新手刚刚安装oracle创建数据库命令出ORA-01100: database already mounted

[ywasp]

怎么解决

[Andy__Huang]

Cause:
During ALTER DATABASE MOUNT, an attempt is being made to mount a database on an instance in which a database is or has previously been mounted.
Action:
If you wish to mount the database, shutdown the instance and then startup the instance and retry the operation.

oracle创建数据库实例不要用create database.....,
可以使用dbca来创建,就不会有问题了。

====================================
数据库已经创建好了吧

可以用Alter database Open来打开试试呢。

[范佩西_11]

Alter database Open；
或者
shutdown immediate;
startup;

[gdqsh]

对，要用dbca来建立数据库，如果还有问题，
你再跟帖
