since i did not have mirror copy or backup of current control file to replace the correpted one.
Is there any way to create new control file and transfered to ASM diskgroup and open database. or i need to drop the existing database.
if i need to drop the db, without open the db how to drop database.
kindly help on this.
Thanks in advance.
