To obtain a list of deprecated database parameter in 12c, use the following SQL statement:
To obtain a list of deprecated database parameter in 12c, use the following SQL statement:
SQL> SELECT name from v$parameter WHERE isdeprecated = 'TRUE' ORDER BY name;
Here is the list:
active_instance_count background_dump_dest buffer_pool_keep buffer_pool_recycle commit_write cursor_space_for_time fast_start_io_target global_context_pool_size instance_groups lock_name_space log_archive_local_first log_archive_start max_enabled_roles parallel_automatic_tuning parallel_io_cap_enabled parallel_server parallel_server_instances plsql_v2_compatibility remote_os_authent resource_manager_cpu_allocation sec_case_sensitive_logon serial_reuse sql_trace standby_archive_dest user_dump_dest
I am little bit surprised to see the sec_case_sensitive_logon parameter in the list.
