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.
