   The management server is the process that reads the cluster
        configuration file and distributes this information to all nodes
        in the cluster that request it. It also maintains a log of
        cluster activities. Management clients can connect to the
        management server and check the cluster's status.

      Using one of the options just listed is effective only if
            the management server has no stored configuration at the
            time it is started. If the management server finds any
            configuration cache files, then the
      <code class="option">
       --config-cache
      </code>
      option or the
      <code class="option">
       --skip-config-cache
      </code>
      option is ignored.
            Therefore, to disable configuration caching, the option
            should be used the
      <span class="emphasis">
       <em>
        first
       </em>
      </span>
      time that the
            management server is started. Otherwise—that is, if
            you wish to disable configuration caching for a management
            server that has
      <span class="emphasis">
       <em>
        already
       </em>
      </span>
      created a
            configuration cache—you must stop the management
            server, delete any existing configuration cache files
            manually, then restart the management server with
      <code class="option">
       --skip-config-cache
      </code>
      (or with
      <code class="option">
       --config-cache
      </code>
      set equal to 0,
      <code class="literal">
       OFF
      </code>
      , or
      <code class="literal">
       FALSE
      </code>
      ).
     </p>
     <p>
      Configuration cache files are normally created in a
            directory named
      <code class="filename">
       mysql-cluster
      </code>
      under the
            installation directory (unless this location has been
            overridden using the
      <a class="link" href="mysql-cluster-programs-ndb-mgmd.html#option_ndb_mgmd_configdir">
       <code class="option">
        --configdir
       </code>
      </a>
      option). Each
            time the management server updates its configuration data,
            it writes a new cache file. The files are named sequentially
            in order of creation using the following format:
     </p>

      <em class="replaceable">

      </em>
      is the management
            server's node ID;
      <em class="replaceable">
       <code>
        seq-number
       </code>
      </em>
      is a sequence number, beginning with 1. For example, if the
            management server's node ID is 5, then the first three
            configuration cache files would, when they are created, be
            named
      <code class="filename">
       ndb_5_config.bin.1
      </code>
      ,
      <code class="filename">
       ndb_5_config.bin.2

      .

      If your intent is to purge or reload the configuration cache
            without actually disabling caching, you should start

      Configuration data is cached internally, rather than being
            read from the cluster global configuration file each time
            the management server is started (see
      <a class="xref" href="mysql-cluster-config-file.html" title="25.4.3 NDB Cluster Configuration Files">
       Section 25.4.3, “NDB Cluster Configuration Files”
      </a>
      ). Using the
      <code class="option">
       --initial
      </code>
      option overrides this behavior,
            by forcing the management server to delete any existing
            cache files, and then to re-read the configuration data from
            the cluster configuration file and to build a new cache.
     </p>
     <p>
      This differs in two ways from the
      <a class="link" href="mysql-cluster-programs-ndb-mgmd.html#option_ndb_mgmd_reload">
       <code class="option">
        --reload
       </code>
      </a>
      option. First,
      <code class="option">
       --reload
      </code>
      forces the server to check the
            configuration file against the cache and reload its data
            only if the contents of the file are different from the
            cache. Second,
      <code class="option">
       --reload
      </code>
      does not delete any
            existing cache files.
     </p>
     <p>

        <strong>
         ndb_mgmd

      </a>
      is invoked with
      <code class="option">
       --initial
      </code>
      but cannot find a global
            configuration file, the management server cannot start.
     </p>
     <p>
      When a management server starts, it checks for another
            management server in the same NDB Cluster and tries to use
            the other management server's configuration data. This
            behavior has implications when performing a rolling restart
            of an NDB Cluster with multiple management nodes. See
      <a class="xref" href="mysql-cluster-rolling-restart.html" title="25.6.5 Performing a Rolling Restart of an NDB Cluster">
       Section 25.6.5, “Performing a Rolling Restart of an NDB Cluster”

            information.

       </code>
      </a>
      option, the
            cache is cleared only if the configuration file is actually
            found.

     <p>
      Specify a list of directories to search for a CA file. On
            Unix platforms, the directory names are separated by colons
            (
      <code class="literal">
       :
      </code>
      ); on Windows systems, the semicolon
            character (
      <code class="literal">
       ;
      </code>
      ) is used as the separator. A
            directory reference may be relative or absolute; it may
            contain one or more environment variables, each denoted by a
            prefixed dollar sign (
      <code class="literal">
       $
      </code>
      ), and expanded
            prior to use.
     </p>
     <p>
      Searching begins with the leftmost named directory and
            proceeds from left to right until a file is found. An empty
            string denotes an empty search path, which causes all
            searches to fail. A string consisting of a single dot
            (
      <code class="literal">
       .
      </code>
      ) indicates that the search path
            limited to the current working directory.
     </p>
     <p>
      If no search path is supplied, the compiled-in default value
            is used. This value depends on the platform used: On
            Windows, this is
      <code class="literal">
       \ndb-tls
      </code>
      ; on other
            platforms (including Linux), it is
      <code class="literal">
       $HOME/ndb-tls
      </code>

      When starting an NDB Cluster is configured with two
            management nodes, each management server normally checks to
            see whether the other
      <a class="link" href="mysql-cluster-programs-ndb-mgmd.html" title="25.5.4 ndb_mgmd — The NDB Cluster Management Server Daemon">

         ndb_mgmd
        </strong>
       </span>
      </a>
      is also
            operational and whether the other management server's
            configuration is identical to its own. However, it is
            sometimes desirable to start the cluster with only one
            management node (and perhaps to allow the other
      <a class="link" href="mysql-cluster-programs-ndb-mgmd.html" title="25.5.4 ndb_mgmd — The NDB Cluster Management Server Daemon">

         ndb_mgmd
        </strong>
       </span>
      </a>
      to be started later). This
            option causes the management node to bypass any checks for
            any other management nodes whose node IDs are passed to this
            option, permitting the cluster to start as though configured
            to use only the management node that was started.

      and
            running on the host having the IP address 198.51.100.150.
            (Suppose, for example, that the host computer on which you
            intend to the other management server is temporarily
            unavailable due to a hardware failure, and you are waiting
            for it to be repaired.) To start the cluster in this way,
            use a command line on the machine at 198.51.100.150 to enter
            the following command:

       <code class="option">

            at a later time without restarting the data nodes, you must
            start each data node with a connection string that

      Multiple management node IDs may be passed to this option as
            a comma-separated list. Each node ID must be no less than 1
            and no greater than 255. In practice, it is quite rare to
            use more than two management servers for the same NDB
            Cluster (or to have any need for doing so); in most cases
            you need to pass to this option only the single node ID for
            the one management server that you do not wish to use when
            starting the cluster.

     <p>
      NDB Cluster configuration data is stored internally rather
            than being read from the cluster global configuration file
            each time the management server is started (see
      <a class="xref" href="mysql-cluster-config-file.html" title="25.4.3 NDB Cluster Configuration Files">
       Section 25.4.3, “NDB Cluster Configuration Files”
      </a>
      ). Using this
            option forces the management server to check its internal
            data store against the cluster configuration file and to
            reload the configuration if it finds that the configuration
            file does not match the cache. Existing configuration cache
            files are preserved, but not used.
     </p>
     <p>
      This differs in two ways from the
      <a class="link" href="mysql-cluster-programs-ndb-mgmd.html#option_ndb_mgmd_initial">
       <code class="option">
        --initial
       </code>
      </a>
      option. First,
      <code class="option">
       --initial
      </code>
      causes all cache files to be
            deleted. Second,
      <code class="option">
       --initial
      </code>
      forces the
            management server to re-read the global configuration file
            and construct a new cache.
     </p>
     <p>
      If the management server cannot find a global configuration
            file, then the
      <code class="option">
       --reload
      </code>
      option is ignored.
     </p>
     <p>
      When
      <code class="option">
       --reload
      </code>
      is used, the management
            server must be able to communicate with data nodes and any
            other management servers in the cluster before it attempts
            to read the global configuration file; otherwise, the
            management server fails to start. This can happen due to
            changes in the networking environment, such as new IP
            addresses for nodes or an altered firewall configuration. In
            such cases, you must use
      <a class="link" href="mysql-cluster-programs-ndb-mgmd.html#option_ndb_mgmd_initial">
       <code class="option">
        --initial
       </code>
      </a>
      instead to force
            the existing cached configuration to be discarded and
            reloaded from the file. See
      <a class="xref" href="mysql-cluster-rolling-restart.html" title="25.6.5 Performing a Rolling Restart of an NDB Cluster">

   It is not strictly necessary to specify a connection string when
        starting the management server. However, if you are using more
        than one management server, a connection string should be
        provided and each node in the cluster should specify its node ID
        explicitly.
