MySQL

Note

We have a detailed howto for your first steps with SQL databases in DSS.

You might want to start with that Howto. The rest of this page is reference information for MySQL.

DSS supports the full range of features on MySQL:

  • Reading and writing datasets
  • Executing SQL recipes
  • Performing visual recipes in-database
  • Using live engine for charts

Caveats

  • TZ issue

Installing the driver

Secure connections (SSL / TLS) support

DSS can connect to a MySQL server using secure connections.

Importing the server certificate and creating the client certificate

Please follow the instructions laid out here:

https://dev.mysql.com/doc/connector-j/5.1/en/connector-j-reference-using-ssl.html

You may need to add the root certificate of the authority which issued the MySQL server certificate to the JVM truststore using one of the procedures described at Adding SSL certificates to the Java truststore.

Additionally, if a client certificate is used, the keystore file and password used by DSS to authenticate to the MySQL server need to be specified with additional Java options -Djavax.net.ssl.keyStore=path_to_keystore_file -Djavax.net.ssl.keyStorePassword=password.

Your install.ini file should therefore look like:

[javaopts]
backend.additional.opts=-Djavax.net.ssl.keyStore=path_to_keystore_file -Djavax.net.ssl.keyStorePassword=password -Djavax.net.ssl.trustStore=path_to_truststore_file -Djavax.net.ssl.trustStorePassword=password
jek.additional.opts=-Djavax.net.ssl.keyStore=path_to_keystore_file -Djavax.net.ssl.keyStorePassword=password -Djavax.net.ssl.trustStore=path_to_truststore_file -Djavax.net.ssl.trustStorePassword=password
fek.additional.opts=-Djavax.net.ssl.keyStore=path_to_keystore_file -Djavax.net.ssl.keyStorePassword=password -Djavax.net.ssl.trustStore=path_to_truststore_file -Djavax.net.ssl.trustStorePassword=password

Setting up the MySQL connection

In the settings of the connection, add an “Advanced property”:

  • Key: useSSL
  • Value: true
