通过查询metalink给出了以下解决方案，目前系统交换分区跟内存一样都是8G，就没有扩充；最后通过在不过度影响数据库性能的方式减小SGA给系统保留更多的内存。有点郁闷的是据说HP UNIX 11.31很吃内存，但是也不能保留3个多G都不够用吧。

Solution

Please ask your SA to resize the Swap area following the next formula:

If RAM = 1024MB to 2048Mb 
then 1.5 times RAM 
elseif RAM > 2048MB and then match RAM 
else RAM > 8192MB 
then .75 times RAM
