一般情况下,诊断事件可以在Session级设置,也可以在系统级设置,如果你要诊断全局错误,则最好在系统级设置较为合适,下面是一个测试实例:
SQL> alter system set event=’984 trace name ERRORSTACK level 10’ scope=spfile; System altered. SQL> startup force; ORACLE instance started. Total System Global Area 101782828 bytes Fixed Size 451884 bytes Variable Size 37748736 bytes Database Buffers 62914560 bytes Redo Buffers 667648 bytes Database mounted. Database opened. SQL> create table t (name varchar2(10),id number); Table created. SQL> insert into t values(a,1); insert into t values(a,1) * ERROR at line 1: ORA-00984: column not allowed here SQL> |
请注意,此刻984错误将会被跟踪,记录到跟踪文件中。注意检查udump目录,找到trace文件:
注释:此跟踪文件可以定位和诊断错误。
