Data Guard for Ebusiness Suite.‏

Data Guard for Ebusiness Suite.‏
There is a metalink note which covers the data guard for e-business suite. The main message is that Data Guard is not very different when it sits with the ebusiness sutie. Data guard remains generic whatever configuration you may choose.
Below are some metalink notes for dataguard with EBS.
For 11i (341437.1)
For R12 (452056.1)
403347.1 is also helpful

The other major bit need to remember is that data guard is only for data changes. It can’t replicate or propagate the applications changes. E.g. you apply a ebusiness suite patch to Prod , the database changes would be synched to DR but not the application changes.

Same way if you apply a RDBMS patch or OPATCH which changes the database binaries , this will not be propagated to DR.

So for the application update you need to look for another solution. We use RSYCN at most of our places which is an operating system feature. It keeps monitoring the files and as for a file verision is updated , it will push it through to DR.
