Riyaj, Thanks for your reply. I am trying to do an incomplete recovery of the database to a full backup I took a few days ago. Its in noarchivelog mode and I don't want to go past the backup. The first restore I tried (via enterprise manager - yes I know, I _have_ to press all the buttons) was straightforward and without the check readonly option and it said it was ignoring the read only datafile: RMAN> run { 2> restore database; 3> recover database noredo; 4> } ... datafile 13 not processed because file is read-only ... RMAN> alter database open resetlogs; RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of alter db command at 04/15/2008 15:35:19 ORA-01122: database file 13 failed verification check ORA-01110: data file 13: '/data/oradata/ESDCWTST/ASSETS_21.dbf' ORA-01206: file is not part of this database - wrong database id I have tried to take the tablespace offline, but it doesn't let me because the database is not open.
