***Checked for relevance on 01-MAY-2011***

Goal

The information below replaces Appendix E Cascaded Destinations of Oracle Data Guard Concepts and Administration 10g Release 2 (10.2) part number B14239.

This information also applies to Oracle10g Release 1 and Oracle9i releases.

For information on Cascaded Destinations in Data Guard 11g Release 1, please see Appendix E here.

For 11g Release 2, see Chapter 6 Redo Transport Services here.

Please note that as of Version 11.2.0.2 many of the restrictions with cascaded standby databases have been lifted. Please refer to the documentation link above for up to date information in 11.2.0.2 and cascaded standby databases.

Solution

Summary:

The significant changes from the previous Oracle Database 10g Release 2 documentation include:
  1. Cascading logical standby databases from a logical standby database is not supported.
  2. Cascading standby databases (logical or physical) from a primary database that is part of an Oracle Real Application Cluster (RAC) is not supported (This restriction has been lifted in 11.2.0.2)
  3. Using Cascaded standby databases in a Data Guard Broker environment is not supported.
