oracle的expdp和impdp命令研究

--创建远程数据连接

create database link DB_MZDB11  connect to YTMZTWO identified by YTMZTWO909  using ‘MZDB11‘;

--创建本地目录

create directory db_mz as ‘c:‘;

--授权用户读写

grant read,write on directory db_mz to YTMZTWO,YTMZ;

--授权用户可以创建dblink

grant create database link to YTMZTWO,YTMZ;

grant resource to YTMZTWO;

--导出命令

expdp YTMZTWO/YTMZ2.2 schemas=YTMZTWO dumpfile=YTMZTWO.DMP directory=db_mz network_link=DB_MZDB11 logfile=log.log exclude=TABLE:\" IN \(\‘PUB_ATTACHMENT\‘,\‘PUB_SIGNSEAL\‘\)\"

--在配置文件中添加内容

ORCL_rxxc =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 61.139.100.204)(PORT = 1522))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = ORACLE)

)

)

--直接导入数据命令

impdp YTMZTWO/YTMZ2.2 directory=db_mz NETWORK_LINK=DB_MZDB11 schemas=YTMZTWO  logfile=log.log exclude=TABLE:\" IN \(\‘PUB_ATTACHMENT\‘,\‘PUB_SIGNSEAL\‘\)\"
