Oracle使用impdp進行用戶複製

impdp數據庫遷移（單用戶複製）

關應用

停止所有對數據庫的RUD操作

在新數據庫中刪除及創建用戶及賦權

sqlplus / as sysdba
create user bjzjxt identified by Admin123
grant connect, resource, dba to bjzjxt;
grant create public database link to bjzjxt;

創建虛擬路徑

create directory dppath as '/u01/dppath';

給新用戶賦讀取及修改路徑的權限

grant read, write on directory dppath to bjzjxt;

創建dblink

create public database link bjzjxt_old connect to bjzjxt identified by Admin123 using '(DESCRIPTION =(ADDRESS_LIST =(ADDRESS =(PROTOCOL = TCP)(HOST = 192.168.100.9)(PORT = 1521)))(CONNECT_DATA =(SERVICE_NAME = ORCL11G)))'; 

複製數據

impdp bjzjxt/Admin123 directory=dppath  network_link=bjzjxt9 remap_schema=bjzjxt:bjzjxt;
