• Deploying ASP.NET MVC to Windows Server 2003

  - by pete the pagan-gerbil

  Hi, I have a problem with an MVC 2 website on Windows Server 2003 running IIS 6. It is externally hosted, but we have a 2003 server internally for testing. The internal server runs the website fine, the external server gives a 403 ("website declined to show this page") error when navigating to the root of the site, and a 404 if I try to navigate directly to a page resource. I have tried the wildcard ISAPI mapping and extension mapping, and a couple of other common checks (I forget exactly which now, most of them were already set correctly), but so far no joy. All the settings can be replicated on our internal server and the pages return properly. IIS logs just show exactly what the browser shows - 404 errors and 403s. I've read about a different level of trust required for an MVC application compared to a WebForms application - how can I check permissions and trust levels on the external and internal servers (assuming I am able to check that) and if that would cause these errors, what are the minimum levels that MVC require? Failing that, what else might be causing this error for me to try out?

• Can a folder on a NAS be made available as a physical drive in VMWare?

  - by asbjornu

  We are currently in the process of moving from a single web server to two load balanced web servers and are facing some challenges we don't quite know how to fix. One of these is that the current single server hosts applications that write stuff to disk. The applications running on the server expects that when something is written to disk it later will in fact exist, so it's important that this premise is fulfilled with the dual server architecture as well. The dual server setup is a couple of VMWare instances with Windows Server 2008 R2 as the guest operating system. Out of the box, these instances does not share any kind of file system, so just moving the applications over would make them break since one instance would write something to the file system that doesn't exist on the other. Thus we need to share a file system between the two virtual servers. Our host has proposed to create a network share on a SAN and map this share individually on each virtual machine. This doesn't work too well due to NTFS permissions, etc., because the share needs to be accessed by several independent web applications that won't even be in the same application pool. The only solution that kind of works is to hard code an "identity" for each web application into its web.config file, but this means password in clear text which doesn't sit well with me. Since the servers are virtual, I'm thinknig: Wouldn't it be possible to make a NAS area available as a physical disk in the gues operating system somehow? Since VMWare has full control of the virtual hardware, you'd think it would be able to "fake" a local hard drive in the virtual machine that in reality is a folder on a NAS, but so far I haven't found anything that states how and if this is possible. So I have to ask the wonderful Server Fault community: Can a folder on a NAS be made available as a physical drive (typical D:) in both of the virtual machines?

• Apache reverse proxy with VirtualHost not serving a page

  - by Mr Aleph

  I have an Apache reverse proxy set to move requests to a Tomcat Applet. The config is similar to: <VirtualHost 100.100.100.100:80> ProxyPass /AppName/App http://1.1.1.1/AppName/App ProxyPassReverse /AppName/App http://1.1.1.1/AppName/App </VirtualHost> I also have a page called summary.html that exists on 1.1.1.1 as: http://1.1.1.1/AppName/summary.html When I browse directly to it I have no problem viewing it, however if I try to get there via the reverse proxy I get a blank page. Wireshark shows me a 503, but this one is coming from the Apache reverse proxy (IP 100.100.100.100) and not the Tomcat (IP 1.1.1.1). Should I add http://1.1.1.1/AppName/ to the config? How? I tried it but I get a blank page, however this one shows on the URL bar of the browser the internal IP of the Tomcat, so, no go. Help is appreciated. Thanks. EDIT: This is the dump from Wireshark: GET /AppName/ HTTP/1.1 Host: 100.100.100.100 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/534.52.7 (KHTML, like Gecko) Version/5.1.2 Safari/534.52.7 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Cache-Control: max-age=0 Accept-Language: en-us Accept-Encoding: gzip, deflate Connection: keep-alive HTTP/1.1 404 Not Found Date: Tue, 30 Jan 2012 09:08:51 GMT Server: Apache Content-Length: 1 Connection: close Content-Type: text/html; charset=iso-8859-1

• Correct use of SMTP "Sender" header?

  - by Eric Rath

  Our web application sends email messages to people when someone posts new content. Both sender and recipient have opted into receiving email messages from our application. When preparing such a message, we set the following SMTP headers: FROM: [email protected] TO: [email protected] SENDER: [email protected] We chose to use the author's email address in the FROM header in an attempt to provide the best experience for the recipient; when they see the message in their mail client, the author is clear. To avoid the appearance of spoofing, we added the SENDER header (with our own company email address) to make it clear that we sent the message on the author's behalf. After reading RFCs 822 and 2822, this seems to be an intended use of the sender header. Most receiving mail servers seem to handle this well; the email message is delivered normally (assuming the recipient mailbox exists, is not over quota, etc). However, when sending a message FROM an address in a domain TO an address in the same domain, some receiving domains reject the messages with a response like: 571 incorrect IP - psmtp (in reply to RCPT TO command) I think this means the receiving server only saw that the FROM header address was in its own domain, and that the message originated from a server it didn't consider authorized to send messages for that domain. In other words, the receiving server ignored the SENDER header. We have a workaround in place: the webapp keeps a list of such domains that seem to ignore the SENDER header, and when the FROM and TO headers are both in such a domain, it sets the FROM header to our own email address instead. But this list requires maintenance. Is there a better way to achieve the desired experience? We'd like to be a "good citizen" of the net, and all parties involved -- senders and recipients -- want to participate and receive these messages. One alternative is to always use our company email address in the FROM header, and prepend the author's name/address to the subject, but this seems a little clumsy.

• How should I perform database maintenance on a 24x7 system

  - by solublefish

  I'm a software developer who inherited a part-time DBA role. I'm responsible for an application backed by a small, high-volume 24x7 database on SQL Server 2008. While there's other stuff in the DB, the critical piece is a 50GB, 7.5M row table that serves 100K requests/sec during peak load, and about half that at "night". This is 99%+ read traffic, but the writes are constant, and required. I need to be able to perform periodic maintenance without a maintenance window. Say an index rebuild, a job to purge old data, Windows Update, or hardware upgrade. Most of the advice I've seen is along the lines of "MAKE a maintenance window." While I appreciate the sentiment, I hope there's another way. If it will solve this problem, I do have the ability to purchase new hardware or modify the database, the clients (a set of web services servers), and much of the application code (ADO.NET + ASP.NET). I've been thinking along the lines of using the warm spare (or a 3rd server) to do the maintenance, and then "swap" it into production. 1 Synchronize the spare by restoring backups, including a current transaction log. 2 Perform the maintenance tasks. 3 Reconfigure clients to connect to the spare server. Existing connections are finished within a minute or so. 4 The spare server is now the production server. The problem remaining is that the new production server is now out of date by however long it took to perform maintenance. Is there some way that the original production server can be made to queue up changes and merge them to the spare between steps 2 and 3? Any other ideas?

• nginx & php-fpm and custom header

  - by nixer

  I would like to pass some custom header (ACCESS_TOKEN) from client RESTful application (JS) to application server (php-fpm). I had read that nginx should pass all http headers to php, but somehow it does not come to my php :( I can see it in firebug http://o7.no/N6DM7q but can't see it in $_SERVER variable. it just does not exist in $_SERVER array. I'm thinking that i need to pass it manually. Now my config looks like that: location @php-fpm { include /etc/nginx/fastcgi_params; fastcgi_pass unix:/tmp/php5-fpm.sock; fastcgi_param REQUEST_URI /index.php$request_uri; fastcgi_param SCRIPT_FILENAME /htdocs/index.php; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_param DOCUMENT_ROOT /htdocs; } } and when I add new line in location definition: location @php-fpm { include /etc/nginx/fastcgi_params; ... fastcgi_param ACCESS_TOKEN $http_access_token; } } or even if i will add it into fastcgi_params file it does not help :( if I put into location part next line: fastcgi_param ACCESS_TOKEN $http_access_token; then in php it has empty value :( how I can pass custom header from client to backend (php) via nginx ?

• NFS confusion - writing many small files

  - by Antonis Christofides

  I have a Debian squeeze amd64 which is at the same time a NFS4 server and client (it mounts itself through NFS4). The local directory that leads directly to disk is /nfs4exports/mydir, whereas /nfs4mounts/mydir is the same thing mounted through NFS, using the machine's external IP address. Here is the line from fstab: 176.9.116.102:/mydir /nfs4mounts/mydir nfs4 soft 0 0 I have an application that writes many small files. If I write directly to /nfs4exports/mydir, it writes thousands of files per second; but if I write to /nfs4mounts/mydir, it writes 4 files per second or so. I can greatly increase speed if I add async to /etc/exports. (Writing a single large file to the NFS directory goes at more than 100 MB/s.) I am confused by the description of async in NFS. If my application accesses the local directory, system calls like write and close return even if caches have not been flushed to permanent storage. Apparently this is not true with NFS sync behaviour. However, with NFS async behaviour, even calls like fsync are ignored. Isn't it possible to work like local files, i.e. generally work asynchronously, but honour fsync and O_SYNC?

• legitimacy of the tasks in the task scheduler

  - by Eyad

  Is there a way to know the source and legitimacy of the tasks in the task scheduler in windows server 2008 and 2003? Can I check if the task was added by Microsoft (ie: from sccm) or by a 3rd party application? For each task in the task scheduler, I want to verify that the task has not been created by a third party application. I only want to allow standards Microsoft Tasks and disable all other non-standards tasks. I have created a PowerShell script that goes through all the xml files in the C:\Windows\System32\Tasks directory and I was able to read all the xml task files successfully but I am stuck on how to validate the tasks. Here is the script for your reference: Function TaskSniper() { #Getting all the fils in the Tasks folder $files = Get-ChildItem "C:\Windows\System32\Tasks" -Recurse | Where-Object {!$_.PSIsContainer}; [Xml] $StandardXmlFile = Get-Content "Edit Me"; foreach($file in $files) { #constructing the file path $path = $file.DirectoryName + "\" + $file.Name #reading the file as an XML doc [Xml] $xmlFile = Get-Content $path #DS SEE: http://social.technet.microsoft.com/Forums/en-US/w7itprogeneral/thread/caa8422f-6397-4510-ba6e-e28f2d2ee0d2/ #(get-authenticodesignature C:\Windows\System32\appidpolicyconverter.exe).status -eq "valid" #Display something $xmlFile.Task.Settings.Hidden } } Thank you

• How can I safely close this window and forever avoid seeing similar pop-ups from Mackeeper Zeobit's malware and spyware?

  - by Michael Prescott

  The attached image shows a window that just popped up and the only button available is the OK button. I could Force quit Safari, but I've got several sites open right now and don't want to try and find my place again. Besides, I've seen similar hacks in the past and I'd like to learn how to handle them in a way better than just a brute force-quit. I've never heard of MacKeeper or Zeobit, so I opened Firefox and did a few searches while Safari is obviously still stuck, waiting for me to click the sneaky OK button in the dialog window. Anyhow, at least the first few pages of most search results contain lots of blabbering from questionable witnesses about how MacKeeper saved them from some malware or spyware. However, any company that is hacking the browser to maliciously install their product is itself the criminal and not providing a true security application. So, there are three questions here: How can I close this window? Can I do something to Safari to avoid these hacks in the future? (Just curious) Is MacKeeper or Zeobit somehow loading the search results so that no information about their application being malware or spyware is listed (I can't be the only person in the world that is offended by their tactics, even though it appears I am)?

• Intermittent extrememly long response times when downloading documents

  - by pap

  I have a Java web application running om Tomcat 7 with an Apache httpd 2.2 fronting with mod_jk/AJP. One part of the application is serving files (up to 4mb size). Now, normally this all runs very smooth with stable, low response-times. However, in rare instances (<0.1% of downloads), the downloadtime will go beyond 1 minute. After activating the ThreadStuckValve in Tomcat, I can see that the long responses seem to be stuck at org.apache.tomcat.jni.Socket.sendbb(Native method) i.e network I/O. At most, these long-running downloads take 5 minutes, which I strongly suspect is because of the default 300 second timout in Apache 2.2 (http://httpd.apache.org/docs/2.2/mod/core.html, "TimeOut directive"). To me, this looks like network problems. The Apache timeout (if that is what is kicking in at the 5 minute mark) indicates that ACK packets are not being transmitted correctly. My questions are what could be causing this? Closed browser at receiving end but socket not signaled as closed properly? Packet loss or some other network failure in transit? Where would I start troubleshooting this? We're running Tomcat and Apache on Windows server 2008-R2 in a vmware virtualized server.

• Windows Server 2008 - inexplicable system time jumps/glitches/inaccuracies

  - by Nathan Ridley

  I'm running a production web server on Windows Server 2008. On this server I have a database which logs certain user actions, but every now and again I inexplicably get database entries which, according to the record ID and the records immediately before and after, have the wrong time logged against them (7 days+ too old). For example, record ID 1001 will be for Dec 7, 11pm, 1002 will be for Dec 7, 11:01pm, then 1003 will be for Nov 28, 1:38am, then the next will be back on track again. The problem seems to occur in random records (or 2-3 records in a row) and crops up once every few days. This is absolutely baffling because there is only one place in the application that assigns this date/time value and it's simply the system UTC date. I have been synchronizing the system time to time-a.nist.gov (which I read in another article was a bit more reliable than the default time.windows.com) and it seems to occasionally get out of time anyway (3-4 minutes), but I'm speculating that occasionally the time server has a temporary glitch where the date changes to a drastically wrong value for a short space of time, then changes back. Either that, or the motherboard clock battery is screwed and the reason the time momentarily changes is that the motherboard loses the time and then the time synchronization puts it back again. Could either of my suspicions be right? Should I turn off time synchronization for a production server? Assigning dates to an event log where the dates are up to 2 weeks prior to the actual date is a severe problem I can't have when the next version of my application is released. Any suggestions or advice would be appreciated.

• How to determine the root cause of a system lockup on Ubuntu 8.04 LTS?

  - by jdt141

  I'm currently working a project that involves setting up a PC/104 stack and running Ubuntu 8.04 LTS. We need to use the PC/104 stack because its an embedded application - and we're required to use a DeviceNet peripheral card to communicate to other devices. (DeviceNet is just a protocol on top of CAN.) Anyway, the following hardware is on the stack: Kontron MOPSPM104 with a 1GHz Intel Celeron processor ConnectTech FlashDrive/104 4GB Industrial Temp (-40 to +85 C) Woodhead (Molex) PC104DVNIO DeviceNet card A run of the mill 104 power supply The Kontron Board offers two serial ports, one VGA out, and two USB ports. The DeviceNet card is an ISA card. Because of this (per the User's Guide for the Kontron Board), I have manually set the IRQs in the BIOS to be appropriately configured, and turned off ACPI in both the BIOS and passed the appropriate flag in GRUB. I've installed Ubuntu 8.04 desktop, 32 bit. The problem that I'm having is that, from time to time, the entire 104 stack locks up. This only seems to happen in two cases, both of which we're running GNOME. We have a custom application that uses the DeviceNet card, and the system will lock up, or (more frequently) when we're running Firefox and either surfing for some information or trying to test it - typically by streaming video from a IP-camera. The reason I ask this questions is I cannot determine the root cause of this lockup. The IRQs appear to correctly configured in the BIOS and as the Kernel sees them, and nothing is logged to dmesg. If you all could help me determine the root cause of this lockup, I would greatly appreciate it. Thanks.

• How can I backup entire installations of a program, instead of just manually backing up individual f

  - by NoCatharsis

  It seems pretty straightforward to backup individual files, such as pictures, saved games, or settings files - just copy them straight over to your 2nd HDD or to an online service like DropBox. However, is there any way to backup entire installations of a program? For instance, my Firefox directory has a lot of personal customizations and add-ons. I don't want to go through each item and decide to back it up or let it go. So my next option is to copy out the entire directory for backup. But, if I copy the entire directory back onto the HD after a format, it is not an integrated installation and this seems like it could be troublesome. I would assume Windows cannot detect the directory for uninstallation, or would not let you choose Firefox as your default browser, right? I'm no pro, but this sounds like a bad idea. So my question is whether there is a good way to preserve all necessary files, while also preserving the full installation process of an application. This is not specific to Firefox - I would like to know how to do this for any application. Thank you.

• PHP files are downloaded, not executed in UserDir on Apache

  - by Fabian

  We're running a webserver using Debian 6.0.3 with Apache 2, we recently upgraded from Debian 5 to 6. Since then php scripts in the user directories (using mod_userdir) have stopped working, they are downloaded instead of being executed. There is also a website using php outside of the user directories, and that one continues to work fine, so PHP seems to generally work on the server. I tested it with several PHP files, among the a simple phpinfo file that works fine on the main site, but is just downloaded when copying it to one of the user directories. The php files and the directory containing them are executable for everyone. The option in the Apache php5.conf that by default disables PHP in the user directories, is commented out, so the php5.ini looks like this: <IfModule mod_php5.c> <FilesMatch "\.ph(p3?|tml)$"> SetHandler application/x-httpd-php </FilesMatch> <FilesMatch "\.phps$"> SetHandler application/x-httpd-php-source </FilesMatch> # To re-enable php in user directories comment the following lines # (from <IfModule ...> to </IfModule>.) Do NOT set it to On as it # prevents .htaccess files from disabling it. #<IfModule mod_userdir.c> # <Directory /home/*/public_html> # php_admin_value engine Off # </Directory> #</IfModule> </IfModule> We restarted Apache after changing this. I'm running out of ideas now what the problem could be, and I don't know how I could really determine which problem is preventing those php files from being executed. Any ideas on how I can solve this? Update: Strangely, PHP seems to work fine in subfolders of user directories, so if I copy a PHP file from /home/user/public_html/ to /home/user/public_html/test/ it suddenly works.

• IIS 7.5 fails to open database after computer machine on that database server is working restarts.

  - by Jenea

  Hi. I decided to post this question also here in case the issues we have is related to sql server. There is a problem that bother me for some time. I have an asp.net mvc that uses NHibernate for modeling the database. The infrastructure is the following: Windows 2008 R2 for all virtual machines. IIS 7.5 is working on one virtual machine. Sql Server 2008 is working on another virtual machine. We have couple of databases, two that stores application data and one that registers all unhandled exceptions. Sometimes virtual machine that hosts database server restarts (in the middle of the night, not quite sure about the reason) after that connection to the databases that stores application data is not working and as result there are thousands of unhandled exceptions that get registered in the third database. Important to mention that databases are accessible from Management Studio. The problem is solved by resetting IIS. Connetion are handled via NHibernateUtil class which opens and closes session at each request.

• Getting 404 error on MVC web-site

  - by RB

  I have an IIS7.5 web-site, on Windows Server 2008, with an ASP.NET MVC2 web-site deployed to it. The website was built in Visual Studio 2008, targeting .NET 3.5, and IIS 5.1 has been successfully configured to run it as well, for local testing. We've installed the world's simplest MVC application (the one which is created when you create a new MVC2 project in Visual Studio), and we are getting 404s on any page we try and access - e.g. <my_server>/Home/About will generate a 404. I've asked this question on StackOverflow as well, but that was before I knew it was a server issue. I have checked the following things: There are 404 entries in the IIS log, corresponding to each request. The application pool for the web-site is set to use the Integrated pipeline. The "customErrors" mode is set to off. .NET 3.5 SP1 is installed ASP.NET MVC 2 is installed I've used MVC Diagnostics to confirm all MVC DLLs are being found. ASP.NET is enabled in IIS, which we've demonstrated by running the MVC Diagnostics page. KB 2023146 did highlight that HTTP Redirection was off, so we've turned it on, but no joy. Any ideas will be greatly appreciated! Someone did suggest that there might be problems running it caused by Windows Server 2008 being 64-bit - does anyone know anything about this?

• Is having a [high-end] video card important on a server?

  - by Patrick

  My application is quite interactive application with lots of colors and drag-and-drop functionality, but no fancy 3D-stuff or animations or video, so I only used plain GDI (no GDI Plus, No DirectX). In the past my applications ran in desktops or laptops, and I suggested my customers to invest in a decent video card, with: a minimum resolution of 1280x1024 a minimum color depth of 24 pixels X Megabytes of memory on the video card Now my users are switching more and more to terminal servers, therefore my question: What is the importance of a video card on a terminal server? Is a video card needed anyway on the terminal server? If it is, is the resolution of the remote desktop client limited to the resolutions supported by the video card on the server? Can the choice of a video card in the server influence the performance of the applications running on the terminal server (but shown on a desktop PC)? If I start to make use of graphical libraries (like Qt) or things like DirectX, will this then have an influence on the choice of video card on the terminal server? Are calculations in that case 'offloaded' to the video card? Even on the terminal server? Thanks.

• Execute encrypted files but don't let anybody read them.

  - by Stebi

  I want to provide a virtual machine image with an installed web application. The user should be able to boot the vm (don't login, just boot) and a webserver should start automatically. The point is I want to hide the (ruby) source code of the web application from everyone as there is no obfuscator for ruby. I thought I could use file system encryption to encrypt the directory with the sourcecode (or even a whole partition). But the webserver user must be able to read it automatically after booting. Nobody is allowed to login as the webserver user (or any other user) so no other can read the contents. My questions are now: Is this possible? Because I give away the whole vm everybody could mount its virtual discs and read them (except the encrypted one). Is it now possible to find the key the webserver user needs to decrypt the files and decrypt them manually? Or is it safe to give such a vm away? The problem is that everything needed to decrypt must be included somewhere in the vm else the webserver cannot start automatically. Maybe I'm completely wrong and you have another tip for me securing the source code.

• TLS_REQCERT and PHP with LDAPS

  - by John

  Problem: Secure LDAP queries via command-line and PHP to an AD domain controller with a self-signed certificate. Background: I am working on a project where I need to enable LDAP look-ups from a PHP web application to a MS AD domain controller that is using a self-signed certificate. This self-signed certificate is also using a domain name that is not a FQDN - think of something like people.campus as the domain name. The web application would take the user's credentials and pass them on to the AD domain controller to verify if the credntials are a match or not. This seems simple, but I am having problems trying to get PHP and the self-signed certificate to work. Some people have suggested that I changed the TLS_REQCERT variable from "request" to "never" within the OpenLDAP configuration. I am concerned that this might have larger implications such as a man-in-the-middle attack and I am not comfortable changing this setting to never. I have also read some places online where one can take a certificate and place it as a trusted source within the openldap configuration file. I am curious if that is something that I could do for the situation that I have? Can I, from the command line, obtain the self-signed certificate that the AD domain controller is using, save it to a file, and then have openldap use that file for the trust that it needs so that I do not need to adjust the variable from request to never? I do not have access to the AD domain controller and as a result cannot export the certificate. If there is a way to obtain the certificate from the command line, what commands do I need to use? Is there an alternate method of handling this issue that would be better in the long run? I have some CentOS servers and some Ubuntu servers that I am working with to try and get this going on. Thanks in advance for your help and ideas.

• Apache2 doesn't serve PHP-scripts correctly

  - by cmbrnt

  I've run into a problem with my Apache 2.2.16 configuration, running on Debian Squeeze. The problem is that it stopped serving PHP5-scripts completely. When I try to access the sites with Google Chrome, it instead downloads a file called "download", which contains the contents of the script. This is of course not a good thing. It does serve common html-files perfectly... I've been at this for quite a while now, and after all the googling and troubleshooting, I thought it would be a good time to ask you guys. Here's what I've got: The php5 and libapache2-mod-php5 packages are installed /etc/apache2/mods-available contains both php5.load and php5.conf, and these are symlinked from the mods-enabled directory The /etc/php5/ directory is left untouched since the installation. Here's the contents of /etc/apache2/mods-available/php.load: LoadModule php5_module /usr/lib/apache2/modules/libphp5.so And /etc/apache2/mods-available/php.conf: <IfModule mod_php5.c> <FilesMatch "\.ph(p3?|tml)$"> SetHandler application/x-httpd-php </FilesMatch> <FilesMatch "\.phps$"> SetHandler application/x-httpd-php-source </FilesMatch> <IfModule mod_userdir.c> <Directory /home/*/public_html> php_admin_value engine Off </Directory> </IfModule> </IfModule> What am I missing? This is a server with modified virtual hosts and the like, so I might have changed some settings which causes this problem, but simply purging and reinstalling is not an option so far, since the configuration is quite extensive. Any help would be great. Thanks.

• SQL Server performance on VSphere 4.0

  - by Charles

  We are having a performance issue that we cannot explain with our VMWare environment and I am hoping someone here may be able to help. We have a web application that uses a databases backend. We have an SQL 2005 Cluster setup on Windows 2003 R2 between a physical node and a virtual node. Both physical servers are identical 2950's with 2x Xeaon x5460 Quad Core CPUs and 64GB of memory, 16GB allocated to the OS. We are utilizing an iSCSI San for all cluster disks. The problem is this, when utilizing the application under a repeated stress testing that adds CPUs to the cluster nodes, the Physical node scales from 1 pCPU to 8 pCPUs, meaning we see continued performance increases. When testing the node running Vsphere, we have the expected 12% performance hit for being virtual but we still scale from 1 vCPU to 4 vCPUs like the physical but beyond this performance drops off, by the time we get to 8 vCPUs we are seeing performance numbers worse than at 4 vCPUs. Again, both nodes are configured identically in terms of hardware, Guest OS, SQL Configurations etc and there is no traffic other than the testing on the system. There are no other VMs on the virtual server so there should be no competition for resources. We have contacted VMWare for help but they have not really been any suggesting things like setting SQL Processor Affinity which, while being helpful would have the same net effect on each box and should not change our results in the least. We have looked at all of VMWare's SQL Tuning guides with regards to VSphere with no benefit, please help!

• AWS: Multi-region setup using single RDS instance

  - by Ion

  I'm trying to scale our web application (PHP, MySQL, memcache) in a multi-region scheme. Currently we are using a setup with two EC2 instances behind an ELB and an RDS instance, all of them in US-EAST (Virginia) region. We would like to have a presence in the EU (Ireland) region as well. This means at least a new EC2 instance there (identical to the others, serving the same application). I have copied the desired AMI, setup the new instance, setup a same ELB configuration (required for SSL termination) and configured latency-based routing in Route53. And it works as suggested. But, clients from EU have speed problems. This is due to the fact that the EU EC2 instances connect to the US-based RDS instance. As far as I know Amazon has not yet enabled RDS multi-region replication. Do you have any suggestions on how to properly speed up the whole setup while using the single RDS instance? Also, any ideas in general on how to scale things up? Ideally we would like to continue using the RDS technology for various reasons. Nevertheless, I am open to suggestions (I guess the next idea would be to host our own MySQL servers).
