Vivek, The checkpointing library has examples in the openais source tarball and is well documented in the sa forum specifications. Essentially the active node writes its current state every time a change occurs. When a failure occurs, the standby node reads the checkpoint state. Now this new running application has a complete copy of the entire system state available for its use.
I am not exactly certain how you would integrate this with rg manager but it could be done. The CKPT service is really designed to work with AMF, but AMF in openais and especially rhel5+derivatives is unstable and I can't recommend using the AMF for production environments.
