  • Why can't Ubuntu find an ext3 filesystem on my hard-drive?

    - by urig
    This question is related to this question: Not enough components to start the RAID array? I'm trying to retrieve data from a "Western Digital MyBook World Edition (white light)" NAS device. This is basically an embedded Linux box with a 1TB HDD in it formatted in ext3. It stopped booting one day for no apparent reason. I have extracted the HDD from the NAS device and installed it in a desktop machine running Ubuntu 10.10 in the hope of accessing the files on the drive. I have followed instructions in this forum post, intended to mount the drive through Terminal: http://mybookworld.wikidot.com/forum/t-90514/how-to-recover-data-from-wd-my-book-world-edition-nas-device#post-976452 I have identified the partition that I want to mount and recover files from as /dev/sd4 by running "fdisk -l" and getting this: Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0001cf00 Device Boot Start End Blocks Id System /dev/sdb1 5 248 1959930 fd Linux raid autodetect /dev/sdb2 249 280 257040 fd Linux raid autodetect /dev/sdb3 281 403 987997+ fd Linux raid autodetect /dev/sdb4 404 121601 973522935 fd Linux raid autodetect// When I try to mount using: "mount -t ext3 /dev/sdb4 /media/xyz" I get the following error: mount: wrong fs type, bad option, bad superblock on /dev/sdb4, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so And "dmesg | tail" shows me: [ 15.184757] [drm] Initialized nouveau 0.0.16 20090420 for 0000:01:00.0 on minor 0 [ 15.986859] [drm] nouveau 0000:01:00.0: Allocating FIFO number 1 [ 15.988379] [drm] nouveau 0000:01:00.0: nouveau_channel_alloc: initialised FIFO 1 [ 16.353379] EXT4-fs (sda5): re-mounted.

I guess that last line is the punch line :) Why can't it find the ext3 filesystem on my drive? What do I need to do to mount this partition and copy its contents? Does it have anything to do with the drive being part of a RAID Array (see question mentioned above)? Many thanks to any who can help.

  • Is is possible to get a patch included in the current release? If so, how?

    - by Oli
    So a while back I reported a bug in Compiz's Place Window plugin. It's a fairly major regression for people affected by it: mainly those using Gnome-Fallback, judging by the reports. A patch surfaced a short time later. I created a PPA for testing and everybody involved so far is reporting the issues are fixed. It even fixes another bug. I've done testing with a standard Unity desktop and can say (for my testing) no adverse effects were visible. I want to get this pushed to Ubuntu right now for two main reasons: I'm selfish. I don't want to need to update my PPA every time a new version of Compiz is pushed to 12.04. I don't want Ubuntu users seeing their windows flying around because of a silly little bug. I want this patch pushed to Ubuntu's version of Compiz as soon as possible, so we can mark these bugs fixed and move on with our lives. Whose leg do I have to hump to get this pulled into Ubuntu right now? I don't maintain this project and it's an upstream thing but it's fairly integral to Ubuntu. I could go to Compiz but I imagine that if they accept the patch, it'll be months (at least a release) before it's anywhere near Ubuntu. And when I do find the right person, how can I make the process as slick as possible for them? I want them to see my request, go "Yup, that all looks great, done" and that be it. I don't want seventeen rounds of emails addressing aspects of the patch. More importantly, I don't want to waste their time either. And what do I have to provide them? My packaging skills are... lamentable. This was my first attempt at patching a package for redistribution so I've probably made every single packaging error known to man. Will they be happy with the original patch (so they can apply it themselves) or should I repackage things so the diff/changelog is a little cleaner (it took me a few goes and the versioning is all over the place). Note: This question is about Compiz but I'd prefer if answers could address other styles of package too so we have an authoritative and comprehensive thread of how to get things fixed.

  • 3 Monitors, Ubuntu 12.04, Gnome 3, 2 nvidia cards, WITH xrandr or xinerama?

    - by Josh
    Ok. I have been banging my head against the wall for over a week now trying to get 3 monitors to work. I have: 1 - Nvidia 8600 GT 512MB PCIEx16 1 - Nvidia GT 240 1GB PCIEx16 They are not running in SLI (obviously). I have tried to use everything from tutorials to a few templates, all the way up to nvidia-settings, etc etc etc.. From what I hear, Xinerama doesnt like gnome 3 because of the compositing, although I have read a lot about using Xrandr instead, and getting the compositing working, but alas, I cannot. It always either crashes X and I have to replace the xorg.conf with my backup, or it defaults to the gnome-classic desktop, and on top of that, when it does default, it keeps adding more and more panels. Basically, I want to be able to use all 3 monitors (yes, just like in windows) to drag and drop from different windows. I have xorg-edit, but I am still not too sure on how to set this up? Is there any way to: A Get compositing working with 3 monitors, 2 nvidia cards, xinerama, and gnome 3? or BUse twinview with 3 monitors (I have heard it can be done by manually editing xorg.conf) or CSet up Xrandr to draw all 3 monitors with compositing. or DUse separate X for each monitor, and be able to use gnome with compositing, as well as drag between all 3 or EANYTHING. lol. I just want this to work. Any help you can provide would be greatly appreciated. BTW, I am running an ubuntu mini install with gnome. Everything works great but this. I can run it fine with 2 monitors and compositing, but not with 3. Also, what is the best GUI tool for editing xorg.conf? Im not finding anything that is up to date at all, and also is understandable by humans. haha. Im actually an engineer by trade, and have been working with computers a LONG time, but this xorg.conf stuff is really confusing the crap out of me. lol Thanks!

  • StringBuffer behavior in LWJGL

    - by Michael Oberlin
    Okay, I've been programming in Java for about ten years, but am entirely new to LWJGL. I have a specific problem whilst attempting to create a text console. I have built a class meant to abstract input polling to it, which (in theory) captures key presses from the Keyboard object and appends them to a StringBuilder/StringBuffer, then retrieves the completed string after receiving the ENTER key. The problem is, after I trigger the String return (currently with ESCAPE), and attempt to print it to System.out, I consistently get a blank line. I can get an appropriate string length, and I can even sample a single character out of it and get complete accuracy, but it never prints the actual string. I could swear that LWJGL slipped some kind of thread-safety trick in while I wasn't looking. Here's my code: static volatile StringBuffer command = new StringBuffer(); @Override public void chain(InputPoller poller) { this.chain = poller; } @Override public synchronized void poll() { //basic testing for modifier keys, to be used later on boolean shift = false, alt = false, control = false, superkey = false; if(Keyboard.isKeyDown(Keyboard.KEY_LSHIFT) || Keyboard.isKeyDown(Keyboard.KEY_RSHIFT)) shift = true; if(Keyboard.isKeyDown(Keyboard.KEY_LMENU) || Keyboard.isKeyDown(Keyboard.KEY_RMENU)) alt = true; if(Keyboard.isKeyDown(Keyboard.KEY_LCONTROL) || Keyboard.isKeyDown(Keyboard.KEY_RCONTROL)) control = true; if(Keyboard.isKeyDown(Keyboard.KEY_LMETA) || Keyboard.isKeyDown(Keyboard.KEY_RMETA)) superkey = true; while(Keyboard.next()) if(Keyboard.getEventKeyState()) { command.append(Keyboard.getEventCharacter()); } if (Framework.isConsoleEnabled() && Keyboard.isKeyDown(Keyboard.KEY_ESCAPE)) { System.out.println("Escape down"); System.out.println(command.length() + " characters polled"); //works System.out.println(command.toString().length()); //works System.out.println(command.toString().charAt(4)); //works System.out.println(command.toString().toCharArray()); //blank line! System.out.println(command.toString()); //blank line! Framework.disableConsole(); } //TODO: Add command construction and console management after that } } Maybe the answer's obvious and I'm just feeling tired, but I need to walk away from this for a while. If anyone sees the issue, please let me know. This machine is running the latest release of Java 7 on Ubuntu 12.04, Mate desktop environment. Many thanks.

  • What OpenGL version(s) to learn and/or use?

    - by zuko
    So, I'm new to OpenGL... I have general knowledge of game programming but little practical experience. I've been looking into various articles and books and trying to dive into OpenGL, but I've found the various versions and old vs new way of doing things confusing. I guess my first questions is does anyone know some figures about percentages of gamers that can run each version of OpenGL. What's the market share like? 2.x, 3.x, 4.x... I looked into the requirements for Half Life 2 since I know Valve updated it with OpenGL to run on Mac and I know they usually try to hit a very wide user-base, and they say a minimum of GeForce 8 Series. I looked at the 8800 GT on Nvidia's website and it listed support for OpenGL 2.1. Which, maybe I'm wrong, sounds ancient to me since there's already 4.x. I looked up a driver for 8800GT and it says it supports 4.2! A bit of a discrepancy there, lol. I've also read things like XP only supports up to a certain version, or OS X only supports 3.2, or all kinds of other things. Overall, I'm just confused as to how much support there is for various versions and what version to learn/use. I'm also looking for learning resources. My search results thus far have pointed me to the OpenGL SuperBible. The 4th edition has great reviews on Amazon, but it teaches 2.1. The 5th edition teaches 3.3 and there are a couple things in the reviews that mention the 4th edition is better and that the 5th edition doesn't properly teach the new features or something? Basically, even within learning material I'm seeing discrepancies and I just don't even know where to start. From what I understand, 3.x started a whole new way of doing things and I've read from various articles and reviews that you want to "stay away from deprecated features like glBegin(), glEnd()" yet a lot of books and tutorials I've seen use that method. I've seen people saying that, basically, the new way of doing stuff is more complicated yet the old way is bad . Just a side note, personally, I know I still have a lot to learn beforehand, but I'm interested in tessellation; so I guess that factors into it as well, because, as far as I understand that's only in 4.x? [just btw, my desktop supports 4.2]

  • password incorrect 3 times + suspected failed update

    - by Cheese
    I have been lurking your site for the past few hours, and have found myself in a bit of a pickle. Visiting my parents, I discover that neither computer, nor laptop work. Long story short, I've got the laptop working, but have completely fudged up the computer. I am a n00b, but I was at least willing to give it a go. The comp originally had ubuntu 11.10 installed, later updated to 12.04. We have cds for both. I do not understand what the initial problem was for my parents, but somehow when I turned on the computer, it worked for me. Soon after, I was nagged to install the latest updates. So, I spent the next half an hour wondering why the updates kept on asking for 11.04 cdroms, until I realised that you could turn off the cdrom necessity. After doing this via console, I installed some of the smaller updates, before being told to do a partial update. This failed a few times, and ended up freezing whilst reinstalling drivers. After a hard restart I continued to type whatever I could find on the forum into the console. At some point, the console started saying that I had 3 incorrect password inputs, and sudo commands stopped altogether. I found another thread discussing this; but people kept on suggesting changing passwords (which I did to no avail) or other things that made use of sudo (which I am locked out of, although I am technically the admin) I found myself somehow on the Ctrl+Alt+F1 console, and after being utterly confused (and Ctrl+AltF5 failing for me), another hard reset occurred. Somewhere along the way I created a USB start up for 14.04, (but this does not seem to work) Now I am left with an admin (and guest) account that log in but have blank screens (with only the desktop background showing) and I can't do anything in the console because I'm locked out. Interestingly, the console now says that I am running 14.04 although all updates said they had failed. Aside from the obvious lessons I have learnt (don't fiddle about in the console when you have no idea what you're doing "Dog wearing safety glasses "I have no idea what I am doing" GIF would be inserted here ) Is there any way I can redeem this almighty muck up? A million thanks for any help!

  • Boot error aftter clean Ubuntu 13.04 install: [Reboot and select proper boot device]

    - by IcarusNM
    I am having the same problem as this guy where a fresh Ubuntu install completes beautifully but will not boot. I get the ASUS (?) "Reboot and select proper boot device" error, first with Xubuntu 13.10 and after finally giving up there, and Xubuntu 13.4, I am back to regular Ubuntu 13.4. ASUS motherboard Z77, Intel chipset. Standard internal SATA 500GB HD. 64-bit. All-new hardware less than 3 months old. It was running Ubuntu 12.04LTC great until I tried this upgrade. I have re-installed from scratch every which way: with LVM, without LVM; with the default partitions, with my own partitions. With ext3 or ext4. Alongside; replace; upgrade. No difference. On the last two tries, I have booted afterward from the same USB stick, downloaded and run boot-repair, and now I guess I am off to the boot-repair support email with my URLs from that. It did all kinds of cool stuff but ultimately made no difference. I never got anything like this with Ubuntu 12.04. I've now probably re-installed Ubuntu 13.04 ten times slightly different ways. I finally found how to skip the language packs, so at least that sped things up! :) This starts from the ubuntu-13.04-desktop-amd64.iso and UNetbootin as suggested on the official instructions for USB thumb drive creation from OSX. That part all works fine (booting the USB on the PC and trying Ubuntu and/or installing from there on the PC HD.) I have no CD drive on this PC, but I suppose I could get one. I would rather find some Linux install that works from USB like I've always done. After running boot-repair twice, in the ASUS BIOS I now see three different UEFI boot options in the priority list, and they are all labeled exactly the same: ubuntu (P6: WDC WD5000AAKX-00U6AA0) Then there's a non-UEFI option: P6: WDC WD5000AAKX-00U6AA0 (476940MB) And a fifth option appeared after the first boot-repair: Windows Boot Manager (P6: WDC WD5000AAKX-00U6AA0) I have tried all 5 of these, and I get exactly the same error. I have never had Windows installed on this HD. ASUS is calling it Windows Boot Manaer but I presume that's a mistaken label for whatever boot-repair did. I can boot on USB and run GParted and it looks great. The partitions all look normal. I found another case of this online with no solution posted. I can't find much about it online. Needs a Master Boot Record wipe/redo?? I'm not sure how.

  • Cloud Computing Business Benefits

    - by workflowman
    If you have been living under a rock for the past year, you wouldn't have heard about cloud computing. Cloud computing is a loose term that describes anything that is hosted in data centers and accessed via the internet. It is normally associated with developers who draw clouds in diagrams indicating where services or how systems communicate with each other. Cloud computing also incorporates such well-known trends as Web 2.0 and Software as a Service (SaaS) and more recently Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). Its aim is to change the way we compute, moving from traditional desktop and on-premises servers to services and resources that are hosted in the cloud.  Benefits of Cloud Computing  There are clearly benefits in building applications using cloud computing, some of which are listed here:  Zero up- front investment:  Delivering a large-scale system costs a fortune in both time and money. Often IT departments are split into hardware/network and software services. The hardware team provisions servers and so forth under the requirements of the software team. Often the hardware team has a different budget that requires approval. Although hardware and software management are two separate disciplines, sometimes what happens is developers are given the task to estimate CPU cycles, disk space, and so forth, which ends up in underutilized servers.  Usage-based costing:  You pay for what you use, no more, no less, because you never actually own the server. This is similar to car leasing, where in the long run you get a new car every three years and maintenance is never a worry.  Potential for shrinking the processing time:  If processes are split over multiple machines, parallel processing is performed, which decreases processing time.  More office space:  Walk into most offices, and guaranteed you will find a medium- sized room dedicated to servers.  Efficient resource utilization:  The resource utilization is handed by a centralized cloud administrator who is in charge of deciding exactly the right amount of resources for a system. This takes the task away from local administrators, who have to regularly monitor these servers.  Just-in-time infrastructure:  If your system is a success and needs to scale to meet demand, this can cause further time delays or a slow- performing service. Cloud computing solves this because you can add more resources at any time.  Lower environmental impact:  If servers are centralized, potentially an environment initiative is more likely to succeed. As an example, if servers are placed in sunny or windy parts of the world, then why not use these resources to power those servers?  Lower costs:  Unfortunately, this is one point that administrators will not like. If you have people administrating your e-mail server and network along with support staff doing other cloud-based tasks, this workforce can be reduced. This saves costs, though it also reduces jobs.

  • Stumbling Through: Visual Studio 2010 (Part III)

  • Upgrading to 9.2 - Info You Can Use (part 2 - Get Hands On Experience)

    - by John Webb
    Our guest blogger, Rebekah Jackson, continues with a series of helpful hints on planning your upgrade to PeopleSoft 9.2. Get Hands-On Experience With a an Easy to Install Demo Image Once you have identified the features you believe can add value (see part 1 of this series here), we recommend that you use our Demo Images to quickly create a PeopleSoft environment where you can try out the new features. The Demo Images are virtual machines that run in VirtualBox.   They contain a fully functioning PeopleSoft environment, including the database, PeopleTools, and the application.  These images can be loaded onto nearly any sized machine that meets the specs outlined in the documentation, including a powerful desktop machine.     The image allows you to very quickly deploy a fully functioning PeopleSoft instance that you can use to explore new features and functions or run a conference room pilot. To take advantage these Demo Images: Go to the Demo Images Home Page (Doc id 1552548.1) on My Oracle Support. Use the " Demo Image Quick Start Guide" and additional documentation links on that page to download and install your desired Demo Image. New Demo Images are posted for each product area approximately every 10 weeks, available shortly after the corresponding patching image. When installed, use the Demo Image to explore the desired features and capabilities. Important Notes: - It is not required to use the Demo Images to evaluate features and functions – any 9.2 instance will support this. We recommend use of the Demo Images because the setup and configuration is dramatically faster than doing a traditional PeopleSoft install. - For those looking to explore new features and capabilities on PeopleSoft 9.1 releases, we have provided virtual machine images using the Oracle Virtual Machine technology. Details and links are available in Oracle’s PeopleSoft Virtualization Products page (Doc id 1538142.1). /* 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:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif"; mso-bidi-font-family:"Times New Roman";}

  • Multiple Problems Installing 12.04, now can't use Windows

    - by user87997
    First I tried using the 32-bit wubi.exe installer from the main Ubuntu website. It worked fine, dual booted with Windows 7 and all. I tried installing several applications and got errors. After searching for a little while for a fix, I found that someone else had solved the problem by uninstalling the 32-bit version and installing 64-bit Ubuntu. Apparently there is no wubi.exe installer for the 64-bit version, so I used LinuxLive to put the iso file onto a USB drive. I changed my the boot order in BIOS to check the USB first. It did, and I got into the Ubuntu installer just fine. Everything was working fine, but then I got an error that GRUB could not be installed. I chose "install manually later" or something like that. Immediately, the installer said it was done and ready for a reboot. At this point, my USB is still in the computer. The computer reboots...and it's back at the installer for the USB. I look up what's going on here, and someone says in a thread they solved it by selecting "Try Ubuntu" then installing it via a shortcut on the desktop. I assumed that Ubuntu simply hadn't installed and it would be safe to try again, so I did. It finished installing, this time I chose a different partition that wasn't being used. The thread also said to reinstall grub to the mounted drive, so I did that. Next I took out my USB and rebooted. I get stuck on the GRUB GNU loader, v.1.99 or something I believe it says at the top. I can't do anything, and it doesn't detect Windows 7 OR Ubuntu. When I check partitions, I have two 43 GB partitions that both have the same files in them (I'm assuming those are the two Ubuntu installations), and can only run Ubuntu off of my USB-- and can't run Windows 7 at all, however from within Ubuntu the windows 7 filesystem and files can still be seen. I have no idea what to do now. I used Ubuntu in the past (9.xx) and never had these sorts of problems! Please help. And sorry for the wall of text.

  • How to set up an rsync backup to Ubuntu securely?

    - by ws_e_c421
    I have been following various other tutorials and blog posts on setting up a Ubuntu machine as a backup "server" (I'll call it a server, but it's just running Ubuntu desktop) that I push new files to with rsync. Right now, I am able to connect to the server from my laptop using rsync and ssh with an RSA key that I created and no password prompt when my laptop is connected to my home router that the server is also connected to. I would like to be able to send files from my laptop when I am away from home. Some of the tutorials I have looked at had some brief suggestions about security, but they didn't focus on them. What do I need to do to let my laptop with send files to the server without making it too easy for someone else to hack into the server? Here is what I have done so far: Ran ssh-keygen and ssh-copy-id to create a key pair for my laptop and server. Created a script on the server to write its public ip address to a file, encrypt the file, and upload to an ftp server I have access to (I know I could sign up for a free dynamic DNS account for this part, but since I have the ftp account and don't really need to make the ip publicly accessible I thought this might be better). Here are the things I have seen suggested: Port forwarding: I know I need to assign the server a fixed ip address on the router and then tell the router to forward a port or ports to it. Should I just use port 22 or choose a random port and use that? Turn on the firewall (ufw). Will this do anything, or will my router already block everything except the port I want? Run fail2ban. Are all of those things worth doing? Should I do anything else? Could I set up the server to allow connections with the RSA key only (and not with a password), or will fail2ban provide enough protection against malicious connection attempts? Is it possible to limit the kinds of connections the server allows (e.g. only ssh)? I hope this isn't too many questions. I am pretty new to Ubuntu (but use the shell and bash scripts on OSX). I don't need to have the absolute most secure set up. I'd like something that is reasonably secure without being so complicated that it could easily break in a way that would be hard for me to fix.

  • database independent coding framework options?

    - by statirasystems
    Background: I have not programmed in a while besides doing VBA and a little VB.NET. So please forgive my language use. I'm green and have a head cold. I am reading all I can now, but I have no programming circles to draw from. The information I am providing is to help guide you to what I am looking for. I am not confident I can ask the question properly. Story: I have four different projects that I am starting. Obviously I won't be working on all at the same time however they each will have similar needs and be inter related. They are as follows: Desktop Environment/System User Interface - basically a product that runs on major computers via mono or .net that unifies the look and functions. In the context of the up coming question it would be able to directly access data of various types. It would work in tandum with my office suite, system manager, and network application framework. Office Suite - technically it would not be a suite since I will be doing it from one interfacel except for the Communications Application. As far as the question, it will need to be able to link to various data sources for storing files and using, manipulating, and presenting information. System Manager - an intellegent system to manage and administer the entire network and all equipment. As far as the question, needs to be able to access data for archiving and and for accessing it's own settings stored in various formats, sql or xml. Network Application Framework - A complete system that can be used for ERP, CRM, CMS, Errata, File Management, and so on. As to the question to be able to access it's own or interlink with existing applications. Requirement: C#, Simplifies and reduces coding, use the same code to access diffent databases(ie MySQL, MS SQL, ACCESS, XML, ...), Mono would be nice but not a must, Question: What librarys, frameworks, or other options would be able to help with this? Is there a good resource to guide me? I don't want arguing over what is best, just information to help me further understand and make an educated decision.

  • Why does my UIWebView not Allow User Interaction?

    - by thomasmcgee
    Hi, I'm new to these forums so I apologize for my noobieness. I did as thorough a search as I could, but I couldn't find anyone else with this issue, applogise if this has been covered elsewhere. I've created a very simple example of my problem. I'm sure I'm missing something but I can't for the life of me figure out what. I'm creating a UIWebView and adding it to a custom view controller that inherits from UIViewController. When the app loads in the iPad simulator, the uiwebview loads the desired page, but the UIWebView is entirely unresponsive. The webview does not pan or scroll and none of the in page links can be clicked. However, if you change the orientation of the webview suddleny everything works. Thanks in advance for your help!!

  • WebSphere Application Server EJB Optimization

    - by Chris Aldrich
    We are working on developing a Java EE based application. Our application is Java 1.5 compatible and will be deployed to WAS ND 6.1.0.21 with EBJ 3.0 and Web Services feature packs. The configuration is currently one cell with two clusters. Each cluster will have two nodes. Our application, or our system, as I should rather say, comes in two or three parts. Part 1: An ear deployed to one cluster that contains 3rd party vendor code combined with customization code. Their code is EJB 2.0 compliant and has a lot of Remote Home interfaces. Part 2: An ear deployed to the same cluster as the first ear. This ear contains EBJ 3's that make calls into the EJB 2's supplied by the vendor and the custom code. These EJB 3's are used by the JSF UI also packaged with the EAR, and some of them are also exposed as web services (JAX-WS 2.0 with SOAP 1.2 compliance) for other clients. Part 3: There may be other services that do not depend on our vendor/custom code app. These services will be EJB 3.0's and web services that are deployed to the other cluster. Per a recommendation from some IBM staff on site here, communication between nodes in a cluster can be EJB RMI. But if we are going across clusters and/or other cells, then the communication should be web services. That said, some of us are wondering about performance and optimizing communication for speed of our applications that will use our web services and EJB's. Right now most EJB's are exposed as remote. (and our vendor set theirs up that way, rather than also exposing local home interfaces). We are wondering if WAS does any optimizations between apps in the same node/cluster node space. If two apps are installed in the same area and they call each other via remote home interface, is WAS smart enough to make it a local home interface call? Are their other optimization techniques? Should we consider them? Should we not? What are the costs/benefits? Here is the question from one of our team members as sent in their email: The question is: Supposing we develop our EJBs as remote EJBs, where our UI controller code is talking to our EXT java services via EJB3...what are our options for performance optimization when both the EJB server and client are running in the same container? As one point of reference, google has given me some oooooold websphere performance tuning documentation from 2000 that explains a tuning configuration you can set to enable Call By Reference for EJB communication when they're in the same application server JVM. It states the following: Because EJBs are inherently location independent, they use a remote programming model. Method parameters and return values are serialized over RMI-IIOP and returned by value. This is the intrinsic RMI "Call By Value" model. WebSphere provides the "No Local Copies" performance optimization for running EJBs and clients (typically servlets) in the same application server JVM. The "No Local Copies" option uses "Call By Reference" and does not create local proxies for called objects when both the client and the remote object are in the same process. Depending on your workload, this can result in a significant overhead savings. Configure "No Local Copies" by adding the following two command line parameters to the application server JVM: * -Djavax.rmi.CORBA.UtilClass=com.ibm.CORBA.iiop.Util * -Dcom.ibm.CORBA.iiop.noLocalCopies=true CAUTION: The "No Local Copies" configuration option improves performance by changing "Call By Value" to "Call By Reference" for clients and EJBs in the same JVM. One side effect of this is that the Java object derived (non-primitive) method parameters can actually be changed by the called enterprise bean. Consider Figure 16a: Also, we will also be using Process Server 6.2 and WESB 6.2 as well in the future. Any ideas? recommendations? Thanks

  • How to cope with developing against a poor 3rd party API/application?

    - by wsanville
    I'm a web developer, and my organization has recently started to use a proprietary ASP.NET CMS for our web sites. I was excited to get started using the CMS, thinking it would bring a lot of value to our end users and be fun to work with, since my skills are a good match for the types of projects we're using it for. That was about a year ago. Since then, we've ran into all kinds of issues, from blatant bugs in the product, to nasty edge cases in the APIs, to extremely poor documentation for developers. On about a weekly basis, we are forced to pursue workarounds and rewrite some of the out of the box functionality, and even find some of the basic features unusable. In many cases, since this is a closed source application (and obfuscated of course), there's nothing we can do as developers to solve these issues. So my question is, how does one attempt to develop a good application in such a scenario? The application mostly works when using the the exact out of the box behavior, or using one of the company's starter sites. However, my attempts to use the underlying APIs to implement slightly different, yet reasonable behavior has proved to be extremely time consuming (not to mention just as buggy), given the lack of good information about the APIs. I've given this a lot of thought, and my conflicting viewpoints are the following: Strongly advise against any customization to the CMS, as development time will rise exponentially, or even have an extremely high chance of failing. While this is accurate, I do not want to give the impression that I am not willing to code my own solutions to problems and take the initiative to implement something difficult or complex. I don't want to be perceived as someone who is not motivated, lazy, or not knowledgeable to do anything complex, because this is simply not the case. I love coding my own solutions, trying new/difficult things, I just dislike the vendor app we're using. Continue on the path I'm on now, which is hacking my way past all issues I encounter and try my best to deliver an application that meets the needs and specs exactly. My goals are to make it as seamless and easy to use as possible to the end user, even when integrating the CMS with our other applications internally. The problem I'm finding with this approach is it is very time consuming. I open support cases with the vendor on a regular basis to solve issues and to gain knowledge of their APIs, but this is extremely time consuming, and in some cases it leads to dead ends. I post on the vendors forums on a regular basis but have become frustrated as most of my posts get 0 replies. So, what would you, a reasonable developer, do in this case? How can I make the best of the situation? And just for fun, here are some of the code smells and anti-patterns I've dealt with using the product (aside from their own code blatantly failing): Use of StringBuilder to concatenate a giant string that is hard coded and does not change. They use it to concatenate their Javascript and write it out into the body tags of their pages. Methods that accept object or Microsoft.VisualBasic.Collection as the parameters. In the case of the VB Collection, the data is not a list of any kind, it's used instead of making a class. Methods that return a Hashtable of VB Collections Method names of the form MethodName_v45, MethodName_v20, etc... Multiple classes with the same name in different namespaces with different functionality/behavior. Intellisense that reads "Note: this parameter is non functional" Complete lack of coding standards, API is filled with magic numbers and magic strings. Properties with a getter of type object that accepts totally different things, like enum or strings, and throw exceptions at runtime when you pass in something not supported. And much, much, more...
