--//nattch表示连接使用共享内存段的进程数.正好151可以与smem显示的PIDS对上.不再生产系统折腾,换测试机器测试.

--//设置pre_page_sga=true,表示启动数据库全部加载整个SGA到内存.
--//633339904/1024/1024 = 604M
--//其实这样后面的PSS内存总和基本表示这个实例使用的内存量.

http://docs.oracle.com/cd/E11882_01/server.112/e40402/initparams201.htm#REFRN10174
PRE_PAGE_SGA determines whether Oracle reads the entire SGA into memory at instance startup. Operating system page table
entries are then prebuilt for each page of the SGA. This setting can increase the amount of time necessary for instance
startup, but it is likely to decrease the amount of time necessary for Oracle to reach its full performance capacity
after startup.
