Sorry, I forgot to mention that the database was open with resetlog. Here is my plan to fix the issue: * shutdown immediate; * startup mount; * alter tablespace TS_INDEX_00 offline; * alter tablespace TS_INDEX_00 rename datafile '/oracle/OraHome2/dbs/MISSING00012' to '/SRV_ACEQ/server/database/data/ts_index_00_01.dbf'; * alter tablespace TS_INDEX_00 online; * alter database datafile 12 offline drop; * alter database open; * alter database create datafile 12 as '/SRV_ACEQ/server/database/data/ts_index_00_01.dbf'; * alter database datafile 12 online; * alter tablespace TS_INDEX_00 drop datafile 12; Any thought? ________________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Xu, Roger Sent: Wednesday, February 04, 2009 3:25 PM To: oracle-l@xxxxxxxxxxxxx Subject: Miss db files Hi List, In order to change the SID, we recreated the controlfile but I left 2 dbfiles out - oops! Now, Oracle KNOWS about the datafile as its in the dictionary so puts a "MISSING" entry in its place. I know there is no data in these dbfiles. What is the easiest way for me to drop them? We are on 10g which allows dropping a single dbfile but the status of the dbfile needs to be online? Thanks in advance, Roger Xu P.S.
