前几天做oracle到MysqL的数据初始化使用GoldenGate 12.2版本，在源端启动initload进程时报错如下：

2016-06-15 14:20:00 ERROR OGG-01201 Error reported by MGR : Access denied.
2016-06-15 14:20:00 ERROR OGG-01668 PROCESS ABENDING.
看报错是提示被目标端mgr拒绝连接。
查看目标端mgr的report，看到以下内容：
2016-06-15 14:20:00 INFO OGG-00963 Oracle GoldenGate Manager for Oracle,mgr.prm: Command received from EXTRACT on host [106.3.*.*]:46817 (START REPLICAT REPINIT cpu -1 PRI -1 PARAMS ).
2016-06-15 14:20:00 WARNING OGG-00936 Oracle GoldenGate Manager for Oracle,mgr.prm: Access denied (request from 106.3.*.*,rule #0).
可以看到是目标端mgr主动拒绝了源端extract启动replicat进程repinit。
后进过查询资料，这是由于GoldenGate 12.2的新特性导致的，要想可以通过远程启动目标端的replicat进程，需要在mgr中增加参数如下：
ACCESSRULE,PROG *,IPADDR 106.3.*.*,ALLOW
之后再从源端启动initload进程，这次成功启动，进程状态正常。
