SQL> set linesize 1000
SQL> create user user_pass identified by "password" ;
User created.
SQL> alter user user_pass PASSWORD  expire;
User altered.
SQL> select username,ACCOUNT_STATUS from dba_users where username='USER_PASS';
USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
USER_PASS                      EXPIRED
SQL> select dbms_metadata.get_ddl('USER', username) || ';' usercreate from dba_users where username='USER_PASS';

      DEFAULT TABLESPACE "USERS"
      TEMPORARY TABLESPACE "TEMP"
      PASSWORD EXPIRE;
SQL> ALTER USER "USER_PASS" IDENTIFIED BY VALUES 'S:1E268627E76ACBE2A0C750D4FF86C6685514BEE0656BABDA251615E2E9BD;FDFAC641632E49E9';

Privileges of deployment user

If you have deployment user, after this user creates new table, you have DML procesess in new table. Create role for deployment user, grant privileges to this role because deployment user may not grant/revoke  to/from yourself.

For Example:
oracle@dbatest> sqlplus / as sysdba
SQL> create user kapsul identified by kapsul;
User created.
SQL> grant connect,resource to kapsul;
Grant succeeded.
SQL> GRANT GRANT ANY OBJECT PRIVILEGE TO KAPSUL;
Grant succeeded.
SQL> grant CREATE ANY TABLE to kapsul;
Grant succeeded.
SQL> create role role_kapsul;
Role created.
SQL> grant role_kapsul to kapsul;
Grant succeeded.

oracle@dbatest> sqlplus kapsul/kapsul

SQL> create table scott.kapsul_table (sayi number);
