ORA-00214: controlfile inconsistent error after hiberning virtual machine

Today I discovered this error while trying to start a database on my virtual machine. I think it happened because yesterday I "hibernated" several times my machine while this virtual machine and database were still running and forgot to close them.
Anyway.. this is what I've done to bring my database back to a normal and available status.

Ok.. the error is quite clear. I need to remove a controlfile. Let me see my configuration and where are located my controlfiles.

I tried to use only one controlfile and see if my database likes it.

System altered.

Ok.. the first controlfile is the good one, so I have to copy it to my second controlfile location

idle> host
[oracle@plutone ~]$ cp /DATA/DB11G/control01.ctl /u01/app/oracle/flash_recovery_area/DB11G/control02.ctl
[oracle@plutone ~]$ exit
exit

Start the instance again in nomount mode and add the second controlfile.

That's all.
