Users of earlier NDB Cluster versions should note that some of these options have been changed to make them consistent with one another as well as with
\fBmysqld\fR\&. You can use the
\fB\-\-help\fR
option with any NDB Cluster program\(emwith the exception of
\fBndb_print_backup_file\fR,
\fBndb_print_schema_file\fR, and
\fBndb_print_sys_file\fR\(emto view a list of the options which the program supports\&.

The options in the following table are common to all NDB Cluster executables (except those noted previously in this section)\&.

Prints the NDB Cluster version number of the executable\&. The version number is relevant because not all versions can be used together, and the NDB Cluster startup process verifies that the versions of the binaries being used can co\-exist in the same cluster\&. This is also important when performing an online (rolling) software upgrade or downgrade of NDB Cluster\&.
