把导出的备份数据传送到迁移的新服务器上

cd /home/oracle/gaotest/

scp -P 6022 ./*  root@192.168.35.178:/data/oracle/gaotest/oms  

cd cd /home/oracle/gaotest/

在新的服务器上创建数据库表空间，用户的等

1.OMS_lvnain01（数据文件大小2G）

create tablespace OMS_lvnain01 logging  datafile ‘/data/oracle/app/oracle/OMS_lvnain01.dbf‘ size 2000m autoextend on next 2000m maxsize unlimited;                                          ##这个表结构的OMS_lvnain01.dbf被我删除，但是内存不变

create user c##OMS_lvnain01 identified by OMS_lvnain01 default tablespace OMS_lvnain01;

grant connect,resource,dba to c##OMS_lvnain01;

==========

#drop tablespace OMS_lvnain01;
