[oracle实验]跨平台传输表空间 win -> linux

从11g开始，oracle支持跨平台传输表空间。
查看支持平台列表，如果源库和目标库的endian format不一致，需要convert

SQL> col platform_name for a32;
SQL> select * from v$transportable_platform;
PLATFORM_ID PLATFORM_NAME                    ENDIAN_FORMAT
----------- -------------------------------- ----------------------------
1 Solaris[tm] OE (32-bit)          Big
2 Solaris[tm] OE (64-bit)          Big
7 Microsoft Windows IA (32-bit)    Little
10 Linux IA (32-bit)                Little
6 AIX-Based Systems (64-bit)       Big
3 HP-UX (64-bit)                   Big
5 HP Tru64 UNIX                    Little
4 HP-UX IA (64-bit)                Big
11 Linux IA (64-bit)                Little
15 HP Open VMS                      Little
8 Microsoft Windows IA (64-bit)    Little

PLATFORM_ID PLATFORM_NAME                    ENDIAN_FORMAT
----------- -------------------------------- ----------------------------
9 IBM zSeries Based Linux          Big
13 Linux x86 64-bit                 Little
16 Apple Mac OS                     Big
12 Microsoft Windows x86 64-bit     Little
17 Solaris Operating System (x86)   Little
18 IBM Power Based Linux            Big
19 HP IA Open VMS                   Little
20 Solaris Operating System (x86-64 Little
)
21 Apple Mac OS (x86-64)            Little
20 rows selected.

使用传输表空间的限制：

1.源库和目标库必须是同样的字符集和国家字符集

SQL> col parameter for a32;
SQL> col value for a30;
SQL> select * from nls_database_parameters;
PARAMETER                        VALUE
-------------------------------- ------------------------------
NLS_LANGUAGE                     AMERICAN
NLS_TERRITORY                    AMERICA
NLS_CHARACTERSET                 AL32UTF8
NLS_NCHAR_CHARACTERSET           AL16UTF16
NLS_RDBMS_VERSION                11.2.0.3.0
......                                        ......

2.所有要传输的表空间对象必须是self-contained.意为：A表空间里的对象有引用B表空间的对象，那么表空间A和B都必须包含在transpotable set里。
不过不用担心，有DBMS_TTS包帮我们检查

下面开始实验吧：
source : windows oracle 11203 64bit
target : OEL 6.3 oracle 11203 64bit
platform,endian检查：
source:

SQL> SELECT d.PLATFORM_NAME, ENDIAN_FORMAT FROM V$TRANSPORTABLE_PLATFORM tp, V$DATABASE d WHERE tp.PLATFORM_NAME = d.PLATFORM_NAME;
PLATFORM_NAME                    ENDIAN_FORMAT
-------------------------------- ---------------------------
Microsoft Windows x86 64-bit     Little

target:

SQL> col platform_name for a30;
SQL> SELECT d.PLATFORM_NAME, ENDIAN_FORMAT FROM V$TRANSPORTABLE_PLATFORM tp, V$DATABASE d WHERE tp.PLATFORM_NAME = d.PLATFORM_NAME;
PLATFORM_NAME                  ENDIAN_FORMAT
------------------------------ --------------
Linux x86 64-bit               Little

检查表空间是否是self-cotained:

SQL> EXEC DBMS_TTS.TRANSPORT_SET_CHECK('ERM',TRUE);
PL/SQL procedure successfully completed.

在TRANSPORT_SET_VIOLATIONS视图查看执行结果，如果有依赖对象不在提供的tablespace里，会给出详细提示

SQL> SELECT * FROM TRANSPORT_SET_VIOLATIONS;
no rows selected

生成传输表空间集：

SQL> ALTER TABLESPACE ERM READ ONLY;
Tablespace altered.
SQL> create directory erm_dump_dir as 'E:\app\susu\dumpdir\';
Directory created.
SQL> grant read,write on directory erm_dump_dir to szpdc;
Grant succeeded.
SQL> host

C:\Windows\system32>expdp system/password dumpfile=erm_tts.dmp directory=erm_dum
p_dir transport_tablespaces=ERM

使用RMAN convert转换文件格式：

C:\Windows\system32>rman target /

将RMAN CONVERT生成的transport tablespace set和 expdp导出的文件 copy到目标数据库
我这里拷贝到了

[oracle@db1 dumpdir]$ pwd
/s01/app/oracle/dumpdir
[oracle@db1 dumpdir]$ ls
ERM6  ERM_TTS.DMP  import.log

接下来，在目标数据库操作：

RMAN> convert datafile '/s01/app/oracle/dumpdir/ERM6' db_file_name_convert '/s01/app/oracle/dumpdir/ERM6','/s01/app/oracle/oradata/DB11G/erm01w.dbf';

大功告成，查询
