I'm trying to connect using different ODBC clients (Advanced query tools and ODBC Query Tool) to my remote Oracle database but every time getting the following error : ORA-12560: TNS:protocol adapter error
my connection settings are:
Driver={Microsoft ODBC for Oracle};dbq=192.168.10.11:1521/TEST_DB;Uid=username;Pwd=password;
Could you please explain what is wrong in my connection settings or am I need to configure something else?
Somewhere in your connection string, the Oracle SID or Service Name needs to be specified. The following are two examples, with one specifying SERVICE_NAME and the other specifying SID:
Driver={Microsoft ODBC for Oracle};Server=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=199.199.199.199)(PORT=1523))(CONNECT_DATA=(SID=dbName)));Uid=myUsername;Pwd=myPassword;
Driver={Microsoft ODBC for Oracle};Server=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=199.199.199.199)(PORT=1523))(CONNECT_DATA=(SERVICE_NAME=dbName)));Uid=myUsername;Pwd=myPassword;
Check your driver documentation to make sure you are including all of the required connection options. I believe the minimum required details are server, port, SID or SERVICE Name, UID, and PWD.

Driver={Microsoft ODBC for Oracle};
CONNECTSTRING=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=server)(PORT=7001))(CONNECT_DATA=(SERVICE_NAME=myDb)));
Uid=myUsername;Pwd=myPassword;

In Oracle, I have a 32-bit driver to connect in my 32-bit ODBC Oracle in OraClient11g_home1.
I want to connect using host, port, service-name, uid, pwd (as I do in Oracle SQL Developer). But the only versions of connection string that I can find use TNSNames.ora, which I can't modify.
For example I found this connection string:
Driver={Oracle in OraClient11g_home1};Dbq=myTNSServiceName;Uid=myUsername;Pwd=myPassword;
But dbq here is a TNS name. How can I modify this connection string to include host, port, and service-name?
Edit:
I also tried this:
"Driver={Oracle in OraClient11g_home1};SERVER=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort))(CONNECT_DATA=(SERVICE_NAME=MyOracleSID)));uid=myUsername;pwd=myPassword;"
But I got an error:
[RODBC] ERROR: state HY000, code 12560, message [Oracle][ODBC][Ora]ORA-12560: TNS:protocol adapter error
Please try this:
'DRIVER={Oracle in OraClient11g_home1};DBQ=x.x.x.x:MyPort/MySID;UID=username;PWD=password'
First SQL Developer connect via JDBC not ODBC.
Are you using SID or service name to connect?
DB Version? Os?
You are using an old terrible (32bit) and unsupported version anymore as far as i know full of bugs.
Try to think about it but in any case try to replace SERVER= with CONNECTSTRING= or SERVICE_NAME with SID
I need to connect my Microsoft Report Builder to Oracle DB but I could not seem to find the correct connection string for Oracle.
I tried:
Specifying username and password
Data Source=MyOracleDB;User Id=myUsername;Password=myPassword;Integrated Security=no;
but it returned:
Is it saying that I need to download the Oracle driver? Or should I get the connection string for Oracle DB?
If you don't already have it, you will need the Oracle Client installed. It will include an ODBC driver. ODBC is a wrapper for the Oracle Client, not a replacement. When setting up your connection you will also need to get the connection properties from the DBA (e.g. hostname/ip address, port, service name, username and password).

I am using Python3.6 and pyodbc to try and connect to Teradata. I need this for a script I want to hand off to an end user to update from data. I would prefer that each user not have to be instructed to setup their own DSN connection with a specific name I hard encode into the script.
I think I have the driver correct now as well as the server and DB name. What I can't figure out is how to get the connection string to not require a username and password.
Helpful info:
This is for windows OS. When I go to ODBC connections in windows, connection mechanism is listed as LDAP and i can connect through the Teradata program as well.
What does work:
Connection directly through the Teradata program (showing Teradata itself knows who I am)
Using DSN="DSN_name" where DSN_Name is the name under ODBC connections found in windows. Showing I can connect via DSN.
-Looking at ODBC Data Source Admin shows Driver matches what I have. "Server Name or ID" matches "servername" below.
Tried:
connect_string = 'Driver={Teradata Database ODBC Driver
16.20};DBCName=servername;Database=db_name;MechanismName=LDAP;UseIntegratedSecurity=1;'
con = pyodbc.connect(connect_string)
which gives:
pyodbc.Error: ('HY000', '[HY000] [Teradata][ODBC] (11210) Operation not allowed during the transaction state. (11210) (SQLExecDirectW)')
connect_string = 'Driver={Teradata Database ODBC Driver
16.20};DBCName=servername;Database=db_name;MechanismName=LDAP;'
con = pyodbc.connect(connect_string)
or
connect_string = 'Driver={Teradata Database ODBC Driver
16.20};DBCName=servername;Database=db_name;Authentication=LDAP;'
con = pyodbc.connect(connect_string)
which gives:
pyodbc.InterfaceError: ('28000', '[28000] [Teradata][ODBC Teradata Driver] (2) Unable to logon with Authentication Mechanism selected. (2) (SQLDriverConnect)')
I have also tried a few other suggested authentication mechanisms in addition to LDAP, but this is the one listed in Teradata and ODBC connections.
In SQL_Server I use something like trusted_connection=yes to achieve the same effect I desire which doesn't seem to work in the above examples.
error:
pyodbc.OperationalError: ('08001', '[08001] [Teradata][ODBC] (10380) Unable to establish connection
with data source. Missing settings: {[Password] [Username]} (10380) (SQLDriverConnect)')
I'm not an Oracle guy, but I find that I need to touch on some oracle resources to respond to a new report request. I'm working at an office where the connection to an oracle server uses LDAP and I can't get to the connection info. I do have an ODBC connection on my machine, so I can get into the database through MS Access. But I'd like to be able to connect with SQL Developer so I can do more useful profiling on the tables.
Is there any way to use my ODBC connection through Access to tease out Hostname, Port, and SID/Service name so I can connect through SQL Developer?
It seems I do not have permissions to the UTL_INADDR functions.
Since you have an ODBC connection defined already, you can open the ODBC Data Source Administrator on your computer (Goto the start menu and type ODBC in to search for it).
In the ODBC Data Source Administrator select the data source for the database in question (it may be on the User, System or File DSN tab) and click the Configure button.
From the Configuration screen you will be able to see the TNS Service Name for the connection.
The TNS Service Name should be all you'll need to supply to SQL Developer when creating the connection. Aside from your account credentials of course.
You can query SID and Hostname like this:
select instance_name, host_name from v$instance;
Afaik there is no way to query the port name from the database, see also this article on Ask TOM on this subject:
You cannot get the port -- the port is not necessarily known to the
database. The listener need not be running on the same machine with
the database, a single listener might be servicing many databases. A
database may have many listeners servicing it.
I have a problem with installing ODBC driver under Windows (7, 64bit) to connect to Oracle database. They kind of work - I mean I can define a DSN entry and open connection using "DSN=foobar" connection string but I can't use something more generic like passing full connection string to OdbcConnection or basing it on tnsnames.ora file. In both cases I get
"Data source name not found and no default driver specified"
What client software are you using? The answer is probably going to be, use ADO
