ORACLE 官方文档中介绍 CATALOG 命令只能注册在磁盘中的备份片，在现在多数环境中备份时，备份集都是放到磁带库中，那么 CATALOG 命令真就不支持注册磁带库中的备份片？其实是支持的，MOS 也有相当的文档介绍。下面就在 11.2.0.3+NBU 7.1 的环境中来测试一下。
1，环境介绍
这里由于要使用磁带，所以使用 NBU 来备份 ORACLE 数据库。
数据库环境
www.htz.pw > select * from V$version;
BANNER ——————————————————————————– Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 – 64bit Production PL/SQL Release 11.2.0.3.0 – Production CORE 11.2.0.3.0 Production TNS for Linux: Version 11.2.0.3.0 – Production NLSRTL Version 11.2.0.3.0 – Production

NBU环境
[root@nbu71 ~]# bpgetconfig -s nbu71 Master Linux, RedHat2.6 7.1.0 NetBackup 7.1 710000 /usr/openv/netbackup/bin Linux 2.6.18-308.el5 |
2，备份数据库
这里通过 NBU 发起对 ORACLE 的备份，略。
3，停客户端 NBU 进程
这里关闭客户端，本来是想手动通过 rman 来删除备份集，不更新 nbu 服务器上的备份信息，结果失败，就算关闭 nbu 客户端的进程，NBU 服务器上面的信息还是更新了。
[root@www.htz.pw ~]#bp.kill_all
Looking for NetBackup processes that need to be terminated.

4，在 ORACLE 中删除备份集，这里需要注意在 RMAN 中通过 delete 删除备份集，会自动在 NBU 中删除相应的备份信息，但是备份集是没有真实的删除的，在后面也可以看到。
RMAN> ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE SBT_TAPE;
allocated channel: ORA_MAINT_SBT_TAPE_2 channel ORA_MAINT_SBT_TAPE_2: SID=40 device type=SBT_TAPE channel ORA_MAINT_SBT_TAPE_2: Veritas NetBackup for Oracle – Release 7.1 (2011020316)

RMAN> list backup device type sbt_tape;
specification does not match any backup in the repository |
5 在 NBU 中查看备份信息
这里不能发现 orcl9i 的任何备份集的信息
[root@www.htz.pw ~]#bp.start_all Starting vnetd… Starting bpcd… Starting nbftclnt… Starting bmrbd… 从 NBU 中已经找不到任何与 orcl9i 客户端相关的备份集，这里有点想不到，NBU客户端都已经关闭了，为什么 RMAN 中的操作还是更新了 NBU 服务器上面的东西 [root@www.htz.pw ~]#bplist -S nbu71 -C orcl9i -t 4 -R -l EXIT STATUS 227: no entity was found
[root@nbu71 nbu]# bpimagelist -client orcl9i no entity was found |
6，手动注册备份集
这里会看到注册备份集会报错，因为在 NBU 中就找不到此备份文件的信息
RMAN> CONFIGURE CHANNEL DEVICE TYPE ‘SBT_TAPE’ PARMS ‘ENV=(NB_ORA_SERV=nbu71,NB_ORA_CLIENT=orcl9i)’;

7 在 NBU 服务器上面查看备份文件信息
这里将备份文件存在在磁盘目录中的，对 ORACLE 客户端来说，是没有影响的，通道仍然是配置是 TAPE。这里可以看到 NBU 的备份文件还存在，只要备份文件还存在，一切都好办了。

9 RMAN重新注册备份片
使用 bplist 查看备份文件信息，已经可以看到 orcl9i 客户端备份片的名字了， NBU 备份 ORACLE，其实也是备份的文件，RMAN 备份使用 BACKUP 备份生成备份片，NBU 在备份备份片。这里我们看到的是备份片的名字。
