從此SQLPLUS有了Top命令

August 8, 2012 By Maclean Liu 3 Comments

Jagjeet Singh為我們提供了這樣一個sqlplus下的RAC dashboard，實時的效能工具，看上去和top或者nmon命令的介面很相似，藉助於這個工具我們將可以實時監控RAC的效能指標而不依賴於圖形介面。

點選這裡下載Jagjeet Singh的sqlplus dashboard for rac工具。

具體的安裝方法如下：

解壓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

SQL*Plus: Release 11.2.0.3.0 Production on Wed Aug 8 02:08:49 2012

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

Data Mining and Real Application Testing options

1.  執行授權檔案1_grants.sql        

SQL> start 1_grants.sql
Enter value for _usr: maclean

需要指定安裝在哪個schema下

2. 登入上面指定的schema，並執行 2_Types.sql 建立type

SQL> conn maclean/maclean
Connected.
SQL> 
SQL> 
SQL> start 2_Types.sql

Type created.

3. 執行3_pkg.sql 建立包體

SQL> start 3_pkg.sql

Package created.

No errors.

Package body created.

 若想刪除該工具嗎，解除安裝的方法 

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

具體使用的方法如下：

 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取樣一次，取樣間隔

示例輸出：

這很酷，彷彿文字版的spotlight FOR RAC
