1 使数据库处于ARCHIVELOG模式
$svrmgrl
SVRMGR> connect internal
SVRMGR> ALTER DATABASE ARCHIVELOG;
SVRMGR>ARCHIVE log start
SVRMGR>ALTER DATABASE OPEN;
2 获取最早的联机日志序列号
SVRMGR> archive log list
3 将要备份的表空间设为热备份模式
SVRMGR> ALTER TABLESPACE tablespace_name BEGIN BACKUP;
4 使用操作系统命令备份改表空间的datafile
5 取消该表空间的热备份模式
SVRMGR> ALTER TABLESPACE tablespace_name END BACKUP;
6 如还有其他要备份的表空间，重复3-5
7 强制日志切换
SVRMGR> ALTER SYSTEM SWITCH LOGFILE ;
8 使用os命令备份所有归档日志文件
9 备份control file
SVRMGR>ALTER DATABASE BACKUP CONTROL FILE TO 'filespecif' ;
