oracle数据库备份还原
------------------------备份------------------------------
一、全备份
导出整个数据库, 命令
exp 用户名/密码@服务名 file=文件全路径 full=y
------------------------还原------------------------------
一、环境设置
1。新建数据库或选择已经存在的数据库。
2。新建表空间wzgis，给足够大的空间，最好分文件存放。
在还原之前确保mapgisdba和cadadba两个用户已经存在并且权限正确
3。新建表空间mapgisdba，如果数据库通过mapgis创建过管理过程，可以跳过该步骤和4、5步
4。新建mapgisdba用户，位于表空间mapgisdba上
5。给mapgisdba用户赋权，执行一下脚本
GRANT ANALYZE ANY TO "MAPGISDBA" WITH GRANT OPTION;
GRANT CREATE ROLE TO "MAPGISDBA" WITH GRANT OPTION;
GRANT CREATE TABLESPACE TO "MAPGISDBA" WITH GRANT OPTION;
GRANT CREATE USER TO "MAPGISDBA" WITH GRANT OPTION;
