Thanks Justin. I also checked and thought that it might also be possible with 
other OS like Solaris and AIX.

I believe Metalink Doc ID 413484.1 Data Guard Support for Heterogeneous Primary 
and Standby Systems in the Same Data Guard Configuration is the canonical 
reference for what configurations are allowed depending on the Oracle version.
Unfortunately, an AIX primary is only compatible with an AIX standby.  On the 
other hand, a Linux x86 box can have a Windows standby database.

Is it correct to say that I can have Datagaurd where Primary is AIX and 
Dataguard (Logical) is Linux. Is this Correct to say that Physical Standby is 
not possible but Logical Standby is possible. Any caveat.
