oracle EXPDP/IMPDP 常用命令

expdp/impdp官方文档：
http://docs.oracle.com/cd/E11882_01/server.112/e22490/dp_export.htm#SUTIL200

模糊匹配

impdp \'sys/sys123 as sysdba\'  directory=BACKUP_DIR network_link=link_sdtrace schemas=test  cluster=N 
 exclude=TABLE:\"LIKE \'T_E_TMP%\'\",TABLE:\"LIKE \'T_E100_P%\'\",TABLE:\"LIKE \'T_TEMP_PRODUCT%\'\",TABLE:\"LIKE \'%_BAK\'\",

带WHERE条件

expdp \'sys/xxxxx as sysdba \'  dumpfile=t1.dmp logfile=t1.log tables=SCOTT.T1   QUERY=SCOTT.T1:\"WHERE funnode=\'20110QUERY\'\"

某个用户除外的数据

expdp \' / as sysdba \'  dumpfile=test.dump logfile=test.log FULL=Y exclude=schemas:\"in\(\'USERNAM1\'\,\' USERNAM2\'\)\",TABLE:\"in\(\'TABLE_1\'\,\' TABLE_2\'\,\' TABLE_3\'\)\"

单个表导入到其它OWNER

单个表导入 （USER_1.table_name-->USER_2.table_name)
impdp  username/password DIRECTORY=ORACLE_HOME DUMPFILE=expdp_table_name.dmp REMAP_SCHEMA=USER_1:USER_2 TABLES=USER_1.table_name   logfile=impdp_USER_1.log

导入到另一个表名

（USER_1.table_name-->USER_1.table_name_tmp)
impdp \' / as sysdba \'  directory=dump_dir dumpfile=dumpfile.dmp logfile=impdp_tablename.log TABLES=USER_1.table_name  REMAP_TABLE=table_name :table_name_tmp  

整个用户导入（USER_1--> USER_2 )
impdp   \' / as sysdba \'   DIRECTORY=ORACLE_HOME DUMPFILE=table_name.dmp SCHEMAS=USER_1 REMAP_SCHEMA=USER_1:USER_2

导出XXX开头的表
expdp \"sys/XXX as sysdba\"  DIRECTORY=BACKUP_DIR dumpfile=MERCHANDISE_bakcup.dmp logfile=expdp_MERCHANDISE.log  include=TABLE:\"LIKE \'MERCHANDISE%\'\" owner='USER_1'

只导出DBLINK

expdp  \"sys/password as sysdba \" directory=BST_DIR full=y include=db_link dumpfile=temp.dmp log=temp.log
导出指定DBLINK
expdp  \"sys/ password@dbname as sysdba \" directory=BACKUP_DIR  include=DB_LINK:\"in\(\'LINK_tmp\'\)\" dumpfile=temp.dmp log=temp.log  full=y
impdp   \"sys/ password as sysdba \" directory=DATA_PUMP_DIR full=y include=db_link dumpfile=temp.dmp log=temp.log

oracle  impdp 直接从源库导入到目的库

点击(此处)折叠或打开

 #!/bin/bash
 v_date=`date "+%Y%m%d%H%M"`
 v_tables=$1
 link_user=xxx    #源库username
 link_passwd=xxx  #源库password
 link_ip=192.168.1.9 #源库IP
 link_service=orcl  #源库service_name
 sqlplus -s / as sysdba << EOF
 create directory DMPDP_DIR_tmp as '/home/oracle/';
 drop public database link link_tmp;
 create public database link link_tmp
 connect to $link_user IDENTIFIED BY "$link_passwd"
 using '(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = $link_ip)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = $link_service)))';

 EXIT
 EOF

 echo "impdp tables:${v_tables}"
 #impdp \' / as sysdba\' directory=DMPDP_DIR table_exists_action=replace network_link=link_tmp cluster=N logfile=impdp_1${v_date}.log include=TABLE:\"LIKE \'MERCHANDISE_%\'\" schemas='test'
 impdp \' / as sysdba\' directory=DMPDP_DIR_tmp table_exists_action=REPLACE network_link=link_tmp cluster=N logfile=impdp_${v_date}.log tables=$v_tables

 sqlplus -s / as sysdba << EOF
 drop public database link link_tmp;
 drop directory DMPDP_DIR_tmp;

 exit
 EOF

注意问题：
  IMPDP先导入metadata_only，再导入数据，物化视图会变成表。
