We have a test server; it has completely crashed, so I have to restore everything from the backup. This restore & recovery doesn’t have a recovery catalog. I started with spfile, controlfile and DB recovery.
Note: when you are allocating the channel & no of channels, you have specified
Accordingly to system perform. It can be either from disk & tape. In the below example i have used TAPE. so i have used the below option.STEP#1
If you have backup of spfile or old pfile, start DB with it.
You can see below link which has the step by step restoration of spfile from TAPE
http://oracledbabhuvan.blogspot.com/2011/10/restoring-spfile-from-autobackup-mode.html
STEP#2
A) If you have recover catalog available then use the below option
bhuora01[BHU_1]>rman target / catalog rman/rman@catalog

connected to target database: BHU (not mounted)
RMAN> restore controlfile from autobackup;
Note: Allocate channel as your environment and no need to set the DBID, recovery catalog will have all the details.
B) If you don’t have recover catalog available then use the below option
1) set DB ID (you can find from the alert log of the database)
2) Issue “restore controlfile from autobackup;”

STEP#3
If you are using ASM disk and spfile, then the system will change the control file naming conversation automatically.
If you are using ASM and using pfile then you have change the controlfile name after restoring the controlfile.
Note: If you are creating spfile before the DB is mount, DB SPFILE will be created in the UNKNOWN Directory in the specified Disk group.
