1,数据库的版本

www.htz.pw > select * from v$version;

 

BANNER

--------------------------------------------------------------------------------

Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

PL/SQL Release 11.2.0.4.0 - Production

CORE   11.2.0.4.0     Production

TNS for Linux: Version 11.2.0.4.0 - Production

NLSRTL Version 11.2.0.4.0 - Production

2,在spfile中修改event参数

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

 

System altered.

 

www.htz.pw > startup force;

 

 

www.htz.pw > @dump_event.sql

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

"session - Dump session group's event settings                             "

"process - Dump process group's event settings                             "

"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='*';

 

其实我们还可以使用下面的方法

这里需要注意的是:level 512后面接的:没有','

 

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

 

System altered.

 

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

"session - Dump session group's event settings                             "

"process - Dump process group's event settings                             "

"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

3,在init中修改event参数

方法1

www.htz.pw > !grep "event" /tmp/123.txt

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

方法2

www.htz.pw > !grep "event" /tmp/123.txt

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

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

方法3:

www.htz.pw > !grep -A1 "event" /tmp/123.txt

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

10015 trace name context forever,level 1' 

4,清空event的方法

如果使用init参数文件,直接删除event参数,如果使用spfile文件

www.htz.pw > @dump_event.sql

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

"session - Dump session group's event settings                             "

"process - Dump process group's event settings                             "

"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

www.htz.pw > alter system set event='' scope=spfile ;

其实这里我们还可以使用reset event scope=spfile sid='*'来操作

System altered.

 

www.htz.pw > startup force;

ORACLE instance started.
