"system  - Dump system group's event settings(Ie the instance wide events)  "

"***************************************************************************"

Statement processed.

Enter value for input: system

10015 trace name context forever, level 1

10235 trace name context forever,level 512

清空event的值

ALTER SYSTEM RESET EVENT SCOPE=SPFILE SID='*';

其實我們還可以使用下面的方法

這裡需要注意的是：level 512後面接的：沒有','

> alter system set event='10235 trace name context forever,level 512:10015 trace name context forever,level 1' scope=spfile;

System altered.

"system  - Dump system group's event settings(Ie the instance wide events)  "

"***************************************************************************"

Statement processed.

Enter value for input: system

10235 trace name context forever,level 512

10015 trace name context forever,level 1

方法1

> !grep "event" /tmp/123.txt

*.event='10235 trace name context forever,level 512:10015 trace name context forever,level 1'

方法2

> !grep "event" /tmp/123.txt

*.event='10235 trace name context forever,level 512'

*.event='10015 trace name context forever,level 1'

方法3：

>  !grep -A1 "event" /tmp/123.txt

*.event='10235 trace name context forever,level 512:\

10015 trace name context forever,level 1' 

> @dump_event.sql

> alter system set event='' scope=spfile ;

其實這裡我們還可以使用reset event scope=spfile sid='*'來操作
