694. As part of archiving the historical data, you want to trans fer data from one database to another

database, which is on another server. All tablespaces in the source database are read/write and online.

The source and target databases use the same  compatibility level and character sets.  

View the Exhibit and examine the features in the source and target database.

Which of the following steps are required to transport a tablespace from the database to the target database:

1.Make the tablespace read-only at the source database.

2.Export metadata from the source database.

3.Convert data filed by using Recovery Manager (RMAN).

4.Transfer the dump file and data filed to the target machine.

5.Import metadata at the target database.

6.Make the tablespace read/write at the target database.

A.2, 4, and 5

B.All the steps

C.2, 3, 4 and 5

If both platforms have the same endianness, no conversion is necessary. Otherwise you must do a conversion of the tablespace set either at the source or destination database.

If both platforms have the same endianness, no conversion is necessary因为都是32位的操作系统，故不需要转换。3不需要。故C是错误的。B也是错的。

If no endianness conversion of the tablespace set is needed, or if you already converted the tablespace set:

1. Transport the dump file to the directory pointed to by the DATA_PUMP_DIR directory object, or to any other directory of your choosing.

   Run the following query to determine the location of DATA_PUMP_DIR:

   SELECT * FROM DBA_DIRECTORIES WHERE DIRECTORY_NAME = 'DATA_PUMP_DIR';

    

   OWNER      DIRECTORY_NAME   DIRECTORY_PATH

   ---------- ---------------- -----------------------------------

   SYS        DATA_PUMP_DIR    C:apporauseradminorawindpdump

2. Transport the data files to the location of the existing data files of the destination database.

   On the UNIX and Linux platforms, this location is typically /u01/app/oracle/oradata/SID/ or +DISKGROUP/SID/datafile/.
