GBase 8a集群数据库用户密码长度限制,通过系统参数password_min_length进行。

gbase> show variables like '%password%';
+------------------------------+-------+
| Variable_name | Value |
+------------------------------+-------+
| _gbase_check_password_format | OFF |
| old_passwords | OFF |
| password_format_option | 0 |
| password_life_time | 0 |

修改所有管理节点和计算节点的配置文件,增加
password_min_length=8
参数,重启集群所有节点
