• New Whitepaper: Evolution from the Traditional Data Center to Exalogic: An Operational Perspective

  - by Javier Puerta

  IT organizations are struggling with the need to balance the day-to-day concerns of data center management against the business level requirements to deliver long-term value. This balancing act has proven difficult and inefficient: systems and application management tools are resource intensive and traditional infrastructure management architectures have developed over time on a project by project basis. These traditional management systems consist of multiple tools that require administrators to waste time performing too many steps to handle routine administrative tasks. Operational efficiency and agility in your enterprise are directly linked to the capabilities provided by the management layer across the entire stack, from the application, middleware, operating system, compute, network and storage. Only when this end to end capability is provided will we experience the full benefit of a scalable, efficient, responsive and secure datacenter. Managing Exalogic is substantially less complex and error prone than managing traditional systems built from individually sourced, multi-vendor components because Exalogic is designed to be administered and maintained as a single, integrated system (Figure 1). It is at the forefront of the industry-wide shift away from costly and inferior one-off platforms toward private clouds and Engineered Systems.

• Project Time Tracker

  - by Geertjan

  Based on yesterday's blog entry, let's do something semi useful and display, in the project popup, which is available when you right-click a project in the Projects window, the time since the last change was made anywhere in the project, i.e., we can listen recursively to any changes done within a project and then update the popup with the newly acquired information, dynamically: import java.awt.event.ActionEvent; import java.text.DateFormat; import java.text.SimpleDateFormat; import java.util.ArrayList; import java.util.Collection; import java.util.List; import javax.swing.AbstractAction; import org.netbeans.api.project.Project; import org.netbeans.api.project.ProjectUtils; import org.openide.awt.ActionID; import org.openide.awt.ActionReference; import org.openide.awt.ActionRegistration; import org.openide.awt.StatusDisplayer; import org.openide.filesystems.FileAttributeEvent; import org.openide.filesystems.FileChangeListener; import org.openide.filesystems.FileEvent; import org.openide.filesystems.FileRenameEvent; import org.openide.util.Lookup; import org.openide.util.LookupEvent; import org.openide.util.LookupListener; import org.openide.util.Utilities; import org.openide.util.WeakListeners; @ActionID( category = "Demo", id = "org.ptt.TrackProjectSelectionAction") @ActionRegistration( lazy = false, displayName = "NOT-USED") @ActionReference( path = "Projects/Actions", position = 0) public final class TrackProjectSelectionAction extends AbstractAction implements LookupListener, FileChangeListener { private Lookup.Result<Project> projects; private Project context; private Long startTime; private Long changedTime; private DateFormat formatter; private List<Project> timedProjects; public TrackProjectSelectionAction() { putValue("popupText", "Timer"); formatter = new SimpleDateFormat("HH:mm:ss"); timedProjects = new ArrayList<Project>(); projects = Utilities.actionsGlobalContext().lookupResult(Project.class); projects.addLookupListener( WeakListeners.create(LookupListener.class, this, projects)); resultChanged(new LookupEvent(projects)); } @Override public void resultChanged(LookupEvent le) { Collection<? extends Project> allProjects = projects.allInstances(); if (allProjects.size() == 1) { Project currentProject = allProjects.iterator().next(); if (!timedProjects.contains(currentProject)) { String currentProjectName = ProjectUtils.getInformation(currentProject).getDisplayName(); putValue("popupText", "Start Timer for Project: " + currentProjectName); StatusDisplayer.getDefault().setStatusText( "Current Project: " + currentProjectName); timedProjects.add(currentProject); context = currentProject; } } } @Override public void actionPerformed(ActionEvent e) { refresh(); } protected void refresh() { startTime = System.currentTimeMillis(); String formattedStartTime = formatter.format(startTime); putValue("popupText", "Timer started: " + formattedStartTime + " (" + ProjectUtils.getInformation(context).getDisplayName() + ")"); } @Override public void fileChanged(FileEvent fe) { changedTime = System.currentTimeMillis(); formatter = new SimpleDateFormat("mm:ss"); String formattedLapse = formatter.format(changedTime - startTime); putValue("popupText", "Time since last change: " + formattedLapse + " (" + ProjectUtils.getInformation(context).getDisplayName() + ")"); startTime = changedTime; } @Override public void fileFolderCreated(FileEvent fe) {} @Override public void fileDataCreated(FileEvent fe) {} @Override public void fileDeleted(FileEvent fe) {} @Override public void fileRenamed(FileRenameEvent fre) {} @Override public void fileAttributeChanged(FileAttributeEvent fae) {} } Some more work needs to be done to complete the above, i.e., for each project you somehow need to maintain the start time and last change and redisplay that whenever the user right-clicks the project.

• Access Control Lists for Roles

  - by Kyle Hatlestad

  Back in an earlier post, I wrote about how to enable entity security (access control lists, aka ACLs) for UCM 11g PS3.  Well, there was actually an additional security option that was included in that release but not fully supported yet (only for Fusion Applications).  It's the ability to define Roles as ACLs to entities (documents and folders).  But now in PS5, this security option is now fully supported.   [Read More]

• Exiting a reboot loop

  - by user12617035

  If you're in a situation where the system is panic'ing during boot, you can use # boot net -s to regain control of your system. In my case, I'd added some diagnostic code to a (PCI) driver (that is used to boot the root filesystem). There was a bug in the driver, and each time during boot, the bug occurred, and so caused the system to panic: ... 000000000180b950 genunix:vfs_mountroot+60 (800, 200, 0, 185d400, 1883000, 18aec00) %l0-3: 0000000000001770 0000000000000640 0000000001814000 00000000000008fc %l4-7: 0000000001833c00 00000000018b1000 0000000000000600 0000000000000200 000000000180ba10 genunix:main+98 (18141a0, 1013800, 18362c0, 18ab800, 180e000, 1814000) %l0-3: 0000000070002000 0000000000000001 000000000180c000 000000000180e000 %l4-7: 0000000000000001 0000000001074800 0000000000000060 0000000000000000 skipping system dump - no dump device configured rebooting... If you're logged in via the console, you can send a BREAK sequence in order to gain control of the firmware's (OBP's) prompt. Enter Ctrl-Shift-[ in order to get the TELNET prompt. Once telnet has control, enter this: telnet> send brk You'll be presented with OBP's prompt: ok You then enter the following in order to boot into single-user mode via the network: ok boot net -s Note that booting from the network under Solaris will implicitly cause the system to be INSTALLED with whatever software had last been configured to be installed. However, we are using boot net -s as a "handle" with which to get at the Solaris prompt. Once at that prompt, we can perform actions as root that will let us back out our buggy driver (ok...

• The (non) Importance of Language

  - by Eric A. Stephens

  Working with a variety of clients on EA initiatives one begins to realize that not everyone is a fan of EA. Specifically, they are not a fan of the "a-word". Some organizations have abused this term with creating and assigning the title to just about anyone who demonstrates above average prowess with a particular technology. Other organizations will assign the title to those managers left with no staff after a reorg. Some companies, unfortunately, have simply had a bad go of it with regard to EA...or any "A" for that matter. What we call "EA" is almost irrelevant. But what is not negotiable for those to succeed in business is to manage change. That is what EA is all about. I recall sitting in Zachman training led by himself. He posits the only organizations that don't need EA (or whatever you want to call it) are those that are not changing. My experience suggests those orgs that aren't changing aren't growing. And if you aren't growing, you're dying. Any EA program will not succeed unless there is a desire to change. No desire to change suggests the EA/Advisor/Change Agent should just walk the other way.

• How to Get Vim to do Filename Completion Even When You are Root

  - by user12608033

  From the Obscure Unix Admin Tip of the Day section... If you occasionally edit files as root (I never do, I always use pfexec, wink wink), then you may have noticed that the vim (Vi Improved) editor that normally does filename completion via the <Tab> key now gives you something like: :e /etc/mo^I when you try to open up /etc/motd with a little less typing So, there are at least three solutions to this: Use <Ctrl>-E instead of <Tab> Use the "-N" flag when you start Vim :set wildchar=<Tab> (Enter those 5 characters, not an actual Tab) The reason for this? It seems that when you are root, Vim sets it's "compatible" flag, which makes it behave more like its ancestor vi. In turn this makes Vim set 'wildchar' to <Ctrl>-E. For more info, read the section you get when you enter :help cmdline-completion

• Play in NetBeans IDE (Part 2)

  - by Geertjan

  Peter Hilton was one of many nice people I met for the first time during the last few days constituting JAX London. He did a session today on the Play framework which, if I understand it correctly, is an HTML5 framework. It doesn't use web.xml, Java EE, etc. It uses Scala internally, as well as in its templating language.  Support for Play would, I guess, based on the little I know about it right now, consist of extending the HTML5 application project, which is new in NetBeans IDE 7.3. The workflow I imagine goes as follows. You'd create a new HTML5 application project, at which point you can choose a variety of frameworks and templates (Coffee Script, Angular, etc), which comes out of the box with the HTML5 support (i.e., Project Easel) in NetBeans IDE 7.3. Then, once the project is created, you'll right-click it and go to the Project Properties dialog, where you'll be able to enable Play support: At this stage, i.e., when you've checked the checkbox above and then clicked OK, all the necessary Play files will be added to your project, e.g., the routes file and the application.conf, for example. And then you have a Play application. Creating support in this way entails nothing more than creating a module that looks like this, i.e., with one Java class, where even the layer.xml file below is superfluous: All the code in the PlayEnablerPlanel.java that you see above is as follows: import java.awt.BorderLayout; import javax.swing.JCheckBox; import javax.swing.JComponent; import javax.swing.JPanel; import org.netbeans.spi.project.ui.support.ProjectCustomizer; import org.netbeans.spi.project.ui.support.ProjectCustomizer.Category; import org.openide.util.Lookup; public class PlayEnablerPanel implements ProjectCustomizer.CompositeCategoryProvider {     @ProjectCustomizer.CompositeCategoryProvider.Registration(             projectType = "org.netbeans.modules.web.clientproject",             position = 1000)     public static PlayEnablerPanel enablePlay() {         return new PlayEnablerPanel();     }     @Override     public Category createCategory(Lookup lkp) {         return ProjectCustomizer.Category.create("Play Framework", "Configure Play", null);     }     @Override     public JComponent createComponent(Category ctgr, Lookup lkp) {         JPanel playPanel = new JPanel(new BorderLayout());         playPanel.add(new JCheckBox("Enable Play"), BorderLayout.NORTH);         return playPanel;     } } Looking forward to having a beer with Peter soon (he lives not far away, in Rotterdam) to discuss this! Also read Part 1 of this series, which I wrote some time ago, and which has other ideas and considerations.

• RPi and Java Embedded GPIO: It all begins with hardware

  - by hinkmond

  So, you want to connect low-level peripherals (like blinky-blinky LEDs) to your Raspberry Pi and use Java Embedded technology to program it, do you? You sick foolish masochist. No, just kidding! That's awesome! You've come to the right place. I'll step you though it. And, as with many embedded projects, it all begins with hardware. So, the first thing to do is to get acquainted with the GPIO header on your RPi board. A "header" just means a thingy with a bunch of pins sticking up from it where you can connect wires. See the the red box outline in the photo. Now, there are many ways to connect to that header outlined by the red box in the photo (which the RPi folks call the P1 header). One way is to use a breakout kit like the one at Adafruit. But, we'll just use jumper wires in this example. So, to connect jumper wires to the header you need a map of where to connect which wire. That's why you need to study the pinout in the photo. That's your map for connecting wires. But, as with many things in life, it's not all that simple. RPi folks have made things a little tricky. There are two revisions of the P1 header pinout. One for older boards (RPi boards made before Sep 2012), which is called Revision 1. And, one for those fancy 512MB boards that were shipped after Sep 2012, which is called Revision 2. So, first make sure which board you have: either you have the Model A or B with 128MB or 256MB built before Sep 2012 and you need to look at the pinout for Rev. 1, or you have the Model B with 512MB and need to look at Rev. 2. That's all you need for now. More to come... Hinkmond

• Two Hidden NetBeans Keyboard Shortcuts for Opening & Toggling between Views

  - by Geertjan

  The following are two really basic shortcuts for working with NetBeans editor windows that will be added to the Keyboard Shortcuts card for NetBeans IDE 7.2: Ctrl-Alt-PgUp/PgDown: Shortcuts for switching between editor types (e.g. Source, Design, History buttons). Switching between the editor types is a frequent operation sometimes, e.g., when using GUI builder, and while it can be done easily via mouse, or from View | Editors menu, it is very handy to know the shortcuts as well. Ctrl-PgUp/PgDown: Similarly, these are shortcuts for switching to next/previous opened document (tab). Note this is not like Ctrl-Tab that cycles in the last used order, but going through the tabs as they appear in the editor. Both shortcuts should fit into the "Opening and Toggling between Views" section. These are important to mention on the card because they are not visible anywhere else in the UI (as there are no menu items like "Go to next/previous editor type" or "Go to next/previous document"). Reported by Tomas Pavek from the NetBeans Team, here: http://netbeans.org/bugzilla/show_bug.cgi?id=213815

• HTML Manifest for Content Folios

  - by Kyle Hatlestad

  I recently worked on a project to create a custom content folio renderer in WebCenter Content. It needed to output the native files in the folio along with a manifest file in HTML format which would list the contents of the folio along with any designated metadata and a relative link to the file within the download.  This way a person could hand someone the folio download and it would be a self-contained package with all of the content and a single file to display the information on the contents.  The default Zip rendition of the folio will output the web-viewable version of the file with an HDA formatted file for each one. And unless you are fluent in HDA or have a tool to read them, they are difficult to consume. [Read More]

• HTML Manifest for Content Folios

  - by Kyle Hatlestad

  I recently worked on a project to create a custom content folio renderer in WebCenter Content. It needed to output the native files in the folio along with a manifest file in HTML format which would list the contents of the folio along with any designated metadata and a relative link to the file within the download.  This way a person could hand someone the folio download and it would be a self-contained package with all of the content and a single file to display the information on the contents.  The default Zip rendition of the folio will output the web-viewable version of the file with an HDA formatted file for each one. And unless you are fluent in HDA or have a tool to read them, they are difficult to consume. I thought this might be useful for others, so I'm posting a copy of the component here. Beyond the standard instructions for installing a component, there is an environment configuration file (folionativezipwithmanifestrenderer_environment.cfg) which has a couple of options. FolioMetadataManifestList - This is a comma separated list of metadata fields (system or custom) that should be included in the manifest file. FolioMetadataManifestUseOriginalFilename - (True or False) If set to True, the filenames in the zip file will be based on the original filename as it was checked into WebCenter Content.  If False, it will use the 'Name' of the item as defined within the Folio.  This is usually the Title of the item. The component also includes the source code, so feel free to use this as a reference for creating other interesting folios.

• 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.

• Two Sessions All Humans Should Watch Right Now

  - by Geertjan

  At conferences, I definitely prefer technical sessions over any other kind of session. That's partly because I want to walk away from a conference with new libraries and APIs to play with, such as the AT&T ARO tool that I've been blogging about over the past few days thanks to being introduced to it in a great session by Doug Sillars at Oredev, in Malmo, Sweden. I only say the above to set the scene. And the scene is that I avoid sessions that deal with "agile topics" or whatever that means. I mean those sessions where you're meant to reflect on some way you're developing nothing in particular and then come away with new ways of doing that. I avoid those. Not because I don't necessarily like those or think I have nothing to learn, both of which I don't (or do, depending on how you read double negatives), but because there are so many sessions to attend that I focus on those that actually give me more technical knowledge that I can do something with immediately. Having said all that, here's two absolutely wonderful sessions (and probably many more but I really liked these two) presented at Oredev over the last few days, one by JB Rainsberger and the other by Woody Zuill, both very nice people who I met for the first time during the last few days, and who aren't paying me to promote them, and who're still struggling to figure out how to say my name. Whether you're a developer or manager or whatever you are, take this on trust, and simply watch these screencasts, hey, at most you're going to lose two hours of your life that you would've spent doing something else: Speaking for myself, I'm going to be watching both these presentations again several times in my life, that's for sure.

• GeoTools Demo Embedded in an Application Framework via Maven

  - by Geertjan

  GeoTools 8.4 was very recently released, according to its active blog, and to celebrate here's a starting point for working with GeoTools on the NetBeans Platform: The sources of the above are below, as a Maven project, so this project can be used in any IDE or command line: http://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.3/tutorials/geospatial/geotools/MyGeospatialSystem Though quite dated, the GeoTools NetBeans Quick Start is very helpful, especially since it used Maven too, but not the NetBeans Platform, unlike the above sample. From the point of view of NetBeans Platform developers, the GeoTools JMapPane class is very useful, providing the integration point between GeoTools and the rest of the NetBeans Platform application. Being integrated into the NetBeans Platform means that a host of standard features are now available to the GeoTools features, e.g., print functionality, which only requires a runtime dependency on the NetBeans Print API, together with the "print.printable" client property put into constructor of the TopComponent: By the way, I've spent some time now and again being confused about the difference between GeoTools and GeoToolkit. Here's an interesting starting point to beginning to understand the differences and history between them. Soon I'd like to have an example similar for the above for GeoToolkit.

• Dark NetBeans

  - by Geertjan

  Let's make NetBeans IDE look like this. Not saying it's a nice color or anything, just that it's possible to do so: I changed the coloring in the Java editor by going to Tools | Options, then chose "Fonts & Colors", then selected the "Norway Today" profile and changed the background setting to Dark Gray. Next, I put this themes.xml file into the "config" folder of the NetBeans IDE user directory, which you can identify as such by going to Help | About in the IDE. Go to the exact location defined by "User directory" in Help | About, and then go to the "config" folder within that folder: The "config" folder of the user directory is the readable/writable root of the NetBeans IDE virtual filesystem. If a themes.xml file is found there, it is used, as described here. Then, in netbeans.conf file, which is not in the NetBeans user directory but in the NetBeans installation directory, within its "etc" folder, I added the following to "netbeans_default_options": -J-Dnetbeans.useTheme=true --laf Metal The first of these enables usage of the themes.xml file, i.e., it notifies NetBeans IDE at startup to load the themes.xml file and to apply the content to the relevant UI components, while the second is needed because most/all of the themes only work if you're using the Metal Look and Feel. Note: I must add that in most cases, whatever it is you're trying to achieve via a themes.xml file can probably be achieved in a different, and better, way. The themes.xml mechanism has been there forever, but is not actively supported or tested, though it may work for the specific thing you're trying to do anyway. For example, if you're trying to change the background color of a TopComponent, use the paintComponent method of the TopComponent instead of using a themes.xml file.
