• How to solve the problem of Oracle SQL Developer Connection?

  People,
  
  Hello. I use the Oracle 11 GR 1 material database. The database https://localhost.localdomain:1158 control console / em works correctly. I can create a database and a table with success.
  
  My OS is Linux and connects to the internet successfully.

  Connection name: DB1 (is my database name)
  User name: SYS (this is the user name I used to connect to the Console)
  Password: SYS (this is the password used to connect to the Console)
  Connection type: basic
  Host name: localhost
  Port: 1158
  SID: DB1 (it is created during the installation of the database)
  
  But the error message: "status: failed - IO exception Connection Reset."

  user name: sys
  password: enter_your_correct_password given at the time of the installation of oracle

  role: select sysdba if you would connect as sysdba otherwise select normal for users other than the sys

  HostName: Enter your ip or hostname of the oracle example server address:-192.168.11.12

  to find the terminal/command prompt open hostname in oracle installed machine
  type---> hostname

  type ping hostname--->

  You can find the IP address of the server

  Port number: 1521 (default)---> I guess, otherwise check the port number in the file tnsnames.ora under your ORACLE_HOME/network/admin folder

  SID: DB1

  try it
  Good luck

• Problems with Oracle sql developer

  Hello
  
  I have problems with my Oracle SQL developer 3.0.04 Version. It makes windows unstable once the query tries to display too many rows of data (for example, 300 k). Is there a way to solve this problem in addition to increasing the amount of physical memory? I currently have only 1 GB of RAM on this machine. Thank you.

  Hello

  Upgrading hardware can be a very satisfying experience, especially as it is almost always little expensive compared to the value of your time. Virtual memory / paging on the Windows and PC hardware is a huge disappointment, so more memory on Windows is a cure-all. With more and more common 64-bit operating systems, laptop computers and the PC is currently available with 8G of memory.

  That said, I think few users have a business case for the visualization of the hundreds of thousands of lines via a graphical user interface.

  Getting back to what concerns the management of memory in java, I want to put in a plug for the garbage and first new Garbage Collector. It will be the production in JDK 1.7, but can be found in the JDK 1.6 u14 & high in experimental option. The most recent revision update, the better it is. Just add something like this in your sqldeveloper.conf file:

  AddVMOption - XX: + UnlockExperimentalVMOptions
  AddVMOption - XX: + UseG1GC
  AddVMOption - XX: + G1YoungGenSize = 25 m
  AddVMOption - XX: + G1ParallelRSetUpdatingEnabled
  AddVMOption - XX: + G1ParallelRSetScanningEnabled

  It does a much better job of actually release unused memory in the context of the o/s.

• Difference between Oracle Designer and developer of forms

  Hello
  
  Could someone explain to me the subject
  
  
  Rgds
  
  sexy

  Oracle Designer is a complete computer-aided design tool and software development. It gives you a set of tools for logical design as an entity-relationship diagrammer, a Process Modeler and a stream Diagrammer. It has a set of design tools from database to physical database design. It can also help to design modules of Oracle Forms application, reports Oracle, PL/SQL Web Toolkit or Visual Basic (VB6, I think, but versions not later as VB.Net). It will then generate these modules. It stores your designs in a metadata repository in an Oracle database, and you can make some nice reports your design data.

  Oracle Forms Developer does one thing and does it very well - it allows you to design and develop modules of Oracle Forms. Note that Designer can do this too, but because the designer generates your forms, you don't have quite as much control over the way they look and work like you would with the Oracle Forms Developer.

  One last thing, these tools are considered to be "mature". For Designer, this means that not much has changed or improved for a while. Forms, however, is still a few changes and improvements with each new version. Nothing really important, but more designer. See the statement of management tools for more information.

• Problem connecting to Oracle SQL Developer

  Hi all
  
  I am trying to connect to the database from the remote computer through Oracle SQL Developer, it gives me the following error.
  
  Status: Faliure-Test failed: connection/o: the network adapter could not establish the connection.
  
  I had given the host name as the name assigned to this server, it did not work.
  
  Later, I tried with the IP address of the server, it worked.
  
  Can someone tell me how I can connect by giving the hostname instead of IP address.
  
  Thanks in advance,
  Vinay

  Hi Vinay,

  One way would be to add an entry in your hosts file. On windoze, you can find it in

• SEVERE: Exception initialization 'oracle.dbtools.crest.fcp.DataModelerAddin' extension ' Oracle SQL Developer Data Modeling

  After some testing today with a new installation and plugin subversion in the latest edition of data Modeler this error happens with every start of the tool.

  Have removed and unzipped the installation once again without changing the error.

  After that, I started with another user on my computer, it the error does not occur.

  Is there a system folder to remove the configuration of my personal like jdeveloper and sql developer?

  I lose the most important features, for example. have no browser and cannot open a design.

  Hi Torsten,

  Thanks for reporting the problem. I logged a bug.

  You can view together as "list of system types" directory to "preference > Data Modeler"-probably no longer exists. I guess that the setting for this directory is empty when you start SQL Dev as a different user.

  This error doesn't seem to appear in SDDM 4.0.3.

  Is there a regression? Or can I change something in the designer to avoid this error?

  Thanks for your help.

  Best regards

  Cédric

  Hi Cedric,

  Thanks for reporting this.  I connected a bug on this issue.

  It seems that this problem occurs whenever a view references another view.

  If the 4.0.3 version works for you, you probably better to stick with that until this problem is resolved.

• Import all the objects from Oracle Designer to SDDM 4.1.1

  Hello

  I installed SDDM 4.1.1.888 and you import from designer 10.1

  I'm looking to import all the Designer items at a time.

  Steps to follow:

  1 / import from Oracle Designer model

  2 / select connection

  3 / Select Global shared activities

  4 / Select an Application (in my case: SIS)

  If I import only the points of view, import works fine. If I import just the Tables, import works fine.

  However, if I import the Tables and views I seem to lose the most sous-vues. If I import views and Tables, the sequence numbers are not transferred and a half subviews are missing. I can't win.

  Any help would be appreciated.

  Thank you

  Jenny

  Hi Jenny,

  If I can import successfully with the old version, shouldn't I be able with the newest one?

  As David said, you have a problem with the key foreign and probably views involved in the definition of the FK. DM 4.0.3 is not supported for FKs views. 4.1 DM has this support and try to import definitions from the repository of the designer.

  So, if you can import with DM 4.0.3 and you are satisfied with the result then import with 4.0.3 and start using DM 4.1.

• Oracle SQL Developer/Oracle 11 g/Windows 7 - cannot connect 'sys as sysdba'

  Hello
  
  I downloaded and installed SQL Developer 3.2.20.09, the latest version, separately from Oracle 11 g, because the version provided with Oracle 11 g did not work properly.
  
  Now, I'm trying to connect SQL Developer 3.2 to my instance of 11g Oracle installed on Windows 7.
  
  I can log in with the user name SYS AS SYSDBA using SQLPLUS, text bundled with Oracle 11g, with a password to null and without any problem.
  
  However, when I try to connect to the same instance using the graphical tool based on Java, Oracle SQL Developer 3.2 I get this error:
  
  Status: Failure-Test failed: ORA-01031: insufficient privileges
  
  I already checked the computer management and I am already a member of administrators and 'ORA_DBA' groups.
  I already checked tnsnames.ora, etc. and everything is indicated as it should.
  I also checked my SID and it corresponds to what was named during the installation of Oracle 11 g.
  
  Is someone can you please tell me why I can't connect using SYS AS SYSDBA?

• Installation of Oracle SQL Developer and Java

  I finished installing the Oracle Client without problems. SQL Developer opened for the first time and he asks me the full path Java.exe.
  
  That's fine, but when I entered the java.exe I just don't ask again, no errors. Repeat to infinity.
  
  I have the most recent Java SDK installed and tried the 32-bit and 64-bit versions (jdk 7u4). I even tried to install Oracle Client version 11.1.0 AND 11.2.0 to see if that makes a difference, but it is all the same.
  
  I uploaded a screenshot if that helps: http://i50.tinypic.com/mjtqte.jpg
  
  Any ideas?
  
  Kind regards

  Hi Gunnar.

  Documentation:
  http://docs.Oracle.com/CD/E25259_01/doc.31/e26419/install.htm#sthref8

  Ideas:

  -Do not use java7
  -Use JDK JRE not
  -On widows, there is a version of SQLDeveloper, including jdk 6 java
  -Instant client is not necessary - but if you want to use use at least 11.2.0.2
  -SetJavaHome updated to sqldeveloper\sqldeveloper\bin\sqldeveloper.conf to point to the JDK
  -There is some confusion about 32-bit and 64-bit operating systems, java and SQLDeveloper, you can search the forum for more details, for example: put on the title: "Unable to start Oracle SQL Developer.

• I changed the name of the computer, now I can not connect to Oracle SQL Developer

  Hello my friends!
  
  Everything worked perfectly until I needed to change the name of the computer and now I can no longer connect in Oracle SQL Developer 3.1.
  I restarted Oracle 11 g by stopping and restarting. The order message said stop and start successfully. This tells me Oracle 11 g Express is running, but I can no longer
  connect to Oracle SQL Developer 3.1.
  
  How can I fix?
  
  Thank you all!

  J man,

  I'm not a pro at Oracle XE, but I would say that this is not a problem of SQL * Developer, but the listener of OracleXE.
  Now, I'm in total guessing game mode:
  find the "listener.ora" file in your Oracle installation (from [url http://docs.oracle.com/cd/E17781_01/server.112/e18804/network.htm#ADMQS168] this document is c:\oraclexe\app\oracle\product\11.2.0\server\NETWORK\ADMIN\listener.ora
  I'm sure that it is coded in the old hostname, simply replace it with the new host name.
  Restart your receiver and please try to connect again.

• Oracle BI developer Client tools without Tnsnames.ora

  Hello gurus,
  
  
  In my local computer of the user, I installed Oracle BI developer Client Tools version 11.1.1.6
  It allows us to open a repository online/offline without installing OBIEE and Oracle database in our user, just put in ODBC connection.
  But the problem is when the user want to try to create the new repository, it seems that "the connection failed".
  There we have to copy some tnsnames.ora? In our local computer of the user, there is no tnsnames.ora since it does not install OBIEE/Oracle database on the local computer.
  
  Help, please
  
  
  Thanks in advance
  
  See you soon,.

  Hey Joe,
  If you import data from an oracle database. You must install the Oracle database client. Then only, you can import data from Oracle database.
  In addition, you are supposed to copy file ora, TNSNAMES.

• Oracle SQL Developer environment encoding

  I have Oracle SQL Developer (3.1.07) and I'm working with a database using WE8ISO8859P1 coding (SELECT * FROM nls_database_parameters setting WHERE = "NLS_CHARACTERSET" ;))
  
  I have problems with the registration of batches that contains unicode symbols. When I open previously saved the package that all unicode symbols are turned to "".
  
  Should what settings I change to keep the SQL Developer these symbols?
  I tried to put environment encoding to "ISO-8859-15" and some other encodings, but it won't help. ".
  
  Published by: 919845 on 2012.9.3 04:44

  Short version (if I find time, I'll do better writing upwards).

  Your understanding so far is false. If you read carefully, the table [1] is supposed to contain the "games of Unicode characters... as long as some older character sets»

  The only current, recommended Oracle db name for Unicode character set is: AL32UTF8. (Read globalization support guide for application of unicode support, etc.)

  Only Iso character sets I know media letter lowercase n cedilla, U + 0146 are 8859-13 (Latin-7) and 8859-10 (Latin-6) (and perhaps 8859-4/Latin-4). 8859-1 and 8859-15 defines that character.
  Table A-4 lists the Oracle names for character sets of database that matches the 8859-x character sets for example:
  http://docs.Oracle.com/CD/E11882_01/server.112/e10729/applocaledata.htm#i635047

  So, whatever it is, it seems that you need to change your database character set.
