oracle普通表转分区表（在线重定义方式）
1.1.TAB_TAOBAO_BILL
1.1.1检查下这张表是否可以在线重定义，无报错表示可以，报错会给出错误信息：
exec dbms_redefinition.can_redef_table('ycheng', 'P_TAB_TAOBAO_BILL');
1.1.2.expdp导出表进行备份（这里的DATA_PUMP_1目录是/data1/dpdump）
expdp \'\/ as sysdba\' directory=DATA_PUMP_1 tables=TAB_TAOBAO_BILL dumpfile=ycheng_TAB_TAOBAO_BILL0914.dmp logfile=ycheng_TAB_TAOBAO_BILL0914.log parallel=2;
1.1.3检查TAB_GS_BAG表使用的表空间使用率（这里检查表空间是否充裕，如果表空间不足，执行1.1.4，增加表空间）

1.5启动在线重定义：
exec dbms_redefinition.start_redef_table('ycheng', 'TAB_TAOBAO_BILL', 'P_TAB_TAOBAO_BILL');
1.6.查看量表数据是否一致

select count(1) from YCHENG.P_TAB_TAOBAO_BILL;
1.7.使用dbms_redefinition包的sync_interim_table模块刷新数据后，中间表也可以看到数据更改（这里，当原表数据发生改变时，可用如下刷新同步数据）
--管理员权限执行sql命令行执行,同步两边数据
