# This programs tries to find all limits for a sql server
# It gets the name from what it does to most servers :)
#
# Be sure to use --help before running this!
#
# If you want to add support for another server, add a new package for the
# server in server-cfg.  You only have to support the 'new' and 'version'
# functions. new doesn't need to have any limits if one doesn't want to
# use the benchmarks.

# TODO:
# CMT includes types and functions which are synonyms for other types
# and functions, including those in SQL9x. It should label those synonyms
# as such, and clarify ones such as "mediumint" with comments such as
# "3-byte int" or "same as xxx".

This program tries to find all limits and capabilities for a SQL
server.  As it will use the server in some 'unexpected' ways, one
shouldn\'t have anything important running on it at the same time this
program runs!  There is a slight chance that something unexpected may
happen....

As all used queries are legal according to some SQL standard. any
reasonable SQL server should be able to run this test without any
problems.

All questions is cached in $opt_dir/'server_name'.cfg that future runs will use
limits found in previous runs. Remove this file if you want to find the
current limits for your version of the database server.

This program uses some table names while testing things. If you have any
tables with the name of 'crash_me' or 'crash_qxxxx' where 'x' is a number,
they will be deleted by this test!

$0 takes the following options:

--help or --Information
  Shows this help

--batch-mode
  Don\'t ask any questions, quit on errors.

--comment='some comment'
  Add this comment to the crash-me limit file

2273 2274 2275 2276 2277
--check-server
  Do a new connection to the server every time crash-me checks if the server
  is alive.  This can help in cases where the server starts returning wrong
  data because of an earlier select.

--database='database' (Default $opt_database)
  Create test tables in this database.

--dir='limits'
  Save crash-me output in this directory

--debug
  Lots of printing to help debugging if something goes wrong.

--fix-limit-file
  Reformat the crash-me limit file.  crash-me is not run!

--force
  Start test at once, without a warning screen and without questions.
  This is a option for the very brave.
  Use this in your cron scripts to test your database every night.

--log-all-queries
  Prints all queries that are executed. Mostly used for debugging crash-me.

--log-queries-to-file='filename'
  Log full queries to file.

--host='hostname' (Default $opt_host)
  Run tests on this host.

--password='password'
  Password for the current user.

--restart
  Save states during each limit tests. This will make it possible to continue
  by restarting with the same options if there is some bug in the DBI or
  DBD driver that caused $0 to die!

--server='server name'  (Default $opt_server)
  Run the test on the given server.
  Known servers names are: Access, Adabas, AdabasD, Empress, Oracle, Informix, DB2, Mimer, mSQL, MS-SQL, MySQL, Pg, Solid or Sybase.
  For others $0 can\'t report the server version.

--user='user_name'
  User name to log into the SQL server.

--start-cmd='command to restart server'
2321
  Automaticly restarts server with this command if the database server dies.

To make this test easier, start mSQL in another terminal with something like:

If you are running Solid without logging and/or backup YOU WILL LOSE!
Solid does not write data from the cache often enough. So if you continue
you may lose tables and data that you entered hours ago!

Solid will also take a lot of memory running this test. You will nead
at least 234M free!

When doing the connect test Solid server or the perl api will hang when
freeing connections. Kill this program and restart it to continue with the

not uncommon that either this crash-me test program, or the actual
database back-end, will DIE with an out-of-memory error. So might
any other program on your system if it requests more memory at the
wrong time.

Note also that while crash-me tries to find limits for the database server
2410
it will make a lot of queries that can\'t be categorized as \'normal\'.  It\'s

not unlikely that crash-me finds some limit bug in your server so if you
run this test you have to be prepared that your server may die during it!

We, the creators of this utility, are not responsible in any way if your
database server unexpectedly crashes while this program tries to find the
