#
# This test uses a configuration with
# 250 MySQL Servers
# 1 Management server
# 2 Data nodes
#
# Running this test requires a fairly large machine. It
# also uses quite a lot of ports for all the started processes
# and to avoid port conflicts the X plugin is disabled in order
# to allow using also those ports
#
# NOTE! Currently mtr.pl need to be started with --no-check-testcases
# which time-out otherwise, also the "shutdown step" step is taking
# long time so using --shutdown-timeout=0 and --no-warnings is
# recommended.
#
# $> mtr.pl test_250_mysqld --no-check-testcases \
# --shutdown-timeout=0 --no-warnings
#
# The test can also be used just for starting a cluster:
# $1> mtr.pl ndb_big.test_250_mysqld --start
#
# $2> mysql --defaults-file=bld/mysql-test/var/my.cnf
#
#
--source include/not_parallel.inc
--source include/have_ndb.inc
# Total number of nodes
SELECT COUNT(*) as Nodes_in_cluster FROM ndbinfo.processes;
# Total number of MySQL Servers
SELECT COUNT(*) as MySQL_Servers FROM ndbinfo.processes
WHERE process_name = 'mysqld';
#
# The very basic test
# - showing table can be created in the storage engine NDB
# - read and write the table
#
CREATE TABLE t1 (
a int PRIMARY KEY,
b varchar(255)

INSERT INTO t1 VALUES (1, "MySQL Server with NDB");
INSERT INTO t1 (a, b) VALUES (11, "Barrier effect");
INSERT INTO t1 (a, b) VALUES
