  • Setup Custom Portal & Content Enabled Domain

    - by Stefan Krantz
    When overlooking the past year we have seen a large increase in deployments where only some parts of the WebCenter Suite infrastructure has been used. The most common from my personal perspective is a domain topology that includes: WebCenter Custom Portal, WebCenter Content and Oracle HTTP ServicesToday its very common to see installation where the whole suite is installed when the use case only requires the custom portal and some sub component like WebCenter Content. This post will go into detail on how to minimize the deployment time and effort by only laying down the necessary managed servers needed, by following this proposed method you will minimize the configuration steps and only install the required components and schema's, configure only the necessary components and minimize the impact of architectural changes through reduced dependencies. Assumptions: Oracle 11g Database installed SYS or equivalent access to Database to setup schema's via RCU Running Operating System supporting JDK 7 Update 2 (Check support matrix here) Good understanding of WebLogic Architecture Binaries: Oracle JDK 7 Update 2 (1.7.0_02) (Download) Oracle WebLogic 10.3.6 (Download) Oracle WebCenter Binaries (11.1.1.6) (Download) Oracle WebCenter Content Binaries (11.1.1.6) (Download 1) (Download 2) Oracle HTTP Services (11.1.1.6) (Download) Oracle Repository Creation Utility (11.1.1.6) (Download Linux or Windows) Schema's: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal";

  • Reinstalled Ubuntu 12.04 and now I cannot change preferences like theme, wallpaper, and nautilus preferences

    - by krishnab
    So I just down-rev'd ubuntu from 13.04 back to 12.04 LTS desktop 64 (Precise). I am using Unity. I just reformatted the Ubuntu partition, but kept my home directory intact, and everything seemed to reconnect just fine. No data was lost. However, I found that I cannot seem to change my preferences. So I cannot seem to change my desktop background, no matter how many ways I try--Ubuntu Tweak, Gnome Tweak, system settings. I also cannot change the system GTK+ theme, though apparently I am able to change the windows border theme. Further, I cannot seem to change my Nautilus preferences--so I cannot seem the make the default view a list view, and I cannot make the "single-click" behavior the default. I even went into the nautilus org.gnome.nautilus settings to manually change things, but no luck. I thought it was a permissions issue, so I did a chown on the home folder and on the .gvfs folder. Still no luck. So somewhere there seems to be a permission that I am not catching. Does anyone have any suggestions? Thanks.

  • Need assistance matching a general theme style as well as eCommerce capability

    - by humble_coder
    I'm in the process of acquiring a new design client. They are getting into the business of "auto parts wholesaling" and they want a storefront. My preference is/was to create something from scratch. However, here is an established trend in their particular market (similar parts, layout, etc). They insist on following the existing visual trend, as per the following: http://www.xtremediesel.com/ http://www.thoroughbreddiesel.com/ http://www.alligatorperformance.com/ My plan of attack at this point is to find a comparable WP theme and a flexible (but useful) backend/product management. Their current demo site (which their previous developer made a stab at) is using Pinnacle Cart. It is no where near what they need, nor is it intuitive to work with. I was actually considering Magento for its greater abilities but I'm still considering options. That said, my two primary dilemmas are as follows: 1) I need a theme that mimics the general style of those listed. They explicitly said they didn't want anything too clean (e.g. ThemeForest, Woothemes) as it "wasn't rugged or busy looking enough" for their field. 2) I need a WP/Magento/WP e-Commerce (or any one of a host of other) plugin that will allow for bulk import/update of nearly 200,000 products, descriptions and images. I'm not opposed to manually interfacing with the DB for import, but in the end, I need a store/system that doesn't needlessly add 50 tables to accommodate some "wet behind the ears" concept of table normalization and is easy to add to. Anyway, if anyone has any quality suggestions regarding either of these issues, it would be most appreciated. Best.

  • How do I theme the Nautilus background image?

    - by Kesymaru
    I want to change the background image in the Nautilus file browser. My idea is to put my own style in the background. I'm using Ubuntu 11.10 and Nautilus is version 3. I know that I have to change the nautilus.css file of the theme, but the problem is that there is not a parameter for the background. I just want to apply an image but I can't find the file or parameter to change it. The CSS file is in the directory /home/UserName/.theme/MyTheme/gtk-3.0/apps. I've changed the nautilus.css file. I wrote two new lines using CSS style but I don't know where the correct place is to put it. The lines are: background-image: url("carbon.jpg"); background-repeat: repeat; Obviously I put the image called carbon.jpg in the same directory of nautilus.css, but this change doesn't work because I need to know whichs class displays the Nautilus file browsing frame. If I find this class I guess that this code will work. If someone knows how to do it, please tell me because I really want to make this change.

  • Dark or light theme for Android apps?

    - by Philip Sheard
    My app allows the user to choose between a dark and a light theme, but which should it use as the default? It is a field sales app, a kind of glorified invoicing app for enterprise users. It is much larger than most apps in Google Play, and targets a vertical market. Originally I developed the app with a dark font, which was fairly standard at the time. That is still my personal preference, but most modern apps seem to have a light font.

  • White text on yellow background in popup elements with Ambiance theme

    - by texnic
    In Eric4, when I select the "What's This" tool and then click on something to get a pop-up explanation, the resulting text appears white on yellow (unreadable). The tool-tips are fine (white on black). If I change the theme to any other, the text is black on yellow. I've found some posts on the internet about such behaviour with Skype and LibreOffice, but it doesn't seem to me to be the program-specific problem since it appears in various apps. How can I tune it?

Due to its responsive feature, Ajax technology has been incorporated in many platforms and one of the most popular ones is the WordPress Ajax theme.

  • PHP Requests Being Blocked After Making About 25 in Ten Minutes

    - by Daniel Stern
    We have an administrative portal where we run PHP functions through a Javascript portal using ajax for administrative purposes. For example, we might have a function called updateAllDatabaseEntries() which would call AJAX functions in rapid succession, with those functions each executing numerous SQL queries. The problem is after making several successive requests from the same computer (not an excessive amount, maybe 30 in ten minutes) the system will stop responding to any PHP, HTTP requests ETC ONLY from my computer. From other computers in the office the panel can still be accessed, and access is restored to this computer after about 15 minutes. We believe this is not a glitch but some kind of security feature built into our server, possibly relating to Suhosin and likely well-intentioned but currently preventing us from running our system administration.

  • Can't install "Docky" theme?

    - by Earl Larson
    So to install a theme for Docky on Ubuntu I had to extract the theme from the Archive Manager via root to /usr/local/share/docky/themes. I did this but it didn't show up in the theme choices. Then I tried just pressing the install button and locating it but I couldn't see the tar file. I then extracted the tar file to the desktop and tried selecting that to install but nothing. What am I doing wrong!?

    What are the best resources for Wordpress theme-development? I am currently in the phase of starting my own blog, and don't want to use one of the many free themes. I already have a theme for my website, so I want to read about best-practices. Any advice on how to get started would be very welcome :) I have now created my theme (wohoo!), and thought I should summarize the best resources I found. Lets see.. Resources: ThemeTation's three-part guide to create a wordpress-theme from scratch Nettuts.com's guide: How to Create a Wordpress Theme from Scratch (And Part 2) Didn't actually use this, it's a quite new article, but anyway - it's great. It will get a follow-up in the next few days too.. Wordpress.org's own guide on templates Definatly a must-read for everyone new to wordpress-designing.. "The loop" Essential knowledge, also a must-read Directory of all the template tags Used by wordpress to actually output blog-content.. Inspiration: Smashing Magazine's lists: first, one more, yet another one Wordpress.org's theme-directory

  • Windows XP failing to set theme correctly on auto-login

    - by Alois Mahdal
    On several testing machines we have, when automatic login (as Administrator) is activated, Windows fails to set theme (Display properties - Themes) correctly. Particularly, even if theme is set to "Windows Classic", visually it's obvious that "Windows XP" is applied (the one with blue title bars and red "X" butons). I have only seen this happen when Auto-login is set--we always use Administrator on XP. Even if I log out and back in manually, theme is set correctly. Apart from logging out and in, it's also possible to reset theme in "Display properties". It does not happen in 100% of the cases, but it's way over 50%. Definitely it's often enough to be annoying. I believe this is a bug in Windows XP. I have never encountered it on other Windows versions. Does anybody know how to avoid this issue once forever? (Or can anybody provide explanation, relevant links, etc.?)

  • Do Not Optimize Without Measuring

    - by Alois Kraus
    Recently I had to do some performance work which included reading a lot of code. It is fascinating with what ideas people come up to solve a problem. Especially when there is no problem. When you look at other peoples code you will not be able to tell if it is well performing or not by reading it. You need to execute it with some sort of tracing or even better under a profiler. The first rule of the performance club is not to think and then to optimize but to measure, think and then optimize. The second rule is to do this do this in a loop to prevent slipping in bad things for too long into your code base. If you skip for some reason the measure step and optimize directly it is like changing the wave function in quantum mechanics. This has no observable effect in our world since it does represent only a probability distribution of all possible values. In quantum mechanics you need to let the wave function collapse to a single value. A collapsed wave function has therefore not many but one distinct value. This is what we physicists call a measurement. If you optimize your application without measuring it you are just changing the probability distribution of your potential performance values. Which performance your application actually has is still unknown. You only know that it will be within a specific range with a certain probability. As usual there are unlikely values within your distribution like a startup time of 20 minutes which should only happen once in 100 000 years. 100 000 years are a very short time when the first customer tries your heavily distributed networking application to run over a slow WIFI network… What is the point of this? Every programmer/architect has a mental performance model in his head. A model has always a set of explicit preconditions and a lot more implicit assumptions baked into it. When the model is good it will help you to think of good designs but it can also be the source of problems. In real world systems not all assumptions of your performance model (implicit or explicit) hold true any longer. The only way to connect your performance model and the real world is to measure it. In the WIFI example the model did assume a low latency high bandwidth LAN connection. If this assumption becomes wrong the system did have a drastic change in startup time. Lets look at a example. Lets assume we want to cache some expensive UI resource like fonts objects. For this undertaking we do create a Cache class with the UI themes we want to support. Since Fonts are expensive objects we do create it on demand the first time the theme is requested. A simple example of a Theme cache might look like this: using System; using System.Collections.Generic; using System.Drawing; struct Theme { public Color Color; public Font Font; } static class ThemeCache { static Dictionary<string, Theme> _Cache = new Dictionary<string, Theme> { {"Default", new Theme { Color = Color.AliceBlue }}, {"Theme12", new Theme { Color = Color.Aqua }}, }; public static Theme Get(string theme) { Theme cached = _Cache[theme]; if (cached.Font == null) { Console.WriteLine("Creating new font"); cached.Font = new Font("Arial", 8); } return cached; } } class Program { static void Main(string[] args) { Theme item = ThemeCache.Get("Theme12"); item = ThemeCache.Get("Theme12"); } } This cache does create font objects only once since on first retrieve of the Theme object the font is added to the Theme object. When we let the application run it should print “Creating new font” only once. Right? Wrong! The vigilant readers have spotted the issue already. The creator of this cache class wanted to get maximum performance. So he decided that the Theme object should be a value type (struct) to not put too much pressure on the garbage collector. The code Theme cached = _Cache[theme]; if (cached.Font == null) { Console.WriteLine("Creating new font"); cached.Font = new Font("Arial", 8); } does work with a copy of the value stored in the dictionary. This means we do mutate a copy of the Theme object and return it to our caller. But the original Theme object in the dictionary will have always null for the Font field! The solution is to change the declaration of struct Theme to class Theme or to update the theme object in the dictionary. Our cache as it is currently is actually a non caching cache. The funny thing was that I found out with a profiler by looking at which objects where finalized. I found way too many font objects to be finalized. After a bit debugging I found the allocation source for Font objects was this cache. Since this cache was there for years it means that the cache was never needed since I found no perf issue due to the creation of font objects. the cache was never profiled if it did bring any performance gain. to make the cache beneficial it needs to be accessed much more often. That was the story of the non caching cache. Next time I will write something something about measuring.

  • How to change tooltip background color in Unity?

    - by kayahr
    In a lot of applications the tooltips are just plain ugly (White text on black background, way too much contrast) or even unreadable (black or dark blue text (Hyperlinks) on black background). I want to change the background color of the tooltips to some medium gray or even some yellow or something like that, maybe even something semi-transparent. Here is a screenshot of Eclipse which displays some source code in a tool tip with black text on black background: Switching to a different theme (Something other than Ambiance or Radiance) helps but I like Ambiance and I want to keep it. It's just this darn tooltip color which is absolutely unacceptable. I found several solutions for older Ubuntu versions but they no longer work with Unity in Ubuntu 11.10 because I can't find any function to customize the Ambiance or Radiance theme. So how do I do that in the current Ubuntu version?

  • Whatchamacallit: You know how there are breadcrumbs and sliders and whatnot

    - by Richard
    What do you call it when a web site (especially corporate/retail) has a series of rows with thumbnails, each with a little caption/description beneath explaining some benefit or feature of a product or service. Is there a name for this? I'm building a theme that incorporates this kind of design and I was hoping there is some kind of shorthand for this design feature. If you don't know what I'm talking about, check out one of the links below. http://themeforest.net/item/revolution-minimalist-business-html-template/full_screen_preview/2295335 http://themes.two2twelve.com/preview?theme=freshserve

  • High contrast theme Firefox problem

    - by user87239
    I am using the high contrast inverse theme in 12.04 as I am visually impaired. This generally works great but causes a problem in Firefox as entered text e.g into a Google search is white. As the text background is also white you cannot see what you are typing. I have read through a good thirty websites with similar issues but thus far nothing works. I have tried all the settings in Firefox like un-checking "Use System Defaults" as well as manually telling Firefox what colours to use and these setting have absolutely no effect on anything.

  • Licensing Theme Music from other games

    - by HS01
    As part of my game, I thought it would be fun to make a hidden level that pays tribute to Mario Bros (one of the earliest games I ever played). It would be themed in that way with 8-bit graphics and question mark blocks and completing the level would say "Thank you but the princess is in another castle" or such. For the sound track, I'm thinking of just overlaying the standard mario theme music by playing it on a virtual keyboard using a different instrument/timing or something. My question is, am I legally safe? I'm not using anyone else's actual music, I'm just playing the same tune in a different way myself. Do I have to get licensing for this?

  • Semi-transparent parts of theme show as full white

    - by Kilian
    I am running ubuntu 10.04 64bit on a macbook pro, using the nvidia-drivers version 260.19.29. As of a recent kernel update, all the semi-transparent parts of my theme show as full white. This means: no gradients on scrollbars and buttons, 'inverted' dividers in context menu's, full white gnome-do panel etc. Does anyone know what causes this and how I can fix it? Screenshot examples below. Scrollbars: Gnome-do: 'inverted' dividers in the context menu: (Last two links are not links due to not having sufficient points)
