1. 在quot;Configuration and Migration Toolsquot;中选择quot;Enterprise Manager Configuration Assistantquot;;创建quot

1. 在"Configuration and Migration Tools"中选择"Enterprise Manager Configuration Assistant";

创建"档案资料库":

(1) 配置本地OMS;

(2) 创建新的档案资料库;

(3) ★建议采用"自定义"方式(无需创建新数据库);

(4) "档案资料库放在何处?": 建议选择"在现有的其他数据库中";

(5) 以DBA身份的用户登录到数据库中, 其中"服务"项输入Oracle的SID;★【6688电子商务网站   】

2. 运行"Enterprise Manager Console", 并选择"登录到OMS";

管理员: sysman(默认)★

口  令: oem_temp(默认)★

ManagementServer: localhost或主机名

★注意: 登录之前确保OracleOraHome90ManagementServer服务已启动, 登录成功立即修改密码;

3. 成功登录OMS后, 使用"搜索向导"搜索结点, 以便显示数据库等结点项;

★注意: 搜索之前要确保racleOraHome90Agent服务已启动;

搜索的结点名称输入机器名或localhost;

4. 在OEM中单击数据库结点, 使用system/manager登录;

5. 在"配置"菜单中选择"首选项", 然后配置"首选身份证明";

(1) 选择第3步中搜索到的结点(机器名或localhost);

(2) 用户名: OS的登录名(目前我的登录名是: administrator)★

口  令: OS的登录密码

★注意: 必须在"控制面板"->"本地安全设置"->"本地策略"->"用户权利指派"->"作为批处理作业登录"

项目中添加OS登录名才可实现数据导出/导入.

[以上5步配置完成即可进行数据的导出与导入操作]

★注意: 以上配置对于数据的导出和导入操作可以正常进行;

如果选择数据库"备份管理"中的"备份"或"恢复操作时",

应采用sys/change_on_install以sysdba角色登录数据库服务器,

同时配置"首选身份证明"的数据库登录用户为: sys/change_on_install/sysdba;

否则无法进行备份与恢复操作.

--------------------------------------------------------------------------------------------

  使用命令行的方式导入/导出数据

--------------------------------------------------------------------------------------------

1. 运行CMD, 使用EXP命令导出数据;(注意: 导出的数据文件位于当前命令行所指示的路径下)

2. 使用IMP导入数据;

如果Scott用户无法导入数据(提示权限不足), 可使用system用户登录"Enterprise Manager Console",

赋予Scott用户DBA角色即可.

★注意: imp命令运行时提示输入的用户名和密码即为将要导入数据的目标用户;
