sysman登录oem页面报错如下：

查看oms状态：

cd <OMS_HOME>/bin emctl status oms -details

查看oms状态详细显示用户名密码不识别。

bug造成，修复：

SQL> update mgmt_audit_master set prepopulate_days=5 where prepopulate_days is null;

SQL> exec mgmt_audit_admin.add_audit_partition;

SQL> commit ;

如果当前SYSMAN密码不知道，修改密码：

1. Stop all the OMS: cd <OMS_HOME>/bin emctl stop oms
2. Modify the SYSMAN password: cd <OMS_HOME>/bin emctl config oms -change_repos_pwd

If the current SYSMAN password is unknown cd $OMS_HOME/bin emctl stop oms [oracle@hzem12c01 bin]$ ./emctl config oms -change_repos_pwd -use_sys_pwd -sys_pwd "oracle" -new_pwd "oracle123" 第一个为sys的密码，第二个为修改sysman的密码

emctl stop oms -all emctl start oms
