啟用Oracle自動歸檔模式

發布時間: 2012/8/29 17:17:17

1.創建保存備份的目錄
mkdir /u01/Oracle/oradata/archive/archive
chown -R Oracle /u01/oracle/oradata/archive/archive
2. 切換到Oracle用戶
sqlplus /nolog
connect /as sysdba
3. 設置歸檔日志目標地址

查看數據庫是否在歸檔模式

SQL> select log_mode from v$database;

LOG_MODE
------------------------
NOARCHIVELOG

SQL> show parameter 'log_archive_dest_1'

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest_1                   string
log_archive_dest_10                  string
log_archive_dest_11                  string
log_archive_dest_12                  string
log_archive_dest_13                  string
log_archive_dest_14                  string
log_archive_dest_15                  string
log_archive_dest_16                  string
log_archive_dest_17                  string
log_archive_dest_18                  string
log_archive_dest_19                  string

SQL> alter system set log_archive_dest_1='location=/u01/

System altered.

SQL> show parameter log_archive_format;

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_archive_format string %t_%s_%r.dbf

--設置日志文件名稱格式重起數據庫后生效
alter system set log_archive_dest_1='location=/u01/

SQL> System altered.

4.關閉數據庫
SQL> shutdown immediate;

5. 啟動數據庫并加載
SQL> startup mount;

6.將數據庫切換為歸檔模式
SQL> alter database archivelog;

SQL> select log_mode from v$database;

LOG_MODE
------------------------
ARCHIVELOG

7.打開數據庫
SQL> alter database open;
8. 切換日志，強迫歸檔
