About Receiver Service Paths

Receiver Service paths, also known as target-initiated distribution paths, initiates a path from the target deployment to the Distribution Service on the source and pull trail files.

The Receiver Service Paths create a target initiated path for environments such as Demilitarized Zone Paths (DMZ) or Cloud to on-premise, where the Distribution Service Paths in the source Oracle GoldenGate deployment cannot open network connections in the target environment to the Receiver Service Path due to network security policies.

If the Distribution Service Path cannot initiate connections to the Receiver Service Path, but Receiver Service Path can initiate a connection to the machine running the Distribution Service Path, then the Receiver Service Path establishes a secure or non-secure target initiated path through a firewall or Demilitarized (DMZ) zone using Oracle GoldenGate and pulls the requested trail files.

The Receiver Service Path endpoints display that the retrieval of the trail files was initiated by the Receiver Service Path.

The wss protocol must be specified whenever the source deployment (Distribution Service host) has been configured with security enabled. The secured communication channel can be created using an SSL certificate in a client Wallet, even if the target deployment (Receiver Service host) has disabled security.

For Receiver Service Paths, the use case for the ws and wss protocols is explained in the following table:

Limitations of Using Receiver Service Paths

Here are the limitations when working with Receiver Service Paths:

  • There is no support for interaction between legacy and secure deployments using this mode of operation for target-initiated distribution paths.

  • No support for ogg protocol. Only ws and wss protocols are supported.

  • It is possible to only get information and stop a target-initiated distribution path on Distribution Service and after the path stops, it is not be visible on the Distribution Service.
