PL/SQL procedure successfully completed. Commit complete. BEGIN * ERROR at line 1: ORA-04063: package body "SYSMAN.MGMT_LOGIN_ASSISTANT" has errors ORA-06508: PL/SQL: could not find program unit being called: "SYSMAN.MGMT_LOGIN_ASSISTANT"
执行 SQL> alter package mgmt_login_assistant compile body;
此时会报错，继续查看出错原因：
SQL> show errors；
显示 函数ENCRYPT invalid。
这说明magmt_login_assistant这个包依赖ENCRYPT函数，而ENCRYPT函数自身有问题。那么继续看看ENCRYPT函数究竟什么问题。
SQL> alter function encrypt compile; Warning: Function altered with compilation errors. SQL> show errors; Errors for FUNCTION ENCRYPT: 9/5 PL/SQL: Statement ignored 10/22 PLS-00201: identifier 'SYS.UTL_I18N' must be declared
找到了错误根源，解决就容易多了，以sys账户登录，然后赋予public角色执行SYS.UTL_I18N这个包的权限。
SQL> grant execute on UTL_I18N to public; Grant succeeded.
SYSMAN.MGMT_LOGIN_ASSISTANT包 < SYSMAN.ENCRYPT函数 < SYS.UTL_I18N包。
然后退出sql，重新执行 emca -repos recreate。如果还是报错，请按照上面查找问题的思路解决问题，直到成功。

3.2 配置文件布局
使用emca -config dbcontrol db命令来创建必要的配置文件。这个操作一般不会出错，注意填正确各个账户的密码就可以了。[oracle@db001 ~]$ emca -config dbc
