Iam getting the following error, when i tried without giving until cancel option.
Can't we recover the database from RMAN whose online redologs are lost?

RMAN> recover database using backup controlfile;

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
