• Localhost not working after installing PHP on Mountain Lion

  - by zen

  I've installed php using brew install php54 --with-mysql, I've set up all the path correctly. which php will give me /usr/local/bin/php php -v will give me PHP 5.4.8 (cli) (built: Nov 20 2012 09:29:31) php --ini will give me: Configuration File (php.ini) Path: /usr/local/etc/php/5.4 Loaded Configuration File: /usr/local/etc/php/5.4/php.ini Scan for additional .ini files in: /usr/local/etc/php/5.4/conf.d Additional .ini files parsed: (none) apachectl -V | grep httpd.conf will give me -D SERVER_CONFIG_FILE="/private/etc/apache2/httpd.conf" I believe everything is correct, but after I restarted my apache I keep getting error Service Temporarily Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later. This is my httpd.conf file: # # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/2.2> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do.

You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "log/foo_log" # with ServerRoot set to "/usr" will be interpreted by the # server as "/usr/log/foo_log". # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path.

• Capistrano asks for SSH password when deploying from local machine to server

  - by GhostRider

  When I try to ssh to a server, I'm able to do it as my id_rsa.pub key is added to the authorized keys in the server. Now when I try to deploy my code via Capistrano to the server from my local project folder, the server asks for a password. I'm unable to understand what could be the issue if I'm able to ssh and unable to deploy to the same server. $ cap deploy:setup "no seed data" triggering start callbacks for `deploy:setup' * 13:42:18 == Currently executing `multistage:ensure' *** Defaulting to `development' * 13:42:18 == Currently executing `development' * 13:42:18 == Currently executing `deploy:setup' triggering before callbacks for `deploy:setup' * 13:42:18 == Currently executing `db:configure_mongoid' * executing "mkdir -p /home/deploy/apps/development/flyingbird/shared/config" servers: ["dev1.noob.com", "176.9.24.217"] Password: Cap script: # gem install capistrano capistrano-ext capistrano_colors begin; require 'capistrano_colors'; rescue LoadError; end require "bundler/capistrano" # RVM bootstrap # $:.unshift(File.expand_path('./lib', ENV['rvm_path'])) require 'rvm/capistrano' set :rvm_ruby_string, 'ruby-1.9.2-p290' set :rvm_type, :user # or :user # Application setup default_run_options[:pty] = true # allow pseudo-terminals ssh_options[:forward_agent] = true # forward SSH keys (this will use your SSH key to get the code from git repository) ssh_options[:port] = 22 set :ip, "dev1.noob.com" set :application, "flyingbird" set :repository, "repo-path" set :scm, :git set :branch, fetch(:branch, "master") set :deploy_via, :remote_cache set :rails_env, "production" set :use_sudo, false set :scm_username, "user" set :user, "user1" set(:database_username) { application } set(:production_database) { application + "_production" } set(:staging_database) { application + "_staging" } set(:development_database) { application + "_development" } role :web, ip # Your HTTP server, Apache/etc role :app, ip # This may be the same as your `Web` server role :db, ip, :primary => true # This is where Rails migrations will run # Use multi-staging require "capistrano/ext/multistage" set :stages, ["development", "staging", "production"] set :default_stage, rails_env before "deploy:setup", "db:configure_mongoid" # Uncomment if you use any of these databases after "deploy:update_code", "db:symlink_mongoid" after "deploy:update_code", "uploads:configure_shared" after "uploads:configure_shared", "uploads:symlink" after 'deploy:update_code', 'bundler:symlink_bundled_gems' after 'deploy:update_code', 'bundler:install' after "deploy:update_code", "rvm:trust_rvmrc" # Use this to update crontab if you use 'whenever' gem # after "deploy:symlink", "deploy:update_crontab" if ARGV.include?("seed_data") after "deploy", "db:seed" else p "no seed data" end #Custom tasks to handle resque and redis restart before "deploy", "deploy:stop_workers" after "deploy", "deploy:restart_redis" after "deploy", "deploy:start_workers" after "deploy", "deploy:cleanup" 'Create symlink for public uploads' namespace :uploads do task :symlink do run <<-CMD rm -rf #{release_path}/public/uploads && mkdir -p #{release_path}/public && ln -nfs #{shared_path}/public/uploads #{release_path}/public/uploads CMD end task :configure_shared do run "mkdir -p #{shared_path}/public" run "mkdir -p #{shared_path}/public/uploads" end end namespace :rvm do desc 'Trust rvmrc file' task :trust_rvmrc do run "rvm rvmrc trust #{current_release}" end end namespace :db do desc "Create mongoid.yml in shared path" task :configure_mongoid do db_config = <<-EOF defaults: &defaults host: localhost production: <<: *defaults database: #{production_database} staging: <<: *defaults database: #{staging_database} EOF run "mkdir -p #{shared_path}/config" put db_config, "#{shared_path}/config/mongoid.yml" end desc "Make symlink for mongoid.yml" task :symlink_mongoid do run "ln -nfs #{shared_path}/config/mongoid.yml #{release_path}/config/mongoid.yml" end desc "Fill the database with seed data" task :seed do run "cd #{current_path}; RAILS_ENV=#{default_stage} bundle exec rake db:seed" end end namespace :bundler do desc "Symlink bundled gems on each release" task :symlink_bundled_gems, :roles => :app do run "mkdir -p #{shared_path}/bundled_gems" run "ln -nfs #{shared_path}/bundled_gems #{release_path}/vendor/bundle" end desc "Install bundled gems " task :install, :roles => :app do run "cd #{release_path} && bundle install --deployment" end end namespace :deploy do task :start, :roles => :app do run "touch #{current_path}/tmp/restart.txt" end desc "Restart the app" task :restart, :roles => :app do run "touch #{current_path}/tmp/restart.txt" end desc "Start the workers" task :stop_workers do run "cd #{current_path}; RAILS_ENV=#{default_stage} bundle exec rake resque:stop_workers" end desc "Restart Redis server" task :restart_redis do "/etc/init.d/redis-server restart" end desc "Start the workers" task :start_workers do run "cd #{current_path}; RAILS_ENV=#{default_stage} bundle exec rake resque:start_workers" end end

• Vagrant (Virtualbox) host-only multiple node networking issue

  - by Lorin Hochstein

  I'm trying to use a multi-VM vagrant environment as a testbed for deploying OpenStack, and I've run into a networking problem with trying to communicate from one VM, to a VM-inside-of-a-VM. I have two Vagrant nodes, a cloud controller node and a compute node. I'm using host-only networking. My Vagrantfile looks like this: Vagrant::Config.run do |config| config.vm.box = "precise64" config.vm.define :controller do |controller_config| controller_config.vm.network :hostonly, "192.168.206.130" # eth1 controller_config.vm.network :hostonly, "192.168.100.130" # eth2 controller_config.vm.host_name = "controller" end config.vm.define :compute1 do |compute1_config| compute1_config.vm.network :hostonly, "192.168.206.131" # eth1 compute1_config.vm.network :hostonly, "192.168.100.131" # eth2 compute1_config.vm.host_name = "compute1" compute1_config.vm.customize ["modifyvm", :id, "--memory", 1024] end end When I try to start up a (QEMU-based) VM, it boots successfully on compute1, and its virtual nic (vnet0) is connected via a bridge, br100: root@compute1:~# brctl show 100 bridge name bridge id STP enabled interfaces br100 8000.08002798c6ef no eth2 vnet0 When the QEMU VM makes a request to the DHCP server (dnsmasq) running on controller, I can see the request reaches the controller because of the output on the syslog on the controller: Aug 6 02:34:56 precise64 dnsmasq-dhcp[12042]: DHCPDISCOVER(br100) fa:16:3e:07:98:11 Aug 6 02:34:56 precise64 dnsmasq-dhcp[12042]: DHCPOFFER(br100) 192.168.100.2 fa:16:3e:07:98:11 However, the DHCPOFFER never makes it back to the VM running on compute1.

• phpmyadmin login redirect fails with custom ssl port

  - by baraboom

  The server is running Ubuntu 10.10, Apache 2.2.16, PHP 5.3.3-1ubuntu9.3, phpMyAdmin 3.3.7deb5build0.10.10.1. Since this same server is also running Zimbra on port 443, I've configured apache to serve SSL on port 81. So far, I have one CMS script running on this virtual host successfully. However, when I access /phpmyadmin (set up with the default alias) on my custom ssl port and submit the login form, I am redirected to http://vhost.domain.com:81/index.php?TOKEN=foo (note the http:// instead of the https:// that the login url was using). This generates an Error 400 Bad Request complaining about "speaking plain HTTP to an SSL-enabled server port." I can then manually change the http:// to https:// in the URL and use phpmyadmin as expected. I was annoyed enough to spend an hour trying to fix it and now even more annoyed that I cannot figure it out. I've tried various things, including: Adding $cfg['PmaAbsoluteUri'] = 'https://vhost.domain.com:81/phpmyadmin/'; to the /usr/share/phpmyadmin/config.inc.php file but this did not correct the problem (even though /usr/share/phpmyadmin/libraries/auth/cookie.auth.lib.php looks like it should honor it and use it as the redirect). Adding $cfg['ForceSSL'] = 1; to the same config.inc.php but then apache spirals into an infinite redirect. Adding a rewrite rule to the vhost-ssl conf file in apache but I was unable to figure out the condition to use when http:// was present along with the correct ssl port of :81. Lots of googling. Here are the relevant Apache configuration pieces: /etc/apache2/ports.conf <IfModule mod_ssl.c> NameVirtualHost *:81 Listen 81 </IfModule> /etc/apache2/sites-enabled/vhost-nonssl <VirtualHost *:80> ServerAdmin webmaster@localhost ServerName vhost.domain.com DocumentRoot /home/xxx/sites/vhost/html RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}:81%{REQUEST_URI} </Virtualhost> /etc/apache2/sites-enabled/vhost-ssl <VirtualHost *:81> ServerAdmin webmaster@localhost ServerName vhost.domain.com DocumentRoot /home/xxx/sites/vhost/html <Directory /> Options FollowSymLinks AllowOverride None AuthType Basic AuthName "Restricted Vhost" AuthUserFile /home/xxx/sites/vhost/.users Require valid-user </Directory> <Directory /home/xxx/sites/vhost/html/> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> /etc/apache2/conf.d/phpmyadmin.conf Alias /phpmyadmin /usr/share/phpmyadmin (The rest of the default .conf truncated.) Everything in the apache config seems to work ok - the rewrite from non-ssl to ssl, the http authentication, the problem only happens when I am submitting the login form for phpmyadmin from https://vhost.domain.com:81/index.php. Other configs: The phpmyadmin config is completely default and the php.ini has only had some minor changes to memory and timeout limits. These seem to work fine, as mentioned, another php script runs with no problem and phpmyadmin works great once I manually enter in the correct schema after login. I'm looking for either a bandaid I can add to save me the trouble of manually entering in the https:// after login, a real fix that will make phpmyadmin behave as I think it should or some greater understanding of why my desired config is not possible.

• PHP.ini does not load

  - by Jonathan Park

  Ok this is probably just me not knowing enough about php but here it goes. I'm on Ubuntu Hardy. I have a custom compiled version of PHP which I have compiled with these parameters. ./configure --enable-soap --with-zlib --with-mysql --with-apxs2=[correct path] --with-config-file-path=[correct path] --with-mysqli --with-curlwrappers --with-curl --with-mcrypt I have used the command pecl install pecl_http to install the http.so extension. It is in the correct module directory for my php.ini. My php.ini is loading and I can change things within the ini and effect php. I have included the extension=http.so line in my php.ini. That worked fine. Until I added these compilation options in order to add imap --with-openssl --with-kerberos --with-imap --with-imap-ssl Which failed because I needed the c-client library which I fixed by apt-get install libc-client-dev After which php compiles fine and I have working imap support, woo. HOWEVER, now all my calls to HttpRequest which is part of the pecl_http extention in http.so result in Fatal error: Class 'HttpRequest' not found errors. I figure the http.so module is no longer loading for one reason or another but I cannot find any errors showing the reason. You might say "Have you tried undoing the new imap setup?" To which I will answer. Yes I have. I directly undid all my config changes and uninstalled the c-client library and I still can't get it to work. I thought that's weird... I have made no changes that would have resulted in this issue. After looking at that I have also discovered that not only is the http extension no longer loading but all my extensions loaded via php.ini are no longer loading. Can someone at least give me some further debugging steps? So far I have tried enabling all errors including startup errors in my php.ini which works for other errors, but I'm not seeing any startup errors either on command line or via apache. And yet again the php.ini appears to be being parsed given that if I run php_info() I get settings that are in the php.ini. Edit it appears that only some of the php.ini settings are being listened to. Is there a way to test my php.ini? Edit Edit It appears I am mistaken again and the php.ini is not being loaded at all any longer. However, If I run php_info() I get that it's looking for my php.ini in the correct location. Edit Edit Edit My config is at the config file path location below but it says no config file loaded. WTF Permission issue? It is currently 644 so everyone should be able to read it if not write it. I tried making it 777 and that didn't work. Configuration File (php.ini) Path /etc/php.ini Loaded Configuration File (none) Edit Edit Edit Edit By loading the ini on the command line using the -c command I am able to run my files and using -m shows that my modules load So nothing is wrong with the php.ini

• Removing the XML Formatter from ASP.NET Web API Applications

  - by Rick Strahl

  ASP.NET Web API's default output format is supposed to be JSON, but when I access my Web APIs using the browser address bar I'm always seeing an XML result instead. When working on AJAX application I like to test many of my AJAX APIs with the browser while working on them. While I can't debug all requests this way, GET requests are easy to test in the browser especially if you have JSON viewing options set up in your various browsers. If I preview a Web API request in most browsers I get an XML response like this: Why is that? Web API checks the HTTP Accept headers of a request to determine what type of output it should return by looking for content typed that it has formatters registered for. This automatic negotiation is one of the great features of Web API because it makes it easy and transparent to request different kinds of output from the server. In the case of browsers it turns out that most send Accept headers that look like this (Chrome in this case): Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Web API inspects the entire list of headers from left to right (plus the quality/priority flag q=) and tries to find a media type that matches its list of supported media types in the list of formatters registered. In this case it matches application/xml to the Xml formatter and so that's what gets returned and displayed. To verify that Web API indeed defaults to JSON output by default you can open the request in Fiddler and pop it into the Request Composer, remove the application/xml header and see that the output returned comes back in JSON instead. An accept header like this: Accept: text/html,application/xhtml+xml,*/*;q=0.9 or leaving the Accept header out altogether should give you a JSON response. Interestingly enough Internet Explorer 9 also displays JSON because it doesn't include an application/xml Accept header: Accept: text/html, application/xhtml+xml, */* which for once actually seems more sensible. Removing the XML Formatter We can't easily change the browser Accept headers (actually you can by delving into the config but it's a bit of a hassle), so can we change the behavior on the server? When working on AJAX applications I tend to not be interested in XML results and I always want to see JSON results at least during development. Web API uses a collection of formatters and you can go through this list and remove the ones you don't want to use - in this case the XmlMediaTypeFormatter. To do this you can work with the HttpConfiguration object and the static GlobalConfiguration object used to configure it: protected void Application_Start(object sender, EventArgs e) { // Action based routing (used for RPC calls) RouteTable.Routes.MapHttpRoute( name: "StockApi", routeTemplate: "stocks/{action}/{symbol}", defaults: new { symbol = RouteParameter.Optional, controller = "StockApi" } ); // WebApi Configuration to hook up formatters and message handlers RegisterApis(GlobalConfiguration.Configuration); } public static void RegisterApis(HttpConfiguration config) { // remove default Xml handler var matches = config.Formatters .Where(f = f.SupportedMediaTypes .Where(m = m.MediaType.ToString() == "application/xml" || m.MediaType.ToString() == "text/xml") .Count() 0) .ToList() ; foreach (var match in matches) config.Formatters.Remove(match); } } That LINQ code is quite a mouthful of nested collections, but it does the trick to remove the formatter based on the content type. You can also look for the specific formatter (XmlMediatTypeFormatter) by its type name which is simpler, but it's better to search for the supported types as this will work even if there are other custom formatters added. Once removed, now the browser request results in a JSON response: It's a simple solution to a small debugging task that's made my life easier. Maybe you find it useful too…© Rick Strahl, West Wind Technologies, 2005-2012Posted in Web Api  ASP.NET   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• SQL SERVER – Attach mdf file without ldf file in Database

  - by pinaldave

  Background Story: One of my friends recently called up and asked me if I had spare time to look at his database and give him a performance tuning advice. Because I had some free time to help him out, I said yes. I asked him to send me the details of his database structure and sample data. He said that since his database is in a very early stage and is small as of the moment, so he told me that he would like me to have a complete database. My response to him was “Sure! In that case, take a backup of the database and send it to me. I will restore it into my computer and play with it.” He did send me his database; however, his method made me write this quick note here. Instead of taking a full backup of the database and sending it to me, he sent me only the .mdf (primary database file). In fact, I asked for a complete backup (I wanted to review file groups, files, as well as few other details).  Upon calling my friend,  I found that he was not available. Now,  he left me with only a .mdf file. As I had some extra time, I decided to checkout his database structure and get back to him regarding the full backup, whenever I can get in touch with him again. Technical Talk: If the database is shutdown gracefully and there was no abrupt shutdown (power outrages, pulling plugs to machines, machine crashes or any other reasons), it is possible (there’s no guarantee) to attach .mdf file only to the server. Please note that there can be many more reasons for a database that is not getting attached or restored. In my case, the database had a clean shutdown and there were no complex issues. I was able to recreate a transaction log file and attached the received .mdf file. There are multiple ways of doing this. I am listing all of them here. Before using any of them, please consult the Domain Expert in your company or industry. Also, never attempt this on live/production server without the presence of a Disaster Recovery expert. USE [master] GO -- Method 1: I use this method EXEC sp_attach_single_file_db @dbname='TestDb', @physname=N'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\TestDb.mdf' GO -- Method 2: CREATE DATABASE TestDb ON (FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\TestDb.mdf') FOR ATTACH_REBUILD_LOG GO Method 2: If one or more log files are missing, they are recreated again. There is one more method which I am demonstrating here but I have not used myself before. According to Book Online, it will work only if there is one log file that is missing. If there are more than one log files involved, all of them are required to undergo the same procedure. -- Method 3: CREATE DATABASE TestDb ON ( FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\TestDb.mdf') FOR ATTACH GO Please read the Book Online in depth and consult DR experts before working on the production server. In my case, the above syntax just worked fine as the database was clean when it was detached. Feel free to write your opinions and experiences for it will help the IT community to learn more from your suggestions and skills.

• Stream Media from Windows 7 to XP with VLC Media Player

  - by DigitalGeekery

  So you’ve got yourself a new computer with Windows 7 and you’re itching to take advantage of it’s ability to stream media across your home network. But, the rest of the family is still on Windows XP and you’re not quite ready to shell out the cash for the upgrades. Well, today we’ll show you how to easily stream media from Windows 7 to Windows XP with VLC Media Player. On the host computer running Windows 7, you’ll need to have an account set up with both a username and password. A blank password will not work. The media files will need to be located in a shared folder. Note: If the media files are located within the Public directory, or within the profile of the user account you use to log into the Windows 7 computer, they will be shared automatically. Sharing your Media Folders On your Windows 7 computer, right-click on the folder containing the files you’d like to stream and choose Properties.     On the Sharing Tab of the folder properties, click the Share button. Click OK.   Type or select from the drop down the user account you’ll use to log in, or select “Everyone” to share with all users. Then click Add. You may change the permission level, but only Read permission is required to play the media. Repeat this process for any additional folders you wish to share.    The Windows XP Client Computer Now that we’ve shared our media folders from the Windows 7 computer, we’re ready to play our files on the Windows XP computer. Download and install the VLC Media Player. (See link below) Then open VLC. Click on Media from the and select Open File… Browse your network for the shared folder that contains your media.   You’ll be prompted to log in to the host computer. Provide the credentials for a user on the Windows 7 computer. Click OK.   Select your media file and click Open.    Your media playback will begin momentarily.   This is a nice and easy way to stream media across your home network without upgrading multiple computers to Windows 7.  Plus, VLC is certainly no slouch as a Media Player.

• Tool to convert blogger.com content to dasBlog

  - by Daniel Moth

  Due to blogger.com dropping FTP support, I've had to move my blog. If you are in a similar situation, this post will help you by showing you the necessary steps to take. Goals No loss on blog posts, comments AND all existing permalinks continue to work (redirect to the correct place). Steps Download the XML files corresponding to your blogger.com content and store them in a folder. Install and configure dasBlog on your local machine. Configure your web.config file (will need updating once you run step 4). Use the tool I describe further down to generate the content and place it at the right place. Test your site locally. Once you are happy, repeat step 2 on your hosting provider of choice. Remember to copy up your dasBlog theme folder if you created one. Copy up the local web.config file and the XML dasBlog content files generated by the tool of step 4. Test your site on the server. Once you are happy, go live (following instructions from your hoster). In my case, I gave the nameservers from my new hoster to my existing domain registrar and they made the switch. Tool (code) At step 4 above I referred to a tool. That is an overstatement, it is simply one 450-line C#code file that you can download here: BloggerToDasBlog.cs. I used this from a .NET 2.0 console app (and I run it under the Visual Studio debugger, i.e. F5) like this: Program.cs. The console app referenced the dasBlog 2.3 ASP.NET Blogging Engine i.e. the newtelligence.DasBlog.Runtime.dll assembly. Let me describe what the code does: Input: A path to a folder where the XML files from the old blogger.com blog reside. It can deal with both types of XML file. A full file path to a file where it creates XML redirect input (as required by the rewriteMap mentioned here). The blog URL. The author's email. The blog author name. A path to an empty folder where the new XML dasBlog content files will get created. The subfolder name used after the domain name in the URL. The 3 reg ex patterns to use. You can use the same as mine, but will need to tweak the monthly_archive rule. Again, to see what values I passed for all the above, see my Program.cs file. Output: It creates dasBlog XML files in the folder specified. It creates those by parsing the old blogger.com XML files that reside in the folder specified. After that is generated, copy it to the "Content" folder under your dasBlog installation. It creates an XML file with a single ignorable root element and a bunch of inner XML elements. You can copy paste these in the web.config file as discussed in this post. Other notes: For each blog post, it detects outgoing links to itself (i.e. to the same blog), and rewrites those to point to the new URLs. So internal links do not rely on the web.config redirects. It deals with duplicate post titles; it does not deal with triplicates and higher. Removes all references to blogger.com (e.g. references to [email protected], the injected hidden footer for statistics that each blog post has and others – see the code). It creates a lot of diagnostic output (in the Output window) and indeed the documentation for the code is in the Debug.WriteLine statements ;) This is not code I will maintain or support – it was a throwaway one-use project that I am sharing here as a starting point for anyone finding themselves in the same boat that I was. Enjoy "as is". Comments about this post welcome at the original blog.

• Add the Vista Style Sidebar Back to Windows 7

  - by Mysticgeek

  If you are moving from Vista to Windows 7, you might miss the Sidebar which was introduced in Vista. Today we take a look at a couple options for getting a Sidebar back in Windows 7. Copy Files from Vista Note: In this example we are using 32-bit versions of Vista and Windows 7. Make sure you are logged in with Administrator credentials. If you have a Vista machine running, we can copy the Windows Sidebar files over to the Windows 7 machine. On the Vista machine navigate to C:\Program Files and copy the Windows Sidebar folder and all of its contents over to a flash drive or network location. On the Windows 7 machine go to C:\Program Files and rename the Windows Sidebar folder to something like Windows Sidebar_old. Now copy the Vista Windows Sidebar folder into C:\Program Files… Now you will have both folders…Windows Sidebar and Windows Sidebar_old in your C:\Program Files folder. Right-click on the desktop and select Gadgets. There you are…the Original Vista Sidebar is back and will act as it did in Vista. Move Sidebar Gadgets Another work around if you don’t have a copy of Vista, you can simply move the Desktop Gadgets you want over to the right side of the screen and they will stay there…no dock needed. Type gadgets into the Search box in the Windows Start Menu and click on Desktop Gadgets. Then drag the included Gadgets you want over to the right side of the screen. Or click on the link to Get more gadgets online to find more. Once you have them where you want, each time you reboot they will still be in the same location. This holds true no matter where you place them on your desktop as well. Install Desktop Sidebar If you want an enhanced sidebar that includes a lot of different features, and don’t have a copy of Vista, you might want to check out Desktop Sidebar Beta (link below). This is a freeware application that works with Windows XP, Vista, and Windows 7. After installation you can access it from the Start Menu… Here is how it will look after you launch it… It includes several pre-installed panels including a clock, Media Player, Search Bar, Slideshow, Messenger, Outlook inbox, Tasks, Quick Launch, Performance…and a lot more. It is highly customizable and allows you to change skins, add various levels of transparency, and a lot more. One caveat with going with Desktop Sidebar is we didn’t find a way to add Windows Gadgets to it (though there might be a plugin for it that we’re not aware of). But there are so many options, you may not mind. However, you can still use the desktop gadgets as you normally would in Windows 7. Believe it or not, some people actually prefer the Vista style Sidebar and would like it back in Windows 7. With these options you can get the Vista Sidebar back if you have a copy of Vista, place the Gadgets on the desktop, or go the freeware route.

• WSS 3.0/MOSS 2007 Active Directory Forms Based Authentication PeoplePicker no users found

  - by John Haigh

  WSS 3.0/MOSS 2007 Active Directory Forms Based Authentication PeoplePicker no users found After finding these steps online from http://dattard.blogspot.com/2008/11/active-directory-forms-based.html in order to setup Active Directory Forms Based Authentication I was all set to complete this task, except for one problem. These steps are missing one very important vital step in order for FBA to work with Active Directory. A supplement to step 3 before granting access in step 5 through the people picker. You need to specify the Active Directory Provider Name to the people picker, otherwise you will not be able specify users through the Policy for Web Application. <PeoplePickerWildcards>       <clear />          <add key="ADMembershipProvider" value="%" />     </PeoplePickerWildcards> Recently we needed to use Forms Based Authentication with Active Directory from an Extranet. This is how we got it to work. 1. Extend the Web Application Instead of tweaking the internal web app, Extend the web application you want to expose to the Extranet, giving it the required host headers etc. 2. Configure SharePoint Central Admin to use FBA for the "new" Web Applications Login to SharePoint Central Admin Go to Application Management / Application Security / Authentication Providers and Change the Web Application to the one which needs to be configured for Forms Based Authentication Click zone / default, change authentication type to forms and enter ActiveDirectoryMemebershipProvider under membership provider name ( for example , "ADMembershipProvider") and save this change 3. Update the web.config of SharePoint Central admin site under configuration node <connectionStrings> <add name="ADConnectionString" connectionString="LDAP://DynamicsAX.local/CN=Users,DC=DynamicsAX,DC=local /> </connectionStrings> under system.web node <membership defaultProvider="ADMembershipProvider"> <providers> <add name="ADMembershipProvider" type="System.Web.Security.ActiveDirectoryMembershipProvider,System.Web,Version=2.0.0.0,Culture=neutral,PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="ADConnectionString" connectionUsername="xxx" connectionPassword="yyy" enableSearchMethods="true" attributeMapUsername="sAMAccountName"/> </providers> </membership> 4.Update the web.config of SharePoint Web application Repeat step 3 for the web.config of the SharePoint webapplication to be configured for Forms Based Authentication Change the authentication in web.config to <authentication mode="Forms"> <forms loginUrl="/_layouts/login.aspx"></forms> </authentication> 5. Grant Access on the extended Web Application Your extranet web application is now configured to use FBA. However, until users, who will be accessing the site via FBA, are given permissions for the site, it will be inaccessible to them. To get started, open your browser and navigate to your farm’s Central Administration site. Click on Application Management and then click on Policy for Web Application. Make sure that you are working on the extranet web application. Do the following steps: Click on Add Users. In the Zones drop down, select the appropriate Extranet zone. IMPORTANT: If you select the incorrect zone, you may not be able to resolve user names. Hence, the zone you select must match the zone of the web application that is configured to use FBA. Click the Next button. In the Users edit box, type the name of the FBA user whom you wish to have full control for the site. Click the Resolve link next to the Users edit box. If the web application's FBA information has been configured correctly, the name will resolve and become underlined. Check the Full Control checkbox. Click the Finish button.

• OSB and Coherence Integration

  - by mark.ms.smith

  Anyone who has tried to manage Coherence nodes or tried to cache results in OSB, will appreciate the new functionality now available. As of WebLogic Server 10.3.4, you can use the WebLogic Administration Server, via the Administration Console or WLST, and java-based Node Manager to manage and monitor the life cycle of stand-alone Coherence cache servers. This is a great step forward as the previous options mainly involved writing your own scripts to do this. You can find an excellent description of how this works at James Bayer’s blog. You can also find the WebLogic documentation here.As of Oracle Service Bus 11gR1 (11.1.1.3.0), OSB now supports service result caching for Business Bervices with Coherence. If you use Business Services that return somewhat static results that do not change often, you can configure those Business Services to cache results. For Business Services that use result caching, you can control the time to live for the cached result. After the cached result expires, the next Business Service call results in invoking the back-end service to get the result. This result is then stored in the cache for future requests to access. I’m thinking that this caching functionality would be perfect for some sort of cross reference data that was refreshed nightly by batch. You can find the OSB Business Service documentation here.Result Caching in a dedicated JVMThis example demonstrates these new features by configuring a OSB Business Service to cache results in a separate Coherence JVM managed by WebLogic. The reason why you may want to use a separate, dedicated JVM is that the result cache data could potentially be quite large and you may want to protect your OSB java heap.In this example, the client will call an OSB Proxy Service to get Employee data based on an Employee Id. Using a Business Service, OSB calls an external system. The results are automatically cached and when called again, the respective results are retrieved from the cache rather than the external system.Step 1 – Set up your Coherence Server Via the OSB Administration Server Console, create your Coherence Server to be used as the results cache.Here are the configured Coherence Server arguments from the Server Start tab. Note that I’m using the default Cache Config and Override files in the domain.-Xms256m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=256m -Dtangosol.coherence.override=/app/middleware/jdev_11.1.1.4/user_projects/domains/osb_domain2/config/osb/coherence/osb-coherence-override.xml -Dtangosol.coherence.cluster=OSB-cluster -Dtangosol.coherence.cacheconfig=/app/middleware/jdev_11.1.1.4/user_projects/domains/osb_domain2/config/osb/coherence/osb-coherence-cache-config.xml -Dtangosol.coherence.distributed.localstorage=true -Dtangosol.coherence.management=all -Dtangosol.coherence.management.remote=true -Dcom.sun.management.jmxremote Just incase you need it, here is my Coherence Server classpath:/app/middleware/jdev_11.1.1.4/oracle_common/modules/oracle.coherence_3.6/coherence.jar: /app/middleware/jdev_11.1.1.4/modules/features/weblogic.server.modules.coherence.server_10.3.4.0.jar: /app/middleware/jdev_11.1.1.4/oracle_osb/lib/osb-coherence-client.jarBy default, OSB will try and create a local result cache instance. You need to disable this by adding the following JVM parameters to each of the OSB Managed Servers:-Dtangosol.coherence.distributed.localstorage=false -DOSB.coherence.cluster=OSB-clusterIf you need more information on configuring a remote result cache, have a look at the configuration documentration under the heading Using an Out-of-Process Coherence Cache Server.Step 2 – Configure your Business Service Under the respective Business Service Message Handling Configuration (Advanced Properties), you need to enable “Result Caching”. Additionally, you need to determine what the cache data will be keyed on. In the example below, I’m keying it on the unique Employee Id.The Results As this test was on my laptop, the actual timings are just an indication that there is a benefit to caching results. Using my test harness, I sent 10,000 requests to OSB, all with the same Employee Id. In this case, I had result caching disabled.You can see that this caused the back end Business Service (BS_GetEmployeeData) to be called for each request. Then after enabling result caching, I sent the same number of identical requests.You can now see the Business Service was only invoked once on the first request. All subsequent requests used the Results Cache.

• Oracle Big Data Software Downloads

  - by Mike.Hallett(at)Oracle-BI&EPM

  Companies have been making business decisions for decades based on transactional data stored in relational databases. Beyond that critical data, is a potential treasure trove of less structured data: weblogs, social media, email, sensors, and photographs that can be mined for useful information. Oracle offers a broad integrated portfolio of products to help you acquire and organize these diverse data sources and analyze them alongside your existing data to find new insights and capitalize on hidden relationships. Oracle Big Data Connectors Downloads here, includes: Oracle SQL Connector for Hadoop Distributed File System Release 2.1.0 Oracle Loader for Hadoop Release 2.1.0 Oracle Data Integrator Companion 11g Oracle R Connector for Hadoop v 2.1 Oracle Big Data Documentation The Oracle Big Data solution offers an integrated portfolio of products to help you organize and analyze your diverse data sources alongside your existing data to find new insights and capitalize on hidden relationships. Oracle Big Data, Release 2.2.0 - E41604_01 zip (27.4 MB) Integrated Software and Big Data Connectors User's Guide HTML PDF Oracle Data Integrator (ODI) Application Adapter for Hadoop Apache Hadoop is designed to handle and process data that is typically from data sources that are non-relational and data volumes that are beyond what is handled by relational databases. Typical processing in Hadoop includes data validation and transformations that are programmed as MapReduce jobs. Designing and implementing a MapReduce job usually requires expert programming knowledge. However, when you use Oracle Data Integrator with the Application Adapter for Hadoop, you do not need to write MapReduce jobs. Oracle Data Integrator uses Hive and the Hive Query Language (HiveQL), a SQL-like language for implementing MapReduce jobs. Employing familiar and easy-to-use tools and pre-configured knowledge modules (KMs), the application adapter provides the following capabilities: Loading data into Hadoop from the local file system and HDFS Performing validation and transformation of data within Hadoop Loading processed data from Hadoop to an Oracle database for further processing and generating reports Oracle Database Loader for Hadoop Oracle Loader for Hadoop is an efficient and high-performance loader for fast movement of data from a Hadoop cluster into a table in an Oracle database. It pre-partitions the data if necessary and transforms it into a database-ready format. Oracle Loader for Hadoop is a Java MapReduce application that balances the data across reducers to help maximize performance. Oracle R Connector for Hadoop Oracle R Connector for Hadoop is a collection of R packages that provide: Interfaces to work with Hive tables, the Apache Hadoop compute infrastructure, the local R environment, and Oracle database tables Predictive analytic techniques, written in R or Java as Hadoop MapReduce jobs, that can be applied to data in HDFS files You install and load this package as you would any other R package. Using simple R functions, you can perform tasks such as: Access and transform HDFS data using a Hive-enabled transparency layer Use the R language for writing mappers and reducers Copy data between R memory, the local file system, HDFS, Hive, and Oracle databases Schedule R programs to execute as Hadoop MapReduce jobs and return the results to any of those locations Oracle SQL Connector for Hadoop Distributed File System Using Oracle SQL Connector for HDFS, you can use an Oracle Database to access and analyze data residing in Hadoop in these formats: Data Pump files in HDFS Delimited text files in HDFS Hive tables For other file formats, such as JSON files, you can stage the input in Hive tables before using Oracle SQL Connector for HDFS. Oracle SQL Connector for HDFS uses external tables to provide Oracle Database with read access to Hive tables, and to delimited text files and Data Pump files in HDFS.

• No database selected error in CodeIgniter running on MAMP stack

  - by Apophenia Overload

  First off, does anyone know of a good place to get help with CodeIgniter? The official community forums are somewhat disappointing in terms of getting many responses. I have ci installed on a regular MAMP stack, and I’m working on this tutorial. However, I have only gone through the Created section, and currently I am getting a No database selected error. Model: <?php class submit_model extends Model { function submitForm($school, $district) { $data = array( 'school' => $school, 'district' => $district ); $this->db->insert('your_stats', $data); } } View: <?php $this->load->helper('form'); ?> <?php echo form_open('main'); ?> <p> <?php echo form_input('school'); ?> </p> <p> <?php echo form_input('district'); ?> </p> <p> <?php echo form_submit('submit', 'Submit'); ?> </p> <?php echo form_close(); ?> Controller: <?php class Main extends controller { function index() { // Check if form is submitted if ($this->input->post('submit')) { $school = $this->input->xss_clean($this->input->post('school')); $district = $this->input->xss_clean($this->input->post('district')); $this->load->model('submit_model'); // Add the post $this->submit_model->submitForm($school, $district); } $this->load->view('main_view'); } } database.php $db['default']['hostname'] = "localhost:8889"; $db['default']['username'] = "root"; $db['default']['password'] = "root"; $db['default']['database'] = "stats_test"; $db['default']['dbdriver'] = "mysql"; $db['default']['dbprefix'] = ""; $db['default']['pconnect'] = TRUE; $db['default']['db_debug'] = TRUE; $db['default']['cache_on'] = FALSE; $db['default']['cachedir'] = ""; $db['default']['char_set'] = "utf8"; $db['default']['dbcollat'] = "utf8_general_ci"; config.php $config['base_url'] = "http://localhost:8888/ci/"; ... $config['index_page'] = "index.php"; ... $config['uri_protocol'] = "AUTO"; So, how come it’s giving me this error message?

• Why is Apache ignoring VirtualHost directive for first name in hosts file?

  - by Peter Taylor

  Standard pre-emptive disclaimer: host names, IP addresses, and directories are anonymised. Problem We have a server with Apache 2.2 (WAMP) listening on one IP and IIS listening on another. An ASP.Net application running under IIS needs to do some simple GETs from the PHP applications running under Apache to build a unified search results page. This is a virtual server, so the internal IPs are mapped somehow to external ones. The internal DNS system doesn't resolve the publicly published names under which the applications are accessed externally, so the obvious solution was to add them to etc/hosts with the internal IP address: 127.0.0.1 localhost # 10.0.1.17 is the IP address Apache listens on 10.0.1.17 phpappone.example.com 10.0.1.17 phpapptwo.example.com After restarting Apache, phpappone.example.com stopped working. Instead of returning pages from that app, Apache was returning pages from the default site. The other PHP apps worked fine. Relevant configuration httpd.conf, summarised, says: ServerAdmin [email protected] ServerRoot "c:/server/Apache2" ServerName www.example.com Listen 10.0.1.17:80 Listen 10.0.1.17:443 # Not obviously related config options elided # Nothing obviously astandard # If you want more details, post a comment DocumentRoot "c:/server/Apache2/htdocs" <Directory /> Options FollowSymLinks AllowOverride None Order deny,allow Deny from all </Directory> # Fallback for unknown host names <Directory "c:/server/Apache2/htdocs"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> # PHP apps common config <Directory "C:/Inetpub/wwwroot/phpapps"> Options FollowSymLinks -Indexes +ExecCGI AllowOverride All Order Allow,Deny Allow from All </Directory> # Virtual hosts NameVirtualHost 10.0.1.17:80 NameVirtualHost 10.0.1.17:443 <VirtualHost _default_:80> </VirtualHost> <VirtualHost _default_:443> SSLEngine On SSLCertificateFile "certs/example.crt" SSLCertificateKeyFile "certs/example.key" </VirtualHost> Include conf/vhosts/*.conf and the vhosts files are e.g. <VirtualHost 10.0.1.17:80> ServerName phpappone.example.com DocumentRoot "c:/Inetpub/wwwroot/phpapps/phpappone" </VirtualHost> <VirtualHost 10.0.1.17:443> ServerName phpappone.example.com DocumentRoot "c:/Inetpub/wwwroot/phpapps/phpappone" SSLEngine On SSLCertificateFile "certs/example.crt" SSLCertificateKeyFile "certs/example.key" </VirtualHost> Buggy behaviour or our misunderstanding? The documentation for name-based virtual hosts says that Now when a request arrives, the server will first check if it is using an IP address that matches the NameVirtualHost. If it is, then it will look at each <VirtualHost> section with a matching IP address and try to find one where the ServerName or ServerAlias matches the requested hostname. If it finds one, then it uses the configuration for that server. If no matching virtual host is found, then the first listed virtual host that matches the IP address will be used. Yet that isn't what we observe. It seems that if the hostname is the first hostname listed against the IP address in etc/hosts then it uses the configuration from the main server and skips the virtual host lookup. Workarounds The workaround we've put in place for the time being is to add a fake line to the hosts file: 127.0.0.1 localhost # 10.0.1.17 is the IP address Apache listens on 10.0.1.17 fakename.example.com 10.0.1.17 phpappone.example.com 10.0.1.17 phpapptwo.example.com This fixes the problem, but it's not very elegant. In addition, it seems a bit brittle: reordering lines in the hosts file (or deleting the nonsense value) can break it. The other obvious workaround is to make the main server configuration match that of the troublesome virtual host, but that is equally brittle. A third option, which is just ugly, would be to change the ASP.Net code to take separate config items for the IP address and the hostname and to implement HTTP manually. Ugh. The question Is there a good solution to this problem which localises any "Do not touch this!" explanations to the Apache config files?

  The following snippets will helpful one who user version control systems like Git and SVN.svn checkout/co checkout-url – used to pull an SVN tree from the server.svn update/up – Used to update the local copy with the changes made in the repository.svn commit/ci – m “message” filename – Used to commit the changes in a file to repository with a message.svn diff filename – shows up the differences between your current file and what’s there now in the repository.svn revert filename – To overwrite local file with the one in the repository.svn add filename – For adding a file into repository, you should commit your changes then only it will reflect in repository.svn delete filename – For deleting a file from repository, you should commit your changes then only it will reflect in repository.svn move source destination – moves a file from one directory to another or renames a file. It will effect your local copy immediately as well as on the repository after committing.git config – Sets configuration values for your user name, email, file formats and more.git init – Initializes a git repository – creates the initial ‘.git’ directory in a new or in an existing project.git clone – Makes a Git repository copy from a remote source. Also adds the original location as a remote so you can fetch from it again and push to it if you have permissions.git add – Adds files changes in your working directory to your index.git rm – Removes files from your index and your working directory so they will not be tracked.git commit – Takes all of the changes written in the index, creates a new commit object pointing to it and sets the branch to point to that new commit.git status – Shows you the status of files in the index versus the working directory.git branch – Lists existing branches, including remote branches if ‘-a’ is provided. Creates a new branch if a branch name is provided.git checkout – Checks out a different branch – switches branches by updating the index, working tree, and HEAD to reflect the chosen branch.git merge – Merges one or more branches into your current branch and automatically creates a new commit if there are no conflicts.git reset – Resets your index and working directory to the state of your last commit.git tag – Tags a specific commit with a simple, human readable handle that never moves.git pull – Fetches the files from the remote repository and merges it with your local one.git push – Pushes all the modified local objects to the remote repository and advances its branches.git remote – Shows all the remote versions of your repository.git log – Shows a listing of commits on a branch including the corresponding details.git show – Shows information about a git object.git diff – Generates patch files or statistics of differences between paths or files in your git repository, or your index or your working directory.gitk – Graphical Tcl/Tk based interface to a local Git repository.

• Asp.net Session State Revisited

  - by karan@dotnet

  Every now and then I see doubts and queries which I believe is the most discussed topic in the .net environment - Asp.net Sessions. So what really are they, why are they needed and what does browser and .net do with it. These and some of the other questions I hope to answer with this post. Because of the stateless nature of the HTTP protocol there is always a need of state management in a web application. There are many other ways to store data but I feel Session state is amongst the most powerful one. The ASP.NET session state is a technology that lets you store server-side, user-specific data. Our web applications can then use data to process request from the user for which the session state was instantiated. So when does a session is first created? When we start a asp.net application a non-expiring cookie is created and its called as ASP.NET_SessionId. Basically there are two methods for this depending upon how you configure this setting in your config file. The session ID can be a part of cookie as discussed above(called as ASP.NET_SessionId) or it is embedded in the browser’s URL. For the latter part we have to set cookie-less session in our web.config file. These Session ID’s are 120-bit random number that is represented by 20-character string. The cookie will be alive until you close your browser. If you browse from one app to another within the same domain, then both the apps will use the same session ID to track the session state. Why reuse? so that you don’t have to create a new session ID for each request. One can abandon one particular Session by calling Session.Abandon() which will stop the page processing and clear out the session data. A subsequent page request causes a brand new session object to be instantiated. So what happened to my cookie? Well the session cookie is still there even when one Session.Abandon() is called and another session object is created. The Session.Abandon() lets you clear out your session state without waiting for session timeout. By default, this time-out is a 20-minute sliding expiration. This expiration is refreshed every time that the user makes a request to the Web site and presents the session ID cookie. The Abandon method sets a flag in the session state object that indicates that the session state should be abandoned. If your app does not have global.asax then your session cookie will be killed at the end of each page request. So you need to have a global.asax file and Session_Start() handler to make sure that the session cookie will remain intact once its issued after the first page hit. The runtime invokes global.asax’s Session_OnEnd() when you call Session.Abandon() or the session times out. The session manager stores session data in HttpCache with sliding expiration where this timeout can be configured in the <sessionState> of web.config file. When the timeout is up the HttpCache will remove the session state object. Sometimes we want particular pages not to time out as compared to other pages in our applications. We can handle this in two ways. First, we can set a timer or may be a JavaScript function that refreshes the page after fixed intervals of time. The only thing being the page being cached locally and then the request is not made to the server so to prevent that you can add this to your page: <%@ OutputCache Location="None" VaryByParam="None" %> Second approach is to move your page into its own folder and then add a web.config to that folder to control the timeout. Also not all pages in your application will need access to session state. For those pages that do not, you can indicate that session state is not needed and prevent session data from being fetched from the store in requests to these pages. You can disable the session state at page level like this:<%@ Page EnableSessionState="False" %>tbc…

• Transform your Oracle Tutor Documents to Your Corporate Standard

  - by mary.keane

  You have all of your company's processes documented in Oracle Tutor, and now you want to get the HTML files to reflect your company's corporate look and feel. How are you going to do this without having an HTML guru to change every HTML page? The good news is you do not need to be an HTML expert to make minor changes to your documents. All Tutor HTML files are attached to a group of style sheets, so any changes you make to the style sheets will immediately be reflected in all of your HTML documents. If you want to give it a try, here's what you do (please note that these tips are applicable to release Oracle Tutor 12.2 and greater): Navigate to your Tutor HTML directory, and copy into a draft folder a representative group of HTML files (don't forget the flowchart image files that are associated with the procedures). You'll also need to copy the following files: tutor.css tutor_notabs.css tutor_scripts.js tutor_tabs.css flow_icon.gif Here's the default look to the Oracle Tutor desk manual. Let's say I want to use my company's corporate style in the HTML documents. At Oracle, we use Oracle Red (FF0000), Oracle Black (000000), and Oracle Gray (666666). So I want to incorporate those colors into the Tutor HTML files. I open tutor.css from the draft folder in a text editor. My preference is to use Notepad, but there are others. Make sure, however, that it is a text editor, and not a word processing program. I want to change the headings to Oracle Red. The desk manual title is listed as the DMPAGETITLE, so I find that in tutor.css. The style names in the style sheets are descriptive, but sometimes you may have to experiment to find the right style (this is why you're working in a draft folder). I change the color attribute to FF00000, and then I save the document. Now I look at one of the desk manuals in my draft folder. I've successfully changed the title of the desk manual, so, now that I have more confidence that I can do this, I start changing other styles. I need to make changes in the tutor_tabs.css file as well, so I open that document. Then I look at one of the procedures. Oops! All that red is distracting, and the users may not be able to follow their procedures. So I go back to the corporate style guide, and I find some shades of gray that have been approved. So I use that, and it is now more readable. It's good enough for a first draft, and I would show it to my colleagues at this point to get their input. On my next blog, I'll discuss how to change the flowchart colors to match your corporate look and feel. Have you used the cascading styles sheets to change the look of your Tutor documents? If so, let us know what you've done in your post. Mary R. Keane Senior Development Manager, Oracle Tutor & UPK Content

• Extending Oracle CEP with Predictive Analytics

  - by vikram.shukla(at)oracle.com

  Introduction: OCEP is often used as a business rules engine to execute a set of business logic rules via CQL statements, and take decisions based on the outcome of those rules. There are times where configuring rules manually is sufficient because an application needs to deal with only a small and well-defined set of static rules. However, in many situations customers don't want to pre-define such rules for two reasons. First, they are dealing with events with lots of columns and manually crafting such rules for each column or a set of columns and combinations thereof is almost impossible. Second, they are content with probabilistic outcomes and do not care about 100% precision. The former is the case when a user is dealing with data with high dimensionality, the latter when an application can live with "false" positives as they can be discarded after further inspection, say by a Human Task component in a Business Process Management software. The primary goal of this blog post is to show how this can be achieved by combining OCEP with Oracle Data Mining® and leveraging the latter's rich set of algorithms and functionality to do predictive analytics in real time on streaming events. The secondary goal of this post is also to show how OCEP can be extended to invoke any arbitrary external computation in an RDBMS from within CEP. The extensible facility is known as the JDBC cartridge. The rest of the post describes the steps required to achieve this: We use the dataset available at http://blogs.oracle.com/datamining/2010/01/fraud_and_anomaly_detection_made_simple.html to showcase the capabilities. We use it to show how transaction anomalies or fraud can be detected. Building the model: Follow the self-explanatory steps described at the above URL to build the model.  It is very simple - it uses built-in Oracle Data Mining PL/SQL packages to cleanse, normalize and build the model out of the dataset.  You can also use graphical Oracle Data Miner®  to build the models. To summarize, it involves: Specifying which algorithms to use. In this case we use Support Vector Machines as we're trying to find anomalies in highly dimensional dataset.Build model on the data in the table for the algorithms specified. For this example, the table was populated in the scott/tiger schema with appropriate privileges. Configuring the Data Source: This is the first step in building CEP application using such an integration.  Our datasource looks as follows in the server config file.  It is advisable that you use the Visualizer to add it to the running server dynamically, rather than manually edit the file.    <data-source>         <name>DataMining</name>         <data-source-params>             <jndi-names>                 <element>DataMining</element>             </jndi-names>             <global-transactions-protocol>OnePhaseCommit</global-transactions-protocol>         </data-source-params>         <connection-pool-params>             <credential-mapping-enabled></credential-mapping-enabled>             <test-table-name>SQL SELECT 1 from DUAL</test-table-name>             <initial-capacity>1</initial-capacity>             <max-capacity>15</max-capacity>             <capacity-increment>1</capacity-increment>         </connection-pool-params>         <driver-params>             <use-xa-data-source-interface>true</use-xa-data-source-interface>             <driver-name>oracle.jdbc.OracleDriver</driver-name>             <url>jdbc:oracle:thin:@localhost:1522:orcl</url>             <properties>                 <element>                     <value>scott</value>                     <name>user</name>                 </element>                 <element>                     <value>{Salted-3DES}AzFE5dDbO2g=</value>                     <name>password</name>                 </element>                                 <element>                     <name>com.bea.core.datasource.serviceName</name>                     <value>oracle11.2g</value>                 </element>                 <element>                     <name>com.bea.core.datasource.serviceVersion</name>                     <value>11.2.0</value>                 </element>                 <element>                     <name>com.bea.core.datasource.serviceObjectClass</name>                     <value>java.sql.Driver</value>                 </element>             </properties>         </driver-params>     </data-source>   Designing the EPN: The EPN is very simple in this example. We briefly describe each of the components. The adapter ("DataMiningAdapter") reads data from a .csv file and sends it to the CQL processor downstream. The event payload here is same as that of the table in the database (refer to the attached project or do a "desc table-name" from a SQL*PLUS prompt). While this is for convenience in this example, it need not be the case. One can still omit fields in the streaming events, and need not match all columns in the table on which the model was built. Better yet, it does not even need to have the same name as columns in the table, as long as you alias them in the USING clause of the mining function. (Caveat: they still need to draw values from a similar universe or domain, otherwise it constitutes incorrect usage of the model). There are two things in the CQL processor ("DataMiningProc") that make scoring possible on streaming events. 1.      User defined cartridge function Please refer to the OCEP CQL reference manual to find more details about how to define such functions. We include the function below in its entirety for illustration. <?xml version="1.0" encoding="UTF-8"?> <jdbcctxconfig:config     xmlns:jdbcctxconfig="http://www.bea.com/ns/wlevs/config/application"     xmlns:jc="http://www.oracle.com/ns/ocep/config/jdbc">        <jc:jdbc-ctx>         <name>Oracle11gR2</name>         <data-source>DataMining</data-source>               <function name="prediction2">                                 <param name="CQLMONTH" type="char"/>                      <param name="WEEKOFMONTH" type="int"/>                      <param name="DAYOFWEEK" type="char" />                      <param name="MAKE" type="char" />                      <param name="ACCIDENTAREA"   type="char" />                      <param name="DAYOFWEEKCLAIMED"  type="char" />                      <param name="MONTHCLAIMED" type="char" />                      <param name="WEEKOFMONTHCLAIMED" type="int" />                      <param name="SEX" type="char" />                      <param name="MARITALSTATUS"   type="char" />                      <param name="AGE" type="int" />                      <param name="FAULT" type="char" />                      <param name="POLICYTYPE"   type="char" />                      <param name="VEHICLECATEGORY"  type="char" />                      <param name="VEHICLEPRICE" type="char" />                      <param name="FRAUDFOUND" type="int" />                      <param name="POLICYNUMBER" type="int" />                      <param name="REPNUMBER" type="int" />                      <param name="DEDUCTIBLE"   type="int" />                      <param name="DRIVERRATING"  type="int" />                      <param name="DAYSPOLICYACCIDENT"   type="char" />                      <param name="DAYSPOLICYCLAIM" type="char" />                      <param name="PASTNUMOFCLAIMS" type="char" />                      <param name="AGEOFVEHICLES" type="char" />                      <param name="AGEOFPOLICYHOLDER" type="char" />                      <param name="POLICEREPORTFILED" type="char" />                      <param name="WITNESSPRESNT" type="char" />                      <param name="AGENTTYPE" type="char" />                      <param name="NUMOFSUPP" type="char" />                      <param name="ADDRCHGCLAIM"   type="char" />                      <param name="NUMOFCARS" type="char" />                      <param name="CQLYEAR" type="int" />                      <param name="BASEPOLICY" type="char" />                                     <return-component-type>char</return-component-type>                                                      <sql><![CDATA[             SELECT to_char(PREDICTION_PROBABILITY(CLAIMSMODEL, '0' USING *))               AS probability             FROM (SELECT  :CQLMONTH AS MONTH,                                            :WEEKOFMONTH AS WEEKOFMONTH,                          :DAYOFWEEK AS DAYOFWEEK,                           :MAKE AS MAKE,                           :ACCIDENTAREA AS ACCIDENTAREA,                           :DAYOFWEEKCLAIMED AS DAYOFWEEKCLAIMED,                           :MONTHCLAIMED AS MONTHCLAIMED,                           :WEEKOFMONTHCLAIMED,                             :SEX AS SEX,                           :MARITALSTATUS AS MARITALSTATUS,                            :AGE AS AGE,                           :FAULT AS FAULT,                           :POLICYTYPE AS POLICYTYPE,                            :VEHICLECATEGORY AS VEHICLECATEGORY,                           :VEHICLEPRICE AS VEHICLEPRICE,                           :FRAUDFOUND AS FRAUDFOUND,                           :POLICYNUMBER AS POLICYNUMBER,                           :REPNUMBER AS REPNUMBER,                           :DEDUCTIBLE AS DEDUCTIBLE,                            :DRIVERRATING AS DRIVERRATING,                           :DAYSPOLICYACCIDENT AS DAYSPOLICYACCIDENT,                            :DAYSPOLICYCLAIM AS DAYSPOLICYCLAIM,                           :PASTNUMOFCLAIMS AS PASTNUMOFCLAIMS,                           :AGEOFVEHICLES AS AGEOFVEHICLES,                           :AGEOFPOLICYHOLDER AS AGEOFPOLICYHOLDER,                           :POLICEREPORTFILED AS POLICEREPORTFILED,                           :WITNESSPRESNT AS WITNESSPRESENT,                           :AGENTTYPE AS AGENTTYPE,                           :NUMOFSUPP AS NUMOFSUPP,                           :ADDRCHGCLAIM AS ADDRCHGCLAIM,                            :NUMOFCARS AS NUMOFCARS,                           :CQLYEAR AS YEAR,                           :BASEPOLICY AS BASEPOLICY                 FROM dual)                 ]]>         </sql>        </function>     </jc:jdbc-ctx> </jdbcctxconfig:config> 2.      Invoking the function for each event. Once this function is defined, you can invoke it from CQL as follows: <?xml version="1.0" encoding="UTF-8"?> <wlevs:config xmlns:wlevs="http://www.bea.com/ns/wlevs/config/application">   <processor>     <name>DataMiningProc</name>     <rules>        <query id="q1"><![CDATA[                     ISTREAM(SELECT S.CQLMONTH,                                   S.WEEKOFMONTH,                                   S.DAYOFWEEK, S.MAKE,                                   :                                         S.BASEPOLICY,                                    C.F AS probability                                                 FROM                                 StreamDataChannel [NOW] AS S,                                 TABLE(prediction2@Oracle11gR2(S.CQLMONTH,                                      S.WEEKOFMONTH,                                      S.DAYOFWEEK,                                       S.MAKE, ...,                                      S.BASEPOLICY) AS F of char) AS C)                       ]]></query>                 </rules>               </processor>           </wlevs:config>   Finally, the last stage in the EPN prints out the probability of the event being an anomaly. One can also define a threshold in CQL to filter out events that are normal, i.e., below a certain mark as defined by the analyst or designer. Sample Runs: Now let's see how this behaves when events are streamed through CEP. We use only two events for brevity, one normal and other one not. This is one of the "normal" looking events and the probability of it being anomalous is less than 60%. Event is: eventType=DataMiningOutEvent object=q1  time=2904821976256 S.CQLMONTH=Dec, S.WEEKOFMONTH=5, S.DAYOFWEEK=Wednesday, S.MAKE=Honda, S.ACCIDENTAREA=Urban, S.DAYOFWEEKCLAIMED=Tuesday, S.MONTHCLAIMED=Jan, S.WEEKOFMONTHCLAIMED=1, S.SEX=Female, S.MARITALSTATUS=Single, S.AGE=21, S.FAULT=Policy Holder, S.POLICYTYPE=Sport - Liability, S.VEHICLECATEGORY=Sport, S.VEHICLEPRICE=more than 69000, S.FRAUDFOUND=0, S.POLICYNUMBER=1, S.REPNUMBER=12, S.DEDUCTIBLE=300, S.DRIVERRATING=1, S.DAYSPOLICYACCIDENT=more than 30, S.DAYSPOLICYCLAIM=more than 30, S.PASTNUMOFCLAIMS=none, S.AGEOFVEHICLES=3 years, S.AGEOFPOLICYHOLDER=26 to 30, S.POLICEREPORTFILED=No, S.WITNESSPRESENT=No, S.AGENTTYPE=External, S.NUMOFSUPP=none, S.ADDRCHGCLAIM=1 year, S.NUMOFCARS=3 to 4, S.CQLYEAR=1994, S.BASEPOLICY=Liability, probability=.58931702982118561 isTotalOrderGuarantee=true\nAnamoly probability: .58931702982118561 However, the following event is scored as an anomaly with a very high probability of  89%. So there is likely to be something wrong with it. A close look reveals that the value of "deductible" field (10000) is not "normal". What exactly constitutes normal here?. If you run the query on the database to find ALL distinct values for the "deductible" field, it returns the following set: {300, 400, 500, 700} Event is: eventType=DataMiningOutEvent object=q1  time=2598483773496 S.CQLMONTH=Dec, S.WEEKOFMONTH=5, S.DAYOFWEEK=Wednesday, S.MAKE=Honda, S.ACCIDENTAREA=Urban, S.DAYOFWEEKCLAIMED=Tuesday, S.MONTHCLAIMED=Jan, S.WEEKOFMONTHCLAIMED=1, S.SEX=Female, S.MARITALSTATUS=Single, S.AGE=21, S.FAULT=Policy Holder, S.POLICYTYPE=Sport - Liability, S.VEHICLECATEGORY=Sport, S.VEHICLEPRICE=more than 69000, S.FRAUDFOUND=0, S.POLICYNUMBER=1, S.REPNUMBER=12, S.DEDUCTIBLE=10000, S.DRIVERRATING=1, S.DAYSPOLICYACCIDENT=more than 30, S.DAYSPOLICYCLAIM=more than 30, S.PASTNUMOFCLAIMS=none, S.AGEOFVEHICLES=3 years, S.AGEOFPOLICYHOLDER=26 to 30, S.POLICEREPORTFILED=No, S.WITNESSPRESENT=No, S.AGENTTYPE=External, S.NUMOFSUPP=none, S.ADDRCHGCLAIM=1 year, S.NUMOFCARS=3 to 4, S.CQLYEAR=1994, S.BASEPOLICY=Liability, probability=.89171554529576691 isTotalOrderGuarantee=true\nAnamoly probability: .89171554529576691 Conclusion: By way of this example, we show: real-time scoring of events as they flow through CEP leveraging Oracle Data Mining.how CEP applications can invoke complex arbitrary external computations (function shipping) in an RDBMS.

• Managing Scripts in Oracle SQL Developer

  - by thatjeffsmith

  You backup your databases, right? You backup you home computer – your media collection, tax documents, bank accounts, etc, right? You backup your handy-dandy SQL scripts, right? Ok, now that I’ve got your head nodding, I want to answer a question I get every so often: How can I manage my scripts in SQL Developer? This is an interesting question. First, it assumes that one SHOULD manage their scripts in their IDE. Now, what I think the question generally gets around to is, how can we: Navigate to our scripts Open them Execute them What a good IDE should have is an interface to your existing Version Control System (VCS.) SQL Developer supports out-of-the-box both Subversion and Git. You can also download an extension via check-for-updates to get support for CVS. Now, what I’m about to show you COULD be done without versioning and controlling your scripts – but I want to ask you why you wouldn’t want to do this? So, I’m going to proceed and assume that you do INDEED version your scripts already. Seeing what scripts you’ve already got in your repository This is very straightforward – just open the Team Versions panel. Then connect to your repository. Shows you the files in your source control system. Now, I could ‘preview’ said file right away. If I open the file from here, we get a temp file copy down from the server to the local machine. This is a local temp copy of the controlled script – I can read/execute, but not write to it. And that might be all you need. But, if your script calls other scripts, then you’re going to want to check out the server copy of your stuff down your local SVN working copy directory. That way when your script calls another script – you’re executing the PRODUCTION APPROVED copies of said scripts. And if you do SPOOL or other file I/O stuff, it will work as expected. To get to those said client copies of your scripts… Enter the Files Panel The Files panel is accessible from the View menu. You can get to your files, one of two ways. If you’ve touched the file recently, you can see it under the Recent tree. Otherwise, you can navigate to your local ‘checked out’ copies of your script(s). Open your local copies, see what’s changed, etc. And I can access the change history and see what’s been touched… What changes am I going to ‘push out’ if I commit this back to the server? Most of us work on teams, yes? This panel also gives me a heads up if someone else is making changes to the same file. I can see the ‘incoming’ changes as well. To Sum It Up… If I want to get a script to run: do a full get to your local directory open the script(s) The files panel will tell you if your local copy is out of date from the server and if you have made local changes you’ve forgotten to commit back up to the server and your fellow teammates. Now, if you’re the selfish type and don’t want to share, that’s fine. But you should still be backing up your scripts, and you can still use the Files panel to manage your scripts.

• SSAS: Utility to export SQL code from your cube's Data Source View (DSV)

  - by DrJohn

  When you are working on a cube, particularly in a multi-person team, it is sometimes necessary to review what changes that have been done to the SQL queries in the cube's data source view (DSV). This can be a problem as the SQL editor in the DSV is not the best interface to review code. Now of course you can cut and paste the SQL into SSMS, but you have to do each query one-by-one. What is worse your DBA is unlikely to have BIDS installed, so you will have to manually export all the SQL yourself and send him the files. To make it easy to get hold of the SQL in a Data Source View, I developed a C# utility which connects to an OLAP database and uses Analysis Services Management Objects (AMO) to obtain and export all the SQL to a series of files. The added benefit of this approach is that these SQL files can be placed under source code control which means the DBA can easily compare one version with another. The Trick When I came to implement this utility, I quickly found that the AMO API does not give direct access to anything useful about the tables in the data source view. Iterating through the DSVs and tables is easy, but getting to the SQL proved to be much harder. My Google searches returned little of value, so I took a look at the idea of using the XmlDom to open the DSV’s XML and obtaining the SQL from that. This is when the breakthrough happened. Inspecting the DSV’s XML I saw the things I was interested in were called TableType DbTableName FriendlyName QueryDefinition Searching Google for FriendlyName returned this page: Programming AMO Fundamental Objects which hinted at the fact that I could use something called ExtendedProperties to obtain these XML attributes. This simplified my code tremendously to make the implementation almost trivial. So here is my code with appropriate comments. The full solution can be downloaded from here: ExportCubeDsvSQL.zip   using System;using System.Data;using System.IO;using Microsoft.AnalysisServices; ... class code removed for clarity// connect to the OLAP server Server olapServer = new Server();olapServer.Connect(config.olapServerName);if (olapServer != null){ // connected to server ok, so obtain reference to the OLAP databaseDatabase olapDatabase = olapServer.Databases.FindByName(config.olapDatabaseName);if (olapDatabase != null){ Console.WriteLine(string.Format("Succesfully connected to '{0}' on '{1}'",   config.olapDatabaseName,   config.olapServerName));// export SQL from each data source view (usually only one, but can be many!)foreach (DataSourceView dsv in olapDatabase.DataSourceViews){ Console.WriteLine(string.Format("Exporting SQL from DSV '{0}'", dsv.Name));// for each table in the DSV, export the SQL in a fileforeach (DataTable dt in dsv.Schema.Tables){ Console.WriteLine(string.Format("Exporting SQL from table '{0}'", dt.TableName)); // get name of the table in the DSV// use the FriendlyName as the user inputs this and therefore has control of itstring queryName = dt.ExtendedProperties["FriendlyName"].ToString().Replace(" ", "_");string sqlFilePath = Path.Combine(targetDir.FullName, queryName + ".sql"); // delete the sql file if it exists... file deletion code removed for clarity// write out the SQL to a fileif (dt.ExtendedProperties["TableType"].ToString() == "View"){ File.WriteAllText(sqlFilePath, dt.ExtendedProperties["QueryDefinition"].ToString());}if (dt.ExtendedProperties["TableType"].ToString() == "Table"){ File.WriteAllText(sqlFilePath, dt.ExtendedProperties["DbTableName"].ToString()); } } } Console.WriteLine(string.Format("Successfully written out SQL scripts to '{0}'", targetDir.FullName)); } }   Of course, if you are following industry best practice, you should be basing your cube on a series of views. This will mean that this utility will be of limited practical value unless of course you are inheriting a project and want to check if someone did the implementation correctly.
