Setting up remote CDC replication

You can set up the remote Change Data Capture engines to extend the capabilities of your Data Replication service.

About this task

Data Replication supports a select set of highly used sources and targets natively. In addition to the native sources and targets, you can deploy Remote Change Data Capture (CDC) replication engines to extend the capabilities of Data Replication. In a remote CDC engine deployment, you can use the cloud-native replication control plane to operate and monitor the remote CDC engines by creating a connection to the Data Replication Access server from your Data Replication service instance in IBM® Software Hub.

The Access Server works with the Remote Change Data Capture (CDC) source and target engines, which allows you to:
  • Create CDC subscriptions from the replication control plane
  • Start, stop, pause, resume, and view the status of a replication from the dashboard
  • Control additional configurations by using the CDC Management Console

Remote CDC engines allow high throughput and performance and alleviate data sovereignty and data privacy concerns by processing the data where it resides. For more details on supported remote CDC replication deployment options, see CDC product overview and system requirements.

Before you begin

  1. To review what is required to set up remote CDC replication, see About CDC replication
  2. Identify the source and target data stores. You will need to collaborate with other administrators to set up remote CDC data stores. For details, see Supported sources and targets

Procedure

Follow these steps to ensure your remote IBM Change Data Capture (CDC) replication environment is ready to use:
  1. To begin using the CDC Replication, you must install three components: Management Console, Access Server, and one or more CDC Replication engines, see Deploy CDC source and target datastore
  2. To create and configure the data store in Access Server, see Configure the datastore in Access Server
  3. Provide data store access to the Access Server user, see Giving access to data stores

Supported sources and targets

You can review the requirements for each of the supported source and target engines in the InfoSphere documentation:

What to do next

You can now replicate data by using the Data Replication service and remote CDC replication. For more information, see Getting started with Data Replication.
