Hi Reinhard,

I can confirm absolutely that partial page writes do occur in the real world. 
We had to instances of this on one server within a few days. Unfortunately, we 
weren't able to recover. We had the server option MIRRORWRITE LOG set to the 
default of PARALLEL at the time, and the ADSM server did not recover as it 
should have. If we had had MIRRORWRITE LOG set to SEQUENTIAL, the database 
would have recovered, I believe. And there have been changes made to the 
recovery logic (sorry, I can't remember which version) that should enabled the 
database to recover even if set to PARALLEL.


regards,

Trevor
