1，查看当前归档模式
SQL> archive log list;
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 210
Current log sequence 212
2，重启数据库到mount状态
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount;
ORACLE instance started.
Total System Global Area 6442450944 bytes
Fixed Size 2030368 bytes
Variable Size 1358955744 bytes
Database Buffers 5066719232 bytes
Redo Buffers 14745600 bytes
Database mounted.
3，开启归档模式
SQL> alter database archivelog;
Database altered. [NextPage] 4，打开数据库
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 210
Next log sequence to archive 212
Current log sequence 212
SQL> archive log start;
Statement processed.
5，关闭归档模式的步骤
SQL> startup mount;
SQL> alter database noarchivelog;
SQL> alter database open;
6，9i和10g的区别
9i中需要修改初始化参数
log_archive_start = true
10g中已经废弃该参数
