I have checked the alert file it shows

ORA-00202 : controlfile : ' path'
ORA-27041: unable to open file
ORA-205 signalled during : alter database mount ..message

I have checked the controlfiles in oracle_home/oradata/name/

> controlfiles not available(controlfiles missing)

we have updated controlfile trace files(both textform and binary form)

ORA-27041: unable to open file

You have binary control file backup or text file ???

if binary file then edit control_file parameter in init.ora file and point binary ctl file backup

otherwise if you have text file backup then create new control file from text file backup.

Taj

Restoring the Control File

This example restores the control file to its default location, 
replicates it to all CONTROL_FILES locations, 
and mounts the database:

startup nomount;
run { 
     restore controlfile; 
     alter database mount; 
}

Mohammad Taj already pointed your solution whether you have binary or text of backup. If you don't want to follow anyone of them, then use,

SQL>rman target /
rman>startup nomount;

Restore controlfile to '/oradata/test/' from '/mnt/ora_backup/ctl.bkp'

Restore controlfile to '/oradata1/test/' from '/mnt/ora_backup/ctl.bkp'
