiring Manager. I think what has worked in the past will not necessarily work in the future. Candidates want to work somewhere they will be challenged and learn and grow. If your HR/Recruitment team displays processes that take don't necessarily convey this message, this potentially could turn people away who were once interested in your company. For example (and I have to admit I still do some of these things myself), once calling up and having a talk to a candidate a company may say: 1) HR Question: Send me in a copy of your resume - Candidate Reply - you actually already have my resume, the web-page is http:// 2) HR Question:Come in for a chat so we can get to know you - Candidate Reply - if this is the basis of a meeting, you already know me and my thoughts by looking at my online links (blog, portfolio, homepage, etc...) These questions if not handled properly could potentially turn a candidate from being interested in your company to not being interested in your company. It potentially could demonstrate that your company is not social media savvy or maybe give the impression of not really being all that innovative. A candidate may think, if this company isn't able to take information I have provided in the public forum and use it, is it really a company I want to work for? I think when liaising with candidates a company should utilise the information the person has provided in the public domain. A candidate may inadvertantly give you answers to many of the questions you are seeking on their online presence and save everyone time instead of having to fill out forms or paperwork. If you build this into your conversations with your candidates it becomes a much more individualised service you are providing and really demonstrates to a candidate you are thinking of them as an individual. Yes I know we need to have processes in place and I am not saying don't work to those processes, but don't let process take away a candidates individuality. Don't let your process inadvertently scare away the top candidates that you may want in your company. This article was originally posted on David Talamelli's Blog - David's Journal on Tap

• Using NServiceBus behind a custom web service

  - by Michael Stephenson

  In this post I'd like to talk about an architecture scenario we had recently and how we were able to utilise NServiceBus to help us address this problem. Scenario Cognos is a reporting system used by one of my clients. A while back we developed a web service façade to allow line of business applications to be able to access reports from Cognos to support their various functions. The service was intended to provide access to reports which were quick running reports or pre-generated reports which could be accessed real-time on demand. One of the key aims of the web service was to provide a simple generic interface to allow applications to get any report without needing to worry about the complex .net SDK for Cognos. The web service also supported multi-hop kerberos delegation so that report data could be accesses under the context of the end user. This service was working well for a period of time. The Problem The problem we encountered was that reports were now also required to be available to batch processes. The original design was optimised for low latency so users would enjoy a positive experience, however when the batch processes started to request 250+ concurrent reports over an extended period of time you can begin to imagine the sorts of problems that come into play. The key problems this new scenario caused are: Users may be affected and the latency of on demand reports was significantly slower The Cognos infrastructure was not scaled sufficiently to be able to cope with these long peaks of load From a cost perspective it just isn't feasible to scale the Cognos infrastructure to be able to handle the load when it is only for a couple of hour window each night. We really needed to introduce a second pattern for accessing this service which would support high through-put scenarios. We also had little control over the batch process in terms of being able to throttle its load. We could however make some changes to the way it accessed the reports. The Approach My idea was to introduce a throttling mechanism between the Web Service Façade and Cognos. This would allow the batch processes to push reports requests hard at the web service which we were confident the web service can handle. The web service would then queue these requests and process them behind the scenes and make a call back to the batch application to provide the report once it had been accessed. In terms of technology we had some limitations because we were not able to use WCF or IIS7 where the MSMQ-Activated WCF services could have helped, but we did have MSMQ as an option and I thought NServiceBus could do just the job to help us here. The flow of how this would work was as follows: The batch applications would send a request for a report to the web service The web service uses NServiceBus to send the message to a Queue The NServiceBus Generic Host is running as a windows service with a message handler which subscribes to these messages The message handler gets the message, accesses the report from Cognos The message handler calls back to the original batch application, this is decoupled because the calling application provides a call back url The report gets into the batch application and is processed as normal This approach looks something like the below diagram: The key points are an application wanting to take advantage of the batch driven reports needs to do the following: Implement our call back contract Make a call to the service providing a call back url Provide a correlation ID so it knows how to tie each response back to its request What does NServiceBus offer in this solution So this scenario is not the typical messaging service bus type of solution people implement with NServiceBus, but it did offer the following: Simplified interaction with MSMQ Offered the ability to configure the number of processes working through the queue so we could find a balance between load on Cognos versus the applications end to end processing time NServiceBus offers retries and a way to manage failed messages NServiceBus offers a high availability setup The simple thing is that NServiceBus gave us the platform to build the solution on. We just implemented a message handler which functionally processed a message and we could rely on NServiceBus to do all of the hard work around managing the queues and all of the lower level things that would have took ages to write to any kind of robust level. Conclusion With this approach we were able to deal with a fairly significant performance issue with out too much rework. Hopefully this write up gives people some insight into ideas on how to leverage the excellent NServiceBus framework to help solve integration and high through-put scenarios.

• The Next Wave of PeopleSoft Capabilities for the Staffing Industry Is Here

  - by Mark Rosenberg

  With the release of PeopleSoft Financials and Supply Chain Management 9.1 Feature Pack 2 in January this year, we introduced substantial new capabilities for our Staffing Industry customers. Through a co-development project with Infosys Limited, we have enriched Oracle's PeopleSoft Staffing Solution with new tools aimed at accelerating and improving the quality of job order fulfillment, increasing branch recruiter productivity, and driving profitable growth. Staffing industry firms succeed based on their ability to rapidly, cost-effectively, and continually fill their pipelines with new clients and job orders, recruit the best talent, and match orders with talent. Pressure to execute in each of these functional areas is even more acute on staffing firms as contingent labor becomes a more substantial and permanent part of the workforce mix. In an industry that creates value through speedy execution, there is little room for manual, inefficient processes and brittle, custom integrations, which throttle profitability and growth. The latest wave of investment in the PeopleSoft Staffing Solution focuses on generating efficiency and flexibility for our customers. Simplicity To operate profitably and continue growing, a Staffing enterprise needs its client management, recruiting, order fulfillment, and other processes to function in harmony. Most importantly, they need to be simple for recruiters, branch managers, and applicants to access and understand. The latest PeopleSoft Staffing Solution set of enhancements includes numerous automated defaulting mechanisms and information-rich dashboard pagelets that even a new employee can learn quickly. Pending Applicant, Agenda management, Search, and other pagelets are just a few of the newest, easy-to-use tools that not only aggregate and summarize information, but also provide instant access to applicants, tasks, and key reports for branch staff. Productivity The leading firms in the Staffing industry are those that can more efficiently orchestrate large numbers of candidates, clients, and orders than their competitors can. PeopleSoft Financials and Supply Chain Management 9.1 Feature Pack 2 delivers productivity boosters that Staffing firms can leverage to streamline tasks and processes for competitive advantage. For example, we enhanced the Recruiting Funnel, which manages the candidate on-boarding process, with a highly interactive user interface. It integrates disparate Staffing business processes and exploits new PeopleTools technologies to offer a superior on-boarding user experience. Automated creation of agenda items and assignment tasks for each candidate minimizes setup and organizes assignment steps for the on-boarding process. Mass updates of tasks and instant access to the candidate overview page (which we also expanded), candidate event status, event counts, and other key data enable recruiters to better serve clients and candidates. Lower TCO Constructing and maintaining an efficient yet flexible labor supply chain can be complicated, let alone expensive. Traditionally, Staffing firms have been challenged in controlling their technology cost of ownership because connecting candidate and client-facing tools involved building and integrating custom applications and technologies and managing staff turnover, placing heavy demands on IT and support staff. With PeopleSoft Financials and Supply Chain Management 9.1 Feature Pack 2, there are two major enhancements that aggressively tackle these challenges. First, we added another integration framework to enable cost-effective linking of the Staffing firm’s PeopleSoft applications and its job board distributors. (The first PeopleSoft 9.1 Feature Pack released in March 2011 delivered an integration framework to connect to resume parsing providers.) Second, we introduced the teaming concept to enable work to be partitioned to groups, as well as individuals. These two capabilities, combined with a host of others, position Staffing firms to configure and grow their businesses without growing their IT and overhead expenditures. For our Staffing Industry customers, PeopleSoft Financials and Supply Chain Management 9.1 Feature Pack 2 is loaded with high-value tools aimed at enabling and sustaining a flexible labor supply chain.

• Three Key Tenets of Optimal Social Collaboration

  - by kellsey.ruppel

  Today's blog post comes to us from John Bruswick! This post is an abridged version of John’s white paper in which he discusses three principals to optimize social collaboration within an enterprise.   By [email protected], Oracle Principal Sales Consultant Effective social collaboration is actionable, deeply contextual and inherently derives its value from business entities outside of itself. How does an organization begin the journey from traditional, siloed collaboration to natural, business entity based social collaboration? Successful enablement of enterprise social collaboration requires that organizations embrace the following tenets and understand that traditional collaborative functionality has inherent limits - it is innovation and integration in accordance with the following tenets that will provide net-new efficiency benefits. Key Tenets of Optimal Social Collaboration Leverage a Ubiquitous Social Fabric - Collaborative activities should be supported through a ubiquitous social fabric, providing a personalized experience, broadcasting key business events and connecting people and business processes.  This supports education of participants working in and around a specific business entity that will benefit from an implicit capture of tacit knowledge and provide continuity between participants.  In the absence of this ubiquitous platform activities can still occur but are essentially siloed causing frequent duplication of effort across similar tasks, with critical tacit knowledge eluding capture. Supply Continuous Context to Support Decision Making and Problem Solving - People generally engage in collaborative behavior to obtain a decision or the resolution for a specific issue.  The time to achieve resolution is referred to as "Solve Time".  Users have traditionally been forced to switch or "alt-tab" between business systems and synthesize their own context across disparate systems and processes.  The constant loss of context forces end users to exert a large amount of effort that could be spent on higher value problem solving. Extend the Collaborative Lifecycle into Back Office - Beyond the solve time from decision making efforts, additional time is expended formalizing the resolution that was generated from collaboration in a system of record.  Extending collaboration to result in the capture of an explicit decision maximizes efficiencies, creating a closed circuit for a particular thread.  This type of structured action may exist today within your organization's customer support system around opening, solving and closing support issues, but generally does not extend to Sales focused collaborative activities. Excelling in the Unstructured Future We will always have to deal with unstructured collaborative processes within our organizations.  Regardless of the participants and nature of the collaborate process, two things are certain – the origination and end points are generally known and relate to a business entity, perhaps a customer, opportunity, order, shipping location, product or otherwise. Imagine the benefits if an organization's key business systems supported a social fabric, provided continuous context and extended the lifecycle around the collaborative decision making to include output into back office systems of record.   The technical hurdle to embracing optimal social collaboration would fall away, leaving the company with an opportunity to focus on and refine how processes were approached.  Time and resources previously required could then be reallocated to focusing on innovation to support competitive differentiation unique to your business. How can you achieve optimal social collaboration? Oracle Social Network enables business users to collaborate with each other using a broad range of collaboration styles and integrates data from a variety of sources and business applications -- allowing you to achieve optimal social collaboration. Looking to learn more? Read John's white paper, where he discusses in further detail the three principals to optimize social collaboration within an enterprise.

• Where's My Windows Azure Subscriptions

  - by Shaun

  Originally posted on: http://geekswithblogs.net/shaunxu/archive/2013/11/03/wheres-my-windows-azure-subscriptions.aspxYesterday when I opened Windows Azure manage portal I found some resources were missed. I checked the website for those missed cloud service and they are still live. Then I checked my billing history but didn't found any problem. When I back to the portal I found that all of those resource are under my MSDN subscription. So I remembered that if this is related with the recently Windows Azure platform update.   This feature named "Enterprise Management", which provides the ability to manage your organization in a directory which is hosted entirely in the cloud, or alternatively kept in sync with an on-premises Windows Server Active Directory solution. By default, all existing windows azure account would have a default Windows Azure Active Directory (a.k.a. WAAD) associated. In the address bar I can find the default login WAAD of my account, which is "microsoft.onmicrosoft.com". To change the WAAD we can click "subscriptions" on top of the manage portal, select the active directory from the list of "filter by directory" and select the subscription we want to see, then press "apply". As you can see, the subscription under my MSDN was located in a WAAD named "beijingtelecom.onmicrosoft.com". This is because when Microsoft applied this feature, they will check if you have an existing WAAD in your subscription. If not, it will create a new one, otherwise it will use your WAAD and move your subscription into this directory. Since I created a WAAD for test several months ago, this subscription was moved to this directory.   To change the subscription's directory is simple. First we need to create a new WAAD with the name we preferred. As below I created a new directory named "shaunxu". Then select "settings" from the left navigation bar, select the subscription we wanted to change and click "edit directory". You don't have the permission to edit/change directory unless your Microsoft Account is the service administrator of this subscription. Then in the popup window, select the WAAD you want to change and press "next". All done. You need to log off and log in the portal then your subscription will be in the directory you wanted. And after these steps I can view my resources in this subscription.   Summary In this post I described how to change subscriptions into a new directory. With this new feature we can manage our Windows Azure subscription more flexible. But there are something we need keep in mind. 1. Only the service administrator could be able to move subscription. 2. Currently there's no way for us to see our Windows Azure services in more than one directory at the same time. Like me, I can see my services under "shaunxu.onmicrosoft.com" and I must change the filter directory from the "subscriptions" menu to see other services under "microsoft.onmicrosoft.com". 3. Currently we cannot delete an existing WAAD.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind. Copyright © Shaun Ziyan Xu.

• Orchestrating the Virtual Enterprise, Part II

  - by Kathryn Perry

  A guest post by Jon Chorley, Oracle's CSO & Vice President, SCM Product Strategy Almost everyone has ordered from Amazon.com at one time or another. Our orders are as likely to be fulfilled by third parties as they are by Amazon itself. To deliver the order promptly and efficiently, Amazon has to send it to the right fulfillment location and know the availability in that location. It needs to be able to track status of the fulfillment and deal with exceptions. As a virtual enterprise, Amazon's operations, using thousands of trading partners, requires a very different approach to fulfillment than the traditional 'take an order and ship it from your own warehouse' model. Amazon had no choice but to develop a complex, expensive and custom solution to tackle this problem as there used to be no product solution available. Now, other companies who want to follow similar models have a better off-the-shelf choice -- Oracle Distributed Order Orchestration (DOO).  Consider how another of our customers is using our distributed orchestration solution. This major airplane manufacturer has a highly complex business and interacts regularly with the U.S. Government and major airlines. It sits in the middle of an intricate supply chain and needed to improve visibility across its many different entities. Oracle Fusion DOO gives the company an orchestration mechanism so it could improve quality, speed, flexibility, and consistency without requiring an organ transplant of these highly complex legacy systems. Many retailers face the challenge of dealing with brick and mortar, Web, and reseller channels. They all need to be knitted together into a virtual enterprise experience that is consistent for their customers. When a large U.K. grocer with a strong brick and mortar retail operation added an online business, they turned to Oracle Fusion DOO to bring these entities together. Disturbing the Peace with Acquisitions Quite often a company's ERP system is disrupted when it acquires a new company. An acquisition can inject a new set of processes and systems -- or even introduce an entirely new business like Sun's hardware did at Oracle. This challenge has been a driver for some of our DOO customers. A large power management company is using Oracle Fusion DOO to provide the flexibility to rapidly integrate additional products and services into its central fulfillment operation. The Flip Side of Fulfillment Meanwhile, we haven't ignored similar challenges on the supply side of the equation. Specifically, how to manage complex supply in a flexible way when there are multiple trading parties involved? How to manage the supply to suppliers? How to manage critical components that need to merge in a tier two or tier three supply chain? By investing in supply orchestration solutions for the virtual enterprise, we plan to give users better visibility into their network of suppliers to help them drive down costs. We also think this technology and full orchestration process can be applied to the financial side of organizations. An example is transactions that flow through complex internal structures to minimize tax exposure. We can help companies manage those transactions effectively by thinking about the internal organization as a virtual enterprise and bringing the same solution set to this internal challenge.  The Clear Front Runner No other company is investing in solving the virtual enterprise supply chain issues like Oracle is. Oracle is in a unique position to become the gold standard in this market space. We have the infrastructure of Oracle technology. We already have an Oracle Fusion DOO application which embraces the best of what's required in this area. And we're absolutely committed to extending our Fusion solution to other use cases and delivering even more business value.

• Have Your Cake and Eat it Too: Industry Best Practices + Flexibility

  - by Oracle Accelerate for Midsize Companies

  By Richard Garraputa, VP of Sales & Marketing, brij Richard joined brij in 1996 after graduating from the University of North Carolina at Greensboro with degrees in Information Systems and Accounting. He directs brij’s overall strategies of both the business development and marketing departments. Companies looking for new ERP systems spend so much time comparing features and functions of software products but too often short change the value of their own processes.  Company managers I meet often claim that they are implementing a new ERP system so they can perform better and faster.  When asked how, the answer is often “by implementing best practices”.  But the term ‘best practices’ is frequently used to mean ‘doing things the way everyone else does them’ rather than a starting point or benchmark to build upon by adding your own value. Of course, implementing standardized processes across an enterprise is an important step in improving operational efficiencies.  But not all companies are alike.  Do you ever tell your customers “We are just like our competition and have no competitive differentiation”?  Probably not.  So why should the implementation of your business processes be just like your competitor’s?  Even within the same industry, companies differentiate themselves by leveraging their unique expertise and approach to business.  These unique aspects—the competitive differentiators that companies use to thrive in a crowded marketplace—can and should be supported by the implementation of business systems like ERP. Modern ERP systems like Oracle’s JD Edwards EnterpriseOne have a broad and deep functional footprint designed to integrate a company’s core operations.  But how can a company take advantage of this footprint without blowing up their implementation budget?  Some ERP vendors claim to solve this challenge by stating that their systems come pre-configured with ‘best practices’.  Too often what they are really saying is that you will have to abandon your key operational differentiators to fit a vendor’s template for your business—or extend your implementation and postpone the realization of any benefits. Thankfully for midsize companies, there is an alternative to the undesirable options of extended implementation projects or abandoning their competitive differentiators.  Oracle Accelerate Solutions speed the time it takes to implement JD Edwards EnterpriseOne solution based on your unique business characteristics, getting your new ERP system up and running faster without forcing your business to fit a cookie-cutter solution. We’ve been a JD Edwards implementation partner since 1986 and we now leverage Oracle Business Accelerators—cloud based rapid implementation tools built and maintained by Oracle. Oracle Business Accelerators deliver the benefits of embedded industry best practices without forcing every customer in to one set of processes like many template or “clone and go” approaches do. You retain the ability to reconfigure your applications—without customization—as your business changes. Wielded by Oracle partners with industry-specific domain expertise, Oracle Accelerate Solution implementations powered by Oracle Business Accelerators help automate the application configuration to fit your business better, faster. For example, on a recent project at a manufacturing company, the project manager told me that Oracle Business Accelerators helped get them to Conference Room Pilot 20% faster than with a traditional approach. Time savings equal cost savings. And if ‘better and faster’ is your goal for your business performance, shouldn’t it be the goal for your ERP implementation as well? Established in 1986, brij has been dedicated solely to helping its customers implement Oracle’s JD Edwards solutions and to maximize the value of those customers’ IT investments. They are a Gold level member in Oracle PartnerNetwork and an Oracle Accelerate Solution provider.

• MPI Cluster Debugger launch integration in VS2010

  Let's assume that you have all the HPC bits installed and that you have existing MPI code (or you created a "Hello World" project using the MPI project template). Of course, you create a single MPI application and at runtime it will correspond to multiple processes (of the same app) launched on multiple nodes (i.e. machines) on the cluster. So how do you debug such a situation by simply hitting the familiar "F5" keystroke (i.e. Debug - Start Debugging)?WATCH IT INSTEAD OF READING ABOUT ITIf you can't bear to read through all the details below, just watch this 19-minute screencast explaining this VS2010 feature. Alternatively, or even additionally, keep on reading.REQUIREMENTWhen you debug an MPI application, you would want the copying of resources from your client machine (where Visual Studio is installed) to each compute node (where Windows HPC Server is installed) to take place automatically for you. 'Resources' in the previous sentence includes your application binary, plus any binary or data dependencies it may have, plus PDBs if needed, plus the debug CRT of the correct bitness, plus msvsmon for remote debugging to work. You would also want, after copying is complete, to have your app and msvsmon launched and attached so that you can hit breakpoints back in Visual Studio on your client machine. All these thing that you would want are delivered in VS2010.STEPS TO F51. In your MPI project where you have placed a breakpoint go to Project Properties - Configuration Properties - Debugging.

• #OOW 2012: Big Data and The Social Revolution

  - by Eric Bezille

  As what was saying Cognizant CSO Malcolm Frank about the "Futur of Work", and how the Business should prepare in the face of the new generation  not only of devices and "internet of things" but also due to their users ("The Millennials"), moving from "consumers" to "prosumers" :  we are at a turning point today which is bringing us to the next IT Architecture Wave. So this is no more just about putting Big Data, Social Networks and Customer Experience (CxM) on top of old existing processes, it is about embracing the next curve, by identifying what processes need to be improve, but also and more importantly what processes are obsolete and need to be get ride of, and new processes put in place. It is about managing both the hierarchical and structured Enterprise and its social connections and influencers inside and outside of the Enterprise. And this does apply everywhere, up to the Utilities and Smart Grids, where it is no more just about delivering (faster) the same old 300 reports that have grown over time with those new technologies but to understand what need to be looked at, in real-time, down to an hand full relevant reports with the KPI relevant to the business. It is about how IT can anticipate the next wave, and is able to answers Business questions, and give those capabilities in real-time right at the hand of the decision makers... This is the turning curve, where IT is really moving from the past decade "Cost Center" to "Value for the Business", as Corporate Stakeholders will be able to touch the value directly at the tip of their fingers. It is all about making Data Driven Strategic decisions, encompassed and enriched by ALL the Data, and connected to customers/prosumers influencers. This brings to stakeholders the ability to make informed decisions on question like : “What would be the best Olympic Gold winner to represent my automotive brand ?”... in a few clicks and in real-time, based on social media analysis (twitter, Facebook, Google+...) and connections link to my Enterprise data. A true example demonstrated by Larry Ellison in real-time during his yesterday’s key notes, where “Hardware and Software Engineered to Work Together” is not only about extreme performances but also solutions that Business can touch thanks to well integrated Customer eXperience Management and Social Networking : bringing the capabilities to IT to move to the IT Architecture Next wave. An example, illustrated also todays in 2 others sessions, that I had the opportunity to attend. The first session bringing the “Internet of Things” in Oil&Gaz into actionable decisions thanks to Complex Event Processing capturing sensors data with the ready to run IT infrastructure leveraging Exalogic for the CEP side, Exadata for the enrich datasets and Exalytics to provide the informed decision interface up to end-user. The second session showing Real Time Decision engine in action for ACCOR hotels, with Eric Wyttynck, VP eCommerce, and his Technical Director Pascal Massenet. I have to close my post here, as I have to go to run our practical hands-on lab, cooked with Olivier Canonge, Christophe Pauliat and Simon Coter, illustrating in practice the Oracle Infrastructure Private Cloud recently announced last Sunday by Larry, and developed through many examples this morning by John Folwer. John also announced today Solaris 11.1 with a range of network innovation and virtualization at the OS level, as well as many optimizations for applications, like for Oracle RAC, with the introduction of the lock manager inside Solaris Kernel. Last but not least, he introduced Xsigo Datacenter Fabric for highly simplified networks and storage virtualization for your Cloud Infrastructure. Hoping you will get ready to jump on the next wave, we are here to help...

• Indexed view deadlocking

  - by Dave Ballantyne

  Deadlocks can be a really tricky thing to track down the root cause of.  There are lots of articles on the subject of tracking down deadlocks, but seldom do I find that in a production system that the cause is as straightforward.  That being said,  deadlocks are always caused by process A needs a resource that process B has locked and process B has a resource that process A needs.  There may be a longer chain of processes involved, but that is the basic premise. Here is one such (much simplified) scenario that was at first non-obvious to its cause: The system has two tables,  Products and Stock.  The Products table holds the description and prices of a product whilst Stock records the current stock level. USE tempdb GO CREATE TABLE Product ( ProductID INTEGER IDENTITY PRIMARY KEY, ProductName VARCHAR(255) NOT NULL, Price MONEY NOT NULL ) GO CREATE TABLE Stock ( ProductId INTEGER PRIMARY KEY, StockLevel INTEGER NOT NULL ) GO INSERT INTO Product SELECT TOP(1000) CAST(NEWID() AS VARCHAR(255)), ABS(CAST(CAST(NEWID() AS VARBINARY(255)) AS INTEGER))%100 FROM sys.columns a CROSS JOIN sys.columns b GO INSERT INTO Stock SELECT ProductID,ABS(CAST(CAST(NEWID() AS VARBINARY(255)) AS INTEGER))%100 FROM Product There is a single stored procedure of GetStock: Create Procedure GetStock as SELECT Product.ProductID,Product.ProductName FROM dbo.Product join dbo.Stock on Stock.ProductId = Product.ProductID where Stock.StockLevel <> 0 Analysis of the system showed that this procedure was causing a performance overhead and as reads of this data was many times more than writes,  an indexed view was created to lower the overhead. CREATE VIEW vwActiveStock With schemabinding AS SELECT Product.ProductID,Product.ProductName FROM dbo.Product join dbo.Stock on Stock.ProductId = Product.ProductID where Stock.StockLevel <> 0 go CREATE UNIQUE CLUSTERED INDEX PKvwActiveStock on vwActiveStock(ProductID) This worked perfectly, performance was improved, the team name was cheered to the rafters and beers all round.  Then, after a while, something else happened… The system updating the data changed,  The update pattern of both the Stock update and the Product update used to be: BEGIN TRAN UPDATE... COMMIT BEGIN TRAN UPDATE... COMMIT BEGIN TRAN UPDATE... COMMIT It changed to: BEGIN TRAN UPDATE... UPDATE... UPDATE... COMMIT Nothing that would raise an eyebrow in even the closest of code reviews.  But after this change we saw deadlocks occuring. You can reproduce this by opening two sessions. In session 1 begin transaction Update Product set ProductName ='Test' where ProductID = 998 Then in session 2 begin transaction Update Stock set Stocklevel = 5 where ProductID = 999 Update Stock set Stocklevel = 5 where ProductID = 998 Hop back to session 1 and.. Update Product set ProductName ='Test' where ProductID = 999 Looking at the deadlock graphs we could see the contention was between two processes, one updating stock and the other updating product, but we knew that all the processes do to the tables is update them.  Period.  There are separate processes that handle the update of stock and product and never the twain shall meet, no reason why one should be requiring data from the other.  Then it struck us,  AH the indexed view. Naturally, when you make an update to any table involved in a indexed view, the view has to be updated.  When this happens, the data in all the tables have to be read, so that explains our deadlocks.  The data from stock is read when you update product and vice-versa. The fix, once you understand the problem fully, is pretty simple, the apps did not guarantee the order in which data was updated.  Luckily it was a relatively simple fix to order the updates and deadlocks went away.  Note, that there is still a *slight* risk of a deadlock occurring, if both a stock update and product update occur at *exactly* the same time.

• MPI Cluster Debugger launch integration in VS2010

  Let's assume that you have all the HPC bits installed and that you have existing MPI code (or you created a "Hello World" project using the MPI project template). Of course, you create a single MPI application and at runtime it will correspond to multiple processes (of the same app) launched on multiple nodes (i.e. machines) on the cluster. So how do you debug such a situation by simply hitting the familiar "F5" keystroke (i.e. Debug - Start Debugging)?WATCH IT INSTEAD OF READING ABOUT ITIf you can't bear to read through all the details below, just watch this 19-minute screencast explaining this VS2010 feature. Alternatively, or even additionally, keep on reading.REQUIREMENTWhen you debug an MPI application, you would want the copying of resources from your client machine (where Visual Studio is installed) to each compute node (where Windows HPC Server is installed) to take place automatically for you. 'Resources' in the previous sentence includes your application binary, plus any binary or data dependencies it may have, plus PDBs if needed, plus the debug CRT of the correct bitness, plus msvsmon for remote debugging to work. You would also want, after copying is complete, to have your app and msvsmon launched and attached so that you can hit breakpoints back in Visual Studio on your client machine. All these thing that you would want are delivered in VS2010.STEPS TO F51. In your MPI project where you have placed a breakpoint go to Project Properties - Configuration Properties - Debugging. Ensure the "Debugger to launch" combo box value is set to MPI Cluster Debugger.2. There are a whole bunch of properties here and typically you can ignore all of them except one: Run Environment.

• I am starting to think that Prevx.com isnt a legit site...but heres my long-winded question

  - by cop1152

  I apologize in advance for the long-winded post. I posted it all because I believe its informative and may be useful. Also, I posted my question at the end. Moments ago I was RDC to a file server in my home (from inside my home). I had opened Firefox and Googled for a manufacturers website. Immediately after clicking the link, Firefox abruptly closed. This seemed odd to me to so I checked the running processes and discovered d.exe, e.exe, and f.exe running. I Googled these processes on a different machine and found them belonging to a key-logger/screen-capturer/trojan called defender.exe, which according to the Prevx lives in c:\documents and settings\user\local settings\temp. (Prevx link http://www.prevx.com/filenames/147352809685142526-X1/DEFENDER32.EXE.html) Simultaneously, an obviously-spoofed Windows Firewall popup appeared on the server asking me to click ‘yes’ to update Windows Firewall. At this time I ended all rogue processes, emptied the temp folder, removed defender.exe from startup, and checked my registry and a few other locations. Before deleting Defender.exe I noted that it was created moments ago, just before Firefox crashed. I believe that I was ‘almost’ infected with this malware. I believe that it needed me to click the phony popup in order to complete infection because it wasn’t allowed to execute processes from the temp folder. After cleaning the machine, I restarted it and have been monitoring it for over an hour. I am debating on whether or not to restore the Windows partition (a separate physical drive from the data) or to just watch it for awhle. I should mention that, because of the specs on this machine, I do not run antivirus software, but I know it well and inspect it regularly. It is a very old Compaq with a 400mhz processer and 512mb of ram. I have a static IP and the server is in the DMZ running an FTP client and some HTTP server software. All files transferred to and stored on this machine are scanned for malware before transferring. Usually the machine only runs 19 processes and performs pretty well for its intended purpose. I posted the story so that you could be aware of a possible new piece of malware and how it acts, but I also have a question or two. First, over the last few months I have noticed that PREVX is listed at the top of most of my Google searches when researching malware, especially for new or obscure malware…and they always want you to purchase something. I don’t think they are one of the top AV companies, so it seems odd that they are always the top Google result. Does anyone have any experience with any of their products? Also, what sites do you rely on for malware researching? Recently, I have found it difficult to find good info because of HijackThis-logs and other deadend info cluttering up my searches. And lastly, besides antivirus, third-party firewall, etc, what settings would you use to lock down a machine to make it more secure in instances where a stubborn admin like myself refuses to run AV? Thanks.

• Force x86 CLR on 'Any CPU' .NET assembly

  - by jeffora

  In .NET, the 'Platform Target: Any CPU' compiler option allows a .NET assembly to run as 64bit on a x64 machine, and 32bit on an x86 machine. It is also possible to force an assembly to run as x86 on an x64 machine using the 'Platform Target: x86' compiler option. Is it possible to run an assembly with the 'Any CPU' flag, but determine whether it should be run in the x86 or x64 CLR? Normally this decision is made by the CLR/OS Loader (as is my understanding) based on the bitness of the underlying system. I am trying to write a C# .NET application that can interact with (read: inject code into) other running processes. x64 processes can only inject into other x64 processes, and the same with x86. Ideally, I would like to take advantage of JIT compilation and the Any CPU option to allow a single application to be used to inject into either x64 or x86 processes (on an x64 machine). The idea is that the application would be compiled as Any CPU. On an x64 machine it would run as x64. If the target process is x86, it should relaunch itself, forcing the CLR to run it as x86. Is this possible?

• Fork in Perl not working inside a while loop reading from file

  - by Sag

  Hi, I'm running a while loop reading each line in a file, and then fork processes with the data of the line to a child. After N lines I want to wait for the child processes to end and continue with the next N lines, etc. It looks something like this: while ($w=<INP>) { # ignore file header if ($w=~m/^\D/) { next;} # get data from line chomp $w; @ws = split(/\s/,$w); $m = int($ws[0]); $d = int($ws[1]); $h = int($ws[2]); # only for some days in the year if (($m==3)and($d==15) or ($m==4)and($d==21) or ($m==7)and($d==18)) { die "could not fork" unless defined (my $pid = fork); unless ($pid) { some instructions here using $m, $d, $h ... } push @qpid,$pid; # when all processors are busy, wait for child processes if ($#qpid==($procs-1)) { for my $pid (@qpid) { waitpid $pid, 0; } reset 'q'; } } } close INP; This is not working. After the first round of processes I get some PID equal to 0, the @qpid array gets mixed up, and the file starts to get read at (apparently) random places, jumping back and forth. The end result is that most lines in the file get read two or three times. Any ideas? Thanks a lot in advance, S.

• Which Code Should Go Where in MVC Structure

  - by Oguz

  My problem is in somewhere between model and controller.Everything works perfect for me when I use MVC just for crud (create, read, update, delete).I have separate models for each database table .I access these models from controller , to crud them . For example , in contacts application,I have actions (create, read, update, delete) in controller(contact) to use model's (contact) methods (create, read, update, delete). The problem starts when I try to do something more complicated. There are some complex processes which I do not know where should I put them. For example , in registering user process. I can not just finish this process in user model because , I have to use other models too (sending mails , creating other records for user via other models) and do lots of complex validations via other models. For example , in some complex searching processes , I have to access lots of models (articles, videos, images etc.) Or, sometimes , I have to use apis to decide what I will do next or which database model I will use to record data So where is the place to do this complicated processes. I do not want to do them in controllers , Because sometimes I should use these processes in other controllers too. And I do not want to put these process in models because , I use models as database access layers .May be I am wrong,I want to know . Thank you for your answer .

• pthread condition variables on Linux, odd behaviour.

  - by janesconference

  Hi. I'm synchronizing reader and writer processes on Linux. I have 0 or more process (the readers) that need to sleep until they are woken up, read a resource, go back to sleep and so on. Please note I don't know how many reader processes are up at any moment. I have one process (the writer) that writes on a resource, wakes up the readers and does its business until another resource is ready (in detail, I developed a no starve reader-writers solution, but that's not important). To implement the sleep / wake up mechanism I use a Posix condition value, pthread_cond_t. The clients call a pthread_cond_wait() on the variable to sleep, while the server does a pthread_cond_broadcast() to wake them all up. As the manual says, I surround these two calls with a lock/unlock of the associated pthread mutex. The condition variable and the mutex are initialized in the server and shared between processes through a shared memory area (because I'm not working with threads, but with separate processes) an I'm sure my kernel / syscall support it (because I checked _POSIX_THREAD_PROCESS_SHARED). What happens is that the first client process sleeps and wakes up perfectly. When I start the second process, it blocks on its pthread_cond_wait() and never wakes up, even if I'm sure (by the logs) that pthread_cond_broadcast() is called. If I kill the first process, and launch another one, it works perfectly. In other words, the condition variable pthread_cond_broadcast() seems to wake up only one process a time. If more than one process wait on the very same shared condition variable, only the first one manages to wake up correctly, while the others just seem to ignore the broadcast. Why this behaviour? If I send a pthread_cond_broadcast(), every waiting process should wake up, not just one (and, however, not always the same one).

• Segmentation in Linux : Segmentation & Paging are redundant?

  - by claws

  Hello, I'm reading "Understanding Linux Kernel". This is the snippet that explains how Linux uses Segmentation which I didn't understand. Segmentation has been included in 80 x 86 microprocessors to encourage programmers to split their applications into logically related entities, such as subroutines or global and local data areas. However, Linux uses segmentation in a very limited way. In fact, segmentation and paging are somewhat redundant, because both can be used to separate the physical address spaces of processes: segmentation can assign a different linear address space to each process, while paging can map the same linear address space into different physical address spaces. Linux prefers paging to segmentation for the following reasons: Memory management is simpler when all processes use the same segment register values that is, when they share the same set of linear addresses. One of the design objectives of Linux is portability to a wide range of architectures; RISC architectures in particular have limited support for segmentation. All Linux processes running in User Mode use the same pair of segments to address instructions and data. These segments are called user code segment and user data segment , respectively. Similarly, all Linux processes running in Kernel Mode use the same pair of segments to address instructions and data: they are called kernel code segment and kernel data segment , respectively. Table 2-3 shows the values of the Segment Descriptor fields for these four crucial segments. I'm unable to understand 1st and last paragraph.

• Django URL Conf Returns Incorrect "Current URL"

  - by natnit

  I have a django app that is mostly done, and the URLs work perfectly when I run it with the manage.py runserver command. However, I've recently tried to get it running via lighttpd, and many links have stopped working. For example: http://mysite.com/races/32 should work, but instead throws this error message. Page not found (404) Request Method: GET Request URL: http://mysite.com/races/32 Using the URLconf defined in racetrack.urls, Django tried these URL patterns, in this order: ^admin/ ^create/$ ^races/$ ^races/(?P<race_id>\d+)/$ ^races/(?P<race_id>\d+)/manage/$ ^races/(?P<text>\w+)/$ ^user/(?P<kol_id>\d+)/$ ^$ ^login/$ ^logout/$ The current URL, 32, didn't match any of these. The request URL is accurate, but the last line (which displays the current URL) is giving 32 instead of races/32 as expected. Here is my urlconf: from django.conf.urls.defaults import * from django.contrib import admin admin.autodiscover() urlpatterns = patterns('racetrack.races.views', (r'^admin/', include(admin.site.urls)), (r'^create/$', 'create'), (r'^races/$', 'index'), (r'^races/(?P<race_id>\d+)/$', 'detail'), (r'^races/(?P<race_id>\d+)/manage/$', 'manage'), (r'^races/(?P<text>\w+)/$', 'index'), (r'^user/(?P<kol_id>\d+)/$', 'user'), # temporary for index page replace with welcome page (r'^$', 'index'), ) urlpatterns += patterns('django.contrib.auth.views', (r'^login/$', 'login', {'template_name': 'races/login.html'}), (r'^logout/$', 'logout', {'next_page': '/'}), ) Thank you.

• What does the Kernel Virtual Memory of each process contain?

  - by claws

  When say 3 programs (executables) are loaded into memory the layout might look something like this: I've following questions: Is the concept of Virtual Memory limited to user processes? Because, I am wondering where does the Operating System Kernel, Drivers live? How is its memory layout? I know its operating system specific make your choice (windows/linux). They say, on a 32 bit machine in a 4GB address space. Half of it (or more recently 1GB) is occupied by kernel. I can see in this diagram that "Kernel Virtual memory" is occupying 0xc0000000 - 0xffffffff (= 1 GB). Are they talking about this? or is it something else? Just want to confirm. What exactly does the Kernel Virtual Memory of each of these processes contain? What is its layout? When we do IPC we talk about shared memory. I don't see any memory shared between these processes. Where does it live? Resources (files, registries in windows) are global to all processes. So, the resource/file handle table must be in some global space. Which area would that be in? Where can I know more about this kernel side stuff.

• Looking for an issue tracker / project management software that automatically manages start/completion dates based on priority/relationships

  - by user361910

  So, a little background. We are a small company with a half-dozen developers. We have been evaluating many project management / issue tracking software packages (TRAC, Redmine, FogBugz, etc) and trying to create a decent process/workflow for managing projects, adding features, fixing bugs, etc. I'd like to think our requirements are similar to most other companies our size. Essentially, what this comes down to is 1) An easy way for the PM and developers to track projects, issues, bugs, etc 2) An easy way for the PM and admin/executives to get a birds-eye view of progress and easily manage timelines, schedules, and priorities. After trying TRAC, we moved to Redmine. We found Redmine to be easier than track to administer and the ability to have sub-projects and sub-tickets is great. However, the big problem we ran into is the fact that it is very difficult to manage schedules and timelines. It seems like it would be incredibly time-intensive to manage because you have to manually enter a start date, estimated time, and end date for each ticket, project, etc. So if you setup a month's schedule based on priorities, what are you supposed to do when a particular ticket/issue/subproject takes up more time than was estimated. Right now, it appears I would have to go back in and MANUALLY change the start/end date of every single item. What would be ideal is to be able to set priorities/dependencies and estimated time on tickets/milestones, and have the software automatically manage the start/end dates. Does anyone know how to get Redmine to do this, or recommend a different software package that can do something like this!

• Unexpected behaviour of Process.MainWindowHandle

  - by Ed Guiness

  I've been trying to understand Process.MainWindowHandle. According to MSDN; "The main window is the window that is created when the process is started. After initialization, other windows may be opened, including the Modal and TopLevel windows, but the first window associated with the process remains the main window." (Emphasis added) But while debugging I noticed that MainWindowHandle seemed to change value... which I wasn't expecting, especially after consulting the documentation above. To confirm the behaviour I created a standalone WinForms app with a timer to check the MainWindowHandle of the "DEVENV" (Visual Studio) process every 100ms. Here's the interesting part of this test app... IntPtr oldHWnd = IntPtr.Zero; void GetMainwindowHandle() { Process[] processes = Process.GetProcessesByName("DEVENV"); if (processes.Length!=1) return; IntPtr newHWnd = processes[0].MainWindowHandle; if (newHWnd != oldHWnd) { oldHWnd = newHWnd; textBox1.AppendText(processes[0].MainWindowHandle.ToString("X")+"\r\n"); } } private void timer1Tick(object sender, EventArgs e) { GetMainwindowHandle(); } You can see the value of MainWindowHandle changing when you (for example) click on a drop-down menu inside VS. Perhaps I've misunderstood the documentation. Can anyone shed light?

• Tools for managing code deployment/versioning for IIS / Windows enviroments

  - by RizwanK

  I've got a strong background in Linux and OSX, and just left a job where I was architecting systems based on those platforms. Now I've got a Windows Server running IIS that has a number of different websites that it hosts. Most of them are just a bunch of HTML, JS and Images, with some ASP for some customer tools. (Each website has a different set of customer tools, or they are the same tools, but with minor code changes between them.) I'm also adding a develop web server with the same code, but the 'bleeding edge' stuff. I need an effective way of managing changes and updates to the overall codebase (henceforth referring to both the images and the html and the asp, for all the sites). When a dev (or webmaster) checks in changes, I want it to show up automatically on the developer server, but should be manually pushed out to the live server. I'd be tempted to just make the websites SVN repositories, but I'd be concerned about the overhead of having the webdeveloper having to log into the server and trigger an SVN update via commandline/tortise (and heaven forbid, manage tags). Ideally I'd also manage IIS profile settings between the systems, but the major need is to be able to manage the process, and expose it to our ASP developer, and our webmaster, both of which are used to just FTPing up the files to the live site. So, any recommendations on tools (beyond some SVN hacking with BAT files + teaching the webmaster how to log into the server and do updates) or workflows that would help this out? I even considered an RPM type package (or some Windows equivalent, of course) to manage the live server, but that seems like a bit too much overhead. Thanks.

• Is a python dictionary the best data structure to solve this problem?

  - by mikip

  Hi I have a number of processes running which are controlled by remote clients. A tcp server controls access to these processes, only one client per process. The processes are given an id number in the range of 0 - n-1. Were 'n' is the number of processes. I use a dictionary to map this id to the client sockets file descriptor. On startup I populate the dictionary with the ids as keys and socket fd of 'None' for the values, i.e no clients and all pocesses are available When a client connects, I map the id to the sockets fd. When a client disconnects I set the value for this id to None, i.e. process is available. So everytime a client connects I have to check each entry in the dictionary for a process which has a socket fd entry of None. If there are then the client is allowed to connect. This solution does not seem very elegant, are there other data structures which would be more suitable for solving this? Thanks

• Installing a DHCP Service On Win2k8 ( Windows Server 2008 )

  - by Akshay Deep Lamba

  Introduction Dynamic Host Configuration Protocol (DHCP) is a core infrastructure service on any network that provides IP addressing and DNS server information to PC clients and any other device. DHCP is used so that you do not have to statically assign IP addresses to every device on your network and manage the issues that static IP addressing can create. More and more, DHCP is being expanded to fit into new network services like the Windows Health Service and Network Access Protection (NAP). However, before you can use it for more advanced services, you need to first install it and configure the basics. Let’s learn how to do that. Installing Windows Server 2008 DHCP Server Installing Windows Server 2008 DCHP Server is easy. DHCP Server is now a “role” of Windows Server 2008 – not a windows component as it was in the past. To do this, you will need a Windows Server 2008 system already installed and configured with a static IP address. You will need to know your network’s IP address range, the range of IP addresses you will want to hand out to your PC clients, your DNS server IP addresses, and your default gateway. Additionally, you will want to have a plan for all subnets involved, what scopes you will want to define, and what exclusions you will want to create. To start the DHCP installation process, you can click Add Roles from the Initial Configuration Tasks window or from Server Manager à Roles à Add Roles. Figure 1: Adding a new Role in Windows Server 2008 When the Add Roles Wizard comes up, you can click Next on that screen. Next, select that you want to add the DHCP Server Role, and click Next. Figure 2: Selecting the DHCP Server Role If you do not have a static IP address assigned on your server, you will get a warning that you should not install DHCP with a dynamic IP address. At this point, you will begin being prompted for IP network information, scope information, and DNS information. If you only want to install DHCP server with no configured scopes or settings, you can just click Next through these questions and proceed with the installation. On the other hand, you can optionally configure your DHCP Server during this part of the installation. In my case, I chose to take this opportunity to configure some basic IP settings and configure my first DHCP Scope. I was shown my network connection binding and asked to verify it, like this: Figure 3: Network connection binding What the wizard is asking is, “what interface do you want to provide DHCP services on?” I took the default and clicked Next. Next, I entered my Parent Domain, Primary DNS Server, and Alternate DNS Server (as you see below) and clicked Next. Figure 4: Entering domain and DNS information I opted NOT to use WINS on my network and I clicked Next. Then, I was promoted to configure a DHCP scope for the new DHCP Server. I have opted to configure an IP address range of 192.168.1.50-100 to cover the 25+ PC Clients on my local network. To do this, I clicked Add to add a new scope. As you see below, I named the Scope WBC-Local, configured the starting and ending IP addresses of 192.168.1.50-192.168.1.100, subnet mask of 255.255.255.0, default gateway of 192.168.1.1, type of subnet (wired), and activated the scope. Figure 5: Adding a new DHCP Scope Back in the Add Scope screen, I clicked Next to add the new scope (once the DHCP Server is installed). I chose to Disable DHCPv6 stateless mode for this server and clicked Next. Then, I confirmed my DHCP Installation Selections (on the screen below) and clicked Install. Figure 6: Confirm Installation Selections After only a few seconds, the DHCP Server was installed and I saw the window, below: Figure 7: Windows Server 2008 DHCP Server Installation succeeded I clicked Close to close the installer window, then moved on to how to manage my new DHCP Server. How to Manage your new Windows Server 2008 DHCP Server Like the installation, managing Windows Server 2008 DHCP Server is also easy. Back in my Windows Server 2008 Server Manager, under Roles, I clicked on the new DHCP Server entry. Figure 8: DHCP Server management in Server Manager While I cannot manage the DHCP Server scopes and clients from here, what I can do is to manage what events, services, and resources are related to the DHCP Server installation. Thus, this is a good place to go to check the status of the DHCP Server and what events have happened around it. However, to really configure the DHCP Server and see what clients have obtained IP addresses, I need to go to the DHCP Server MMC. To do this, I went to Start à Administrative Tools à DHCP Server, like this: Figure 9: Starting the DHCP Server MMC When expanded out, the MMC offers a lot of features. Here is what it looks like: Figure 10: The Windows Server 2008 DHCP Server MMC The DHCP Server MMC offers IPv4 & IPv6 DHCP Server info including all scopes, pools, leases, reservations, scope options, and server options. If I go into the address pool and the scope options, I can see that the configuration we made when we installed the DHCP Server did, indeed, work. The scope IP address range is there, and so are the DNS Server & default gateway. Figure 11: DHCP Server Address Pool Figure 12: DHCP Server Scope Options So how do we know that this really works if we do not test it? The answer is that we do not. Now, let’s test to make sure it works. How do we test our Windows Server 2008 DHCP Server? To test this, I have a Windows Vista PC Client on the same network segment as the Windows Server 2008 DHCP server. To be safe, I have no other devices on this network segment. I did an IPCONFIG /RELEASE then an IPCONFIG /RENEW and verified that I received an IP address from the new DHCP server, as you can see below: Figure 13: Vista client received IP address from new DHCP Server Also, I went to my Windows 2008 Server and verified that the new Vista client was listed as a client on the DHCP server. This did indeed check out, as you can see below: Figure 14: Win 2008 DHCP Server has the Vista client listed under Address Leases With that, I knew that I had a working configuration and we are done!
