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".
