Oracle运行一会自动停止，日志报错："Instance terminated by PMON, pid = 6072"

解决方法：

SQL> create undo tablespace tbs_undo datafile 'd:\oracle\product\10.2.0\oradata\orcl\undotbs02.dbf' size 500M ;
Tablespace created.
SQL> alter system set undo_tablespace='tbs_undo' scope=both;
System altered.
SQL> show parameter undo
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
