Name

DB_CACHE_ADVICE

Synopsis

Value: ON | OFF | READY

Default: OFF

Dynamic: ALTER SYSTEM

Specifies how statistics gathering used for predicting database performance with different cache sizes will be performed. If this parameter is set to OFF and then changed to ON using the ALTER SYSTEM statement, an error is likely to occur, because memory will not be allocated. Use the READY setting to allow this parameter to be changed to ON at a later time. New with Oracle9i.

Keywords

ON

Cache advisory is turned on and statistics are gathered.

OFF

Cache advisory is turned off, and no memory is allocated for gathering of statistics.

READY

Cache advisory is turned off, but memory is allocated for statistics.
