Non-SYSDBA user can change FW mode of database. [CORE1972] #2410
Commented by: @AlexPeshkoff
Except force write setting, access is also limited (admin and DBO only) to the following list of dpb options: dpb_set_db_readonly, dpb_set_db_sql_dialect, dpb_sweep_interval and dpb_no_reserve. Use of dpb_set_page_buffers differs in classic and super servers. In case of SS it's completely disabled for non-admin connections. In case of CS one can set size of buffers per connection, but settings in database remain not modified.
