Abstract

A method and apparatus for data recovery for a RDBMS instance in a heterogeneous database system is provided. A failure of a first RDBMS instance is detected in a plurality of RDBMS instances of a shared-disk database system. A compute cluster is configured to store, in memory, one or more tables stored by the shared-disk database system. The first RDBMS instance is configured to modify the one or more tables stored by the shared-disk database system and transfer modified data to the compute cluster to update the one or more tables at the compute cluster. After detecting the failure of the first RDBMS instance, redo records generated by the first RDBMS instance are scanned, pending modified data that was not transferred to the compute cluster before the failure is identified, and the pending modified data is transferred to the compute cluster.
