  • A Letter for Your CEO About Social Marketing’s Future

    - by Mike Stiles
    We’ll leave it to you to decide if or how to sneak this in front of them. Dear Chief: This social marketing thing looks serious. It’s gone beyond having a Facebook page and putting our info and a few promotions on it. It’s seriously disrupting how we’ve always done marketing. And its implications reach well beyond marketing. My concern is that we stay positioned ahead of these changes and are prepared to embrace, adapt and capitalize on these new capabilities as opposed to spending valuable time and money trying to shoehorn social into “the way we’ve always done things.” I’m also concerned about what happens if our competition executes on this before we do. The days of being able to impose our ad messaging on the masses to great effect are numbered. The public now has the tech tools and ability to filter out things that are irrelevant to them. And frankly, spending ad dollars to reach unlikely prospects isn’t the most efficient path for us either. Today, our customers have to genuinely love what we do. That starts with a renewed, customer-centric focus on the quality and usability of our product. If their experience with it is bad, they now have very connected, loud voices that will testify against us. We can’t afford that. Next, their customer service experience, before and after the sale, has to be a pleasant surprise. That requires truly knowing our customers and listening to them. Lip service won’t cut it. We have to get and use as much data on the customer as possible, interact with them wherever they want to interact with us, and commit to impressing them. If we do, they’ll get out there and advertise for us. Since peer-to-peer recommendation is the most effective marketing, that’s money in the bank. Social marketing is about forming relationships, same as how individuals use social. We want them to know us, trust us, and get real value from knowing us. That requires honesty and transparency that before now might have been uncomfortable. I propose that if we clearly make everything we do about our customers’ wants and needs, we’ll have nothing to hide. It will solidify customer loyalty, retention, and thus, revenue. These things can’t happen without certain tools and structural changes in the organization. There are social cloud platforms that integrate social management into all of the necessary areas: CRM, customer service, sales, marketing automation, content marketing, ecommerce, etc. This is will give us a real-time, complete view of the customer so their every interaction with us is attentive, personalized, accurate, relevant, and satisfying. Without it, we’re just a collage of disjointed systems, each gathering data that informs only its own departmental silo. The customer is voluntarily giving us everything we need to know about them to win them over, but we have to start listening and putting the pieces together. There’s still time. Brands are coming to terms with this transition to the socially enabled enterprise, but so far they aren’t moving very fast. Like us, they’re dealing with long-entrenched technologies and processes. CMO’s and CIO’s have to form new partnerships. Content operations have to be initiated and properly staffed and funded. Various departments must be able to utilize interconnected big data. What will separate the winners from the losers? Well chief, that’s why I’m writing you. It’s in your hands. These initiatives won’t get the kind of priority and seriousness that inspire actual deadlines & action unless they come from your desk. You have to be the champion of customer centricity. You have to be our change agent. You have to be our innovator. Otherwise, it’s going to be business as usual, and that puts us in a very vulnerable place. Sincerely, Your Team @mikestilesPhoto: Gary Scott, stock.xchng

  • Can't Remote into Windows Server

    - by Brian
    Hello, I have a Dell server wired into the router. I was able to connect to it with my laptop (laptop is wireless) before my router died. My verizon router went kaput, and I got everything else back up and running on the wireless network other than the remoting in feature, even though I can access the server through windows explorer just fine. Any ideas why? What do I need to check? UPDATE: Interesting scenario, Network Discovery is off; I turn it on and save, but for some reason, even after that, network discovery is turning itself off... no idea why that is happening? Thanks.

  • Why aren't RemoteApp icons showing up

    - by Andy Schneider
    I have a Windows 2008 R2 server running RDS. I have installed and configured RemoteApp to publish applications with RDS Web Access. When I browse to https://servernname.domain.local/RDWeb I can log in and get to the RemoteApp Programs tab, but there are no icons or apps to click on. I have added a bunch of apps in Remote App manager and they are all enabled for RD Web Access. Also, I am an administrator on the server.

  • Difference between Xen PV, Xen KVM and HVM?

    - by JP19
    Hi, I know that Xen is usually better than OpenVZ as the provider cannot oversell in Xen. However, what is the difference between Xen PV, Xen KVM and HVM (I was going through this provider's specs? Which one is better for what purposes and why? Edit: For an end-user who will just be hosting websites, which is better? From efficiency or other point of view, is there any advantage of one over the other?

  • Thomas Kurian's COLLABORATE Keynote: Process not Product

    - by Aaron Lazenby
    Right off the bat, Oracle's Senior Vice President, Server Technologies Development made his purpose very clear: demonstrate how the elements of the Oracle product stack are evolving (and integrating) together. There are some great details about the new functionality of each Oracle application line and how the different products sync and interact. The lifecycle charts in Kurian's presentation illustrate how data can flow from an Oracle Demantra into Oracle E-Business Suite and back out to an Oracle Agile system to support value chain planning. With so many products at play in the enterprise, Kurian shows that if you trust that your systems can work together, IT strategy becoming much more about managing business process than managing software product.

  • Dedicate a NIC to a Virtualbox VM

    - by John Gardeniers
    On a machine with multiple NICs, running either Windows or Linux, is it possible to dedicate a NIC to a VM such that the host won't even try to use it for itself? I suspect it isn't even possible but if it is, which OS and version and just how would I set it up? The reason for this, apart from academic curiosity, is that I'm trying to set up a network lab for testing purposes. I currently have only a single spare machine, otherwise this wouldn't be an issue. One of the VMs will be the firewall for this lab network, so will need a dedicated NIC for the WAN interface. Neither ESXi nor Xen server will run on the machine, so I have to use a host OS.

  • Terminal Services - what does this message mean ?

    - by southof40
    Hi - I'm responsible for a W2003 server. I'm trying to switch on terminal services. When I do so I get a message that includes the text : "If you continue with this installation, programs that are already installed on your server will no longer work and will have to be reinstalled" Surely that doesn't mean what it appears to mean ? I just want one extra person to be able to access the machine in the same way that currently two administrators do (via "Remote Administration") only I want all three to be able to do simultaneously. When I bought the extra TS license I thought I was just buying the right to have one extra user. Is doing this really going to trash everything on the machine ?

  • ZFS - zpool ARC cache plus L2ARC benchmarking

    - by jemmille
    I have been doing lots of I/O testing on a ZFS system I will eventually use to serve virtual machines. I thought I would try adding SSD's for use as cache to see how much faster I can get the read speed. I also have 24GB of RAM in the machine that acts as ARC. vol0 is 6.4TB and the cache disks are 60GB SSD's. The zvol is as follows: pool: vol0 state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM vol0 ONLINE 0 0 0 c1t8d0 ONLINE 0 0 0 cache c3t5001517958D80533d0 ONLINE 0 0 0 c3t5001517959092566d0 ONLINE 0 0 0 The issue is I'm not seeing any difference with the SSD's installed. I've tried bonnie++ benchmarks and some simple dd commands to write a file then read the file. I have run benchmarks before and after adding the SSD's. I've ensured the file sizes are at least double my RAM so there is no way it can all get cached locally. Am I missing something here? When am I going to see benefits of having all that cache? Am I simply not under these circumstances? Are the benchmark programs not good for testing the effect of cache because of the the way (and what) it writes and reads?

  • Virtual Sound Card for Windows Server?

    - by Ian Boyd
    i have some software running on a server which requires a sound card to be installed. i'm trying to find a virtual, or emulated, sound card driver for Windows 2000 Server. It doesn't have to play anything, send streams anywhere, or do anything. It just has to be there. Note: This is a physical machine, but i want the solution that will port to a Microsoft Virtual Server machine running Windows 2000 Server. (in other words, buying a sound card will not work) i've already tried the REaudio driver from MixW; it does not work (no sound card virtually appears in the system). Update: 1k views? Obviously people are finding it an interesting question to keep stumbling across it. Up-vote it!

  • VirtualBox guest network lost after host disconnects

    - by webjunk
    I am running VirtualBox both on a Snow Leopard OSX host machine and on a Windows Vista host machine. Whenever my host machines lose internet connection the guest machines seem to lose internet connectivity permanently even after the host connection to the Internet is reestablished. Resetting guest networking on the guest os, disconnecting cable via host virtualbox settings, and even restarting the guest OS do not help at all. The guest no longer can access the Internet. The only solution is restarting VirtualBox itself while the host is connected to the Internet. This really gets to be a pain when the host goes into sleep mode or I disconnect my laptop at work and then reconnect at home. Guests are setup with NAT networking. It affects guest machines with both Ubuntu and Windows XP OS'es. Is this expected behavior? Does anyone know of a fix? Or am I setup incorrectly?

  • How does it hurt to use Linux (Ubuntu) as a guest OS for all my tasks?

    - by sauparna
    I have a machine running Windows, where the disk has two partitions C (50 GB) and D (250GB). I do research in Information Retrieval and need to work with a large corpus (more than 50 GB) and in Linux. So if I want to install Linux on the existing system, keeping the Windows installation intact, will it be fine to run it in a virtual box? (say, QEMU, VMWare, etc.) An alternative is using Wubi. In that case the Linux installation has to be on drive C. Then, if I keep a small Linux installation (say 5GB) on C, and my corpus on D (mounted in Linux), how will it affect the performance of my programs which would be accessing the mounted Windows drive D. Is it feasible to use Linux this way? Which of the above is better if at all they are a way out? Note : Since my post in July 2010, I have been using and have tried several ways of maintaining a disk-image that I can mount in Linux. I had a 100GB qcow2 disk and a 100GB raw disk, both formatted to an EXT3 file system. I was mounting and connecting to the qcow2 disk using qemu-nbd. The problem was that every now and then, the connection to the disk would get lost and the running programs would throw disk I/O errors. The raw disk would mount and work fine as a loop mounted device, but when writing data to it, the mount.ntfs program would hog the CPU and the process would take an enormous amount of time. I was in fact running make on a piece of software located on this raw disk, and after a point of time make was waiting while mount.ntfs would show 100% CPU usage.

  • RAID 0 performance gains?

    - by NickAldwin
    I'm building a new computer over the summer. I'm fairly competent in computer hardware, and am thus building the computer from scratch. I have everything planned out, but I was wondering about RAID. I asked which RAID I should use earlier, but now that it's pretty clear that RAID 1 isn't really that great, I think I'll go with cloud-backup instead of disk-redundancy. However, I still face a choice: use two 1TB drives as two 1TB drives, or combine them into a RAID 0 striped array. Is there any performance gain at all? I know that if one drive dies, everything is gone, so is the performance gain worth it? I'm building a pretty advanced computer, with SLI video cards and a fast CPU, so I'm thinking RAID 0 would give me some good hard drive performance. From your experience, is RAID 0 viable?

  • CRMIT’s HIGH VALUE CRM++ PLUGINS FOR CRM On DEMAND

    - by Soumo Das
    Customer satisfaction and experience being the two most considerable factors, these days businesses are on the lookout for automation tools that are world class, agile and keep quality at its core. CRMIT has developed such tools using cutting edge technologies and abstracting industry best practices and R&D.  Self Service Portal  With customers being so meticulous about regular updates and reliable access to their data, administrators just cannot think of walking a thin line. Surviving without a resource that provides a track of customer requirements for services available 24 x 7 can severely affect the productivity. In such a scenario, CRMIT’s Self Service Portal (SSP) is the best solution. This not only tracks the required customer data, but also allows companies to stay in tune with their employees, vendors and stakeholders.   One can directly sign up to become a CRMOD contact and SSP user. One need not use the database, as operations and interactions are d at run time. This is a fully configurable solution that tracks results periodically, thus making it easy for end users. It also offers better security and data visibility that enables users to progress smoothly. Quote and Order Management   When dealing with quotes, contracts and orders becomes complicated, only Quote & Order Management can work as a one-stop solution. CRMIT offers this great tool for managing all this information and for taking care of customer orders and service requirements.  This CRM On Demand plug-in allows one to create a new quote or copy the existing one. Products can be directly added from the product list of CRMOD and the pricing is calculated automatically. Quote can be generated and mailed to the external users in PDF, HTML and XLS formats. This not only allows management of quotes in an enhanced manner, but also supports various billing and tax calculation features that make work effortless.    Report Scheduler  When it comes to analyzing and providing statistics of various business processes currently running in an organization, one cannot depend on manual updates, which sometimes may be inaccurate or even delayed. CRMIT provides a SaaS based powerful solution - Report Scheduler - that allows CRM users to schedule reports as per the frequencies and then receive them as email attachments at the scheduled time.   With this powerful tool, administrators can control the report scheduler for assigning specific reports to specific users. After that, users can login and schedule any assigned report for viewing at particular intervals on monthly, weekly or daily basis. Additionally, users can also copy the mail to external users and can choose the preferred format. The best part is that sharing business data with third party become easy with this and for viewing reports, users need not log into their CRMOD account.  CRM On Demand Offline Solution CRM On-Demand Offline is another great CRM++ extension that allows one to work in both online and offline modes. Synchronizing both the modes is absolutely easy and offers ease while working. CRM OD offline works as an automation tool that not only improves efficiency, but also works as a backup in most cases. It is readily available as a windows application installer and requires users to be online only while validating and synchronizing. The best part is that working in the offline mode also works as a backup.

  • Who should ‘own’ the Enterprise Architecture?

    - by Michael Glas
    I recently had a discussion around who should own an organization’s Enterprise Architecture. It was spawned by an article titled “Busting CIO Myths” in CIO magazine1 where the author interviewed Jeanne Ross, director of MIT's Center for Information Systems Research and co-author of books on enterprise architecture, governance and IT value.In the article Jeanne states that companies need to acknowledge that "architecture says everything about how the company is going to function, operate, and grow; the only person who can own that is the CEO". "If the CEO doesn't accept that role, there really can be no architecture."The first question that came up when talking about ownership was whether you are talking about a person, role, or organization (there are pros and cons to each, but in general, I like to assign accountability to as few people as possible). After much thought and discussion, I came to the conclusion that we were answering the wrong question. Instead of talking about ownership we were talking about responsibility and accountability, and the answer varies depending on the particular role of the organization’s Enterprise Architecture and the activities of the enterprise architect(s).Instead of looking at just who owns the architecture, think about what the person/role/organization should do. This is one possible scenario (thanks to Bob Covington): The CEO should own the Enterprise Strategy which guides the business architecture. The Business units should own the business processes and information which guide the business, application and information architectures. The CIO should own the technology, IT Governance and the management of the application and information architectures/implementations. The EA Governance Team owns the EA process.  If EA is done well, the governance team consists of both IT and the business. While there are many more roles and responsibilities than listed here, it starts to provide a clearer understanding of ‘ownership’. Now back to Jeanne’s statement that the CEO should own the architecture. If you agree with the statement about what the architecture is (and I do agree), then ultimately the CEO does need to own it. However, what we ended up with was not really ownership, but more statements around roles and responsibilities tied to aspects of the enterprise architecture. You can debate the semantics of ownership vs. responsibility and accountability, but in the end the important thing is to come to a clearer understanding that is easily communicated (and hopefully measured) around the question “Who owns the Enterprise Architecture”.The next logical step . . . create a RACI matrix that details the findings . . . but that is a step that each organization needs to do on their own as it will vary based on current EA maturity, company culture, and a variety of other factors. Who ‘owns’ the Enterprise Architecture in your organization? 1 CIO Magazine Article (Busting CIO Myths): http://www.cio.com/article/704943/Busting_CIO_Myths Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • Following the Thread in OSB

    - by Antony Reynolds
    Threading in OSB The Scenario I recently led an OSB POC where we needed to get high throughput from an OSB pipeline that had the following logic: 1. Receive Request 2. Send Request to External System 3. If Response has a particular value   3.1 Modify Request   3.2 Resend Request to External System 4. Send Response back to Requestor All looks very straightforward and no nasty wrinkles along the way.  The flow was implemented in OSB as follows (see diagram for more details): Proxy Service to Receive Request and Send Response Request Pipeline   Copies Original Request for use in step 3 Route Node   Sends Request to External System exposed as a Business Service Response Pipeline   Checks Response to Check If Request Needs to Be Resubmitted Modify Request Callout to External System (same Business Service as Route Node) The Proxy and the Business Service were each assigned their own Work Manager, effectively giving each of them their own thread pool. The Surprise Imagine our surprise when, on stressing the system we saw it lock up, with large numbers of blocked threads.  The reason for the lock up is due to some subtleties in the OSB thread model which is the topic of this post.   Basic Thread Model OSB goes to great lengths to avoid holding on to threads.  Lets start by looking at how how OSB deals with a simple request/response routing to a business service in a route node. Most Business Services are implemented by OSB in two parts.  The first part uses the request thread to send the request to the target.  In the diagram this is represented by the thread T1.  After sending the request to the target (the Business Service in our diagram) the request thread is released back to whatever pool it came from.  A multiplexor (muxer) is used to wait for the response.  When the response is received the muxer hands off the response to a new thread that is used to execute the response pipeline, this is represented in the diagram by T2. OSB allows you to assign different Work Managers and hence different thread pools to each Proxy Service and Business Service.  In out example we have the “Proxy Service Work Manager” assigned to the Proxy Service and the “Business Service Work Manager” assigned to the Business Service.  Note that the Business Service Work Manager is only used to assign the thread to process the response, it is never used to process the request. This architecture means that while waiting for a response from a business service there are no threads in use, which makes for better scalability in terms of thread usage. First Wrinkle Note that if the Proxy and the Business Service both use the same Work Manager then there is potential for starvation.  For example: Request Pipeline makes a blocking callout, say to perform a database read. Business Service response tries to allocate a thread from thread pool but all threads are blocked in the database read. New requests arrive and contend with responses arriving for the available threads. Similar problems can occur if the response pipeline blocks for some reason, maybe a database update for example. Solution The solution to this is to make sure that the Proxy and Business Service use different Work Managers so that they do not contend with each other for threads. Do Nothing Route Thread Model So what happens if there is no route node?  In this case OSB just echoes the Request message as a Response message, but what happens to the threads?  OSB still uses a separate thread for the response, but in this case the Work Manager used is the Default Work Manager. So this is really a special case of the Basic Thread Model discussed above, except that the response pipeline will always execute on the Default Work Manager.   Proxy Chaining Thread Model So what happens when the route node is actually calling a Proxy Service rather than a Business Service, does the second Proxy Service use its own Thread or does it re-use the thread of the original Request Pipeline? Well as you can see from the diagram when a route node calls another proxy service then the original Work Manager is used for both request pipelines.  Similarly the response pipeline uses the Work Manager associated with the ultimate Business Service invoked via a Route Node.  This actually fits in with the earlier description I gave about Business Services and by extension Route Nodes they “… uses the request thread to send the request to the target”. Call Out Threading Model So what happens when you make a Service Callout to a Business Service from within a pipeline.  The documentation says that “The pipeline processor will block the thread until the response arrives asynchronously” when using a Service Callout.  What this means is that the target Business Service is called using the pipeline thread but the response is also handled by the pipeline thread.  This implies that the pipeline thread blocks waiting for a response.  It is the handling of this response that behaves in an unexpected way. When a Business Service is called via a Service Callout, the calling thread is suspended after sending the request, but unlike the Route Node case the thread is not released, it waits for the response.  The muxer uses the Business Service Work Manager to allocate a thread to process the response, but in this case processing the response means getting the response and notifying the blocked pipeline thread that the response is available.  The original pipeline thread can then continue to process the response. Second Wrinkle This leads to an unfortunate wrinkle.  If the Business Service is using the same Work Manager as the Pipeline then it is possible for starvation or a deadlock to occur.  The scenario is as follows: Pipeline makes a Callout and the thread is suspended but still allocated Multiple Pipeline instances using the same Work Manager are in this state (common for a system under load) Response comes back but all Work Manager threads are allocated to blocked pipelines. Response cannot be processed and so pipeline threads never unblock – deadlock! Solution The solution to this is to make sure that any Business Services used by a Callout in a pipeline use a different Work Manager to the pipeline itself. The Solution to My Problem Looking back at my original workflow we see that the same Business Service is called twice, once in a Routing Node and once in a Response Pipeline Callout.  This was what was causing my problem because the response pipeline was using the Business Service Work Manager, but the Service Callout wanted to use the same Work Manager to handle the responses and so eventually my Response Pipeline hogged all the available threads so no responses could be processed. The solution was to create a second Business Service pointing to the same location as the original Business Service, the only difference was to assign a different Work Manager to this Business Service.  This ensured that when the Service Callout completed there were always threads available to process the response because the response processing from the Service Callout had its own dedicated Work Manager. Summary Request Pipeline Executes on Proxy Work Manager (WM) Thread so limited by setting of that WM.  If no WM specified then uses WLS default WM. Route Node Request sent using Proxy WM Thread Proxy WM Thread is released before getting response Muxer is used to handle response Muxer hands off response to Business Service (BS) WM Response Pipeline Executes on Routed Business Service WM Thread so limited by setting of that WM.  If no WM specified then uses WLS default WM. No Route Node (Echo functionality) Proxy WM thread released New thread from the default WM used for response pipeline Service Callout Request sent using proxy pipeline thread Proxy thread is suspended (not released) until the response comes back Notification of response handled by BS WM thread so limited by setting of that WM.  If no WM specified then uses WLS default WM. Note this is a very short lived use of the thread After notification by callout BS WM thread that thread is released and execution continues on the original pipeline thread. Route/Callout to Proxy Service Request Pipeline of callee executes on requestor thread Response Pipeline of caller executes on response thread of requested proxy Throttling Request message may be queued if limit reached. Requesting thread is released (route node) or suspended (callout) So what this means is that you may get deadlocks caused by thread starvation if you use the same thread pool for the business service in a route node and the business service in a callout from the response pipeline because the callout will need a notification thread from the same thread pool as the response pipeline.  This was the problem we were having. You get a similar problem if you use the same work manager for the proxy request pipeline and a business service callout from that request pipeline. It also means you may want to have different work managers for the proxy and business service in the route node. Basically you need to think carefully about how threading impacts your proxy services.

  • How do I install a CentOS 5.5 in Xenserver?

    - by deweller
    When I try to install CentOS 5.5 in a new VM, I get an error that the installer is unable to retrieve stage2.img. I have verified the URL and I am able to download this file from a web browser. I suspect it is a networking/routing issue, but I can't figure out what is wrong. This is a new install of XenServer 5.6 on a new server. This server is remote, so I don't have physical access to the box - only ssh access. Can anyone give me some tips on what might be wrong here? Do I need to do something special to get a net install to work? For what its worth, I see the same error trying to install Debian Woody using a similar process. Thanks.
