V 8.05 - Corrupted tablespace file for schema - cannot open database

Question

Group,
Sun 450 Enterprise running Solaris 6. No hardware failures or problems.
I have a database that will not open, and here's the info I think you'll need:
Several schemas, each in it's own tablespace. Only one schema, production is needed, and it's fine. The test schema "tst" got it's tablespace files replaced by one of our admins. I DO NOT need any of the data in any schema but production, and it's files are OK.
When I attempt to open the database to drop the tablespace and contents, I get:
Logged on as oracle owner
svrmgrlSVRMGR> connect internal
SVRMGR> startup
SGA message
Buffermessages
Database mounted.
ORA-01122: database file 5 failed verification check
ORA-01110: data file 5: '/oracle01/max/tst01.dbf'
ORA-01251: Unknown File Header Version read for file number
SVRMGR>drop tablespace tst including contents;
ORA-011109: database not open
I have tried "startup force open" - same error, just about every combination of svrmgrl options I can think of.
All I want is to get Oracle to ignore those "tst" schema (tablespace) files.
Thanks,
Vince

You could try :
startup
alter database datafile 'your_datafile_name' offline drop;
alter database open;
drop tablespace your_tablespace_name;Nicolas.Wouldn't that need to be a 'startup mount'?I assume the startup will "partially" failed, and then the db will be in mount status...
