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。
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
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eventalter 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

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。
