  Newer versions of oracle have implemented a great new technology to help solve problems, called "error messages."  Unfortunately, I can't find any reference to an error message named 'is no longer able to connect.

  And why you are moving your site from inventory?  When you have installed oracle, he put the inventory where he wanted.  There is no reason to try to change or replace.

• connection to the oracle application express using java and jdbc

  Hello!

  I am trying to build a java application using jbcd to connect to my Oracle Application Express DB but unable to connect actually using the following syntax:

  Private final static String DB = "myworkspacename";

  Private final static String RUTA public = "@apex.oracle.com:1521";

  private public static final String URL = "jdbc: Slim:" + RUTA + "/" + DB;

  private static final String DRIVER = "oracle.jdbc.OracleDriver";

  a USER private final static string = " " [email protected] "; "

  private final static String PASS = "MonMotpasse";

  and then I start the connection via:

  CONEX = DriverManager.getConnection(URL,USER,PASS);

  but finally I get the following error:

  IO error: the network adapter could not establish the connection

  any ideas on what goes wrong will be appreciated...

  Simple answer... YOU can't connect externally to the hosted instance of Oracle with a jdbc connection or sql developer/Toad.  Not allowed...

  If you need this capability, I would suggest downloading of Oracle 11 g XE and building you own database...

• problem connecting to the oracle database.

  A user cannot connect to the Oracle server. What will be the problem and the solution to the problem?

  When you post here you must give us: error codes, logs, DB versions, SO it's 32-bit is 64-bit?

  Give us more details about your problem and maybe I can help you.

• Connect to the Oracle database - does not connect

  I am new to JAVA and for the first time that I am trying to connect to an Oracle using JAVA data. Well, I get an error when you try to connect to the database. I can see that the error doesn't that make strings passed to make the databases of connection are NULL. Thus, an error (see error below).
  
  Question
  How is the 'connection' varriable is NULL?
  It seems that the hold 'try' session was not executed. This session is broken?

  The try section runs very well but only partially because you get the exception "ClassNotFoundException", which means that it is impossible to load the Oracle driver class (so it does not reach the line where it says):

  Class.forName(driverName);
  

  You intercept this exception and then simply print a line "could not find the database connection: null". Then you let the code continue, obviously without you still initialize your variables.

  I would recommend rewriting those catch blocks throw new RuntimeException so that the code will not continue any further when an error is detected in the try or don't catch not all of them if you donot want to manage them appropriately.

  As for your problem, you probably have not added the ojdbc14.jar is to your project, and this is why it cannot find the class OracleDriver.

  Finally, try adding {noformat}

  {noformat} around your code when you post code.  It makes it a lot more readable.

• Do not drop DMSYS user on Oracle 11 upgrade.

  Hello;
  
  
  Version Oracle 11.2.0.2
  OS version Red Hat 5 AS U7
  
  I missed fall DMSYS user on a database and now I display the invalid objects for DMSYS. I dropped DMSYS casacde, but things always show.
  
  I searched MOS documents but have not found a cleaning paper.
  
  Can someone point me to the right direction?
  
  Not having not problem, just want to clean.

  There is a step by step procedure here: http://docs.oracle.com/cd/E11882_01/datamine.112/e16807/upgrade_odm.htm

  After droping DMSYS user with the cascade option make sure you:

  SQL> DELETE FROM sys.exppkgact$ WHERE schema = 'DMSYS';
  SQL> SELECT COUNT(*) FROM dba_synonyms WHERE table_owner = 'DMSYS';
  

  If the result of the select is not zero lines, create and run a SQL script as follows:

  SQL> set head off
  SQL> spool directory_path/drop_dmsys_synonyms.sql
  SQL> SELECT 'Drop public synonym ' ||'"'||SYNONYM_NAME||'";'
               FROM DBA_SYNONYMS WHERE TABLE_OWNER = 'DMSYS';
  SQL> spool off
  SQL> @directory_path/drop_dmsys_synonyms.sql
  

• The idea to send a message to all connected users.

  Dears,
  
  I am developing through oracle forms an idea of sending a message pop up to all connected users.
  Example, I need to inform users to quit smoking in 5 minutes due to a restart of the application server.
  
  I thought about a timer trigger that will check every 5 seconds or 10 seconds one value in a table somewhere. But I don't want to use the timer associated with forms of oracle triggers.
  
  Y at - it an idea?
  
  Please let me know.
  
  Joe

  Normally, there is a clue when the Java Bean needs a greater than 1.3 JRE, so I guess (but it must be confirmed by a real test) that she will be executed with the JInitiator.

• DB connection - user SYS with wrong password

  Hi all
  
  One strange thing I noticed with the SYS user as Oracle 9i (who has never worked on earlier versions), it is that I can connect to SYS as SYSDBA with wrong password user as well! Please guide how to avoid this...
  (I have looked for a solution online but could not find any :())

  There is nothing wrong, and nothing should be, IMO, prevented.
  When you connect to the server as a user in the Group dba (Unix) or group ora_dba (Windows), you are an advanced user and authentication of the o/s applies to you, and you don't need a password .
  Login as the owner of the software (oracle) all the time, what do many DBA, is a bad idea in any case, you can remove anyufile o/s level.

  Strategies to avoid it:
  -Make sure that your account is not in the groups I mentioned
  or
  -disable authentication of the o/s of editiing sqlnet.ora

  The two procedures are documented.

  Finally, note someone who has root access can move easily.

• Invalid connection for the Oracle 10 g Server

  Hello
  
  I installed Oracle 10 g server on my pc.
  
  I checked the Option to use the same user name and password for all accounts and used the password as an administrator
  
  But when I try to connect as sysdba or sysopera with admin as password it's displaying as connection not valid.
  
  Please tell me how I can connect to the Oracle database

  User for login names are SYS or SYSTEM. Try to connect as administrator system or admin/sys as sysdba.

  Which tool you use to connect? dbconsole, sqlplus? You should be able to connect with the authentication of the OS "/ as sysdba".

• How to authenticate the user using oracle user

  Hello
  I do some piece of my apex application login authentication and what I want to do is to let people connect with the user Oracle (schema) and the password also, in the system. I know that we have a dba.users table that contains the usernames and respective encrypted passwords for users of Oracle. But using this table is not the right way for my solution. Is there another way I can authenticate the user if he uses the username/password Oracle (as sys/respective password)?

  Hello:

  You might want to consider 'DAD authentication' for your application as described here
