ndb_mgmd — The NDB Cluster Management Server Daemon configuration cache files manually, then restart the management server with  --skip-config-cache (or with  --config-cache  set equal to 0,  OFF , or  FALSE ). Configuration cache files are normally created in a directory named  mysql-cluster  under the installation directory (unless this location has been overridden using the  --configdir  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: node-id  is the management server’s node ID;  seq-number  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  ndb_5_config.bin.1 ,  ndb_5_config.bin.2 , and ndb_5_config.bin.3 . If your intent is to purge or reload the configuration cache without actually disabling caching, you should start  ndb_mgmd  with one of the options  --reload  or  --initial  instead of  --skip-config-cache . To re-enable the configuration cache, simply restart the management server, but without the  --config- cache  or  --skip-config-cache  option that was used previously to disable the configuration cache. ndb_mgmd  does not check for the configuration directory ( --configdir ) or attempts to create one when  --skip-config-cache  is used. (Bug #13428853) 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 has no default value, and is ignored unless the management server is forced to read the configuration file, either because  ndb_mgmd  was started with the  --reload  or  --initial  option, or because the management server could not find any configuration cache. Beginning with NDB 8.0.26, ndb_mgmd  refuses to start if  --config-file  is specified without either of  --initial  or  --reload . The  --config-file  option is also read if  ndb_mgmd  was started with  --config-cache=OFF . See Section 23.3.3, “NDB Cluster Configuration Files” , for more information. • --configdir= dir_name • --config-file= filename ,  -f  filename ndb_ node-id _config.bin. seq-number Command-Line Format --config-file=file Disabled by skip-config-file Type File name Default Value [none] Command-Line Format --configdir=directory --config-dir=directory Type File name 4259
