导出数据库
导出
1、创建目录 sqlplus / as sysdba create directory dbDir as d:\oralce_sdic_backup\; grant read,write on directory dbDir to sdic; 2、cmd导出 expdp sdic/hymake528sdic schemas=sdic dumpfile=oralce_sdic_backup_%date:~0,4%%date:~5,2%%date:~8,2%.dmp logfile=oralce_sdic_backup_%date:~0,4%%date:~5,2%%date:~8,2%.log directory=dbDir 导入 1、删除原用户、表空间 sqlplus / as sysdba; drop user sdic cascade; drop tablespace sdic_tablespace including contents and datafiles; 2、创建用户、表空间 sqlplus / as sysdba create tablespace sdic_tablespace datafile E:/soft/oracle11g_data/sdic1.dbf size 10g autoextend on next 5m; alter tablespace sdic_tablespace add datafile E:/soft/oracle11g_data/sdic2.dbf size 10g autoextend on next 5m; create user sdic identified by hymake528sdic; grant connect,resource,dba to sdic; alter user sdic default tablespace sdic_tablespace; 3、创建目录 create directory dbDir as E:\soft\oracle11g_bak; grant read,write on directory dbDir to sdic; 4、cmd导入
     impdp sdic/hymake528sdic DIRECTORY=dbDir DUMPFILE=ORALCE_SDIC_BACKUP_20171207.DMP REMAP_SCHEMA=sdic:sdic REMAP_TABLESPACE=USERS:sdic_tablespace table_exists_action=append full=y logfile=imp20171207.log

说明:
1、导出的dumpfile=oralce_sdic_backup_%date:~0,4%%date:~5,2%%date:~8,2%.dmp logfile=oralce_sdic_backup_%date:~0,4%%date:~5,2%%date:~8,2%.log
 
%date:~0,4%%date:~5,2%%date:~8,2%这里是取时间yyyyMMdd的方法。
2、
alter tablespace sdic_tablespace add datafile ‘E:/soft/oracle11g_data/sdic2.dbf‘ size 10g autoextend on next 5m;
  这是追加了一个数据库文件,当数据库大于32g的时候,一个数据库文件存放不下。
3、删除用户失败处理

  ////如果出现 ORA-00604: 递归 SQL 级别 1 出现错误
  ////或出现ORA-01940:无法删除当前连接的用户
  ////就重启数据库再drop
  ////SQL> shutdown immediate
  ////SQL> startup
