【学习笔记】Oracle RMAN CATALOG命令手动注册磁带库中的备份片

时间:2016-10-31 22:22   来源:Oracle研究中心   作者:HTZ   点击:

天萃荷净 Oracle研究中心学习笔记: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。

下面就是11.2.0.3+NBU 7.1的环境中来测试一把。

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
oracleplus.net> 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

oracleplus.net> !lsb_release -a
LSB Version: :core-3.0-amd64:core-3.0-ia32:core-3.0-noarch:graphics-3.0-amd64:graphics-3.0-ia32:graphics-3.0-noarch
Distributor ID: RedHatEnterpriseAS
Description: Red Hat Enterprise Linux AS release 4 (Nahant Update 8)
Release: 4
Codename: NahantUpdate8
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@oracleplus.net ~]#bp.kill_all

Looking for NetBackup processes that need to be terminated.

Looking for more NetBackup processes that need to be terminated.
Stopping bpcd…
Stopping vnetd…

The following processes are still active
oracle 6332 1 0 05:18 00:00:00 /usr/openv/netbackup/bin/bpcd -standalone
oracle 6336 1 0 05:18 00:00:00 /usr/openv/netbackup/bin/bpcd -standalone
Do you want this script to attempt to kill them [y,n] (y) y
Killing remaining processes…
Waiting for processes to terminate…

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> delete backupset device type SBT_TAPE;

List of Backup Pieces
BP Key BS Key Pc# Cp# Status Device Type Piece Name
——- ——- — — ———– ———– ———-
37 37 1 1 AVAILABLE SBT_TAPE bk_60_1_862117780
38 38 1 1 AVAILABLE SBT_TAPE bk_61_1_862117965
39 39 1 1 AVAILABLE SBT_TAPE bk_62_1_862117982
40 40 1 1 AVAILABLE SBT_TAPE bk_59_1_862117780

42 42 1 1 AVAILABLE SBT_TAPE al_64_1_862118319
43 43 1 1 AVAILABLE SBT_TAPE cntrl_65_1_862118335

Deleted 7 objects

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@oracleplus.net ~]#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@oracleplus.net ~]#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)’;

old RMAN configuration parameters:
CONFIGURE CHANNEL DEVICE TYPE ‘SBT_TAPE’ PARMS ‘NB_ORA_SERV=nbu71,NB_ORA_CLIENT=orcl9i’;
new RMAN configuration parameters:
CONFIGURE CHANNEL DEVICE TYPE ‘SBT_TAPE’ PARMS ‘ENV=(NB_ORA_SERV=nbu71,NB_ORA_CLIENT=orcl9i)’;
new RMAN configuration parameters are successfully stored

RMAN> CATALOG DEVICE TYPE ‘SBT_TAPE’ BACKUPPIECE ‘bk_62_1_862117982’;

allocated channel: ORA_SBT_TAPE_1
channel ORA_SBT_TAPE_1: SID=41 device type=SBT_TAPE
channel ORA_SBT_TAPE_1: Veritas NetBackup for Oracle – Release 7.1 (2011020316)

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。
