由于sys用户密码于orapwd文件不一致导致的ora-03113错误

冷备恢复了一个数据库，其他相关的配置文件均使用原来已存在，包括orapwd密码文件。 在起库时报密码文件不一致，不予理会，继续open数据库，如下：

SQL> startup

ORACLE instance started.

Total System Global Area  633999036 bytes

Fixed Size                   102076 bytes

ORA-01991: invalid password file

'/stg/oracle/8i/app/oracle/product/8.1.7/dbs/orapworacle'

SQL> alter database open;

Database altered.

但是当调用sys下的对象时出现3113错误。

SQL> exec sys.testuser_pwd_prc('hr','test1234');

begin sys.testuser_pwd_prc('hr','test1234'); end;

ORA-03113: end-of-file on communication channel

重新生成密码文件： 
orapwd file=orapworacle password=oracle8i

问题解决：
SQL> exec sys.testuser_pwd_prc('hr','test1234');
 
CHANGE  hr's password  successfull !
