1. A system of loading and registering a software program in a cluster network database, coupled to a first server and a second server in a server network, comprising:

  • a primary load module which loads the program in the first server;

    a preregistration module which determines if the program was previously registered;

    an object module which creates an object for the program and stores the object in the database, if it is determined that the program was not previously registered;

    a nonfailure module which determines if a system operator previously unloaded the program;

    a phoenix detect module which determines if the first server is coming back from a failback process, if it is determined that the system operator did not previously unload the program; and

    a synchronization module which synchronizes all replicated databases within the network, if it is determined that the first server is not coming back from failback process.
