嘗試無引數啟動資料庫時報錯ORA-304錯誤

在一個已經配置了RAC + ASM環境的資料庫中，嘗試利用RMAN的無引數啟動，出現了ORA-304錯誤。

 

 

錯誤資訊如下：

bash-3.00$ rman target /

懷疑是當前執行的另外一個資料庫的RAC例項導致了Oracle的啟動錯誤，於是嘗試關閉另外一個資料庫的例項：

bash-3.00$ sqlplus "sys/test@ractest1 as sysdba"

關閉資料庫例項後，問題依舊。莫非ASM例項對當前的啟動也有影響。不過由於下面的操作會嘗試使用ASM例項上的內容，因此不能關閉ASM。

嘗試編輯一個最簡單的引數問題，看能否啟動例項：

bash-3.00$ vi initrac11g1.ora
"initrac11g1.ora" [New file]
db_name=rac11gs

下面把剛才關閉的例項重新啟動，看這個例項是否會產生影響：

bash-3.00$ bash
bash-3.00$ export ORACLE_SID=ractest1
bash-3.00$ sqlplus "/ as sysdba"

檢查了一下metalink，也沒有發現和當前問題比較吻合的情況，不過懷疑問題和Bug No. 5557910比較類似，可能是Oracle的bug造成的。
