This note describes the procedure of configuring a cross platform using the 11g RMAN Active Duplicate as well as an Active Standby Database setup over a Windows and Linux platform.
The Metalink note Data Guard Support for Heterogeneous Primary and Physical Standbys in Same Data Guard Configuration [ID 413484.1] describes the supported cross platform combinations between a primary and standby database.
In Oracle 10g, we could have a 32 bit and 64 bit Primary/Standby combination on some supported platforms and in 11g this has been extended to cover heterogenous platforms for the Primary and Standby database.
The environment used is as follows:
Primary
Windows 7 64 bit
11g Release 2
DB_UNIQUE_NAME=orcl
Active Standby
Oracle Enterprise Linux 5.7 64 bit
11g Release 2
DB_UNIUE_NAME=orcl_dr
