This image shows the subnets, ports, and data flows of the secondary,
stand-by environment on Oracle Cloud Infrastructure (OCI).
The OCI Region has a VCN and a single Availability Domain. There is one
public subnet and 3 private subnets. The following are located in the secondary data
center:
- Public Subnet 1 (web tier): Load balancer (100.100.100.10) and
optionally WebHost1 and Webhost 2
- WebHost1 (10.10.10.11) and WebHost2 (10.10.10.12)
- Private Subnet 2 (mid-tier): SOAHost1 (100.70.10.13) and SOAHost2
(100.70.10.14), both SOA Hosts are running on an OCI VM.
- Private Subnet 3 (FSS-tier): OCI FSS (5): products1, products2, and
Config runtime
- Private Subnet 4 (db-tier): DB System (RAC) with DBHost1 (100.80.10.15)
and DBHost2 (100.80.10.16) and PDB1
The following port connections link the primary and secondary data
centers:
- A DNS uses port 443 and https to connect the primary and secondary
environments.
- Data Guard uses Port 1521 (SQL*NET) to connect the primary PDB database
with the secondary PDB.
- Port 22 and https connects the primary and secondary SOA hosts.
- The secondary Load Balancer uses ports 443 (HTTPS), 7001 (HTTP Console),
and 8888 (HTTP internal wsm) on the web tier. Content flows from the Load Balancer
to the SOA Host in the mid-tier using ports 7001 (HTTP Admin), 7010 (HTTP wsm), 8001
(HTTP soa), 8011 (HTTP osb), 8021 (HTTP ess), and 9001 (HTTP bam).
- A two-way connection uses NFS to link the mid-tier with the FSS
tier.
- The secondary SOA Hosts in the mid-tier use ports 1521 (SQL*NET) and
6200 (ONS) to connect to the db-tier.
The components are described in more detail in the surrounding text.
