在归档日志模式下,有可能会遇到归档日志大小超过最大值而出现讨厌的ORA-00257错误,,前面说了如何把归档日志空间变大。而在普通的开发环境下,其实是根本用不着归档日志的,设个时候我们就把数据库的归档日志给禁用了,也就是说把数据库变为非归档日志模式,应该怎么做呢。
在这里所有的操作要在数据库的那台机器上操作,用SYS用户进行登录,首先设置归档进程关闭。
alter system set log_archive_start=false scope=spfile;
然后关闭数据库
shutdown immediate
再后面把数据库启动到mount的模式
startup mount
关闭flash闪回数据库模式,如果不关闭的话,在后面关闭归档日志的时候就会出现讨厌的ORA-38774错误。
alter database flashback off
接着把数据库改为非归档模式
alter database noarchivelog;
都修改好了以后,然后打开数据库
Alter database open;
察看一下归档日志的空间大小
select * from v$recovery_file_dest;
接着看一下log日志的状态
select * from v$log;
再看一下闪回日志使用状况
select * from v$flash_recovery_area_usage;
