  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

  Extract the files in a directory of your choice. The extracted files are the installation of Oracle files. You will use the installer from this directory.

  (1) make a FULL install 11 g on the existing (but defective!) version 10 g?

  Is not ideal. You are much better to get rid of (uninstall) 10 g.

  (2) uninstall (ugh!) the existing 10g version and THEN install the full version of 11g?

  Yes, certainly. This version is not yet compatible with your version of Windows. After you have installed has the potential to cause problems.

  No. 10g of uninstall, restart with 11g

• Oracle Forms 11g - ORA-12154: TNS error

  Well, until I post my info, I searched and searched all over Google, OTN, Experts-Exchange, etc... to try and figure this one out and I am puzzled. So here goes. I get the dreaded ' * ORA-12154: TNS: could not resolve the connect identifier specified * "error. This is my environment:
  
  ----------------------------------------------------------------------------------------------
  Server: Red Hat Enterprise Linux 5 version performs the following:
  Oracle Database 11g (Rel 1): 11.2.0.10
  Oracle Fusion Middleware 11g (rel. 11.1.1.2.0) Forms Server
  
  I can connect via SQL + no problem
  ----------------------------------------------------------------------------------------------
  Client: My Windows XP Professional PC.
  
  I can't TNSPING the SID of the database, no problem.
  I can connect via SQL + no problem
  I can connect via TOAD to the db without problem
  I can connect to Oracle Enterprise Manager through the web interface, no problem
  
  I have 2 houses Oracle (Oracle 8.0.6, Oracle 11.1.0.1) on my PC. The current House is currently the 11g one. I have my background on my PC Setup very well.
  
  The problem is when I try to run an example of form through the web, I created, the login prompt appears and I get my name in username/password / database SID and it is, I get the error. Of the clues as to what I should look for? Ultimately it is an application that all users will access and they should not have to worry about anything whatsoever to have installed on their PC.
  
  Thank you

  Keep in mind that file tnsnames.ora forms 11g is under $ORACLE_INSTANCE/config

  I tried to connect with SQL and TOAD, but the same error.
  
  Can anyone tell me the reason.

  The reason is probably that your client software is too old (and supported in the previous Millennium).

• Deletion of Oracle DB properties to solve the problem?

  HI Craig & team

  I've isolated the problem to my problem to the derived properties (2), causing the app to crash.  I have reproduced the issue in my TEST environment.  I was able to go back in a delete the properties before I loaded the Version (what would trigger the problem) However, I am unable to start the RDP application to go and delete.

  Can I remove property categories in the Oracle DB?

  Thank you!

  Removing a property is not a good option, can you try the following to properties that have caused problems for you and then try to restart the services (this is also not recommended, just a temporary solution, I'd wait to hear other members)

  Update rm_property_param set x_value = "where i_property_id IN (select i_property_id in the rm_property_definition where C_Abbrev = 'XXX' AND E_PROP_TYPE = 'Derived');

  commit;

  Note: Don't forget to check the dependency, if these properties are mentioned in other parameters of calculation of property, you may find yourself messing everything, works if they are autonomous.

• Oracle.DataAccess 32 bit and x 64 with a build? There is no corresponding version?

  We used Oracle.DataAccess to generate a .net assembly. version has been 10.1.0.400. I can't seem to find the x 64 native install for this 10.1.0.400 version we are running IIS in 64-bit mode. so I need an x 64 native bit Assembly.
  
  We deploy our .net assembly for a 32-bit and x 64 bit machines. so I need to install a version of Oracle.DataAccess with the same 32-bit and x 64 bit version.
  
  I can't find a version in common 32-bit and x 64 bit.
  
  It seems that the closer, I can get is 2.102.3.2 for x 64 and 2.102.2.20
  
  I have no problem re-construction of the Assembly, and as long as I can get the same fix on both 32 bit and x 64 bit version in the GAC, it should work very well. help, where can I find a corresponding 32-bit and x 64 bit version to install?

  Hello

  Yes, you must have a support account in order to login to metalink and get the fixes.

  Part of the ODP.NET installation includes installation of policy files in the GAC which redirect use the latest version installed, so I think you should be fine compilation on 10.2.0.2.21 x 86 (for example) and the distribution to the 10.2.0.3.02 x 64. You must compile a version<= the="" version="" you="" want="" to="" be="" able="" to="" run="" it="" on="">

• Oracle generates invalid WSDL

  Hi, guys!
  I use XML DB native Web Services of the project.
  The type of input parameters for my duties are "Object Types".
  But when I have an attribute in one object type to another object, the wsdl document which generates the Oracle is not valid.
  
  CREATE or REPLACE TYPE name_tp AS OBJECT)
  first name varchar2 (20).
  ......)
  
  CREATE or REPLACE TYPE person_tp AS OBJECT)
  name_tp person_name,
  .......)
  
  create or replace function test (p_person person_tp)
  ......
  
  When I have this situation, the wsdl file is not valid, because Oracle generates sth like this
  < xsd: element name = "person_name" type = "name_tp" / >
  Instead of
  < xsd: element name = "person_name" type = "tns:name_tp" / >
  
  How can any ideas, I solve this problem?
  
  Which is profound,
  Slavi

  The problem with the type being is not in the correct namespace is bug 8274288. You need to upgrade to 11.2.0.1.0 or contact support and ask for a single patch for this bug.

  no idea why I get this error and how to get rid of?

  Thank you

  HI EmAr,

  This is my answer to another question:

  Houston 30003: java.lang.ClassCastException: weblogic.jdbc.wrapper.PoolConnection_weblogic_jdbc_sqlserverbase_ddai cannot be cast to oracle.jdbc.OracleConnection b

  We have seen this error, when we use one database other than Oracle. When error occurs, disconnect the session and try to connect again.

  We had to create root application module (by calling Configuration.createRootApplicationModule) when connecting (and release after use). I thought what happens because of AOS pooling, it tries to use invalidated (last session) AM. (this is just guessing).

  Now, we have no problem with other databases (mysql, postgresql, oracle).

  Earlier, I found these links. In my view, it has solved the problem basically... (I didn't try it)

  Configuration of SQLBuilder - Dreamix blog

  Oracle ADF business with several databases components

  After answering this question, I have tried the links, he solved the problem completely...

  You create a servlet context listener which affects jbo.sqlbuilder system config and put this context listener in the Web.XML (as mentioned in the links)

  Kind regards
  Sara.

• error in a WPF application using oracle.manageddataaccess.client

  Hello

  We have problems with a WPF MVVM using Oracle.ManagedDataAccess.Client application. We installed oracle.manageddataaccess.dll release 12.1.0.1.0 on a developer machine with 64 bit of Windows 7, Microsoft Visual Studio 2013 and Microsoft .NET Framework 4 OS. Installation seems to be ok and oracle.manageddataaccess.dll results to be registered in .net\assembly\GAC_MSIL c:\windows\microsoft. But when we try to compile the application, the following errors occurs

  Error 175: The ADO.NET provider with invariant name 'Oracle.ManagedDataAccess.Client' not is either not saved in the config machine or the application of the file, or could not be loaded

  errors are caused by the entity data model files (there is an error for each .edmx file).

  Note that the application works on another computer with the same configuration, so I guess that the problem is due to a bad setting on the computer

  any idea?

  Hello

  Finally, we have solved the problem! simply, we uninstalled and reinstalled Visual Studio and Oracle.manageddataaccess in this order. Now it's working. Thank you
