1、查询shared_pool参数值在RAC环境下不同
select inst_id,COMPONENT, CURRENT_SIZE
from gV$SGA_DYNAMIC_COMPONENTS
where COMPONENT like ‘shared pool’;

select inst_id,pool,sum(bytes) BYTES
from gv$sgastat
where pool is not null
group by inst_id,pool;

2、由于shared_pool值不同导致了
shared_pool_reserved_size的值在不同实例不同
shared_pool值如何确定，在11G中人为修改成固定值是否合适？
