我也见过这种情况，并且我在几台机器上测试过，在刚启动oracle的时候，内存剩下一半，
一段时间以后，即使oracle的用户会话进程终止，linux系统好象也不会释放内存一样，用top,free或类似的工具查看内存，会看到剩下的内存没有多少了,不知道是不是linux系统的原因

还有
24547 oracle 15 0 1676m 461m 457m S 26 5.7 0:45.51 oracle
24193 oracle 16 0 1676m 821m 817m S 2 10.1 3:53.42 oracle
这两个进程在干什么.是什么进程.

数据库系统内存占用到7，80％是正常的，我用AIX，IBM的人说内存100％也可以是正常的，关系到他内存释放机制，只要swap 没怎么被用就证明内存一直够的。
