NAME
       ndb_mgm - the MySQL Cluster management client

SYNOPSIS
       ndb_mgm options

DESCRIPTION
       The ndb_mgm management client process is actually not needed to run the cluster. Its value
       lies in providing a set of commands for checking the cluster's status, starting backups,
       and performing other administrative functions. The management client accesses the
       management server using a C API. Advanced users can also employ this API for programming
       dedicated management processes to perform tasks similar to those performed by ndb_mgm.

       To start the management client, it is necessary to supply the host name and port number of
       the management server:

	   shell> ndb_mgm [host_name [port_num]]

       For example:

	   shell> ndb_mgm ndb_mgmd.mysql.com 1186

       The default host name and port number are localhost and 1186, respectively.

       The following table includes options that are specific to the MySQL Cluster management
       client program ndb_mgm. Additional descriptions follow the table. For options common to
       most MySQL Cluster programs (including ndb_mgm), see Options Common to MySQL Cluster
       Programs(1).

       +-----------------------+--------------------------+-----------------------+

       o   --execute=command, -e command

	   +--------------------+----------------+
	   |Command-Line Format | --execute=name |
	   +--------------------+----------------+
	   |			| -e		 |
	   +--------------------+----------------+
	   This option can be used to send a command to the MySQL Cluster management client from
	   the system shell. For example, either of the following is equivalent to executing SHOW
	   in the management client:

	       shell> ndb_mgm -e "SHOW"
	       shell> ndb_mgm --execute="SHOW"

	   This is analogous to how the --execute or -e option works with the mysql command-line
	   client. See Section 4.2.3.1, "Using Options on the Command Line".

	       Note
	       If the management client command to be passed using this option contains any space
	       characters, then the command must be enclosed in quotation marks. Either single or
	       double quotation marks may be used. If the management client command contains no
	       space characters, the quotation marks are optional.

       o   --try-reconnect=number

	   +--------------------+-------------------+
	   |Command-Line Format | --try-reconnect=# |
	   +--------------------+-------------------+
	   |			| -t		    |
	   +--------------------+-------------------+
	   |			| Permitted Values  |
	   |			+---------+---------+
	   |			| Type	  | boolean |
	   |			+---------+---------+
	   |			| Default | TRUE    |
	   +--------------------+---------+---------+
	   If the connection to the management server is broken, the node tries to reconnect to
	   it every 5 seconds until it succeeds. By using this option, it is possible to limit
	   the number of attempts to number before giving up and reporting an error instead.

       Additional information about using ndb_mgm can be found in Section 17.5.2, "Commands in
       the MySQL Cluster Management Client".
