It remains under development, and its syntax and behavior are subject to change in future releases. For this reason, it should be considered experimental at this time. +.PP +The C++ source files for +\fBndbd_redo_log_reader\fR +can be found in the directory +\fI/storage/ndb/src/kernel/blocks/dblqh/redoLogReader\fR. +.PP +\fBUsage\fR: +.sp +.RS 3n +.nf +ndbd_redo_log_reader \fIfile_name\fR [\fIoptions\fR] +.fi +.RE +.PP +\fIfile_name\fR +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 +\fIndb_\fR\fI\fI#\fR\fR\fI_fs/D\fR\fI\fI#\fR\fR\fI/LCP/\fR\fI\fI#\fR\fR\fI/T\fR\fI\fI#\fR\fR\fIF\fR\fI\fI#\fR\fR\fI.Data\fR.

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. +.SH "COPYRIGHT" +.PP +Copyright 2007\-2008 MySQL AB, 2009 Sun Microsystems, Inc. +.PP +This documentation is free software; you can redistribute it and/or modify it only under the terms of the GNU General Public License as published by the Free Software Foundation; version 2 of the License. +.PP +This documentation is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
