oracle中wallet加密的几个测试笔记
时间：2022-06-29 09:45:23 编辑：袖梨 来源：一聚教程网
oracle wallet使用与维护
从Oracle10gR2开始, 通过使用Oracle Wallet达到任意用户不使用密码登录数据库(非操作系统认证方式),这对于用脚本登录数据库进行操作来说是非常有用的；尤其对于企业安全要求很高，不希望用户名和密码明文存在配置文件中，而且对于密码的维护是极为方便的，比如我把wallet放在指定路径下，当修改密码时，只需统一覆盖wallet即可，对于有大量应用服务器尤为方便。
TDE中比较核心部分为wallet,对于这部分进行测试,对钱包加密有更加深刻的理解.

通过测试我们发现当钱包中含cwallet.sso之时,wallet就会随库启动而open,当cwallet.sso被删除之后,wallet无法随库启动而open,由此可见,wallet是否随库启动而open取决于cwallet.sso文件.
修改wallet密码
[oracle@localhost wallets]$ orapki wallet change_pwd -wallet /home/u01/oracle/network/wallets
> -oldpwd xifenfei123 -newpwd www.111com.net

如果wallet文件丢失,没有办法open钱包,也就是说加密数据无法读取.备份ewallet.p12文件非常重要
在客户端使用wallet无密码登录的步骤:
1.创建wallet(tnsname.ora里面的连接串，sqlnet.ora文件内容都要复制到客户端)
2.把wallet复制到客户端指定路径（注意文件权限和属主）
3.修改客户端的tnsname.ora文件里连接服务器的连接串为创建时的连接串，在sqlnet.ora文件里添加如下内容：
WALLET_LOCATION=(SOURCE=(METHOD=FILE)(METHOD_DATA=(DIRECTORY=e:tempwallet)))
SQLNET.WALLET_OVERRIDE = TRUE
4.在sqlplus无密码等里测试
sqlplus /@skate_192.168.1.9
在jdbc里连接数据库密码形式如下：
public static Connection getConnection() throws SQLException {
DriverManager.registerDriver(new OracleDriver());
Connection conn = DriverManager
.getConnection("jdbc:oracle:oci:/@tnskate");
conn.setAutoCommit(false);
return conn;
}
