Re: Any Oracle 9i Data Guard limitations specific to Linux implementations?

I've done sync physical DG on linux (over direct gigabit ethernet). Didn't encounter any serious problems.
With physical standby you can forget about nologging operations -> use alter database force logging or at least on tablespace level for important tablespaces.
Also I set LGWR running on higher priority on primary in order to transfer log records to standby with smallest latency.

Go with async if your business requirements allow you to lose few bits of data in case of disaster on primary (especially when servers aren't connected via low-latency high-throughput network).

And logical standby is only a prototype yet.

etc.), I am wondering if anybody on the list knows (from experience) of any specific limitations (e.g., bugs, etc.) that may be encountered while using the Data Guard (logical or physical standby databases and synchronous or asynchronous modes) implementation on Linux? In other words, looking for any information about possible limitations (or special workarounds needed) using Data Guard on a Linux implementation.
