    Unanswered: Cache/pool usage

    If I have 8 GB cache with 5GB 2K io and 3GB 16K io pool, what would happen if
    1. I bind one large 7 GB table to this cache using select * from tablename and showplan shows 16 io is being used.
    >>> As per my understanding, 3GB of table will be bound to 16K pool and remaining 5GB will remain on disk using fetch & discard strategy.

    2. I bind multiple tables of total size of 7GB. Few tables will be bound to 16K pool and remaining will be bound to 2K pool. Now, if I run a query then although optimizer wants to use 16K io will have to use 2K io because tables are in 2K pool. Am I correct? If yes, then should we have large 16K io pool than 2K pool all the time?

    Thanks
