I'm beginner level oracle developer. I have SQL developer installed on my machine. And I wanted to install Toad for oracle too. But When I tried to install Toad, it gave me an error:
No Valid Oracle Clients found. You need atleast one 64- bit client properly configured.
Can someone explain why I'm getting this error?
Because SQL Developer ships with its own JDBC driver, which doesn't require an oracle client to connect to the Database.
If you have a compatible Oracle Client sitting around, you can tell SQL Developer to piggyback on that client for connections - but THAT IS NOT required.
T.O.A.D. is a windows executable that needs an Oracle Client to connect to a database. An Instant Client is the easiest way to get going.

I have Windows 8 and Oracle SQL Developer. When I tried to connect to a remote server, it give me v$session.osuser error and vendor code 17190.
Do anyone know what this means? I have tried to search for the vendor code 17190 but nothing related to Oracle.
Thanks
I have downloaded the oracle instant client 12_1 but i'm unable to connect to the oracle database.when i tried using sql developer it is displaying the following error.
The Network could not be established.
I'm using windows 7 and my Oracle_home path is defautly set in the system variables as
path
E:\app\dell\product\11.2.0\dbhome\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\
I suspect you've begun the headache of messing with the connection string. I seriously recommend you find the option in SQL Developer that will allow you to connect directly to the server (bypass TNSNAMES) and use EZ Connect. The connection string will look like this:
server.whatevz.com:port/sidname
I don't use SQL Developer, so I can't point to it specifically, but I have used it and configured it as such, and it works fine. I'm a fan of PL/SQL Developer (All Around Automation) myself.
Can you help me connect access 2013 with an Oracle database using odbc. I need a Oracle in oraclient10g driver, however I do not know how to install it. I went through many descriptions how to install that driver.
I have the database i just need to connect it to Access for a school project.
I have to create win32 client on Delphi, which can work with database on Oracle. The only problem with this task that client have to demand "zero administration".
In other words user downloaded it from our site and ran it without any installing oracle client and tuning tnsnames.ora.
My first aproach was to install apache on server side with connection to Oracle. Our win32 client this case is like web brouser works with Oracle via https.
It works but performance is not so good as expected. Delay in reaction between clent and server side is too long.
Is there any way to acheve my goal (zero adminstration client with good enough performance)?
The product ODAC (Oracle Data Access Components) from DevArt has a "no oracle client needed" mode. This would probably be the easiest solution. You could also just include the Oracle Instant Client with your product and use Oracle's "EZConnect" syntax so that you don't have to configure anything on the client. Using EZConnect allows you to connect to an Oracle Database without using a TNSNames.ora file.
I recently upgraded my oracle client to 10g (10.2.0.1.0).
Now when I try to connect to a legacy 8.0 database, I get
ORA-03134: Connections to this server version are no longer supported.
Is there any workaround for this problem, or do I have to install two clients on my local machine?
Yes, you can connect to an Oracle 8i database with the 10g client, but the 8i Database requires the 8.1.7.3 patchset, which you can get from Oracle's Metalink support site (requires login).
Here's an Oracle forum post with the details.
If updating your Oracle Database isn't an option, then you can have 2 different clients installed (in different "Oracle Homes" (or directories), and use the selecthome.bat file to switch between your installed clients.
For example, before connecting to 8i, you'd run:
C:\Oracle\Client1_8i\bin\selecthome.bat
or this to use your Oracle 10g client:
C:\Oracle\Client2_10g\bin\selecthome.bat
I had to connect a C# code to an Oracle 7 (I know you it's 8...)... the only way I get it was to get the CD to install the Oracle Server and to go in the "Optional Configuration Component" and to use the Oracle73 Ver2.5.
I think you should go check the CD of the Oracle 8 Server and check if an ODBC is still available.
The best way to connect an Oracle 8.1.7 and higher is through Instant Client. Download Instant client 10.2 from oracle site, copy all files in the same folder where .NET assemblies resides and use classes located in System.Data.OracleClient. This work for me in .NET 4 project and oracle DB 8.1.7 server.
