Restore Production Database to Development Platform A step-by-step example

Overview of setup and configuration

  • Oracle Enterprise Edition 11gR2. 11.2.0.1.0 Linux RH5 NetBackup 6.5.5
  • Identical environments:
    • Identical versions of Oracle.
    • Same ORACLE_HOME and ORACLE_BASE.
    • The archive log directory is defined to be the Flash Recovery Area:
  • You know the DBID.
  • Control file autobackup feature enabled with the default format.

NetBackup MML considerations

Restoring from tape using the NetBackup MML
MANDITORY requirement on the NetBackup Master Server.

On the NBU Master server the following directory and file must exist:
/[netbackup install]/db/altnames/No.Restrictions

Restore

Restore the spfile to pfile.

RMAN> run {
allocate channel t1 device type sbt;
send ‘NB_ORA_SERV=NBU_MasterServer.com, NB_ORA_CLIENT=Original_Client.com’;
set controlfile autobackup format for device type sbt to ‘%F’;
restore spfile
to pfile ‘?/dbs/initprod.ora’
from autobackup;
shutdown abort;
}

图文详解安装NetBackup 6.5备份恢复Oracle 10g rac 数据库(修订)

我们使用Linux平台进行测试,OS版本为Oracle Enterprise Linux 5.5 x86_64:
[root@nas servsoft]# cat /etc/issue
Enterprise Linux Enterprise Linux Server release 5.5 (Carthage)
Kernel \r on an \m

Netbackup 6.0仅支持2.4内核的Linux版本,2.6内核的Linux版本(主流的包括RHEL4,5 Centos等)需要使用NBU,只能安装Netbackup 6.5或以上版本。
现在我们有三台主机: rh1(rac的2号节点),rh2(rac的1号节点),nas(NBU Server)。
首先需要安装的是Netbackup Server端软件,当然你需要用到安装介质,你可以尝试在Veritas的官方网站下载到最新的版本;获取到安装介质后,我们首先要解压它:

[root@nas netbackup]# cp NetBackup_6.5_LinuxRedhat2.6.tar.gz /tmp

[root@nas tmp]# gunzip NetBackup_6.5_LinuxRedhat2.6.tar.gz

[root@nas tmp]# tar -xvf NetBackup_6.5_LinuxRedhat2.6.tar

在进入安装前确认xinetd服务正确运行着:

[root@nas tmp]# service xinetd status

xinetd (pid  2886) is running...

[root@nas NB_65_LinuxR_x86_20070723]# ./install

Do you want to install NetBackup and Media Manager files? [y,n] (y) y

NetBackup and Media Manager are normally installed in /usr/openv.

Is it OK to install in /usr/openv? [y,n] (y) y

Reading NetBackup files from /tmp/NB_65_LinuxR_x86_20070723/linuxR_x86/anb

...................

Enter the full path name to the directory where the

appropriate installics script is located followed by

a  to continue. This script will then install

the package(s).

        OR

Enter q to stop this install and abort.

此时我们需要输入Netbackup ISC(Infrastructure Core Services)软件所在的目录,当然你也可以从Veritas官方网站下载到该软件包,尝试解压:

[root@nas tmp]# cp NetBackup_6.5_ICS_LinuxX86.tar.gz /tmp

[root@nas tmp]# cd /tmp

[root@nas tmp]# gunzip NetBackup_6.5_ICS_LinuxX86.tar.gz

[root@nas tmp]# tar -xvf NetBackup_6.5_ICS_LinuxX86.tar

则此时ISC安装介质位于/tmp/NB_65_ICS_1.4.37.0_LinuxX86下,在原终端窗口中输入该目录

Enter q to stop this install and abort.

/tmp/NB_65_ICS_1.4.37.0_LinuxX86

Installing VRTSpbx...

A NetBackup Server or Enterprise Server license key is needed

for installation to continue.

Enter license key:

继续安装,此时需要输入您所购买的License注册码;如果您没有购买该软件但仍想使用的话,

可以尝试下面一串字符:DEX6-23FJ-T92R-O4O4-O4O4-K777-7777-EPXP-3XO。

Enter license key: DEX6-23FJ-T92R-O4O4-O4O4-K777-7777-EPXP-3XO

DEX6-23FJ-T92R-O4O4-O4O4-K777-7777-EPXP-3XO:

        NetBackup Enterprise Server Base product with all the features enabled

        has been registered.

All additional keys should be added at this time.

Do you want to add additional license keys now? [y,n] (y) n

Use /usr/openv/netbackup/bin/admincmd/get_license_key

to add, delete or list license keys at a later time.

Installing NetBackup Enterprise Server version: 6.5

If this machine will be using a different network interface than the

default (nas), the name of the preferred interface should be used

as the configured server name.  If this machine will be part of a

cluster, the virtual name should be used as the configured server name.

Would you like to use "nas" as the configured

name of the NetBackup server? [y,n] (y) y

Is nas the master server? [y,n] (y) y

Do you have any media servers? [y,n] (n) n

Checking /etc/services for the needed NetBackup and Media Manager services.

Copying original /etc/services file to /etc/services.NBU_062910.14:27:41

Editing /etc/services to update NetBackup and Media Manager services.

/etc/services will be updated to add the following entries for

NetBackup/Media Manager.

bpjobd  13723/tcp       bpjobd

vmd     13701/tcp       vmd

acsd    13702/tcp       acsd

tl8cd   13705/tcp       tl8cd

tldcd   13711/tcp       tldcd

odld    13706/tcp       odld

tl4d    13713/tcp       tl4d

tshd    13715/tcp       tshd

tlmd    13716/tcp       tlmd

tlhcd   13717/tcp       tlhcd

rsmd    13719/tcp       rsmd

...................

好了Netbackup Server端软件已经在NAS主机上安装完成,接下来我们需要进一步配置备份策略。

将/usr/openv/netbackup/bin路径加入到你的用户环境变量PATH中,以方便调用相关执行文件;

并在具有X11 forwarding功能的软件中(譬如Xmanager)中输入jnbSA命令,

您可能遭遇java.lang.UnsatisfiedLinkError: /usr/openv/java/jre/lib/i386/libawt.so: libXp.so的错误,

一般是由于没有安装libXp(i386和x86_64版本的都装一下)包所导致的。

正确安装的话输入jnbSA命令可以看到以下界面:

接着我们需要定义存储单元(Storage Unit),如果你同我一样没有真实的磁带机的话那么我们可以定义普通Disk

类型的存储单元, 选择Netbackup Management->Storage -> Storage Unit,在右边分隔栏右键点击New Storage Unit,

为你的存储单元起一个名字,并输入相关存储目录:

接下来点击NetBackup Management->Policies 选项定义Oracle备份使用到的备份策略,启用Backup Policy Configuration Wizard,并选择Oracle为备份策略类型:

在客户端列表(client list)中加入需要备份2台RAC所在主机,分别为rh1,rh2;硬件与操作系统选择Linux,Redhat2.6

好了,server端的配置完成了,接下来我们安装client端软件,安装前确认你已经获得了相关安装介质,以NBU6.5举例来说你需要有:NetBackup_6.5_CLIENTS2.tar.gz和NetBackup_6.5_UnixOptions.tar.gz 分别为Client端和Oracle Agent软件。

[root@rh2 tmp]# gunzip  NetBackup_6.5_UnixOptions.tar.gz
[root@rh2 tmp]# gunzip  NetBackup_6.5_CLIENTS2.tar.gz
[root@rh2 tmp]# tar -xvf NetBackup_6.5_UnixOptions.tar
[root@rh2 tmp]# tar -xvf NetBackup_6.5_CLIENTS2.tar
[root@rh2 tmp]# cd NB_65_CLIENTS2_20070723/
[root@rh2 NB_65_CLIENTS2_20070723]# ./install
