同事正常操作，並停止一個ogg進程，數據庫是12c的。ogg當然也是12c的版本。一切都是一個正常的操作，但是出了坑爹的效應，差不多四個人，搞了近3個小時吧。下面我們看看詳細的報錯;

我們report這個進程，得到的報錯是

(227581650643)).
2019-08-13 21:24:07 ERROR OGG-01668 PROCESS ABENDING.
初看是歸檔丟失了，確實是，該庫是一套統計報表庫。OLAP系統，每小時歸檔產生量超級多。所以有腳本定時刪除，每5分鍾刪除一次。
常見的方法，肯定是恢復這個歸檔文件;

但是抱歉，一切都是徒勞，我們的庫太大，而且沒有專用的備份軟件。所以，一直在裸奔狀態。就是說要死大家一起死的那種，自己去想吧;
通過查詢，得到了一個解決方案;
Oracle GoldenGate is reliant on the Oracle Redo Logs and Archive Logs when capturing transactions. Since I do a lot of testing on VMs (limited space) and in the cloud (limited space … don’t want to burn to much $), I often delete my archive logs. Normally this is not a problem; however, every once-in-awhile I delete more archivelogs than I should. This throws the IE into a state where it will not start because of OGG-00868/ORA-01291 – Missing Log Files.
On some level this is to be expected, but when you are using IE you have to remember that the extract is registered with the database. Since I’m using Integrated Extract, we have to reset how the extract is registered with the database. The below steps will show you how this should be done:
Note: Registering/Unregistering process have to be done at the container database (CDB) level.
adminclient> dblogin useridalias domain
adminclient> stop extract <extract_name>
adminclient> unregister extract <extract_name>database
adminclient> register extract <extract_name>database container <container_name>
adminclient> start extract <extract_name>
adminclient> info extract <extract_name>
按照解決方案，總是可以走的那么悠然，我們搞一波;

卡住了，需要刪除該進程，完全沒有按照想象的劇本去流轉啊，坑爹啊!!!!我們這里想想，在看看別的，上一次檢查點進程是4月4日。那么有可能這個進程早就出了問題，只不過今天這個哥們點正，觸發了。應該是12c的未知bug了。
