    Cool

    Increase the DB_BLOCK_BUFFERS parameter in init.ora file and restart your instance.

    Make sure that you have at least DB_BLOCK_BUFFERS >= 4*PROCESSES in order to avoid ORA-00379 error. That is because each Oracle process can pin up to from 4 to DB_BLOCK_BUFFERS/PROCESSES number of buffers at any time.

    Hope that helps,

    You can increase DB_BLOCK_BUFFERS value in initial file. Block buffer is used to store updated data blocks.

    Well, the non-updated data blocks are also stored in the cache.
