今天无缘无故的outln不见了，后台alter日志也没有删除的信息。重新创建也创建不上

create user outln identified by outln

*

ERROR at line 1:

ORA-00604: error occurred at recursive SQL level 1

ORA-18008: cannot find OUTLN schema

很是郁闷，不见了居然还不让创建。

只能通过后台的dump文件来查看原因了

sqlplus / as sysdba

alter session set events '18008 trace name errorstack level 3';

alter session set events '10046 trace name context forever, level 12';

create user outln identified by outln;

通过跟踪后台日志查看。

知道是这个trigger的问题：MDSYS.SDO_ST_SYN_CREATE

alter trigger MDSYS.SDO_ST_SYN_CREATE disable;

create user outln identified by outln;

alter trigger MDSYS.SDO_ST_SYN_CREATE enable;

这个以后就不会出现ORA-18008: cannot find OUTLN schema这个问题了。

附上：OUTLN用户的创建语句
