CORBA26 — Component assembly templates

  • Key: CORBA26-59
  • Legacy Issue Number: 4078
  • Status: closed  
  • Source: Iconixx ( Thomas Hawker)
  • Summary:

    In a complex distributed environment, the implementation of highly
    available and highly reliable services requires redundant placement of
    software components in all their manifestations. Assemblies provide a
    nice, convenient way of specifying the deployment and activation of
    components and the connections that relate them for a particular
    purpose. Now, for various reasons and Fault Tolerant CORBA
    notwithstanding, in corporate reality this sequence and specification
    will occur in multiple places in basically identical fashion. About the
    only thing that changes are the host names and their network addresses;
    everything else from the hardware configuration to the size of the disk
    drives and file systems is (and inherently must be) exactly the same
    among all deployments. This, for example, is one technique to support
    geographic site failover.

    My question is, has anyone thought of a two or more stage XML process,
    one in which the package or assembly composition and deployment XML is
    specified as a template or configurable, parameterized entity, and
    another where the parameters have been substituted for "finalization"?
    This can occur at two distinct points in the life-cycle: one set of
    substitutions occurring when an artifact is deployed (installed?) on the
    various computer systems involved, and another when the home [and
    possibly individual instances] of the artifacts are activated
    (instantiated?) to run on those computer systems. My work in the
    telecom and defense industries has show that deployment of anything is
    rarely a singleton event; there are always redundancies, replications,
    and backups to take into account. Templates seem to provide a nice
    solution to all of the manual editing required.
