This is the way I started to go 2 hours ago. I assumed, that the tablespaces are the .dbf files , for exmaple : system01.dbf

I created 4 raw partitions with apriopriate sizes c2t0d0s[3456]

I created file named 'mapping_ascii', which included lines :

/aw/oracle_new/oradata/dpikpok/system01.dbf    /dev/rdsk/c2t0d03
/aw/oracle_new/oradata/dpikpok/users01.dbf    /dev/rdsk/c2t0d04
/aw/oracle_new/oradata/dpikpok/rbs01.dbf    /dev/rdsk/c2t0d05
/aw/oracle_new/oradata/dpikpok/temp01.dbf    /dev/rdsk/c2t0d06

I export(ed) the environment variable DBCA_RAW_CONFIG which pointed on 'mapping_ascii" file

then I started dbassist and created database with name 'dpikpok' and it created these table spaces on on ufs filesystem instead of creating it on raw devices

what am I doing wrong ?
