Jagjeet Singh为我们提供了这样一个sqlplus下的RAC dashboard，实时的性能工具，看上去和top或者nmon命令的界面很相似，借助于这个工具我们将可以实时监控RAC的性能指标而不依赖于图形界面。

点击这里下载Jagjeet Singh的sqlplus dashboard for rac工具。

具体的安装方法如下：

解压zip包

[oracle@vrh1 ~]$ unzip Pck.zip
Archive:  Pck.zip
creating: Pck/
inflating: Pck/1_grants.sql
inflating: Pck/2_Types.sql
inflating: Pck/3_pkg.sql
inflating: Pck/drop.sql
inflating: Pck/howtoinstall.sql
inflating: Pck/outputexplained.pdf
inflating: Pck/sampleoutput.png

[oracle@vrh1 ~]$ cd Pck

[oracle@vrh1 Pck]$ sqlplus  / as sysdba

若想删除该工具吗，卸载的方法

SQL> connect maclean/maclean
SQL> start drop.sql

具体使用的方法如下：

SQL>set lines 190 pages 0 arraysize 50
SQL>select * from table(jss.gtop(50,10)) ;

50代表 arraysize 一般不用修改
10代表 10s采样一次，采样间隔

示例输出：





这很酷，仿佛文字版的spotlight FOR RAC
