  • Is any tool can help create/fix a table into normal form?

    - by WuYi
    Hi,I know the importance of being normal in database design. But many people always lives with broken windows. Is any tool can help create/fix a table to normal form? I mean to force developer create table in normal form, or help to check if the table being normal base on existed data within the table. Thanks……

  • Stand-alone app to enter records through forms?

    - by OverTheRainbow
    Hello I need to find a stand-alone (ie. no OpenOffice-based tools, for instance) Windows application that can present users with forms to enter records into an SQLite database. The goal is to migrate data from Excel sheets into a serverless, single-user database like SQLite. As a bonus, the application would also have a somewhat-protected admin section so that I can also use it to CRUD data with the same app, but it's not a requirement. There are a lot of applications listed on the official SQLite site: Can someone recommend one that is meant for end-users, either open- or closed-source? Thank you.

  • Unable to set password in IIS 8 for Domain User as ApplicationPool Identity

    - by Niels R.
    I'm trying to set a Domain User account as ApplicationPool Identity in IIS 8 (Windows 2012). When trying this using the IIS Management Console I always get an error: Value does not fall within the expected range. When trying to set the identity using appcmd.exe it fails on both the command setting the username and password or the command only setting the password. Setting the username is no problem. Trying to set both the username and password [FAIL]: >appcmd set config /section:applicationPools /[name='AppPoolName'].processModel.identityType:SpecificUser /[name='AppPoolName'].processModel.userName:DOMAIN\Username /[name='AppPoolName'].processModel.password:P4ssW0rd Applied configuration changes to section "system.applicationHost/applicationPools" for "MACHINE/WEBROOT/APPHOST" at configuration commit path "MACHINE/WEBROOT/APPHOST" ERROR ( hresult:80070057, message:Failed to commit configuration changes.

  • JSF Portlets in Liferay on JBoss

    - by JBirch
    I'm currently looking at working with and deploying JSF portlets into Liferay 6.0.5, sitting on JBoss 5.1.0. I ran into a lot of trouble trying to port some JSF-y/Seam-y/EJB-y stuff I had lying around, so I thought I'd start simple and work my way up. I could generate generic portlets using the NetBeans Maven archetype for Liferay portlets absolutely fine, but it's rather irrelevant because I wanted JSF portlets I took an example JSF portlet from http://www.liferay.com/downloads/liferay-portal/community-plugins/-/software_catalog/products/5546866 and attempted to deploy into a clean, vanilla installation of Liferay 6.0.5/JBoss 5.1.0 to no avail. The log messages are reproduced at the end of this. This particular example was actually tested for GlassFish and Tomcat, so it's not particularly helpful considering I'm deplying into JBoss. I tried ripping it apart and removing the jsf implementation contained within as there is a jsf implementation shipped with JBoss (Mojarra 1.2_12, in this case). 03:16:17,173 INFO [PortletAutoDeployListener] Copying portlets for /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/deploy/richfaces-sun-jsf1.2-facelets-portlet-1.2.war Expanding: /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/deploy/richfaces-sun-jsf1.2-facelets-portlet-1.2.war into /tmp/20110201031617188 Copying 1 file to /tmp/20110201031617188/WEB-INF Copying 1 file to /tmp/20110201031617188/WEB-INF/classes Copying 1 file to /tmp/20110201031617188/WEB-INF/classes Copying 47 files to /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/jboss-5.1.0/server/default/deploy/richfaces-sun-jsf1.2-facelets-portlet.war Copying 1 file to /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/jboss-5.1.0/server/default/deploy/richfaces-sun-jsf1.2-facelets-portlet.war Deleting directory /tmp/20110201031617188 03:16:20,075 INFO [PortletAutoDeployListener] Portlets for /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/deploy/richfaces-sun-jsf1.2-facelets-portlet-1.2.war copied successfully.

  • After forced quit, “killall Finder” says “No matching processes…” but PID still exists?

    - by Old McStopher
    Here's one for ya. Upon a forced quit of the Finder with unsuccessful relaunch, "killall Finder" in terminal returns: "No matching processes belonging to you were found" Oddly enough, the PID for finder does actually show up after a "ps -A" to reveal all processes. But the time is perpetually listed as 0:00:00, upon repeated PID listings. I tried the following to manually launch it: open /System/Library/CoreServices/Finder.app But it puked: LSOpenFromURLSpec() failed with error -600 for the file /System/Library/CoreServices/Finder.app. Any other ideas on a Finder relaunch that don't involve rebooting? (I usually have 6 spaces open at once, each with a handful of apps and it's a pain reloading them all.)

  • Launch a program when another program opens

    - by metasequoia
    I would like a method for starting a program when another program starts. Specifically, I’d like a to open a MS Word document and have my citation manager open simultaneously (EndNote supports this function within MS Word preferences, but I recently switched citation managers). The batch scripts I’ve seen so far, including this one, don’t fit the bill. I’d like to be able to open any existing Word document on my drive and trigger the second program.

  • Setting up AJP with JBoss 7

    - by purlogic
    I have two different versions of JBoss on a server, JBoss 6.0 Final and JBoss 7.0.2. I can one run or the other by switching a couple of sym links and issuing a "service jboss start" command. I am, by no means, an expert in JBoss, however JBoss 6.0 appears to have AJP running out of the box with no initial configuration required on port 8009. With JBoss 7, however, I had to vi the file "standalone/configuration/standalone.xml" and add a few entries. Those entries are: In the <subsystem /> tag, I added: <connector name="ajp" protocol="AJP/1.3" socket-binding="ajp" /> In the <socket-binding-group /> tag I added: <socket-binding name="ajp" port="8009"/> Then in Apache's configuration file (httpd.conf), I added: <Proxy *> AddDefaultCharset Off Order deny,allow Allow from all </Proxy> ProxyPass /app ajp://localhost:8009/app ProxyPassReverse /app ajp://localhost:8009/app AJP proxying works with 6, not with 7... I assume it's because I haven't properly set up AJP in JBoss 7 and not entirely sure how to do that. I have searched documentation on their site with not a lot of specifics on how to do so. Any help or insight into setting up AJP with JBoss 7 would be much appreciated!!

  • 401 - Unauthorized: Access is denied error from web app running in IIS 7.5 using App Pool Identity

    - by Eric Gatesman
    I have an ASP.NET app on a Windows 2008 server, IIS 7.5. When I try to access web site, I get a login popup. If I click "cancel" I get a 401 - Unauthorized: Access is denied due to invalid credentials. The app is using Windows authentication (anonymous is disabled). The app has it's own app pool, running under the App Pool Identity. If I change the app pool to run under the NetworkService account, my website functions just fine. I'm guessing that this is just a permissions issue, but can't figure out what permissions I need to change. I gave the App Pool Identity permissions on the physical directory of the app, but that didn't solve the problem.

  • Sending email from various domains

    - by IMHO
    We are building hosted software service that is used by multiple customers. These customers want to communicate with their customers (end customer). So, today we send it from our domain: example.com However, we would like to send email to come from their specific domains. When we put their customer emails in Reply-To - it shows up as "on behalf" in clients like outlook. What are the ways to send email from their domain without installing software on their network?

  • What happens when a server has too many requests?

    - by eSKay
    I am wondering why websites crash at all. If a server has too many requests, it might queue up the request in its waiting lists and serve it when all the earlier requests have been served. That means that the request for the website will be taken care of, although it may take some more time than expected. Then, how do websites crash due to server overload?

  • Using VLANs that are routed together?

    - by dannymcc
    I have a quick question that's bugging me the more I read about VLANs. So far I understand that they are useful for dividing the network into sub-sections, but if you route them together does that not remove any security benefit? As an example, if I created a VLAN on my home network which was simply one computer, one server and one router.if I wanted to divide the network between computers and servers I could put the computer on VLAN 10 and the server on VLAN 20. Then the computer would no longer be able to communicate with the server - unless I added a static route to the router that connected the two together, basically telling VLAN 10 that VLAN 20 exists and how to communicate with it. The VLANs would then be connected in a similar way to a 'flat' network that has no VLANs. Therefore, surely, all security benefits are lost. Am I missing something?

  • Creating an app pool a month to limit the scope of issues

    - by user39550
    I have about 360 sites running on a single app pool. Now I know we have a coding issue with one of those sites, were we have accidentally coded a memory leak. So what happens is the site runs, the memory leak starts and soon the app pool runs out of memory. Then slowly but surely, the rest of the 360 sites start going down like a domino affect. I understand that the root of the problem is some bad coding, which we'll fix, but instead of bringing down said 360 sites, I was thinking, we could create a new app-pool monthly that every site we create would go into that months app pool. First, that limit the scope of the issues to 5 - 20 sites and second if one site started having issues we wouldn't be bringing down all 360 sites. Is there any issues to this thinking, possible ramifications? Thanks in Advance! Jeremiah

  • 500 Internal Server Error with PHP application

    - by James
    I have written a PHP application using Windows and XAMPP. I've been trying to run it on Ubuntu 10.10 with Lighttpd 1.4.26. Parts of the application work fine, but whenever I try to log in, I get a 500 - Internal Server Error page. The only thing that shows up in /var/log/lighttpd/error.log is 2011-02-25 13:43:13: (mod_fastcgi.c.2582) unexpected end-of-file (perhaps the fastcgi process died): pid: 1169 socket: unix:/tmp/php.socket-0 2011-02-25 13:43:13: (mod_fastcgi.c.3367) response not received, request sent: 1596 on socket: unix:/tmp/php.socket-0 for /~denton/customer-facing-portal/index.php?, closing connection If I had any output whatsoever from PHP, this would be a lot easier to debug. Any ideas on how to get some?

  • How does too many requests make a server crash?

    - by eSKay
    I am wondering why websites crash at all. If a server has too many requests, it might queue up the request in its waiting lists and serve it when all the earlier requests have been served. That means that the request for the website will be taken care of, although it may take some more time than expected. Then, how do websites crash due to server overload?

  • Good place to start learning Adobe Illustrator CS5

    - by Kush
    The question may be off topic for SU, but I couldn't find any better place than this. I've been into designing for a while now, and have learned Photoshop by myself, and currently having fairly good grip in Photoshop CS5. Now due to rising needs, I need to learn Illustrator. I'm aware with the basics of Vector graphics, but haven't worked in designing such. So, suggest me a good place where I can learn Illustrator CS5, from ground up. I headed to Youtube for first start, but I still need an appropriate place where I get to learn it from better tutor. Thanks.
