如何创建表空间?

create tablespace test logging datafile 'D:\oracle\oradata\orcl\test.ora' size 50m autoextend on next 50m  maxsize unlimited extent  management local;


如何创建用户?

create user username profile default default tablespace test;


如何给用户赋相应的权限?


grant dba,connect,resource to username;


如何往创建的表空间里导入dmp数据?

imp username/userpassword@orcl file=D:/oracle/oradata/some.dmp full=y ignore=y


相应的导出如何操作?

exp username/userpassword@orcl file=D:/oracle/oradata/outputdata.dmp owner=username


视图的使用?发生视图丢失???我完善的一个模块其中的bug就是因为视图的丢失

数据库视图丢失。


晚上11点,我的Oracle又发生了一些事情。过程是这样的

白天我的项目部署后显示的数据不完全,所以想回家重新导入数据。但是我把用户相关的删除之后,删不掉ora文件,所以我就到windows的服务里关闭了所有的Oracle服务,然后把相关的ora文件删除了。但是之后在登录重新创建表空间时,总是提示:ORA-01033:ORACLE initialization or shutdown in progresss即初始化或关闭正在进行中,登录不了。我启动Oracle服务也不行,还是报这个错误!重新启动也还是没有作用,还是不行。

20120717Oracle使用报错ora-01033 Oracle 初始化或关闭进行中

一下是网上搜索的文章,成功解决了这个问题

在此之前需要先连接上数据库

进入cmd命令模式,输入命令sqlplus /NOLOG

进入到sqlplus模式,然后connectOracle用到的命令是

SQL>connect sys/change_on_install as sysdba 

提示:已成功 

使用一下命令删除相应的文件就好了。
