前幾天做oracle到mysql的資料初始化使用GoldenGate 12.2版本，在源端啟動initload程序時報錯如下：

2016-06-15 14:20:00  ERROR   OGG-01668  PROCESS ABENDING.

看報錯是提示被目標端mgr拒絕連線。

檢視目標端mgr的report，看到以下內容：

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).

可以看到是目標端mgr主動拒絕了源端extract啟動replicat程序repinit。

後進過查詢資料，這是由於GoldenGate 12.2的新特性導致的，要想可以通過遠端啟動目標端的replicat程序，需要在mgr中增加引數如下：

ACCESSRULE, PROG *, IPADDR 106.3.*.*, ALLOW

之後再從源端啟動initload程序，這次成功啟動，程序狀態正常。
