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:
o

| +---------+---------+

--help: Print usage information.
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.
