You can troubleshoot an issue that you encounter while you run a performance test with a
MySQL database.
About this task
If you are using MySQL version 5.7 or later, the SQL mode ONLY_FULL_GROUP_BY is
enabled by default. This mode must be removed, otherwise, when you run a performance test from
Rational®
Integration Tester with
a MySQL database, an error is reported for the GROUP BY clause.
To remove this mode, follow these steps:
Procedure
-
For Windows or Linux follow these steps:
-
Edit the MySQL configuration file
my.ini
on Windows or
my.cnf
on Linux. Set the sql_mode
parameter from a command
line in one of two ways:
sql_mode="STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION"
sql_mode=""
-
Restart the MySQL server.
-
For Ubuntu follow these steps:
- Create the following file:
/etc/mysql/conf.d/disable_strict_mode.cnf
- Edit the file. Copy and paste the following command into the
disable_strict_mode.cnf
file to set the sql_mode
parameter:
[mysqld]
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
- Restart the MySQL server.
sudo service mysql restart
- Check that the mode was removed:
mysql> select @@sql_mode
The result shows you the
following:
STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
