...or an ungentle way, in the event the mechanism is truly being used for H/A or D/R, instead of migration... :-)

As Carel-Jan already said, I am wondering too why would one use "heterogeneous DG" systems on different oracle platforms (linux-windoz) and specially systems with different "endian-ness" (irrespective of if this is supported or not). If someone on the list have such configuration, I would like to hear the reasons for this.

goran

Thank you for the response.  I'm aware that DG can generically be configured with different storage.  Specifically, I was asking about the "heterogeneous DG" capability in 11g, mentioned earlier in this email thread.  In order to deal with cross-platform issues such as "endian-ness", I am asking if there are any special prerequisites such as ASM required?

Tim,
you can DG between ASM and non-ASM systems, as you can between RAC ans SI dbs.

Is ASM required as storage on all nodes?  I would expect so, but just asking....

Williams,

Heterogeneous Data Guard Configuration is supported starting with 11g which allows a mix of Linux and Windows primary and standby databases in the same Data Guard configuration.
