SQL> conn / as sysdba//作为sysdba登录
Connected to an idle instance.
SQL> startup //启动startup，1、shutdown normal 正常方式关闭数据库。 2、shutdown immediate 立即方式关闭数据库。 在SVRMGRL中执行shutdown immediate，数据库并不立即关闭， 而是在Oracle执行某些清除工作后才关闭（终止会话、释放会话资源）， 当使用shutdown不能关闭数据库时，shutdown immediate可以完成数据库关闭的操作。 3、shutdown abort 直接关闭数据库，正在访问数据库的会话会被突然终止， 如果数据库中有大量操作正在执行，这时执行shutdown abort后，重新启动数据库需要很长时间。

5.sqlplus创建表空间和临时表空间
SQL> create tablespace qc_data datafile '/usr/local/oracle/oradata/zh888/qc_data.dbf' size 200m autoextend on next 200m maxsize 1000m extent management local;
//创建qc_data名字的表，指定oracle数据库文件所在的目录，大小为200m，自动增加空间200m，最大为1000m如果1000m替换为unlimited就是无限制，最后为本地管理。
SQL> create temporary tablespace qc_temp tempfile '/usr/local/oracle/oradata/zh888/qc_temp.dbf' size 100m autoextend on next 100m maxsize 2000m extent management local;//创建临时表空间

GRANT select any table TO zh;
第一个是授予所有table有create权限,第三是授予所有table有select权限.
第二个就是赋予DBA的权限，这才是最重要的,其实只要第二就可以了.

20.删除用户表空间的步骤:
Alter tablespace 表空间名称 offline;
Drop tablespace 表空间名称;(表空间无有数据时用)
或者
drop tablespace 表空间名称 including contents;(表空间下有数据时候用)
temporary tablespace是oracle里临时表空间，临时表空间主要用途是在数据库进行排序运算、管理索引、访问视图等操作时提供临时的运算空间，当运算完成之后系统会自动清理。当oracle里需要用到sort的时候，而pga又没有足够大的时候，将会把数据放入临时表空间里进行排序，同时如果有异常情况的话，也会被放入临时表空间,但是我们需要重建temporary tablespace,直接是不能drop默认的临时表空间的，不过我们可以通过以下方法来做。查看目前的temporary tablespace
21.SQL> select name from v$datafile;//查看数据库表空间存放的路径。
