• MaxClients in apache. How to know the size of my proccess?

  - by Larry

  From http://httpd.apache.org/docs/2.2/misc/perf-tuning.html The single biggest hardware issue affecting webserver performance is RAM. A webserver should never ever have to swap, as swapping increases the latency of each request beyond a point that users consider "fast enough". This causes users to hit stop and reload, further increasing the load. You can, and should, control the MaxClients setting so that your server does not spawn so many children it starts swapping. This procedure for doing this is simple: determine the size of your average Apache process, by looking at your process list via a tool such as top, and divide this into your total available memory, leaving some room for other processes. The main issue is that I can't understand how to know the size, because, well i have the size of httpd on no more of 3888 But, if we need to determine the number for MaxClients, and I have 4GB of RAM, so I get: 972, so I should use like 900 in the MaxClients?

• Apache VirtualHost running very slow on OS X 10.7 (Lion)

  - by jwerre

  I've set up a few virtual hosts in Lion and it's running very slowly. NameVirtualHost *:80 <VirtualHost *:80> ServerName localhost DocumentRoot "/Library/WebServer/Documents" </VirtualHost> <VirtualHost *:80> ServerName dev.local DocumentRoot "/Users/me/mysite" <Directory /Users/me/mysite> Order allow,deny Allow from all </Directory> </VirtualHost> then in /etc/hosts I added 127.0.0.1 dev.local Everything works fine but it's sooooo slow — 5 or so second to reload a simple "Hello World" html page. Here's is the strange part. If I make a symbolic link of the site in my ~/Sites folder (ln -s ~/mysite ~/Sites/mysite) and navigate to http://localhost/~me/mysite It's nice and fast the way it should be.

• Web authentication using LDAP and Apache?

  - by Stephen R

  I am working on a project of setting up a web administered inventory database for my work (or if they don't want it then i'll enjoy learning about it) and hit the problem of allowing only authorized users to access the website (In its testing/development phase, I allow all people to navigate to the website to add entries to the database and query it). I am trying to make it so only particular users in the domain (Active Directory) are allowed to access the website after they are queried about their credentials. I read that Apache (I am using a LAMP server) has a means of asking visitors to the website to provide LDAP credentials in order to gain access to the site, but I wasn't sure if that was exactly what I was looking for. If anyone has experience in the LDAP configurations for Apache that I mentioned or any other means of securely authenticating with websites I would greatly appreciate advice or a direction to go Thank you!

• Linking a facebook app's page to an existing facebook business page

  - by Dan

  I have a facebook app page, and a separate facebook business profile page. The business page was created, but not by me, some time before the app and its page were created. Is there any way to connect the two pages, or import the content and friends from one to the other? The older profile page has some content; a set of friends and wall posts that I don't want to lose. It was created before I had a chance to set up an app page. Since the app was created more recently, it does not have any content posted to it. I intended the app page to eventually hold some advertising info for my main website itself (non-canvas, just using fb for the connect api etc). The idea being that as people sign up on my site through facebook's OAuth, I could use the graph api to post to their wall. The wall posts are working as expected but naturally they are directing users to the facebook app page, which has no content, friends etc. I'd prefer to be directed to the original business page, where the party is really happening. Now it seems that the two pages are completely separate; what would I need to do to direct the users to the business page?

• Difference between Admin and Manager role in Tomcat6

  - by Nyxynyx

  What are the roles admin and manager used for in Tomcat6? The manager role appears to give me access to http://domain.com:8080/manager/html. Which page does the admin role give me? In the file, the description for admin role is pretty vague. What is the host manager webapp? <!-- The host manager webapp is restricted to users with role "admin" --> <!--<user name="tomcat" password="password" roles="admin" />--> <!-- The manager webapp is restricted to users with role "manager" --> <!--<user name="tomcat" password="password" roles="manager" />-->

• How do I objectively measure an application's load on a server

  - by Joe

  All, I'm not even sure where to begin looking for resources to answer my question, and I realize that speculation about this kind of thing is highly subjective. I need help determining what class of server I should purchase to host a MS Silverlight application with a MSSQL server back-end on a Windows Server 2008 platform. It's an interactive program, so I can't simply generate a list of URLs to test against, and run it with 1000 simultaneous users. What tools are out there to help me determine what kind of load the application will put on a server at varying levels of concurrent users? Would you all suggest separating the SQL server form the web server, to better differentiate the generated load on the different parts of the stack?

• Application Lifecycle Management Tools

  - by John K. Hines

  Leading a team comprised of three former teams means that we have three of everything.  Three places to gather requirements, three (actually eight or nine) places for customers to submit support requests, three places to plan and track work. We’ve been looking into tools that combine these features into a single product.  Not just Agile planning tools, but those that allow us to look in a single place for requirements, work items, and reports. One of the interesting choices is Software Planner by Automated QA (the makers of Test Complete).  It's a lovely tool with real end-to-end process support.  We’re probably not going to use it for one reason – cost.  I’m sure our company could get a discount, but it’s on a concurrent user license that isn’t cheap for a large number of users.  Some initial guesswork had us paying over $6,000 for 3 concurrent users just to get started with the Enterprise version.  Still, it’s intuitive, has great Agile capabilities, and has a reputation for excellent customer support. At the moment we’re digging deeper into Rational Team Concert by IBM.  Reading the docs on this product makes me want to submit my resume to Big Blue.  Not only does RTC integrate everything we need, but it’s free for up to 10 developers.  It has beautiful support for all phases of Scrum.  We’re going to bring the sales representative in for a demo. This marks one of the few times that we’re trying to resist the temptation to write our own tool.  And I think this is the first time that something so complex may actually be capably provided by an external source.   Hooray for less work!

• Entering new user data into AD LDS

  - by Robert Koritnik

  I need some help configuring AD LDS (Active Directory Lightweight Directory Services). I'm not an administrator, have never configured domains and I don't have a clue how to add new users to existing domains. The thing is I need to develop an app on top of Sharepoint 2010 that must be connected to AD. I've chosen AD LDS because I can install it on Windows 7 and it acts as an active directory even though there's no domain controller present in the network. What I've done so far: I've installed AD LDS I've added a new instance with appication directory partition name DN=Air,DC=Watanabe,DC=pri I can connect to it using ADSI Edit and see all kinds of strange But now I don't know what to do? When it opens I can see the window below, but where's next? Can anybody give me some guidelines, how can I add domain users, so I can use them in my app AD required app?

• Recommendation on Ticket system with billing feature

  - by jacklty

  Actually, I do not know if I have used the right terms to describe our situation. Basically, We would like to have a system to help us to do billing and support at the same time. For example, we would like to offer outside users a customer support with ticket system, however the outside users need to purchase some credits beforehand through the system in order to submit their requests. Sometimes, our representatives will charge extra unit of credit for solving some open tickets due to the complexity and hours spent. (It will be nice to submit user a further billing request to same open ticket, and user can either accept/declined) Is there any available application or service we can use for the purpose above?

• How should I copy the "mysql" database to my new server using PHPMyAdmin

  - by undefined

  My new webhosting company has set up a MySQL database for me and it has the tables MySQL and Information_schema already there. I want to copy my existing database from another server (a) to the new one (b). I assume I need to overwrite the 'mysql' database on server (b) with the one from my existing server (a) or atleast copy over the permissions. 1) What information does the mysql database hold? users and permissions I can see, does it have the login info for phpMyAdmin? I dont want to overwrite that obviously. 2) Should I drop the table on server (b) and import my original? 3) Should I just copy the users table? 4) Do I need to worry about the information_schema table? should I copy this over too? thanks

• Setting Mercurial with Active Directory authentication and authorisation

  - by jbx

  I am evaluating the possibilities of moving my organisation to Mercurial, however I am stumbling on 2 basic requirements which I can't find proper pointers to. How do I set up Mercurial's central repository to authenticate users with the central active directory and only allow them to push or pull if they have the right credentials? How do I set up a Mercurial project repository to only allow users pertaining to a specific group to push / pull source code? We need this to have per-project authorisation. On which HTTP servers (IIS or Apache etc.) are the above 2 requirements supported? Apologies if I am asking something obvious or if I am missing something fundamental about how authentication and authorisation works. Thanks.

• Windows 7 User / Documents and Settings folders

  - by Kip

  Yo, I have a machine - Windows 7, nothing remarkable about the install but i have multiple drives in the machine. I have a c:\users\username folder which seems to be current and is the one that all windows properties point to. However, i also have a f:\documents and settings\username folder (which was hidden) which is also current and up to date. If i edit anything from either, they seem to "replicate" or update each other ie if i rename an icon on my desktop, it renames it in c:\users\username\desktop and f:\documents and settings\username\desktop. Likewise if i edit directly in one of those folders, it does the same to the other. Any one got any ideas what might cause this? Problem i have is that I need to remove the f drive all together! Thanks in advance

• Enterprise user management

  - by Eduardo

  I am looking for an enterprise user management system that meets these requirements: Delegated user administration: The group manager should be able to grant access to his supervised employees (without having to contact any administrator either to grant access or maybe create users). A group manager should be able to create other groups and restrict any permission he already has where he can add supervised employees. If a manager removes access to a supervised group, then all the subgroups will also lose access. Web based User Interface. LDAP interface to query users and groups (or may not exist at all if it is integrated in a single application). Do you know if there are any system that meet these requirements?

• Something very strange with network

  - by Rodnower

  Hello, I have Windows 7 and I have very strange thing with my network. Some time I was connected through wireless router and my IP was 192.168.2.103, router's IP was 192.168.2.1 and some other IP was 192.168.2.100. The last I get from page "active DHCP clients" of web interface of the router and from "wireless clients" I may to see that 192.168.2.100 not (!) belong to my MAC address. Router build by EDimax. So after that I disabled wireless function of the router and restarted it. In this time I had not ping to 192.168.2.1. Also I had not any other connection, not wireless nor cable, but (!)

• Plesk 10 Postfix with multiple IP adresses and SSL certificates

  - by JulianB

  We are currently running a root server with Debian 6 and Plesk 10.4.4. We have some virtual hosts using one IP adress (shared) - e.g. example1.com - and another virtual host using a dedicated IP address (example2.com). Is there a way to configure postfix to do the following Always use the IP address of the virtual host to which the e-mail account belongs (so that an e-mail from [email protected] will originate from the shared IP-Address and an e-mail from [email protected] will originate from the dedicated IP? Use different certificates for TLS for example1.com and example2.com? If the latter is not possible: Could any problems arrive when using example1.com as certificate for example2.com users? Of course, example2.com users would have to configure their clients to use example1.com as the SMTP server name to avoid annoying security warnings. But if we still would be able to get the effect of the first point that would still be acceptable.

  I am working on a PHP laravel project. I am currently facing issues with .htaccess file. I have following .htaccess: <IfModule mod_rewrite.c> Options -MultiViews RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^ index.php [L] </IfModule> When I reload my page the it gave me following error: 404 Not Found The requested URL /contacts was not found on this server. Then I opened /etc/apache2/users/username.conf file which had following line of code: <Directory "/Users/username/Sites/"> Options Indexes MultiViews AllowOverride None Order allow,deny Allow from all </Directory> In above code I changed AllowOverride None to AllowOverride All. Then I reload page and got following error: 403 Forbidden You don't have permission to access /contacts on this server. When I add FollowSymLinks to .htaccess file Options such as like this Options -MultiViews FollowSymLinks. Then sometimes I get this 500 Internal Server Error error and sometime this *Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data*. Each time I reload my page one of these errors with FollowSymLinks option. I also uncomment following lines in /etc/apache2/httpd.conf: LoadModule rewrite_module libexec/apache2/mod_rewrite.so LoadModule php5_module libexec/apache2/libphp5.so and still I am getting same permission denied error. Please help me I am trying to solve this problem for past 3 days but it is till unresolved.

• Password Management for Oracle WebLogic customers

  - by Anthony Shorten

  One of the most common requests for enhancements I get across my desk is that customers wish to allow end users to change their passwords from our products. Now, typically password management is not in the realm of individual applications but it is an infrastructure requirement, so we don't usually add this to our roadmaps by default. The issue is that with the vast range of security stores that can be used with our product line across the Web Application Servers we support, it is almost impossible to come up with a generic enough API to work across them. If you have a specific security store on a specific Web Application Server platform then there are simpler solutions. There are a number of ways of implementing this without providing functionality specific functionality: Oracle sells Identity Management software that offers common API's to manage passwords. You can purchase those products and link to the password change dialog in those products using Navigation Keys. If you are a customer using Oracle WebLogic, then there is a sample JSP's that can be linked to provide this functionality under Oracle TechNet (registration required) under Code Samples (project S20). These can be added as a Navigation Key to complete the functionality. This will allow end users to manage their own passwords. Obviously these are all samples and should be treated as customizations when you implement them. If you wish to understand Navigation Keys, then look at the Oracle Utilities Application Framework Integration Guidelines (Doc Id: 789060.1) available from My Oracle Support.

• Is Joel Test really a good gauging tool?

  - by henry

  I just learned about Joel Test. I have been computer programmer for 22 years, but somehow never heard about it before. I consider my best job so far to be this small investment managing company with 30 employees and only 3 people in IT department. I am no longer with them but I had being working there for 5 years – my longest streak with any given company. To my surprise they scored extremely poor on Joel Test. The only two questions I would answer “yes” are #4: Do you have a bug database? And #9: Do you use the best tools money can buy? Everything else is either “sometimes” or straight “no”. Here is what I liked about the company however: a) Good pay, they bragged about it to my face and I bragged about it to their face, so it was almost like a family environment. b) I always knew big picture. When writing a code to solve particular problem there were no ambiguity about the business nature of that problem. Even though we did not always had written specs we could ask business users a question anytime, often yelling it across the floor. I could even talk to executives any time I felt like doing it: no appointment necessary. c) Immediate feedback. Once we implement a solution and make business users happy they immediately let us know that, we (programmers) become heroes of the moment. d) No red tape. I could always buy any tools I deem necessary, and design solutions the way my professional judgment dictates. e) Flexibility. If I had mid-day dental appointment that is near my house rather than near the office, I would send email to the company: "FYI: I work from home today". As long as one of 3 IT guys was on the floor (to help traders in case their monitors go dark) they did not care where 2 others are. So the question thus becomes how valuable Joel Test is? Why bother with it?

• What is the value in hiding the details through abstractions? Isn't there value in transparency?

  - by user606723

  Background I am not a big fan of abstraction. I will admit that one can benefit from adaptability, portability and re-usability of interfaces etc. There is real benefit there, and I don't wish to question that, so let's ignore it. There is the other major "benefit" of abstraction, which is to hide implementation logic and details from users of this abstraction. The argument is that you don't need to know the details, and that one should concentrate on their own logic at this point. Makes sense in theory. However, whenever I've been maintaining large enterprise applications, I always need to know more details. It becomes a huge hassle digging deeper and deeper into the abstraction at every turn just to find out exactly what something does; i.e. having to do "open declaration" about 12 times before finding the stored procedure used. This 'hide the details' mentality seems to just get in the way. I'm always wishing for more transparent interfaces and less abstraction. I can read high level source code and know what it does, but I'll never know how it does it, when how it does it, is what I really need to know. What's going on here? Has every system I've ever worked on just been badly designed (from this perspective at least)? My philosophy When I develop software, I feel like I try to follow a philosophy I feel is closely related to the ArchLinux philosophy: Arch Linux retains the inherent complexities of a GNU/Linux system, while keeping them well organized and transparent. Arch Linux developers and users believe that trying to hide the complexities of a system actually results in an even more complex system, and is therefore to be avoided. And therefore, I never try to hide complexity of my software behind abstraction layers. I try to abuse abstraction, not become a slave to it. Question at heart Is there real value in hiding the details? Aren't we sacrificing transparency? Isn't this transparency valuable?

• The emergence of Atlassian's Bamboo (and a free SQL Source Control license offer!)

  - by David Atkinson

  The rise in demand for database continuous integration has forced me to skill-up in various new tools and technologies, particularly build servers. We have been using JetBrain's TeamCity here at Red Gate for a couple of years now, having replaced the ageing CruiseControl.NET, so it was a natural choice for us to use this for our database CI demos. Most of our early adopter customers have also transitioned away from CruiseControl, the majority to TeamCity and Microsoft's TeamBuild. However, more recently, for reasons we've yet to fully comprehend, we've observed a significant surge in the number of evaluators for Atlassian's Bamboo. I installed this a couple of weeks back to satisfy myself that it works seamlessly with Red Gate tools. As you would expect Bamboo's UI has the same clean feel found in any Atlassian tool (we use JIRA extensively here at Red Gate). In the coming weeks I will post a short step-by-step guide to setting up SQL Server continuous integration using the Red Gate command lines. To help us further optimize the integration between these tools I'd be very keen to hear from any Bamboo users who also use Red Gate tools who might be willing to participate in usability tests and other similar research in exchange for Amazon vouchers. If you are interested in helping out please contact me at David dot Atkinson at red-gate.com I recently spoke with Sarah, the product marketing manager for Bamboo, and we ended up having a detailed conversation about database CI, which has been meticulously documented in the form of a blog post on Atlassian's website: http://blogs.atlassian.com/2012/05/database-continuous-integration-redgate/ We've also managed to persuade Red Gate marketing to provide a great free-tool offer, provide a free SQL Source Control or SQL Connect license to Atlassian users provided it is claimed before the end of June! Full details are at the bottom of the post. Technorati Tags: sql server
