Configure the gateway using initialization parameters. This is done by creating an initialization file and setting the desired parameters in this file. See Heterogeneous Services Configuration Information for configuration information.
Heterogeneous Services initialization parameters are distinct from Oracle Database initialization parameters. Heterogeneous Services initialization parameters are set in the Heterogeneous Services initialization file and not in the Oracle database initialization parameter file (init.ora file). There is a Heterogeneous Services initialization file for each gateway instance.
