SYNOPSIS
       ndb_mgmd options

DESCRIPTION
       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.

       The following list includes options that are specific to ndb_mgmd. For
       options common to all NDB programs, see Section 17.6.2, "Options Common
       to MySQL Cluster Programs".

       o  --config-file=filename, -f filename

          +--------------------+-----------------+
          |Command Line Format | -f              |
          +--------------------+-----------------+
          |Value Set           | [nested table]* |
          +--------------------+-----------------+

       *[nested table]
       +--------+----------+
       |Type    | filename |
       +--------+----------+
       |Default |          |
       +--------+----------+
       Instructs the management server as to which file it should use for its
       configuration file. By default, the management server looks for a file
       named config.ini in the same directory as the ndb_mgmd executable;
       otherwise the file name and location must be specified explicitly.

       This option also can be given as -c file_name, but this shortcut is
       obsolete and should not be used in new installations.

       o  --daemon, -d

          +--------------------+-----------------+
          |Command Line Format | --daemon        |
          +--------------------+-----------------+
          |Value Set           | [nested table]* |
          +--------------------+-----------------+

       *[nested table]
       +--------+---------+
       |Type    | boolean |
       +--------+---------+
       |Default | TRUE    |
       +--------+---------+
       Instructs ndb_mgmd to start as a daemon process. This is the default
       behavior.

       |Default | FALSE   |
       +--------+---------+
       Instructs ndb_mgmd not to start as a daemon process.

       o  --print-full-config, -P

          +--------------------+---------------------+
          |Version Introduced  | 5.0.10              |
          +--------------------+---------------------+
          |Command Line Format | --print-full-config |
          +--------------------+---------------------+
          |Value Set           | [nested table]*     |
          +--------------------+---------------------+

       *[nested table]
       +--------+---------+
       |Type    | boolean |
       +--------+---------+
       |Default | FALSE   |
       +--------+---------+
       Shows extended information regarding the configuration of the cluster.
       With this option on the command line the ndb_mgmd process prints
       information about the cluster setup including an extensive list of the
       cluster configuration sections as well as parameters and their values.
       Normally used together with the --config-file (-f) option.


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

See Section 17.3.4.2, "The MySQL Cluster Connectstring", for information about
using connectstrings.  ndb_mgmd(8), describes other options for ndb_mgmd.

The following files are created or used by ndb_mgmd in its starting directory,
and are placed in the DataDir as specified in the config.ini configuration
file. In the list that follows, node_id is the unique node identifier.

o  config.ini is the configuration file for the cluster as a whole. This file
   is created by the user and read by the management server.  Section 17.3,
   "MySQL Cluster Configuration", discusses how to set up this file.

o  ndb_node_id_cluster.log is the cluster events log file. Examples of such
   events include checkpoint startup and completion, node startup events, node
   failures, and levels of memory usage. A complete listing of cluster events
   with descriptions may be found in Section 17.7, "Management of MySQL
   Cluster".

   When the size of the cluster log reaches one million bytes, the file is
   renamed to ndb_node_id_cluster.log.seq_id, where seq_id is the sequence
   number of the cluster log file. (For example: If files with the sequence
   numbers 1, 2, and 3 already exist, the next log file is named using the
   number 4.)
