  • mysql 5.1 - innodb - query_cache_size - 9,418,108 queries have been removed from the query cache due to lack of memory

    - by Tom C
    Currently running on a 16GB system - Ubuntu 64 bit. INnodb Buffer Pool is set to 10GB. tuning-primer shows the following: QUERY CACHE Query cache is enabled Current query_cache_size = 512 M Current query_cache_used = 501 M Current query_cache_limit = 4 M Current Query cache Memory fill ratio = 97.87 % Current query_cache_min_res_unit = 4 K However, 9418108 queries have been removed from the query cache due to lack of memory Perhaps you should raise query_cache_size That is over 9million queries removed. System uptime is 8 days. Should I remove the Query Cache altogether? Our db is always under heavy I/O. tia

  • Autosaving on emacs or xemacs files (preferably on loss of focus)

    - by Spencer
    Ideally I want to replicate with emacs functionality from TextMate, whereby on loss of focus i.e. I click away from the buffer, my file saves. If this isn't possible, I want to customize emacs so that it will autosave the file for every character I write. When I say this I don't mean I want to autosave to the ~ backup files. I want to save the file I am currently working on. I am working on a Fedora VM. Note I am not looking for a backup or autosave. I want the file I am actually in to save, so that if I loaded the html file I am editing in a web browser it would reflect my new changes without me having to explicitly change it.

    - by Debabratta
    I have an webapplication written mainly in jsp and servlet and I use tomact7.0.26 as my application server. I want this application to run by IIS though I can run it using tomcat.

So please tell me the steps for required configuaration. Thankyou.

  • Poor TCP loopback throughput on Windows

    - by Yodan Tauber
    I measured the throughput of a locally bound TCP socket connection on my computer (Intel Q9550, 64 GB RAM, Windows XP 64 bit) using iperf. I got dissatisfying results (around 1.6 Gbit/s) each time, no matter how I tweaked the TCP settings (buffer length, window size, max segment size, no delay). I got similar results when I tried netperf. Now, I understand (from sources like these) that the average throughput of a loopback connection should be around 5 Gbit/s. What could be the reasons for such poor performance?

  • Why is my htaccess file preventing access to my MP3 file?

    - by Andrew
    My Zend Framework application has a public directory which contains an htaccess file. If the file isn't found in the public directory, it routes the request through the application. I have an MP3 file within my public directory, but the htaccess file is routing the request through the application! Do you see anything wrong with my htaccess file?

  • display sql syntax in Oracle's sqlplus?

    - by user1375963
    What is in Oracle's sqlplus equivalent of Linux's man or --help ? When I'm in sqlplus and type help index, I get some commands displayed, but there is no way to get specific sql syntax. For example if I type 'help select' I get: SP2-0172 No HELP matching this tiopic was found. Of course, I would like to get all available options for select command. How can I get info or sql syntax while I'm at sql prompt ? Thanks

  • "bin/sh: can't access tty; job control turned off” error when running shellcode"

    - by Nosrettap
    I'm writing shellcode to exploit a buffer overflow vulnerability on a server. To do so I have port binding shellcode that I send to the server and then I run (from a linux terminal) the command telnet serverAdress 4444 where 4444 is the port which I have opened up. The hope is that I will receive a shell back that I can use to execute commands. However, I always end up with the command bin/sh: can't access tty; job control turned off I can't change any of the server code, and I believe the shellcode is correct because I got it from this website (http://www.tsirogiannis.com/exploits-vulnerabilities-videos-papers-shellcode/linuxx86-port-binding-shellcode-xor-encoded-152-bytes/). From my research, it appears that this may have to do with the mode that my terminal is running in (something called interactive mode...or something like that). All computers involved are linux machines and the machine that I am on is running the latest version of Ubuntu. Any ideas what this job control error means and how I can fix it?

  • how to get a decent emacs setup on linux

    - by Hersheezy
    I am currently interested in switching from vim to emacs. One of the more compelling reasons for this is the smooth integration with a unix environment. The most experienced emacs users I have seen have a bash prompt at the bottom of their window, with stdout going to a buffer right above it. They then interact with the output of programs such as grep in interesting ways. I am on Ubuntu 10.04 and the default emacs environment does not seem to do much for me in the way of integration. For example, in the M-x shell mode, output from basic commands like ls produce lots of strange characters and hitting the up arrow does not go to previous commands. Any recommendations on a good direction to go in?

  • How to setup RAID partitions with parted?

    - by psycketom
    I'm going through the https://wiki.archlinux.org/index.php/RAID guide in here, but I'm stuck on Partition Tables. Since my drives are 3TB, fdisk and cfdisk won't cut it due to their 2GB limit, but they are straight forward when managing partitions - adding da or fd as types. But, there is not that straight forward guide for RAID partition setup with parted. So, how do I make Non-FS or RAID partition with parted?

  • Transparently rewrite requests to a subdomain.

    - by ptrin
    I would like to rewrite requests to http://www.mysite.com/foo to http://foo.mysite.com without the user's address bar changing. Using IIRF I can do the rewrite, but only if I use the [R] modifier flag which makes the rewrite a redirect. Is there a way for me to transparently rewrite requests to a subdomain? Here's the rewrite rule I've been testing with: RewriteRule ^/foo/(.*)?$ http://foo.mysite.com/index.html?$1 [R,L]

  • Is it safe to use up all memory on linux server, not leaving anything for the cache?

    - by Temnovit
    I have a CentOS server fully dedicated to MySQL 5.5 (with innodb tables mostly). Server has 32 GB RAM, SSD disks, and avarage memory usage looks like this: So about 25GB is in use and about 6.5GB is cached. I am experiencing performance problems with WRITE queries, so I was thinking, is this the optimal cache size? I might increase innodb buffer size, so that linux cache would become smaller, or decrease it, so it would be bigger. What is the optimal used/cached memory balance for busy MySQL server on linux?

  • 403 error with codeignitor

    - by DJB
    When I type in the standard web address for my site, I get a 403 error. However, when I type in a more exact address, say pointing to an index.php file, everything shows up fine. I'm using Anodyne Productions' Nova (SMS 3) which uses codeignitor. All accompanying software (PHP/MySQL) is compatible. I'm not a very technical person, so I'm hoping that this is an easy fix. Thanks for taking the time to answer.

  • Improving sound quality with remote ESD server

    - by cuu508
    Hi, I'm investigating low-budget ways to get audio from my PC (Ubuntu) to HiFi without wires. I'm currently testing a setup where Asus WL-500gP wireless router runs ESD daemon and has attached USB soundcard which is then plugged into HiFi. I'm testing playback on PC with mpg123-esd and Spotify under Wine. The sound is there, latency is unexpectedly low, but I also hear occassional clicks and some distortion from time to time. I suppose that's because of the low latency and wireless streaming of uncompressed audio--any packet drops, CPU temporarily being busy etc. will cause clicks in sound output. Is there a way around this problem, increasing latency / buffer size somehow perhaps? Streaming using shoutcast protocol seems to be a way out but I have feeling that would be a complex and brittle setup.

  • Make thunderbird store all mail locally for IMAP accounts but not indexing all for search

    - by rubo77
    In Thunderbird the global gloda search is connected to the selection of downloaded/syncronized folders of the IMAP accounts in the Offline-settings. Is it possible somehow, that Thunderbirds download/syncs all emails in the IMAP account but does not add them to the index for the global search? I would like to do this because I have some accounts that I only keep in thunderbird for archiving reasons but I don't want to find those mails, when I use the global search

  • Experiences with eXdupe?

    - by ewwhite
    I noticed that the eXdupe compression/archiving/deduplication utility was recently mentioned in another post here. It boasts some interesting features, and I've been playing with it for the past day. It's basically a cross-platform, highly multithreaded archival tool. http://exdupe.com/index.html I'm curious if anyone here uses it in production or has any tips on how to leverage the tool in their environment. I'm looking for suggestions.
