Oracle cloud control 12c 如何修改sysman密碼，12csysman

Oracle cloud control 12c 如何修改sysman密碼，12csysman
    前陣子在虛擬機器部署了Oracle Cloud Control 12c，事別幾日，竟然忘記了登陸密碼。主要是因為現在的Oracle有關的Software比之前提供更強的安全機制。什麼簡單的"oracle"之類的pwd不再支援了。這不過一陣子就搞忘了。這年頭的，賬戶多，密碼多，就是米不多，哈哈。。。下面說說其解決辦法吧。

一、emctl命令
emctl命令想必大家都見過，DB console時代經常會用到，現在功能是越來越強大了，下面僅僅列出有關修改pwd的部分
emctl config oms -change_repos_pwd [-old_pwd <old_pwd>] [-new_pwd <new_pwd>] [-use_sys_pwd [-sys_pwd <sys_pwd>]] 
Note: Steps in changing Enterprise Manager Root (SYSMAN) password are:
      1) Stop all the OMSs using 'emctl stop oms'
      2) Run 'emctl config oms -change_repos_pwd' on one of the OMS
      3a) Restart AdminServer and all the OMSs using 'emctl stop oms -all' and 'emctl start oms'
      3b) If BI Publisher is installed, restart the BI Publisher managed server(s) named 'BIP####'

二、修改步驟
下面簡要列出一下其修改步驟：
1) Stop OMS (leaving the Admin Server up)
2) Modify SYSMAN password
3) Stop all OMS components
4) Start OMS
5) Login to Oracle EMCC-12c with the new password

三、修改sysman登陸密碼

Enterprise Manager Base Platform - Version 12.1.0.1.0 and later
Information in this document applies to any platform.
GOAL

This article provides steps for modifying the password of SYSMAN and other Enterprise Manager users at the OMS/WLS level and the Repository database in a Cloud Control setup. 
Simply changing the password in the repository database is not sufficient as the password is also stored in the WLS credential store. The OMS uses sysman account to login into the repository database and if there is a mis-match in the password at the database level and the OMS configuration, the OMS cannot start and function properly.

For steps to follow in the earlier Enterprise Manager versions, refer to:
Note 270516.1: How to Change the Password of SYSMAN User in 10g and 11g Grid Control?

Note:

From 12c onwards, directly modifying the password for sysman or any other repository user at the Repository Database is not recommended.
Hence, ensure that the passwords are changed only using one of the below listed methods.
SOLUTION

If the current SYSMAN password is known

1. Stop all the OMS:

cd <OMS_HOME>/bin
emctl stop oms
Execute the same command on all the OMS machines including the primary OMS machine. Do not include '-all' as the Admin Server needs to be up during this operation.

2. Modify the SYSMAN password:

cd <OMS_HOME>/bin
emctl config oms -change_repos_pwd

Note: 

- The above command will prompt you for the current password of the SYSMAN user and the new password.
- The password will be modified at the Repository Database as well as the WLS Credential store and the monitoring credentials for the 'OMS and Repository' target.
- Along with the SYSMAN password, this command will modify the password for the EM users (SYSMAN_MDS, BIP, SYSMAN_OPSS, SYSMAN_APM, SYSMAN_RO) created in the Repository Database.

Example output:

emctl config oms -change_repos_pwd
Oracle Enterprise Manager Cloud Control 12c Release 12.1.0.1.0
Copyright (c) 1996, 2011 Oracle Corporation. All rights reserved.
Enter Repository User's Current Password :
Enter Repository User's New Password :

Changing passwords in backend ...
Passwords changed in backend successfully.
Updating repository password in Credential Store...
Successfully updated Repository password in Credential Store.
Restart all the OMSs using 'emctl stop oms -all' and 'emctl start oms'.

Successfully changed repository password.

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

cd <OMS_HOME>/bin
emctl stop oms -all
emctl start oms
If the current SYSMAN password is unknown

1. Stop all the OMS:

cd <OMS_HOME>/bin
emctl stop oms
Execute the same command on the primary OMS machine as well. Do not include '-all' as the Admin Server needs to be up during this operation.

If the version of OMS is 12.1.0.1 and if the password has been manually changed at the Database level, apply the Patch 13697830 to the OMS Home and then run the command below to get the password updated in all configurations.
 
2. Modify the SYSMAN password:

cd <OMS_HOME>/bin
emctl config oms -change_repos_pwd -use_sys_pwd -sys_pwd <sys user password> -new_pwd <new sysman password>
Note:

- The '-use_sys_pwd' is used to connect to the database as a SYS user and modify the sysman password in the Repository database.
-  The current sysman password is not prompted for and only the new password needs to be entered. This will allow the reset of the old password to the new password entered.
- The password will be modified at the Repository Database as well as the WLS Credential store and the monitoring credentials for the 'OMS and Repository' target.
- Along with the SYSMAN password, this command will modify the password for the EM users (SYSMAN_MDS, BIP, SYSMAN_OPSS, SYSMAN_APM, SYSMAN_RO) created in the Repository Database.

Example output:

emctl config oms -change_repos_pwd -use_sys_pwd -sys_pwd oracle123 -new_pwd oracle12
Oracle Enterprise Manager Cloud Control 12c Release 12.1.0.1.0

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

cd <OMS_HOME>/bin
emctl stop oms -all
emctl start oms

Known Issues

1. Problem: Modifying the sysman password fails with "java.io.IOException":

cd <OMS_HOME>/bin
emctl config oms -change_repos_pwd
Oracle Enterprise Manager Cloud Control 12c Release 12.1.0.1.0
Copyright (c) 1996, 2011 Oracle Corporation. All rights reserved.
Enter Repository User's Current Password :
Enter Repository User's New Password :
java.io.IOException
Error occurred. Check the log
Cause: The above error occurs if the Admin server is not running when the sysman password is being modified.
Solution: As advised in the sections above, the Admin Server needs to be up and running when the sysman password is being modified. So, the OMS should not be stopped using 'emctl stop oms -all'.

cd <OMS_HOME>/bin
emctl start oms
emctl stop oms
emctl config oms -change_repos_pwd

問怎查看oracle中sysman口令，注意是查看查看查看查看查看不是更改

如能查看密碼，那還有什麼安全性？
sysman在安裝時設定，估計和你的sys的口令是一樣的，
否則就是你沒有設定，使用sys登陸然後重設sysman密碼即可
 
oracle 12c怎進入圖形介面，也就是企業管理器，11g有manger console,12c不見了，幫幫忙

1、啟動EM Database Express 12c，設定連接埠即可啟用EM Express
SQL> show parameter dispatchers
SQL> exec DBMS_XDB_CONFIG.setHTTPPort(8080);

2、安裝Oracle Enterprise Manager Cloud Control 12c.
