  • What is meant by 4 GL?

    - by Geek
    I came across the term 4GL(generation language) in reading about Oracle ADF Busniess components . I want to know what exactly is 4GL ? This is the actual quote from the book Oracle Fusion Guide: Oracle ADF Business Components is the business services layer of choice in Oracle Fusion application development. Compared to other persistence layers, ADF Business Components provides exceptional built-in business application functionality and maximally declarative experience that makes it a perfect match for those who seek an end-to-end fourth generation language (4GL) Java EE development architecture.

    I just downloaded oh-my-zsh and found out that 'd' has been taken over by some command I do not know.

  • JavaOne 2013: (Key) Notes of a conference – State of the Java platform and all the roadmaps by Amis

    - by JuergenKress
    Last week’s JavaOne conference provided insights in the roadmap of the Java platform as well as in the current state of things in the Java community. The close relationship between Oracle and IBM concerning Java, the (continuing) lack of such a relationship with Google, the support from Microsoft for Java applications on its Azure cloud and the vibrant developer community – with over 200 different Java User Groups in many countries of the world. There were no major surprises or stunning announcements. Java EE 7 (release in June) was celebrated, the progress of Java 8 SE explained as well as the progress on Java Embedded and ME. The availability of NetBeans 7.4 RC1 and JDK 8 Early Adopters release as well as the open sourcing of project Avatar probably were the only real news stories. The convergence of JavaFX and Java SE is almost complete; the upcoming alignment of Java SE Embedded and Java ME is the next big consolidation step that will lead to a unified platform where developers can use the same skills, development tools and APIs on EE, SE, SE Embedded and ME development. This means that anything that runs on ME will run on SE (Embedded) and EE – not necessarily the reverse because not all SE APIs are part of the compact profile or the ME environment. However, the trimming down of the SE libraries and the increased capabilities of devices mean that a pretty rich JVM runs on many devices – such as JavaFX 8 on the Raspberry PI. The major theme of the conference was Internet of Things. A world of things that are smart and connected, devices like sensors, cameras and equipment from cars, fridges and television sets to printers, security gates and kiosks that all run Java and are all capable of sending data over local network connections or directly over the internet. The number of devices that has these capabilities is rapidly growing. This means that the number of places where Java programs can help program the behavior of devices is growing too. It also means that the volume of data generated is expanding and that we have to find ways to harvest that data, possibly do a local pre-processing (filter, aggregate) and channel the data to back end systems. Terms typically used are edge devices (small, simple, publishing data), gateways (receiving data from many devices, collecting and consolidating, pre-processing, sending onwards to back end – typically using real time event processing) and enterprise services – receiving the data-turned-information from the gateways to further consolidate, distribute and act upon. A cheap device like the Raspberry PI is a perfect way to get started as a Java developer with what embedded (device) programming means and how interaction with physical input and output takes place. Roadmaps The over all progress on Java is visualized in this overview: Read the full article here.

  • OSB unit testing, part 1 by Qualogy

    - by JuergenKress
    First you need to implement the simple bpel process like this : In my current project, I inherited a lot of OSB components that have been developed by (former) team members, but they all lack unit tests. This is a situation I really dislike, since this makes it much harder to refactor or bug-fix the existing code base. So, for all newly created components (and components I have to bug-fix) I strive to add unit tests. Of course, the unit tests will be created using my favourite testing tool: soapUI ! Unit of test The unit test should be created for the service composition, which in OSB terms should be the proxy service combination with its business service. Now, since you do not want to rely on any other services, you should provide mock services for all services invoked from your Component-Under-Test. In a previous article, I wrote about mocking your services in soapUI. While this approach would also be valid here, creating a mock service (and certainly deploying it on a separate WebServer) does violate one of the core principles of unit testing: to make your unit tests as self-contained as possible, i.e. not depending on any external components. In this article, I will show you how to achieve this by simply providing a mock response inside your unit test. Scenario The scenario I implement for testing is a simple currency converter; the external request consists of a from and a to currency, and an amount (in currency from). The service will perform an exchange rate lookup using the WebServiceX CurrencyConverter and return a response to the caller consisting of both the source and target currencies and amounts. For the purpose of unit testing, I will implement a mock response for the exchange rate lookup. Read the complete article here.

  • How can I use a .html file as desktop background/wallpaper?

    - by dudealfred
    I have one of those underpowered netbooks with Lubuntu. I also have an iPod Touch. I'd like the best of both worlds. So I would like to create an active html wallpaper with beautiful little squared icons to launch my webapps through Chromium/Firefox. I've read a bit, but it looks like there isn't really anything that would allow for that. Why? Does anyone have any other alternatives (apart from buying an iPad)? :)

  • GUI won't load, but the desktop background loads. Can't access the terminal

    - by Mickeysofine
    Having trouble with the Ubuntu GUI. I can log in just fine (see this)... everything looks normal there. But as soon as I put in my password, I get this. I tried a few different troubleshooting keyboard commands (ctrl+alt+t, crtl+alt+delete), and only the latter worked. I can interact with that window just fine, except I am unable to resize or move it. The first time I logged in, I got a dialog box that said, "Ubuntu has experienced an internal error. Send error report?" Doesn't say anything now. Yes I tried restarting it. Thanks a bunch, Michael EDIT: Trying to start a guest session leads to the same problem.

    Hardware: HP Pavilion DV7 notebook: 8GB DDR3, 2x 750GB SATA2 HDD, I7 c+ Radeon GPU, eSATA, Bluray, etc. Currently multiboot with Win7-64 + choice of 5 'buntu-64. Prefer Xubuntu-64-alternate, but not able to install software RAID-0 at the last active partition on both HDDs. Tried many types: real boot partition, etc. All my Linux op sys boot successfully from the extended partitions on both drives, but without RAID of any kind. Theory - yes. But has anyone really succeeded with 12.04 software RAID-0?

  • Extremely slow desktop and laggy. Need help with graphics driver

    - by user171624
    I am a fresh newbie Ubuntu user and I just installed my first Ubuntu 13.04 onto my HP Slate 2. I did a liveCD on my USB drive and installed everything perfectly fine...nice and smooth, not a trace of lag. Then I rebooted using Ubuntu itself on the computer, it was extremely slow and laggy. Icons or any buttons doesn't trigger right away, the performance of the entire thing looks like either 0.25 fps to 1 fps. My HP Slate 2 information: Processor: Intel Atom Z670 1.5Ghz Memory Ram: 2.0 GB Videocard: Intel GMA 600 (PowerVr SGX535) SolidStateDrive(SSD): 32GB I tried installing the intel linux graphics driver and it failed to install because it said I don't have any intel based graphics card. Well...I do as you see above. What can I do? I can't get on the internet on it, I'm using my primary computer (Windows 7) to do all the searchings and put the files onto the USB to move it over to my tablet. Simply...I don't get it...using liveCD on USB, it was all nice and smooth...then after the installation...BOOM! Slow, laggy, and etc. Can anyone help me? Thanks!

  • How can I configure desktop notification display time in Google Chrome?

    - by netvope
    Recently Gmail introduced an HTML5-based desktop notification feature for Google Chrome users (see this). It's very useful, however, the notifications disappear too quickly (in about 5 seconds) and I couldn't find a way to change the display time. Ideally, I would like the notification to stay for a few minutes if there is no user activity (or about 15 seconds if there is user activity). Is that possible?

  • How to start cross-platform desktop game development? [closed]

    - by Wamer
    I am interested in developing some 2d game since I have graduated and got some time to spare. I am looking for some advices where to start and with what. My main target platforms are Mac and Windows (later porting/rewriting/modifying for iOS, Android or WP7 is considerable). I need some advices about language I should choose, frameworks, engines and this kind of stuff. I gotta start somehow, but first of all I need to know how. Choosing good language with great framework/engine is key to ongoing successful game development I think.

  • System.Runtime.InteropServices.COMException (0x80070008): Not enough storage is available to process

    - by Darryl Braaten
    I am trying to diagnose this exception. "System.Runtime.InteropServices.COMException (0x80070008): Not enough storage is available to process this command. (Exception from HRESULT: 0x80070008) at System.Runtime.Remoting.RemotingServices.AllocateUninitializedObject(RuntimeType objectType) at System.Runtime.Remoting.RemotingServices.AllocateUninitializedObject(Type objectType) at System.Runtime.Remoting.Activation.ActivationServices.CreateInstance(Type serverType) at System.Runtime.Remoting.Activation.ActivationServices.IsCurrentContextOK(Type serverType, Object[] props, Boolean bNewObj) at Oracle.DataAccess.Client.CThreadPool..ctor() at Oracle.DataAccess.Client.OracleCommand.set_CommandTimeout(Int32 value) ... It does not look like any of the normal types of "storage" have hit any limits. The application is using about 400MB of memory, 70 threads, 2000 handles and the hard drive has many GB free. The machine is running Windows 2003 Enterprise server with 16GB of RAM so memory shouldn't be an issue. The application is running as a windows service so there are no GDI objects being used. Running out of GDI handles is a common cause of this exception. Database connections, commands & readers are all all wrapped with using blocks so they should be getting cleaned up correctly.

  • How to reclaim storage for deleted LOBs

    - by Jim Hudson
    I have a LOB tablespace. Currently holding 9GB out of 12GB available. And, as far as I can tell, deleting records doesn't reclaim any storage in the tablespace. I'm getting worried about handling further processing. This is Oracle 11.1 and the data are in a CLOB and a BLOB column in the same table. The LOB Index segments (SYS_IL...) are small, all the storage is in the data segments (SYS_LOB...) We'e tried purge and coalesce and didn't get anywhere -- same number of bytes in user_extents. "Alter table xxx move" will work, but we'd need to have someplace to move it to that has enough space for the revised data. We'd also need to do that off hours and rebuild the indexes, of course, but that's easy enough. Copying out the good data and doing a truncate, then copying it back, will also work. But that's pretty much just what the "alter table" command does. Am I missing some easy ways to shrink things down and get the storage back? Or is "alter table xxx move" the best approach? Or is this a non-issue and Oracle will grab back the space from the deleted lob rows when it needs it?

  • Why is OracleDataAdapter.Fill() Very Slow?

    - by John Gietzen
    I am using a pretty complex query to retrieve some data out of one of our billing databases. I'm running in to an issue where the query seems to complete fairly quickly when executed with SQL Developer, but does not seem to ever finish when using the OracleDataAdapter.Fill() method. I'm only trying to read about 1000 rows, and the query completes in SQL Developer in about 20 seconds. What could be causing such drastic differences in performance? I have tons of other queries that run quickly using the same function. Here is the code I'm using to execute the query: using Oracle.DataAccess.Client; ... public DataTable ExecuteExternalQuery(string connectionString, string providerName, string queryText) { DbConnection connection = null; DbCommand selectCommand = null; DbDataAdapter adapter = null; switch (providerName) { case "System.Data.OracleClient": case "Oracle.DataAccess.Client": connection = new OracleConnection(connectionString); selectCommand = connection.CreateCommand(); adapter = new OracleDataAdapter((OracleCommand)selectCommand); break; ... } DataTable table = null; try { connection.Open(); selectCommand.CommandText = queryText; selectCommand.CommandTimeout = 300000; selectCommand.CommandType = CommandType.Text; table = new DataTable("result"); table.Locale = CultureInfo.CurrentCulture; adapter.Fill(table); } finally { adapter.Dispose(); if (connection.State != ConnectionState.Closed) { connection.Close(); } } return table; } And here is the general outline of the SQL I'm using: with trouble_calls as ( select work_order_number, account_number, date_entered from work_orders where date_entered >= sysdate - (15 + 31) -- Use the index to limit the number of rows scanned and wo_status not in ('Cancelled') and wo_type = 'Trouble Call' ) select account_number, work_order_number, date_entered from trouble_calls wo where wo.icoms_date >= sysdate - 15 and ( select count(*) from trouble_calls repeat where wo.account_number = repeat.account_number and wo.work_order_number <> repeat.work_order_number and wo.date_entered - repeat.date_entered between 0 and 30 ) >= 1
