Error to connect oracle 10g client and designer BO 4.0

hello,
I try to connect oracle 10g client and designer BO 4.0.
I created an ODBC connection to function in the administration tools of data sources but I can not connect once in designer.
I tried using the driver directly oracle designer 10 but I have the same error that is this:
DBD: ORA-12154: TNS: connection identifier specified could not be resolved
someone there had the same concerns?
cordially

Hi,
so it looks like that your TNSNAMES.ORA file isn`t properly configured. Thats why you can connect with the IDT to your Oracle Database.
Your DBA`s should sent you the correct TNSNAMES.ORA file or the entry for your DB prior. After the tnsping works, you will be able to use the IDT properly.

Connecting oracle 10g express edition to jdeveloper

I am having all kinds of problems connecting oracle 10g express edition with my jdeveloper 10.1.3.3. I can query the database from my command line so I know it is set up, but for whatever reason jdeveloper will not connect with it. When I try to connect with the database through jdeveloper here is the error I keep getting:
Listener refused the connection with the following error:
ORA-12518, TNS:listener could not hand off client connection
The Connection descriptor used by the client was:
localhost:1521:ORCL
I have been all through the google results looking for an answer and have come to the conclusion that it is something with either the listerner file or the tns file, but as of yet have been unable to locate them. here are both of those files too.

Please any help would be appreciated I have been at this for days, thanks.

This has to be some kind of bug with 10g express because I see lots of people having similar problems. I'm in the process of uninstalling 10g, and I will re-install it see if that makes a difference. Again if anyone has any other ideas please keep them coming because this is utter BS it shouldn't be this hard.

How to connect Oracle 10g from OBIEE on Linux?

- OBIEE 10.1.3.4.0 is running on Cent 5 Linux M1 (*64* bit). My Oracle database is running another similar machine M2.
- I installed oracle 64 bit client on M1 but could not connect to run the report, connection issue. Even nqcmd didn't helped.
- I guess it was because OBIEE is *32* bit application and hence need 32 bit client.
- I tried installing Oracle 32 bit Linux client on M1 but installation fails with some dependency (Not sure if we can install 32 bit client on 64 bit machine)
Q1 - Any suggestion at this point?
Q2 - Is there any way we could connect OBIEE to Oracle via ODBC drivers. I could not found any odbc driver/so file when I wan installed 64 bit client. Any suggestion for this?
Thanks in Advance!

The computer running XE server does not need a client installed.
If you are trying to connect from another computer, install the XE client and create file C:\XEClient\NETWORK\ADMIN\TNSNAMES.ORA with the following contents (replace ip_address as appropriate):
XE =
    (DESCRIPTION =
       (ADDRESS_LIST =
          (ADDRESS = (PROTOCOL = TCP)(HOST = ip_address)(PORT = 1521))
       (CONNECT_DATA =
          (SERVICE_NAME = XE)
{code}Test with
{code:java}
sqlplus SYSTEM/password@XE

please excuse, but I have no answer.
My only hint to you is, copy the question to one of the rdbms-, or odbc-forums of the otn. Here is the forms-forum, where the guys normally didn't need an odbc connection to different databases.

But i am not able to connect my oracle 10g express edition database. It throws error ORA-12154 : TNS could not resolve service name.( same error displayed while trying to connect from SQL Plus).But from toad i am able to access the database. May be because here I am able to select the proper home.
Here i am adding my tns entry

can any one suggest what the actual problem is?
Thanks ..........

Hello,
Oracle 10g XE is rather specific and, I'm not sure that you can upgrade it to 10.2.0.4 .
However, Oracle published an Upgrade Guide for Oracle Express Edition but, it's limited to *10.2.0.3*:
http://download.oracle.com/docs/cd/B25329_01/doc/server.102/b32391/toc.htm
But be careful:
Once you have upgraded to Oracle Database 10g, you cannot downgrade back to Oracle Database Express Edition.Hope this help.
Best regards,

Unable to connect Oracle 10g Express from Visual Studio Server Explorer

Hello,
Please help me out here. I am connecting from Visual Studio 2008 to Oracle 10g Express Edition and the I have installed the ODAC 11 and the ODP.NET as well for Visual Studio(Both include Oracle Developer tools). But whenever I tried to connect from my Visual Studio 2008 server explorer so that I can have the database and its object there, I do get this error : "ORA-12560 : TNS: protocol adapter error."
The following is what I specified in my connection box:
DataSource Name: (Local Database)
Username : HR
Password: the password for it.
My OS is : Windows Vista Ultimate.
Please anyone who has solved such error should just help out here.
Thanks all

Thank you for your reply. I will like to know if you can use Visual Studio. In visual studio there is what we called Server Explorer and from there you can create connection and access all the database server from there. I am able to connect to the Oracle XE through the browser and I was able to crete table and other stuffs like that but when I tried to connect from Visual Studio 2008, I get the 12560 Error. I checked my TNSNAMES and found this:
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = OLAMMIE)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
Look at what I have in my Sqlnet.Ora file,
# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file wont exist and without the native
# authentication, they will not be able to connect to the database on NT.
SQLNET.AUTHENTICATION_SERVICES = (NTS)
Please kindly help me out of this as it is very urgent. I can connect from browser using http://127.0.0.1:8080/apex but cannot connect from my C# code and Server Explorer. What is likely to cause this error.
Thank you for helping me in advance.

Connect Oracle 10g and OWB to SQL Server 2005 in Windows XP

I am unable to create a working connection between Oracle 10g and a SQL Server database. I have followed the instructions in several sources, but when I attempt to connect to the MSSQL database through SQL Plus or SQL Developer, I get the ORA-03135 error. I set up a non-Oracle location in OWB and the connection test was successful but the metadata would not import. Creating an Oracle location with the same parameters produced the ORA-03135 error.
In TNSNAMES.ORA I placed the following definition:
MSSQL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = wgilt1.hsd1.nj.comcast.net)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = MSSQL)
(HS = OK)
In LISTENER.ORA I placed the following in the SID_LIST_LISTENER:
(SID_DESC =
(SID_NAME = MSSQL)
(ORACLE_HOME = C:\oracle\product\10.2.0\db_2)
(PROGRAM = hsodbc)
The inimssql.ora file contains the following:
HS_FDS_CONNECT_INFO = MSSQL
HS_DB_NAME = MSSQL
HS_FDS_TRACE_LEVEL = ON
HS_FDS_TRACE_FILE_NAME = c:\hs_fds_mssql.log
What is missing?

could be a copy paste issue, but please make sure the tnsnames.ora has at least on space in from of each line after the alias.
In addition what is the listener status? Please post the output of lsnrctl status <listener name>.
Need to know also the output of: C:\oracle\product\10.2.0\db_2\bin\hsodbc

Can't connect to X11 window server using :0.0 as the value of DISPLAY variable.you apparently set the display correctly (:0:0) if you are installing locally.
