昨天在公司配置数据库时，向wallet中增加了一个新的数据库，现实无需输入用户名与密码来登陆数据库，香港服务器，增加完成后，导致整个监控系统都是报用户名与密码的错误，无法登陆来数据库。但是ORACLE用户是能正常登陆数据库，不需要输入密码。其实原因很简单，因为我们的监控系统是nagios，而wallet相关的文件的默认权限是600，除ORACLE外其它的用户都是不可以读写的，正常情况下我们是改成了777的权限，让其它的用户也能使用钱包这个功能，当是我对wallet进行新增加一个数据库时，wallet会自己把cwallet.sso与ewallet.p12文件的权限自己改成600。这就导致了今天我的悲剧。
下面是wallet的配置/管理/维护/现象的模拟
1.创建wallet
2.配置wallet到sqlnet.ora中
3.查看wallet的命令帮忙
wallet这个很好，因为直接用help就可以看到命令的帮忙了，不需要我们再去记复杂的参数，只用记住mkstore这个命令来管理wallet就可以了。
4.增加数据库到wallet中去，服务器空间，并测试是否成功
5.查看entry
6.创建默认用户与密码
这样可以实现，登陆所以的数据库都可以使用默认的用户与密码
7.当默认用户与手动增加的数据库信息到wallet中时，那一个生效呢？
下面我们测试一下，当wallet里面创建了默认的用户与密码时，香港空间，手动再增加一个增加的信息到wallet时，到底是默认用户还是手动增加的生效呢？其实是手动增加的生效。
8.下面测试的是通过mkstore修改wallet中的内容后，导致wallet相关的文件，权限自动改成600.
9. 当用户的密码发生变化的时候需要修改wallet中的密码
10.查看wallet中有那些认证的信息
11 从wallet删除一个net service的配置信息
12.修改默认的用户名
修改默认的用户名的密码的方法也一样。
13 删除默认的用户名
我们一般的维护就这么多。
