Oracle数据库整体转移攻略
复制或迁移方法及步骤如下：在转移之前先卸载原先安装的Oracle（如果有的话）1、复制原 ORACLE 的安装目录到新机器或系统中的安装
复制或迁移方法及步骤如下：
在转移之前先卸载原先安装的Oracle（如果有的话）
1、复制原 ORACLE 的安装目录到新机器或系统中的安装目录，注意目录要一致，，盘符也要一致。
2、如果 ORACLE 的安装目录不在 Program Files 系统文件夹下，则需把原系统中的 Program Files 文件夹下的ORACLE 目录也复制到新系统的 Program Files 文件夹中去。
3、导出原系统中的 ORACLE 的注册表信息，主要有以下几个：
A. HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE
B. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services 下有关 ORACLE 的所有键。
通常包括以下 9 个 ——
\OracleMTSRecoveryService
\OracleOraHome92Agent
\OracleOraHome92ClientCache
\OracleOraHome92HTTPServer
\OracleOraHome92PagingServer
\OracleOraHome92SNMPPeerEncapsulator
\OracleOraHome92SNMPPeerMasterAgent
\OracleOraHome92TNSListener
\OracleServiceORA8
4、如果有多个数据库，注册表服务键下的 OracleServiceXXX 就会有多个。其中最主要的有监听服务和数据库服务就行了，即 OracleOraHome92TNSListenerXXX 和 OracleServiceXXX。
5、将导出的所有注册表的在新的系统中导入（注册）。
6、修改oralce\ora92\network\ADMIN\listener.ora中的ip地址（如果主机ip发生改变的话）。
7、设置系统环境变量，打开"我的电脑"的"属性"界面，在"高级"而点击"环境变量"进入设置，找到 [Path] 系统变量项目，点"编辑"，在变量值的输入框的最后，加入";ORACLE的安装目录"和";ORACLE的安装目录\bin"。
8、最后别忘了进入 C:\Documents and Settings\All Users\Start Menu\Programs 下把 Oracle - OraHome92 和 Oracle Installation Products 两个菜单文件夹也复制到新系统中，这个就和你新安装的一样了。然后重启系统（机器）[可选]，大功告成。
