Network

The following network resources must be available to support Oracle GoldenGate.

• For optimal performance and reliability, especially in maintaining low latency on the target, use the fastest network possible and install redundancies at all points of failure.

• You can configure Oracle GoldenGate Microservices Architecture to use a reverse proxy. Oracle GoldenGate MA includes a script called ReverseProxySettings that generates configuration file for only the NGINX reverse proxy server.

  See Reverse Proxy Support in Securing the Oracle GoldenGate Environment.

• Configure the system to use both TCP and UDP services, including DNS. Oracle GoldenGate supports IPv4 and IPv6 and can operate in a system that supports one or both of these protocols.

• Configure the network with the host names or IP addresses of all systems that will be hosting Oracle GoldenGate processes and to which Oracle GoldenGate will be connecting.

• Oracle GoldenGate requires some unreserved and unrestricted TCP/IP network ports, the number of which depends on the number and types of processes in your configuration. See Administering Oracle GoldenGate for details on how to configure the Manager process to handle the required ports.

• Keep a record of the ports that you assigned to Oracle GoldenGate processes. You specify them with parameters when configuring deployments for the Microservices Architecture and for the Manager and pumps with the Classic Architecture.

• Configure your firewalls to accept connections through the Oracle GoldenGate ports.
