Oracle Local Registry - OLR

OLR is the new feature in Oracle 11gR2 grid infrastructure.  The information stored in the OLR is used by the oracle high availability service daemon (OHASD) .  It includes data about the clusterware configuration, version information, and GpnP wallets.  Comparing to the OCR, OLR has fewer keys and majority of OLR keys are deal with OHASD process whereas OCR deals with CRSD process.
