检查数据库版本：
select * from v$version;
检查下面参数，两个数据库必须保证一致，才能执行成功。
select SF_GET_PAGE_SIZE();-- 32768
select SF_GET_UNICODE_FLAG();-- 1
select SF_GET_CASE_SENSITIVE_FLAG();-- 1
select CASE_SENSITIVE();-- 查看大小写敏感(1-敏感;0-不敏感)
导出数据库文件成dmp文件：
1、进入达梦数据库安装目录的bin目录：例如，D:\dm8\bin
2、在地址栏中输入cmd命令，进入终端命令窗口。
3、执行导出命令：
dexpUSERID=SYSDBA/DaMeng123@localhost:5236SCHEMAS=RENRENFILE=RENREN_DATA_20260704.dmpLOG=RENREN_LOG_20260704.logDIRECTORY=E:/backup 下面语法： dexpUSERID=SYSDBA/密码@B的IP:5236SCHEMAS=模式名FILE=schema.dmpLOG=exp.logDIRECTORY=D:\backup导入dmp文件到数据库中（麒麟系统）
1、将上述导出的文件传输到麒麟系统中，传完文件后，在麒麟系统打开终端，切换到 dmdba 用户操作。
2、导入前先确认目标库里有没有同名模式：
有同名模式：直接执行下面的导入命令。
无同名模式：必须先手动建好表空间和用户，否则会报错。
