Software components
At a high level, Netezza Performance Server consists of two major software components that are running on Cloud Pak for Data System.
- Netezza Performance Server node
The Netezza Performance Server node is deployed inside the OpenShift cluster that runs on Cloud Pak For Data System. The core functions of Netezza Replication Services, such as Database Change Capture and Database Apply, run on a Netezza Performance Server. The captured changes are queued for Replication Queue Manager (RQM). The changes that are received from the remote Netezza Performance Server node through the RQM are applied on the local Netezza Performance Server node.
- Replication Queue Manager (RQM)
The Replication Queue Manager runs as an OpenShift service within the Cloud Pak For Data System where the Netezza Performance Server node is hosted. It compresses and sends the database changes from the local Netezza Performance Server node to the remote Netezza Performance Server node. The RQM that runs on the remote NPS node receives the replication packets, decompresses them, and queues them up for the remote Netezza Performance Server node to apply them.
