概述：跨操作系统平台数据库迁移，windows to linux 步骤记录；
实验步骤：
（一）、linux平台安装好数据库软件及配置好监听；
（二）、备份windows数据库；
（三）、linux平台进行数据库恢复操作；
（四）、linux平台进行数据库恢复后的相关操作；
windows 备份数据库：
run {
configure device type disk parallelism 4;
backup database format ‘C:bakfull_%U‘;
}
模拟数据库还在运行，多切换几个日志进行归档：
alter system switch logfile; （多次执行）
备份控制文件
alter database backup controlfile to ‘C:bakctl.bak‘;
将备份文件、备份控制文件、全量的归档 传输与linux平台
linux平台进行恢复操作：
启动linux至nomount状态：
[[email protected] dbs]$ cat initcube.ora
db_name=‘cube‘
memory_target=500M
processes = 150
audit_file_dest=‘/u01/ora/app/admin/cube/adump‘

db_domain=‘‘
db_recovery_file_dest=‘/u01/ora/app/flash_recovery_area‘

dispatchers=‘(PROTOCOL=TCP) (SERVICE=ORCLXDB)‘

undo_tablespace=‘UNDOTBS1‘
control_files = (/u01/ora/app/data/control1.ctl, /u01/ora/app/data/control2.ctl)

恢复数据：
