一、复制进程启动报错
如果有遇到相同报错的小伙伴，注意，复制进程使用抽取模式进行集成注册成功后，启动之后报错！！！ 直接删除重建就好了！
但是各种搜索资料没有找到匹配的，不细心害死人，还有一个问题，报错根本没有往模式错误方向走！
这个文档没什么技术，主要是帮助后续也是语法错误小伙伴快速定位问题！

然后复制进程报错

二.问题分析
这里走了严重的弯路，没有仔细阅读语法，反而根据报错进行分析！！！
模式都不对，因此取消集成注册提示无法进行操作
unregister REPLICAT REP_A1 database
使用这个命令直接删除了非常非常多的级联对象，慎重操作！ exec dbms_streams_adm.remove_queue(queue_name=>'OGG$REP_A1',cascade=>true,drop_unused_queue_table=>true); select OWNER,OBJECT_NAME,OBJECT_TYPE from dba_objects where upper(object_name) like '%REP_A1%'; OWNER OBJECT_NAME OBJECT_TYPE -------------------- ------------------------------ ------------------- SYS OGG$CAP_REP_A1 CAPTURE SYS OGG$REP_A1 APPLY OGG2 OGG$Q_TAB_REP_A1 TABLE OGG2 AQ$_OGG$Q_TAB_REP_A1_S TABLE OGG2 AQ$_OGG$Q_TAB_REP_A1_V EVALUATION CONTEXT OGG2 AQ$_OGG$Q_TAB_REP_A1_T TABLE OGG2 AQ$OGG$Q_TAB_REP_A1_S VIEW OGG2 AQ$_OGG$Q_TAB_REP_A1_N SEQUENCE OGG2 AQ$_OGG$Q_TAB_REP_A1_H TABLE OGG2 AQ$_OGG$Q_TAB_REP_A1_L TABLE OGG2 AQ$_OGG$Q_TAB_REP_A1_G TABLE OGG2 AQ$_OGG$Q_TAB_REP_A1_I TABLE OGG2 AQ$_OGG$Q_TAB_REP_A1_C TABLE OGG2 AQ$_OGG$Q_TAB_REP_A1_Y INDEX OGG2 AQ$_OGG$Q_TAB_REP_A1_E QUEUE OGG2 AQ$_OGG$Q_TAB_REP_A1_F VIEW OGG2 AQ$OGG$Q_TAB_REP_A1 VIEW OGG2 OGG$Q_REP_A1_R RULE SET OGG2 OGG$Q_REP_A1_N RULE SET OGG2 AQ$OGG$Q_TAB_REP_A1_R VIEW OGG2 OGG$Q_REP_A1 QUEUE OGG2 AQ$_OGG$Q_TAB_REP_A1_P TABLE OGG2 AQ$_OGG$Q_TAB_REP_A1_D TABLE 23 rows selected.

根据上述操作，无法解决这个问题，使用如下，完整清理了一波，重点是使用抽取集成模式取消注册，重新添加OGG进程就可以了。
