Prerequisites for Creating a Replicat

Review the Installing the DataDirect driver for PostgreSQL in Installing Oracle GoldenGate and ensure that the DataDirect drivers are installed correctly, which varies depending on the operating system.

Ensure that the PostgreSQL Client Authentication Configuration file, $PGDATA/pg_hba.conf, on the database server is configured to allow connections from the Oracle GoldenGate server, if installed remotely. See https://www.postgresql.org/docs/13/auth-pg-hba-conf.html for more information.
