NO.

You can replace the whole database from the ghost image.

The database will refuse to open.
In each & every datafile the current SCN resides.
All the SCNs must match each other or the database won't open.
If you don't believe me, try it your self;
but 1st take a complete cold backup of what you have so you can at least get back from where you started.

Then you will have an empty datafile.
Why don't you have complete & recent backups?

I am scared that if i restore the full D drive from ghost image then further probles can arise. Because my operating system is on c drive and ghost image is on d drive.

When was the ghost image made?
In other words how many hours, days, weeks of data will be lost by restoring from ghost image?

How could it be worse than having a database that won't open?

Why don't you have complete & recent backups?

I regularly take the backup of database server that is on a different machine. While proble is on Application server that is on another machine.

I take the backup using rman. By cold back you mean simply copy the contents of whole D drive?

Ghost was created 7-8 days ago and this problem arise 2 days before.

And one more question: If I restor the GCATS1_OID.DBF datafile from ghost image and then use "startup ount" and "recover database" commanad?

I have NO idea how many different/specific system by count exist.

>I take the backup using rman.
Good for you.

>By cold back you mean simply copy the contents of whole D drive?
I thought the ghost image is on D drive & corrupted database is on C drive.
Do I understand correctly?
If so, take backup of C before overwriting C drive with contents of D drive.

>Ghost was created 7-8 days ago and
>this problem arise 2 days before.
2 days before WHEN?
2 days before today?
2 days before ghost image?

I have restored the GCATS1_OID.DBF datafile. Now it is asking for media recovery:

SQL> alter database open
2 ;
alter database open
*
ERROR at line 1:
ORA-01113: file 24 needs media recovery
ORA-01110: data file 24: 'D:\ORACLEAS\ORADATA\ORCL\GCATS1_OID.DBF'

Please guide me more for further steps.

'D:\ORACLEAS\ORADATA\ORCL\GCATS1_OID.DBF'

Let us review.
No archive mode & no backups.
Obviously the data had NO value.
so create a new,empty database & start from empty/scratch database.

For tablespace OLTS_CT_STORE, is GCATS1_OID.DBF file only datafile for this tablespace?

what data?
If you have it (the data) then you have not lost it.
If you don't have it, I hope you have backups.
Please decide what you have or not.
