簡介
本文檔介紹如何解鎖Cisco IoT Field Network Director(IoT-FND)的Oracle使用者帳戶，並將密碼到期設定更改為無限制。
必要條件
需求
思科建議您瞭解以下主題：
- 基本Linux shell操作（檢視日誌、啟動進程等）
- 對SQL查詢的基本瞭解
採用元件
本文件所述內容不限於特定軟體和硬體版本。
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。
背景資訊
本檔案假設您有兩個獨立的Linux伺服器：
問題
症狀1:IoT-FND未啟動，資料庫連線驗證失敗。
[root@IoT-FND-SRV ~]# service cgms status
IoT-FND Version X.X.XX
08-01-2018 15:14:58 CEST: INFO: IoT-FND database server: XX.XX.XX.XX
08-01-2018 15:15:01 CEST: ERROR: IoT-FND database connection verification failed.
08-01-2018 15:15:02 CEST: ERROR: IoT-FND application server is not running.
症狀2:cgms_db_connection_test.log包含類似以下內容的條目：
[root@IoT-FND-SRV ~]# tail -n 50 /opt/cgms/server/cgms/log/cgms_db_connection_test.log
2018-08-01 12:27:22,767:INFO:main:TestDBConnection: Checking database connection. Please wait ...
2018-08-01 12:27:22,856:INFO:main:TestDBConnection: Database URL: jdbc:oracle:thin:@XX.XX.XX.XX:1522:cgms
2018-08-01 12:27:22,856:INFO:main:TestDBConnection: Database user: cgms_dev
2018-08-01 12:27:23,156:ERROR:main:TestDBConnection: Unable to check database connection. Exception:
java.sql.SQLException: ORA-28001: the password has expired
附註：IoT-FND應用程式使用CGMS_DEV資料庫使用者訪問Oracle資料庫。
附註： 預設情況下，Oracle資料庫已啟用口令過期功能，因此一段時間後，帳戶口令會過期，如果不更改口令，將無法使用它們。
症狀3:Oracle CGMS_DEV使用者帳戶狀態設定為EXPIRED。
[oracle@IoT-FND-Oracle]$ sqlplus / as sysdba

CGMS_DEV
EXPIRED
解決方案
步驟1.使用SSH登入到IoT-FND伺服器。
步驟2.停止FND服務。
[root@IoT-FND-SRV]$ service cgms stop
註：如果不停止IoT-FND服務，FND將嘗試使用舊密碼連線到資料庫，帳戶將被阻止，直到您完成此過程。
步驟3.使用SSH登入Oracle伺服器。
步驟4.切換到oracle system user:
[root@IoT-FND-Oracle]$ su - oracle
[oracle@IoT-FND-Oracle]$
步驟5.以sysdba使用者身份連線到Oracle資料庫的根例項：
[oracle@IoT-FND-Oracle]$ sqlplus / as sysdba
SQL*Plus: Release 12.1.0.2.0 Production on Wed Aug 1 16:19:23 2018

SQL>
步驟6.將password_life_limit設定修改為無限制：
sql> ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;
Profile altered.
步驟7.檢查哪些帳戶的密碼已過期。
SQL> SELECT USERNAME,ACCOUNT_STATUS FROM DBA_USERS WHERE ACCOUNT_STATUS='EXPIRED';
USERNAME
--------------------------------------------------------------------------------
ACCOUNT_STATUS
--------------------------------
CGMSDBA
OPEN
CGMS_DEV
EXPIRED
步驟8.設定CGMS_DEV使用者的密碼：
sql> ALTER USER CGMS_DEV IDENTIFIED BY
;
User altered.
注意：如果您知道舊密碼，可以重複使用。如果不是，則您需要在IoT-FND伺服器上運行cgmsSetup.sh指令碼來修改FND中設定的資料庫密碼。
步驟9.解鎖CGMS_DEV使用者帳戶：
SQL> ALTER USER CGMS_DEV ACCOUNT UNLOCK;
User altered.
步驟10.驗證CGMS_使用者的帳戶狀態：
SQL> SELECT USERNAME,ACCOUNT_STATUS FROM DBA_USERS WHERE USERNAME LIKE 'cg%';
USERNAME
--------------------------------------------------------------------------------
ACCOUNT_STATUS
--------------------------------
CGMSDBA
OPEN
CGMS_DEV
OPEN
步驟11.使用SSH登入到IoT-FND伺服器。
步驟12.啟動/opt/cgms/bin/setupCgms.sh 指令碼更改資料庫密碼設定。保留所有其他設定及其預設值：
[root@IoT-FND-SRV]# /opt/cgms/bin/setupCgms.sh

步驟13.驗證資料庫連線：
[root@IoT-FND-SRV ~]# service cgms status
IoT-FND Version X.X.X-XXX
08-01-2018 16:46:14 CEST: INFO: IoT-FND database server: XX.XX.XX.XX

08-01-2018 16:46:15 CEST: ERROR: IoT-FND application server is not running.
步驟14.啟動IoT-FND應用程式：
[root@IoT-FND-SRV ~]# service cgms start
步驟15.驗證IoT-FND操作：
[root@IoT-FND-SRV ~]# service cgms status
IoT-FND Version X.X.X-XXX
08-01-2018 16:49:04 CEST: INFO: IoT-FND database server: XX.XX.XX.XX
08-01-2018 16:49:04 CEST: INFO: IoT-FND database connection verified.
08-01-2018 16:49:05 CEST: INFO: IoT-FND application server is up and running.
