While doing full table scan, Buffer Cache KEEP pool is not being used to read the blocks of a (KEEP) table which size is >10% of DB_KEEP_CACHE_SIZE.
These blocks are always being read through DIRECT READ, which can cause performance problem due to non-caching / re-reading of keep object blocks.
Upgraded to 11g.
