Database full recovery and restore right upto the last online redolog transaction:

Verify which backup you have:

Rman target /

List backup;

Inr 0




Incr 1

               
    












Spool remove_database_files.sh

/



Spool off

Exit




Vi remove_database_files.sh

:wq

Sh ./remove_database_files.sh

At this point the database data files got completely deleted from os level

How to restore and recover full database at this point:






List backup:

RMAN>restore database;

Here it will restore from incr 0




 

As you see it will restore from _c2kxcltc_bkp

Which has incr 0 backup



2.

RMAN>recover database;

Note: here recover database will recover from incr 1



See it includes incr 1




Finally

RMAN>Alter database open;




Exit

Sqlplus / as sysdba







Exit

To check trace log

Cd /home/oracle/diag/rdbms/orcl/trace

Vi ale*.log

You can see

Recovery of online redo log
