Oracle expdp跟expdp的使用
Oracle expdp和expdp的使用
1.同一个用户下的导入和导出 有的时候防止磁盘碎片可能需要的操作。 查看帮助:expdp -help impdp -help 创建目录 create directory data_pump_dir_scott as '目录的路径'; 备注一下采用默认的导出导入文件目录data_pump_dir; 查看目录 select * from dba_directories; set line 120; col owner for a6; col directory_name for a20; col directory_path for a65; select * from dba_directories; 授权目录 grant read,write on directory data_pump_dir to scott; grant create session ,exp_full_database,imp_full_database to scott; select count(1) from emp where job<> 'ANALYST' and sal>1250 参数文件scott_par.txt 内容如下: DIRECTORY=DATA_PUMP_DIR tables=(emp,dept) DUMPFILE=SCOTT.DMP QUERY=scott.emp:"where job<> 'ANALYST' and sal>1250 " 导出 expdp scott/tiger parfile=scott_par.txt drop table emp; drop table dept; 导入 impdp scott/tiger parfile=scott_par.txt 2.不同用户不同表空间之间移动 sqlplus /nolog conn scott/tiger set line 120; set pagesize 30; col object_name for a35; 查看用户对象 select object_name ,object_type,status from user_objects; select object_name ,object_type,status from user_objects where object_name not like 'BIN%'; 查看用户表对应的表空间 select table_name ,tablespace_name from user_tables; 查看用户索引和表空间的关系 col index_name for a20; col index_type for a20; col tablespace_name for a20; select index_name,index_type,tablepspace_name from user_indexes; 导出参数文件expdp_par.txt DIRECTORY=DATA_PUMP_DIR SCHEMAS=scott DUMPFILE=schema_scott.dat EXCLUDE=PACKAGE EXCLUDE=VIEW EXCLUDE=TABLE:"LIKE '%DUMP'" 导出 expdp scott/tiger parfile=expdp_par.txt 授权 sqlplus /nolog conn sys/ticket as sysdba grant read,write on directory data_pump_dir to jinfeng; grant create session ,exp_full_database,imp_full_database to jinfeng; impdp_par.txt内容如下: DIRECTORY=DATA_PUMP_DIR SCHEMAS=scott DUMPFILE=schema_scott.dat --导入的文件 REMAP_SCHEMA=SCOTT:JINFENG --导入用户的映射 REMAP_SCHEMA=USERS:TBS_DATA --导入表空间的映射 导入: impdp jinfeng/ticket parfile=impdp_par.txt 确认导入成功: sqlplus /nolog conn jinfeng/ticket select index_name ,tablespace_name from user_indexes; select table_name,tablespace_name from user_tables;
