• Oacle SQL Developer Java Version issue

  Installed Oracle SQL Developer 3.2.09.30 (liberation, 27 August 2012) on SUSE Linux 11 r2. Also installed JDK 1.7.0_07.
  
  When it is running: sqldeveloper.sh sh-> pop-up window:
  
  You try to run with Java 1.7.0_07
  
  This product running is supported with a minimum of Java
  version 1.6.0_04 and a maximum version lower than 1.7.
  
  This product is not supported and may not work correctly
  If you continue. Continue anyway?
  
  -That means that my best bet is to use the Java JDK 1.6.0_04 version?
  
  I read a few bugs online complain under the Oracle SQL Developer java 1.7. But those who are back in 2011. I wonder if the problem has since been resolved.
  
  -Also, do I need to run the SQL Developer as user oracle?
  
  Thank you

• I could develop Java Application for Blackberry device software version 5.0 to 6.0 JDE

  Hi, expert,

  I saw this line of the ' BlackBerry Java Development Environment - 4.7.0 - fundamentals Guide'.

  It is said:

  ===============================

  With each major version of the BlackBerry Device Software and the FMV of BlackBerry, Research In Motion includes the
  corresponding Java API and version of the BlackBerry® Java® development environment. The version of the BlackBerry device
  Software determines the version of the BlackBerry® integrated development environment that you can use to develop
  applications. For example, RIM released BlackBerry Device Software version 4.0 and BlackBerry JDE version 4.0 in even
  time. BlackBerry JDE version 4.0 supports APIs that were introduced in BlackBerry Device Software version 4.0
  and BlackBerry JVM version 4.0.

  The applications that you create by using BlackBerry JDE Version 4.0 only work on BlackBerry devices
  running BlackBerry Device Software version 4.0 or later.

  =========================

  The last sentence talking about version 4.0 of JDE. I think that would mean that I could not develop a java application on JDE 6.0 for Blackberry 5.0 version of the software, even if I do not use any new API to 6.0. However, it seems to me that it is a useless limitation. Could someone throw some lights on it?

  I'm going to agree with superdirt here.

  I have the 5.0 OS update of applications work well on OS 5.0, 6.0 and 7.0 of the OS OS phones.  I try not to recompile for levels of the OS, if I can, and so far I've been perfectly safe with OS 5.0 running on the later levels of the operating system.  So you should be able to get away with just using OS 5.0.

  Not that it is important for you, but I just thought I documents some historical information about level changes.  .

  As far as I know it 2 change cod in the file format, one to the 4.0 OS and the other in OS 4.2.  Therefore, if you want to run anything in OS 6.0 or above, it must be compiled in OS 4.2 or higher.  Again, I have applications compiled to OS 4.2 running on OS 6.0, without no problem devices.

  There have been changes to the API - the result is that the code that works in OS xx does not work in OS yy where yy is after xx.  I hit a few of them and have so far managed to rework the code so that it works very well on both levels of the operating system.  In general it is things that I do wrong anyway, as the older operating systems (from memory) are not as strict on when the event Thread must be used.

  The problem with OS 4.7 compatibility is an impact and to get more of this, for devices touch screen only, I compile using OS 4.7.  If an application that uses only the functionality that was available in the OS 4.2, I compile on OS 4.2 for non touch screen phones and OS 4.7 for touchscreen phones.  And everything works fine.

  I hope this helps.

• Extension of SQL Developer Java does not

  Hello

  I developed a small extension of Java to start the SQL Developer via command line and put some parameters such as the server name, user and password to create a connection when you start.

  THS connection will be deleted when closing.

  This extension was working fine until the 3.0.2 version and does not work with version 4.0.2.

  My question: are there changes in the load of an extension?

  Any help would be appreciated, thanks.

  
  

  I developed a small extension of Java to start the SQL Developer via command line and put some parameters such as the server name, user and password to create a connection when you start.

  THS connection will be deleted when closing.

  This extension was working fine until the 3.0.2 version and does not work with version 4.0.2.

  My question: are there changes in the load of an extension?

  Yes - there are MAJOR changes and they include the use of "lazy" loading of extensions.

  See note on the main page of Oracle extension exchange.

  http://www.Oracle.com/technetwork/developer-tools/SQL-Developer/Extensions-083825.html Special Note regarding Extensions developed prior to SQL

  Developer v4.0:

  With the new version of SQL Developer 4.0, an extension that was written for an earlier version of the SQL Developer will no longer work. Developer SQL is based on the JDeveloper Framework. We have updated the framework to be up-to-date with the JDeveloper 12 c version. With JDeveloper 11 g 2, they switched to an OSGI framework. The JDeveloper team issued instructions to update your extensions to be compatible with the new framework and SQL v4.0 developer.

  Note that first sentence than the previous expansions 'won't work' If you use them in 4.x

  It also appears to be bugs or incompatibilities between the extension of JDeveloper published SDK and the "new" version Sql Dev 4.x uses. The public is 12.1.2, and is one that is available for download for use in the development of an extension. SQL Dev uses version 12.1.3 and who has NOT yet been published.

  I have a new thread posted recently to ask about any aspect of this compatibility, but have not yet had all the answers:

  https://community.Oracle.com/thread/3570408

  A few simple extensions, perhaps yours, may only need a small change in the file "extension.xml" use appropriate brackets.

  Other extensions will require additional changes. One of the main changes is the new ESDK of "lazy" loading of extensions use.

  Some additional info is available on the Java.net site:

• Java Web development vs development

  Hello, I have an MDS Runtime application that calls some web services.  The SDM Runtime will not work on new BlackBerry devices I need to re - write the application.  My client has especially World Edition, curve, Tour and storm.  I'm leaning toward the approach of Web development, so I can stay with the IDE of Visual Studio I know, but I have to go the route of development Java?  Thanks in advance for stakeholders.

  I can't say I'm a Java expert (yet), but I came also the route of the MDS Runtime.  Personally, I started web and then moved to the runtime and now primarily Java but I don't think that there is only one solution fits all approach.  Web is generally faster and easier to build and is certainly makes sense in many situations, but Java is more functional.  With that said, most of our projects requires Java due to the need for storage capacity / persistent data as good integration with the native BB applications offline.  New versions of devices/OS provide much better browsers and features, but our Organization still has too many older devices to make it a factor.  BlackBerry widget technology is also established and upcoming but the runtime being dropped so quickly gave me a little wary to jump on that train, until it matures a bit.

  My advice is to build your app for the web offers all the features necessary for your application, but on the same ramp time up your skills, so that you can produce a Java solution when the time comes, it will be.

  Good luck!

• Oracle database: "Developer" or "DBA".. ??

  Hello..
  
  I am of the India & new to Oracle databases (currently a final year student, engineering).
  
  I want to know about 'Gurus' (just a noble gesture, not the terminology is used here) here, what track/stream should I choose with regard to obtaining "Oracle certified" in databases with a pattern of increasing my credentials as a freshness, i.e., get better roles job & pay (short-term as well long term in mind). (DBA or developer side)
  
  The reason I ask that (a probably stupid question, for some) is because someone in my college (which I assume to be knowing at least more than I do) told me that as a fresh developer track is preferable because a DBA role can be granted to someone who is new (whether certified or not). But my interest is more towards being a DBA*.
  
  So, please guide me to go for which the track-> Forms Developer /(PL/SQL), 10 g / 11 g s/n or both (in the order please..) _
  
  (I can look stupid for some but if please try and stay with me;) I'm just a noob and this is my 1st post here).
  
  Thank you (* in advance)...

  Srini is good for the long term, your knowledge is good for the short term. In general, there is way to jobs of developer and experience will help you if you see dba, that's what you think it is in the real world. Given that usually 10 x more development than dba the necessary work, pure dba work tends to be limited to department stores. Small shops don't appreciate all s/n, but having the jurisdiction in addition to being a developer makes you valuable.

  But always keep your eyes open for special situations.

• The daily tasks such as production Oracle DBA & developer DBA

  Hi all DBA,.
  
  I'm curious to know what you do every day as production Oracle DBA or developer DBA. More than a year ago, I became a DBA and before that, I was PL/SQL Developer. I navigate in the Administrator's guide and, now, in the middle of the Oracle database concepts. Then I intend to read backup and restore. As my day job: I check the backup log file. Check db objects and make sure that all are valid and check free space on each tablespace and adding data files if necessary. Also monitor top sqls session or above through OEM and tried tune sqls top of the page. Meet the demands of users, such 'kill a suspended session' and synchronize the data of a table between databases and refresh QA production db app. sometimes the air in the alerts log too if we have problems. Some people suggested TKPROF each file in short why trace the trace file generated. Don't you think that it is really beneficial? What should I do to improve the skills and abilities as an Oracle DBA. Really appreciate your ideas.

• 'Performance' is missing for the node after activate it "View > DBA.

  Version 4.0.1.14

  Build HAND-14, 48

  Open the DBA ' View > DBA ', expand the connection of interest, you try expand the node of the 'Performance '. But the 'Performance' node is missing.

  Someone knows why? This option should be available in this version.

  Thank you
  Eugen

  Hi Eugen,

  Node of the view of the DBA Performance developed for me against a 11.2.0.1 4.0.1 database with just the Pack Tuning license check box selected.  This could be one of those situations where...

  1. the database to which you are connecting is a version prior to 10 g R1, when Tuning Pack became available.

  2. you may hit a bug caused by not using is not a recent version of Java JDK 7, for example jdk1.7.0_51 or higher.

  3. your preferences of user for the 4.0.1 has been corrupted somehow.

  So if (1) is not the reason, check and upgrade the JDK if necessary, then consider creating newly migrated, or the new default, user settings.   Just...

  1. exit SQL Developer, delete/rename system4.0.1.14.48, restart SQL Developer (possibly without the migration of user settings).

  2 download and install the 4.0.2 patch now available.  Start SQL Developer (possibly without the migration of user settings).

  Hope this helps,

• Why Firefox always tell me that it blocks Java Deployment Toolkit after that I did the update?

  On the page Web 'Mozilla - check your Plugins', I was told that the 'Java Deployment Toolkit' was vulnerable. So I did the update. But then, I got the same problem still. Why? And should I care?

  Please see the attached screenshot.

  The most funny thing is... I visited two sites that use Java, being Java.com, but I haven't seen the black banner of the blocking message.

  The Java Deployment Toolkit can be the most recent version, but Oracle has not yet fixed the vulnerabilities with this plugin; so Mozilla still there on the red list and point require the user to use "Request enable" to deactivate it. A 'soft-block' - can be used if needed, but needs user by implementing action.

  More specifically, do you have a program on your PC that is really needed as Deployment Toolkit?
  Or is your concern that simply that it is disabled after update of Java?

  Very few applications consumer even uses this Deployment Toolkit, aimed at people who develop Java applications or applications such as the various Oracle programs in the workplace.

  Back to before Oracle acquired Sun Java systems in 2010, this Deployment Toolkit has not been installed with the runtime environment Java for users. Java developers needed to install a separate developers Toolbox for this Plugin - had the SDK program.
