NDB_SIZE.PL(1)


NAME

  ndb_size.pl - NDBCluster Size Requirement Estimator


SYNOPSIS

  ndb_size.pl arguments


DESCRIPTION

  This is a Perl script that can be used to estimate the amount of space that
  would be required by a MySQL database if it were converted to use the
  NDBCluster storage engine. Unlike the other utilities discussed in this
  section, it does not require access to a MySQL Cluster (in fact, there is
  no reason for it to do so). However, it does need to access the MySQL
  server on which the database to be tested resides.

  Requirements:

  ·  A running MySQL server. The server instance does not have to provide
     support for MySQL Cluster.

  ·  A working installation of Perl.

  ·  The DBI and HTML::Template modules, both of which can be obtained from
     CPAN if they are not already part of your Perl installation. (Many Linux
     and other operating system distribution provide their own packages for
     one or both of these libraries.)

  ·  The ndb_size.tmpl template file, which you should be able to find in the
     share/mysql directory of your MySQL installation. This file should be
     copied or moved into the same directory as ndb_size.pl - if it is not
     there already - before running the script.

  ·  A MySQL user account having the necessary privileges. If you do not wish
     to use an existing account, then creating one using GRANT USAGE ON
     db_name.* - where db_name is the name of the database to be examined -
     is sufficient for this purpose.

  ndb_size.pl and ndb_size.tmpl can also be found in the MySQL sources in
  storage/ndb/tools. If these files are not present in your MySQL
  installation, you can obtain them from the [1]MySQLForge project page.

  Usage:

     perl ndb_size.pl db_name hostname username password > file_name.html

  The command shown connects to the MySQL server at hostname using the
  account of the user username having the password password, analyses all of
  the tables in database db_name, and generates a report in HTML format which
  is directed to the file file_name.html. (Without the redirection, the
  output is sent to stdout.) This figure shows partial sample output as
  viewed in a Web browser:

  The output from this script includes:

  ·  Minimum values for the DataMemory, IndexMemory, MaxNoOfTables,
     MaxNoOfAttributes, MaxNoOfOrderedIndexes, MaxNoOfUniqueHashIndexes, and
     MaxNoOfTriggers configuration parameters required to accommodate the
     tables analysed.

  ·  Memory requirements for all of the tables, attributes, ordered indexes,
     and unique hash indexes defined in the database.

  ·  The IndexMemory and DataMemory required per table and table row.
