1.  什么是Wallet

A datastructure used to store and manage security credentials for an individualentity.

从Oracle10gR2开始, 通过使用Oracle Wallet达到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。

2.  Wallet的创建和管理

1.创建wallet

[oracle@daidai ~]$ mkdir -p/tmp/test_wallet

[oracle@daidai ~]$ mkstore-wrl /tmp/test_wallet –create

[oracle@daidai ~]$ cd /tmp/test_wallet/

[oracle@daidai test_wallet]$ ls

cwallet.sso  ewallet.p12

配置连接串tnsnames.ora

WALLET_OCP11G =

 (DESCRIPTION =

   (ADDRESS = (PROTOCOL = TCP)(HOST = daidai.com)(PORT = 1522))

   (CONNECT_DATA =

     (SERVER = DEDICATED)

     (SERVICE_NAME = ocp11g)

    )

  )

配置sqlnet.ora

WALLET_LOCATION=(SOURCE=(METHOD=FILE)(METHOD_DATA=(DIRECTORY=/tmp/test_wallet)))

SQLNET.WALLET_OVERRIDE = TRUE

把登入数据库的用户认证信息添加到wallet中

[oracle@daidai ~]$ mkstore --help

测试连接

至此，就可以使用wallet连接

[oracle@daidai ~]$ sqlplus/@wallet_ocp11g

oracle.security.client.connect_string1 =wallet_ocp11g

更改wallet里用户认证信息的内容

mkstore -wrl/tmp/test_wallet -modifyEntry oracle.security.client.password1skatepwd1

mkstore -wrl/tmp/test_wallet -modifyEntry oracle.security.client.username1skate1

3.  迁移linux wallet至window 7

1. 按照linux中的样式修改tnsname.ora[IP & port]和sqlnet.ora[walletpath]，注意测试连通性

2. mkstore -wrl e:/test_wallet –create

3. 拷贝出linux中wallet文件覆盖windows中的wallet文件

windows迁移至linux，我没有测试。
