NDBD_REDO_LOG_REA(1)		      MySQL Database System		     NDBD_REDO_LOG_REA(1)

NAME
       ndbd_redo_log_reader - check and print content of cluster redo log

SYNOPSIS
       ndbd_redo_log_reader file_name [options]

DESCRIPTION
       Reads a redo log file, checking it for errors, printing its contents in a human-readable
       format, or both.  ndbd_redo_log_reader is intended for use primarily by MySQL Cluster
       developers and Support personnel in debugging and diagnosing problems.

       This utility remains under development, and its syntax and behavior are subject to change
       in future MySQL Cluster releases.

       The C++ source files for ndbd_redo_log_reader can be found in the directory
       /storage/ndb/src/kernel/blocks/dblqh/redoLogReader.

       The following table includes options that are specific to the MySQL Cluster program
       ndbd_redo_log_reader. Additional descriptions follow the table. For options common to most
       MySQL Cluster programs (including ndbd_redo_log_reader), see Options Common to MySQL
       Cluster Programs(1).

	       Usage

	   ndbd_redo_log_reader file_name [options]

       file_name is the name of a cluster redo log file. redo log files are located in the
       numbered directories under the data node's data directory (DataDir); the path under this
       directory to the redo log files matches the pattern ndb_#_fs/D#/LCP/#/T#F#.Data. In each
       case, the # represents a number (not necessarily the same number). For more information,
       see MySQL Cluster Data Node FileSystemDir Files[1].

       The name of the file to be read may be followed by one or more of the options listed here:

	   Added in MySQL Cluster NDB 7.2.15. (Bug #11749591, Bug #36805)

       Like ndb_print_backup_file and ndb_print_schema_file (and unlike most of the NDB utilities
       that are intended to be run on a management server host or to connect to a management
       server) ndbd_redo_log_reader 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.
