我们创建一个lewen表空间，lewen用户，用于风哥本套课程后续环境中的练习：
我的环境是：Oracle 12c/19c for Linux x86_64，在操作系统用root登录：

#su - oracle
sqlplus "/as sysdba"
create tablespace lewen datafile '/data/oracle/oradata/orcl/lewen.dbf' size 100m autoextend off;
create user lewen identified by lewen default tablespace lewen;
grant connect,dba to lewen;
conn lewen/lewen;


#删除
drop tablespace lewen;

[root@MongoDB-01 ~]# ls /data/oracle/oradata/orcl/lewen.dbf -lh
-rw-r----- 1 oracle oinstall 101M Mar 20 20:42 /data/oracle/oradata/orcl/lewen.dbf
