Oracle启动或关闭归档模式

Posted 2020-10-01 fosonR

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 Automatic archival             Disabled Archive destination            USE_DB_RECOVERY_FILE_DEST Oldest online log sequence     228Current log sequence          230
