ORACLE 配置event参数

下面测试来至于11G

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.   Total System Global Area  379965440 bytes Fixed Size                  2253464 bytes Variable Size             171969896 bytes Database Buffers          201326592 bytes Redo Buffers                4415488 bytes Database mounted.
