ASM 檔案與本地檔案的轉換
技術點：
- 如何實驗ASM檔案和本檔案的相互轉換的方法之一：dbms_file_transfer.
- bbed 運算元據檔案
- ASM 使用template來生成檔案的路徑和名稱
建立表：
SQL> create table a (id number, name char(2000)) tablespace david1;
insert into a values(1,'abc');
insert into a values(2,'def');
insert into a values(3,'ade');
insert into a values(4,'asdf');
commit;
analyze table a compute statistics;
SQL> select blocks from user_tables where table_name='A';
BLOCKS
----------
13
SQL> select dbms_rowid.rowid_relative_fno(rowid) r_fno,dbms_rowid.rowid_block_number(rowid) b_no,id from a order by 1,2;
R_FNO B_NO ID
---------- ---------- ----------

9 24 1

9 24 3
9 25 4
16 rows selected.
SQL> select name from v$datafile where file#=9;
NAME
--------------------------------------------------------------------------------
+DG1/devdb1/david1.dbf
轉換：
SQL> create directory sd as '+DG1/devdb1';
Directory created.
SQL> create directory dd as '/u01/backup';
Directory created.
SQL> alter database datafile 9 offline;
Database altered.
SQL> begin
dbms_file_transfer.copy_file(source_directory_object => 'sd',
source_file_name => 'david1.dbf',
destination_directory_object => 'dd',
destination_file_name => 'david1.dbf');
end; 2 3 4 5 6
