  • Use an Easy Connect string that specifies the connection details for your Oracle Database server in a single line, such as "host:port/service_name".



  • Use one of the client components that you installed to connect to your Oracle Database server using the service name that you created. For example:



  • To use SQL*Plus, open a command prompt and type "sqlplus username/password@service_name".



  • To use OCI or OCCI, write a C or C++ program that uses these APIs and compile and run it with the appropriate libraries and headers from your client folder.



  • To use JDBC-OCI, write a Java program that uses this driver and run it with the appropriate classpath and system properties from your client folder.



  • To use ODBC, create a data source name (DSN) using the ODBC Data Source Administrator tool and use it with any ODBC-enabled application.
