Management clients-opracowanie

Management clients. These clients connect to the management server and provide commands
for starting and stopping nodes gracefully, starting and stopping message tracing (debug versions
only), showing node versions and status, starting and stopping backups, and so on. An example of this
type of program is the ndb_mgm management client supplied with MySQL Cluster (see Section 17.4.5,
“ndb_mgm — The MySQL Cluster Management Client”). Such applications can be written using
the MGM API, a C-language API that communicates directly with one or more MySQL Cluster
management servers. For more information, see The MGM API.
Oracle also makes available MySQL Cluster Manager, which provides an advanced command-line
interface simplifying many complex MySQL Cluster management tasks, such restarting a MySQL
Cluster with a large number of nodes. The MySQL Cluster Manager client also supports commands for
getting and setting the values of most node configuration parameters as well as mysqld server options
and variables relating to MySQL Cluster. MySQL Cluster Manager 1.1 provides support for adding data
nodes online. See the MySQL Cluster Manager User Manual, for more information.
