RE: db_file_multiblock_read_count 10g default values
Date: Thu, 5 Nov 2009 15:33:12 -0700
After a little more fiddling, it looks like the formula is calculated at instance startup as:
db_file_multiblock_read_count = db_cache_size/processes/9600, with a max of .28% of the db_cache_size
I'm not sure where that constant 9600 comes from, but I'd guess it's based on db_block_size (8192 in my case) plus some other overhead.
