ORACLE11g 重裝系統后根據dbf恢復數據庫

1.安裝一個和原系統一致的oracle 環境，主要包括版本、數據名sid、實例名、路徑和數據庫編碼一致

2.修改listener.ora的參數

1. SID_LIST_LISTENER =
2. (SID_LIST =
3. (SID_DESC =
4. (SID_NAME = PLSExtProc)
5. (ORACLE_HOME = D:\oracle\product\ 10.1.0\db_1)
6. (PROGRAM = extproc)
7. )
8. (SID_DESC =
9. (GLOBAL_DBNAME = orcl) //如果已經有這個orcl了，這個文件就不用修改
10. (ORACLE_HOME = D:\oracle\product\ 10.1.0\db_1) //這里要根據你的實際路徑來
11. (SID_NAME = orcl)
12. )
13. )
14. LISTENER =
15. (DESCRIPTION_LIST =
16. (DESCRIPTION =
17. (ADDRESS_LIST =
18. (ADDRESS = (PROTOCOL = TCP)(HOST = lypch )(PORT = 1521))
19. )
20. (ADDRESS_LIST =
21. (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
22. )
23. )
24. )

3.修改tnsnames.ora的參數

 

1. AMMICLY =
2. (DESCRIPTION =
3. (ADDRESS = (PROTOCOL = TCP)(HOST = lypch )(PORT = 1521))
4. (CONNECT_DATA =
5. (SERVER = DEDICATED)
6. (SERVICE_NAME = orcl)
7. (UR=A) //參數允許只進行管理性的連接，數據庫nomount,mount或者restricted時，動態監聽顯示狀態為BLOCKED時，客戶端配置UR=A進行連接。
8. )
9. )
10. EXTPROC_CONNECTION_DATA =
11. (DESCRIPTION =
12. (ADDRESS_LIST =
13. (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
14. )
15. (CONNECT_DATA =
16. (SID = PLSExtProc)
17. (PRESENTATION = RO)
18. )
19. )

3.SQL>shutdown immediate      停止服務，將新安裝的oracle的dbf備份后刪除，將原dbf拷貝到新安裝的目錄下F:\app\toshiba\oradata\orcl

 

4.原oracle庫主目錄下的FLASH_RECOVERY_AREA目錄全部覆蓋到新安裝的oracle對應目錄下

 

5. SQL>startup                          再次啟動服務
