OSW簡介 OSW是Oracle提供的一個監(jiān)控操作系統(tǒng)的工具包，主要用于監(jiān)視系統(tǒng)的狀態(tài)，包括cpu,內(nèi)存，io，網(wǎng)絡等，可以運行于linux和windows，這個工具包可以從Metalink下載。

Metalink Note:301137.1

?

在OSW 4.0 之前是：OSWatcher 和 OSWg的關(guān)系。

OSW 4.0 后變成了： OSWbb 與 OSWbba 的關(guān)系。

OSW的設置

　

當OSW安裝完畢后，OSW的解壓縮腳本里就提供了管理osw的啟動和停止的scripts。當?shù)谝淮芜\行OSW的時候，系統(tǒng)會自動在osw的目錄下創(chuàng)建一個子目錄archive，并在archive目錄下再創(chuàng)建7個子目錄。

[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，必須要手工創(chuàng)建一個可執(zhí)行文件在osw目錄下，并且命名為private.net。這個文件的設置可以參考osw目錄下提供的Exampleprivate.net.這個文件中包含了用來檢查RAC private networks 運行traceroute的命令.

比如：

traceroute -r -F node1
traceroute -r -F node2

在生成圖形界面的時候報錯，注意Timestamp Error報錯信息， 產(chǎn)生這個錯誤的原因就是我的操作系統(tǒng)是中文環(huán)境，osw要英文日期格式才可以。

解決辦法：

[oracle@TEST archive]$ echo $LANG?
zh_CN.UTF-8

[oracle@TEST ~]$ LANG=en
[oracle@TEST ~]$ echo $LANG
en

原因：無法通過X11圖形界面顯示，因為我用的SecureCRT，沒有圖形界面，故報錯。

解決辦法：

如果能訪問服務器的圖形界面最好，如何條件不允許，可以使用工具Xmanager或者VNC

?VNC的安裝配置詳見：http://blog.csdn.net/langkeziju/article/details/9832879
