ORACLE RMAN ENCRYPTION(WALLET)

如下这篇文章，主要是做一个简单的rman加密的演示

启用db的加密

RMAN> CONFIGURE ENCRYPTION FOR DATABASE on
2> ;new RMAN configuration parameters:
CONFIGURE ENCRYPTION FOR DATABASE ON;
new RMAN configuration parameters are successfully stored

查看数据库默认的加密算法

SQL> select * from v$rman_encryption_algorithms;ALGORITHM_ID ALGORITHM_NAME  ALGORITHM_DESCR IS_DEFAUL RESTORE_O
------------ --------------- --------------- --------- ---------1 AES128      AES 128-bit key        YES       NO2 AES192      AES 192-bit key        NO        NO3 AES256      AES 256-bit key        NO        NORMAN> show encryption algorithm;RMAN configuration parameters for database with db_unique_name ORCL are:
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default

设定密码

RMAN> set encryption on identified by "Oracle123" only;executing command: SET encryption

尝试去备份

ORA-28365: wallet is not open 
该错误的解释：[oracle@hdp backupset]$ oerr ora 28365
28365, 0000, "wallet is not open"
// *Cause:  The security module wallet has not been opened.
// *Action: Open the wallet.

去相应目录创建wallet文件夹就可以了

– 创建钱夹

[oracle@hdp orcl]$ mkdir wallet
[oracle@hdp orcl]$ pwd
/u01/app/oracle/admin/orcl
[oracle@hdp orcl]$ ls
adump  dpdump  pfile  wallet

再次去备份的时候发现可以正常备份了。

然后我们再试着去恢复

原来是wallet没有打开

 1*  SELECT * FROM V$ENCRYPTION_WALLET

打开钱包后的操作,我们才可以继续我们的操作
