Error description

  • Following KC pages describe the Global cache configuration in
    multi-instance int node configuration.

    port/knowledgecenter/SSTTDS_11.0.0/com.ibm.etools.mft.doc/bn2379

    There is a concern
    over following statement:
    
    "A multi-instance integration node
    cannot be used to host an integration server with a catalog
    server."
    
    As there are no qualifications on the statement as
    to when it applies. Additionally, this statement can be taken
    out of context as a blanket statement for support/functionality
    of global cache with multi-instance Int.Nodes.
    
    In the
    scenario where users do not intend to make cache highly
    available in a multi-instance Int node setup, then they can
    host catalog server on the multi-instance integration node with
    the awareness that when the multi-instance integration node
    fails over, the cache would be lost.
    
    The KC pages needs to be
    updated to reflect the scope of the statement:
    
    A
    multi-instance integration node cannot be used to host an
    integration server with a catalog server in this example.?
    
    In
    this scenario, a multi-instance integration node cannot be used
    to host an integration server with a catalog server.?

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of App Connect Enterprise V11.0 using Global Cache
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    In context of using Global Cache in a multi-instance integration
    node topology, the knowledge center states that
    "A multi-instance integration node cannot be used to host an
    integration server with a catalog  server."
    
    However, if an user does not intend to make the cache highly
    available and only needs to use the cache within
    the running integration node,  the catalog server can still be
    hosted on the multi-instance integration node. It is to be noted
    that when active integration node fails over to standby node,
    the cache would be lost and it will need to be reloaded on the
    failed over integration node.
    

Problem conclusion

  • The product knowledge center topics   bn23780_ and   bn23793_
    have been updated to clarify the  context in which the catalog
    servers in multi-instance integration node topology are not
    recommended.
