Thanks Gopal.
So, due to the fact that V$GC_ELEMENT is based on X$LE and V$DLM_RESS (OPS) is now known as V$GE_RESOURCE (RAC) and is based on X$LE, therefore, somehow this information can be extracted from V$GC_ELEMENT and V$GE_RESOURCE?
In my opinion, Oracle should do a better job in documenting these things so that those who don't have access to Oracle's internal sites (like most of us) can get this information relatively easily.

Amir,

I am discusing the very same issue in my upcoming RAC book. Basically to understand the master of the block, you need to convert the block/buffer name to a to the resource name (combination of X$LE, DLM_RES , GC_ELEMENT and X$KJBR).

BTW Dynamic Remastering not enabled by default in 9iR2 and it is not totally functional. For that matter, even in 10gR1 it is not a true dynamic remastering as it masters the files to the instance and not the objects. Only 10gR2 has the object level dynamic remastering and for testing purpose you can manually remaster the objects using the oradebug lkdebug commands.
