Issues fixed in this release

The following issues were fixed in this release:

In a PostgreSQL database, some datatypes are not supported when replicating data to an IBM watsonx.data™ target data store

Issue: In a PostgreSQL database, columns with a UUID datatype are not supported when replicating data to an IBM watsonx.data target data store
Resolution: Columns with a UUID datatype are replicated to a target watsonx.data data store.

Some configuration parameters are ignored when replicating to IBM watsonx.data

Issue: Replication asset settings, such as replication data file prefix and thresholds that determine when and how Data Replication commits data, do not take effect.
Resolution: All replication asset settings are applied when you replicate data to a watsonx.data target.

New features

This release of Data Replication includes the following features:

Audit logging

Data Replication now integrates with the IBM Software Hub audit logging service. Auditable events for Data Replication are forwarded to the security information and event management (SIEM) solution that you integrate with.

For more information, see:

Add multiple licenses to your Data Replication service installation

If you have more than one replication license and want to gain access to all of the capabilities provided by your licenses within the same IBM Software Hub instance, you can now add these licenses to your Data Replication service installation as replication extensions. For details, see Extending Data Replication capabilities.

Use an IBM Data Replication Access Server connection for replicating data between remote source and target data stores in your project

You can now replicate data between remote source and target data stores with the Data Replication service by using an IBM Data Replication Access Server connection to a remote Change Data Capture (CDC) replication engines deployment.

For details, see Setting up remote CDC replication.

Use IBM Db2 for z/OS as a source data store for replicating data in your project

You can now replicate data from IBM Db2 for z/OS with the Data Replication service.

Use IBM Db2 Database as a source data store for replicating data in your project

You can now replicate data from IBM Db2 Database with the Data Replication service.

Use IBM watsonx.data as a target data store for replicating data in your project

You can now replicate data to watsonx.data with the Data Replication service.

To read more about these features, see What's new and changed in Data Replication in the IBM Cloud Pak for Data documentation.
