  • Oracle at ASMC PDI 2012

    - by jeffrey.waterman
    Recently, I had the pleasure of representing Oracle at the American Society of Military Comptrollers National Professional Development Institute (PDI).  The PDI is the premier training event for resource managers in the Department of Defense and US Coast Guard.  Each year they assemble top presenters and key note speakers to convey their experiences and share the upcoming goals and vision for the Defense Department's financial and resource management community.  This year, the common themes were centered around 'auditability' and 'efficiency'.   What is auditability?  There were many definitions/themes tossed around, but to summarize my notes, it boiled down to:- the proper tracking of funds- audit readiness- proper controls- proper documentation There were sessions regarding entire programs focused on the need for auditability.  For example, FIAR: Financial Improvement and Audit Readiness (http://comptroller.defense.gov/fiar/index.html)   The FIAR stresses the "...improve(ment of) the Department's financial processes, controls and information." The entire conference, one set of solutions kept popping into my head around, "how can Oracle's solutions assist the Department of Defense", or any other Federal Agency, improve their financial processes and controls?   One answer came to mind:  Oracle Governance, Risk, and Compliance Management. Commonly referred to as "GRC". Let me summarize the main components around Oracle's GRC solution: GRC Manager: This solution is the central repository for documenting business processes, policies, and established controls.  All identified risks and issues are documented within the repository as well as action plans necessary for mitigation. GRC Controls:  This solution consists of a set of tools which are embedded with your ERP (financial, human resource, supply chain, etc.) applications to detect, prevent, and/or enforce the policies and procedures established by your Agency.  Components of the solution include:- Application Access Control Governor: a robust tool for managing application roles and responsibilities; simplify segregation of duty maintenance- Configuration Controls Governor: complete audit trail for changes made to configurations- Transactions Control Governor: track violations of internal controls; alert management to suspicious activities; be warned when high dollar transactions are occurring on an irregular basis; - Preventative Controls Governor: prevent sensitive information from being viewed by unauthorized parties; enforce field, block, and form change control If you are in the financial or resource management community and are concerned about auditability within your organization I suggest you follow up this post by reading about Oracle's GRC solutions.  www.oracle.com/grc Please feel free to follow up with thought and questions in the comments section below.  Also, if you have a topic you would like addressed in this blog, just drop me a note at [email protected]  or leave the suggestion in the comment section as well. Thank you for reading.

  • Columnstore Case Study #2: Columnstore faster than SSAS Cube at DevCon Security

    - by aspiringgeek
    Preamble This is the second in a series of posts documenting big wins encountered using columnstore indexes in SQL Server 2012 & 2014.  Many of these can be found in my big deck along with details such as internals, best practices, caveats, etc.  The purpose of sharing the case studies in this context is to provide an easy-to-consume quick-reference alternative. See also Columnstore Case Study #1: MSIT SONAR Aggregations Why Columnstore? As stated previously, If we’re looking for a subset of columns from one or a few rows, given the right indexes, SQL Server can do a superlative job of providing an answer. If we’re asking a question which by design needs to hit lots of rows—DW, reporting, aggregations, grouping, scans, etc., SQL Server has never had a good mechanism—until columnstore. Columnstore indexes were introduced in SQL Server 2012. However, they're still largely unknown. Some adoption blockers existed; yet columnstore was nonetheless a game changer for many apps.  In SQL Server 2014, potential blockers have been largely removed & they're going to profoundly change the way we interact with our data.  The purpose of this series is to share the performance benefits of columnstore & documenting columnstore is a compelling reason to upgrade to SQL Server 2014. The Customer DevCon Security provides home & business security services & has been in business for 135 years. I met DevCon personnel while speaking to the Utah County SQL User Group on 20 February 2012. (Thanks to TJ Belt (b|@tjaybelt) & Ben Miller (b|@DBADuck) for the invitation which serendipitously coincided with the height of ski season.) The App: DevCon Security Reporting: Optimized & Ad Hoc Queries DevCon users interrogate a SQL Server 2012 Analysis Services cube via SSRS. In addition, the SQL Server 2012 relational back end is the target of ad hoc queries; this DW back end is refreshed nightly during a brief maintenance window via conventional table partition switching. SSRS, SSAS, & MDX Conventional relational structures were unable to provide adequate performance for user interaction for the SSRS reports. An SSAS solution was implemented requiring personnel to ramp up technically, including learning enough MDX to satisfy requirements. Ad Hoc Queries Even though the fact table is relatively small—only 22 million rows & 33GB—the table was a typical DW table in terms of its width: 137 columns, any of which could be the target of ad hoc interrogation. As is common in DW reporting scenarios such as this, it is often nearly to optimize for such queries using conventional indexing. DevCon DBAs & developers attended PASS 2012 & were introduced to the marvels of columnstore in a session presented by Klaus Aschenbrenner (b|@Aschenbrenner) The Details Classic vs. columnstore before-&-after metrics are impressive. Scenario Conventional Structures Columnstore ? SSRS via SSAS 10 - 12 seconds 1 second >10x Ad Hoc 5-7 minutes (300 - 420 seconds) 1 - 2 seconds >100x Here are two charts characterizing this data graphically.  The first is a linear representation of Report Duration (in seconds) for Conventional Structures vs. Columnstore Indexes.  As is so often the case when we chart such significant deltas, the linear scale doesn’t expose some the dramatically improved values corresponding to the columnstore metrics.  Just to make it fair here’s the same data represented logarithmically; yet even here the values corresponding to 1 –2 seconds aren’t visible.  The Wins Performance: Even prior to columnstore implementation, at 10 - 12 seconds canned report performance against the SSAS cube was tolerable. Yet the 1 second performance afterward is clearly better. As significant as that is, imagine the user experience re: ad hoc interrogation. The difference between several minutes vs. one or two seconds is a game changer, literally changing the way users interact with their data—no mental context switching, no wondering when the results will appear, no preoccupation with the spinning mind-numbing hurry-up-&-wait indicators.  As we’ve commonly found elsewhere, columnstore indexes here provided performance improvements of one, two, or more orders of magnitude. Simplified Infrastructure: Because in this case a nonclustered columnstore index on a conventional DW table was faster than an Analysis Services cube, the entire SSAS infrastructure was rendered superfluous & was retired. PASS Rocks: Once again, the value of attending PASS is proven out. The trip to Charlotte combined with eager & enquiring minds let directly to this success story. Find out more about the next PASS Summit here, hosted this year in Seattle on November 4 - 7, 2014. DevCon BI Team Lead Nathan Allan provided this unsolicited feedback: “What we found was pretty awesome. It has been a game changer for us in terms of the flexibility we can offer people that would like to get to the data in different ways.” Summary For DW, reports, & other BI workloads, columnstore often provides significant performance enhancements relative to conventional indexing.  I have documented here, the second in a series of reports on columnstore implementations, results from DevCon Security, a live customer production app for which performance increased by factors of from 10x to 100x for all report queries, including canned queries as well as reducing time for results for ad hoc queries from 5 - 7 minutes to 1 - 2 seconds. As a result of columnstore performance, the customer retired their SSAS infrastructure. I invite you to consider leveraging columnstore in your own environment. Let me know if you have any questions.

  • I need to sell an almost-complete MMORPG project. How can I do that?

    - by Tomasz
    I need your help. We have to sell MMORPG at an advanced stage. The game has a unique engine, written on the need for the game, graphics, sound, map editor, web site etc. As it happens in the play mmorpg we can develop the characters, monsters. We can fight with other characters or to establish cooperation in solving the challenges. We can fight using own monsters, or throwing their own cards with spells. Unfortunately we have no idea how to promote the game. Ended fund and I think the whole team surrendered. How can I find a buyer? Where can I find him? Thank you for your help.

  • ISO checksum menu in nautilus

    - by dellphi
    I'm using Ubuntu 11.10 x64, Unity, and Nautilus 3.2.1 I want to be able to perform checksum ISO in Nautilus. I have searched and found: http://www.addictivetips.com/ubuntu-linux-tips/nautilus-actions-extra-add-more-features-to-ubuntu-context-menu/ and perform the procedures written in it. Once completed, the other menus appear, except the menu for "checksum verification". Then, when I run gksu nautilus-actions-config-tool I just asked to enter a user password, and .... nothing happens. What should I do, to bring up the "checksum verification" menu? I am very grateful for any response or advice given.

  • Unable to change the launcher icon size

    - by takeshin
    After upgrading to 11.10 I can't change the launcher icon size to smaller. I've tried to change it using ccsm, like described in How can I configure Unity, but the changes take no effects (restarted, tried sudo - still big icons). In the previous version of Ubuntu this solution worked. How can I change the icon size? (BTW, how can I know which Unity (2D vd 3D) I'm running and switch between?). Edit: Looks like I'm using Unity 2D and have some problems with graphics: me@my-laptop ~ $ /usr/lib/nux/unity_support_test -p Xlib: extension "GLX" missing on display ":0.0".

  • cannot rename files when saving

    - by Botond Vajna
    I am using xubuntu 13.10. Since the last update, when I am saving files I cannot rename other files, there are missing buttons in context menu like rename, cut, copy, etc... let`s say I edited the file named style.css in firefox, and I want to save it, but i do not want to overwrite the original, I want to rename the original for ex: style_orig.css and save the edited file with the name style.css. for doing that I must open thunar, navigate to that file, and rename it, after that, I can save the file from firefox. let`s reformulate this question: if I want to overwrite a file, but preserve the original, then I must make a copy of the original. Well, I can not do this when saving the file from the application, I must open thunar and navigate to that file which is an additional task I have to do. It`s a waste of time.

  • synchronization web service methodologies or papers

    - by Grady Player
    I am building a web service (PHP+JSON) to sync with my iphone app. The main goals are: Backup Provide a web view for printing / sorting, manipulating. allow a group sync up and down. I am aware of the logic problems with all of these items, Ie. if one person deletes something, do you persist this change to other users, collisions, etc. I am looking for just any book or scholarly work, or even words of wisdom to address common issues. when to detect changes of data with hashes, vs modified dates, or combination. how do address consolidation of sequential ID's originating on different client nodes (can be sidestepped in my context, but it would be interesting.) dealing with collisions (is there a universally safe way to do so?). general best practices. how to structure the actual data transaction (ask for whole list then detect changes...)

  • User connection management in Reporting Services configuration

    - by Testas
    IT professionals will use Reporting Services Configuration Manager to perform post installation tasks for SQL Server Reporting Services. Introduced in SQL Server 2005, Reporting Services Configuration Manager provides an intuitive interface to perform tasks including specifying the report server database, report manager url, and indeed one of the first post installation tasks that should be performed is backing up the encryption keys that are used to protect the sensitive information within the rdl files.  Many of the options that are selected within Reporting Services Configuration Manager are written to a number of configuration files including the rsreportserver.config file located in C:\Program Files\Microsoft SQL Server\Report Server InstanceName\Reporting Services\ReportServer folder.When opening this file you will notice that there are more configuration settings within the rsreportserver.config file than is available through the Reporting Services Configuration Manager Interface. As a result there are additional configuration options that can be defined within this file.  A customer was having a problem performing stress tests against a new Report Server that would be going live for an enterprise reporting system. One aspect of the stress test was to fire 50 connections from a single user account. When performing the stress test an error described that the maximum active request had been exceeded. Within the rsreportserver.config, there is a key that is added to the file:  <Add Key=”MaxActiveReqForOneUser” Value=”20”/>  Changing the value from 20 to 50 accommodated the needs of the stress test, however, a wider question should be asked pertaining to this setting when implementing Reporting Services to a production environment. Within an intranet environment, the default setting is appropriate when network bandwidth is high, users are known and demand for reports is particularly high from a group of users.  However, when deploying a Reporting Server solution to an extranet, or the internet, you may want to consider reducing this setting to reduce to scope of connections that can be acquired by a single user and placing unnecessary pressure on the report server. I do hope that Reporting Services Configuration Manager evolves to include an advanced page that includes an intuitive interface to change configuration settings such as the MaxActiveReqForOneUser, and also configure rendering and data extensions and define secure connection levels to the report server. All these options can be configured within the rsreportserver.config file, and these are setting that customers would like to see in Reporting Services Configuration Manager in the future.   If you think that the SQL community would benefit from this addition, you can vote on it at Microsoft Connect  https://connect.microsoft.com/SQLServer/feedback/details/565575/extending-reporting-services-configuration-manager-rscm

  • Flash doesn't work

    - by user210195
    I am a Linux and Ubuntu fan for many years, but I can not normally use it because flash does not work in any Internet browser. I already installed Ubuntu, as well as Zorin-os, on many computers, but flash won't work on any of them. Is this only my problem. Does anybody else has this problem? I've read a lot of forums, I got many responses, but none of the answers did not help me. Flash persistently doesn't work. Is there any universal solution to resolve the problem efficiently? From the beginning of the installation flash does not work and none of the solutions do not help ... I must admit that I'm pretty desperate ... I am impatiently awaiting for an answer that will solve the issue.

  • ltsp: install in chroot with GUI-Installer (lirc)

    - by Roberto
    I am trying to install "lirc" into chroot. Installing lirc requires "answering 2 questions". I am on Ubuntu Desktop 12.04. (in Virtualbox) I try this way: https://help.ubuntu.com/community/UbuntuLTSP/GuiInstallLocalApp but I had errors and then the server would hang on reboot. No big surprise, the guide says it is valid for 9.04. Maybe I could create " debconf.seeds" ( https://help.ubuntu.com/community/UbuntuLTSP/FatClients ) but I dont know how to. Could somebody point me in the right direction? thanks Roberto

  • Making a game "resize-safe"

    - by CPP_Person
    It's one thing to get the graphics aligned perfectly, it's another to do this for every single resolution and not take too much time and/or make the code unreadable due to size. Games like Battlefield 3 and Minecraft seem to manage this. But what do they do to keep things from stretching or going off the screen? I don't know any algorithms to do this. I'd like some help on this topic. I've always programmed games that only handle a single resolution, so help would be appreciate.

  • How do I get my mac to boot from an Ubuntu USB key?

    - by Vinay Gupta
    so if you select "mac" and "usb" on this download page, it gives a series of command line instructions to make a USB key which the MacBook will boot into Ubuntu from. http://www.ubuntu.com/desktop/get-ubuntu/download I've followed them to the letter two or three times on different USB keys, and it doesn't work. There's a very great deal of technical discussion about EFI etc. but this set of instructions seems to suggest it should Just Work, and it doesn't. Help? I'm increasingly unhappy with the more locked-down approach Apple is taking, and I'd quite like to start using Linux with a view to transitioning over to using it as my main operating system, but booting from the CD takes forever, runs slowly and I'm really hoping to get it moving off USB. Can anybody help me?

  • Why can't I use Unity 3D on a ATI Mobility Radeon HD 4200 Series with FGLRX drivers?

    - by user88257
    With a brand new install of 12.04 on my Dell Inspiron M5030, Unity 3D appears to load everything but the icons in the top left, and I am unable to click on anything. Unity 2D seems to works fine however. I have done nothing except install Synaptic Package manager and follow this guide to install FGLRX Drivers under Settings ? Additional Drivers, the driver shows as installed and functioning. Also after running: /usr/lib/nux/unity_support_test -p, I get this: OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Mobility Radeon HD 4200 Series OpenGL version string: 3.3.11653 Compatibility Profile Context Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes I am unsure as to what the problem is. I have tried the non-proprietary drivers, I could not get them to work either, but I would be willing to try again.

  • Diagram to show code responsibility

    - by Mike Samuel
    Does anyone know how to visually diagram the ways in which the flow of control in code passes between code produced by different groups and how that affects the amount of code that needs to be carefully written/reviewed/tested for system properties to hold? What I am trying to help people visualize are arguments of the form: For property P to hold, nd developers have to write application code, Ca, without certain kinds of errors, and nm maintainers have to make sure that the code continues to not have these kinds of errors over the project lifetime. We could reduce the error rate by educating nd developers and nm maintainers. For us to be confident that the property holds, ns specialists still need to test or check |Ca| lines of code and continue to test/check the changes by nm maintainers. Alternatively, we could be confident that P holds if all code paths that could violate P went through tool code, Ct, written by our specialists. In our case, test suites alone cannot give confidence that P holdsnd » nsnm ns|Ca| » |Ct| so writing and maintaining Ct is economical, frees up our developers to worry about other things, and reduces the ongoing education commitment by our specialists. or those conditions do not hold, so focusing on education and testing is preferable. Example 1 As a concrete example, suppose we want to ensure that our web-service only produces valid JSON output. Our web-service provides several query and mutation operators that can be composed in interesting ways. We could try to educate everyone who maintains those operations about the JSON syntax, the importance of conformance, and libraries available so that when they write to an output buffer, every possible sequence of appends results in syntactically valid JSON. Alternatively, we don't expose an output stream handle to application code, and instead expose a JSON sink so that every code path that writes a response is channeled through a JSON sink that is written and maintained by a specialist who knows JSON syntax and can use well-written libraries to produce only valid output. Example 2 We need to make sure that a service that receives a URL from an untrusted source and tries to fetch its content does not end up revealing sensitive files from the file-system, like file:///etc/passwd. If there is a single standard way that any developer familiar with the application language's libraries would use to fetch URLs, which has file-system access turned off by default, then simply educating developers about the standard mechanism, and testing that file probing fails for some inputs, will probably be sufficient.

  • Broken Links in different browsers

    - by kdorival
    Hi I'm having problems with our website, http://www.accessiblehomehealthcare.com, which is a wordpress 2.7 (version). All of a sudden our RSS links broke on the right side, which has happened before and I fixed it within 5 mins. Now, when I fix it, it doesn't look right in different version of I.E. or Firefox, I have I.E. 8 and Firefox 3.6.15 and it looks good for the most part, but there are a few parts where the links are broken. One browser the links would look ok but go to another page and the links or logos would be broken. Certain parts of the website should be static(identical) to the other pages of the site, but if a link is broken on one page, its perfect on another page. I was wondering was there a secret code for wordpress to keep the sites compatible with all browser versions or is there a bigger issue???? Any help or suggestions will help???

  • Helper method to Replace/Remove characters that do not match the Regular Expression

  • Drawing on a webpage – HTML5 - IE9

    - by nmarun
    So I upgraded to IE9 and continued exploring HTML5. Now there’s this ‘thing’ called Canvas in HTML5 with which you can do some cool stuff. Alright what IS this Canvas thing anyways? The Web Hypertext Application Technology Working Group says this: “The canvas element provides scripts with a resolution-dependent bitmap canvas, which can be used for rendering graphs, game graphics, or other visual images on the fly.” The Canvas element has two only attributes – width and height and when not specified they take up the default values of 300 and 150 respectively. Below is what my HTML file looks like: 1: <!DOCTYPE html> 2: <html lang="en-US"> 3: <head> 4: <script type="text/javascript" src="CustomScript.js"></script> 5: <script src="jquery-1.4.4.js" type="text/javascript"></script 6:  7: <title>Draw on a webpage</title> 8: </head> 9: <body> 10: <canvas id="canvas" width="500" height="500"></canvas> 11: <br /> 12: <input type="submit" id="submit" value="Clear" /> 13: <h4 id="currentPosition"> 14: 0, 0 15: </h4> 16: <div id="mousedownCoords"></div> 17: </body> 18: </html> In case you’re wondering, this is not a MVC or any kind of web application. This is plain ol’ HTML even though I’m writing all this in VS 2010. You see this is a very simple, ‘gimmicks-free’ html page. I have declared a Canvas element on line 10 and a button on line 11 to clear the drawing board. I’m using jQuery / JavaScript show the current position of the mouse on the screen. This will get updated in the ‘currentPosition’ <h4> tag and I’m using the ‘mousedownCoords’ to write all the places where the mouse was clicked. This is what my page renders as: The rectangle with a background is our canvas. The coloring is due to some javascript (which we’ll see in a moment). Now let’s get to our CustomScript.js file. 1: jQuery(document).ready(function () { 2: var isFirstClick = true; 3: var canvas = document.getElementById("canvas"); 4: // getContext: Returns an object that exposes an API for drawing on the canvas 5: var canvasContext = canvas.getContext("2d"); 6: fillBackground(); 7:  8: $("#submit").click(function () { 9: clearCanvas(); 10: fillBackground(); 11: }); 12:  13: $(document).mousemove(function (e) { 14: $('#currentPosition').html(e.pageX + ', ' + e.pageY); 15: }); 16: $(document).mouseup(function (e) { 17: // on the first click 18: // set the moveTo 19: if (isFirstClick == true) { 20: canvasContext.beginPath(); 21: canvasContext.moveTo(e.pageX - 7, e.pageY - 7); 22: isFirstClick = false; 23: } 24: else { 25: // on subsequent clicks, draw a line 26: canvasContext.lineTo(e.pageX - 7, e.pageY - 7); 27: canvasContext.stroke(); 28: } 29:  30: $('#mousedownCoords').text($('#mousedownCoords').text() + '(' + e.pageX + ',' + e.pageY + ')'); 31: }); 32:  33: function fillBackground() { 34: canvasContext.fillStyle = '#a1b1c3'; 35: canvasContext.fillRect(0, 0, 500, 500); 36: canvasContext.fill(); 37: } 38:  39: function clearCanvas() { 40: // wipe-out the canvas 41: canvas.width = canvas.width; 42: // set the isFirstClick to true 43: // so the next shape can begin 44: isFirstClick = true; 45: // clear the text 46: $('#mousedownCoords').text(''); 47: } 48: })   The script only looks long and complicated, but is not. I’ll go over the main steps. Get a ‘hold’ of your canvas object and retrieve the ‘2d’ context out of it. On mousemove event, write the current x and y coordinates to the ‘currentPosition’ element. On mouseup event, check if this is the first time the user has clicked on the canvas. The coloring of the canvas is done in the fillBackground() function. We first need to start a new path. This is done by calling the beginPath() function on our context. The moveTo() function sets the starting point of our path. The lineTo() function sets the end point of the line to be drawn. The stroke() function is the one that actually draws the line on our canvas. So if you want to play with the demo, here’s how you do it. First click on the canvas (nothing visible happens on the canvas). The second click draws a line from the first click to the current coordinates and so on and so forth. Click on the ‘Clear’ button, to reset the canvas and to give your creativity a clean slate. Here’s a sample output: Happy drawing! Verdict: HTML5 and IE9 – I think we’re on to something big and great here!

  • IRM Item Codes &ndash; what are they for?

    - by martin.abrahams
    A number of colleagues have been asking about IRM item codes recently – what are they for, when are they useful, how can you control them to meet some customer requirements? This is quite a big topic, but this article provides a few answers. An item code is part of the metadata of every sealed document – unless you define a custom metadata model. The item code is defined when a file is sealed, and usually defaults to a timestamp/filename combination. This time/name combo tends to make item codes unique for each new document, but actually item codes are not necessarily unique, as will become clear shortly. In most scenarios, item codes are not relevant to the evaluation of a user’s rights - the context name is the critical piece of metadata, as a user typically has a role that grants access to an entire classification of information regardless of item code. This is key to the simplicity and manageability of the Oracle IRM solution. Item codes are occasionally exposed to users in the UI, but most users probably never notice and never care. Nevertheless, here is one example of where you can see an item code – when you hover the mouse pointer over a sealed file. As you see, the item code for this freshly created file combines a timestamp with the file name. But what are item codes for? The first benefit of item codes is that they enable you to manage exceptions to the policy defined for a context. Thus, I might have access to all oracle – internal files - except for 2011_03_11 13:33:29 Board Minutes.sdocx. This simple mechanism enables Oracle IRM to provide file-by-file control where appropriate, whilst offering the scalability and manageability of classification-based control for the majority of users and content. You really don’t want to be managing each file individually, but never say never. Item codes can also be used for the opposite effect – to include a file in a user’s rights when their role would ordinarily deny access. So, you can assign a role that allows access only to specified item codes. For example, my role might say that I have access to precisely one file – the one shown above. So how are item codes set? In the vast majority of scenarios, item codes are set automatically as part of the sealing process. The sealing API uses the timestamp and filename as shown, and the user need not even realise that this has happened. This automatically creates item codes that are for all practical purposes unique - and that are also intelligible to users who might want to refer to them when viewing or assigning rights in the management UI. It is also possible for suitably authorised users and applications to set the item code manually or programmatically if required. Setting the item code manually using the IRM Desktop The manual process is a simple extension of the sealing task. An authorised user can select the Advanced… sealing option, and will see a dialog that offers the option to specify the item code. To see this option, the user’s role needs the Set Item Code right – you don’t want most users to give any thought at all to item codes, so by default the option is hidden. Setting the item code programmatically A more common scenario is that an application controls the item code programmatically. For example, a document management system that seals documents as part of a workflow might set the item code to match the document’s unique identifier in its repository. This offers the option to tie IRM rights evaluation directly to the security model defined in the document management system. Again, the sealing application needs to be authorised to Set Item Code. The Payslip Scenario To give a concrete example of how item codes might be used in a real world scenario, consider a Human Resources workflow such as a payslips. The goal might be to allow the HR team to have access to all payslips, but each employee to have access only to their own payslips. To enable this, you might have an IRM classification called Payslips. The HR team have a role in the normal way that allows access to all payslips. However, each employee would have an Item Reader role that only allows them to access files that have a particular item code – and that item code might match the employee’s payroll number. So, employee number 123123123 would have access to items with that code. This shows why item codes are not necessarily unique – you can deliberately set the same code on many files for ease of administration. The employees might have the right to unseal or print their payslip, so the solution acts as a secure delivery mechanism that allows payslips to be distributed via corporate email without any fear that they might be accessed by IT administrators, or forwarded accidentally to anyone other than the intended recipient. All that remains is to ensure that as each user’s payslip is sealed, it is assigned the correct item code – something that is easily managed by a simple IRM sealing application. Each month, an employee’s payslip is sealed with the same item code, so you do not need to keep amending the list of items that the user has access to – they have access to all documents that carry their employee code.

  • Twig Code Completion

    - by Ondrej Brejla
    Hi all! After few weeks we have a new feature for you which will be available in upcoming NetBeans 7.3. It's about new code completion in Twig files! So let us introduce it a bit. Now we hopefully support all of Twig built-in elements. It means Tags, Filters, Functions, Tests and Operators (see Twig documentation for more information). All elements are also documented, so if you don't know what which element does, just read it in the IDE documentation window! We try to resolve some Completion Context to suggest you only the most corresponding element types, but it's not so visible, since almost everything can be used everywhere in Twig files ;) And that's all for today and as usual, please test it and if you find something strange, don't hesitate to file a new issue (product php, component Twig). Thanks a lot!

  • Convert Docx or Odt to Pdf

    - by luxifer
    Hi there, I need to find a way to convert docx or odt files to pdf on a linux web server. Therefore I'm not willing to install openoffice.org for obvious reasons. I've tried Google but it failed for me, so I'm here :-) I can't imagine there's no other solution to this problem than to install a huge chunk of binaries given that a) there are (or at least should be) lot's of packages which can read docx or at least odt and b) there are as many packages which can write pdf files What am I missing here? scratching head Regards, luxifer ps edit: I don't want to use a web service - neither free or paid edit 2: at this point it would also help to convert the docx back to doc so I could use wvpdf to generate the pdf... edit 3: of course it would also help if i could do search and replace on a doc file in the first place; or xps for that matter

  • Reading train stop display names from a resource bundle

    - by Frank Nimphius
    v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Normal 0 false false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif";} In Oracle JDeveloper 11g R1, you set the display name of a train stop of an ADF bounded task flow train model by using the Oracle JDeveloper Structure Window. To do so Double-click onto the bounded task flow configuration file (XML) located in the Application Navigator so the task flow diagram open In the task flow diagram, select the view activity node for which you want to define the display name. In the Structure Window., expand the view activity node and then the train-stop node therein Add the display name element by using the right-click context menu on the train-stop node, selecting Insert inside train-stop > Display Name Edit the Display Name value with the Property Inspector Following the steps outlined above, you can define static display names – like "PF1" for page fragment 1 shown in the image below - for train stops to show at runtime. In the following, I explain how you can change the static display string to a dynamic string that reads the display label from a resource bundle so train stop labels can be internationalized. There are different strategies available for managing message bundles within an Oracle JDeveloper project. In this blog entry, I decided to build and configure the default properties file as indicated by the projects properties. To learn about the suggested file name and location, open the JDeveloper project properties (use a right mouse click on the project node in the Application Navigator and choose Project Properties. Select the Resource Bundle node to see the suggested name and location for the default message bundle. Note that this is the resource bundle that Oracle JDeveloper would automatically create when you assign a text resource to an ADF Faces component in a page. For the train stop display name, we need to create the message bundle manually as there is no context menu help available in Oracle JDeveloper. For this, use a right mouse click on the JDeveloper project and choose New | General | File from the menu and in the opened dialog. Specify the message bundle file name as the name looked up before in the project properties Resource Bundle option. Also, ensure that the file is saved in a directory structure that matches the package structure shown in the Resource Bundle dialog. For example, you would save the properties file in the View Project's src > adf > sample directory if the package structure was "adf.sample" (adf.sample.ViewControllerBundle). Edit the properties file and define key – values pairs for the train stop component. In the sample, such key value pairs are TrainStop1=Train Stop 1 TrainStop2=Train Stop 2 TrainStop3=Train Stop 3 Next, double click the faces-config.xml file and switch the opened editor to the Overview tab. Select the Application category and press the green plus icon next to the Resource Bundle section. Define the resource bundle Base Name as the package and properties file name, for example adf.sample.ViewControllerBundle Finally, define a variable name for the message bundle so the bundle can be accessed from Expression Language. For this blog example, the name is chosen as "messageBundle". <resource-bundle>   <base-name>adf.sample.ViewControllerBundle</base-name>   <var>messageBundle</var> </resource-bundle> Next, select the display-name element in the train stop node (similar to when creating the display name) and use the Property Inspector to change the static display string to an EL expression referencing the message bundle. For example: #{messageBundle.TrainStop1} At runtime, the train stops now show display names read from a message bundle (the properties file).
