2、使用dbms_file_transfer包：
SQL> select open_mode from v$database; OPEN_MODE----------READ WRITE SQL> create or replace directory SOURCE_DIR1 as '+DATA01/dbname/onlinelog/'; Directory created. SQL> create or replace directory ORACLE_DEST as '/arch2/'; Directory created. SQL> SQL> BEGIN 2 dbms_file_transfer.copy_file( 3 source_directory_object =>'SOURCE_DIR1', 4 source_file_name => 'group_1.274.730565825', 5 destination_directory_object => 'ORACLE_DEST', 6 destination_file_name => 'group_1.274.730565825' 7 ); 8 END; 9 / PL/SQL procedure successfully completed. SQL> ! ls -l /arch2/group_1.274.730565825-rw-r----- 1 oracle oinstall 524288512 Mar 14 10:49 /arch2/group_1.274.730565825 |
