说明：

10.10.0.53 ctdb04 ,假设此为使用中重要DB ，通过veritas 全库备份至磁带机。

10.10.0.59 cdim ,veritas server软件服务器，(windows 2000)。

情况(一)：拥有控制文件的恢复

说明：

1，53数据库有完整全备份在磁带机中（包括controlfile）,其参数文件和controlfile也有第三方手段进行备份。

2，53数据库宕，需要用磁带机中的备份数据恢复至53服务器中。

操作流程如下：

1）

RMAN> run{

2> allocate channel c1 type 'sbt_tape';

3> restore database;

4> recover database;

5> release channel c1;}

即可以完成全数据库的还原与恢复。

情况(二)：丢失控制文件的恢复

说明：

1， 53数据库有完整全备份在磁带机中（包括controlfile）,但丢失了第三放备份的控制文件。

2，数据库宕机，需要用将数据恢复至53服务器中。

A，利用和数据文件一起的备份的控制文件进行恢复的操作流程如下：

1） 检查上一次完整全库RMAN备份的日志；

cat $ORACLE_HOME/testhot_database_backup.sh.out

2) 找到数据备份，归档日志备份，控制文件备份的备份集
