Oracle RMAN 备份到AWS 云

    首次尝试将oracle数据库备份到AWS 云，以前一般都是备份到磁带库或者磁盘，现在有了云就更方便了。这里主要是使用AWS 的S3存储作为SBT设备进行备份。至于什么是AWS,什么是S3，麻烦大家参考：http://www.amazonaws.cn/products/  具体操作步骤如下：

先决条件： 你要有一个AWS accunt（AWS access key ID 与 AWS secret key）,你还需要有ORACLE的OTN账号与密码

    1、安装Centos 6.6 64位操作系统（具体过程略）

    2、 安装JAVA 1.8 JDK （具体过程略）

    3、 安装 Oracle 11G数据库 （具体过程略）

    4、下载OSB模块 ，可以到http://www.oracle.com/technetwork/database/database-technologies/secure-backup/secure-backup-s3-484709.html 查找到

    5、 解压缩osbws_installer.zip

[oracle@localhost ~]$ unzip osbws_installer.zip

. [oracle@localhost ~]$ java -jar osbws_install.jar

Oracle Secure Backup Web Service InstallTool, build 2015-06-22

No arguments supplied

Usage: java -jar osbws_install.jar

         -AWSID:        AWS Access Key ID

         -AWSKey:       AWS Secret Access Key

         -otnUser:      OTN Username

         -walletDir:    Directory to store wallet

         -configFile:   File name of config file

         -libDir:       Directory to store library

         -libPlatform:  Platform of library to download

         -location:     Location to store backups

         -proxyHost:    HTTP proxy host

         -proxyPort:    HTTP proxy port

         -proxyID:      HTTP proxy userid, if needed

         -proxyPass:    HTTP proxy password, if needed

         -newLogBucket:Force creation of new log bucket

         -reRegister:   Force user registration

当你看见类似上面的输出，则下载的osbws_install是正确的。

    6、编辑一个脚本文件叫：osbws.sh，然后输入如下内容：

java -jar osbws_install.jar -AWSID XXXXXXXXX  \

-AWSKey //XXXXXXXXX \

-otnUser XXXX@ABC.COM  \

-otnPass xxxx \

-walletDir$ORACLE_HOME/dbs/osbws_wallet  \

-libDir $ORACLE_HOME/lib/

解释：-AWSID 是AWS的 access key ID 例如：ABCDK234DDK39JDL

-AWSKey 是该acess key ID 的secrect key

-otnUser 与 -otnPass是你的oracle账号密码

    7、输入下面的命令：

[oracle@localhost ~]$ mkdir $ORACLE_HOME/dbs/osbws_wallet

[oracle@localhost ~]$ chmod +x osbws.sh

[root@localhost ~]# ntpdate stdtime.gov.hk   #切换root用户进行ntp网络时间同步，不同步会报错

    8、则行osbws.sh

[oracle@localhost ~]$ ./osbws.sh

查看$ORACLE_HOME/lib目录

ls $ORACLE_HOME/lib/*osb*

输出如：

/usr/oracle/app/oracle/product/11.2.0/dbhome_1/lib/libosbws11.so  /usr/oracle/app/oracle/product/11.2.0/dbhome_1/lib/libosbws.so

则AWS驱动已经安装成功。

    现在测试一下表空间备份与还原的操作，我先创建一个表空间以及一个测试用户，并在该用户下创建测试表。然后通过OSB备份到AWS上面.具体过程如下：

A、创建表空间：

SQL> create tablespace up2s3
  2  logging
  3  datafile '/usr/oracle/app/oracle/oradata/orcl/up2s3_01.dbf' SIZE 5M
  4  autoextend on;

Tablespace created.

2、创建用户

SQL> create user tests3 identified by test;
User created.

SQL>grant connect,resource to tests3;

Grant succeeded.

SQL> alter user tests3 default tablespace up2s3 ;

User altered.
SQL> conn tests3/test;
Connected.

SQL> create table test(id varchar(20));

Table created.

SQL> insert into test(id) values('abc');

1 row created.

SQL> select * from test;

ID
--------------------
abc

B、利用RMAN把up2s3表空间备份到云端,在rman输入：

RMAN> run {
2> allocate channel dev1 type
3> sbt parms='SBT_LIBRARY=/usr/oracle/app/oracle/product/11.2.0/dbhome_1/lib/libosbws11.so,
4> SBT_PARMS=(OSB_WS_PFILE=/usr/oracle/app/oracle/product/11.2.0/dbhome_1/dbs/osbwsorcl.ora)';
5> backup tablespace up2s3;
6> }

输出：

allocated channel: dev1
channel dev1: SID=32 device type=SBT_TAPE
channel dev1: Oracle Secure Backup Web Services Library

Starting backup at 21-JUL-15
channel dev1: starting full datafile backup set
channel dev1: specifying datafile(s) in backup set
input datafile file number=00005 name=/usr/oracle/app/oracle/oradata/orcl/up2s3_01.dbf
channel dev1: starting piece 1 at 21-JUL-15
channel dev1: finished piece 1 at 21-JUL-15
piece handle=01qck3eb_1_1 tag=TAG20150721T155035 comment=API Version 2.0,MMS Version 2.0.0.0
channel dev1: backup set complete, elapsed time: 00:00:25
Finished backup at 21-JUL-15
released channel: dev1

现在你可以尝试在rman使用list backupset 看到你刚刚的备份。

C、删除up2s3表空间，模拟表空间损毁。

SQL> alter tablespace up2s3 offline;

Tablespace altered.

[oracle@localhost ~]$ su -
Password:

[root@localhost ~]# mv /usr/oracle/app/oracle/oradata/orcl/up2s3_01.dbf /root/

SQL> alter tablespace up2s3 online;
alter tablespace up2s3 online
*
ERROR at line 1:
ORA-01157: cannot identify/lock data file 5 - see DBWR trace file
ORA-01110: data file 5: '/usr/oracle/app/oracle/oradata/orcl/up2s3_01.dbf'

D、现在通过RMAN去恢复up2s3表空间

RMAN> run {
2> allocate channel dev1 type
3> sbt parms='SBT_LIBRARY=/usr/oracle/app/oracle/product/11.2.0/dbhome_1/lib/libosbws11.so,
4> SBT_PARMS=(OSB_WS_PFILE=/usr/oracle/app/oracle/product/11.2.0/dbhome_1/dbs/osbwsorcl.ora)';
5> restore tablespace up2s3;
6> recover tablespace up2s3;
7> }

SQL> alter tablespace up2s3 online;


Tablespace altered.

SQL> conn tests3/test
Connected.
SQL> select * from test;

ID
--------------------
abc
