千家信息网最后更新 2025年01月19日expdp 和impdp使用之一(不同用户和不用表空间)

1、创建DIRECTORY

SQL> create or replace directory dir_dp as '/fol/dir_dp';Directory created.

2、授权

SQL> grant read,write on directory dir_dp to scott;Grant succeeded.

3.查看目录及权限

SQL> set lines 200 pagesize 1000SQL> SELECT privilege, directory_name, DIRECTORY_PATH FROM user_tab_privs t, all_directories d WHERE t.table_name(+) = d.directory_name ORDER BY 2, 1;PRIVILEGE       DIRECTORY_NAME                 DIRECTORY_PATH--------------- ------------------------------ ----------------------------------------------------------------------------------------------------READ            DATA_FILE_DIR                  /fol/app/oracle/product/11.2.0/db_1/demo/schema/sales_history/READ            DATA_PUMP_DIR                  /fol/app/oracle/admin/CPP/dpdump/READ            DATA_PUMP_DIR                  /fol/app/oracle/admin/CPP/dpdump/WRITE           DATA_PUMP_DIR                  /fol/app/oracle/admin/CPP/dpdump/WRITE           DATA_PUMP_DIR                  /fol/app/oracle/admin/CPP/dpdump/READ            DIR_DP                         /fol/dir_dpWRITE           DIR_DP                         /fol/dir_dpREAD            LOG_FILE_DIR                   /fol/app/oracle/product/11.2.0/db_1/demo/schema/log/WRITE           LOG_FILE_DIR                   /fol/app/oracle/product/11.2.0/db_1/demo/schema/log/READ            MEDIA_DIR                      /fol/app/oracle/product/11.2.0/db_1/demo/schema/product_media/READ            ORACLE_OCM_CONFIG_DIR          /fol/app/oracle/product/11.2.0/db_1/ccr/stateWRITE           ORACLE_OCM_CONFIG_DIR          /fol/app/oracle/product/11.2.0/db_1/ccr/stateREAD            ORACLE_OCM_CONFIG_DIR2         /fol/app/oracle/product/11.2.0/db_1/ccr/stateWRITE           ORACLE_OCM_CONFIG_DIR2         /fol/app/oracle/product/11.2.0/db_1/ccr/stateREAD            SS_OE_XMLDIR                   /fol/app/oracle/product/11.2.0/db_1/demo/schema/order_entry/WRITE           SS_OE_XMLDIR                   /fol/app/oracle/product/11.2.0/db_1/demo/schema/order_entry/READ            SUBDIR                         /fol/app/oracle/product/11.2.0/db_1/demo/schema/order_entry//2002/SepWRITE           SUBDIR                         /fol/app/oracle/product/11.2.0/db_1/demo/schema/order_entry//2002/Sep                XMLDIR                         /fol/app/oracle/product/11.2.0/db_1/rdbms/xml19 rows selected.SQL> select DEFAULT_TABLESPACE from dba_users where username='SCOTT';DEFAULT_TABLESPACE------------------------------USERS

4.执行导出

目标库:

1、创建测试表空间和用户

SQL> create tablespace LLC datafile '+DATA/phub/datafile/LLC01.dbf' size 5G;Tablespace created.SQL> create user lilc identified by lilc default tablespace LLC;User created.SQL> grant dba to lilc;Grant succeeded.SQL> conn lilc/lilc;Connected.SQL> select DEFAULT_TABLESPACE from dba_users where username='LILC';DEFAULT_TABLESPACE------------------------------LLC

2.创建DIRECTORY

SQL> create or replace directory dir_dp as '/home/oracle/dir_dp';Directory created.

3.授权

SQL> grant read,write on directory dir_dp to lilc;

4.执行导入:

更换表空间和更换用户导入:
