OGG-DDL同步报错OGG-00516 ORA-12991: column is referenced in a multi-column constraint]

一、报错内容

ERROR   OGG-00516  Fatal error executing DDL replication: error [Error code [12991], 
ORA-12991: column is referenced in a multi-column constraint], due to explicit ABEND error handling and filter
 [include all (default)]

二、问题分析

SYS@t1gbk>SELECT DDLTYPE,METADATA_TEXT,OPTIME from ogg1.GGS_DDL_HIST where objectowner='TEST2' AND OBJECTNAME='TEST1' ORDER BY 3;
ALTER
,G1='alter table test1 drop column cc ',

2个字段，删除一个字段正常没毛病！  但是目标端复制进程删除报错？？？ 谁还引用这个字段？？？

SQL> select * from DBA_CONSTRAINTS where table_name='TEST1';

no rows selected

约束排除！  最后剩下，本次测试环境是双向同步，这个表在目标端，作为反向OGG源端存在抽取进程！

> DELETE TRANDATA TEST2.TEST1   在重启进程就可以了！ 

！！！注意双向同步是，源端进行删除字段操作，可能无法执行！
