If your Oracle Flash Storage System setup uses a firewall at either the primary LUN or the seconday LUN, ensure that the firewall on your operating system is configured to allow access to the required ports.
Transmission Control Protocol/Internet Protocol (TCP/IP) infrastructure is used for primary site and secondary site data protection. When TCP/IP is used for continuous data protection at the primary site, as with Oracle MaxRep for SAN, the communication of both the data and the configuration happens over the local area network (LAN). When TCP/IP is used to implement a remote Disaster Recovery (DR) solution, the communication of both the data and configuration happens over both the LAN link and the Wide Area Network (WAN) link.
