Help needed in connecting to oracle database in unity

Hi,
I have been trying to connect to Oracle database in my codes. I have tried using OdbcConnection and OleDbconnection. But both did not allowed me to connect to the database. The database, testDb, can be accessed using SQL plus as well as the SQL developer. I even tested the connection successful using ODBC data source administrator.
the following is my code for the connection string:
OdbcConnection connectionString = "Driver={Oracle ODBC Driver};Server=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP )(HOST=127.0.0.1)(PORT=1521))(CONNECT_DATA=(SID=Te stDb)));Uid=scott;Pwd=password;";
the error i got is [ODBC Driver Manager] Data Source name not found and no default driver specified.
for the driver parameter, i have tried using "Microsoft ODBC for Oracle". It gives me another error stating that the oracle and network components are not installed.
I even tried "Oracle in OraDb11g_home1" which was specified in the ODBC Data Source Administrator. The same error came out.
Below are some of my specifications:
Platform: Windows 7 64bit
Oracle: Oracle Database 11g Release 2 (64bit)
Unity: 4.1.2
Can someone please help me with this? What is it that i have done wrong?
Thanks.

whenever localhost (127.0.0.1) is used, this means that no remote client can ever connect to this system
The problem involves ODBC configuration & has nothing to do with Oracle.

Help for getting connection with oracle database

Hello,
i have a problem to connect my java program with oracle databse.
i have oracle 8 release. i tried all my best to connect but i
can't. please help me. whenever i compile JdbcCheckup.java file
which is distributed with oracle 8 release, it compile successfully.
but whenever i run JdbcCheckup class file then it will generate an
exception and that is -
Exception in thread "main" java.lang.ClassNotFoundException:
oracle.jdbc.driver.OracleDriver

at java.lang.class.forname(unknown source)
and some other error message.
But, by following yours given instruction, first, i unzip CLASSES111.zip
in file which is distributed with oracle 8 realease in jdbc subdirectory
into c:\temp directory and then run oracle installer(setup.exe) and point
the installer to c:\temp and then i install the oracle JDBC drivers(beta)
7.3.3.1.3 from the jdbc subfolder into oracle installer by selecting
win95.prd for jdbc subfolder.
After that i write into my autoexec.bat file,
path d:\jdk\lib;d:\jdk\bin;c:\windows\command;C:\temp\BIN;c:\temp\jdbc\lib\classes111.zip

path d:\jdk\lib;d:\jdk\bin;c:\windows\command;C:\temp\BIN;c:\temp\jdbc\lib\classes111.zipYou've added classes111.zip to your PATH, not your CLASSPATH.
Add it to your CLASSPATH using:

Help needed in setting up Japanese Database

Hi there,
Help needed in setting up Japanese Database.
I created database with UTF8 character set on Sun Solaris O/S.
Oracle version 8.1.7.
I am accessing the DB through SQL*Plus (Windows client).
I downloaded the Japanese font on client side and also set the NLS_LANG environment variable to Japanese_Japan.UTF8. Still, I am not able to view Japanese characters. O/S on client side is Windows 2000 professional (English). Is O/S (client) need to be Japanese O/S? When I try to retrieve sysdate, its displaying in Japanese but not all characters in Japanese. Can anyone help me out how to set up the client and is there any parameters to be setup at server side? I also tried to insert japanese characters into table through client, but it displaying as "?????" characters. Any help in this regard is appreciated.
Thanks in advance,
-Shankar

lol
your program is working just fine.
do you know what accept does? if not read below.
serversocket.accept() is where java stops and waits for a (client)socket to connect to it.
only after a socket has connected wil the program continue.
try putting the accept() in its own little thread and let it wait there while your program continues in another thread

Not able to connect remote oracle database over VPN

I can not connect remote oracle database over VPN. tnsping is ok and it shows the server information of remote database. i can also telnet the 1521 port of remote database server. I can connect the same server when it is located in the same LAN. Please help me out this is very urgent.

First, this is a forum of volunteers. There is no "urgent" here.
"Urgent" means one of two things -
1) people are dying, or
2) you have a customer-facing, revenue-producing production system that is down.
(And to get some perspective on the second case, keep the first in mind.)
For the first, you call whatever civil emergency service seems appropriate.
For the second, you open an SR with Oracle - which requires a paid-up support contract. For *them* to consider your problem "urgent", you will need to demonstrate that your problem falls under item #2. I seriously doubt your problem fits that criteria.
You don't have a support contract? Now you know the exact dollar figure that your company places on the data.
That said, you need to understand a few things about your specific problem,
First, port 1521 is only used by the listener to accept a connection request. Once it gets that request (and finds that it is for a service (sid) that it knows about, it will fork a server process and tell the requesting client that it can communicate with that server process over some other port .. a randomly chosen port number in the "high" range. It could be your vpn is blocking that other port, whereas your internal firewall is not.
But this is just an educated guess since I cannot find "can not connect remote oracle database over VPN" in any error message manual. If you had mentioned the VPN along with an actual oracle error message we could be much more precise in our diagnoses and recommendations.
---- edit 22 Sep
It occurred to me that I just assumed you were using the same client machine in both cases ... a laptop that you use both at work (local network) and home (vpn). If that assumption is false, there are probably problems with your tns setup on the home (vpn) machine.
But again, it would be much easier to help if you gave us an actual error message.

How to connect to Oracle database from webdynprojava application

Hi
How to connect to Oracle database from webdynprojava application. where can we provide the code to connect to database.?
Thank You.

Hi,
You need to create Java Bean model. The bean is a typical java bean with default constructor, getter and setter. You can have additional methods for query etc. The attributes in the class will be your model node and attributes.
However you need to configure the connection and create JNDI using visual administrator before writing the code.
You can also consider writing Session EJB with oracle and using them in WD.

OBIEE 11g not connect the Oracle database

Hi All,
We installed 11.1.1.6.0 version on Linux 64 bit it works fine after some reason we delete that one and re install on same Linux box,we place old catalog and rpd.
But when you login all reports is showing errors bellow

Pls help thanks in advance.

There are 2 places you need to keep TNS names.ora file for OBIEE to connect.
1. Oracle client which is in your machine
2. OBIEEhome>Oracle_BI1\network\admin
I'm sure you would have it in your oracle client. Copy paste the same TNS names in this path too.
Then open rpd and right click on any table in physical layer and click view data. You should see the results.
if this doesn't work check your credentials.
mark if this helps

Connect to Oracle database from SQL Sever

Can you help on an issue of connection from SQL Server to Oracle database:
In SQL Server, I create a "linked server" to connect to Oracle database on a different machine. But it will take a unreasonable time (about 30 seconds) to call a Oracle query from SQL Server.

No there are no entries required in the TNSNAMES.ORA
When you are using ODBC for connection, Oracle does not look fo rany enteries in TNSNAMES.ORA file.
Now I am able to connect to both SQL Plus and Forms 6i. But while connecting to SQL Plus its giving an error
Error accessing PRODUCT_USER_PROFILE
Warning: Product user profile information not loaded!
You may need to run PUPBLD.SQL as SYSTEM
Server not available or version too low for this feature
Connected to:
Oracle Open Client Adapter for ODBC 6.0.5.35.0
Microsoft SQL Server 08.00.0534
Also while disconnecting the Windows Program Error comes, and the application closes abruptly.

Oracle Client to connect to oracle database 7.x

Hi,
I want to connect to oracle database 7.x from a win2K using ODBC.
I know I need sql*net to make a connection .
Can you tell me where can I find it on the site to download/purchase?
If it is not available,can you suggest me the other options available for my situation.
Thanks
Sushma.

Thank You Justin.
Can you provide me the link to the download/purchasing the oracle client.
Because when I searched on OTN ,I get only documentation,nothing to software downloads.
I really need some help.
Is oracle client called as oracle tools etc.????????
Thanks in advance

Using php to connect to Oracle Database 11g Release 2 Enterprise Edition EE

define('ORA_CON_DB', '//localhost/EE'); // Connection identifier

Edited by: user11273096 on Jul 15, 2011 12:03 AM

Find the hostname and service name of the database and use those values in the ORA_CON_DB constant.
Use 'lsnrctl status' on the database host to find the service name.
If you use a "tns" alias, you may need to create a tnsnames.ora file where PHP can access it.
Set the environment variable TNS_ADMIN (on Linux) to the directory containing the file.

Help needed on installation of Oracle 9i on Sun Solaris 8

Hey,
Help needed on installation of Oracle 9i EE on Sun Solaris 8. The problem I met was: we followed the installation guide from the documentation. And we selected the choice "install software only". After it was done successfully, we run Database Configuration Assistant utility to create a database instance. But finally it always tried to create the instance at the root directory ( / ) which doesn't have enough space and then failed. The case was that we have set the enviroment parameters: $ORACLE_BASE = /export/mydata, $ORACLE_HOME = /export/apps/oracle9i. That means it should be installed at /export/mydata, but it didn't. Any help or advice are welcome. Thanks.
Simon

I have downloaded Oracle 11G R2 version from Windows and extracted it in Windows and copied it into DVD after extraction in two folders. Now I am mounting that DVD in Solaris 10 installed in my VMware . I made a new directory named as 'installation ' under /export/home/oracle and copied the folders from DVD to 'installation' folder. Now I am entering installation folder and try to do ./runInstaller as 'oracle ' user and getting the error mentioned before.

How to connect to oracle database from visual basic 2010 express edition

I have installed visual basic 2010 express edition on windows xp. But visual basic 2010 express edition supports Microsoft sql server database file,Microsoft sql server compact 3.5, Microsoft access database file. I want to connect to oracle database from visual basic 2010 express edition. So what drivers are required and how to do connectivity?

Hello,
I wasn't clear on what you were using to make the connection. I had a look in Visual Studio 2010 (don't have express to test sorry).
I think you mean the Data Sources available under the menu Data-> Datasources. this seems to match the description you give when I
look at the list of datasource options.
In here you can make ODBC connections via the Microsoft .net Data Provider .
If you select ODBC as a datasource you can see listed the DSN's you created - for example I see 2 which use the Oracle ODBC driver.
This assumes you installed an Oracle Client + the oracle version of the ODBC driver (comes with the oracle client).
Once you created a server connection then you should see it in the server explorer.
You can also download the Oracle Developer Tools for Visual Studio which is an add on for VS.
** I suspect this is only for VS 2010 and I didn't see that Express was supported.
http://www.oracle.com/technetwork/developer-tools/visual-studio/overview/index-097110.html
Let me know if that helps.
