Hi,
With Oracle 10g R2, is it now possible to implement a Dataguard Physical Standby solution between two different OS platforms but same Oracle version and Patchset. For example
Between HPUX 11.11 and Redhat Linux Enterprise
or
Between HPUX 11.11 and Windows 2003 Enterprise
Your response is appreciated.

I dont think its possible , see this excerpt from 10g docs

2.3.1 Hardware and Operating System Requirements
■ All members of a Data Guard configuration must run an Oracle image that is built for the same platform.For example, this means a Data Guard configuration with a primary database on a 32-bit Linux on Intel system can have a standby database that is configured on a 32-bit Linux on Intel system. However, a primary database on a 64-bit HP-UX system can also be configured with a standby database on a 32-bit HP-UX system,as long as both servers are running 32-bit images.
■ The hardware (for example, the number of CPUs, memory size, storage configuration) can be different between the primary and standby systems. If the standby system is smaller than the primary system, you may have to restrict the work that can be done on the standby system after a switchover or failover.The standby system must have enough resources available to receive and apply all redo data from the primary database. The logical standby database requires additional resources to translate the redo data into SQL statements and then execute the SQL on the logical standby database.
■ The operating system running on the primary and standby locations must be the same, but the operating system release does not need to be the same. In addition, the standby database can use a different directory structure from the primary database.
