ORA-00381: cannot use both new and old parameters for buffer cache size
specification
Cause: User specified one or more of { db_cache_size , db_recycle_cache_size, db_
keep_cache_size, db_nk_cache_size (where n is one of 2,4,8,16,32), db_cache_
advice } AND one or more of { db_block _buffers, buffer_pool_keep , buffer_pool_
recycle }. This is illegal.
Action:   Use EITHER the old (pre-Oracle_8.2) parameters OR the new ones. Don't
specify both. If old size parameters are specified in the parameter file, you may
want to replace them with new parameters since the new parameters can be
modified dynamically and allow you to configure additional caches for additional
block sizes. Cache advisory can only be enabled with the new cache parameters.
