  • master-slave-slave replication: master will become bottleneck for writes

    - by JMW
    hi, the mysql database has arround 2TB of data. i have a master-slave-slave replication running. the application that uses the database does read (SELECT) queries just on one of the 2 slaves and write (DELETE/INSERT/UPDATE) queries on the master. the application does way more reads, than writes. if we have a problem with the read (SELECT) queries, we can just add another slave database and tell the application, that there is another salve. so it scales well... Currently, the master is running arround 40% disk io due to the writes. So i'm thinking about how to scale the the database in the future. Because one day the master will be overloaded. What could be a solution there? maybe mysql cluster? if so, are there any pitfalls or limitations in switching the database to ndb? thanks a lot in advance... :)

  • What do YOU use for your Windows Server backup solution?

    - by Justin Higgins
    I know there are many choices, from builtin ntbackup, to FOSS, to commercial to custom script, but I was wondering what YOUR choice is for your servers and environment and a brief explanation of why. As each environment and requirements differ, there is no one right solution, except that you should be backing up and verifying restoration regularly. As a bonus, do you use D2D2D? D2D2T? D2D2Cloud?

  • Why not install Msvcr71.dll into system32?

    - by hillu
    While looking for an authoritative source for the missing Msvcr71.dll that is needed by a few old applications, I stumbled across the MSDN article Redistribution of the shared C runtime component in Visual C++. The advice given to developers is to drop the DLL into the application's directory instead of system32 since DLLs in this directory are considered before the system paths. What can/will go wrong if I (as an administrator, not a developer) decide to take the lazy path and install Msvcr71.dll (and Msvcp71.dll while I'm at it) into the system32 directory (of 32 bit Windows XP or Windows 7 systems) instead of putting a copy in each application's directory? Is there another good solution to provide the applications with the needed DLLs that doesn't involve copying stuff to the application directories?

  • Having trouble with EPSON Stylus SX130 scanner

    - by pinouchon
    I am trying to scan files with an EPSON Stylus SX130 on windows 7 x64. When i plug in the printer, windows automatically find drivers for printing, but not for scanning. So i go to the manufacturer website to download the drivers, select windows 7 64-bit and download drivers for EPSON Scan. The install works fine, but when i try to scan a file (eg: from paint or Windows fax and scan), the folowing message pops up and freezes the application : the progress bar plays the animation forever and the application does not respond. I then have no choice to kill the application with the task manager. Do you have an idea of what's going on ? How can i fix the problem, ie: how do i get the scanner actually scan files without freezing ? I tried to install the driver from the CD given in the printer package, and got the same problem. The only help i found so far (the error seems somewhat related) is this : Install a xp virtual machine and run it in there

  • Target to browse in order to insert a file

    - by Abid
    I have created an application using PHP and HTML. I insert it in my Linux server. I open it from my windows machine using the browser. I should in this application insert a file. When i click "insert file", instead of i have a window that browse the Linux server , i get a window that browse my local machine. And when i click insert , nothing is copied to the server. The code to insert file is: Filename: <input type="file" name="file" id="file"> So what should i do to force this application to browse the Linux machine when i open it from my local machine?

  • Network email alerts

    - by stephenfalken
    I would like to buy or d/l an application that will alert our sysadmin in the event of network failure, like via email and/or phone call. I've looked around the net before posting this question, but I have one main concern: if our network goes down, how can a network monitoring application send email to alert us that it's down? Doesn't this have to be an external application that looks at our network from outside? Well anyway, I want to find something that will handle this for us - freeware if possible, sice we're not looking for heavy analysis - just simple alerts. Advice is appreciated.

  • How to invalidate nginx reverse proxy cache in front of other nginx servers?

    - by Olivier Lance
    I'm running a Proxmox server on a single IP address, that will dispatch HTTP requests to containers depending on the requested host. I am using nginx on the Proxmox side to listen to HTTP requests and I am using the proxy_pass directive in my different server blocks to dispatch requests according to the server_name. My containers run on Ubuntu and are also running a nginx instance. I'm having troubles with caching on a particular website that is fully static: nginx keeps on serving me stale content after files updates, until I: Clear /var/cache/nginx/ and restart nginx or set proxy_cache off for this server and reload the config Here's the detail of my configuration: On the server (proxmox): /etc/nginx/nginx.conf: user www-data; worker_processes 8; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; use epoll; } http { ## # Basic Settings ## sendfile on; #tcp_nopush on; tcp_nodelay on; #keepalive_timeout 65; types_hash_max_size 2048; server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; client_body_buffer_size 1k; client_max_body_size 8m; large_client_header_buffers 1 1K; ignore_invalid_headers on; client_body_timeout 5; client_header_timeout 5; keepalive_timeout 5 5; send_timeout 5; server_name_in_redirect off; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; gzip_vary on; gzip_proxied any; gzip_comp_level 6; # gzip_buffers 16 8k; gzip_http_version 1.1; gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; limit_conn_zone $binary_remote_addr zone=gulag:1m; limit_conn gulag 50; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } /etc/nginx/conf.d/proxy.conf: proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_hide_header X-Powered-By; proxy_intercept_errors on; proxy_buffering on; proxy_cache_key "$scheme://$host$request_uri"; proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=cache:10m inactive=7d max_size=700m; /etc/nginx/sites-available/my-domain.conf: server { listen 80; server_name .my-domain.com; access_log off; location / { proxy_pass http://my-domain.local:80/; proxy_cache cache; proxy_cache_valid 12h; expires 30d; proxy_cache_use_stale error timeout invalid_header updating; } } On the container (my-domain.local): nginx.conf: (everything is inside the main config file -- it's been done quickly...) user www-data; worker_processes 1; error_log logs/error.log; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; #tcp_nopush on; keepalive_timeout 65; gzip off; server { listen 80; server_name .my-domain.com; root /var/www; access_log logs/host.access.log; } } I've read many blog posts and answers before resolving to posting my own questions... most answers I can see suggest setting sendfile off; but that didn't work for me. I have tried many other things, double checked my settings and all seems fine. So I'm wondering whether I am not expecting nginx's cache to do something it's not meant to...? Basically, I thought that if one of my static files in my container was updated, the cache in my reverse proxy would be invalidated and my browser would get the new version of the file when it requests it... But I now have the sentiment I misunderstood many things. Of all things, I now wonder how nginx on the server can know about a file in the container has changed? I have seen a directive proxy_header_pass (or something alike), should I use this to let the nginx instance from the container somehow inform the one in Proxmox about updated files? Is this expectation just a dream, or can I do it with nginx on my current architecture?

  • Minimal Fedora Installation

    - by MA1
    I am working on a Fedora 13 minimal iso image with no Desktop environment. I just need wxPython support. I removed the gnome from kickstart and build the iso image using livecd-creator. But now my application is not loading as gnome is gone. Earlier my application(myapp.desktop) was placed in /usr/share/gnome/autostart/ and starts automatically. So what should i do now the run my application? To run my wxPython appalication should i have to install display manager(xdm, gdm, kdm etc..)? If i install gdm, it takes lots of space. what should i do? In short i need Fedora 13 minimal iso image with no desktop environment and with wxPython support.

  • How can I launch RemoteApp on Windows Server from server itself at startup

    - by Rusted
    I have Windows Server 2008 R2 with RDS and custom desktop (GUI) application installed on the server. The app is started as RemoteApp on server by user from his desktop computer (or, sometimes, he can work from notebook over VPN). Some details about environment: the server automatically shuts down every evening and automatically power-on every morning (this is a requirement) desktop application do some precalculations/precaching on startup and it can take lot of time mentioned application have some memory leaks, so I can't use hibernate instead of shutdown When user launching this app from his computer, he can't start work with it until this app finishes pre-initialization. Is there any way to start RemoteApp session at the server startup (without actual user logon), so that the user could connect to this session from his computer later? I don't want to involve the user's computer to make it work. I have tried to do it by Windows startup script, but have no luck - starting RDP session requires actual user session.

  • Connect android to database

    - by danny
    I am doing a school project where we need to create an android application which needs to connect to a database. the application needs to gain and store information for people's profiles on the database. But unfortunatly we are a little bit stuck at this point because there are numerous ways to link the application such as http request through apache or through the SOAP/REST protocol. But it's really hard to find good instructions or tutorials on the problem since I can't really find them. Maybe that's cause i'm probably using the wrong words on google. Unfortunately I have little relevant information. So if anyone can help me with finding relevant links to good online tutorials or howto's than those are very welcome.

  • Sending emails with remote mail server in ASP.NET blocked by Windows firewall?

    - by Dave
    I want to migrate a web application from a Windows Server 2003 to a Windows Server 2008 R2. All works fine except sending emails from the application. If I configure the application to use the smtp server on "localhost" it works, but changing it to the "real" host name (e.g. mail.example.org) no mail is sent. The error message says, that the remote server needs a secure connection or smtp authentication. But since it works when using "localhost" instead of the host name I doubt that this is the problem. Also it's unlikely a problem with the mail server, I also tried it with another one. So for me it seems like the firewall is blocking the outgoing connection to the mail server. I tried to open port 25, but it still did not work. Maybe I just did it the wrong way.

  • Passenger, Apache and avoiding page caching

    - by user38382
    I'm hosting a rack application with passenger and apache. The application is setup to cache the content of each request to the public directory after each request. This allows apache to serve the content directly as a static page for future requests. I would like to tell Apache, presumably through some rewrite rules that any requests with query parameters should not be cached, but instead passed down to the rack application. With a mongrel setup I would just redirect it to the balancer if it meets my rewrite conditions. How do you do the same with passenger?

  • Is there some standard way to publish a calendar feed?

    - by CMP
    For a web application I am working on, I would like to be able to give the user a single url that they can enter into the calendar application of their choosing to have events from our application show up in their calendar. Most other sites I have seen that do similar things will have a one time download of an .ics file that can be imported. If I have to require my users to download a new file every time the schedule changes, it sort of defeats the purpose of having the feed at all. The calendar can change many many times a day. What I would really like is something like rss where their calendar program can look up a url and automatically see the most recent data. Does anything like this exist? Our main target is mobile devices, so it really should be supported by iCal and google Calendar. Anything else is bonus.

  • PHP Mail Relay via Remote smtp Server

    - by Toqeer
    We have a php application running on Linux which sends emails to there users. Currently its setup like php.ini is configured to send via local sendmail server but we have separate mail server for our organization for this domain. I want to send the php application emails via that remote smtp server so these emails can have the correct SPF records and sign via DKIM. But I could not see such option in php.ini to specify the remote host address to forward emails to that, its for windows only. I saw some post which suggest phpMailer but I could not find how to configure that so all our php application could send via our remote SMTP.

  • Configure sendmail to accept connection from one other IP address

    - by Kumala
    I have a RubyOnRails application running on the same server that runs sendmail. The application sends out (no need to receive) emails via the local sendmail. Now I intend to move sendmail to a dedicated server. How do I make sendmail on that server accept connections from my application on the other server? I modified sendmail.mc from DAEMON_OPTIONS(`Family=inet, Name=MTA-v4, Port=smtp, Addr=127.0.0.1')dnl to DAEMON_OPTIONS(`Family=inet, Name=MTA-v4, Port=smtp')dnl I have also added to /etc/mail/access: Connect:198.211.117.41 RELAY then ran m4 sendmail.mc > sendmail.cf and restarted sendmail. Trying to connect from my app server with telnet on port 25 to the mail server gives me: telnet: Unable to connect to remote host: Connection refused Am I missing something?

  • How can I create multiple identical AWS EC2 server instances with large amounts of persistent data?

    - by mojones
    I have a CPU-intensive data-processing application that I want to run across many (~100,000) input files. The application needs a large (~20GB) data file in order to run. What I would like to do is create an EC2 machine image that has my application and associated data files installed boot up a large number (e.g. 100) of instances of this image split my input files up into 100 batches and send one batch to be processed on each instance I am having trouble figuring out the best way to ensure that each instance has access to the large data file. The data file is too big to fit on the root filesystem of an AMI. I could use Block Storage, but a given Block Storage volume can only be attached to a single instance, so I would need 100 clones. Is there some way to create a custom image that has more space on the root filsystem so that I can include my large data file? Or is there a better way to tackle this problem?

  • Troubleshooting a crash with Windows 7

    - by AngryHacker
    I have a folder with several thousand videos (All .MPG extensions). When I open the folder with these videos, it shows up fine, but as I start scrolling down, it crashes the Windows Explorer. In the Event Viewer, I see this: Faulting application name: Explorer.EXE, version: 6.1.7600.16450, time stamp: 0x4aebab8d Faulting module name: ntdll.dll, version: 6.1.7600.16559, time stamp: 0x4ba9b802 Exception code: 0xc0000374 Fault offset: 0x00000000000c6df2 Faulting process id: 0x954 Faulting application start time: 0x01cbb1b71edf3b51 Faulting application path: C:\Windows\Explorer.EXE Faulting module path: C:\Windows\SYSTEM32\ntdll.dll Report Id: ee987372-1dc4-11e0-8e06-406186ea9135 I suspect that one of the videos has bad metadata. I removed the Length column and it was still crashing. I then removed the Date column and the problem disappeared. How do I go about troubleshooting this problem or at least identifying the file that's causing the issue.

  • Looking for fault-tolerant, multi-CD/DVD burning software

    - by MichaelKay
    A few years back, I saw an open-source application that created fault-tolerant, multi-CD backup sets. The thought was that if a few sectors went bad on one CD, the data could be reconstructed from others similar to a RAID 5 hard-drive setup. I did some searching and I could not find the application again. Does anyone know of a application that works in this manner. It needs to work with both CDs & DVDs. Linux or Windows will be OK.

  • SQL Server 2008R2 Express: which is the users limit in a real case scenario?

    - by PressPlayOnTape
    I know that sql server express has not a user limit, and every application has a different way to load/stress the server. But let's take "a typical accounting software", where users input some record, retrieve some data and from time to time they make some custom big queries. May someone share its own experience and tell me which is the limit of users that can realistically use a sql server express instance in this scenario? I am looking for an indicative idea, like (as an example): "I had a company with an average of 40 users logged in and the application was working ok on sql server express, but when the users become 60 the application started to seem non repsonsive" (please note this sentence is pure imagination, I just wrote it as an example).

  • How can I register a custom protocol with xdg?

    - by julien
    I've been struggling this morning trying to associate an application with a custom protocol, namely emacsclient and org-protocol. I'm calling this protocol from a webbrowser bookmarklet, and I get the following behaviour : In chromium, the "Launch Application" dialog comes up, and calls xdg-open org-protocol://... which ends up firing a new chromium frame. In firefox, I've tried setting network.protocol-handler.app.org-protocol to an empty string or my emacsclient path, anyhow I get the following error message : "Firefox doesn't know how to open this address, because the protocol (org-protocol) isn't associated with any program" without even showing any external application selection dialog. I'm not using any desktop environment, so I need to make this work strictly with xdg, however, despite reading the shared mime info spec etc, I still can't fathom a working configuration.

  • Eventlog entry for allowed connection in Windows Firewall

    - by Jaap
    I was seeing a lot of entries in the eventlog: The Windows Filtering Platform has permitted a connection. Application Information: Process ID: 4 Application Name: System Network Information: Direction: Inbound Source Address: 10.xxx.xxx.xxx Source Port: 80 Destination Address: 10.xxx.xxx.xxx Destination Port: 31773 Protocol: 6 Filter Information: Filter Run-Time ID: 67903 Layer Name: Receive/Accept Layer Run-Time ID: 44 We have a loadbalancer which checks every second to see if the application is still running (a health check). The logs contain large amounts of this kind of entries, which makes the Event Viewer slow and it's difficult to find the more interesting logs. How do I make sure these messages don't end up in the event logs?
