select * from dba_data_files ; ---查看用来导数据库的数据库数据文件路径信息
 
 ----创建顺德一体化项目的数据库的对应的表空间。该数据库文件最少需要2个

*/


--创建用户 设置权限
create user SYNC_PLUS_1 identified by  SYNC_PLUS_1 default tablespace SYNC_PLUS_1 quota 500m on users;
----  这里第一个  TEST_SYNC  为用户名，第二个  TEST_SYNC  为密码，第三个  SYNC_PLUS_1 为表空间名。然后执行。
grant all privileges to   SYNC_PLUS_1;
--- 执行该语句给  TEST_SYNC  用户授权，此时  TEST_SYNC  用户就可以登录了。

---创建角色
create role  ALLINONE_JX ;
create role  ALLOUTSIDE ;
create role  ALLTAX ;
create role RDCX;

---给用户分配角色
grant ALLTAX  to sync_plus_1 ;
grant ALLINONE_JX  to sync_plus_1 ;
grant ALLOUTSIDE to sync_plus_1 ;
grant dba to sync_plus_1;
grant RDCX to sync_plus_1; 

---增加表空间的数据文件
alter tablespace  sync_plus_1 add   datafile
