• Question RE: being an Oracle Developer, best practices.

  Dear Oracle gurus:
  
  If you would be so kind as to entertain a few lame need questions will Jr. Oracle Developer, I would be very happy!
  
  1. If I understand correctly, I can pretty much Learn SQL and PL/SQL using Oracle 10 g Express without the need to install further configuration of Oracle? SQL Developer and Oracle 10 g Express would be sufficient for learning SQL and PL/SQL?
  
  2. how the future for an Oracle developer who is well versed in SQL and PL/SQL? Was hoping to specialize in this aspect of Oracle and may continue with the discoverer (I had previously had some experience deploy reports in Discoverer 3/3i). Your opinions?
  
  3. as an Oracle Developer, am I supposed to know that s/n matter as well? Or stick to the development? The reason why I ask is - I found that if I try to do too much, a whole bunch of nothing does happen. Isn't better to focus on something and do it well?
  
  4. any ideas or comments about the future of development in Oracle you want to share?
  
  Thank you for your time! :)

  Oracle 10g Express Edition will give you at least 1 year of learning. If you are really able to SQL and PL/SQL Express, you are longer than many so-called Oracle professionals.

  2. how the future for an Oracle developer who is well versed in SQL and PL/SQL? Was hoping to specialize in this aspect of Oracle and may continue with the discoverer (I had previously had some experience deploy reports in Discoverer 3/3i). Your opinions?

  Unfortunately, I see that SQL and PL/SQL to be lost in the hype Java and .net. More and more developers and applications forget the basics of database.

  Indeed, a much touted merger devleopment demo focuses strongly on tanks (single general-purpose attribute-value lookup Table)

  A good developer knows his tool. A good database developer Oracle SQL doesn't understand.

  A great developer Oracle includes the internal implications of the database, but also a DBA. Both (but rarely) should work closely together.

  For example, a great developer understands that you do not commit in a loop. The 'why' of it is often seen by developers as "something DBA.

  I would say a lot of reading is in front of you. I would encourage the following, in the following order:

  Manual chapter, Oracle Concepts 1
  Guide the developer Oracle - foundations, chapters 1 & 2
  one of the books of database Oracle Expert Tom Kyte
  O'Reilly books "SQL Cookbook"
  Books O'Reilly Oracle PL/SQL (co-) written by Steve Feuerstein
  ORacle concepts, the rest
  Dan Morgan Library to http://www.morganslibrary.com
  Developer's Guide - Fundamentals - Oracle the rest
  The Oracle - other as interest falls Developer's Guide

  Oracle guides are available from http://tahiti.oracle.com and most SQL and PL/SQL can be exercised on the free and moderately light (sic) Express Edition.

• Choice of the development environment

  We are launching a major web application development project, and as usual, we are facing a question of choice of development environment.
  
  We have 2 options:
  
  1 MS Visual Studio 2005 ASP.Net, c# (.Net)
  2 flex and its components.
  
  Ours is a big data OLTP application; but looks are too important. dorsal is oracle and has approximately 200 paintings and we have about 15 tables of major transaction that contains on average 5 million documents.
  
  That, you people think is the right approach? If you need more information, please let me know.

  DAVO, my lead developer agrees with you on the argument that the FDS being expensive, is totally false.

  > Because it allows some radically cut development time and is indeed, as you say, cheaper than the other JMS solution.

  SDS has not scale is another false claim:

  > Because it's a bunch of servlets in a JAR that are running on a WebSphere or WebLogic application server and there are many other technologies based on servlets that serve millions of users every day. SDS scale.

• Is there real problems leaving the production as a 'full of APEX development environment?

  Hello

  We have recently installed APEX (5) in our production and Test environments.  We have not all applications running in Production at the moment.  Looking through the documentation I've learned that you can configure an instance of the APEX "APEX full development environment" or a "APEX Runtime Environment" and you can switch between the two through scripting.

  It is recommended to set your runtime production environment.  However when you do this you will lose access to admin functions.  My questions are:

  (1) if we look / account ADMIN secure as well as all users in our application workspace, is so no REAL question simply letting PROD as development environment?

  (2) If you make your Production environment, a runtime environment, it seems that you can import only new applications via the SQL script.  What happens when you export out of your Test instance and it has an application ID that is already used in the Production environment?  When you import forward, it lets create you a new application ID instead of using the existing one.  I fear that the admins will accidentally overwrite an existing application if they import via the script.

  You can keep the Apex Builder in production. Indeed, it gives you a lot of additional options.

  Ask the administrator to disable all accounts developer of workspace in the production environment, however.

  Also, export the applications run only, not run & Build. It gives a little extra coverage.

  When you import forward, it lets create you a new application ID instead of using the existing one.

  It would be bad practice. You would create a nightmare of versioning IMHO. What happens if you get an error of production application ID 1231, page 21, which is the application ID 132, page 21 in development? How can you know which application is which?

• Newbie question for the Oracle application server

  Hi Master,
  a DBA I am interesting to broaden my skill with learning on the application server.
  I knew that in the past before Weblogic bought by Oracle, Oracle, always using Oracle application server.
  Now with the Weblogic gaining more popularity on the market, which is the product the value of learning and get certified.
  
  Is it still useful to take Application Server 10 g or go with Weblogic. in certification path, Weblogic 10 g.
  WebLogic now replaces the Oracle application server, average abandoned Oracle Application Server?
  
  Please enlighten me and thank you for your help
  
  Lie

  Question if I go for Oracle WebLogic Server 10 g Administrator Certified Expert System it will be good to work with 11g thus?

  Make it part of the same system (now). Like WebLogic is the portal and the Jukebox, forms etc. are the records.

  What book other than the documentation that you have found the right one for learning.

  Yet to find one, Oracle documentation was OK.

  Is it better to learn the Linux or Windows version?

  Both are very well, choose the operating system you know better.

  Best regards

  mseberg

  I built my Middleware on Linux 64-bit test. Note that the 32-bit version allows to run Forms and Reports Developer.

  Beware of pre-installation tasks

  Install the Oracle database
  Linux RCU (repository creation utility)

  Database

  Use an existing database. (And it worked)

  My test was divided into four main parts: (in this order)

  Installation of the regional coordination unit
  WebLogic Server Install
  Install JRocket
  Forms and reports Install

  According to me, it took me two or three times to do things. (or at least work)

  I found myself with these URLs in the end:

  Administration Server Console http://Host/console 7001
  Enterprise Manager Console http://Host/em 7002
  Enterprise Manager Agent http://Host/emd/main
  Oracle Forms http://Host/formes/frmservlet 9001
  Oracle reports http://Host/rapports/rwservlet 9002

  So far, I have only an addition to my Web Page:

  http://www.Visi.com/~mseberg/compile_forms_on_wl.html

  As always this work orders:

  ./opmnctl status
  

  I was able to add PHP after you apply the hotfix 9292625.

• Can I use SqlPlus in Oracle11GR1 traditional development environment?

  Hello
  I downloaded Oracle 11 GR 1 material, but I want to write the sql code in the SqlPlus tradition environment which was in Oracle 9i or 8i (who had a history of white color). So how to get this here SqlPlus development environment? The current download and installation SqlDeveloper was installed and sqlplus command prompt has been provided. But I want to use this environment to sqlplus white screen. Please guide how to get that one.
  
  Thank you.

  First create a shortcut icon on your desktop to sqlplus.exe (in your oracle_home/bin directory).

  Then right-click on the icon and select Properties. Change these settings:

  Tab: General
     Put the instance name in the text box
  
  Tab: Shortcut
     Target: (your oracle_home)\bin\sqlplus.exe userid/password@databasename  --< use with caution
     Start in: (your oracle_home)\bin
     Run: Normal Window
     Change icon to whatever you want
  
  Tab: Options
     Cursor size: Small
     Command History, Buffer size: 50
                    , Number of buffers: 4
     Display options: Window
     Edit Options: check QuickEdit mode
                   check Insert mode
  
  Tab: Font
     Size: 8x12
     Font: Raster Fonts
  
  Tab: Layout
     (Screen Buffer Size is the 'virtual' size of the screen
      Window Size is what you see on the screen
      having a buffer size of 2000 allows sql plus to display
      very wide rows when sql plus LINESIZE is also 2000)
     Screen buffer size: Width: 2000
                         Height: 2000
     Window size: Width: 125
                  Height: 55
  
     check Let system position window
  
  Tab: Colors
     I like aqua on black, but whatever
  
  Tab: Compatibility
     Leave all these unchecked
  

  I like to include my user name and password in the determination of objectives, but this can be a security risk, so use with caution.

  And some of these parameters depend on the size of your monitor, your Visual acuity, etc so adjust to taste.

  Then, edit your glogin.sql file (it is in oracle_home/sqlplus/admin) and add these lines:

  SET serveroutput on
  SET linesize 2000
  SET pagesize 50000
  SET trimspool on
  SET long 50000
  SET tab off
  ALTER SESSION SET NLS_DATE_FORMAT = 'DD-MON-YYYY HH24:MI:SS';
  

  You can use any format you like for the date format, but make sure that it includes the portion of time.

  This is also where you put the PASS command to change the column you mentioned.
  Something like: COL some_column to 999999

  I also have this query in my glogin.sql:

  SELECT d.name, s.sid,s.serial#, p.spid
  FROM   v$process p
        ,v$session s
        ,v$database d
  WHERE  p.addr = s.paddr
  AND    s.audsid = userenv('SESSIONID');
  

  This info can be useful for some data dictionary queries (such as v$ session_longops).

  Then create a directory somewhere to organize all your scripts SQL more than of assistance. As c:\oraclescripts.

  Create a permanent environment variable called SQLPATH pointing to this directory.

  Every time that you run a script from the sqlplus prompt, it will search this directory if you do not have to call every time.

  Now, double-click the icon and try it.

• jDeveloper, this isn't a good IDE development environment

• Development environment for 10g R2

  Guys,
  I need to set up a development environment for the development of forms of oracle 10g r2. I am a new on oracle and because of the downsizing, we lost our DBAs so I'm on my own and need your huge support...
  
  Current settings: Oracle on the server: Oracle 10 g R2
  My local client installation: 10.1.0.4.2
  Suite Developer downloaded oracle of oracle: Oracle Forms: 10.1.2.0.2 (Developer suite 10.1.2.0.2)
  
  * Is it a decent development environment? or any incompatibility do you see that? *
  
  Second, I have heard different things on the development environment and would like to your comments as well:
  
  * Can I develop application forms in my own office, OC4j connecting my local machine (supplied with the suite) developer to run and develop forms? or what I need to put it on the server where oracle is installed? *
  
  * Fact to our oracle server needs any of application (weblogic) Server installed or simply OC4j can run on the server to run the production of forms? *
  
  
  Please help me to resolve my confusion so I can introduce the development environment for my management...
  
  Thank you very much...

  I just want to confirm one last thing... for purposes of development, I need not oracle application server to develop and test shapes on my local office OC4J and oracle connection is sufficient.

  Yes, developers just subsequently installed developer.

  But for testing (as I am the only developer) and the final production it has to work on oracle application server?

  The production, to use an Oracle application server (its also a matter of license). To be sure, confirm it by your Contact of Oracle.

  For the test, it depends... You have not necessary need to use an OAS, but if you do not, you do not test in "conditions of production.

• Should what development environment I use?

  Environment: 32-bit Windows 7, latest development environment Sun's Java, Visual Studio 8 most recent plugin beta BlackBerry 9700 Simulator works very well in the white list remote .NET/ASP/SQL Server 2008 to use as remote as possibly .asp page direct service calls, XMLHTTP and server applications.

  I would like some advice on what development product that I use.  I tried to use the version of Visual Studio Web plugin 2.0 beta 1.  Unfortunately I was having limited success and because I can't debug in this version of the plugin, I do a double page web/JavaScript on an ASP site debugging without any reference to blackberry.xxx until I am convinced then I copy the code in the index.htm or my BlackBerryActions.js and give it a try.  Unfortunately, without debug in version 2.0 beta 1 environment that I cannot use alert orders to see what is happening and the differences in behavior between the browser and the plug-in are important.  It's very painful, but I'm making slow progress.

  I also spent a day and 1/2 trying to download an Eclipse environment without success.  I tried several versions of the site referring to the documentation on the BB site and the various messages and I couldn't get the dependencies to the point where I could get the plug-in to install because of addiction.

  I feel that most of the applications that are built and are running and sold are applications in java environment makes full using Eclipse or the old environment.

  So I have three questions:

  (1) should I consider the Visual Studio Plugin 1.1 backup so that I can debug?  What do I lose?

  (2) I have can I just make the leap into the complete java development environment?

  (3) is there any web business success product plug-ins in the world of the app that I could look at to see what is possible.  My favorite so far is the Bloomberg application.  My impression is that it was built in the Java development environment.  This is the type of application, I'm only doing with more features.

  You use the tools for the construction of web pages or widgets?  If you create widgets, you will need version 2.0.

  The debugging support is coming for Web 2.0, plugin towards the end of this month (March)

• Two quick questions (hopefully) - right way to dynamically change the CSS class and put of Splash screen implemented

  Couple of quick questions have left me speechless!

  So, it seems obvious that many JavaFX applications want to dynamically change the CSS styles.  Is the best way to do it through la.getStyleClass () .add ("classname") < node >?  The underlying data structure is a list of observable.  So let's say we have 5 styles that simply to change the fill color of a circle of 5 different colors, respectively.  So if I have a condition in which I want to dynamically apply 1 of these 5 styles, as I do now it's by setting all 5 styles as a string in a list by using a static initializer, then I call < node > .getStyleClass () .removeAll (list), then getStyleClass () .add ("classname").  I do this to avoid adding again and still the same style and inflate the underlying list.  What is the right way to manage dynamic CSS styles?

  Finally a very simple I think.  So I know there's a little differently to implement a splash screen.  My app has certainly got bigger in the last few months of development and I noticed there are about a 5 second delay between when I run the application when I see the main stage.  I was thinking what a splash screen would be nice to fill that time.  I had no time to prototype using a Preloader and I fear that using another, early stage start-up again would be too long of a delay.  "I actually thought that using the Nice and simple JVM argument" - splash: image name > "would be simple, easy and effective.  Unfortunately when I try to do, the splash screen appears but never goes away.  Anyone know what is happening with this?

  Your mechanism to manage the css style classes is a good approach; I've used several times. I wonder why the style classes have been implemented as a list, instead of a game, but there may be cases of good use for the use of a list.

  In some cases you can also consider using CSS PsuedoClasses, which were presented in JavaFX 8. Here is a little easier to use, especially if you have two options. But a use case might look like:

  public class Message {
      public enum Status { NORMAL, WARNING, CRITICAL }
  
      private final ObjectProperty status = new SimpleObjectProperty<>(Status.NORMAL);
      private final StringProperty message = new SimpleStringProperty();
  
      // constructor, getters, setters, and property accessors....
  }
  

  public Label createLabel(Message message) {
      PseudoClass warning = PseudoClass.getPseudoClass("warning");
      PseudoClass critical = PseudoClass.getPseudoClass("critical");
  
      Label label = new Label();
      label.textProperty().bind(message.messageProperty());
      message.statusProperty().addListener((obs, oldStatus, newStatus) -> {
          label.pseudoClassStateChanged(warning, newStatus == Message.Status.WARNING);
          label.pseudoClassStateChanged(critical, newStatus == Message.Status.CRITICAL);
      }
      return label ;
  }
  

  And then your css looks like

  .label:warning {
      -fx-text-fill: orange ;
  }
  .label:critical {
      -fx-text-fill: red ;
  }

• Quick question on installing RUEI, RUEI 12 c Release 4 (12.1.0.5)

  
  Hi people,

  I have started the installation procedure, downloaded RUEI 12 c Release 4 (12.1.0.5).

  I had a quick question.

  I decided using the following installation option:

  Installation and configuration, journalist and collector of component on the same server (Red Hat
  Enterprise Linux 5)

  Use the distance journalist Oracle db, GR 11, 2 on a separate server (Suse 11, x 86-64)

  This configuration should work, the Oracle db running on Suse 11, but the RUEI
  components are run on RHEL 5?

  Thank you

  Hi Ashish, this should be no problem at all. In fact, it is a common facility.

• I have 2 quick questions on the Adobe Creative Cloud membership. I currently have 2 children in high school.  (1) is the license for 1 or can it covers 2 users? (2) can they access it from PC or MacBook this year? Thanks for your help.

  Adobe community, I have 2 quick questions on Adobe Creative Cloud membership. I am considering the Adobe Creative Cloud 'Plan of the student' for 2 children currently in high school.  (1) is the license for 1 or can it covers 2 users? (2) can they access it from PC or MacBook this year? Thanks for your help.

  each single-user license, it's just that, for a single user and can not (legally) be shared between two different users.

  programs of CC can be installed on pc or mac.  each user can install on an unlimited number of computers, but can only connect to, at most, two computers at a time.  These 2 computers can be 2 pcs, 2 macs, or one of each.

• I have a problem with debugging in a local development environment.

  I'm having a problem with my local development environment.

  I have version 10.3.5 WebLogic Server on my laptop and I am using Eclipse v3.8.1 as my IDE.

  I built a server in Eclipse, I imported a .war file and place the file properties to point to an Oracle database, not on my laptop.

  I built the project and added the server.

  But when I tried to start the server in debug mode I got this message. :

  Unable to connect to remote VM. Connection refused.     Connection refused: connect

  As the Weblogic Server is loaded on my laptop and I tried to run the server in the Eclipse Server view Debug

  Why it says "Failed to connect to remote virtual machine".

  Why he thinks I'm trying to debug remotely?

  I thought I was set up for local debugging:

  Hello

  To enable the debug option in Weblogic, please add the following lines (in bold print) to startWebLogic.cmd in bin directory - your domain

  Set JAVA_OPTIONS =-Xdebug - Xnoagent - Xrunjdwp: transport = dt_socket, address = 8453, server = y, suspend = n % SAVE_JAVA_OPTIONS %

  And in eclipse change port configuration debug as 8453.

  I hope this will work!

  Kind regards
