25.5.18 ndb_print_file — Print NDB Disk Data File Contents

ndb_print_file obtains information from an NDB Cluster Disk Data file.

Usage

ndb_print_file [-v] [-q] file_name+

file_name is the name of an NDB Cluster Disk Data file. Multiple filenames are accepted, separated by spaces.

Like ndb_print_schema_file and ndb_print_sys_file (and unlike most of the other NDB utilities that are intended to be run on a management server host or to connect to a management server) ndb_print_file must be run on an NDB Cluster data node, since it accesses the data node file system directly. Because it does not make use of the management server, this utility can be used when the management server is not running, and even when the cluster has been completely shut down.

• --file-key, -K

  Command-Line Format	--file-key=hex_data
