KEEP pool deprecated in 12c

Oracle Database Tips by Donald BurlesonJanuary 25, 2015

The BUFFER_POOL_KEEP and BUFFER_POOL_RECYCLE pool parameters have been deprecated in release 12c.

A deprecated parameter behaves the same way as a regular parameter, except that a warning message is displayed at instance startup if a deprecated parameter is specified in the parameter file. In addition, all deprecated parameters are logged to the alert log at instance startup

The Oracle docs show the query to see deprecated parameters:

"In Oracle Database 12c, some database parameters are deprecated and de-supported, or removed.

To obtain a current list of deprecated parameters, run the following query in SQL*Plus:

SQL> SELECT name from v$parameter 

         WHERE isdeprecated = 'TRUE' ORDER BY name;

The query returns a list of the deprecated parameters as of the date and time that you run it. The following example shows the query results that appear:

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_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"
