  • iStack for iPad

    - by Jonathan
    The below image is the current, and hopefully final, look of the front screen, the app will remember which stack site you have chosen so the user will only see this screen the first time, but they can always go back and change it. The red bar is only there when a new site is added (the StackOverflow is just a test as no site has been added since I implemented this) and can be gotten rid of by tapping the X on the right side (which isn't in the screenshot). Each column now has an edit button where the sites can be rearranged and moved from favourites to non favourites and this is persistent between app launches, moving a site in one column moves it in all of them. I've removed site icons in order to put them in properly so they load lazily and theres no UI freezing. Printing Functionality all implemented and working, thanks to systempuntoout's stackprinter.com works with AirPrint, which means this app will be iOS 4.2 minimum. Current features: 3 columns Email link to question, open in safari and copy link actions History for both questions and sites visited In app notification (red bar at the top) when a new site makes it into beta. StackPrinter in the app, without needing safari, and AirPrint functionality. Facebook Intergration Planned: Local Favourites Watching (a list of questions your watching, like short term favourites, with eventually push notifications) Web service to access local favourites and watches on non-iPad devices. Twitter integration. Safari bookmarklet to open question in iStack from safari In app notification for when site progresses from beta to normal. In app notification history

  • Ask the Readers: How Fast is Your Internet Connection?

    - by Mysticgeek
    The federal government recently announced a broadband initiative that calls for 260 million homes to have 100Mbps Internet connections by the year 2020. This got us wondering, how fast is your current Internet connection? Photo by roland When it comes to the speed of our Internet connection, we all want the maximum possible. The FCC recently announced their National Broadband Plan, which is an initiative to improve the Internet infrastructure in the United States and provide higher speeds to everyone. You’ve also undoubtedly heard the news about Google getting into the mix with their program to bring ultra high-speed fiber broadband to 50,000 users in select cities. While we wait for those programs to come into fruition, we thought it would be cool to check out what kinds of speeds you’re getting now. Test Your Internet Connection Speed There are several sites out there you can use to test your Internet speeds, but probably the best site is Speedtest.net. It’s easy to use, and allows you test download and upload speeds to and from various locations in the US and throughout the world. If you already know the speeds you’re getting leave a comment and let us know. If you use Speedtest.com, just keep in mind that our comment system won’t allow you to copy their result links, but you can simply tell us what you get in the results. We’re especially interested in the results of those of you who have Verizon FIOS or Comcast’s “Ultra” service. Leave a comment and join in the discussion!

  • How to Upload Really Large Files to SkyDrive, Dropbox, or Email

    - by Matthew Guay
    Do you need to upload a very large file to store online or email to a friend? Unfortunately, whether you’re emailing a file or using online storage sites like SkyDrive, there’s a limit on the size of files you can use. Here’s how to get around the limits. Skydrive only lets you add files up to 50 MB, and while the Dropbox desktop client lets you add really large files, the web interface has a 300 MB limit, so if you were on another PC and wanted to add giant files to your Dropbox, you’d need to split them. This same technique also works for any file sharing service—even if you were sending files through email. There’s two ways that you can get around the limits—first, by just compressing the files if you’re close to the limit, but the second and more interesting way is to split up the files into smaller chunks. Keep reading for how to do both.

  • Cant logon to domain over site-to-site vpn

    - by 3molo
    Tied together branch office with main office over two Cisco ASAs. The (internal) networks on either side can communicate with the other. I can ping, use the DC's DNS service and even join a domain on a new client. I can't however logon, I get the "domain controller is not available" error message on client. I find nothing peculiar in DC's event logs. Sicne it's site-to-site (with ping), it's always up so it should work. No firewall rules (except allow any any) between the two networks (of either side). Main site internal net: 10.10.10.0/24 Branch office net: 10.180.3.0/24 Am I overlooking something here? Where should I start investigating this?d

  • VPN authentication and MAC addresses

    - by zakk
    I have to set up a VPN (various clients connecting to a web service on a server, which is also the VPN server) and I want to make sure that no user will share his/her credentials with third parties. I know that this problem is not solvable completely, but I'd want to set up some additional security checks... Some idea I have: 1) An additional check on MAC address, but... are MAC addresses preserved thru VPN? 2) Some kind of extra identification of the client (User Agent, open ports, I want to make sure that is the very same client I authorized). 3) I would like to avoid commercial solutions like a security token... I realize it would be the perfect solution, but it will be to expensive, I suppose... Do you feel that these options are viable? Do you have any other ideas? Thanks in advance for your replies!

  • How can I speed up my Windows Server 2008 VPN Connection?

    - by Pure.Krome
    So I've installed VPN service that comes with Windows Server 2008. Works perfectly, etc. When a client remote desktops to one of the private servers at the office, via VPN .. it's pretty slow. Now - how long is a piece of string? So before I get all the obligatory checks, I'll list the things from Mr. Obvious: Our modem/router (fritz!box) has a data/graph that shows incoming and outbound bandwidth. Both directions are barely getting used when a client has RDP'd via VPN. Our office internet connection is running at 21,9 Mbit/s download 1,3 Mbit/s upload. I feel like it's maxing at .. modem speeds ?? Is there any tricks I can do to confirm this and possibly even fix this?

  • The Red Gate and .NET Reflector Debacle

    - by Rick Strahl
    About a month ago Red Gate – the company who owns the NET Reflector tool most .NET devs use at one point or another – decided to change their business model for Reflector and take the product from free to a fully paid for license model. As a bit of history: .NET Reflector was originally created by Lutz Roeder as a free community tool to inspect .NET assemblies. Using Reflector you can examine the types in an assembly, drill into type signatures and quickly disassemble code to see how a particular method works.  In case you’ve been living under a rock and you’ve never looked at Reflector, here’s what it looks like drilled into an assembly from disk with some disassembled source code showing: Note that you get tons of information about each element in the tree, and almost all related types and members are clickable both in the list and source view so it’s extremely easy to navigate and follow the code flow even in this static assembly only view. For many year’s Lutz kept the the tool up to date and added more features gradually improving an already amazing tool and making it better. Then about two and a half years ago Red Gate bought the tool from Lutz. A lot of ruckus and noise ensued in the community back then about what would happen with the tool and… for the most part very little did. Other than the incessant update notices with prominent Red Gate promo on them life with Reflector went on. The product didn’t die and and it didn’t go commercial or to a charge model. When .NET 4.0 came out it still continued to work mostly because the .NET feature set doesn’t drastically change how types behave.  Then a month back Red Gate started making noise about a new Version Version 7 which would be commercial. No more free version - and a shit storm broke out in the community. Now normally I’m not one to be critical of companies trying to make money from a product, much less for a product that’s as incredibly useful as Reflector. There isn’t day in .NET development that goes by for me where I don’t fire up Reflector. Whether it’s for examining the innards of the .NET Framework, checking out third party code, or verifying some of my own code and resources. Even more so recently I’ve been doing a lot of Interop work with a non-.NET application that needs to access .NET components and Reflector has been immensely valuable to me (and my clients) if figuring out exact type signatures required to calling .NET components in assemblies. In short Reflector is an invaluable tool to me. Ok, so what’s the problem? Why all the fuss? Certainly the $39 Red Gate is trying to charge isn’t going to kill any developer. If there’s any tool in .NET that’s worth $39 it’s Reflector, right? Right, but that’s not the problem here. The problem is how Red Gate went about moving the product to commercial which borders on the downright bizarre. It’s almost as if somebody in management wrote a slogan: “How can we piss off the .NET community in the most painful way we can?” And that it seems Red Gate has a utterly succeeded. People are rabid, and for once I think that this outrage isn’t exactly misplaced. Take a look at the message thread that Red Gate dedicated from a link off the download page. Not only is Version 7 going to be a paid commercial tool, but the older versions of Reflector won’t be available any longer. Not only that but older versions that are already in use also will continually try to update themselves to the new paid version – which when installed will then expire unless registered properly. There have also been reports of Version 6 installs shutting themselves down and failing to work if the update is refused (I haven’t seen that myself so not sure if that’s true). In other words Red Gate is trying to make damn sure they’re getting your money if you attempt to use Reflector. There’s a lot of temptation there. Think about the millions of .NET developers out there and all of them possibly upgrading – that’s a nice chunk of change that Red Gate’s sitting on. Even with all the community backlash these guys are probably making some bank right now just because people need to get life to move on. Red Gate also put up a Feedback link on the download page – which not surprisingly is chock full with hate mail condemning the move. Oddly there’s not a single response to any of those messages by the Red Gate folks except when it concerns license questions for the full version. It puzzles me what that link serves for other yet than another complete example of failure to understand how to handle customer relations. There’s no doubt that that all of this has caused some serious outrage in the community. The sad part though is that this could have been handled so much less arrogantly and without pissing off the entire community and causing so much ill-will. People are pissed off and I have no doubt that this negative publicity will show up in the sales numbers for their other products. I certainly hope so. Stupidity ought to be painful! Why do Companies do boneheaded stuff like this? Red Gate’s original decision to buy Reflector was hotly debated but at that the time most of what would happen was mostly speculation. But I thought it was a smart move for any company that is in need of spreading its marketing message and corporate image as a vendor in the .NET space. Where else do you get to flash your corporate logo to hordes of .NET developers on a regular basis?  Exploiting that marketing with some goodwill of providing a free tool breeds positive feedback that hopefully has a good effect on the company’s visibility and the products it sells. Instead Red Gate seems to have taken exactly the opposite tack of corporate bullying to try to make a quick buck – and in the process ruined any community goodwill that might have come from providing a service community for free while still getting valuable marketing. What’s so puzzling about this boneheaded escapade is that the company doesn’t need to resort to underhanded tactics like what they are trying with Reflector 7. The tools the company makes are very good. I personally use SQL Compare, Sql Data Compare and ANTS Profiler on a regular basis and all of these tools are essential in my toolbox. They certainly work much better than the tools that are in the box with Visual Studio. Chances are that if Reflector 7 added useful features I would have been more than happy to shell out my $39 to upgrade when the time is right. It’s Expensive to give away stuff for Free At the same time, this episode shows some of the big problems that come with ‘free’ tools. A lot of organizations are realizing that giving stuff away for free is actually quite expensive and the pay back is often very intangible if any at all. Those that rely on donations or other voluntary compensation find that they amount contributed is absolutely miniscule as to not matter at all. Yet at the same time I bet most of those clamouring the loudest on that Red Gate Reflector feedback page that Reflector won’t be free anymore probably have NEVER made a donation to any open source project or free tool ever. The expectation of Free these days is just too great – which is a shame I think. There’s a lot to be said for paid software and having somebody to hold to responsible to because you gave them some money. There’s an incentive –> payback –> responsibility model that seems to be missing from free software (not all of it, but a lot of it). While there certainly are plenty of bad apples in paid software as well, money tends to be a good motivator for people to continue working and improving products. Reasons for giving away stuff are many but often it’s a naïve desire to share things when things are simple. At first it might be no problem to volunteer time and effort but as products mature the fun goes out of it, and as the reality of product maintenance kicks in developers want to get something back for the time and effort they’re putting in doing non-glamorous work. It’s then when products die or languish and this is painful for all to watch. For Red Gate however, I think there was always a pretty good payback from the Reflector acquisition in terms of marketing: Visibility and possible positioning of their products although they seemed to have mostly ignored that option. On the other hand they started this off pretty badly even 2 and a half years back when they aquired Reflector from Lutz with the same arrogant attitude that is evident in the latest episode. You really gotta wonder what folks are thinking in management – the sad part is from advance emails that were circulating, they were fully aware of the shit storm they were inciting with this and I suspect they are banking on the sheer numbers of .NET developers to still make them a tidy chunk of change from upgrades… Alternatives are coming For me personally the single license isn’t a problem, but I actually have a tool that I sell (an interop Web Service proxy generation tool) to customers and one of the things I recommend to use with has been Reflector to view assembly information and to find which Interop classes to instantiate from the non-.NET environment. It’s been nice to use Reflector for this with its small footprint and zero-configuration installation. But now with V7 becoming a paid tool that option is not going to be available anymore. Luckily it looks like the .NET community is jumping to it and trying to fill the void. Amidst the Red Gate outrage a new library called ILSpy has sprung up and providing at least some of the core functionality of Reflector with an open source library. It looks promising going forward and I suspect there will be a lot more support and interest to support this project now that Reflector has gone over to the ‘dark side’…© Rick Strahl, West Wind Technologies, 2005-2011

  • Industrialized SOA – topic of Business Technology Magazine

    - by JuergenKress
    Although it has become quieter around SOA, the concept is not buried at all. On the contrary, over the years it has reached a new maturity level. Hypes such as Cloud Computing and Big Data have pushed SOA out of the headlines; however "the new hypes have not replace service orientation, but built on it." The authors of this edition rank among to the SOA pioneers in Germany. They have gathered their collective knowledge for this issue and created a unique picture of the current state of SOA. According to them SOA has developed evolutionarily towards industrialization, towards a holistic platform - and thus towards a new Industrialized SOA. The issue 3.12 of the BT magazine (in Germany!) is available as an iPad App (http://it-republik.de/business-technology/bt-magazin-ipad-app), via mail (http://it-republik.de/business-technology/bt-magazin-ausgaben/Industrialized-SOA-000516.html) or at the kiosk!

  • Components needed for a VPN

    - by Anriëtte Combrink
    Hi there, first of all, I asked this question on SuperUser.com, but no one there could help me. Well, we eventually got our Mac Mini Server. We now want to set up a small Remote Access VPN using this Mac Mini Server. Firstly we are not sure of the components needed additionally to the server to setup this VPN. We currently have the following: 1 Mac Mini Server 1 Firewall Router (Billion 802.11g ADSL2+ router with VPN capabilities [it says so on the box]), we currently use this as our internet connection and resides X.X.0.1 on our network. 4Mbps ADSL connection (Should this line have VPN capability enabled by the service provider?) We are not sure what else needs to be included to enable our small VPN. Any advice would be really helpful?

  • Mysterious login attempts to windows server

    - by Jim Balo
    I have a Windows 2008R2 server that is reporting failed login attempts from a number of workstations on our network. Some event log details: Event ID 4625, Status: 0xc000006d, Sub Status: 0xc0000064 Security ID: NULL SID, Account Name: joedoe, Account Domain: Acme Workstation Name: WINXP1, Source Network Address: 192.168.1.23, Source Port: 1904 Logon Process: NtLmSsp, Authentication Package: NTLM, Logon Type: 3 (network) I believe this is coming from some netbios service or similar (maybe the file explorer), keeping an inventory of its network neighborhood and also trying to authenticate. Is there a way to turn this off without having to turn off file sharing all together? In other words, clients authenticating against file servers that they use is of course no problem, but I want to eliminate clients trying to authenticate to servers that they are not using and have no business with. The above example is only one of thousands of log alerts for similar failed network authentications. What can I do to clean this up / handle this? Thanks.

  • Replicate Oracle to MySQL

    - by Rosdi
    I am developing a web apps, this web application will be using MySQL. Now I need to replicate my client's Oracle database into MySQL, only a few tables will be involved.. a table can be up to 2-3 million rows. I only have SELECT privilege on this Oracle, so don't ask me to install any kind of service on the Oracle machine. I have complete control on the MySQL side however. The replication is only one way (Oracle to MySQL). I can write a simple script to truncate MySQL table and repopulate it every night but I think this is very inefficient, there must be a better way. Is there any free tools I can use? Expensive database replication system is definitely out of the question.

  • when to introduce an application services tier in an n-tier application

    - by user20358
    I am developing a web based application whose primary objective is to fetch data from the database, display it on the UI, take in user inputs and write them back to the database. The application is not going to be doing any industrial strength algorithm crunching, but will be receiving a very high number of hits at peak times (described below) which will be changing thru the day. The layers are your typical Presentation, Business, Data. The data layer is taken care of by the database server. The business layer will contain the DAL component to access the database server over tcp. The choices I have to separate these layers into tiers are: The presentation and business layers can be either kept on the same tier. The presentation layer on a separate tier by itself and the business layer on a separate tier by itself. In the case of choice 2, the business layer will be accessed by the presentation layer using a WCF service either over http or tcp. I don't see any heavy processing being done on the Business layer, so I am leaning towards option 1 above. I also feel for the same reason, adding a new tier will only introduce the network latency. However, in terms of scalability in case I need to scale up or scale out, which is a better way to go? This application will need to be able to support up to 6 million users an hour. There will be a reasonable amount of data in each user session, storing user's preferences and other details. I will be using page level caching as well.

  • Going Paperless

    - by Jesse
    One year ago I came to work for a company where the entire development team is 100% “remote”; we’re spread over 3 time zones and each of us works from home. This seems to be an increasingly popular way for people to work and there are many articles and blog posts out there enumerating the advantages and disadvantages of working this way. I had read a lot about telecommuting before accepting this job and felt as if I had a pretty decent idea of what I was getting into, but I’ve encountered a few things over the past year that I did not expect. Among the most surprising by-products of working from home for me has been a dramatic reduction in the amount of paper that I use on a weekly basis. Hoarding In The Workplace Prior to my current telecommute job I worked in what most would consider pretty traditional office environments. I sat in cubicles furnished with an enormous plastic(ish) modular desks, had a mediocre (at best) PC workstation, and had ready access to a seemingly endless supply of legal pads, pens, staplers and paper clips. The ready access to paper, countless conference room meetings, and abundance of available surface area on my desk and in drawers created a perfect storm for wasting paper. I brought a pad of paper with me to every meeting I ever attended, scrawled some brief notes, and then tore that sheet off to keep next to my keyboard to follow up on any needed action items. Once my immediate need for the notes was fulfilled, that sheet would get shuffled off into a corner of my desk or filed away in a drawer “just in case”. I would guess that for all of the notes that I ever filed away, I might have actually had to dig up and refer to 2% of them (and that’s probably being very generous). That said, on those rare occasions that I did have to dig something up from old notes, it was usually pretty important and I ended up being very glad that I saved them. It was only when I would leave a job or move desks that I would finally gather all those notes together and take them to shredding bin to be disposed of. When I left my last job the amount of paper I had accumulated over my three years there was absurd, and I knew coworkers who had substance-abuse caliber paper wasting addictions that made my bad habit look like nail-biting in comparison. A Product Of My Environment I always hated using all of this paper, but simply couldn’t bring myself to stop. It would look bad if I showed up to an important conference room meeting without a pad of paper. What if someone said something profound! Plus, everyone else always brought paper with them. If you saw someone walking down the hallway with a pad of paper in hand you knew they must be on their way to a conference room meeting. Some people even had fancy looking portfolio notebook sheaths that gave their legal pads all the prestige of a briefcase. No one ever worried about running out of fresh paper because there was an endless supply, and there certainly was no shortage of places to store and file used paper. In short, the traditional office was setup for using tons and tons of paper; it’s baked into the culture there. For that reason, it didn’t take long for me to kick the paper habit once I started working from home. In my home office, desk and drawer space are at a premium. I don’t have the budget (or the tolerance) for huge modular office furniture in my spare bedroom. I also no longer have access to a bottomless pit of office supplies stock piled in cabinets and closets. If I want to use some paper, I have to go out and buy it. Finally (and most importantly), all of the meetings that I have to attend these days are “virtual”. We use instant messaging, VOIP, video conferencing, and e-mail to communicate with each other. All I need to take notes during a meeting is my computer, which I happen to be sitting right in front of all day. I don’t have any hard numbers for this, but my gut feeling is that I actually take a lot more notes now than I ever did when I worked in an office. The big difference is I don’t have to use any paper to do so. This makes it far easier to keep important information safe and organized. The Right Tool For The Job When I first started working from home I tried to find a single application that would fill the gap left by the pen and paper that I always had at my desk when I worked in an office. Well, there are no silver bullets and I’ve evolved my approach over time to try and find the best tool for the job at hand. Here’s a quick summary of how I take notes and keep everything organized. Notepad++ – This is the first application I turn to when I feel like there’s some bit of information that I need to write down and save. I use Launchy, so opening Notepad++ and creating a new file only takes a few keystrokes. If I find that the information I’m trying to get down requires a more sophisticated application I escalate as needed. The Desktop – By default, I save every file or other bit of information to the desktop. Anyone who has ever had to fix their parents computer before knows that this is a dangerous game (any file my mother has ever worked on is saved directly to the desktop and rarely moves anywhere else). I agree that storing things on the desktop isn’t a great long term approach to keeping organized, which is why I treat my desktop a bit like my e-mail inbox. I strive to keep both empty (or as close to empty as I possibly can). If something is on my desktop, it means that it’s something relevant to a task or project that I’m currently working on. About once a week I take things that I’m not longer working on and put them into my ‘Notes’ folder. The ‘Notes’ Folder – As I work on a task, I tend to accumulate multiple files associated with that task. For example, I might have a bit of SQL that I’m working on to gather data for a new report, a quick C# method that I came up with but am not yet ready to commit to source control, a bulleted list of to-do items in a .txt file, etc. If the desktop starts to get too cluttered, I create a new sub-folder in my ‘Notes’ folder. Each sub-folder’s name is the current date followed by a brief description of the task or project. Then all files related to that task or project go into that sub folder. By using the date as the first part of the folder name, these folders are automatically sorted in reverse chronological order. This means that things I worked on recently will generally be near the top of the list. Using the built-in Windows search functionality I now have a pretty quick and easy way to try and find something that I worked on a week ago or six months ago. Dropbox – Dropbox is a free service that lets you store up to 2GB of files “in the cloud” and have those files synced to all of the different computers that you use. My ‘Notes’ folder lives in Dropbox, meaning that it’s contents are constantly backed up and are always available to me regardless of which computer I’m using. They also have a pretty decent iPhone application that lets you browse and view all of the files that you have stored there. The free 2GB edition is probably enough for just storing notes, but I also pay $99/year for the 50GB storage upgrade and keep all of my music, e-books, pictures, and documents in Dropbox. It’s a fantastic service and I highly recommend it. Evernote – I use Evernote mostly to organize information that I access on a fairly regular basis. For example, my Evernote account has a running grocery shopping list, recipes that my wife and I use a lot, and contact information for people I contact infrequently enough that I don’t want to keep them in my phone. I know some people that keep nearly everything in Evernote, but there’s something about it that I find a bit clunky, so I tend to use it sparingly. Google Tasks – One of my biggest paper wasting habits was keeping a running task-list next to my computer at work. Every morning I would sit down, look at my task list, cross off what was done and add new tasks that I thought of during my morning commute. This usually resulted in having to re-copy the task list onto a fresh sheet of paper when I was done. I still keep a running task list at my desk, but I’ve started using Google Tasks instead. This is a dead-simple web-based application for quickly adding, deleting, and organizing tasks in a simple checklist style. You can quickly move tasks up and down on the list (which I use for prioritizing), and even create sub-tasks for breaking down larger tasks into smaller pieces. Balsamiq Mockups – This is a simple and lightweight tool for creating drawings of user interfaces. It’s great for sketching out a new feature, brainstorm the layout of a interface, or even draw up a quick sequence diagram. I’m terrible at drawing, so Balsamiq Mockups not only lets me create sketches that other people can actually understand, but it’s also handy because you can upload a sketch to a common location for other team members to access. I can honestly say that using these tools (and having limited resources at home) have lead me to cut my paper usage down to virtually none. If I ever were to return to a traditional office workplace (hopefully never!) I’d try to employ as many of these applications and techniques as I could to keep paper usage low. I feel far less cluttered and far better organized now.

  • How to skip pushing the default gateway via DHCP in OpenWRT?

    - by francadaval
    I have a router with OpenWRT that I want to resolve IP addressing with DHCP without setting a default gateway. I have added a DHCP-Option parameter with value 3,0.0.0.0 that is supposed to set the default gateway by DHCP. Instead, the router IP is defined as default gateway for DHCP connections. How can I set a null default gateway (0.0.0.0) for connections configuration by DHCP? As said in a comment: I want this router to service a VirtualBox network that doesn't set a default gateway via DHCP.

  • What's the point of Netgear's WNHDB3004 "3DHD WIRELESS HOME THEATER NETWORKING KIT"

    - by badp
    Here's a crude representation of what I've got at home: floor 2 INTERNETS ---- MODEM/ROUTER ---- MY COMPUTER | floor 1 WIFI REPEATER ---- stuff | floor 0 more stuff TELEVISION Now, as part of our sat tv subscription we can get an additional service if we connect our decoder (located by TELEVISION obviously) to the internet. What they suggest is buying a Netgear 3DHD WIRELESS HOME THEATER NETWORKING KIT holy shit isn't my bullshit-o-meter flying high right now from the general buzzwordyness of this thing. What does this thing actually do that our existing wireless-enabled routers don't do? What's the point of having a third wifi router in the same house, this time only for one television? If I do decide to plunge €99 for this, should I connect it to the wifi repeater (which does not provide AAA quality internet, at least for all gaming purposes) or to my modem/router (risking issues with low signal?).

  • Weblogic 10.3.4 (PS3) nodemanager wont start?

    - by angelo.santagata
    Hi all, well Im back from Australia and one of the things which happened was Oracle announced the PS3 release of oracles SOA & Webcenter products have been released. Now I normally use pre-installed images but I always like to install the products at least once that way I get to see its installation caveats.. Here’s one. Installation on Windows 7 64bit, 64bit JVM, generic weblogic Server installer. All worked fine, EXCEPT I cant start the node manager, I get the following error <08-Feb-2011 17:16:48> <INFO> <Loading domains file: D:\products\wls1034\WLSERV~1.3\common\NODEMA~1\nodemanager.domains> <08-Feb-2011 17:16:48> <SEVERE> <Fatal error in node manager server> weblogic.nodemanager.common.ConfigException: Native version is enabled but nodemanager native library could not be loaded     at weblogic.nodemanager.server.NMServerConfig.initProcessControl(NMServerConfig.java:249)     at weblogic.nodemanager.server.NMServerConfig.<init>(NMServerConfig.java:190)     at weblogic.nodemanager.server.NMServer.init(NMServer.java:182)     at weblogic.nodemanager.server.NMServer.<init>(NMServer.java:148)     at weblogic.nodemanager.server.NMServer.main(NMServer.java:390)     at weblogic.NodeManager.main(NodeManager.java:31) Caused by: java.lang.UnsatisfiedLinkError: D:\products\wls1034\wlserver_10.3\server\native\win\32\nodemanager.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform     at java.lang.ClassLoader$NativeLibrary.load(Native Method)     at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1803)     at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1728)     at java.lang.Runtime.loadLibrary0(Runtime.java:823)     at java.lang.System.loadLibrary(System.java:1028)     at weblogic.nodemanager.util.WindowsProcessControl.<init>(WindowsProcessControl.java:17)     at weblogic.nodemanager.util.ProcessControlFactory.getProcessControl(ProcessControlFactory.java:24)     at weblogic.nodemanager.server.NMServerConfig.initProcessControl(NMServerConfig.java:247)     ... 5 more Ok it appears that the node manager has gotten confused and thinks this is a 32bit install of Weblogic Server whereas it is the 64bit install.. Might have been something I did, or didnt do, on installation (e.g. –d64 on the jvm command line), however the workaround is pretty easy. 1. Create a file called nodemanager.properties in %WL_HOME%\common\nodemanager on my machine it was D:\products\wls1034\wlserver_10.3\common\nodemanager 2. Add the following line to it NativeVersionEnabled=false 3. And start it up!, this will force it not to use .DLL files and use emulation/non native methods instead..

  • Unused Indexes Gotcha

    - by DavidWimbush
    I'm currently looking into dropping unused indexes to reduce unnecessary overhead and I came across a very good point in the excellent SQL Server MVP Deep Dives book that I haven't seen highlighted anywhere else. I was thinking it was simply a case of dropping indexes that didn't show as being used in DMV sys.dm_db_index_usage_stats (assuming a solid representative workload had been run since the last service start). But Rob Farley points out that the DMV only shows indexes whose pages have been read or updated. An index that isn't listed in the DMV might still be useful by providing metadata to the Query Optimizer and thus streamlining query plans. For example, if you have a query like this: select  au.author_name         , count(*) as books from    books b         inner join authors au on au.author_id = b.author_id group by au.author_name If you have a unique index on authors.author_name the Query Optimizer will realise that each author_id will have a different author_name so it can produce a plan that just counts the books by author_id and then adds the author name to each row in that small table. If you delete that index the query will have to join all the books with their authors and then apply the GROUP BY - a much more expensive query. So be cautious about dropping apparently unused unique indexes.

  • Cannot FTP without simultaneous SSH connection?

    - by Lucas
    I'm trying to set up an old box as a backup server (running 10.04.4 LTS). I intend to use 3rd party software on my PC to periodically connect to my server via FTP(S) and to mirror certain files. For some reason, all FTP connection attempts fail UNLESS I'm simultaneously connected via SSH. For example, if I use putty to test the connection to port 21, the system hangs and times out. I get: 220 Connected to LeServer USER lucas 331 Please specify the password. PASS [password] <cursor> However, when I'm simultaneously logged in (in another session) everything works: 220 Connected to LeServer USER lucas 331 Please specify the password. PASS [password] 230 Login successful. Basically, this means that my software will never be able to connect on its own, as intended. I know that the correct port is open because it works (sometimes) and nmap gives me: Starting Nmap 5.00 ( http://nmap.org ) at 2012-03-20 16:15 CDT Interesting ports on xx.xxx.xx.x: Not shown: 995 closed ports PORT STATE SERVICE 21/tcp open ftp 22/tcp open ssh 53/tcp open domain 139/tcp open netbios-ssn 445/tcp open microsoft-ds Nmap done: 1 IP address (1 host up) scanned in 0.15 seconds My only hypothesis is that this has something to do with iptables. Maybe it's allowing only established connections? I don't think that's how I set it up, but maybe? Here's my iptables rules for INPUT: lucas@rearden:~$ sudo iptables -L INPUT Chain INPUT (policy DROP) target prot opt source destination fail2ban-ssh tcp -- anywhere anywhere multiport dports ssh ufw-before-logging-input all -- anywhere anywhere ufw-before-input all -- anywhere anywhere ufw-after-input all -- anywhere anywhere ufw-after-logging-input all -- anywhere anywhere ufw-reject-input all -- anywhere anywhere ufw-track-input all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere tcp dpt:ftp I'm using vsftpd. Any thoughts/resources on how I could fix this? L

  • Slower site with the *same* configuration than a mirror copy…?

    - by Rosamunda Rosamunda
    I´ve got this Drupal site (ligadelconsorcista.org) that I have to move it from one server to another. The reason was that my older host even when it was pretty decent, it started a couple of months now to have many short downtimes, wich drove me crazy. The thing is that I´ve made a sort of mirror copy of the site: I´ve copied all the files exactly the same, and after that I´ve imported the database. The problem is that the new site connects much slower than my old hosting! (the new one is mediatemple) I´ve contacted their support and they tell me that there are several factors that can contribute to that... but that has nothing to do with their hosting service. The thing is that I don´t even know where to start looking for the problem. Notes: The new configuration is the same that the one I had with the older hosting account. Today I´ve set an account with cloudflare´s CDN to try to solve the problem. Even if the CDN is configured ok (I´ve asked their help desk) it won´t add any performance improvement. Any clues of what may I do about this? Thanks!!

  • Using JuJu with private Openstack cloud deployment?

    - by user76054
    I'm seeing a number of problems trying to use JuJu with our internally deployed Openstack cloud. Most of this appears to be centered around DNS host resolution as well as the need to deal with our company's internal HTTP proxies. Our Openstack deployment relies upon an unroutable 172.16.0.0/12 block of addresses for VLAN allocation to each project (tenant) hosted on our internal cloud. User's have the option of assigning one or more floating addresses to instances, allocated from a block of routable addresses on our internal companies LAN. Currently, Openstack doesn't register instance names with anything other than the DNSMASQ service running on the cloud controller. As such, there's no way to resolve this address through our internal DNS hierarchy (this issue has already been reported as Bug #945505). As such, even though I can bootstrap my JuJu server node, I can't connect to it with the JuJu client, since it can't resolve the local (private) network name. I am able to ssh to the node, once I've assigned it an internally routable (i.e. floating) address. Which leads to the next issue. Next, to install software on an instance running in our cloud, it must have our internal proxy address defined - either in the apt.conf file or via environment variables. Unfortunately, when bootstrapping the server node, there's no provision to pass this info into a instance via JuJu environment.yaml file (if this is even the best way to handle this issue). As a result, the bootstrap node is unable to install the required packages. I'm assuming (dangerous, I know) that the way that I've deployed Openstack in our internal environment is probably not unique. Has anyone else encountered these issues? And more importantly, are work arounds available? Regards, Ross
