Re: migrate database

Replies:
Adar absolutely right. Instead to use "cross-platform transportable
tablespace" in case of SYSTEM tablespace you have to use a
"cross-platform transportable DATABASE" feature.
Then you can transport a minimum set of tablespace SYSTEM, UNDO, SYSAUX.
To do that you have to use RMAN, instead of the traditional
transportable tablespace procedure.

If the initial question was: Can I transport a SYSTEM tablespace
across different platforms?
Answer would be: Yes, with some limitations using "cross-platform
transportable DATABASE", and restore through RMAN min set of
tablespaces.

Limitation in that case is endian format. It is well described in the
10g doc (see below)
Cheers,

PS Next week I going to play with that feature, moving SYSTEM
tablespace from Linux to Win. Ill update the thread with the results.

Page 15-7, Cross-Platform Transportable Database: RMAN CONVERT DATABASE,

Restrictions on Cross-Platform Transportable Database
The principal restriction on cross-platform transportable database is
that the source
and destination platform must share the same endian format. For
example, while you
can transport a database from Microsoft Windows to Linux for x86 (both
little-endian),
or from HP-UX to AIX (both big-endian), you cannot transport a whole
database from
HP_UX to Linux for x86 using this feature. You can, however, create a
new database on
a destination platform manually, and transport needed tablespaces from
the source
database using cross-platform transportable tablespace as described in
