摘要：Method, system, apparatus and/or computer program for achieving transparentintegration of high-availability services for distributed application programs. Loss-less

migration of sub-programs from their respective primary nodes to backup nodes isperformed transparently to a client which is connected to the primary node. Migration isperformed by high-availability services which are configured for injecting registrationcodes, registering distributed applications, detecting execution failures, executing frombackup nodes in response to failure, and other services. High-availability applicationservices can be utilized by distributed applications having any desired number of sub-programs without the need of modifying or recompiling the application program andwithout the need of a custom loader. In one example embodiment, a transport driver isresponsible for receiving messages, halting and flushing of messages, and for issuingmessages directing sub-programs to continue after checkpointing.
