  • Efficient job progress update in web application

    - by Endru6
    Hi, Creating a web application (Django in my case, but I think the question is more general) that is administrating a cluster of workers doing queued jobs, there is a need to track each jobs progress. When I've done it using database UPDATE (PostgreSQL in this case), it severely hits the database performance, because each UPDATE creates a new row in a table, and in my case only vacuuming DB removes obsolete rows. Having 30 jobs running and reporting progress every 1 minute DB may require vacuuming (and it means huge slow downs on a front end side for all the employees working with the system) every 10 days. Because the progress information isn't critical, ie. it doesn't have to be persistent, how would you do the progress updates from jobs without using an overhead database implies? There are 30 worker servers, each doing 1 or 2 jobs simultaneously, 1 front end server which serves a web application to users, and 1 database server.

  • One application instance for two domain name

    - by dervlap
    Hello, I have two web applications in ASP.NET which are quite the same (same business logic, same DAL, same DB scheme but different instance). The only thing that I need to change is the design (logo, color,...) and the text (global and local resource) to adress two separate business sector. We cannot "subdomain" the application because we need the two app "seems to be" independant. Is it a good idea to run only one instance for the 2 web applications. For example : I will have 2 hostnames : mycompagny.com and mycompagny2.com and I will put an HTTP Module which will set a string which will be propagated in my application like 'company' and 'company2'. I will instanciate the dal only once but the connection string will change depending on the string 'company' or 'company2'. Any pros and cons ? Any other alternatives ?

  • Web Service Security java

    - by WhoAmI
    My web service was created some time back using IBM JAX-RPC. As a part of enhancement, I need to provide some security to the existing service. One way is to provide a handler, all the request and response will pass through that handler only. In the request I can implement some authentication rules for each and every application/user accessing it. Other than this, What are the possible ways for securing it? I have heard someting called wsse security for web service. Is it possible to implement it for the JAX-RPC? Or it can be implemented only for JAX-WS? Need some helpful inputs on the wsse security so that i can jump learning it. Other than handler and wsse security, any other possible way to make a service secure? Please help.

  • Creative an interactive GUI for a web application

    - by user2125844
    I have to create a web application (preferably using the Google App Engine) that will allow users to access it through a url link (not a Desktop application). The application graphically looks like a flow chart and each item in the chart can be selected to pull up a video (not in another window). It is recommended that I use Python. I have never made anything for the web before. Is there a best Python GUI API I should use? I've read quite a bit about Django so far I'm not sure if it is the best fit for this or not. Does anyone have any tips for starting this project? Thanks in advance!

  • Java Web Application

    - by Mark R
    I am interested in creating a simple web application that will take in user input, convert it to an XML file and send the file to a database. Coding wise I feel I am okay, it is just the general setup and what implementation to use I am a bit unsure of. At the moment I have a JSP page containing a form, the user fills out the form and on submit a get method is sent to a servlet, in the servlet doGet() method the servlet is instantiating a java object and passing it the user inputted data. The java object then writes that data to an XML file and sends it to the database via REST. All I would be interested to know is if this the standard/optimal way of creating such a web application. Any and all feedback is appreciated. Thanks

  • Web Self Service installation on Windows

    - by Rajesh Sharma
    Web Self Service (WSS) installation on windows is pretty straight forward but you might face some issues if deployed under tomcat. Here's a step-by-step guide to install Oracle Utilities Web Self Service on windows.   Below installation steps are done on: Oracle Utilities Framework version 2.2.0 Oracle Utilities Application - Customer Care & Billing version 2.2.0 Application server - Apache Tomcat 6.0.13 on default port 6500 Other settings include: SPLBASE = C:\spl\CCBDEMO22 SPLENVIRON = CCBV22 SPLWAS = TCAT   Follow these steps for a Web Self Service installation on windows: Download Web Self Service application from edelivery.   Copy the delivery file Release-SelfService-V2.2.0.zip from the Oracle Utilities Customer Care and Billing version 2.2.0 Web Self Service folder on the installation media to a directory on your Windows box where you would like to install the application, in our case it's a temporary folder C:\wss_temp.   Setup application environment, execute splenviron.cmd -e <ENVIRON_NAME>   Create base folder for Self Service application named SelfService under %SPLEBASE%\splapp\applications   Install Oracle Utilities Web Self Service   C:\wss_temp\Release-SelfService-V2.2.0>install.cmd -d %SPLEBASE%\splapp\applications\SelfService   Web Self Service installation menu. Populate environment values for each item.   ******************************************************** Pick your installation options: ******************************************************** 1. Destination directory name for installation.             | C:\spl\CCBDEMO22\splapp\applications\SelfService 2. Web Server Host.                                         | CCBV22 3. Web Server Port Number.                                  | 6500 4. Mail SMTP Host.                                          | CCBV22 5. Top Product Installation directory.                      | C:\spl\CCBDEMO22 6.     Web Application Server Type.                         | TCAT 7.     When OAS: SPLWeb OC4J instance name is required.     | OC4J1 8.     When WAS: SPLWeb server instance name is required.   | server1   P. Process the installation. Each item in the above list should be configured for a successful installation. Choose option to configure or (P) to process the installation:  P   Option 7 and Option 8 can be ignored for TCAT.   Above step installs SelfService.war file in the destination directory. We need to explode this war file. Change directory to the installation destination folder, and   C:\spl\CCBDEMO22\splapp\applications\SelfService>jar -xf SelfService.war   Review SelfServiceConfig.properties and CMSelfServiceConfig.properties. Change any properties value within the file specific to your installation/site. Generally default settings apply, for this exercise assumes that WEB user already exists in your application database.   For more information on property file customization, refer to Oracle Utilities Web Self Service Configuration section in Customer Care & Billing Installation Guide.   Add context entry in server.xml located under tomcat-base folder C:\spl\CCBDEMO22\product\tomcatBase\conf   ... <!-- SPL Context -->           <Context path="" docBase="C:/spl/CCBDEMO22/splapp/applications/root" debug="0" privileged="true"/>           <Context path="/appViewer" docBase="C:/spl/CCBDEMO22/splapp/applications/appViewer" debug="0" privileged="true"/>           <Context path="/help" docBase="C:/spl/CCBDEMO22/splapp/applications/help" debug="0" privileged="true"/>           <Context path="/XAIApp" docBase="C:/spl/CCBDEMO22/splapp/applications/XAIApp" debug="0" privileged="true"/>           <Context path="/SelfService" docBase="C:/spl/CCBDEMO22/splapp/applications/SelfService" debug="0" privileged="true"/> ...   Add User in tomcat-users.xml file located under tomcat-base folder C:\spl\CCBDEMO22\product\tomcatBase\conf   <user username="WEB" password="selfservice" roles="cisusers"/>   Note the password is "selfservice", this is the default password set within the SelfServiceConfig.properties file with base64 encoding.   Restart the application (spl.cmd stop | start)   12.  Although Apache Tomcat version 6.0.13 does not come with the admin pack, you can verify whether SelfService application is loaded and running, go to following URL http://server:port/manager/list, in our case it'll be http://ccbv22:6500/manager/list Following output will be displayed   OK - Listed applications for virtual host localhost /admin:running:0:C:/tomcat/apache-tomcat-6.0.13/webapps/ROOT/admin /XAIApp:running:0:C:/spl/CCBDEMO22/splapp/applications/XAIApp /host-manager:running:0:C:/tomcat/apache-tomcat-6.0.13/webapps/host-manager /SelfService:running:0:C:/spl/CCBDEMO22/splapp/applications/SelfService /appViewer:running:0:C:/spl/CCBDEMO22/splapp/applications/appViewer /manager:running:1:C:/tomcat/apache-tomcat-6.0.13/webapps/manager /help:running:0:C:/spl/CCBDEMO22/splapp/applications/help /:running:0:C:/spl/CCBDEMO22/splapp/applications/root   Also ensure that the XAIApp is running.   Run Oracle Utilities Web Self Service application http://server:port/SelfService in our case it'll be  http://ccbv22:6500/SelfService   Still doesn't work? And you get '503 HTTP response' at the time of customer registration?     This is because XAI service is still unavailable. There is initialize.waittime set for a default value of 90 seconds for the XAI Application to come up.   Remember WSS uses XAI to perform actions/validations on the CC&B database.

  • Are there any subversion "dash board" web applications that can show me a list of recent commits from all my repositories?

    - by Joe
    I am looking for something like a subversion dashboard that at the very least can show me commits from across a group of repositories. Is there anything like this available? Since it could just as well be dead simple and I can't find anything immediately I am thinking if just scratching my own itch here, but I am hoping someone has wanted this before? Are there any subversion "dashboards" that an show me even a simple twitter-like list of commits from across my repositories?

  • Internet Explorer-like clicking sound without using Explorer

    - by Tom
    When I switch on my Windows 7 laptop a few minutes after turning it on I hear a single click sound like the one Internet Explorer gives during browsing. I don't use Explorer at all. I use Firefox. What can it be then? Is it coming from Explorer running in the background? Or is it not related to Explorer at all? Has anyone else experienced something like this?

  • Take Control Of Web Control ClientID Values in ASP.NET 4.0

    Each server-side Web control in an ASP.NET Web Forms application has an <code>ID</code> property that identifies the Web control and is name by which the Web control is accessed in the code-behind class. When rendered into HTML, the Web control turns its server-side <code>ID</code> value into a client-side <code>id</code> attribute. Ideally, there would be a one-to-one correspondence between the value of the server-side <code>ID</code> property and the generated client-side <code>id</code>, but in reality things aren't so simple. By default, the rendered client-side <code>id</code> is formed by taking the Web control's <code>ID</code> property and prefixed it with the <code>ID</code>

  • Windows Live Family Safety Service keeps closing Start Menu

    - by Jim McKeeth
    Got my kids a new Toshiba Laptop for Christmas. I was setting it all up for them so it would be ready to go. Tonight I installed Windows Live Family Safety Parental Controls. In the process of testing I discovered that on all the accounts the Start Menu closes automatically within 3 seconds (or less) of opening. It seems that it happens every 3 seconds, so sometimes it is immediate, and if I open it again then it will stay open for a full 3 seconds. This of course is rather annoying, and I need to wrap it up so it is ready to go under the tree. I disabled the Windows Live Family Safety Service, and that fixed it. Enable it again and the behavior returns. Is this a feature of the service? Can I disable that feature and keep the other features?

  • Tooltips shadow stuck on desktop

    - by faulty
    I tends to get this problem from time to time. The tooltips with a shadow appearing on top of everything. It's the shadow of the tooltips not disappearing after the tooltips disappear. The last one I had the tooltips was from the wifi connection list at the systray. This problem also happen to me on another computer. Both running Win7 with ATI gpu. I found this similar post Menu command stuck on screen but none of the solution helped. In fact the "Fade or slide tooltips into view" has been unchecked from the beginning. Ending task of "dwm.exe" also doesn't help. So far the only way to resolve this by restarting window. I can't post picture yet, so can't show any screenshot. Edit: Just tested a few more trick which doesn't work. 1. Turn of aero 2. Hibernate 3. Switch main display to external display and switch back. 4. Change resolution

  • What expectation should I have of South African web development rates / duration? [closed]

    - by Warren van Rooyen
    I am a developer but only intend on doing the front-end work for getting Reddit-like upvote / downvote functionality going on an upcoming site I'm building. I have never had to contract a developer for back-end work to implement code for me so I am quite in the dark on how much I should expect to pay and how long it could take to get the site going. I could be taken for a ride as the developer could distort the time it would take at a seemingly regular rate (hourly/day) or could otherwise distort their rate. Please could you give me help on this. I know you need some guidance on the nature of the site so here it is. I have a Reddit type template with CSS and PHP included. I then downloaded Pligg code that's intended to do the job of the Reddit upvote downvote functionality. How long would a developer roughly need to unite the theme and front end with the back-end functionality? I do understand it's not a lot of info but I'm sure you're experienced enough to have an instinct for the size of the project. Also, should I work on an hourly/day rate/ project payment agreement?
