关注以下几个参数
- EXTENT_SIZE，数据文件使用的簇大小，即每次分配新的段空间时连续的页数。只能是 16 页或 32 页或 64 页之一，缺省使用 16 页。
- PAGE_SIZE，数据文件使用的页大小，可以为 4 KB、8 KB、16 KB 或 32 KB 之一，选择的页大小越大，则 DM 支持的元组长度也越大，但同时空间利用率可能下降，缺省使用 8 KB。
- CASE_SENSITIVE，标识符大小写敏感，默认值为 Y 。当大小写敏感时，小写的标识符应用双引号括起，否则被转换为大写；当大小写不敏感时，系统不自动转换标识符的大小写，在标识符比较时也不区分大小写，只能是 Y、y、N、n、1、0 之一。
- CHARSET/UNICODE_FLAG，字符集选项。0 代表 GB18030；1 代表 UTF-8；2 代表韩文字符集 EUC-KR；取值 0、1 或 2 之一。默认值为 0。
- LENGTH_IN_CHAR，VARCHAR类型是否以字符为单位， 默认字节为单位，Y/N, 1/0。
- SYSDBA_PWD，SYSDBA用户密码，默认为
SYSDBA。 - SYSAUDITOR_PWD，SYSAUDITOR用户密码，默认为
SYSAUDITOR。 - DB_NAME，数据库名，默认为
DAMENG - INSTANCE_NAME，实例名，默认为
DMSERVER - PORT_NUM，监听端口，默认
5236
1.如果使用 docker 容器里面的 disql，进入容器后，先执行 source /etc/profile 防止中文乱码。
2.新版本 Docker 镜像中数据库默认用户名/密码为 SYSDBA/SYSDBA001。
