Important upgrade information

RapidMiner Server version 7.4 fixes a rare error for high frequent scheduled processes. Using the Full Server Package installation method, these is applied automatically. However, if you are using an EAR file to upgrade an existing installation that uses MySQL, an additional step is necessary to benefit from these improvements. For other databases (e.g., MS-SQL, Oracle, and PostgreSQL), no configuration changes are needed.

  1. Edit the file standalone/configuration/standalone.xml in the RapidMiner Server installation directory.

  2. Locate the data source subsystem element, for example:

     <datasource jta="true" jndi-name="java:/jdbc/RapidAnalyticsDS" pool-name="RapidAnalyticsDS" enabled="true" use-java-context="false" use-ccm="true">
        
     <connection-url>jdbc:mysql://localhost:3306/rapidminer_server</connection-url>
        
     <driver>mysql-connector-java-5.1.31.jar</driver>
     .
     .
     .
     </datasource>
    
  3. Add the following line to the <datasource></datasource> element:

     <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
    
  4. Save the file and restart RapidMiner Server.
