Limitations on Transportable Tablespace Use

The source and target database must use the same character set and national character set.

You cannot transport a tablespace to a target database in which a tablespace with the same name already exists. However, you can rename either the tablespace to be transported or the destination tablespace before the transport operation.

Objects with underlying objects (such as materialized views) or contained objects (such as partitioned tables) are not transportable unless all of the underlying or contained objects are in the tablespace set.

Encrypted tablespaces have the following the limitations:
Before transporting an encrypted tablespace, you must copy the Oracle wallet manually to the destination database, unless the master encryption key is stored in a Hardware Security Module
(HSM) device instead of an Oracle wallet. When copying the wallet, the wallet password remains the same in the destination database. However, it is recommended that you change the password
on the destination database so that each database has its own wallet password.  See Oracle Database Advanced Security Administrator’s Guide for information about HSM devices, about
determining the location of the Oracle wallet, and about changing the wallet password with Oracle Wallet Manager.

You cannot transport an encrypted tablespace to a database that already has an Oracle wallet for transparent data encryption. In this case, you must use Oracle Data Pump to export the tablespace’s
schema objects and then import them to the destination database. You can optionally take advantage of Oracle Data Pump features that enable you to maintain encryption for the data while it is being
exported and imported.
See Oracle Database Utilities for more information.

You cannot transport an encrypted tablespace to a platform with different endianness.

Tablespaces that do not use block encryption but that contain tables with encrypted columns cannot be transported. You must use Oracle Data Pump to export and import the tablespace’s schema objects. You can take advantage of Oracle Data Pump features that enable you to maintain encryption for the data while it is being exported and imported. See Oracle Database Utilities for more information.

Beginning with Oracle Database 10g Release 2, you can transport tablespaces that contain XMLTypes. Beginning with Oracle Database 11g Release 1, you must use only Data Pump to export and import the tablespace metadata for tablespaces that contain XMLTypes.

The following table shows the minimum compatibility requirements of the source and target tablespace in various scenarios. The source and target database need not have the same compatibility setting.

You can use RMAN to transport tablespaces across platforms with different endian formats. You can also use RMAN to transport an entire database to a different platform so long as the two platforms have the same endian format.

If the source platform and the target platform are of different endianness, then an additional step must be done on either the source or target platform to convert the tablespace being transported to the target format. If they are of the same endianness, then no conversion is necessary and tablespaces can be transported as if they were on the same platform.

Read only and offline files get the compatibility advanced after they are made read/write or are brought online. This implies that tablespaces that are read only prior to Oracle Database 10g must be made read/write at least once before they can use the cross platform transportable feature.
