使用impdp将源库下的部分数据 导入 到目标库中
源库上 按照schema导出
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
expdp system/oracle directory=EXPDP schemas=news dumpfile=20151227expnews.dmp logfile=20151227expnews.log
目标库上使用remap_schema导入
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
impdp system/oracle111 directory=EXPDP dumpfile=20151227expnews.dmp schemas=news remap_schema=news:kash remap_tablespace=paytbs:kash_tbs logfile=20151227impkash.log
使用impdp将一个用户下的部分表导入到目标库另一个用户下
源库上使用tables将需要导出的表以,号分开，导出
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
expdp system/oracle directory=EXPDP tables=news.CONFIG,news.CONFIG_LOG,news.APPLY,news.INFO dumpfile=20160104expnews4tables.dmp logfile=20160104expnews4tables.log
目标库上导入，使用remap_schema代替imp中的fromuser，touser选项，使用remap_tablespace来表示将导入的表创建在哪个新的表空间中
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
impdp system/oracle111 directory=EXPDP dumpfile=20160104expnews4tables.dmp tables=news.CONFIG,news.CONFIG_LOG,news.APPLY,news.INFO remap_schema=news:kash remap_tablespace=paytbs:kash_tbs logfile=20160104expnews4tables.log
使用impdp将源库一个表的部分数据导入到目标库中
源库上使用query语句 \为转义符，导出部分数据。
export LANG=AMERICAN_AMERICA.ZHS16GBK
expdp system/oracle directory=EXPDP tables=b.b_file query=\" WHERE file_id IN\(\'785\',\'786\',\'787\',\'788\',\'789\',\'790\',\'791\'\)\" dumpfile=20160104expdpb_file.dmp logfile=20160104expdpb_file.log
目标库上导入
export LANG=AMERICAN_AMERICA.ZHS16GBK
impdp system/oracle111 directory=EXPDP tables=b.b_file dumpfile=20160104expdpb_file.dmp TABLE_EXISTS_ACTION=APPEND logfile=20160104impdpb_file.log
【在远端直接导入】
expdp system/oracle directory=EXPDPBD dumpfile=rptest_1tablespace_20160520.dmp TABLESPACES=myts network_link='DBLINK_RP' logfile=rptest_1tablespace_20160520.log
源端：
RAN USERS
目标端
create tablespace mydemo datafile '/u01/app/oracle/oradata/ora11g/mydemo01.dbf' size 100M;
create user sender identified by oracle default tablespace mydemo;
grant connect,resource to sender;
需求：
将源端的ran用户下的表 导入到 本地的sender用户下。使用network_link参数
impdp system/oracle schemas=ran remap_schema=ran:sender remap_tablespace=users:mydemo,myts:mydemo network_link='DBLINK_RP' logfile=rptest_1tablespace_2016052001.log
[ora11g@instance ~]$ impdp system/oracle schemas=ran remap_schema=ran:sender remap_tablespace=users:mydemo,myts:mydemo network_link='DBLINK_RP' logfile=rptest_1tablespace_2016052001.log
