Hi!

I use oracle8i for linux

I delete rollback segment's file by mistake.
(with rm command)

and I couldn't open DB.

That's DB message.

ORACLE instance started.
Total System Global Area 4754704 bytes
Fixed Size 48400 bytes
Variable Size 4222976 bytes
Database Buffers 409600 bytes
Redo Buffers 73728 bytes
Database mounted.
ORA-01545: rollback segment 'R01' specified not available
ORA-01109: database not open

And I edited init.ora

# rollback_segments = (r01,r02,r03,r04)

and tried to startup DB.
but error was occured.

ORA-00376: file 2 cannot be read at this time

How can I open DB?
