一、准备目标数据库 1、确保目标数据库的字符集 NLS_CHARACTERSET 和源数据库一致 select * from nls_database_parameters 2、创建要迁移数据库表空间 select tablespace_name from dba_tablespaces create tablespace BBGODB datafile '+DATA_VG' size 300m autoextend on 3、创建相应的schema create user BBGO identified by BBGO default tablespace BBGODB grant connect,resource to BBGO 4、创建目录并授权 mkdir /home/oracle/oracleDump sqlplus / as sysdba create or replace directory dump_dir as '/home/oracle/oracleDump'; grant read,write on directory dump_dir to BBGO; exit
二、导出源数据库的schema 1、创建目录并授权 mkdir /home/oracle/oracleDump sqlplus / as sysdba create or replace directory dump_dir as '/home/oracle/oracleDump'; grant read,write on directory dump_dir to BBGO; exit 2、导出数据 expdp "'/ as sysdba'" schemas=BBGO dumpfile=expdp.dmp DIRECTORY=dump_dir logfile=BBGO.log compression=all
三、将数据导入到目标数据库中 impdp "'/ as sysdba'" directory=dump_dir dumpfile=expdp.dmp schemas=BBGO 注：如果schema不同，使用 remap_schema=BBGO:BBGOA 重新映射
