ABSTRACT:
A highly available transaction recovery service migration system in accordance with one embodiment of the present invention implements a server's Transaction Recovery Service (TRS) as a migratable service. In one embodiment of the present invention, the TRS is a server instance or software module implemented in JAVA. The TRS migrates to an available server that resides in the same cluster as the failed server. The migrated TRS obtains the TLOG of the failed server, reads the transaction log, and performs transaction recovery on behalf of the failed server. The migration may occur manually or automatically on a migratable services framework. The TRS of the failed server migrates back in a fail back operation once the failed primary server is restarted. Failback operation may occur whether recovery is completed or not. This expedites recovery and improves availability of the failed server thereby preserving the efficiency of the network and other servers.
