OSW工具-Oracle的OS watcher
Metalink Note:301137.1
OSW 4.0 后变成了： OSWbb 与 OSWbba 的关系。
安装及启动
下载解包以后即可使用：
下面用osw4.0做为例子，4.0以前的版本是一样的
OSW的诊断信息字段含义说明
| 字段 |

| smtx | Number of times a CPU failed to obtain a mutex |
| srw | Number of times a CPU failed to obtain a read/write lock on the first try |
| syscl | Number of system calls |
| usr | Percentage of CPU cycles spent on user processes |

OSW的设置
当OSW安装完毕后，OSW的解压缩脚本里就提供了管理osw的启动和停止的scripts。当第一次运行OSW的时候，系统会自动在osw的目录下创建一个子目录archive，并在archive目录下再创建7个子目录。
[cs1] /oracle/osw> cd archive
[cs1] /oracle/osw/archive> ls -ltr
total 0
drwxr-xr-x 2 oracle dba 256 Jul 13 10:24 oswprvtnet
drwxr-xr-x 2 oracle dba 256 Jul 13 10:24 oswvmstat
drwxr-xr-x 2 oracle dba 256 Jul 13 10:24 oswtop
drwxr-xr-x 2 oracle dba 256 Jul 13 10:24 oswps
drwxr-xr-x 2 oracle dba 256 Jul 13 10:24 oswnetstat
drwxr-xr-x 2 oracle dba 256 Jul 13 10:24 oswmpstat
drwxr-xr-x 2 oracle dba 256 Jul 13 10:24 oswiostat
[cs1] /oracle/osw/archive>
如果要收集private networks 信息，必须要手工创建一个可执行文件在osw目录下，并且命名为private.net。这个文件的设置可以参考osw目录下提供的Exampleprivate.net.这个文件中包含了用来检查RAC private networks 运行traceroute的命令.
比如：
traceroute -r -F node1
traceroute -r -F node2

在生成图形界面的时候报错，注意Timestamp Error报错信息， 产生这个错误的原因就是我的操作系统是中文环境，osw要英文日期格式才可以。
解决办法：
[oracle@TEST archive]$ echo $LANG
zh_CN.UTF-8
[oracle@TEST ~]$ LANG=en
[oracle@TEST ~]$ echo $LANG
en
报错二：
[oracle@TEST oswbb]$ java -jar oswbba.jar -i archive

原因：无法通过X11图形界面显示，因为我用的SecureCRT，没有图形界面，故报错。
解决办法：
如果能访问服务器的图形界面最好，如何条件不允许，可以使用工具Xmanager或者VNC
VNC的安装配置详见：http://blog.csdn.net/langkeziju/article/details/9832879
