手工建立oracle复制数据库

测试oracle streams之前先从源库通过手动物理备份，生成目的库。在作这个测试的时候，一直悲剧不断，刚开始的时候因为我的两个数据库的版本不一样，源是10.2.0.4，目的是10.2.0.5，在执行恢复

的时候提示是完成了，但是数据库就是不能打开，报ORA-01110错误,最后把源的版本也升级到10.2.0.5就正常了。

1，首先在源库登录数据库，并操作如下：
[oracle@rac1 gbk]$ sqlplus /nolog

SQL*Plus: Release 10.2.0.5.0 - Production on Thu Dec 30 10:04:20 2010

由于源库是新建立的，在建的过程中没有启动归档，故报此错误。

这是在源库的所有操作剩下的就要全部在目的库上操作了。不过要先把备份的控制文件、归档日志和参数文件也scp到目的数据库服务器上。

2，通过源库的spfile文件备份，创建pfile；
SQL>startup nomount pfile='/tmp/pfilebak.ora'
ORACLE 例程已经启动。

至此恢复完成。数据库正常，下一步就要开始测试，oracle streams了！
