export NLS_LANG=american_america.AL32UTF8
create or replace directory dmp as '/tmp';
select * from dba_directories;
grant read,write on directory dmp to xxx;
expdp xxx/xxx dumpfile=xxx.dmp logfile=expdp.log directory=dmp;

impdp xxx/xxx dumpfile=baseline.dmp directory=dmp logfile=impdp.log

impdp xxx/xxx remap_schema=baseline:kin dumpfile=baseline.dmp directory=dmp logfile=impdp.log

impdp xxx/xxx remap_schema=baseline:kin dumpfile=baseline.dmp directory=dmp content=metadata_only logfile=impdp.log

命令:
EXPDP:
expdp jay/jay TABLES=[TABLE NAME]:[PARTITION NAME],[TABLE NAME]:[PARTITION NAME] PARALLEL=2 \
DUMPFILE=partial_partition.dmp DIRECTORY=dmp [CONTENT=DATA_ONLY] LOGFILE=expdp_partition.log


IMPDP:
impdp kin/kin directory=dmp REMAP_SCHEMA=jay:kin DUMPFILE=partial_partition.dmp TABLE_EXISTS_ACTION=APPEND \
CONTENT=DATA_ONLY LOGFILE=impdp_partition.log


部分参数说明:
PARALLEL
#任务并行数量,根据系统繁忙及服务器配置决定。


DUMPFILE
DUMP_%u.dmp   
#%U用于扩展导出的文件名。开启并行时，建议开启此参数值。
REMAP_SCHEMA
REMAP_SCHEMA=JAY:KIN


REMAP_TABLESPACE
REMAP_SCHEMA=SOURCE TABLESPACE:TARGET TABLESPACE
#针对表空间名称不同情况


TABLE_EXISTS_ACTION={SKIP|APPEND|TRUNCATE|REPLACE}
TABBLE_EXISTS_ACTION=APPEND
# APPEND 追加数据
# TRUNCATE 截断表
# REPLACE 删除新建表


CONTENT={ALL | DATA_ONLY | METADATA_ONLY}
CONTENT=DATA_ONLY
# ALL 所有内容
# DATA_ONLY 数据
# METADATA_ONLY 对象定义


INCLUDE=TABLE:\"IN \(\'JAY\', \'KIN\'\)\" 
#排除对象


PARFILE
#参数文件
#如命令较多转义字符，考虑使用参数文件形式

如cat expdp.par
