• 12c - Silly little trick with invisibility...

  - by noreply(at)blogger.com (Thomas Kyte)

  This is interesting, if you hide and then unhide a column - it will end up at the "end" of the table.  Consider:ops$tkyte%ORA12CR1> create table t ( a int, b int, c int );Table created.ops$tkyte%ORA12CR1>ops$tkyte%ORA12CR1> desc t; Name                                                  Null?    Type ----------------------------------------------------- -------- ------------------------------------ A                                                              NUMBER(38) B                                                              NUMBER(38) C                                                              NUMBER(38)ops$tkyte%ORA12CR1> alter table t modify (a invisible);Table altered.ops$tkyte%ORA12CR1> alter table t modify (a visible);Table altered.ops$tkyte%ORA12CR1> desc t; Name                                                  Null?    Type ----------------------------------------------------- -------- ------------------------------------ B                                                              NUMBER(38) C                                                              NUMBER(38) A                                                              NUMBER(38)Now, that means you can add a column or shuffle them around.  What if we had just added A to the table and really really wanted A to be first.  My first approach would be "that is what editioning views are great at".  If I couldn't use an editioning view for whatever reason - we could shuffle the columns:ops$tkyte%ORA12CR1> alter table t modify (b invisible);Table altered.ops$tkyte%ORA12CR1> alter table t modify (c invisible);Table altered.ops$tkyte%ORA12CR1> alter table t modify (b visible);Table altered.ops$tkyte%ORA12CR1> alter table t modify (c visible);Table altered.ops$tkyte%ORA12CR1>ops$tkyte%ORA12CR1> desc t; Name                                                  Null?    Type ----------------------------------------------------- -------- ------------------------------------ A                                                              NUMBER(38) B                                                              NUMBER(38) C                                                              NUMBER(38)Note: that could cause some serious invalidations in your database - so make sure you are a) aware of that b) willing to pay that penalty and c) really really really want A to be first in the table!

• Lookup Viewer

  - by Geertjan

  The Maven integrated view that I showed yesterday I was able to create because I happened to know that an implementation of SubprojectProvider and LogicalViewProvider are in the Lookup of Maven projects. With that knowledge, I was able to use and even delegate to those implementations. But what if you don't know that those implementations are in the Lookup of the Project object? In the case of the Maven Project implementation, you could look in the source code of the Maven Project implementation, at the "getLookup" method. However, any other module could be putting its own objects into that Lookup, dynamically, i.e., at runtime. So there's no way of knowing what's in the Lookup of any Project object or any other object with a Lookup. But now imagine that you have a Lookup Viewer, as a tool during development, which you would exclude when distributing the application. Whenever new objects are found in the Lookup, the viewer displays them. You could install the Lookup Viewer into NetBeans IDE, or any other NetBeans Platform application, and then get a quick impression of what's actually in the Lookup when you select a different item in the application during development. Here it is (though I vaguely remember someone else writing something similar): Above, a Maven Project is selected. The Lookup Window shows that, among many other classes, an implementation of SubprojectProvider and LogicalViewProvider are found in the Lookup when the Maven Project is selected. If an item in the Lookup Window has its own Lookup, the content of that Lookup is displayed as child nodes of the Lookup, etc, i.e., you can explore all the way down the Lookup of each item found within objects found within the current selection. (What's especially fun is seeing the SaveCookieImpl being added and removed from the Lookup Window when you make/save a change in a document.) Another example is below, showing the Lookup Window installed in a custom application created during a course at MIT in Boston: A small trick I had to apply is that I always show the previous Lookup, since the current Lookup, when you select one of the Nodes in the Lookup Window, would be the Lookup of the Lookup Window itself! If anyone is interested in this, I can publish the NetBeans module providing the above window to the NetBeans update center.

• Groovy JUnit test support

  - by Martin Janicek

  Good news everyone! I've implemented support for the Groovy JUnit tests which basically means you can finally use Groovy in the area where is so highly productive! You can create a new Groovy JUnit test in the New File/Groovy/Groovy JUnit test and it should behave in the same way as for Java tests. Which means if there is no JUnit setup in your project yet, you can choose between JUnit 3 and JUnit 4 template and with respect to your choice the project settings will be changed (in case of the Maven based projects the correct dependencies and plugins are added to the pom.xml and in case of the Ant based project the JUnit dependency is configured). Or if the project is already configured, the correct template will be used. After that the test skeleton is created and you can write your own code and of course run the tests together with the java ones. Some of you were asking for this feature and of course I don't expect it will be perfect from the beginning so I would be really glad to see some constructive feedback about what could be improved and/or redesigned ;] ..at the end I have to say that the feature is not active for the Ant based Java EE projects yet (I'm aware of it and it will be fixed to the NetBeans 7.3 final - actually it will be done in a few days/weeks, just want you to know). But it's already complete in all types of the Maven based projects and also for the Ant based J2SE projects. And as always, the daily build where you can try the feature can be downloaded right here, so don't hesitate to try it!

• Subdomain redirects to different server, maintaining original URL

  - by Jason Baker

  I just took over the webmaster position in my organization, and I'm trying to set up a development environment separate from the production environment. The two environments are hosted with different companies, both on shared hosting plans. Right now, production is at domain.com and development is at domain2.com What I want is to direct my development team to dev.domain.com More importantly, I don't want the URL to change from dev.domain.com back to domain2.com, but I also be responsive to page changes. For example, if my dev team navigates from dev.domain.com to a page (called "page"), I'd like the URL to show as dev.domain.com/page Is this possible, or am I just dreaming?

• Freescale One Box Unboxing (then installing Java SE Embedded technology)

  - by hinkmond

  So, I get a FedEx delivery the other day... "What cool device could be inside this FedEx Overnight Express Large Box?" I was wondering... Could it be a new Linux/ARM target device board, faster than a Raspberry Pi and better than a BeagleBone Black??? Why, yes! Yes, it was a Linux/ARM target device board, faster than anything around! It was a Freescale i.MX6 Sabre Smart Device Board (SDB)! Cool... Quad Core ARM Cortex A9 1GHz with 1GB of RAM. So, cool... I installed the Freescale One Box OpenWRT Linux image onto its SD card and booted it up into Linux. But, wait! One thing was missing... What was it? What could be missing? Why, it had no Java SE Embedded installed on it yet, of course! So, I went to the JDK 7u45 download link. Clicked on "Accept License Agreement", and clicked on "jdk-7u45-linux-arm-vfp-sflt.tar.gz", installed the bad boy, and all was good. Java SE Embedded 7u45 on a Freescale One Box. Nice... Hinkmond

• Will you share your SQL Server configuration?

  - by Bill Graziano

  I regularly visit client sites and review their SQL Server configurations.  I come across all kinds of strange settings.  I’ve been thinking about a way to aggregate people’s configurations and see what’s common and what’s unique.  I used to do that with polls on SQLTeam.com.  I think we can find out more interesting things if we look at combinations of settings in relation to size and volume. I’ve been working on an application for another project that is similar.  It will be fairly easy to use that code for this.  I can have something up and running in a few days – if people are interested in it.  I admit that I often come up with ideas that just don’t make sense.  This may be one of them.  One of your biggest concerns has be how secure your data is.  My solution is not to store anything identifying.  The instance name and database names can both be “anonymized” and I don’t store the machine name or IP address or anything to do with logins. Some of the questions I’m curious about are: At what size database does the Enterprise Edition become prevalent? Given the total size of the databases how much RAM is common? How many people have multiple data files?  At what size does that become prevalent? How common is database mirroring?  Replication?  Log shipping? How common is full recovery mode?  At what data size does it become prevalent? I think those are all questions that are easy to answer -- with the right data.  The big question is whether or not people will share their SQL Server configurations.  I understand that organizations in regulated or high security environments can’t participate.  But I think that leaves many, many people that can.  Are you willing to share your configuration and learn about others?  I have a simple sign up form here.  It’s actually a mailing list signup that also captures your edition, number of servers and largest database.  The list will only be used for this project.  Is your SQL Server is configured correctly?  Do you wonder what the next step is as your data grows?  Take a second and sign up.

• Friday Stats

  - by jjg

  As some of you may have noticed, we've recently opened a new repository in the Code Tools project for small utilities which can be used to gather info about the OpenJDK code base and builds. 1 The latest addition is a utility for analyzing the class file versions in a collection of class files. I've posted an example set of results from analyzing the class files in an OpenJDK build on Linux. 2. Most of the files are version 52 files as you would expect, but there is a surprising number of version 51 and 50 files, as well as a handful of v45.3 files as well. Digging deeper, it turns out that Nashorn is still using version 51 class files, and the Serviceability Agent is still using version 50 class files and one 45.3 class file, leaving the remainder of the 45.3 class files coming from RMI. For more info on the different class file versions, see Joe Darcy's class file version decoder rIng. Thanks to Stuart Marks for planting the seed for the class file version tool. See the project page, repo, and mail archive. http://cr.openjdk.java.net/~jjg/cfv-summary/open/

• Java EE 6 and Maven 3 using CLI

  - by arungupta

  NetBeans and Eclipse provide tools, templates, wizards and code generators for building a Java EE 6 application. They both also allow a Java EE 6 Maven project to be created. In his recent screencast, Adam Bien explained how a Java EE 6 project can be easily created at command-line using Maven 3. The screencast walks through the process of creating the project using command-line. The created project has no dependency on NetBeans and GlassFish but can still be opened in NetBeans and deployed on GlassFish. A complete list of Adam's screencasts are available here. Tons of similar videos are also available on GlassFishVideos channel.

• Non-blocking I/O using Servlet 3.1: Scalable applications using Java EE 7 (TOTD #188)

  - by arungupta

  Servlet 3.0 allowed asynchronous request processing but only traditional I/O was permitted. This can restrict scalability of your applications. In a typical application, ServletInputStream is read in a while loop. public class TestServlet extends HttpServlet {    protected void doGet(HttpServletRequest request, HttpServletResponse response)         throws IOException, ServletException {     ServletInputStream input = request.getInputStream();       byte[] b = new byte[1024];       int len = -1;       while ((len = input.read(b)) != -1) {          . . .        }   }} If the incoming data is blocking or streamed slower than the server can read then the server thread is waiting for that data. The same can happen if the data is written to ServletOutputStream. This is resolved in Servet 3.1 (JSR 340, to be released as part Java EE 7) by adding event listeners - ReadListener and WriteListener interfaces. These are then registered using ServletInputStream.setReadListener and ServletOutputStream.setWriteListener. The listeners have callback methods that are invoked when the content is available to be read or can be written without blocking. The updated doGet in our case will look like: AsyncContext context = request.startAsync();ServletInputStream input = request.getInputStream();input.setReadListener(new MyReadListener(input, context)); Invoking setXXXListener methods indicate that non-blocking I/O is used instead of the traditional I/O. At most one ReadListener can be registered on ServletIntputStream and similarly at most one WriteListener can be registered on ServletOutputStream. ServletInputStream.isReady and ServletInputStream.isFinished are new methods to check the status of non-blocking I/O read. ServletOutputStream.canWrite is a new method to check if data can be written without blocking.  MyReadListener implementation looks like: @Overridepublic void onDataAvailable() { try { StringBuilder sb = new StringBuilder(); int len = -1; byte b[] = new byte[1024]; while (input.isReady() && (len = input.read(b)) != -1) { String data = new String(b, 0, len); System.out.println("--> " + data); } } catch (IOException ex) { Logger.getLogger(MyReadListener.class.getName()).log(Level.SEVERE, null, ex); }}@Overridepublic void onAllDataRead() { System.out.println("onAllDataRead"); context.complete();}@Overridepublic void onError(Throwable t) { t.printStackTrace(); context.complete();} This implementation has three callbacks: onDataAvailable callback method is called whenever data can be read without blocking onAllDataRead callback method is invoked data for the current request is completely read. onError callback is invoked if there is an error processing the request. Notice, context.complete() is called in onAllDataRead and onError to signal the completion of data read. For now, the first chunk of available data need to be read in the doGet or service method of the Servlet. Rest of the data can be read in a non-blocking way using ReadListener after that. This is going to get cleaned up where all data read can happen in ReadListener only. The sample explained above can be downloaded from here and works with GlassFish 4.0 build 64 and onwards. The slides and a complete re-run of What's new in Servlet 3.1: An Overview session at JavaOne is available here. Here are some more references for you: Java EE 7 Specification Status Servlet Specification Project JSR Expert Group Discussion Archive Servlet 3.1 Javadocs

• SQL Saturday 43 (Redmond, WA) Review

  - by BuckWoody

  Last Saturday (June 12th) we held a “SQL Saturday” (more about those here) event in Redmond, Washington. The event was held at the Microsoft campus, at the Mixer in our new location called the “Commons”. This is a mall-like area that we have on campus, and the Mixer is a large building with lots of meeting rooms, so it made a perfect location for the event. There was a sign to find the parking, and once there they had a sign to show how to get to the building. Since it’s a secure facility, Greg Larsen and crew had a person manning the door so that even late arrivals could get in. We had about 400 sign up for the event, and a little over 300 attend (official numbers later). I think we would have had a lot more, but the sun was out – and you just can’t underestimate the effect of that here in the Pacific Northwest. We joke a lot about not seeing the sun much, but when a day like what we had on Saturday comes around, and on a weekend at that, you’d cancel your wedding to go outside to play in the sun. And your spouse would agree with you for doing it. We had some top-notch speakers, including Clifford Dibble and Kalen Delany. The food was great, we had multiple sponsors (including Confio who seems to be at all of these) and the attendees were from all over the professional spectrum, from developers to BI to DBA’s. Everyone I saw was very engaged, and when I visited room-to-room I saw almost no one in the halls – everyone was in the sessions. I also saw a much larger Microsoft presence this year, especially from Dan Jones’ team. I had a great turnout at my session, and yes, I was wearing an Oracle staff shirt. I did that because I wanted to show that the session I gave on “SQL Server for the Oracle DBA” was non-marketing – I couldn’t exactly bash Oracle wearing their colors! These events are amazing. I can’t emphasize enough how much I appreciate the volunteers and how much work they put into these events, and to you for coming. If you’re reading this and you haven’t attended one yet, definitely find out if there is one in your area – and if not, start one. It’s a lot of work, but it’s totally worth it.       Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Finding which activities will execute next in a process instance

  - by Mark Nelson

    We have had a few queries lately about how to find out what activity (or activities) will be the next to execute in a particular process instance.  It is possible to do this, however you will need to use a couple of undocumented APIs.  That means that they could (and probably will) change in some future release and break your code.  If you understand the risks of using undocumented APIs and are prepared to accept that risk, read on… READ MORE >>

• SOA Composite Sensors : Good Practice

  - by angelo.santagata

  I was discussing a interesting design problem with a colleague of mine Niall (his blog) on the topic of how to cancel an inflight SOA Composite process.  Obviously one way to do this is to cancel the process from enterprise Manager ( http://hostort/em ) , however we were thinking this isnt a “user friendly” way of doing this.. If you look at Nialls blog you’ll see he’s highlighted a number of different APIs which enable you the ability to manipulate the SCA instance, e.g. Code Snippet to purge (delete) an instance How to determine the instanceId from a composite_sensor_value using the “composite_sensor_value” table How to determine a BPEL Process status using the cube_instance table   Now all of these require that you know the instanceId of your SOA Composite, how does one find this out? Well the easiest way of doing this is to create a composite sensor on the SCA component. A composite sensor is simply a way of publishing a piece of business data as part of your composite. The magic here is that you can later query composites based on this value. So a good best practice is that for any composites you create consider publishing a composite sensor value using a primary key of some sort , e.g. orderId, that way if you need to manipulate/query composites you can easily look up the instanceId using the sensorid.   For information on how to create a composite Sensor id see this documentation link

• Need to Determine the Engine Status?

  - by user702295

  If you need to establish the status of the engine, begin with this SQL: select status, engine, engine_version,fore_column_name from dm.forecast_history The status of an engine run is stored in the FORECAST_HISTORY table, in the “status” field.  We can also find in that table the FORE_COLUMN_NAME field. This field includes the name of the column in SALES_DATA in which the relevant forecast is stored. Here are the possible statuses: -1, -2 : The engine failed in the initialization phase.  Which means, before the engine manager created the engines.  0 : The engine stopped in the optimization phase.  Which means, after the engines were created.  1: The engine finished the run successfully.  2: Forecast was never calculated for the relevant column that is mentioned in FORE_COLUMN_NAME.

• Architects, Leadership, and Influence

  - by Bob Rhubart

  Technical expertise is a given for architects. In addition to solid development experience, extensive knowledge of technical trends, tools, standards, and methodolgies (not to mention business accumen) provides the foundation for the decisions the architect must make in the effort to get all the pieces to work together. But even superior technical chops can't overcome a lack of leadership. Leadership is about influence: the ability to effectively communicate — to sell your ideas and defend your decisions in a manner that affects the decisions of the people around you. Leadership and influence are especially important in situations in which the architect may not have the authority to simply tell people what to do. And even when the architect has that kind of authority, influential leadership can mean the difference between gaining real buy-in and support from colleagues and stakeholders, and settling for their grudging acceptance (or worse). Guess which outcome is likely to produce the best results. In a previous post I presented some examples of the kind of criticism that is leveled at architects, a great deal of which can be attributed to a lack of leadership and influence on the part of the targets of that criticism. So it was serendipitous that I recently ran across a post on the Harvard Business Review blog written by Chris Musselwhite and Tammie Plouffe. That post, When Your Influence Is Ineffective, includes this: [I]nfluence becomes ineffective when individuals become so focused on the desired outcome that they fail to fully consider the situation. While the influencer may still gain the short-term desired outcome, he or she can do long-term damage to personal effectiveness and the organization, as it creates an atmosphere of distrust where people stop listening, and the potential for innovation or progress is diminished. The need to "see the big picture" is a grossly reductive assesement of the architect's responsibilities — but that doesn't mean it's not true. That big picture perspective must encompass both the technological elements of the architecture and the elements responsible for implementing those technologies in compliance with the prescribed architecture. Technologies may be tempermental, but they don't have personalities or egos, and they are unlikely to carry a grudge — not yet, anyway (Hello, Skynet!).  Effective leadership and the ability to influence people can help to ensure that all the pieces fit and that they work together, today and tomorrow.

• usage of setPropertyListener and setActionListener

  - by Vijay Mohan

  The incorrect usage could lead to hard-to-debug problems so better to understand the fundamentals behind it's working.setpropertyListener queues an event on the server side, so if for a command component you have a showPopup behavior/actionListner as well as setPropertyListener then fwk does the queuing correctly and raises further event on the component. While, the setactionListener simply raises an event on the server side instead of queueing it, so any further event on command component gets cancelled.Also, if you use an ActionListener and showPopup behavior together on a command component, then the order of their invocation is undetermined and also one of event gets cancelled on the component. So, either use only actionListner and do the popup invocation stuff progrmmatically in your bean or use the declarative stuff logically so that no clash of event happens.

• New Sample Demonstrating the Traversing of Tree Bindings

  A technique that I seem to use a fair amount, particularly in the construction of dynamic UIs is the use of a ADF Tree Binding to encode a multi-level master-detail relationship which is then expressed in the UI in some kind of looping form – usually a series of nested af:iterators, rather than the conventional tree or treetable. This technique exploits two features of the treebinding. First the fact that an treebinding can return both a collectionModel as well as a treeModel, this collectionModel can be used directly by an iterator. Secondly that the “rows” returned by the collectionModel themselves contain an attribute called .children. This attribute in turn gives access to a collection of all the children of that node which can also be iterated over. Putting this together you can represent the data encoded into a tree binding in all sorts of ways. As an example I’ve put together a very simple sample based on the HT schema and uploaded it to the ADF Sample project. It produces this UI: The important code is shown here for a Region -> Country -> Location Hierachy: <af:iterator id="i1" value="#{bindings.AllRegions.collectionModel}" var="rgn"> <af:showDetailHeader text="#{rgn.RegionName}" disclosed="true" id="sdh1"> <af:iterator id="i2" value="#{rgn.children}" var="cnty">     <af:showDetailHeader text="#{cnty.CountryName}" disclosed="true" id="sdh2">       <af:iterator id="i3" value="#{cnty.children}" var="loc">         <af:panelList id="pl1">         <af:outputText value="#{loc.City}" id="ot3"/>           </af:panelList>         </af:iterator>       </af:showDetailHeader>     </af:iterator>   </af:showDetailHeader> </af:iterator>  You can download the entire sample from here:
