V$SHARED_POOL_ADVICE

V$SHARED_POOL_ADVICE displays information about estimated parse time savings in the shared pool for different sizes. The sizes range from 50% to 200% of the current shared pool size, in equal intervals. The value of the interval depends on the current size of the shared pool.

Column Datatype Description

SHARED_POOL_SIZE_FOR_ESTIMATE

NUMBER

Shared pool size for the estimate (in megabytes)

SHARED_POOL_SIZE_FACTOR

NUMBER

Size factor with respect to the current shared pool size

ESTD_LC_SIZE

NUMBER

Estimated memory in use by the library cache (in megabytes)

ESTD_LC_MEMORY_OBJECTS

NUMBER

Estimated number of library cache memory objects in the shared pool of the specified size

ESTD_LC_TIME_SAVED

NUMBER

Estimated elapsed parse time saved (in seconds), owing to library cache memory objects being found in a shared pool of the specified size. This is the time that would have been spent in reloading the required objects in the shared pool had they been aged out due to insufficient amount of available free memory.

ESTD_LC_TIME_SAVED_FACTOR

NUMBER

Estimated parse time saved factor with respect to the current shared pool size

ESTD_LC_MEMORY_OBJECT_HITS

NUMBER

Estimated number of times a library cache memory object was found in a shared pool of the specified size
