Oracle启动或关闭归档模式

在Oracle安装后，默认归档模式开启，大量的日志会瞬间填满磁盘，所以在开发环境，经常需要关闭归档模式。

1.管理员身份连接数据库

$sqlplus user/passwd@dbname as sysdba

2.查看当前归档模式，是归档还是非归档

SQL> archive log list;

3.关闭数据库

SQL> shutdown immediate;

Database closed.

Database dismounted.

ORACLE instance shut down.

4.启动数据库到mount状态

SQL> startup mount;

ORACLE instance started.
