# Setting up CDC in Oracle Redo/Archive log mode

The Oracle Redo/Archive log mode used in Talend is equivalent to the archive log mode of Oracle.

Information noteNote: Oracle v10 and previous versions are not supported. Oracle v11 and the Redo/Archive log mode for Oracle are deprecated.

The following three sections detail the prerequisites for using CDC in Redo/Archive log mode for Oracle databases and provide a two-step example of how to set up a CDC environment using the Oracle Redo/Archive log mode in Talend Studio: the first step explains how to configure your system for CDC and the second, how to extract the modified data.
