Oracle數(shù)據(jù)庫中使用nid來修改數(shù)據(jù)庫名
作者：佚名
以下的文章主要介紹的是Oracle數(shù)據(jù)庫中正確使用nid來修改數(shù)據(jù)庫名的實際操作，以下就是具體方案的描述，希望在你今后的學(xué)習(xí)中會有所幫助。
某些系統(tǒng)是因為Oracle數(shù)據(jù)庫的名稱不是很規(guī)范，如果你不想對Oracle數(shù)據(jù)庫重新創(chuàng)建的話，你可以使用Oracle自帶的工具即nid來修改Oracle數(shù)據(jù)庫的名稱。在整個修改過程中，對控制文件和數(shù)據(jù)文件進行修改，且重置dbid，建議在修改前對數(shù)據(jù)進行備份。
在本例子中，我們將Oracle數(shù)據(jù)庫中的instance_name和db_name從“oratest”修改為“test”,數(shù)據(jù)庫版本為10.2.0.3。
查看數(shù)據(jù)庫信息。
- SQL> show parameter instance_name
- NAME TYPE VALUE
- stance_name string ORATEST
- SQL> show parameter db_name
- NAME TYPE VALUE
- db_name string ORATEST
- SQL>show parameter service_name
- NAME TYPE VALUE
- db_name string ORATEST
- SQL>select dbid from v$database;
- DBID
- 3213300265
修改前Oracle數(shù)據(jù)庫名為"oratest",dbid="3213300265"。接下來修改數(shù)據(jù)庫名稱，先停止數(shù)據(jù)庫，然后啟動到mount狀態(tài)下，使用nid工具修改dbname。
