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
SQL*Plus: Release 11.2.0.1.0 Production on Tue Jun 17 23:50:55 2014
Copyright (c) 1982, 2010, Oracle.  All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

 

2.查看当前归档模式，是归档还是非归档

SQL> archive log list;
Database log mode              No Archive Mode
Automatic archival             Disabled
Archive destination            USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     228Current log sequence           230

 

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.
 
Total System Global Area 3423965184 bytes
Fixed Size                  2180544 bytes
Variable Size            2013268544 bytes
Database Buffers         1392508928 bytes
Redo Buffers               16007168 bytes
Database mounted.

 

5.启动归档模式

 

SQL> alter database archivelog;
 
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     228Next log sequence to archive  230Current log sequence          230

 

6.启动数据库

 

SQL> alter database open;
Database altered.

 

7.关闭归档模式

 

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount;
ORACLE instance started.
 
Total System Global Area 3423965184 bytes
Fixed Size                  2180544 bytes
Variable Size            2013268544 bytes
Database Buffers         1392508928 bytes
Redo Buffers               16007168 bytes
Database mounted.
SQL> alter database noarchivelog;
 
Database altered.
 
SQL> archive log list;
Database log mode              No Archive Mode
