Oracle所有诊断事件列表events是怎样的，很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。

Oracle所有诊断事件列表events

通过如下的脚本可以获取所有的诊断事件列表：

在UNIX系统下message文件在底下目录$ORACLE_HOME/rdbms/mesg/oraus.msg
在NT系统下message文件在底下目录$ORACLE_HOME/rdbms/mesg/oraus.msg
oraus.msg文件属于文本文件，可以直接打开查看。

诊断事件可以像普通的ORA错误一样采用oerr命令来查询，如下所示：

event="10248 trace name context forever, level 10"
event="10249 trace name context forever, level 10"

另一种方法是在会话过程中使用alter session set events命令，只对当前会话有影响。设置格式如下：

alter session|system set events '[eventnumber|immediate] trace name eventname [forever] [, level levelnumber] : .......'

通过:符号，可以连续设置多个事件，也可以通过连续使用alter session set events 来设置多个事件。

SQL> show parameter event

------------------------------------ ----------- ------------------------------
SQL> alter system set event='10046 trace name context forever,level 12';
*
ORA-02095: specified initialization parameter cannot be modified

System altered.

Database closed.
ORACLE instance shut down.
ORA-32004: obsolete and/or deprecated parameter(s) specified

Total System Global Area 1157627904 bytes
Variable Size 402654536 bytes
Redo Buffers 31457280 bytes
Database opened.

NAME TYPE VALUE
event string 10046 trace name context forev
SQL>

System altered.

System altered.

SQL> ALTER system SET event='1461 trace name errorstack level 3';
*
ORA-02095: specified initialization parameter cannot be modified
SQL> ALTER system SET event='1461 trace name errorstack level 3' scope=spfile;
验证是否已成功更改：
File created.
[oracle@rac01 ~]$ grep event 1.ora
这种方法的话，需要重启DB。下面Rollback这个参数更改
System altered.
File created.
[oracle@rac01 ~]$ grep event 2.ora
2. alter system set events：此方法对memory生效，无法对spfile生效

SQL> !
[oracle@rac01 ~]$ tail -n1 /oracle/admin/strm1/bdump/alert_strm1.log
这个参数更改没有反应到spfile中
File created.
[oracle@rac01 ~]$ grep event 3.ora
其实这里的1461是个BUG 6085625，Metalink上可以参照NOTE: 461911.1
另外需要注意的是，RAC环境中用方法2动态设置event的话需要在所有instance设置。不过理解了上面的区别的话这个也就很容易明白了。

四. 示例

4.1 查看当前trc 文件
select
　　u_dump.value || '/' ||
　　db_name.value || '_ora_' ||
　　v$process.spid ||
　　nvl2(v$process.traceid, '_' || v$process.traceid, null )
　　|| '.trc' "Trace File"
from
v$parameter u_dump
cross join v$parameter db_name
cross join v$process
join v$session
on v$process.addr = v$session.paddr
where
　　u_dump.name = 'user_dump_dest' and
　　db_name.name = 'db_name' and
　　v$session.audsid=sys_context('userenv','sessionid');
eg：
/oracle/product/10.2.0/admin/dw/udump\dw_ora_389530.trc

4.2 执行event

alter session set events '10046 trace name context forever, level 1';
select count(1) from all_tables;
alter session set events '10046 trace name context off' ;

4.3 在查看dw_ora_389530.trc

$dw_ora_389530.trc

5614566		如果数据库版本为Oracle 10g以前，那么只能清空整个Shared Pool，命令为："ALTER SYSTEM FLUSH SHARED_POOL;"。在Oracle 10g中提供了一个包DBMS_SHARED_POOL，该包可以实现该功能。若该包没有安装，则可以通过$ORACLE_HOME/rdbms/admin/dbmspool.sql进行安装。在Oracle 10.2.0.4中有BUG（MOS为：751876.1），需要通过设置事件来规避该问题，命令为：" ALTER SESSION SET EVENTS '5614566 TRACE NAME CONTEXT FOREVER';" 使用这种方法，就可以精确的将一个SQL从共享池中删除，从而使得Oracle为这个SQL重新生成执行计划。这种方法只针对单个SQL语句，使得解决问题的同时不会造成任何的误伤。 SYS@lhrdb> SELECT ADDRESS,HASH_VALUE FROM V$SQLAREA WHERE ROWNUM<=1; ADDRESS HASH_VALUE ---------------- ---------- 0000000092D263D0 3231842444 SYS@lhrdb> EXEC DBMS_SHARED_POOL.PURGE('0000000092D263D0,3231842444','C'); PL/SQL procedure successfull	ALTER SESSION SET EVENTS '5614566 TRACE NAME CONTEXT FOREVER';
