--------------------------------------------------------------
В техническом плане статья просто следует документации по RMAN в версии 10g.
Однако, сама процедура гораздо легче для понимания когда читаешь статью,
чем когда работаешь с документацией.Автор опускает процедуру перемещения
Flash Recovery Area в ASM,либо просто педпочитает оставить область на файловой
системе.Техническиий английский для понимания не сложен.
В отношении ASM в версии Oracle10g, мне известна только англоязычная статья
см. http://www.opennet.ru/opennews/art.shtml?num=4589 пункт 2.

Converting Oracle10g non-ASM database to ASM
This article is technical exercise following general guidelines
of Oracle 10g Rman's Reference Manual.However,two times I was unable to
reproduce instructions from Reference and had to manage on my own .
The new Recovery Manager features in version 10g providing ability to migrate
database from file system into AMS looks very impressive.
Make sure ASM instance is up. Suppose also ASM volume group +DATA1
has been already created. Create database "convdata" with "dbca" in /u02/oradata.
Copy corresponding init.ora file to $ORACLE_HOME/dbs.
$cp /u01/app/oracle/admin/convdata/pfile/init.ora.929200412032 \
> $ORACLE_HOME/dbs/initconvdata.ora
$cd $ORACLE_HOME/dbs
Add following entries to initconvdata.ora :-
CONTROL_FILES='+DATA1/controlf01'
DB_CREATE_FILE_DEST='+DATA1'
DB_CREATE_ONLINE_LOG_DEST_1='+DATA1'
$ mv spfileconvdata.ora spfileconvdata.ora.orig
$ export ORACLE_SID=convdata
$ $ORACLE_HOME/bin/rman

Можно избежать если перед ASM конвенртацией активировать "Autoarchiving". В этом случае:-
