String 

SHARED_POOL_RESERVED_SIZE = integer [K | M] 

Static 

5% of the value of SHARED_POOL_SIZE 

Minimum: value of SHARED_POOL_RESERVED_MIN_ALLOC

Maximum: one half of the value of SHARED_POOL_SIZE (in bytes) 

SHARED_POOL_RESERVED_SIZE specifies in bytes the shared pool space that is reserved for large contiguous requests for shared pool memory. You can use this parameter to avoid performance degradation in the shared pool in situations where pool fragmentation forces Oracle to search for and free chunks of unused pool to satisfy the current request.
