Answer 1

hmmm ok, so it seems that you dont use RMAN to backup your database...
It seems there that your have a controlfile problem after a disk crash. I hope your database is on ARCHIVELOG mode.
Does your database crashed during activity or was idle ?
1. Mount the database
2. set autorecovery on ;
recover database using backup controlfile ;
media recovery complete <= this means that all is ok now
3. alter database open resetlogs ;
if #2 doesnt work cause of redo log problem such as corrupted redo log, or some transactions "blocked" in theses redo log cause of a big crash during the database activity, Oracle will tell you that a redo log is corrupted and will give you the hour of the redo log log entry that Oracle need to recover.
So you will have to make an incomplete recovery (that means you will lose some datas, no much but some) until time.
For example, your redo entry has been corrupted at 12:00:50
1. recover database until time '2003-08-25:12:00:00' ;
2. alter database open resetlogs ;
3. Make a full backup of your database !
