Poster: ORA-01458: invalid length inside variable character string. 处理一例

产品环境，shareplex复制报错，查看log:

查看两边的表结构，一致。

处理方法：

1. source端，查询AAAAAAA的object_id，比如：111111

2. post端，

set param sp_opo_disable_object_num 111111
stop post
start post

===正常之后

reset param SP_OPO_DISABLE_OBJECT_NUM
stop post
start post

丢的数据，到log目录下面能找到。里面有详细信息。
