ndb_mgm — The NDB Cluster Management Client • --defaults-extra-file • --defaults-file • --execute=command ,  -e command • --encrypt-backup • --defaults-group-suffix Read given file after global files are read. Read default options from given file only. Also read groups with concat(group, suffix). When used, this option causes all backups to be encrypted. To make this happen whenever  ndb_mgm  is run, put the option in the  [ndb_mgm]  section of the  my.cnf  file. This option can be used to send a command to the NDB 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" Command-Line Format --execute=name Command-Line Format --encrypt-backup[=TRUE|FALSE] Introduced 8.0.24-ndb-8.0.24 Type Boolean Default Value TRUE Command-Line Format --defaults-group-suffix=string Type String Default Value [none] Command-Line Format --defaults-file=path Type String Default Value [none] Command-Line Format --defaults-extra-file=path Type String Default Value [none] This is analogous to how the  --execute  or  -e  option works with the  mysql  command-line client. See Section 4.2.2.1, “Using Options on the Command Line” . 4271 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.
