我把当初的步骤在描述一下：

1、目标数据库所有文件没有，仅保存有arch文件

2、作恢复：

run

{allocate channel ch00 type 'sbt_tape';

restore controlfile;

restore database;

recover database;

release channel ch00;}

运行正常，需要的文件都restore，recover 的时候，需要的一部分arch文件也从备份中读出，但是

由于需要的其后一部分arch文件磁带库里没有，所以最终没有正确结束，于是运行svrmgrl，作recover database 并auoto，最终alter database open resetlogs;

数据库正常了，但是以前定时的正常备份不知为什么不行了，查了资料也得不到答案

于是注销掉目标库并重新注册，有点奇怪的时，在执行register database;命令后，除了前几行什么compile正常，一直光标闪动，不结束，等了近一个多小时也没反应，但是查找目录库里db表里已经注册上了，就直接关掉了。

于是作了一个简单的测试：

run

{allocate channel ch00 type 'sbt_tape';

backup tablespace tools;

release channel ch00;}

也是很长时间没反应，今早一看报如下错误：

采用veritas netbackup5.0

netbackup报的错是

请各位指教呀
