RE: Use of Multiple BLOCK Sizes ?

Vivek,  

    You also need to consider what the impact of multiple block sizes will do to your overall memory utilization. To use multiple block sizes you need to set DB_nK_CACHE_SIZE which reserves memory from your SGA and DB_CACHE specifically for that tablespace(s). While a part of that specific application might benefit from the larger block size the rest of it and your database in general may suffer.
