Collects information about database pages to be used for cache warming the next time the database is started.

Syntax

{ dbsrv11 | dbeng11 } -cc { + | - } ...

Applies to

All operating systems and database servers.

Remarks

By default, page collection is turned on. When collection is turned on, the database server keeps track of each database page that is requested. Collection stops when the maximum number of pages has been collected, the database is shut down, or the collection rate falls below the minimum value. Note that you cannot configure the maximum number of pages collected or specify the value for the collection rate (the value is based on cache size and database size). Once collection stops, information about the requested pages is recorded in the database so those pages can be used to warm the cache the next time the database is started with the -cr option. Collection of referenced pages is turned on by default.
