我们大家都知道Oracle数 据库可以在2种模式下运行,即,归档模式(archivelog)与非归档模式(noarchivelog),归档模式的主要作用是提高数据库的可恢复 性,其实际生产的数据库都应该运行在此模式下,
归档模式应该和相应的备份策略相结合,只有归档模式没有相应的备份策略只会带来麻烦。
1.shutdown normal或shutdown immediate关闭数据库
- [oracle@jumper oracle]$ sqlplus "/ as sysdba"
 - SQL*Plus: Release 9.2.0.4.0 - Production on Sat Oct 15 15:48:36 2005
 - Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.
 - Connected to:
 - Oracle9i Enterprise Edition Release 9.2.0.4.0 - Production
 - With the Partitioning option
 - JServer Release 9.2.0.4.0 - Production
 - SQL> shutdown immediate;
 - Database closed.
 - Database dismounted.
 - ORACLE instance shut down.
 
2.启动Oracle数据库到mount状态
- SQL> startup mount;
 - ORACLE instance started.
 - Total System Global Area 101782828 bytes
 - Fixed Size 451884 bytes
 - Variable Size 37748736 bytes
 - Database Buffers 62914560 bytes
 - Redo Buffers 667648 bytes
 - Database mounted.
 
3.启用或停止归档模式
如果要启用归档模式,此处使用
- alter database archivelog 命令。
 - 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 /opt/oracle/oradata/conner/archive
 - Oldest online log sequence 148
 - Next log sequence to archive 151
 - Current log sequence 151
 
上述的相关内容就是对如何启动或关闭Oracle数据库的归档模式的描述,希望会给你带来一些帮助在此方面。
