Supported Databases

MySQL Community Server

- Versions: 5.6 and 5.7 series
- JDBC Driver Version: 5.1.40. Download: Here

Prerequisites

Check whether your version of MySQL is supported
If you are upgrading from Zephyr 4.7, a MySQL Database will already be present, so you won't need to install this again
Have an installation of MySQL ready
Ensure the JDBC driver is stored locally on the Application Server where Zephyr will be installed

Configure the MySQL Database

The following steps will need to be followed:

Step 1: Login to your MySQL Server
Step 2: Create a new user for Zephyr
Step 3: Set permissions for remote access
Step 4: Set Memory and Max Connections
Step 5: Install Zephyr and Connect to the Database

Step 1: Login to your MySQL Server

Open command prompt and navigate to your MySQL installation folder (i.e. C:\Program Files\MySQL\MySQL Server 5.6\bin)

Establish connection to your MySQL server by using the command:

mysql.exe -uroot

In this example the username is root. In a new MySQL instance, root is the default user and can be logged in without a password. If you are using an existing MySQL Server instance, the username and password may be different.

Step 2: Create a new user for Zephyr

Create a new database user which Zephyr will connect as. The command to create a new user is seen below:

CREATE USER 'zephyrDBuser@'localhost' IDENTIFIED BY 'zephyrDBuserPass';

Step 3: Set permissions for remote access

Now type the below command to make the Database accessible remotely.

grant all on *.* to zephyrDBuser@'127.0.0.1' identified by 'zephyrDBUserPass';

zephyrDBuser represents the username and ZephyrDBuserPass is the password for the newly created user from Step 2.

The '*.*' is granting permissions to all databases. Replace 127.0.01 with the IP address of the server Zephyr will be installed on. This command will grant access to ALL databases for the IP addresses given. The minimum permission requirement are the privileges to create and populate tables.

If you are installing the database with data center in mind, you will need to grant permissions for each node in the cluster.

Checking permissions

To check permissions for all users run the following command:

SELECT * from information_schema.user_privileges;

Now you an access your MySQL database remotely from the designated IP(s).

Step 4: Set Memory and Max Connections

Navigate to the my.ini file (Windows) or my.cnf (Linux), the default locations are the MySQL root folders.

Set the following values for the parameters:

Parameter	Minimum value
innodb_buffer_pool_size=	4096M
query_cache_size=	1M
key_buffer_size=	8M
max_connections=	500

If no lines contain these parameters, then create new lines for them.

Queries for checking Memory

To check values of a parameter, use the following SQL queries:

SELECT @@innodb_buffer_pool_size;

SHOW VARIABLES LIKE 'query_cache_size';

SHOW VARIABLES LIKE ' key_buffer_size ';

SHOW VARIABLES LIKE 'max_connections';

Step 5: Install Zephyr and Connect to the Database

Now the MySQL database is ready, open the Zephyr installer. The wizard will take you through the setup steps.

Note

MySQL Logging

If you are having problems with your MySQL database after making these changes, please consult your OS's application logs for issue details.
