This update improves and fixes the following issues when you use a Real Application Clusters (Oracle RAC) environment in Microsoft SQL Server:

  • Improvements to Change Data Capture (CDC) to be more tolerable when an RAC node goes down and then restarts.

    ORACDC517E:Oracle Call Interface (OCI) method failed: ORA-00904: "NEXT_CHANGE#": invalid identifier
