create profile app_user limit sessions_per_user unlimited cpu_per_session unlimited cpu_per_call 3000 connect_time 45 logical_reads_per_session default logical_reads_per_call 1000 private_sga 15k composite_limit 5000000;
总的resource cost不超过五百万service units。计算总的resource cost的公式由alter resource cost语句来指定。
3．设置密码限制profile：
create profile app_users2 limit failed_login_attempts 5 password_life_time 60 password_reuse_time 60 password_reuse_max 5 password_verify_function verify_function password_lock_time 1/24 password_grace_time 10;
4．将配置文件分配给用户：
SQL> alter user dinya profile app_user;
用户已更改。
SQL> alter user dinya profile default;
