  • Application to test a cluster/grid

    - by Mystic
    Is anyone aware of any application (computation + data) that I can download to test an in-house grid middleware that will run on a local cluster. I hope to compare the performance with other available grid systems.

  • Webserver optimization

    - by f-aminov
    Hi guys! I have a website hosted on a VPS (512Mb - minimum guranteed memory, 510Mhz proccessor, Debian 5.0 Lenny, Apache 2.2.9 with nginx 0.7.65 as a frontend to serve static content, MySQL 5.1.44, PHP 5.3.2 with APC caching). I'm a web developer, so I'm not very good at optimizing servers, but I've managed to install and setup all those neccessary components (LAMP, nginx, etc.). After that I decided to stress test my website (which uses Drupal 6.16 with caching and all possible optimization enabled) using a utility called "Webserver Stress Tool 7". And it seems to me that the results aren't any good - here is a graph (sorry, as a new user I'm not allowed to post images) As you can see the response time depending on amount of simultaneous users increases very quickly. With 10 simultaneous users the time is about 1000ms, with 100 simultaneous users it's about 15000ms (15s!). The question is do you think this is normal behavior for such a server or something is wrong with the settings and optimization? If you think something is wrong what particulary could be wrong? Any other suggestion how to speed this a little bit up?

  • Servers in DMZ will not communicate with each other

    - by Tukaro
    (Full disclosure: I rate barely above "noob" when it comes to networking.) My workplace recent got a new web server. Since we're nearing the end of an overhaul of our website, we're doing a slooooow migration between the old web server and the new one. The old webserver (we'll call it SERVOLD) is Windows Server 2008 with IIS 7. It does not have SQL Server installed. The new server (SERVNEW) is Windows Server 2008 R2, IIS 7.5, with the same version of SQL Server installed. Both are located in the DMZ for our network, and both have their own outward-facing IP address (.3 and .4, respectively). Each server can communicate fine with computers within the domain (not in the DMZ), and those same computers have no trouble communicating with either server. Both servers are also accessible from the internet just fine. However, no matter what, these two servers just refuse to recognize each other. They have the same Workgroup name listed (WORKGROUP), and I thought that would be enough for them to recognize each other. What needs to happen such that I can get these two servers to communicate with each other? We want to do a gradual roll-over to the new website (new one uses ASP.NET, old one uses CFMX), so being able to use one database between both servers is a necessity. Thanks!

  • Windows server 2008 R2 error :The page file is to small to complete the action

    - by kishore
    I have a windows server 2008 R2 standard edition. The system suddenly stopped accepting remote desktop connections. When I tried to connect directly to the console, I am unable to start any applications. I got errors "The page file is to small to complete the action". Under takmanager in performance the system shows "Commit(GB) 127/127". What does this imply? The system has 32 GB ram, 5 raid disks each 150 Gb

  • Help: Setup Outgoing Mail Server Only for Multiple Domains Using Postfix?

    - by user57697
    I want an outgoing mail server ONLY for multiple domains. I plan to use Postfix as that seems to be the easiest to setup being very new to Ubuntu/Linux. The setup I plan to have are as follows: I want to use virtual domain with postfix i.e. my multiple websites must be able to send an email from each their respective domains i.e. [email protected] is sent from my domain1.com website and [email protected] is sent from domain2.com website This is an outgoing mail server only i.e. I don't want any returned (or otherwise) email sent to my postfix server. Incoming mail is handled by Google Apps/Gmail and is already setup. I already set my SPF recording to designate my mx records and postfix server ip as valid email servers i.e. "v=spf1 mx include:mydomain.com -all" How can I achieve this? I'm frankly a little confused, so some help would be appreciated. I attempted to follow these guides here, but it doesn't seem right (and it isn't clear what all the settings mean): How to configure Postfix virtual domains http://www.sysdesign.ca/guides/postfix_virtual.html Postfix Installation *.slicehost.com/2008/7/29/postfix-installation Basic Postfix settings (main.cf) *.slicehost.com/2008/7/31/postfix-basic-settings-in-main-cf I can only post one link, but those articles above can be found by replacing * with articles in the hyperlink.

  • Can an SATA hard drive image be restored onto an SSD?

    - by Bryan Parker
    I'm currently using an SATA hard drive on my primary dev machine, but planning to upgrade to an SSD at some point soon. I use TrueImage on a regular basis to make backups, and to upgrade my harddrive without reinstalling everything. Will I be able to restore and boot onto an SSD? Will there be a performance hit or other issues to watch out for?

  • MacBook Pro - Aquamacs - spell check

    - by peggy Li
    I have tried to use spell check for aquamac. I highlighted a region of the text. Then clicked Edit, then spell check region. I got the error message: Error : No word lists can be found for the language "en_US". Then I went to the website to download the following dictionaries: CocoAspell : I just clicked the download button. It was reported that the download was successful. However, when I tested it and highlighted a text region and clicked spell check. The same error message came out. Do I need to pull the downloaded .pkg to a certain place, such as the application folder, before I opened the .pkg? Or what else do I need to do make it work? I also downloaded the base package Aspell (for Intel) and the pre-built dictionaries as (as the instruction of the website), just the same way as point 1. I still got the same error message. Again, Do I need to pull the downloaded .pkg to a certain place, such as the application folder, before I opened the .pkg? Or what else do I need to do make it work? I would be greatly appreciated if someone could give me some help? Peggy Li

  • compile Passenger statically into Apache httpd?

    - by Oleg
    I prefer to disable httpd dynamic module loading on my production server. I've been using mod_jk linked statically into httpd for quite a long time and it proved to be stable. Now I would like to add Ruby Passenger (mod_rails/mod_rack) to my httpd. I wonder if it is possible to link it statically into Apache httpd the same way too? (without producing a huge httpd) If it is, are there any potential pitfalls, safety or performance concerns having both mod_jk and mod_rails within the same executable? Thanks

  • CPU/Mem/Disk utilization (average) after process has completed

    - by BassKozz
    Ubuntu Server 9.10 So there is the time command which will show you the time it took for a specific process/command to run after the command has completed. For example: :~$ time ls real 0m0.020s user 0m0.000s sys 0m0.000s I'd like to also collect the average CPU usage, Memory, and Disk (i/o) utilization after the process has completed using time (or another command if necessary). How can I accomplish this? Mainly I am using this to benchmark MySQL import performance using different innodb_buffer_pool_size settings.

  • Optimal setup for ASUS P6X58D Premium BIOS (no OC)?

    - by rumtscho
    Normally, I'd trust the mainboard manufacturer to choose the best options as defaults. But I had trouble with the board, because even with Quick Boot enabled, it booted twice as slowly as a Pentium 4 Celeron. Then I changed lots of options at once (most of them weren't explained in the manual, just mentioned with a single sentence) and the boot time is only marginally worse than the Pentium 4 (54 sec against 46 sec from button to pw entering screen). Now I don't know if I have turned something off which should have stayed on. I guess I even won't be able to boot from a CD now, because even though it is present in the boot sequence, I took off a timeout I think it needs to check whether there is a disk in the drive. The second reason is that I don't have an internal HDD, only a SSD. I forgot my sources blush but I am under the impression that today's BIOS and OS options are geared toward booting from a HDD, which is often less than optimal when one boots from a SSD, especially when there are functions which cause avoidable writing cycles, as a SSD wears out after too many writing cycles. Most of the things I've read concern the OS, but there are some BIOS-relevant options too. I am especially confused about the disk mode. The board supports AHCI, IDE-simulation and RAID, but of the different articles I've read, there is a proponent for each and no clear arguments for any. So can one tell me which options are important in general and which are important for a SSD-only system? I don't want to overclock the CPU, so you don't have to say anything about this (yes I know the board is meant for OC:)). I am thinking of overclocking the RAM, since they sold me 1600er heatsinked modules which are running at 1066 now, but I'm not sure yet about that. The rest of the system: i7-930, Intel X25-m G2, 6 GB RAM, GTS 250, some no-name Blue-ray ROM. 2 external HDDs over USB 2.0. Lots of other USB-connected hardware (12 devices I think), no SATA 3 drives (will disabling the controller have an impact on performance?), no LAN, only WiFi. Lucid Lynx 64 bit, no dual boot, no virtual installations. The main uses of the system are: managing and playing/showing all the media stored on the external disks, lots of image manipulation, some video editing, a bit of (non-demanding) gaming, rarely development. Lots of Internet surfing too, but this shouldn't have much impact on performance.

  • Java applet class never found

    - by Andrew
    I am having a problem with the java plugins of all three major browsers: chromium, firefox and Internet Explorer. The issue is that applets will always fail to load and yield errors no matter what website or what applet I am trying to use. I can not see any of the example applets on oracle's website; I can not launch the minecraft browser applet; nor can I launch any applet across the web using any browser. I always receive a "class not found:AppletClassHere.class" error. I know that my browser plugin must be working correctly because I can launch the Cisco Nac applet each time I connect to my network and I can launch my own simple applets offline. I am connecting to the internet through a vpn in case that is important. It also seems like a lot of other people I know are having this issue. Re-installing the plugin does not appear to fix the issue. I am asking this question to find out the cause of this problem, and any possible solutions. Thank you.

  • Developer Notebook i5 or i7

    - by Cas Sakal
    I could not decide on which configuration below gives better performance for developers on a notebook(running VS.NET, SQL Server, no gaming); (A) i5 540M + SSD (Intel) or (B) i7 720M + 7200 RPM HDD (Western Digital) Since these two configurations(A, B) costs nearly same $ for me, I would like to buy the fastest one for my job environment. Please do not comment just buy this or that, if you can give an inference about your choice I would be appreciated. Thank you, cas

  • Setting up DNS using VirtualMin/WebMin

    - by Nyxynyx
    I am moving from a cPanel server to one where I've installed VirtualMin. The LAMP stack and the website files have been setup properly and I can access the website by its IP address. Problem: Now its time to point my domain mydomain.com to my new server. After reading many sites describing setting up bind and master zones, I am pretty confused as to what to do, especially coming from a cPanel server where its really simple to set this up. Attempt Tried to register my nameservers ns1.mydomain.com and ns2.mydomain.com at my domain registrar, but I am missing the IPs I need to point these nameservers to. Should I set ns1.mydomain.com to the IP addres of my web server, and not register ns2.mydomain.com? When specifying the DNS for mydomain.com, the first one I've set it to ns1.apadment.com. On the manager/admin page of my webhost provider, I am given the option to create a secondary slave DNS, which I assigned to the IP address of my server. Though I am not sure how the slave DNS will copy the info from my web server? I have assigned this secondary DNS ns.hostprovider.com as the second DNS for mydomain.com I tried creating a Virtual Server under Virtualmin, but it seems to mess up Apache's DocumentRoot for the site by creating and enabling a new vhost file that ends with .conf. I edited the .conf file to point DocumentRoot back to where its supposed to be /var/www/mydomain instead of /user/mydomain.com I believe the next step is to setup the zone. Virtualmin has already created a Master Zone with 8 different addresses (www.mydomain.com, ftp.mydomain.com...). Under Nameservers, there are already 2 records. One is the hostname (random name given by hostprovider, ns12345.ip123-123.net), the other is the secondary slave DNS provided by the host provider. Does having BIND running on my web server makes the server the master DNS? Thank you!

  • How to copy a bunch of pages? Is there a 3rd party tool?

    - by unknown (yahoo)
    (I asked the following question at the DNN forum, and also at snowcovered. Nobody knew of such an obvious time-saver being for sale. I'm posting here in case anybody knows of a freeware module that might do this.) By "groups of dnn pages", I mean pages that form a hierarchy (not necessary a hierarchy that is headed with a page at the same level as the Home page.) I know that I can copy web pages, one by one, using the admin login via the web-based dnn interface. But, I'd prefer a script or wizard, of some sort (that runs scripts behind the scenes) that can allow me to 1) specify a web page that I want to copy (along with the hierarchy of pages under it) 2) specify the names and titles of the new top-level pages 3) specify whether the contained modules of the top-level page that I want to copy is to be : ( ) New ( ) Copy ( ) Reference (as in the web-based interface) 4) repeat 3) for each of the source pages in the hierarchy that I want to copy You might say that I am looking to do something similar to creating a portal web site based on a template, except that it's not an entirely new website - instead it's a section of the current web site. I might want to do this because I have an organization which is broken into chapters, and I want each chapter to have, say, it's own General Information page (which acts like it's home page), and underneath that, in it's hierarchy, a Contact Info page and an Events page. so: Home Page   General Information Page     Contact Info     Events -- Home Page   General Information Page     Contact Info     Events   General Information Page Kiwanis - Bloomfield     Contact Info     Events   General Information Page Kiwanis - Dayton     Contact Info     Events If I have 200 chapters, I certainly don't want to copy those 3 web pages using the web based interface, as that would take a long time. (And imagine if each chapter's new sub-website had 30 pages!) I just want to specify the parameters of a copy process, then press a button, and let the system do the rest.

  • Websites down EC2 inaccessible via SSH CPU utilisation 100% last few hours - what should I do?

    - by fuzzybee
    I have multiple websites hosted on 1 single EC2 instance. 1 website "abc" were down for a few hours, sometimes threw database connection error and sometimes just took too long to respond. 1 website "def" were incredibly slow but still up and running the rest of the websites had the same symptoms has "abc" I can afford 15 min or less down time for "def". Should I then (in AWS console) reboot my instance or create an AMI image from my instance and launch it and associate my elastic IP to the new instance or "launch more like this" Background on what may have happened to my ec2 The last time I made changes for 21 hours ago. A cronjob to create snapshots ran around 19 hours ago and it has been running for a long time. Google Analytics shows traffic to my websites such as kidlander.sg has been nothing exceptional. Is there any other actions I should take or better options I could have? (I have already contacted AWS support but their turnaround is 12 hours so I appreciate all the help I could get) Update I got everything back up and running and CPU utilisation back to normal, around 30%. There is 1 difference between "def" and "abc" as well as my other websites "def"'s database is hosted on RDS "abc"'s database is hosted on an EC2 instance (different from my web server instance) configured by myself Nevertheless, I checked the EC2 instance I'm using as MySQL server yesterday and it was absolutely fine during the incident low CPU ultilisation I could log in using linux command line

  • Outlook 2007, how to stop replies from being sent if they meet criteria

    - by CChriss
    I have my college's email account auto-forwarded (they don't offer pop3 or imap) to my main gmail account so I don't have to go to their website to check for mail. That gmail account, and others, use pop3 down to my Outlook 2007. In my Outlook, I have a rule that puts mail sent to my @college address into a folder named Collegemail. Since the college email system lacks pop3 or imap, I have to go to their site to send a reply, so that the reply will be sent from my @college email address. The problem is that I cannot seem to get into the habit of going to my college's website to reply to those emails, so quite often I reply to them while in Outlook, which means my replies are sent "from" my main gmail address. How can I set up Outlook to either 1) disable replying to emails in the Collegemail folder or to emails where my college email address is in the original To: line, or else 2) set it to send those replies from a non-functional dummy account. The dummy account would be unable to send the email so the email would be stuck in the Outbox. (I already have the non-functional dummy account set up as Outlook's "Default" account. When I compose a new mail I have to deliberately pick one of my good accounts to send the new mail with, or else Outlook uses the default dummy account and the email stays in the Outbox with a Send error.) Thanks. Update: Anybody? Please help.

  • Linux Mplayer Instead of flash any distro/browser

    - by data_jepp
    The thing is that flash sucks for linux on 64-bit, performance vice. Due to this I actually download every clip to a temp folder and play the file while it's being downloaded with mplayer. This works really nice. Flash is not to play a video. Does there exist a plugin for this for any browser? I tried google, but I can't find the right words to search for.

  • JBOSS App Server vs. Glassfish

    - by codingbear
    I'm quite newbie on Glassfish. What are some differences between JBoss and Glassfish? Why would you chooose one over the other. I'm trying to read up on Glassfish, but it is really hard to pinpoint things that I may need before I start installing and trying to deploy some applications on it. UPDATE It would be good if any additional information on JBoss and Glassfish comparison is provided (e.g. technologies they support, performance, etc.)

  • Hyper-V Network Boot Legacy Network

    - by Carl
    Hi, I am planning out a Hyper-V R2 Cluster environment. I was wondering if I went to the effort of deploying one of the few methods to network boot from iSCSI inside the guests, whether the legacy network adapter would switch to a synthetic after boot, or whether the connection could be handed to a synthetic network after boot? This is obviously for performance reasons. MS suggests that some emulated devices are capable of switching to synthetic with integration services after boot, but doesn't specifically list all which are capable.

  • checking the status of CPU throttling: whether ON or OFF

    - by Gaurish Telang
    I am trying to install the ATLAS BLAS library which recommends that I turn if CPU throttling to do the install. How do I check if my CPU throttling is ON or OFF? I tried the suggestion of Code: ./cpufreq-selector -g performance in the /usr/bin directory as suggested elsewhere in the forum but there was no output and the control returned back to the user. I have searched everywhere but there does not seem to be a way to determine the status of the CPU throttling

  • Apache server configuration name resolution (virtual host naming + security)

    - by Homunculus Reticulli
    I have just setup a minimal (hopefully secure? - comments welcome) apache website using the following configuration file: <VirtualHost *:80> ServerName foobar.com ServerAlias www.foobar.com ServerAdmin [email protected] DocumentRoot /path/to/websites/foobar/web DirectoryIndex index.php # CustomLog with format nickname LogFormat "%h %l %u %t \"%r\" %>s %b" common CustomLog "|/usr/bin/cronolog /var/log/apache2/%Y%m.foobar.access.log" common LogLevel notice ErrorLog "|/usr/bin/cronolog /var/log/apache2/%Y%m.foobar.errors.log" <Directory /> AllowOverride None Order Deny,Allow Deny from all </Directory> <Directory /path/to/websites/> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> I am able to access the website by using www.foobar.com, however when I type foobar.com, I get the error 'Server not found' - why is this? My second question concerns the security implications of the directive: <Directory /path/to/websites/> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> in the configuration above. What exactly is it doing, and is it necessary?. From my (admitedly limited) understanding of Apache configuration files, this means that anyone will be able to access (write to?) the /path/to/websites/ folder. Is my understanding correct? - and if yes, how is this not a security risk?
