[Q]Solaris Top结果看不明白

yanggq

SunOS 5.8
top的一部分显示如下：

Memory: 5120M real, 2297M free, 1972M swap in use, 4167M swap free

不明白为什么Memory 2297M Free,但是有1972M Swap in Use,请问这个如何调整应用或者相关的参数？
这个系统安装了一套ORACLE，1个INSTANCE
SGA共2G

Hi:

  After solaris 2.x, there is no longer memory swaping rather than paging. So if you see that your swap usage is not zero, do not worry.

Solaris use parameters, such as water marks, to indicate when a infrequent-accessed page should be page out to disk when the high water mark is reached. Please refer to the document on Solaris Tunable Parameters.

From the reading,

Memory: 5120M real, 2297M free, 1972M swap in use, 4167M swap free

You still have a lot of free memory to be used.

Hi:

  The correct reference for the paging is in

http://docs.sun.com/app/docs/doc/806-7009/6jftnqsje?a=view

The parameter is not water marks. Sorry.
