Range of values
0 to operating system-dependent
You must either set this parameter to 0 on all instances to disable the result cache, or use a nonzero value on all instances. Disabling the result cache on some instances may lead to incorrect results.
RESULT_CACHE_MAX_SIZE specifies the maximum amount of SGA memory (in bytes) that can be used by the Result Cache. Values of this parameter greater than 0 are rounded up to the next multiple of 32 KB. If the value of this parameter is 0, then the feature is disabled.
