ORA-00704與bootstrap錯誤

　　今天有一個客戶在升級數據庫到g之後遇到了如下錯誤

　　  ORA: bootstrap process failure
ORA: error occurred at recursive SQL level
ORA: fetched column value was truncated
Error happened during db open shutting down database
USER: terminating instance due to error
Instance terminated by USER pid =
ORA signalled during: ALTER DATABASE OPEN

　　一般來說見到bootstrap錯誤都是很嚴重的故障bootstrap過程失敗數據庫肯定就無法打開很多時候bootstrap$表損壞也會導致bootstrap失敗

　　以上一系列錯誤說明在升級的過程中出現問題升級是不完全的從而導致數據庫無法bootstrap可以嘗試從備份中恢復數據庫再次進行升級
