ORA-01552 cannot use system rollback segment for non-system tablespace

创建表的时候报

ORA-01552 cannot use system rollback segment for non-system tablespace

SQL> CREATE TABLE DEPT
  2         (DEPTNO NUMBER(2) CONSTRAINT PK_DEPT PRIMARY KEY,
  3          DNAME VARCHAR2(14) ,
  4          LOC VARCHAR2(13) ) ;
CREATE TABLE DEPT
*
ERROR at line 1:
ORA-01552: cannot use system rollback segment for non-system tablespace 'USERS'

 

解决办法：

SQL> show parameter undo

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
undo_management                      string      MANUAL
undo_retention                       integer     900
undo_tablespace                      string      UNDOTBS2

SQL> alter system set undo_tablespace='undotbs3' scope=spfile;

System altered.

 

SQL> alter system set undo_management=auto scope=spfile;

System altered.

SQL> show parameter undo

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
undo_management                      string      AUTO
undo_retention                       integer     900
undo_tablespace                      string      undotbs3

重新测试刚才出错的语句

SQL> conn scott/tiger
Connected.
SQL>
SQL>
SQL> CREATE TABLE DEPT
  2         (DEPTNO NUMBER(2) CONSTRAINT PK_DEPT PRIMARY KEY,
  3          DNAME VARCHAR2(14) ,
  4          LOC VARCHAR2(13) ) ;

Table created.

我的由于没有undotbs2，并且undo_management为手动模式，所以必须切换
