Solaris 10下遷移10G RAC (七)

最近做了一個rac資料庫的遷移，中間涉及到很多部分內容，包括rac環境的搭建、ASM的設定、資料庫的遷移、升級等。
本文是這次遷移工作的第七部分：後續工作。

後續工作

修改db_name

為了與正式系統區分，需要修改還原過來的資料庫名稱。在rac中修改db_name的步驟與單例項步驟差不多，主要是要修改一些與cluster相關的引數。

停止所有例項，然後把其中一個例項啟動到mount狀態下：

SQL> startup mount

Database mounted.

SQL> exit

bash-3.00$ nid target=sys/testpass dbname=pretrade logfile=~/nid2.log

重新把cluster_database設定為true，並把db_name引數修改為新的名稱：

bash-3.00$ sqlplus "/as sysdba"

最後在開啟的時候open resetlogs即可。
