  • Coldfusion autorestart

    - by Comcar
    Coldfusion is automatically restarting, a lot. It comes in waves, everything seems fine for a while then the server struggles for a few minutes, restarts a lot then settles down again. I have Fusion Reactor installed, but when CF goes down FR stops logging so it's not really helping. Looking through the archived logs just shows gaps in the logs. These are all the occourances of the phrase "Coldfusion started" today. [root@server2 logs]# grep -i "Coldfusion started" server.log | grep "11/27/12" "Information","main","11/27/12","01:49:35",,"ColdFusion started" "Information","main","11/27/12","01:50:46",,"ColdFusion started" "Information","main","11/27/12","01:52:39",,"ColdFusion started" "Information","main","11/27/12","01:54:08",,"ColdFusion started" "Information","main","11/27/12","01:55:12",,"ColdFusion started" "Information","main","11/27/12","01:56:29",,"ColdFusion started" "Information","main","11/27/12","01:57:36",,"ColdFusion started" "Information","main","11/27/12","01:58:57",,"ColdFusion started" "Information","main","11/27/12","01:59:56",,"ColdFusion started" "Information","main","11/27/12","02:01:38",,"ColdFusion started" "Information","main","11/27/12","02:03:11",,"ColdFusion started" "Information","main","11/27/12","02:04:41",,"ColdFusion started" "Information","main","11/27/12","02:07:53",,"ColdFusion started" "Information","main","11/27/12","02:10:45",,"ColdFusion started" "Information","main","11/27/12","02:11:49",,"ColdFusion started" "Information","main","11/27/12","02:13:09",,"ColdFusion started" "Information","main","11/27/12","02:14:18",,"ColdFusion started" "Information","main","11/27/12","02:15:44",,"ColdFusion started" "Information","main","11/27/12","02:17:06",,"ColdFusion started" "Information","main","11/27/12","02:34:19",,"ColdFusion started" "Information","main","11/27/12","03:01:20",,"ColdFusion started" "Information","main","11/27/12","05:25:59",,"ColdFusion started" "Information","main","11/27/12","06:30:48",,"ColdFusion started" "Information","main","11/27/12","06:36:20",,"ColdFusion started" "Information","main","11/27/12","09:34:07",,"ColdFusion started" "Information","main","11/27/12","09:35:39",,"ColdFusion started" "Information","main","11/27/12","09:36:41",,"ColdFusion started" "Information","main","11/27/12","09:39:15",,"ColdFusion started" "Information","main","11/27/12","09:40:42",,"ColdFusion started" "Information","main","11/27/12","09:42:55",,"ColdFusion started" "Information","main","11/27/12","09:44:23",,"ColdFusion started" "Information","main","11/27/12","09:46:18",,"ColdFusion started" "Information","main","11/27/12","09:47:35",,"ColdFusion started" "Information","main","11/27/12","09:48:53",,"ColdFusion started" "Information","main","11/27/12","09:50:04",,"ColdFusion started" "Information","main","11/27/12","09:51:51",,"ColdFusion started" "Information","main","11/27/12","09:53:05",,"ColdFusion started" "Information","main","11/27/12","09:54:24",,"ColdFusion started" "Information","main","11/27/12","09:55:28",,"ColdFusion started" "Information","main","11/27/12","09:56:38",,"ColdFusion started" "Information","main","11/27/12","09:58:03",,"ColdFusion started" "Information","main","11/27/12","09:59:03",,"ColdFusion started" "Information","main","11/27/12","10:04:37",,"ColdFusion started" "Information","main","11/27/12","12:04:02",,"ColdFusion started" I've been looking at the live server metrics in FR on a second screen all day, the CPU, Memory and requests all seemed fine about 12 midday, then the server rebooted. Looking at the logs for the hour between 9am and 10am (more than 15 restarts in the hour), the CPU never went over 44% usage and the Memory never exceeded 53% usage - in the recorded stats at least. There is no JDBC tracking at the moment, so I'll add that to tracking and see if it's MySQL causing a problem, but can anyone help me narrow down the problem, what would cause Cold Fusion to auto restart, and I'm assuming the auto restart is only happening because Fusion Reactor is installed. It's a Red Hat 5 LAMP stack running Coldfusion 9 and Fusion Reactor 4.5.2

  • How to update data in the user information list when using FBA

    - by Flo
    I've got to support a SharePoint web application which uses FBA with a custom membership and a custom role provider to authenticate the user against two different LDAPs. The user data are only stored in the user information lists. The SSP user profiles are not used. Now one of the users got married and therefore her surname got changed in the LDAP (the one where her information are stored). But this change doesn't get provisioned into the user information list. I wondering what option I have to provision changes of user data to the user information list. I've already tried to update the last name of the user manually, but it seems as if certain information like surname, first name are not editable in the user information list. I tried to edit them as a site administrator. So what option do I have to solve this problem? Being able to edit the information per hand would also be a solution but of course not the most preferred one.

  • from MS Biology to BS Computer Science [on hold]

    - by Air Borne
    I'm Marco from Italy and I'd like to ask you a piece of advice about my career. I hold a Ms degree in Biology, I enjoyed a lot studying it and I got very good grades but I didn't know what to do with my degree in the real life. Few months ago, I began to read a book about Python programming (Introduction to Computer Science, Zelle J.) and I've great fun learning Python as a beginner, I wake up in the morning thinking about doing excersies and writing simple programs with python :) I'm also watching free lectures from MIT open courseware, and I'm feeling a certain degree of regrets for never asking myself what was computer science, since it seems to me it's a magic world. After weeks of doubts, I made a move :) I applied for a CS bachelor degree abroad, I got an interview and I'm going to start this great adventure next September. I feel incredibly excited at it, but a little bit scared too. Scared because sometimes I think I'm making a great mistake for my life restarting from a bachelor in a completely different area of study. Sometimes I hear people saying the IT market is bad, sometimes I hear other ones saying quite the opposite instead. Moreover, some colleagues of mine suggested me to try to get into Bioinformatics, instead of CS. My question is: I want to really discover if CS is for me, I mean the passion of my life. I know I'm just a beginner and I can't say nothing about it yet. What do you suggest me: CS or Bioinformatics? If I get a Bs in CS, could I get into bioinformatics without relevant experience, taking into account I have a Ms Biology degree? Any comment is appreciated, thanks in advance.

  • New Information Center - Reviewing Security For FMW 11g

    - by Daniel Mortimer
    Announcing ... Information Center: Reviewing Security For Oracle Fusion Middleware 11g [ID 1458051.2] has been published.  Screenshot of ID 1458051.2 What is an Information Center? Information Centers use widgets to aggregate knowledge content, such as support documents, product documentation, support community threads, which is pertinent to a given task or intent. Widgets either contain static lists or better still some widgets are dynamic. A dynamic widget uses a query criteria to present a list of support documents relevant to the title / subject matter of the widget. The content of a dynamic widget is refreshed automatically every 24 hours. Once you are in an Information Center, you can use the left hand menu to navigate to other Tasks / Intent Information Centers (e.g "Install and Configure", "Patch", "Troubleshoot", "Upgrade" which are available for the chosen product. Are Information Centers easy to find? You can go straight to the new "Reviewing Security" Information Center by using the hyperlink given above. There are, however, two other methods which make Information Centers easier to find. Browse Knowledge Refine Your Search Browse Knowledge The "Browse Knowledge" is currently found in the "Knowledge" Tab Page in My Oracle Support. As illustrated by the screenshots below, you can find Information Centers by choosing a product (e.g "Oracle Fusion Middleware"), a version and an action / intent. If an Information Center exists for your selection the "Advisor Found" button is enabled. Clicking on this button will take you straight to the desired Information Center.Screenshot - Browse Knowledge 1 Screenshot - Browse Knowledge 2 Screenshot - Browse Knowledge 3 Refine Your Search Refine your search is a dialogue which is triggered by certain keywords that you may enter into the Global Search field in the top right hand corner of My Oracle Support. The "Refine Your Search" works in a similar manner to "Browse Knowledge". Choose your product and version. The appropriate Task / Intent should already be selected for you. Thereafter, click the Go button. Screenshot - Refine Your Search 1 Screenshot - Refine Your Search 2 Screenshot - Refine Your Search 3

  • The Freemium-Premium Puzzle

    The more time I spend thinking about the value of information, the more I found that digitalizing information significantly changed the 'information markets', potentially in an irreversible manner. The graph at the bottom outlines my current view. The existing business models tend to be the same in the digital and analogue information world, i.e. revenue is derived from a combination of consumers' payments and advertisement. Even monetizing 'meta-information' such as search engines isn't new. Just think of the once popular 'Who'sWho'. What really changed is the price-value ratio. The curve is pushed down, closer to the axis. You pay less for the same, or often even get more for less. If you recall the capabilities I described in relevance of information you will see that there are many additional features available for digital content compared to analogue content. I think this is a good 'blue ocean strategy' by combining existing capabilities in a new way. (Kim W.C. & Mauborgne, R. (2005) Blue Ocean Strategies. Boston: Harvard Business School Publishing.). In addition the different channels of digital information distribution significantly change the value of information. I will touch on this in one of my next blogs. Right now, many information providers started to offer 'freemium' content through digital channels, hoping to get a premium for the 'full' content. No freemium seems to take them out of business, because they are apparently no longer visible in today's most relevant channels of information consumption. But, the more freemium is provided, the lower the premium gets; a truly puzzling situation. To make it worse, channel providers increasingly regard information as a value adding and differentiating activity. Maybe new types of exclusive, strategic alliances will solve the puzzle, introducing new types of 'gate-keepers', which - to me - somehow does not match the spirit of the WWW and the generation Y's perception of information consumption and exchange.

  • Opensource package for securly allowing users to log in and provide information

    - by JTS
    I have a site written in mostly php and html. I also have a sql database of personal information like names and addresses. I would like my users to be able to log in to my website with a login I can email or snail mail to them, and view and edit their information on my database. Users can currently enter information online I and store it in my database but they can't view or edit stored information. I can add the code to do this, but when I give users the ability to view information I suddenly have a lot more security concerns. Is there an open source package to deal with allowing users to do something like this? Or is there an established convention for this? I know this is a pretty basic question, and there might be some good literature about it that I have yet to find, so if someone can just point me in the direction of some of that information, or better yet give me firsthand some information about this that would be great.

  • Why are invariants important in Computer Science

    - by Antony Thomas
    I understand 'invariant' in its literal sense. I also recognize them when I type code. But I don't think I understand the importance of this term in the context of computer science. Whenever I read conversations\white papers about language design from famous programmers\computer scientists, the term 'invariant' keeps popping up as a jargon; and that is the part I don't understand. What is so special about it?

  • How to encrypt information in aspx page?

    - by Jimmyc
    Hi all, I know it's a silly question but , My client asked for encrypting some information form their payment system to prevent user stealing personal information. The system is web-base and written by ASP.NET We have tried some annoying solution such as JavaScript no right-click or css-no-print but apparently my client didn't like it. so are there any commercial solution to encrypt information in aspx produced html pages? or someone can tell me how to pursuit my client to stop these "prevent stealing" idea in a web-base system?

  • Is There A Central Repository of Javascript Information?

    - by Brian
    For example, if you want information of PHP functions, you can go to http://www.php.net/ . If you want information of Perl functions you can to to http://www.cpan.org/ and/or use perldoc. If you want information on Java you can go to http://java.sun.com and/or use javadoc. However, if you want information on Javascript methods/functions and their attributes, return values, etc. where do you go? The reason I ask is I was playing with the "focus()" method and wondering if it could be passed any values or if it returned anything when called. I have done a cursory Google search but haven't found much. Does such a beast exist or am I out of luck? Thanks for reading, and have a good day.

  • Consumer Oriented Search In Oracle Endeca Information Discovery – Part 1

    - by Bob Zurek
    Information Discovery, a core capability of Oracle Endeca Information Discovery, enables business users to rapidly search, discover and navigate through a wide variety of big data including structured, unstructured and semi-structured data. One of the key capabilities, among many, that differentiate our solution from others in the Information Discovery market is our deep support for search across this growing amount of varied big data. Our method and approach is very different than classic simple keyword search that is found in may information discovery solutions. In this first part of a series on the topic of search, I will walk you through many of the key capabilities that go beyond the simple search box that you might experience in products where search was clearly an afterthought or attempt to catch up to our core capabilities in this area. Lets explore. The core data management solution of Oracle Endeca Information Discovery is the Endeca Server, a hybrid search-analytical database that his highly scalable and column-oriented in nature. We will talk in more technical detail about the capabilities of the Endeca Server in future blog posts as this post is intended to give you a feel for the deep search capabilities that are an integral part of the Endeca Server. The Endeca Server provides best-of-breed search features aw well as a new class of features that are the first to be designed around the requirement to bridge structured, semi-structured and unstructured big data. Some of the key features of search include type a heads, automatic alphanumeric spell corrections, positional search, Booleans, wildcarding, natural language, and category search and query classification dialogs. This is just a subset of the advanced search capabilities found in Oracle Endeca Information Discovery. Search is an important feature that makes it possible for business users to explore on the diverse data sets the Endeca Server can hold at any one time. The search capabilities in the Endeca server differ from other Information Discovery products with simple “search boxes” in the following ways: The Endeca Server Supports Exploratory Search.  Enterprise data frequently requires the user to explore content through an ad hoc dialog, with guidance that helps them succeed. This has implications for how to design search features. Traditional search doesn’t assume a dialog, and so it uses relevance ranking to get its best guess to the top of the results list. It calculates many relevance factors for each query, like word frequency, distance, and meaning, and then reduces those many factors to a single score based on a proprietary “black box” formula. But how can a business users, searching, act on the information that the document is say only 38.1% relevant? In contrast, exploratory search gives users the opportunity to clarify what is relevant to them through refinements and summaries. This approach has received consumer endorsement through popular ecommerce sites where guided navigation across a broad range of products has helped consumers better discover choices that meet their, sometimes undetermined requirements. This same model exists in Oracle Endeca Information Discovery. In fact, the Endeca Server powers many of the most popular e-commerce sites in the world. The Endeca Server Supports Cascading Relevance. Traditional approaches of search reduce many relevance weights to a single score. This means that if a result with a good title match gets a similar score to one with an exact phrase match, they’ll appear next to each other in a list. But a user can’t deduce from their score why each got it’s ranking, even though that information could be valuable. Oracle Endeca Information Discovery takes a different approach. The Endeca Server stratifies results by a primary relevance strategy, and then breaks ties within a strata by ordering them with a secondary strategy, and so on. Application managers get the explicit means to compose these strategies based on their knowledge of their own domain. This approach gives both business users and managers a deterministic way to set and understand relevance. Now that you have an understanding of two of the core search capabilities in Oracle Endeca Information Discovery, our next blog post on this topic will discuss more advanced features including set search, second-order relevance as well as an understanding of faceted search mechanisms that include queries and filters.

  • How to teach computer science ?

    - by proferikson
    I am just starting to teach computer science. It's just the basic level. I'm finding that I sometimes don't know how to approach topics in a way that lets students easily understand. I've found that the best thing is to use analogies. A terrible one, that worked well, was presenting recursion by using the process of eating a burger. (You eat one bite, then you eat the rest). Interesting real world examples do wonders here. I'd like to know the techniques you have used for teaching, or teachers you've had have used that proved particularly effective. I'd also like to know your best analogies and examples for topics in CS101, especially for those harder to grasp topics. I'm teaching the class in Java (as required).

  • Which numeral systems are useful in computer science?

    - by authchir
    I am wondering which numeral system different programmers are using, or would use if their language has support for them. As an example, in C++ we can use: Octal by prefixing with 0 (e.g. 0377) Decimal by default (e.g. 255) Hexadecimal by prefixing with 0x (e.g. 0xff) When working with bitmask, I am using hexadecimal but would sometimes want to be able to express binary numbers directly. I know some programming language support it with 0b syntax (e.g. 0b11111111). Is there any other numeric system useful in some computer science domain (e.g. cryptography, codecs, 3D graphics, etc)?

  • Reporter seeking comments on computer science education [closed]

    - by user63982
    I'm a reporter doing a story for a tech website on computer science education, the need for software engineers, and the proficiency of new engineer hires. I would love to chat or exchange emails with anyone on this site who has an opinion on cs education and whether it did or did not prepare them for a job, and the pluses and minuses of the theoretical vs. the practical. I saw 1051's post and its comments and would love to connect with the poster and any of the commenters. Or anyone else with an opinion. I look forward to hearing from you. Thank you.
