OracleRMAN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
