ora-00988

本来想看下默认表空间的有效范围

CREATE bigfile TABLESPACE "USERS" DATAFILE
'/u01/oradata/orcl/users.dbf' SIZE 500M
AUTOEXTEND ON NEXT 20M
LOGGING ONLINE PERMANENT BLOCKSIZE 8192
EXTENT MANAGEMENT LOCAL AUTOALLOCATE SEGMENT SPACE MANAGEMENT AUTO;

alter database default tablespace users;

SQL> create user u1 identified by 1;
create user u1 identified by 1
                             *
ERROR at line 1:
ORA-00988: missing or invalid password(s)


SQL> create user u1 identified by u1;

User created.

写1就报错，写u1就不报错，何解？

Oracle10g对密码的要求如下：
系统用户（SYS、SYSTEM）口令长度不能小于7个字符
第一个字符不能为数字
且全部字符中应该为字母和数字混合

貌似11g就没这问题

是哪个参数控制的吧？
