  • Windows 7 Virtual PC - &ldquo;RPC server unavailable&rdquo;

    - by Kelly Jones
    I use Windows 7 Virtual PC on my current project and I often bring home the files, so I can work some in the evenings.  Since my VHDs are large, I’ll only copy the undo disks, saved state, and virtual machine config files from my external drive.  I copy them to a small portable drive and once I get home, I’ll copy them to a large external drive. I’ve done this for over a year, but recently I started getting an error when I tried to start the VPC after the copying was finished.  It would open the initial window with the progress bar, but eventually the bar would stop, turn red, and then the error “RPC server unavailable” would appear.  When I first started seeing these, I’d try again, but no luck. After some testing, it turns out that my small portable drive is apparently going bad, so it was corrupting the files.  Lucky for me, that I never overwrote my good copies with corrupted copies, at least not at both the office and at home.

  • Rsyslog problem after ubuntu upgrade 10.4 to 12.4

    - by Oxymoron
    I was using Ubuntu 10.4 until last week for storing the log informations of a external device with rsyslog. After upgrading to ubuntu 12.4 the logging of TCP doesn't works anymore. (There are just no pakets visible - not even with tcpdump - aold ubuntu machine still sees the pakets.) UDP works with the identical configuration on the ubuntu machine and a "use UDP" on the external device. Are there any changes in rsyslog, that could explain this? My rsyslog.conf file looks like this (with more comments): $ModLoad imuxsock # provides support for local system logging $ModLoad imklog # provides kernel logging support (previously done by rklogd) #$ModLoad immark # provides --MARK-- message capability $KLogPath /proc/kmsg # provides UDP syslog reception $ModLoad imudp $UDPServerRun 514 # provides TCP syslog reception $ModLoad imtcp $InputTCPServerRun 514 ########################### #### GLOBAL DIRECTIVES #### ########################### $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat # Set the default permissions for all log files. # $FileOwner syslog $FileGroup adm $FileCreateMode 0640 $DirCreateMode 0755 $Umask 0022 $PrivDropToUser syslog $PrivDropToGroup syslog if $fromhost-ip startswith '192.168.0.10' then /var/log/caliDevice.log & ~ # local/regular rules, like '.' /var/log/syslog.log $IncludeConfig /etc/rsyslog.d/*.conf

  • Minimum percentage of free physical memory that Linux require for optimal performance

    - by csoto
    Recently, we have been getting questions about this percentage of free physical memory that OS require for optimal performance, mainly applicable to physical compute nodes. Under normal conditions you may see that at the nodes without any application running the OS take (for example) between 24 and 25 GB of memory. The Linux system reports the free memory in a different way, and most of those 25gbs (of the example) are available for user processes. IE: Mem: 99191652k total, 23785732k used, 75405920k free, 173320k buffers The MOS Doc Id. 233753.1 - "Analyzing Data Provided by '/proc/meminfo'" - explains it (section 4 - "Final Remarks"): Free Memory and Used Memory Estimating the resource usage, especially the memory consumption of processes is by far more complicated than it looks like at a first glance. The philosophy is an unused resource is a wasted resource.The kernel therefore will use as much RAM as it can to cache information from your local and remote filesystems/disks. This builds up over time as reads and writes are done on the system trying to keep the data stored in RAM as relevant as possible to the processes that have been running on your system. If there is free RAM available, more caching will be performed and thus more memory 'consumed'. However this doesn't really count as resource usage, since this cached memory is available in case some other process needs it. The cache is reclaimed, not at the time of process exit (you might start up another process soon that needs the same data), but upon demand. That said, focusing more specifically on the percentage question, apart from this memory that OS takes, how much should be the minimum free memory that must be available every node so that they operate normally? The answer is: As a rule of thumb 80% memory utilization is a good threshold, anything bigger than that should be investigated and remedied.

  • How to integrate a PHP CMS with paypal so that only users who completed a payment can register and authenticate?

    - by ibiza
    I am currently using a PHP CMS - cmsmadesimple - in order to create a website where services will be sold. I intend to use Paypal 'Buy Now' buttons in order to offer a few packages that will be renewable every 1-month or every 3-months and that grant access to the secure content of the website for a given period of time. Everything is going well so far but I am somewhat at loss for the user registration process as I have a few constraints I would like to use and it would be nice to automate the process if possible. Here are the constraints : User should be able to register to my website and choose a password himself Only users that paid should be able to register Access permissions should be disabled automatically after the service period if the package is not renewed And here is the process which I am thinking of : User clicks 'buy' on my website User is redirected on Paypal and completes the payment The paypal email used to pay should be returned to my server and somehow stored If it is a new email, user needs to register to my website (else if it is a returning customer, the deactivation flag for payment stopped should be removed to give back access) If a user does not renew his subscription, there should be a deactivation flag automatically set to the email used in order to lock access until next payment. Ideally, no human intervention is needed. What is the best way to implement all this? I am a bit at loss. I found this article that explained a few things and even has a nice code snippet, except that I'm not sure where to plug it. Thanks all

  • Distributing a very simple application

    - by vanna
    I have a very simple working console application written in C++ linked with a light static library. It is just for testing purposes. Now that the coding part is done, I would like to know the process of actually distributing the program. I wrote a very basic CMakeLists.txt that create makefiles or VS projects to build the sources. I also have a program that calls the static library in order to make some google tests. To me, the distribution of this application goes like this : to developpers : the src directory with the CMakeLists.txt file (multi-platform distribution) with a README.txt and an INSTALL.txt to users : the executable and a README.txt on my git repo : everything mentionned above plus the sources for testing and the gtest external lib A this point : considering the complexity of my application, am I doing it right ? Is there any reference that would formalize this distribution process so I can get better and go further ? Say I would like to add dynamic libraries that can be updated, external libraries like boost : how should I package this to distribute it in a professionnal way ?

  • Using ASP.NET, Membership, and jQuery to Determine Username Availability

    Chances are, at some point you've tried creating a new user account on a website and were told that the username you selected was already taken. This is especially common on very large websites with millions of members, but can happen on smaller websites with common usernames, such as people's names or popular words or phrases in the lexicon of the online community that frequents the website. If the user registration process is short and sweet, most users won't balk when they are told their desired username has already been taken - they'll just try a new one. But if the user registration process is long, involving several questions and scrolling, it can be frustrating to complete the registration process only to be told you need to return to the top of the page to try a different username. Many websites use Ajax techniques to check whether a visitor's desired username is available as soon as they enter it (rather than waiting for them to submit the form). This article shows how to implement such a feature in an ASP.NET website using Membership and jQuery. This article includes a demo available for download that implements this behavior in an ASP.NET WebForms application that uses the CreateUserWizard control to register new users. However, the concepts in this article can be applied to ad-hoc user registration pages and ASP.NET MVC. Read on to learn more! Read More >

  • Why does plymouth start so late?

    - by Marky
    It appears that starting with 11.04 Plymouth starts so late in the boot process. Sometimes I only have a split second to see it before it transitions to the login screen. This is the same for 11.10. Compared to 10.04 and 10.10, Plymouth starts only a couple seconds or so after Grub and is very visible within the entire boot process. Is there something that can be done to have Plymouth run earlier? I have experienced this on 3 different machines and on 2 of these machines, I've been running Ubuntu since 10.04. So it's not just my notebook's hardware that is causing this. *One a side note, the boot process is one of the ugliest parts of modern Linux. Ubuntu is not excluded. After almost a decade, (I forget but was bootsplash the first?) this still has only been partly solved. For a couple of seconds ugly text is still seen when shutting down. On several ocassions, the same ugly text is seen when logging out of a session. It's never as smooth as you want it to be. Splash themes are great, don't get me wrong. It's just the transitions that are way off and you get glimpses of what's underneath. I'm used to this but for those new to Ubuntu and coming from Windows. It is a turn off.* pardon the rant. :)

  • How do I tell if my Windows server is swapping?

    - by churnd
    I'm using Process Explorer to monitor my windows server while it reconstructs some data. It's primarily a CPU intensive process, but I want to make sure it's not swapping. How can I tell if it is using Process Explorer? My initial guess is in the System Information window, it's Paging File Write Delta. Yes? No? I'm an idiot? *Screenshot is not of the server... just an example.

  • FTP won't open a connection to client

    - by Ben
    I am running Windows server 2008 on Ubuntu server 12.04.1 via devstack and I am trying to download a file from an ftp server using the windows command line ftp client. When I run the ftp get command I get the following error message: 500 I won't open a connection to 10.0.0.2 (only to XX.XX.XX.XX) 425 No data connection 10.0.0.2 is the internal IP address of the instance, whereas XX.XX.XX.XX is the external address. Is there anyway to make the ftp client use the external address for the data connection, or alternatively have the client establish the connection? Thanks

  • Has anyone got "Creative Soundblaster X-Fi Surround 5.1 Pro" - (usb Interface) installed?

    - by Vivek Sharma
    Has anyone tried this external usb sound blaster on ubuntu. http://us.store.creative.com/Sound-Blaster-XFi-Surround-5.1-Pro/M/B0044DEDCA.htm. I have bought M-Audio Bx5a deluxe Studio Monitors for my T61. I think the onboard Intel HD sound card will not do any justice to these speakers. So I am looking for an external sound interface. I particularly liked this one as it is not very expensive and it has a volume control (speaker lack a central-front volume knob). Has anyone been able to use this on ubuntu. Also, if anyone would like to recommend me another option?

  • List all BPM Processes for a user

    - by kasriniv
    Hello, Happy to start contributing to this blog..  The title of the blog is probably deceptively simple and warrants an elaboration. Customized BPM workspaces/user interfaces are a fairly common requirement. One of our marquee customers in the online stock trading business, envisioned this user interaction for their BPM application: User logs in to the internal portal Use will have list of roles which he is granted as a drop down list Once user selects the role, a list of processes which user is part of appear. Logged in user can be part of any swimlane role of the process This can be a fairly common/reasonable user-UI interaction pattern. 1. and 2. are easily achievable and hence the subject matter of this blog is the requirement in 3. Objective: Given a username and a role, list all the BPM processes that the user is part of, in any swimlane of any process. Here is quick overview of the major steps/logic in the code: Intialize workflow/BPM  context as usual Get a handle on InstanceQueryService(getInstanceQueryService), InstanceManagementService,        ProcessMetadataService and ProcessModelService List all Processes for that bpmcontext (listProcessMetadataSumary) and get Granted roles to that user For each of the processes [method  getAccessibleProcesss(ProcessMetadataSummary, Set)]for each of the lanes in the process, check if the role granted to the user, matches the roleName for that swimlane. If so, add to output. Notes: The usual caveats apply including BPM APIs are subject to change.  JDeveloper method introspection is your better friend than API documentation :-)... (I am going to try upload the source code  and if it doesnt work, will follow this blog up with the corresponding source code.) Hope this helps.  Ack: Yogesh K, BPM Dev team.

  • web based source control management software [closed]

    - by tom smith
    hi. not sure if this is the right place, but hopefully someone might have thoughts on a solution/vendor. Starting to spec out a project that will require multiple (50-100) developers to be able to manipulate source files/scripts for a large scale project. The idea is to be able to have each app go through a dev/review/test process, where the users can select (or be assigned) the role they're going to have for the given app. I'm looking for web-based, version control, issue tracking, user roles/access, workflow functionality, etc... Ideally, the process will also allow for the reviewed/valid app to then be exported to a separate system for testing on the test server/environment. This can be hosted on our servers, or we can do the colo process. I've checked out Alassian/Collabnet, but any thoughts you can provide would me appreciated as well. thanks

  • Managing PHP processes on Windows 7 (with WAMP)

    - by Andrea
    Is there a way to manage (especially list and kill) long-running PHP processes on a Windows 7 system set up with WAMP? Every once in a while, I'll accidentally throw an infinite loop into a PHP process and want to kill it. Right now, all I can think to do is to restart all my WAMP services but sometimes the PHP processes manage to survive right through the restart, i.e., I still see them outputting to logs even after WAMP's restarted. And if the process isn't logging, then I have no way at all to know when/if it's been killed. Not to mention, this will wipe out everything I'm doing with WAMP, not just a single process. I don't seem to see anything relevant in the Windows Task Manager, but maybe I'm missing something.

BigMachines’ CPQ Cloud accelerates the conversion of sales opportunities into revenue by automating the sales order process with guided selling, dynamic pricing, and an easy-to-use workflow approval process, accessible anywhere, on any device. Companies that use sales automation technology often rely on manual, cumbersome and disconnected processes to convert opportunities into orders. This creates errors, adds costs, delays revenue, and degrades the customer experience. BigMachines’ CPQ cloud extends sales automation to include the creation of an optimal quote, which enables sales personnel to easily configure and price complex products, select the best options, promotions and deal terms, and include up sell and renewals, all using automated workflows. In combination with Oracle’s enterprise-grade cloud solutions, including Marketing, Sales, Social, Commerce and Service Clouds, Oracle and BigMachines will create an end-to-end smarter selling cloud solution so sales personnel are more productive, customers are more satisfied, and companies grow revenue faster.

  • How to cleanup tmp folder safely on Linux

    - by Syncopated
    I use RAM for my tmpfs /tmp, 2GB, to be exact. Normally, this is enough but sometimes, processes create files in there and fail to cleanup after themselves. This can happen if they crash. I need to delete these orphaned tmp files or else future process will run out of space on /tmp. How can I safely garbage collect /tmp? Some people do it by checking last modification timestamp, but this approach is unsafe because there can be long-running processes that still need those files. A safer approach is to combine the last modification timestamp condition with the condition that no process has a file handle for the file. Is there a program/script/etc that embodies this approach or some other approach that is also safe? Incidentally, does Linux/Unix allow a mode of file opening with creation wherein the created file is deleted when the creating process terminates, even if it's from a crash?

  • Can't open Control Panel or IE

    - by Josh
    I have a XP computer where when ever I try to open Control Panel nothing happens, nothing flashes on the screen. Same thing with Internet Explorer. I've scanned the computer with Malwarebytes and Avast, Malwaresbytes found some Adware which it removed without problems. Avast found nothing. I looked at the running processes with Process Explorer, nothing malicious running. And looked at a Process Monitor output when I tried to run IE, nothing obviously wrong. The process just decides to exit. What can I try next? I would suspect corrupt IE install but Control Panel doesn't work either. UPDATE: Nether work in Safe Mode under the user account. (only 1 user on the computer) But in Safe Mode, under the built in Administrator account, they work. So what ever is broken, is only broken in the one account. Anything under the HKCU registry key that could break this?

  • Why are Back In Time snapshots so large?

    - by Chethan S.
    I just backed up the contents of my home partition onto my external hard drive using Back In Time. I browsed to the backed up contents in the external drive and under properties it showed me the size as 9.6 GB. As I read that in next snapshots I create, Back In Time does not backup everything but creates hard links for older contents and saves newer contents, I wanted to test it. So I copied two small files into my home partition and ran 'Take Snapshot' again. The operation completed within a minute - first it checked previous snapshot, assessed the changes, detected two new files and synced them. After this when I browsed to the backed up contents, I was surprised to see the newer and older backup taking up 9.6 GB each. Isn't this a waste of hard drive space? Or did I interpret something wrongly?

  • PHP processes run one at a time, always taking 100% of one core

    - by Derek Kurth
    We have seven websites written in PHP running on a Windows 2008 server with IIS 7.5. They are all very slow right now. When I look in Task Manager, I see around 10 php-cgi.exe processes, and they are all taking 0% of the CPU, except one, which is taking 25%. It's a quad-core server, so it's taking 100% of one core. If I watch for a few seconds, the process taking 25% will go to 0%, and a different php-cgi.exe process will jump to 25%. So all the php-cgi.exe processes are just lined up, waiting on a single core, and each process uses 100% of the processor when it can. Each of the 7 sites is in its own application pool in IIS, and we're using FastCGI. The PHP version is 5.3. Any ideas? Thanks!
