文档课题：搭建ogg双向复制时，oracle 19.16向oracle 10.2.0.4 ogg复制时报警OGG-01389、OGG-02246处理记录.
源 端：IP 192.168.133.103 数据库oracle 11.2.0.4 64位，实例名：orcl 主机名：leo-10g-ogg
目 标 端：IP 192.168.133.109 数据库oracle 19.16.0.0 64位，实例名：simdb 主机名：leo-19c-ogg
ogg 软件：
源 端：fbo_ggs_Linux_x64_ora10g_64bit.tar
目 标 端：191004_fbo_ggs_Linux_x64_shiphome.zip

--ogg双向复制搭建成功后，ddl测试如下：

说明：可以看到simdb端修改字段长度后，在orcl端并没有相应的更新.
2、异常分析

--主要报错依然是“File header failed to parse tokens”.
3、解决过程
经查询资料，此为ogg版本不同造成，修改simdb端抓取、投递进程参数.
--停止两端进程.

--修改simdb端抓取、投递进程
--注意：虽然此处查的orcl端ogg版本为11.1，但添加时需要写12.2，测试过添加11.1后，启动exta进程告警如下：
