　 --------------------------------------------------------------------------------

　 D:/oracle/product/10.2.0/oradata/orcl/system01.dbf

　 D:/oracle/product/10.2.0/oradata/orcl/undotbs01.dbf

　 It means that your data files are placed in the directory D:/oracle//oradata/orcl/

　 The results you may see under Linux are as follows:

　 SQL> select name from v$datafile;

Create tablespace

We can start creating database tablespaces. Tablespace name: ATMV

    Drop tablespace and all contents in
    tablespace drop tablespace ATMV INCLUDING CONTENTS;
    create tablespace, specify data file, initialize 100M and increase by 50M

windows：
create tablespace ATMV datafile 'D:/oracle/product/10.2.0/oradata/orcl/ATMV.dbf' size 100m autoextend on next 50m maxsize unlimited;

Linux：

create tablespace ATMV datafile '/oracle/product/10.2.0/oradata/orcl/ATMV.dbf' size 100m autoextend on next 50m maxsize unlimited;

create user

Next we start to create a user, username ca, password ps

Delete the user and all objects under the user, pay attention to the keyword cascade

drop user ca cascade;

Create user:

　 create user ca identified by ps default tablespace ATMV;

Modify user permissions

　 grant role1, role2 to username;

　 An example is as follows:

　 grant dba, connect to wbppcs;

　　For specific user permission issues, please refer to the permission rules Personal learning records
