Hi, List, I am testing a disaster recovery senario. RMAN backup was done with no catalog. Below are what I did: 1. startup nomount 2. restore spfile from xxx 3. shutdown 4. startup (this time it picks up the restored spfile) 5. restore controlfile from xxx 6. alter database mount 7. restore database check readonly (I have 2 read only tablespaces) 8. recover database until logseq 5 (log seq 4 was the last archivelog backed up by rman) everything worked fine until step 8, I got an error on step 8 until follows: ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below ORA-01122: database file 9 failed verification check ORA-01110: data file 9: 'H:\xxx\xxx\xxx.dbf' ORA-01206: file is not part of this database - wrong database id file 9 is one of the READ ONLY tablespaces. Any comment on what's wrong in here? TIA, -Li
