简介
本文档介绍如何解锁Cisco IoT Field Network Director(IoT-FND)的Oracle用户帐户，并将密码到期设置更改为无限制。
先决条件
要求
Cisco 建议您了解以下主题：
- 基本Linux外壳操作（查看日志、启动进程等）
- 基本了解SQL查询
使用的组件
本文档不限于特定的软件和硬件版本。
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。
背景信息
本文档假设您有两台独立的Linux服务器：
问题
症状 1:IoT-FND未启动，数据库连接验证失败。
[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.
症状 2:cgms_db_connection_test.log包含类似于的条目：
[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
注意：IoT-FND应用使用CGMS_DEV数据库用户访问Oracle数据库。
注意： 默认情况下，Oracle数据库启用了密码到期，因此，在一段时间后，帐户密码将过期，如果不更改密码，就无法使用这些密码。
症状 3:Oracle CGMS_DEV用户帐户状态设置为“已过期”。
[oracle@IoT-FND-Oracle]$ sqlplus / as sysdba

SQL> SELECT USERNAME,ACCOUNT_STATUS FROM DBA_USERS WHERE USERNAME LIKE 'cg%';
USERNAME
--------------------------------------------------------------------------------
ACCOUNT_STATUS

CGMSDBA
OPEN
CGMS_DEV
EXPIRED
解决方案
步骤1.使用SSH登录IoT-FND服务器。
步骤2.停止FND服务。
[root@IoT-FND-SRV]$ service cgms stop
注意：如果不停止IoT-FND服务，FND将尝试使用旧密码连接到数据库，在完成此过程之前，帐户将被阻止。
步骤3.使用SSH登录Oracle服务器。
步骤4.切换到oracle系统用户：
[root@IoT-FND-Oracle]$ su - oracle
[oracle@IoT-FND-Oracle]$
步骤5.以sysdba用户身份连接到Oracle数据库的根实例：
[oracle@IoT-FND-Oracle]$ sqlplus / as sysdba

SQL>
步骤6.将password_life_limit设置修改为无限制：
sql> ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;
Profile altered.
步骤7.检查哪些帐户的密码已过期。
SQL> SELECT USERNAME,ACCOUNT_STATUS FROM DBA_USERS WHERE ACCOUNT_STATUS='EXPIRED';
USERNAME
--------------------------------------------------------------------------------
ACCOUNT_STATUS
--------------------------------
CGMSDBA
OPEN
CGMS_DEV
EXPIRED
步骤8.为CGMS_DEV用户设置密码：
sql> ALTER USER CGMS_DEV IDENTIFIED BY
;
User altered.
注意：如果您知道旧密码，可以重用它。如果否，则需要在IoT-FND服务器上运行cgmsSetup.sh脚本，以修改FND中设置的数据库密码。
步骤9.解锁CGMS_DEV用户帐户：
SQL> ALTER USER CGMS_DEV ACCOUNT UNLOCK;
User altered.
步骤10.验证CGMS_用户的帐户状态：
SQL> SELECT USERNAME,ACCOUNT_STATUS FROM DBA_USERS WHERE USERNAME LIKE 'cg%';
USERNAME
--------------------------------------------------------------------------------
ACCOUNT_STATUS
--------------------------------
CGMSDBA
OPEN
CGMS_DEV
OPEN
步骤11.使用SSH登录IoT-FND服务器。
步骤12.启动/opt/cgms/bin/setupCgms.sh脚本以更改数据库密码设置。保留所有其他设置的默认值：
[root@IoT-FND-SRV]# /opt/cgms/bin/setupCgms.sh

步骤13.检验数据库连通性：
[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: INFO: IoT-FND database connection verified.

步骤14.启动IoT-FND应用：
[root@IoT-FND-SRV ~]# service cgms start
步骤15.检验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.
