25.5.21 ndb_print_sys_file — Print NDB System File Contents

ndb_print_sys_file obtains diagnostic information from an NDB Cluster system file.

Usage

ndb_print_sys_file file_name

filename is the name of a cluster system file (sysfile). Cluster system files are located in a data node's data directory (DataDir); the path under this directory to system files matches the patternndb_ _`#`__fs/D_`#`_/DBDIH/P_`#`_.sysfile. In each case, the # represents a number (not necessarily the same number). For more information, see NDB Cluster Data Node File System Directory.

Like ndb_print_backup_file andndb_print_schema_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_backup_file must be run on a 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.

Additional Options

None.
