前阵子在虚拟机部署了Oracle Cloud Control 12c，事别几日，竟然忘记了登陆密码。主要是因为现在的Oracle有关的Software比之前提供更强的安全机制。什么简单的"oracle"之类的pwd不再支持了。这不过一阵子就搞忘了。这年头的，账户多，密码多，就是米不多，哈哈。。。下面说说其解决办法吧。

Successfully changed repository password.

3. Stop the Admin server on the primary OMS machine and re-start all the OMS:

NOTE:1511014.1 - 12c: After changing the SYSMAN password directly into the DB, OMS status shows "Connection to the repository failed. Verify that the repository connection information provided is correct"
