Name
SHARED_POOL_RESERVED_SIZE
Synopsis
Value: SHARED_POOL_RESERVED_MIN_ALLOC - SHARED_POOL_SIZE / 2
Default: SHARED_POOL_SIZE * 05
Specifies the shared pool space that is reserved for large contiguous requests for shared pool memory. With the SHARED_POOL_RESERVED_MIN_ALLOC parameter, this parameter can be used to avoid performance degradation in the shared pool from situations in which pool fragmentation forces Oracle to search for and free chunks of unused pool to satisfy the current request. If SHARED_POOL_RESERVED_SIZE exceeds 1/2 SHARED_POOL_SIZE, Oracle signals an error. In general, you should set SHARED_POOL_RESERVED_SIZE to 10% of SHARED_POOL_SIZE. Can be specified as a numeric value or a number followed by K (1000) or M (1,000,000).
