External JRE support and integration

Hybrid Data Pipeline uses an embedded JRE at runtime. However, you can integrate an external JRE with a standing deployment of Hybrid Data Pipeline. The following JREs are currently supported.
*Oracle Java 8 JRE
*OpenJDK 8 JRE
Hybrid Data Pipeline must be installed on at least one server before you proceed with integrating an external JRE. Files associated with the embedded JRE can then be used to modify the external JRE you wish to use with the Hybrid Data Pipeline server or the On-Premises Connector.
Note: Using an external JRE with the server is exclusive from using an external JRE with the On-Premises Connector. That is, the server can run on an external JRE while the On-Premises Connector runs on the embedded JRE, and vice versa.
The following work flow outlines the procedure for integrating an external JRE. See the corresponding topics for details.
1. Modify the external JRE.
*Option 1. Non-FIPS environment.
*Option 2. FIPS environment.
FIPS is not supported for the On-Premises Connector with either embedded or external JREs.
2. If integrating the external JRE with the server, configure the server to use the JRE.
3. If integrating the external JRE with the On-Premises Connector, configure the connector to use the JRE.
* Modify the external JRE for a non-FIPS environment
* Modify the external JRE for a FIPS environment
* Configure the server to use the external JRE
* Configure the On-Premises Connector to use the external JRE
