The image shows the architecture of a CMAN-TDM (CMAN-TDM) instance with connections between database applications and two Oracle Autonomous Database instances (Oracle DB
Instance 1 and Oracle Instance 2, each with PDB11 and PDB12).
The database applications can be with or without local connection pools. The following database applications have services
that flow to the CMAN-TDM instance:
- JDBC-Thin: Service 1
- Oracle Call Interface (OCI): Service 2
- ODP.NET: Service 3
- python-oracledb: Service 2
- node-oracledb: Service 2
The CMAN-TDM instance has a Default Set Cache, Dedicated Outbound Connections, and Proxy Resident Connection Pool (PRCP).
The following are the connections:
- Service 1 flows from JDBC-Thin through the Dedicated Outbound Connections to Oracle DB Instance 1, PDB11.
- Service 3 flows from ODP.NET through the Dedicated Outbound Connections to Oracle DB Instance 2, PDB11.
- Service 2 flows from OCI, python-oracledb, and node-oracledb through the PRCP to Oracle DB Instance 1, PDB12 and Oracle DB
Instance 2, PDB12.
