The SID of the gateway ( SID_NAME) must be the same in listener.ora and tnsnames.ora. (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))Īdd an entry to the listener.ora file to start the gateway in response to connection requests. The following example is the address on which the Oracle Net Listener listens ( HOST is the address of the machine on which the gateway is installed): LISTENER = Information about the gateway must be added to the listener.ora configuration file which is located in the ORACLE_HOME\NETWORK\ADMIN\ directory.
After creating the file, set the HS_FDS_CONNECT_INFO parameter to the system DSN that you created earlier, for example: HS_FDS_CONNECT_INFO=PostgreSQL Configure Oracle Net ListenerĪfter configuring the gateway, you need to configure Oracle Net Listener to communicate with the Oracle database. You need a separate initialization file for each ODBC data source. The name must be prefixed with init - for example, initPostgreSQL.ora.
To create an initialization file for the gateway, copy the sample initialization file and rename it. The sample file initdg4odbc.ora is stored in the ORACLE_HOME\hs\admin directory.

Configure the Initialization FileĪfter installing the gateway and the ODBC driver for PostgreSQL, create an initialization file for your Oracle Database Gateway for ODBC. The gateway can be installed on the machine running the non-Oracle system, the machine running the Oracle database or on a third machine as a standalone. The non-Oracle system can run on the same machine as the Oracle server or on a different machine. The driver must be installed on the same machine as the gateway. Any ODBC-compatible data source can be accessed using the gateway and the appropriate ODBC driver. The gateway works with an ODBC driver to access non-Oracle systems or other, remote Oracle servers. If your data is stored in a non-Oracle database system or cloud application, and you need to access it from an Oracle Database server, you can create a database link to an Oracle Database Gateway for ODBC.
