这篇文章主要讲解了“Oracle怎么修改数据库名称”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习“Oracle怎么修改数据库名称”吧！

1.关闭监听，正常关闭Oracle

[oracle@node3 ~]$ lsnrctl stop

LSNRCTL for Linux: Version 11.2.0.4.0 - Production on 19-FEB-2019 09:35:04

Copyright (c) 1991, 2013, Oracle. All rights reserved.

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521)))

The command completed successfully

SQL> shutdown immediate

Database closed.

Database dismounted.

ORACLE instance shut down.

2.重启数据库到mount状态

SQL> startup mount force

ORACLE instance started.

Total System Global Area 2.1379E+10 bytes

Fixed Size 2262656 bytes

Variable Size 2.0401E+10 bytes

Database Buffers 939524096 bytes

Redo Buffers 36073472 bytes

Database mounted.

3.nid修改数据库名称

nid target=sys/xxx dbname=BDDEV1 logfile=nid_0219.log

查看日志文件：

[oracle@node3 ~]$ more nid_0219.log

DBNEWID: Release 11.2.0.4.0 - Production on Tue Feb 19 09:33:15 2019

Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.

Connected to database BDDEV2 (DBID=2430401913)

Connected to server version 11.2.0

Control Files in database:

/opt/app/oracle/oradata/BDDEV1/control01.ctl

/opt/app/oracle/fast_recovery_area/BDDEV1/control02.ctl

Changing database ID from 2430401913 to 2391707803

Changing database name from BDDEV2 to BDDEV1

Control File /opt/app/oracle/oradata/BDDEV1/control01.ctl - modified

Control File /opt/app/oracle/fast_recovery_area/BDDEV1/control02.ctl - modified

Datafile /opt/app/oracle/oradata/BDDEV1/system01.db - dbid changed, wrote new name

Datafile /opt/app/oracle/oradata/BDDEV1/sysaux01.db - dbid changed, wrote new name

Datafile /opt/app/oracle/oradata/BDDEV1/undotbs01.db - dbid changed, wrote new name

Datafile /opt/app/oracle/oradata/BDDEV1/users01.db - dbid changed, wrote new name

Datafile /opt/app/oracle/oradata/BDDEV1/tbs_soe.db - dbid changed, wrote new name

Datafile /opt/app/oracle/oradata/BDDEV1/temp01.db - dbid changed, wrote new name

Control File /opt/app/oracle/oradata/BDDEV1/control01.ctl - dbid changed, wrote new name

Control File /opt/app/oracle/fast_recovery_area/BDDEV1/control02.ctl - dbid changed, wrote new name

Instance shut down

Database name changed to BDDEV1.

Modify parameter file and generate a new password file before restarting.

Database ID for database BDDEV1 changed to 2391707803.

All previous backups and archived redo logs for this database are unusable.

Database is not aware of previous backups and archived logs in Recovery Area.

Database has been shutdown, open database with RESETLOGS option.

Succesfully changed database name and ID.

DBNEWID - Completed succesfully.

如果日志文件中有报错信息，比如：NID-00135: There are 1 active threads，则可能是因为没有正常关闭数据库导致的。

4.修改参数文件中db_name后，启动Oracle

SQL> startup nomount

ORACLE instance started.

Total System Global Area 1185853440 bytes

Fixed Size 2252664 bytes

Variable Size 436207752 bytes

Database Buffers 738197504 bytes

Redo Buffers 9195520 bytes

SQL> alter system set db_name=BDDEV1 scope=spfile;

System altered.

SQL> shutdown immediate

ORA-01507: database not mounted

ORACLE instance shut down.

SQL> startup mount

ORACLE instance started.

Total System Global Area 1185853440 bytes

Fixed Size 2252664 bytes

Variable Size 436207752 bytes

Database Buffers 738197504 bytes

Redo Buffers 9195520 bytes

Database mounted.

resetlogs方式打开数据库：

SQL> alter database open resetlogs;

Database altered.

5.打开监听

lsnrctl start
