What is TNS service name in ODBC?
Create a TNS (Transparent Network Substrate) Service Name (also called a Net Service Name) on a computer where an Oracle client is installed if the Tivoli Data Warehouse exists on a remote Oracle server. The TNS Service name is needed to create an ODBC connection between the client and the server.
What are the components of ODBC?
The ODBC architecture has four components:
- Application. Performs processing and calls ODBC functions to submit SQL statements and retrieve results.
- Driver Manager. Loads and unloads drivers on behalf of an application.
- Driver.
- Data source.
What is Oracle DSN?
An ODBC Data Source Name (DSN) stores information for establishing a connection to a database on a remote database server. A system DSN provides access to multiple users, rather than only the user who created it.
What is Oracle Tnsnames?
A TNS (Transparent Network Substrate) name is the name of the entry in tnsnames.ora file which is kept in $ORACLE_HOME/network/admin. This file contains the information which is used by the system to connect to oracle database. Using this a client can fetch server associated information transparently.
What are the advantages of ODBC?
Some of the advantages of ODBC are:
- ODBC provides a consistent interface regardless of the kind of database server used.
- You can have more than one concurrent connection.
- Applications do not have to be bound to each database on which they will run.
Why is ODBC important?
Open Database Connectivity—or ODBC—is an application programming interface (API) that lets software connect with database management systems while remaining independent of them. This is important, because it allows applications to interact with multiple databases simultaneously using SQL (Structured Query Language).
