This image shows a hybrid disaster recovery environment where the
primary SOA hosts, database hosts, and databases are on-premises. The
secondary, stand-by environment is on OCI.
The following are located in the on-premises data center:
- Load balancer (10.10.10.10)
- WebHost1 (10.10.10.11) and WebHost2 (10.10.10.12)
- Oracle SOA Suite with SOAHost1 (10.10.10.13) and SOAHost2
(10.10.10.14)
- Oracle RAC with DBHost1 (10.10.10.15) and DBHost2 (10.10.10.16) and
PDB1
- Customer on-premises equipment (CPE) with a FastConnect connection to
the DRG in the cloud VCN
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)
- 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), and 8021 (HTTP ess).
- 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.
