  7. Reconfiguring the Server
    The server configuration limits the number of:



        Clients that can connect to the server at the same time

        Disk services that can be in use simultaneously

    Because users' demands change over time, you may need
    to adjust the configuration periodically. For example, you
    may need to add more clients so more users can connect
    to the server. Because additional clients and disk services
    use system resources, you do not want to configure the
    server for more clients or disk services than are actually
    needed. Therefore, changing the configuration can also
    mean decreasing the number of clients or disk services.
  Changing server
  configuration can affect
  VMS resources.

    Changing the server configuration and adding layered
    products affects resources available for the VMS operating
    system. The configuration procedure ensures that enough
    resources are allocated to support the new configuration.
    When you add layered products, you also need to follow
    the configuration procedure to ensure that adequate system
    resources are available.

    Changing the server configuration can also affect
    performance. After you reconfigure the server, you may
    need to tune for performance, as explained in
Chapter 8.

    This chapter describes how to reconfigure the:



        File server to change the number of clients

        (Clients are referred to as workstations in the software.)



        Disk server to change the number of disk services

        Local Area System Transport software to change group
        codes and disk server timeout
