内存监控使用53g

而服务器加上swap才20G

而根据下面sql查询总的内存也是
select
(select sum(cast(n_pages as bigint)* page_size)/1024/1024 from v$bufferpool)||'MB' as BUFFER_SIZE,
( select sum(cast(total_size as bigint))/1024/1024 from v$mem_pool)||'MB' as mem_pool,
(select sum(cast(n_pages as bigint) * page_size)/1024/1024 from v$bufferpool)+(select sum(cast(total_size as bigint))/1024/1024 from v$mem_pool)||'MB' as TOTAL_SIZE
From dual;
