Oracle備份恢復impdp/expdp

 

1、導出表空間

select * from dba_directory where directories_name='';

SQL>conn sys as sysdbaSQL;

SQL>grant read,write on directory dumpdir to y;

SQL>grant dba to y;

SQL> conn y/123

SQL>alter tablespace test1 read only;

SQL>!expdp directory=dumpdir dumpfile=tbs.dmp transport_tablespaces=test1

2.導入表空間

! impdp directory=dumpdir dumpfile=tbs.dmp transport_datafiles='/home/oracle/oracle/oradata/db2/test1.dbf'

 

其它導入導出

1.導出

expdp directory=dumpdir dumpfile=full.dmp full=yexpdp directory=dumpdir dumpfile=tbs.dmp tablespaces=test1,test2
expdp directory=dumpdir dumpfile=table.dmp tables=test1,test2expdp directory=dumpdir dumpfile=schma.dmp schemas=test1,test2

2.導入

impdp directory=dumpdir dumpfile=full.dmp full=yimpdp directory=dumpdir dumpfile=tbs.dmp transport_datafiles='/home/oracle/oralce/oradata/db2/test1.dbf', '/home/oracle/oralce/oradata/db2/test2.dbf'impdp directory=dumpdir dumpfile=table.dmp tables=test1,test2impdp directory=dumpdir dumpfile=schma.dump schemas=test1,test2

3、網絡導入表空間

create public database link hq connect to hq identified by hq using ’

這裏，第一個hq是dblink名，第二個hq是源數據庫用戶名，第三個hq是源數據庫hq用戶密碼，209是網絡連接服務名，從tnsnames.ora文件中獲取的。

 create database link TEST.US.ORACLE.COM
  connect to user identified by pwd
  using '(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = IP)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)
    )
  )';
