<b>通常要遷移一個資料庫，我們會使用</b>
<b>1 冷備份，整個資料庫遷移，</b>
<b>2 rman duplicate 功能進行複制到本機或者複制到異機，</b>
<b>前面兩種都必須先在目标庫上安裝軟體。這裡測試另外一種方法：</b><b>對于單執行個體資料庫，複制整個oracle 10g 資料庫到另一個伺服器，relink 之後可以重新使用。。</b>
<b>檢視源庫資料庫庫檔案在$oracle_base 目錄下的分布：</b>

===========遇到的問題============
<b>第一次啟動的時候遇到ora-00205：</b>
sql> startup pfile='/tmp/initorcl.ora';
<b>ora-00205: error in identifying control file, check alert log for more info</b>
檢查告警日志檔案，發現如下錯誤：
errors in file /opt/oracle/admin/orcl/udump/orcl_ora_705.trc:
ora-00313: open failed for members of log group 1 of thread 1
ora-00312: online log 1 thread 1: '/opt/oracle/oradata/orcl/redo01.log'

<b>linux-x86_64 error: 2: no such file or directory</b>

提示沒有對應的檔案或者目錄。
檢視資料檔案，發現拷貝的時候是拷貝到/opt/oracle/ 目錄下的而不是/opt/oracle/orcl 目錄下，将資料檔案移動到orcl目錄下
