Oracle數據庫可以運行在兩種模式下:歸檔模式(archivelog)和非歸檔模式(noarchivelog)
檢查歸檔模式命令
SQL> archive log list
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence
Current log sequence
設置歸檔模式
SQL> shutdown immediate;
Database closed
Database dismounted
ORACLE instance shut down
SQL> startup mount
ORACLE instance started
Total System Global Area
Fixed Size
Variable Size
Database Buffers
Redo Buffers
Database mounted
SQL> alter database archivelog;
Database altered
SQL> alter database open;
Database altered
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence
Next log sequence to archive
Current log sequence
如果需要停止歸檔模式
log_archive_start = true
重啟數據庫此參數生效
archive log start
使數據庫啟用自動歸檔
SQL> show parameter db_recovery
NAME TYPE VALUE
db_recovery_file_dest string /home/oracle/ora
very_area/
db_recovery_file_dest_size big integer
可以修改db_recovery_file_dest_size參數的大小
alter system set db_recovery_file_dest_size=
