Oracle 入門之Oracle啟動報錯“ORA-03113”

發(fā)布時間: 2012/9/21 16:52:35

早上連接Oracle,發(fā)現(xiàn)oracle無法正常工作，無法shutdown immediate方式關(guān)閉，shutdown abort方式關(guān)閉之后再啟動，出現(xiàn)錯誤提示“ORA-03113 end-of-file on communication channel”

分析alter日志信息如下：
Errors in file /u01/diag/rdbms/online/online/trace/online_ora_1544.trc: -

ORA-19815: 警告: db_recovery_file_dest_size 字節(jié) (共 4070572032 字節(jié)) 已使用 100.00%, 尚有 0 字節(jié)可用。
************************************************************************
You have following choices to free up space from recovery area:
1. Consider changing RMAN RETENTION POLICY. If you are using Data Guard,
   then consider changing RMAN ARCHIVELOG DELETION POLICY.
2. Back up files to tertiary device such as tape using RMAN
   BACKUP RECOVERY AREA command.
3. Add disk space and increase db_recovery_file_dest_size parameter to
   reflect the new space.
4. Delete unnecessary files using RMAN DELETE command. If an operating
   system command was used to delete files, then use RMAN CROSSCHECK and
   DELETE EXPIRED commands.

可以看出已經(jīng)達(dá)到db_recovery_file_dest_size規(guī)定的限制大小，處理方法如下：

1：在操作系統(tǒng)上刪除相關(guān)的文件，啟動數(shù)據(jù)庫，依然報前面的錯誤信息

2：由spfile生成pfile，增大pfile中的db_recovery_file_dest_size參數(shù)的值

3：由修改過的pfile生成spfile，啟動數(shù)據(jù)庫

4：使用rman，清理過期的數(shù)據(jù)

[Oracle@localhost ~]$ rman target/

RMAN> crosscheck archivelog all;

RMAN> delete expired archivelog all;

5：查看recovery_file_dest動態(tài)性能視圖

SQL> desc v$recovery_file_dest;

分析：flash_recovery_area初始化參數(shù)定義的值，一般用來存放歸檔日志(archivelog)和rman的備份集(backupset)，Oracle 11g r2 64位安裝完后，db_recovery_file_dest_size為3882M，為了防止oracle因?yàn)檫@個原因崩潰，應(yīng)當(dāng)根據(jù)需要適當(dāng)調(diào)整這個值的大小，并定期清理過期的日志信息

SQL> show parameter db_recovery;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest                string      /u01/flash_recovery_area
