Comparing Cluster Members

Does anyone know of a good utility that will do a binary compare of all the files on two cluster members? We are looking for something we can run on a monthly batch basis to monitor for configuration drift between AIX/HACMP and Solaris/VCS cluster member pairs, use as an ad hoc diagnostic tool when an app runs fine on one cluster node but not the other, or to compare test and prod systems to figure out why a problem cannot be reproduced in the test environment.

I realize tight system management procedures are the best preventative, but when you have eight sysadmins with root (sudo) access and another dozen people with varying access to app directories, some type of drift is inevitable. We need something that can at least help us prove that the machines are identical so we can direct diagnostic efforts back to the application.

ndb_print_backup_file

NDB_PRINT_BACKUP_(1)					       MySQL Database System					      NDB_PRINT_BACKUP_(1)

NAME

       ndb_print_backup_file - print NDB backup file contents

SYNOPSIS

       ndb_print_backup_file file_name

DESCRIPTION

       ndb_print_backup_file obtains diagnostic information from a cluster backup file.
	       Usage

	   ndb_print_backup_file file_name

       file_name is the name of a cluster backup file. This can be any of the files (.Data, .ctl, or .log file) found in a cluster backup
       directory. These files are found in the data node's backup directory under the subdirectory BACKUP-#, where # is the sequence number for
       the backup. For more information about cluster backup files and their contents, see Section 17.5.3.1, "MySQL Cluster Backup Concepts".

       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_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.
