Before you begin:
- The Hybrid Data Pipeline deployment should be backed up according to Backing up Hybrid Data Pipeline deployments.
- You should have the installation program for the version of the product you are currently using.
About this task:
To replace a failed node, you must install the Hybrid Data Pipeline server on a new host machine and configure your network load balancer to use the new node. In addition, references and routing information related to the failed node should be removed from the load balancer configuration.
Note that during the initial installation of the Hybrid Data Pipeline server, the installer writes properties files, encryption keys, and system information to the key location. When performing subsequent installations on additional nodes, the key location must be specified to ensure consistent configuration of the service across nodes. For installations on additional nodes, the installer bypasses prompts for load balancing, SSL, system database, and On-Premises Connector configurations, as this information is provided by the files written to the key location.
What to do next:
Monitor your environment to ensure that requests are being distributed by the load balancer and results are being properly returned to client applications.
