Message-ID: <4799a1f3$0$1345$> on RH Linux 4.0, update 4, 2 node RAC. I am experimenting with ASM parameters, DB_CACHE_SIZE and DB_FILE_MULTIBLOCK_READ_COUNT. Default cache size is 25M, MBRC is 110. Default block size is 4k. I have set cache size to 128M, MBRC to 256 (1M reads). I tried going above 1M, but the parameter was ignored. RMAN seems to work much faster, benchmark is in progress. Does anybody have any recommendations or experiences to share?
