這次做了一套核心系統的ogg同步，一下是遇到的report報錯，做個記錄
問題一： OGG-01705 Input checkpoint position.. for input trail file..greater than the size of the file
2019-09-10 09:28:08 ERROR OGG-01705 Input checkpoint position 314748185 for input trail file '/oggfs/dirdat/af000068' is greater than the size of the file (31469181
8). Please consult Oracle Knowledge Management Doc ID 1138409.1. for instructions.
報錯已經給出了mos文檔號，直接照這mos操作就可以了
原因很簡單，因爲seq號超過了隊列文件大小，所以ogg找不到這個seq號
我這裏的隊列文件大小是314691818<314748185我輸入的seq號

解決辦法：
start * filterduptransactions
或者是seq輸入有問題
問題二：OGG-01028: Incompatible record (102)
OGG-01028 Incompatible record (102) in /oggfs/dirdat/ac000061, rba 117653457 (getting header).
記錄損壞，也可能是整個隊列文件損壞
使用logdump去定位問題
Logdump 217 >open /oggfs/dirdat/ac000061
Current LogTrail is /oggfs/dirdat/ac000061
Logdump 224 >pos 117653457

--多次next不會調到下一條記錄，說明整個隊列文件損壞
alter replicat1 extseqno 62 extrba nextnumber1--跳過這個記錄
alter replicat1 seqno 63 --跳過整個隊列文件
根據隊列文件生成時間，去源端重傳隊列文件，並在rba事務發生時間之前去啓動replicat並加上handcollision參數
（在有主鍵或者有唯一索引的情況下handcollision也可以保證數據一致性，如果沒有數據無法保證一致）
（其實這個問題相對要複雜一點點，隊列文件損壞需要確認投遞過程中損壞還是抽取損壞，如果是投遞損壞可以重新投遞，如果是抽取損壞需要重新抽取並投遞）
問題三：
OGG-01032:There is a problem in network communication
2019-09-10 11:03:03 ERROR OGG-01032 There is a problem in network communication, a remote file problem, encryption keys for target and source do not match (if using

初看以爲是網絡問題，直接去找網絡工程師，結果非常尷尬
實際上目標端mgr都掛了，端口沒開
