在进行在线重定义的时候总是出现这个错误
SQL>  EXEC DBMS_REDEFINITION.START_REDEF_TABLE(USER, 'T1', 'T1_NEW',  DBMS_REDEFINITION.CONS_USE_PK);
BEGIN DBMS_REDEFINITION.START_REDEF_TABLE(USER, 'T1', 'T1_NEW',  DBMS_REDEFINITION.CONS_USE_PK); END;

ERROR at line 1:

ORA-06512: at "SYS.DBMS_REDEFINITION", line 52
ORA-06512: at "SYS.DBMS_REDEFINITION", line 1646

表结构如下：
SQL> desc t1;

----------------------------------------- -------- ----------------------------

OUTER_ID                                        VARCHAR2(100)

SQL> desc t1_new;

OUTER_ID                                        VARCHAR2(100)
其中t1_new进行了分区
，请教一下这是啥原因啊

ODM FINDING:

[oracle@vrh8 ~]$ oerr ora 42016
42016, 0000, "shape of interim table does not match specified column mapping"
// *Cause:  The number of columns, or the type or the length semantics of a
//       column, in the interim table did not match the specified
//       column mapping.
// *Action: Ensure that the interim table matches the column mapping by
//       either modifying the column mapping string or altering the
//       interim table's column definition(s).

DBMS_REDEFINITION.START_REDEF_TABLE 的默认语法：

  -- NAME:    start_redef_table - start the online re-organization
  -- INPUTS: uname       - schema name
  --          orig_table - name of table to be re-organized
  --          int_table - name of interim table
  --          col_mapping  - select list col mapping
  --          options_flag - flag indicating user options to use
  --          orderby_cols - comma separated list of order by columns
  --                         followed by the optional ascending/descending
  --                         keyword
  --          part_name - name of the partition to be redefined
  PROCEDURE start_redef_table(uname       IN VARCHAR2,
                           orig_table IN VARCHAR2,
                           int_table IN VARCHAR2,
                           col_mapping  IN VARCHAR2 := NULL,
                           options_flag IN BINARY_INTEGER := 1,
                           orderby_cols IN VARCHAR2 := NULL,
                           part_name IN VARCHAR2 := NULL);

你的参数用错了,

SQL> EXEC DBMS_REDEFINITION.START_REDEF_TABLE(USER, 'T1', 'T1_NEW',  DBMS_REDEFINITION.CONS_USE_PK);
BEGIN DBMS_REDEFINITION.START_REDEF_TABLE(USER, 'T1', 'T1_NEW',  DBMS_REDEFINITION.CONS_USE_PK); END;
*
ERROR at line 1:
ORA-42016: shape of interim table does not match specified column mapping
ORA-06512: at "SYS.DBMS_REDEFINITION", line 52
ORA-06512: at "SYS.DBMS_REDEFINITION", line 1646
ORA-06512: at line 1

SQL> EXEC DBMS_REDEFINITION.START_REDEF_TABLE(UNAME=>USER,ORIG_TABLE=>'T1',INT_TABLE=>'T1_NEW',OPTIONS_FLAG=>DBMS_REDEFINITION.CONS_USE_PK);
PL/SQL procedure successfully completed.

PROCEDURE START_REDEF_TABLE
Argument Name                Type                   In/Out Default?
------------------------------ ----------------------- ------ --------
UNAME                         VARCHAR2             IN
ORIG_TABLE                   VARCHAR2             IN
INT_TABLE                   VARCHAR2             IN
COL_MAPPING                   VARCHAR2             IN    DEFAULT
OPTIONS_FLAG                BINARY_INTEGER       IN    DEFAULT
ORDERBY_COLS                VARCHAR2             IN    DEFAULT
PART_NAME                   VARCHAR2             IN    DEFAULT

默认情况下第4个参数是 COL_MAPPING, 所以你原来的写法会报错。
需要指定下参数就可以了。
