Hi,
My primary db (10g R2 Soalris)  has a tablespace created by transported
it from other database  (using oracle transportable tablespace ). it
has two datafiles (aa01 and bb02.dbf).  The tablespace is read
writeable.

I then tred to create a logical standby db for the primary db using
RMAN.  During creation, Oracle report such error:

   Part one:
   ORA-19502: write error on file "/oracle/oradata/**/aa01.dbf"
   ORA-27063: number of bytes read/written is incorrect
   SVR4 Error: 28: No space left on device

This is weird since there are plenty space left on disk

   Part two:
   creating datafile fno=7 name=/oracle/oradata/**/bb02.dbf
   RMAN-06136: ORACLE error from auxiliary database: ORA-19723: Cannot
recreate plugged in read-only datafile 7

The message is misleading. bb02.dbf belongs to a read write tablespace.

did anyone know anything about that? is it a bug either in
transportable db or logical standby?

thanks in advance.
